Interstitial fluid pressure in normal and inflamed pulp. (1/75)

Tissue pressure is the hydrostatic pressure in the interstitial fluid which surrounds the pulpal cells. This pressure outside the vessels is normally considerably lower than the blood pressure inside the vessels. The dental pulp has a relatively low interstitial compliance due to its enclosure between rigid dentin walls. Accordingly, even a modest increase in pulpal fluid volume will raise the tissue pressure, which may compress blood vessels, leading to ischemia and necrosis. Inflammation may lead to an increase in both interstitial fluid volume and blood volume in the low-compliant pulp and thereby increase the tissue pressure. However, the increased tissue pressure may, in turn, initiate increased lymph flow and absorption of fluid into capillaries in nearby non-inflamed tissue. Both of these latter factors will transport fluid out of the affected area and subsequently out of the tooth and consequently lower the tissue pressure. Increased tissue pressure, whether caused by increased blood volume or increased capillary filtration, will promote outward flow of fluid through exposed dentin tubules and thereby help to protect the pulp against entry of harmful substances. It seems physiologically beneficial, therefore, for the pulp to have a high tissue pressure, which promptly increases when blood flow increases due to its low compliance.  (+info)

Evidence for bacterial causation of adverse pulpal responses in resin-based dental restorations. (2/75)

The widespread use of resin and resin-monomers for bonding of dental restorations to dentin has occurred because of a fundamental shift in the view that injury to the pulp is induced by restorative procedures. While, for many years, the toxic effects of restorative materials were thought to be of crucial importance in the development of adverse pulpal responses, the key role of bacterial leakage at the restoration-tooth interface is now well-recognized. Consequently, if optimal conditions for the preservation of pulpal health are to be ensured, dental restorations should provide an impervious seal against the surrounding tooth structure. However, polymerization shrinkage and contraction stresses induced during setting, as well as a variety of technical difficulties encountered during the clinical operation, often produce less than perfect results. Therefore, modern restorative procedures involving resin and resin-bonded restoratives must still rely on the ability of the pulp to cope with the injurious elements to which it may be exposed during and after the procedure. This review examines factors that may govern the pulp's response to restorative procedures that involve adhesive technologies. An assessment is made of the risks involved as far as the continued vital function of the pulp is concerned. It is concluded that an intact, although thin, wall of primary dentin often enables the pulp to overcome both toxic material effects and the influences of bacterial leakage. In contrast, the pulp may not do equally well following capping of open exposures with resin composites. A dearth of controlled clinical studies in this area of dentistry calls for confirmation that pulpal health prevails over the long term following the use of total-etch and resin-bonding techniques.  (+info)

Taxonomic characterization of Mogibacterium diversum sp. nov. and Mogibacterium neglectum sp. nov., isolated from human oral cavities. (3/75)

Novel isolates, strains HM-7, HM-6, HH-31, P9a-hT and UJB13-d, which were isolated from tongue plaque and necrotic dental pulp, were studied taxonomically and phylogenetically. These organisms were anaerobic, non-spore-forming, gram-positive, rod-shaped bacteria that were inert in most of the conventional biochemical tests and phenotypically resemble Mogibacterium species or asaccharolytic Eubacterium species. The G+C contents of the DNAs from the novel isolates ranged from 41 to 42 mol %. DNA-DNA hybridization studies demonstrated that these strains might be assigned to the genus Mogibacterium but not to the previously described species. It was also apparent that strain HM-7 belonged to the same species as strains HM-6 and HH-31, and that strains P9a-hT and UJB13-d belonged to a second species. The levels of DNA-DNA relatedness to asaccharolytic Eubacterium species, including Eubacterium brachy, Eubacterium nodatum, Eubacterium saphenum and the more recently proposed Eubacterium minutum and Eubacterium exiguum (reclassified as Slackia exigua), are less than 2%. The results of 16S rDNA sequence comparisons revealed that these organisms represent novel lineages distinct from all previously described species of gram-positive, rod-shaped bacteria. On the basis of phenotypic characteristics, DNA-DNA hybridization data and phylogenetic analysis with 16S rRNA gene sequence data, new species are proposed, namely Mogibacterium diversum (for strains HM-7, HM-6 and HH-31) and Mogibacterium neglectum (for strains P9a-hT and UJB13-d). HM-7T (= ATCC 700923T = JCM 11205T) is the type strain of the former and P9a-hT (= ATCC 700924T = JCM 11204T) is the type strain for the latter.  (+info)

PCR-based identification of bacteria associated with endodontic infections. (4/75)

PCR primers that target the bacterial 16S rRNA genes (or the tuf gene for the genus Enterococcus) were used to identify 10 putative bacterial pathogens in root canals with necrotic pulp. In addition, the associations of these microorganisms with symptoms and a history of diabetes mellitus were investigated. Microbial samples from the root canals of 24 teeth with necrotic pulp were included in the study. PCR with universal bacterial primers identified bacterial DNA in 22 specimens; the remaining 2 specimens were from intact teeth that had been traumatized 6 months prior to treatment. PCR with specific primers showed that preoperative symptoms were significantly associated with the presence of Streptococcus spp. (P < 0.001 by chi-square analysis). There was also a nonsignificant trend for symptoms to be associated with Fusobacterium nucleatum and Porphyromonas gingivalis (odds ratio, >2) and for diabetes mellitus to be associated with P. gingivalis and Porphyromonas endodontalis (odds ratio, >2). Cloning and sequencing of the universal PCR product in one specimen revealed the presence of an organism related to the genus Olsenella, which has not previously been described in endodontic infections.  (+info)

Yeasts in apical periodontitis. (5/75)

Microbiological reports of apical periodontitis have revealed that yeasts can be isolated from approximately 5-20% of infected root canals. They occur either in pure cultures or together with bacteria. Almost all isolated yeasts belong to the genus Candida, and the predominant species is C. albicans. Pheno- and genotypic profiles of C. albicans isolates show heterogeneity comparable with those of isolates from other oral sites. C. albicans expresses several virulence factors that are capable of infecting the dentin-pulp complex, including dentinal tubules. This causes, consequentially, an inflammatory response around the root apex, which suggests a pathogenic role for this organism in apical periodontitis. Yeasts are particularly associated with persistent root canal infections that do not respond favorably to conservative root canal therapy. This may be due to the resistance of all oral Candida species against a commonly used topical medicament, calcium hydroxide. However, other antimicrobial agents may offer alternative therapeutic approaches and improve the treatment of these persistent cases of apical periodontitis.  (+info)

Prevalence of microorganisms in root canals of human deciduous teeth with necrotic pulp and chronic periapical lesions. (6/75)

The objective of this study was to evaluate bacterial prevalence in 31 root canals of human deciduous teeth with necrotic pulp and periapical lesions using bacterial culture. After crown access, the material was collected using absorbent paper points for microbiological evaluation and determination of colony forming units (CFU). Anaerobic microorganisms were found in 96.7% of the samples, black-pigmented bacilli in 35.5%, aerobic microorganisms in 93.5%, streptococci in 96.7%, and S. mutans in 48.4%. We concluded that in human deciduous teeth root canals with necrotic pulp and periapical lesions the infection is polymicrobial, with a large number of microorganisms and a predominance of streptococci and anaerobic microorganisms.  (+info)

Pathogenesis of apical periodontitis and the causes of endodontic failures. (7/75)

Apical periodontitis is a sequel to endodontic infection and manifests itself as the host defense response to microbial challenge emanating from the root canal system. It is viewed as a dynamic encounter between microbial factors and host defenses at the interface between infected radicular pulp and periodontal ligament that results in local inflammation, resorption of hard tissues, destruction of other periapical tissues, and eventual formation of various histopathological categories of apical periodontitis, commonly referred to as periapical lesions. The treatment of apical periodontitis, as a disease of root canal infection, consists of eradicating microbes or substantially reducing the microbial load from the root canal and preventing re-infection by orthograde root filling. The treatment has a remarkably high degree of success. Nevertheless, endodontic treatment can fail. Most failures occur when treatment procedures, mostly of a technical nature, have not reached a satisfactory standard for the control and elimination of infection. Even when the highest standards and the most careful procedures are followed, failures still occur. This is because there are root canal regions that cannot be cleaned and obturated with existing equipments, materials, and techniques, and thus, infection can persist. In very rare cases, there are also factors located within the inflamed periapical tissue that can interfere with post-treatment healing of the lesion. The data on the biological causes of endodontic failures are recent and scattered in various journals. This communication is meant to provide a comprehensive overview of the etio-pathogenesis of apical periodontitis and the causes of failed endodontic treatments that can be visualized in radiographs as asymptomatic post-treatment periapical radiolucencies.  (+info)

Fiber optic fluorescence microprobe for endodontic diagnosis. (8/75)

Successful endodontic therapy requires total debridement as well as complete obturation of the root canal to the cemento-dentinal junction. The goal of this study was to investigate the feasibility of using quantitative fluorescence spectroscopy for the detection and localization of pathological dentin, pulpal remnants, and microorganisms within the root canal. Specific aims were to identify: 1) characteristic excitation/emission spectra for healthy dentin, decayed dentin, enamel, and pulp; 2) the potential of specific spectral data for differentiating between these tissues; and 3) the potential of spectral data for detecting the presence and identifying four common endodontic pathogens. Fluorescence spectra were determined in the tissues of permanent human teeth, extirpated healthy and necrotic pulps, and four endodontic pathogens. Excitation/emission spectra were collected at 366 nm, 405 nm, and 440 nm excitation. Marked differences in spectral signatures between the different tissues under investigation were observed. We postulate that the differences in fluorescence spectra of decayed vs. healthy dentin are due to the loss of mineralized tissue components and increased organic presence and water in these tissues. Pulpal tissue showed distinctly different fluorescence spectra from healthy and decayed dentin, providing a basis for differentiating between tissue categories. Each bacterial species demonstrated distinct spectral emission patterns.  (+info)

This paper points out that the predictability analysis of conventional time series may in general be invalid for long-range dependent (LRD) series since the conventional mean-square error (MSE) may generally not exist for predicting LRD series. To make the MSE of LRD series prediction exist, we introduce a generalized MSE. With that, the proof of the predictability of LRD series is presented in Hilbert space.

Injury to an immature permanent tooth may result in cessation of dentin deposition and root maturation leaving an open root apex and thin dentinal walls that are prone to fracture. Endodontic treatment is often complicated and protracted with an uncertain prognosis frequently resulting in pre-mature tooth loss. There are several advantages of promoting apexogenesis in immature teeth with open apices. It encourages a longer and thicker root to develop thus decreasing the propensity of long term root fracture. This case report highlights the role of Hertwig root sheath and dental papilla in continued root formation of immature permanent tooth, even diagnosed with necrotic pulp.

Regeneration as referred to in this protocol refers to the stimulation of continued root formation by the deposition of apical tissues subsequent to disinfection of a necrotic root canal and its contents and creation of a scaffold upon which cells can proliferate. While the proposed treatment protocol is currently being used in clinical practice and has been shown to be successful in case reports and case series, the nature of the proliferating apical tissues remains unknown. Thus, this study is uniquely positioned to address a critical gap in knowledge in the regeneration of a functional pulp-dentin complex. Moreover, results obtained from pediatric cases may well provide the essential foundation of knowledge for endodontists to apply this knowledge to the more difficult situation of regenerating the pulp-dentin complex of the full mature permanent tooth ...

This paper points out the significant genetic differences that are found throughout every population that must to be taken into account when extrapolating data from animals to humans, said Linda Birnbaum, Ph.D., director of NTP and NIEHS. The Diversity Outbred mouse is a useful model for predicting the range of response that might be observed in humans following exposure to a chemical.. Benzene was selected by NTP as a case study for testing the mouse model, because there is an abundance of animal and human toxicity data for comparison. Benzene can affect people differently, depending on the level and duration of exposure, making it important to accurately estimate the levels at which it may cause harm to the most susceptible individuals.. These genetically diverse mice provided a reproducible response to benzene exposure across two independently exposed groups, suggesting that each group of genetically unique mice demonstrated the same range of differential susceptibility, much like what ...

Downloadable! To evaluate whether transparency is beneficial, it is usual to assume that the central bank may choose one of two options, opacity versus truthful communication. However, the monetary policymaker may have incentives to misrepresent private information so as to reduce economic volatility by manipulating inflation expectations. Using a standard model, this paper points out the fact that if misrepresentation is included as a possible action there is no rational expectations equilibrium with inflation announcements. Therefore, even if transparency is preferred over secrecy the central bank cannot credibly commit to truth-telling, in contrast to what is commonly assumed in the literature on transparency

Deacon concludes these are common dynamic features that characterize morphodynamic phenomena, and make them an emergent level removed from subvenient homeodynamic processes whether at the thermodynamic or sub-atomic level. In each case he explains we find a tangled hierarchy of causality, where micro-configurational particularities can be amplified to determine macro-configurational regularities. Where these in turn further constrain and/or amplify subsequent cycles of this process, producing a compounding. The special reflexive regularities and the recurrent causal architecture of the cycles of interaction have come to overshadow the systems lower-order orthograde properties. These systems must be open to the flow of energy and/or components, which is what enables their growth and/or development, but they additionally include a higher order form of closure as well. Such flows propagate constraints inherited from past states of the system, which recurrently compound to further constrain the ...

Apical periodontitis, an acute or chronic inflamination around the apex of the tooth, is caused by bacteria in the root canal. In Sweden the dentists devote around 10X of their total time to treating this disease. The treatment usually requires 3 to 5 sessions. The treatment may fail in up to 25X of the cases. In the present study various treatment regimens were evaluated. One hundred and forty singlerooted teeth with apical periodontitis were treated. The importance of mechanical instrumentation, irrigating solutions and antibacterial dressings in eliminating bacteria from the infected root canals was studied using bacteriological techniques. The healing of the apical periodontitis after treatment was followed for 2 to 5 years on recall radiographs.. Bacteria were found in all 140 root canals at the beginning of the treatment. Most of these bacteria were anaerobes and they represented a restricted group of bacteria compared to the bacteria present at other sites in the oral cavity. Mechanical ...
The spread of caries in a tooth, if not arrested, will result in infection of the pulpal tissue and eventual pulpal necrosis i.e. the tooth dies off. This necrosed tissue may collect at the around the root of the tooth concerned. Inflammatory process will occur as the body responses to this collection. In essence the body tries to cure and protect oneself from the bad effect of this infection. However, in normal circumstances, the body usually is not able to wall-off the infection. Hence, there would be accumulation of acute inflammatory cells at the tip of a dead tooth. This is termed a periapical abscess by the dentist. Periapical abscess may arise as the initial periapical pathosis or from an acute exacerbation of a chronic periapical inflammatory lesion (phoenix abscess). It has to be reminded that the infection can happen in any part of the root i.e. not necessarily at the tip of the root.. Abscesses usually consists of a sea of polymorphonuclear leukocytes (aka white blood cells) often ...
The emergence of regenerative endodontic therapy (RET) represents a shift to a focus on revascularization, tissue regeneration and continued root development.10Lin LM, Kahler B.

Unlike extrinsic discolorations that occur on the surface, intrinsic discoloration is due to the presence of chromogenic (coloured) material within enamel or dentin, incorporated either during tooth developing (odontogenesis) or after eruption. This type of stain can be divided into 2 groups, preeruptive and posteruptive. The most common type of pre-eruptive staining is endemic fluorosis caused by excessive fluoride ingestion during tooth development. Post-eruptive stain usually associated with pulp problems such as pulp necrosis, or root canal material. Generally, intrinsic stain can be divided into:. Systemic causes are. ...
01 November 2012 In this paper on *Decent work, youth employment and migration in Asia*, Dr. Piyasiri Wickramasekara (former Senior Migration specialist of the ILO) discusses migration trends and issues concerning young people in Asia - a region hosting more than 60 per cent of worlds youth population and one third of the global number of young migrants. He first outlines some methodological issues in understanding the nexus between decent work, internal and international migration, and causes of youth migration pressures. Drawing on a variety of data sources, he highlights the profile of young Asian migrant workers, their working conditions and protection issues in major destination countries. The study finds that both adult and young female and male migrant workers face exploitation and poor working conditions in destination countries. The paper points out that there are few programmes or policies in origin or destination countries that directly address the specific issues faced by youth ...
2) However, we still need a theory of trademark meaning: example from the papers treatment of MICRO-THIN for condoms: all the results for micro thin condoms referred to the relevant plaintiffs mark, but as the paper points out, this could mean strength for condoms or it could just mean that the plaintiff is currently the only user of a not particularly distinctive term within that category-I think this is a more significant weakness than the paper acknowledges, because by entering micro thin condoms as the search term you have already taken the position of a consumer using the term to locate something, while what we should want to know is would a consumer use this term to identify source? The papers conclusion: when consumers search for MICROTHIN condoms, they are not simply looking for condoms that are extremely thin-they are generally looking for Kimono MicroThin condoms. But that when contains the assumption that drives the result. We dont know from these search results if the ...
They also provided a link to the Abortion Rights Coalition of Canadas policy paper wherein they call for the removal of registered charitable status of charities that do not support abortion. As the paper points out:. Almost all anti-abortion groups are religiously-based and motivated, because the anti-choice viewpoint is fundamentally a religious doctrine. Some counselling groups proselytize openly (often to unsuspecting and vulnerable clients), even though they obtained their charitable status on claims of being educational or engaged in research or family/crisis counselling. In fact, most Canadian anti-abortion counselling centres with charitable status are explicitly Christian.. Given the fact that the federal government is highly attuned to the demands of the pro-abortion community, this latest call for the removal of registered charitable status for religious communities that have an anti-abortion position has got to be taken seriously. This forms part of the reasoning which ...

  • CEM cement has been suggested as a suitable material in pulp capping of permanent molars with irreversible pulpitis. (
  • It is often the end result of many cases of dental trauma, caries and irreversible pulpitis. (
  • The pulp can respond (reversible pulpitis, irreversible pulpitis, partial necrosis, total necrosis) in a variety of ways to irritants. (
  • Inflammation of the dental pulp (pulpitis) generally presents with severe pain as toothache, which is commonly treated by either extracting the tooth or root canal treatment (RCT). (
  • Pulpitis or inflammation of the pulp may be acute or chronic, partial or total, and the pulp may be infected or sterile. (
  • 2. Chronic a. asymptomatic with pulp exposure b. hyperplastic pulpitis c. (
  • Reversible pulpitis is a mild to moderate inflammatory condition of the pulp caused by noxious stimuli in which the pulp is capable of returning to the uninflamed state following removal of the stimuli. (
  • Reversible pulpitis may be caused by any agent that is capable of injuring the pulp. (
  • When a carious lesion impinges on the dental pulp, pulpitis follows and, ultimately, necrosis of the pulp occurs. (
  • Dental caries erode the protective layers of the tooth (ie, enamel, dentin) and allow bacteria to invade the pulp, producing a pulpitis. (
  • Pulpitis can progress to necrosis, with bacterial invasion of the alveolar bone, causing an abscess. (
  • The main indications for RoCT are irreversible pulpitis and necrosis of the dental pulp caused by carious processes, tooth cracks or chips, or dental trauma. (
  • Hall technique should not be used when there are clinical or radiographic signs and symptoms of irreversible pulpitis or dental abscess. (
  • Eventually, the blood vessels and nerves within the dental pulp experience a chronic inflammation known as pulpitis . (
  • Damage to the enamel, either through trauma or from a developmental abnormality that allows bacteria to reach the pulp, will result in pulpitis and possibly pulp necrosis. (
  • However, more severe trauma will cause irreversible pulpitis, eventually leading to pulp necrosis. (
  • If there is generalized pulpitis, the effect can be an apparent accelerated aging of the entire tooth with an abnormally narrow root canal space and pulp chamber. (
  • Teeth with irreversible pulpitis or pulp necrosis require either endodontic treatment (root canal therapy) or extraction. (
  • Pulpitis is inflammation of the pulp, which occurs most commonly due to blunt trauma to a tooth. (
  • The colors seen with pulpitis-pink, purple, gray, brown-are due to trauma to blood vessels within the tooth, which results in leakage of red blood cells into the pulp chamber. (
  • Pulp treatment is unnecessary unless irreversible pulpitis or pulp necrosis develops. (
  • If you have dental pain, it might mean you have pulpitis. (
  • Among the dental diseases caused by dental caries, there are pulpitis and infected root canal. (
  • Regenerative endodontics provides the hope of converting the non-vital tooth into the vital state once again, focusing on substituting the traumatized and pathological pulp with functional pulp tissue. (
  • The branch of dentistry that deals with diseases and conditions of the tooth root, dental pulp, and surrounding tissue is called Endodontics. (
  • The potential for success of pulp regeneration after necrosis and infection would transform the practice of endodontics, even for mature teeth. (
  • So the aim of this study is to report that arsenical pastes are stil employed in endodontics, to highlight the potentially serious censequences of their use and to show positive effect of bephanthene in soft tissue necrosis belong to arsenic. (
  • Regenerative endodontics and pulp revascularization techniques appear as a dynamic and potentially ideal field for clinical therapy in teeth with incomplete root development. (
  • To understand the responses of the dental pulp to hypoxia is of high relevance for regenerative endodontics and dental traumatology. (
  • Endodontics Endodontics: basic is the branch of dentistry dealing with the diagnosis and treatment of diseases of the pulp. (
  • I Department of Endodontics, São Leopoldo Mandic Dental Research Center - Campinas - SP - Brazil. (
  • Up until the First World Conference on Endodontics was convened by Dr. Louis I. Grossman (Fig. 1 ) during the week of June 22, 1953 (Grossman 1953 ), multiple treatment parameters were being used daily by clinicians and different philosophies of treatment were being espoused in dental education around the world. (
  • Sequelae of a necrotic pulp include acute apical periodontitis, dental abscess or radicular cyst and discolouration of the tooth. (
  • A striking feature was invasion of dentinal tubules with Streptococcus mitis and microabcesses that originated in pulp horns and progressed to pulp necrosis and periodontitis. (
  • This case series reports the outcomes of 8 patients (ages 9-14 years) who presented with 9 immature permanent teeth with pulpal necrosis and apical periodontitis. (
  • Periodontitis associated with endodontic lesions involves a communication between the pulp and periodontal tissues. (
  • Three immature permanent teeth with pulp necrosis and apical periodontitis were treated with regenerative endodontic therapy (RET), which included root canal disinfection with sodium hypochlorite irrigation, intra-canal medication with calcium hydroxide paste, 17% EDTA rinse, induction of periapical bleeding into the canal, collagen matrix and MTA coronal seal, and composite resin restoration of access cavities. (
  • Contrary to Indirect Pulp Capping (IPC), in this technique only the central infected part of the caries is removed in first visit and the rest of the caries will be lined by a suitable material to suppress the remained cariogenic biomass and seal the cavity. (
  • Two weeks after the direct capping of a calcium hydroxide (Dycal), within the pulp calciotraumatic lines (CTL) (arrows), separate the dentin formed before the preparation of the cavity from the reactionary dentin (RD). In the left part, the Ca(OH) 2 has induced the formation of a reparative bridge in the isthmus separating the central from the distal pulp horns of 6-week-old rat's maxillary molar. (
  • The iatrogenic injury that happened during cavity preparation is the common cause of the pulp irritation. (
  • Iatrogenic dental procedures (wedging of teeth , cavity or crown preparation. (
  • Lesions of endodontic origin are associated with bacterial contamination and necrosis of the dental pulp, which typically progress through four stages: (1) exposure of the dental pulp to the oral cavity with subsequent bacterial colonization, (2) inflammation and necrosis of the dental pulp, (3) the development of inflammation in the periapical area, and (4) periapical resorption of bone and formation of granulomas or cysts. (
  • As a temporary measure, fill a sugarless gum in the cavity or over the counter dental cements. (
  • Throughout life, the pulp produces dentin on the inside surface of the pulp cavity, resulting in a constantly decreasing cross-sectional width of the pulp chamber in the crown and root canal in the root of the tooth. (
  • Generally, when evaluating a tooth with endodontic and/or periapical disease, the focus should be on structural defects at its crown and root apex, the width of its pulp cavity, and the appearance of the periapical tissues. (
  • A study sought to determine whether oral cavity cancers occurred more commonly at sites of dental trauma. (
  • The study concluded that oral cavity cancers occur predominantly at sites of potential dental and denture trauma, especially in nonsmokers without other risk factors. (
  • In case of a healthy tooth, a central cavity (root canal) runs in the longitudinal direction within the tooth, and the root canal opens a fine hole (apical foramen) at the tip of the tooth, which receives blood through this fine hole, and nourishes the nerve fiber (dental pulp). (
  • Non-vital teeth with an open end are routinely treated in this way at Liverpool Dental Hospital. (
  • Prevalence de microorganisms in root canals of human deciduous teeth with necrotic pulp and chronic periapical lesions. (
  • Dental trauma refers to trauma (injury) to the teeth and/or periodontium (gums, periodontal ligament , alveolar bone ), and nearby soft tissues such as the lips, tongue, etc. (
  • They extirpated the pulps and instrumented the root canals of the teeth of seven dogs. (
  • The pulp may also become exposed or nearly exposed by pathologic wear of the teeth from either abrasion or attrition if secondary dentin is not deposited rapidly enough. (
  • Laser radiation sufficient to cause cavitation in teeth also causes severe degenerative changes in the pulp. (
  • Dental caries, a bacterial disease of teeth characterized by destruction of enamel and dentine, is often the underlying cause of dental pain. (
  • They demonstrated regeneration of dental pulp containing an odontoblast layer, blood vessels, and nerves in the implanted teeth and rescue of sensation to stimuli such as temperature. (
  • Pulp necrosis arrests root development in injured immature permanent teeth, which may result in tooth loss. (
  • We show that implantation of autologous tooth stem cells from deciduous teeth regenerated dental pulp with an odontoblast layer, blood vessels, and nerves in two animal models. (
  • Pioneering oral epidemiologists developed an index to measure the prevalence of dental caries using the number of decayed, missing, or filled teeth (DMFT) or decayed, missing, or filled tooth surfaces (DMFS) (5) rather than merely presence of dental caries, in part because nearly all persons in most age groups in the United States had evidence of the disease. (
  • Soon after establishing his dental practice in Colorado Springs, Colorado, in 1901, Dr. Frederick S. McKay noted an unusual permanent stain or 'mottled enamel' (termed 'Colorado brown stain' by area residents) on the teeth of many of his patients (6). (
  • McKay also observed that teeth affected by this condition seemed less susceptible to dental caries (7). (
  • Dental abscess is rare in infants because abscesses do not form until teeth erupt. (
  • Dental pulp regeneration after pulp necrosis in immature teeth represents a major departure from traditional endodontic therapy of these conditions. (

  • Reassess the patient in 7-14 days, at which time pulp extirpation should be considered for incisors with closed apices, and the splint should be removed unless injuries to other teeth warrant a longer splinting duration. (
  • It is also important that the dental hygienist review brushing instructions with the parents to make sure the teeth are healthy and clean. (
  • They were thoroughly examined for injury/fracture to facial region as well as for dental injuries (teeth). (
  • Traumatic dental injuries (TDIs) such as subluxations of primary teeth can have significant consequences on their developing successors. (
  • A dental avulsion occur when teeth are dislodged entirely from the socket. (
  • Whenever treatment failed and teeth were removed they were examined at the Department of Oral Pathology at the Dental School which had strong ties to the University Hospital (the senior author having a dual appointment at both institutions). (
  • In addition to colonizing the teeth in significant numbers, it is not unusual for S. mutans to gain access to the bloodstream during dental procedures ( 16 , 21 , 26 ). (
  • A 32 years old, male patient had suffered subluxation of teeth 12 and 13 and coronal fracture involving enamel and dentin, as well as pulp exposition, of tooth 14 because of a motorcycle accident. (
  • The man was given dental assistance and a semi-rigid splinting of teeth numbers 12 and 13 was carried out followed by the root canal treatment in a single visit on tooth no. 14. (
  • At 30-day follow-up pulp necrosis was detected in teeth 12 and 13 and the root canal treatment was implemented. (
  • Early transplantation of human immature dental pulp stem cells from baby teeth to golden retriever muscular dystrophy (GRMD) dogs: Local or systemic? (
  • Dental stem cells are isolated and characterized as follows: dental pulp stem cells (DPSCs) from pulp of permanent teeth, immature dental stem cells from primary teeth, periodontal ligament stem cells (PDLSCs), and stem cells from apical papilla (SCAP), etc. (
  • The Hall Technique has been included in a guideline of the Scottish Dental Clinical Effectiveness Programme (SDCEP) [9] and has helped to drive change in how dentists manage decay in primary teeth from the traditional invasive surgical approach to the less-invasive biological management of decay. (
  • Introduction: Immature permanent teeth that evolve to pulp necrosis represent a challenge for endodontic treatment. (
  • Objective: To review the literature on pulpal revascularization techniques in the treatment of teeth with absence of pulp vitality with immature root apex. (
  • Contra-indicated in fractured deciduous teeth Dental fracture . (
  • Contra-indicated in teeth with vertical root fractures Dental trauma: root fracture . (
  • To describe the causes of discolored non-vital teeth, - To explain the protocol of the different bleaching procedures and the agents used for, - To report different clinical cases of discolored non-vital teeth treated in our service of Dental Medicine with internal bleaching procedures. (
  • A landmark study 2 published in 2001 showed that, of 64 discolored teeth that were explored via pulpotomy, 59 had gross evidence of partial or complete pulp necrosis (92 percent). (
  • Forty-two percent of discolored teeth evaluated radiographically in the study had no radiographic evidence of endodontic disease, suggesting that radiographic signs lag behind pulp inflammation and necrosis. (
  • Dental trauma includes concussion, subluxation and dislocation of teeth, and fracture of teeth and maxillofacial bone, in addition to soft tissue injury that may cause ecchymosis, hematoma and laceration or abrasion. (
  • Fourteen teeth from the experimental group showed lack of pulp sensitivity, whereas only one tooth from the control group showed negative pulp sensitivity. (
  • Studies have been conducted on the effects of applying orthodontic forces to teeth in order to assess the effects of these forces on the dental pulp 1,5,9,13 . (
  • Orthodontic forces may impede pulp circulation, causing vascular congestion and pulp edema, leading to pulp damage 14,27 and even necrosis in teeth submitted to traction [29]. (
  • Studies conducted in 1965 found similar characteristics between the pulp of teeth submitted to orthodontic movement and that of teeth with periodontal involvement. (
  • A radiographic analysis of teeth submitted to induced orthodontic movement showed that they seemed to age more rapidly than those that were not submitted to this procedure, demonstrating that pulp atrophy resulting from the obliteration of the root canal by reparative dentin may be involved 24 . (
  • Irreversible damage to teeth may vary from apical resorption to pulp involvement, resulting in ischemia and necrosis 1 . (
  • However, it is known that pulp necrosis caused by induced tooth movement also depends on the stage of dental root development, and that teeth with an open apex have a better prognosis 10 . (
  • The other group of 4 teeth had no evidence of any residual vital pulp tissue. (
  • We believe that this enduring approach will indeed facilitate regenerative endodontic procedures (REP), as a treatment of choice for immature teeth with chronic inflammatory and necrosis conditions. (
  • Pulp canal obliteration and root resorption were found in 2.8% and 2.3% of teeth with TDI, respectively. (
  • CONCLUSIONS: Occurrence of different pulp sequelae among teeth affected with TDI was low. (
  • Commonly occurring canine dental and oral lesions include: variations in number of teeth and roots, periodontal disease, endodontic disease, dental caries, dental attrition/abrasion, discolored teeth and oral masses (benign and malignant). (
  • While baby teeth may not seem important enough for a dental procedure like this, there are valid reasons for pulpectomy. (
  • Tooth extraction is done using manual dental instruments, to remove nonviable, nonsalvageable teeth. (
  • citation needed] Tests for a necrotic pulp include: vitality testing using a thermal test or an electric pulp tester. (
  • Microorganisms isolated from root canals presenting necrotic pulp and their drug susceptibility in vitro. (
  • A necrotic pulp discontinues its normal dentin production, and thus it falls behind that of a normally maturing tooth adjacent to it or on the contralateral side. (
  • Figure 3: Exploratory pulpectomy shows a partially necrotic pulp with an abnormal brown color to a portion of the pulp and lack of bleeding. (
  • Dotted lines indicate the drilled dentin with clear pulp exposure, arrows show cellular debris, and squares indicate the area shown at high magnification in (C) . Arrowheads indicate CD146 + cells. (
  • Beneath a calciotraumatic line, a thin layer identified as reactionary dentin underlines the periphery of the pulp chamber. (
  • One week after the pulp exposure, dentin debris is pushed in the pulp exposure. (
  • 6 There exists a rich cocktail of bioactive molecules in dentin and pulp capable of giving the signaling events involved in dentin and pulp regeneration. (
  • Unchecked, the bacteria then may penetrate the underlying dentin and progress into the soft pulp tissue. (
  • Current and future strategies for disinfecting the pulp space with minimal disruption of the necessary biological factors from dentin, the progenitor cells in periapical vital tissues, and the vascularity are discussed. (

  • Another natural issue of concern is that, as we age, the size or volume of the pulp changes because the continued formation of secondary dentin throughout the life of the tooth gradually reduces the size of the pulp chamber and the canals in the roots. (
  • The pulp is protected from bacteria by the impervious enamel covering the dentin of the crown. (
  • Because dental pulp has no collateral circulation, injuries heal less readily, and extravasated blood remains in the dentin, where it deteriorates rather than being removed. (
  • Conversely, an inflamed pulp produces dentin at an accelerated rate. (
  • Uncomplicated crown fractures may involve enamel and dentin without pulp exposure. (
  • My lab focuses on translational research for innovative therapeutic scaffolds using 3D Bioprinting technology to construct scaffolds/ECM that will facilitate regeneration of the pulp-dentin complex, resulting in formation of new dentin and promote a positive long-term prognosis for the tooth. (
  • At present the practice is to remove the inflamed dental pulp under local anasthesia (extirpation of the pulp), or in case of an infected root canal, to remove the infected dentin, then clean, disinfect and fill the hollowed root canal compact with a filling material (canal filling). (
  • The surfaces of the root canal after extirpation of the pulp and the infected root canal are not only smooth but have the remaining protein, and particularly in case of the infected root canal, there are various impurities such as microorganisms and pus, and the surface of the root canal itself, being infected by microorganisms, is softened (soft dentin) to form a lesion deeply infected by microorganisms.
