X trisomy in an infertile bitch: cytogenetic, anatomic, and histologic studies. (1/197)

Three copies of the X chromosome were identified in a 5-year-old mixed breed infertile bitch. One year after the cytogenetic examination, the bitch died due to gastritis hemorrhagica, an inflammation of the mucus coat of the stomach. Dental studies showed congenital lack of some premolar and molar teeth. Ovaries were of normal shape and size. Also, histologic sections of the ovaries revealed their normal structure, with two corpora lutea and primary follicles. Phenotypic effects of X trisomy are discussed.  (+info)

Persistence of deciduous molars in subjects with agenesis of the second premolars. (2/197)

The purpose of the present study was to investigate persistent primary second molars in a group of young people in their late twenties with agenesis of one or two second premolars. In 1982-83 it was decided, in connection with the orthodontic evaluation of 25 patients, to allow 35 primary molars (one or two in each patient) to remain in situ. All patients had mixed dentitions and agenesis of one or two premolars. The primary teeth were generally in good condition, although root resorption and infra-occlusion (compensated by occlusal composite onlays) occurred. In 1997, 18 of the 25 patients with a total of 26 retained primary molars were reexamined, comprising a clinical examination for exfoliation, extraction, loosening, and ankylosis, and a radiographic examination for root resorption, tooth morphology (crown and root), and alveolar bone contour. The examination showed that the degree of root resorption was unaltered in 20 of the 26 primary molars. In the permanent dentitions, where these primary molars persisted, there were no morphological deviations. Three of the six remaining primary molars had been extracted and three showed extensive resorption. In three of the 26 primary molars the infra-occlusion had worsened. The present study shows that persistence of primary second molars in subjects with agenesis of one or two premolars, and normal morphology of the permanent dentition can be an acceptable, semi-permanent solution for the patient. Whether this could also be an acceptable long-term solution will be shown by follow-up studies.  (+info)

The long-term survival of lower second primary molars in subjects with agenesis of the premolars. (3/197)

This study investigated 41 subjects, 13 male and 28 female, with agenesis of one or both lower second premolars, and with retained lower second primary molars. Intra-oral radiographs of 59 primary teeth were examined to judge the resorption of the mesial and distal roots, and were measured to record infra-occlusion of the primary teeth and tipping of the adjacent permanent teeth. The study commenced at 11-12 years of age. The mean age at the last measurement was 20 years 6 months (SD 3.62, range 13.6-31.8 years). During the observation period, only two of the 59 primary teeth were exfoliated. Five were extracted, two of which were replaced by upper third molar transplants. Beyond the age of 20 years no teeth were lost. Root resorption varied widely between individuals, but was slow. There was no typical pattern for development of infra-occlusion. Mean infra-occlusion was 0.47 mm (SD 1.13) at 11-12 years, increasing by less than 1.0 to 1.43 mm (SD 1.13) at age 17-18 years. At age 19-20 years, 55 per cent of teeth showed infra-occlusion between 0.5 and 4.5 mm, but 45 per cent showed no infra-occlusion. The space between the first molar and first premolar was a mean of 10.35 mm (SD 0.76) at age 10-12 years compared with the mean width of the second primary molar of 10.53 mm (SD 0.51). The space reduced by less than 0.5 mm to 9.95 mm (SD 1.50) at age 17-18 years. If primary molars are present at 20 years of age they appear to have a good prognosis for long-term survival.  (+info)

An analysis of the skeletal relationships in a group of young people with hypodontia. (4/197)

The objective of this investigation was to examine the dentofacial features of a group of patients with hypodontia, in particular assessing whether cephalometric analysis confirmed the clinical assumption of a reduced lower face height, and to determine the relationship of these facial features with different numbers of missing teeth. It took the form of a cephalometric study, undertaken in a dedicated Dental Hospital clinic for patients with hypodontia. The study group comprised 59 patients seen on the Hypodontia Clinic: 32 females, 27 males, mean age 13.1+/-3.1 years (range 6-23 years). The average number of missing teeth was 7 (SD 5), ranging from 1 to 21. The mean SNA, SNB, and MMA angles were within normal limits, but there was a statistically significant reduction in the MMA when more than one tooth type was missing (P = 0.007) and the ANB angle decreased as the number of missing tooth types increased (P = 0.034). The mean values for the whole sample were within the normal range and did not demonstrate any feature specific to the group, but patients with more severe hypodontia showed tendencies to a Class III skeletal relationship and a reduced maxillary-mandibular planes angle.  (+info)

Congenitally missing maxillary lateral incisors and orthodontic treatment considerations for the single-tooth implant. (5/197)

Implant restorations have become a primary treatment option for the replacement of congenitally missing lateral incisors. The central incisor and canine often erupt in less than optimal positions adjacent to the edentulous lateral incisor space, and therefore preprosthetic orthodontic treatment is frequently required. Derotation of the central incisor and canine, space closure and correction of root proximities may be required to create appropriate space in which to place the implant and achieve an esthetic restoration. This paper discusses aspects of preprosthetic orthodontic diagnosis and treatment that need to be considered with implant restorations.  (+info)

Survey of dental treatments for pediatric patients referred to the pediatric dental clinic of a dental school hospital. (6/197)

This survey was conducted to clarify which dental treatments in children are regarded as difficult by general dentistry practitioners. The subjects were 615 children who first visited Tokyo Dental College Chiba Hospital from January 1995 to August 1999 with reference letters. There were 615 children in the study; 571 (92.8%) came from Chiba City where our hospital is located and the 11 regions surrounding Chiba City. The prime reasons for referral in the order of frequency were treatments of dental caries, malalignment/malocclusion, traumatized teeth, supernumerary teeth, retarded eruption/impacted teeth, abnormal direction of erupted teeth, congenitally missing teeth, prolonged retention of deciduous teeth, and abnormal frenulum. Patients with dental caries or traumatized teeth in the deciduous dentition period and those with malalignment/malocclusion, supernumerary teeth, or retarded eruption/impacted teeth in the mixed dentition period were often referred to medical organizations specializing in pediatric dentistry because of the difficulties in controlling the patients' behavior and in providing adequate treatment. The information about pediatric dental treatments considered difficult by general dentists revealed by this survey appears to be useful and needs to be incorporated in the programs for clinical training of undergraduate students and education of postgraduate students.  (+info)

The congenitally missing upper lateral incisor. A retrospective study of orthodontic space closure versus restorative treatment. (7/197)

Orthodontic treatment for patients with uni- or bilateral congenitally missing lateral incisors is a challenge to effective treatment planning. The two major alternatives, orthodontic space closure or space opening for prosthetic replacements, can both compromise aesthetics, periodontal health, and function. The aim of this retrospective study was to examine treated patients who had congenitally missing lateral incisors and to compare their opinion of the aesthetic result with the dentists' opinions of occlusal function and periodontal health. In this sample, 50 patients were identified. Thirty had been treated with orthodontic space closure, and 20 by space opening and a prosthesis (porcelain bonded to gold and resin bonded bridges). The patient's opinion of the aesthetic result was evaluated using the Eastman Esthetic Index questionnaire and during a structured interview. The functional status, dental contact patterns, periodontal condition, and quality of the prosthetic replacement was evaluated. In general, subjects treated with orthodontic space closure were more satisfied with the appearance of their teeth than those who had a prosthesis. No significant differences in the prevalence of signs and symptoms of temporomandibular dysfunction (TMD) were found. However, patients with prosthetic replacements had impaired periodontal health with accumulation of plaque and gingivitis. The conclusion of this study is that orthodontic space closure produces results that are well accepted by patients, does not impair temporomandibular joint (TMJ) function, and encourages periodontal health in comparison with prosthetic replacements.  (+info)

Face, palate, and craniofacial morphology in patients with a solitary median maxillary central incisor. (8/197)

The occurrence of a solitary median maxillary central incisor (SMMCI) is a very rare condition and might be a sign of a mild degree of holoprosencephaly. In this investigation, material from 10 patients, nine girls and one boy with a SMMCI (8-17 years of age) registered in orthodontic clinics was examined. The purpose was to evaluate the clinical characteristics and craniofacial morphology in this group of patients. Oral photographs, study casts, profile radiographs, and orthopantomograms were analysed. The study showed that this group of SMMCI patients were characterized by an indistinct philtrum, an arch-shaped upper lip, absence of the fraenulum of the upper lip, a complete or incomplete mid-palatal ridge, a SMMCI, and nasal obstruction or septum deviation. The craniofacial morphology of the nine girls, compared with normal standards for girls showed a short anterior cranial base, a short, retrognathic and posteriorly inclined maxilla, and a retrognathic and posteriorly inclined mandible. Furthermore, the sella turcica had a deviant morphology in five of the 10 subjects. The results indicate that the presence of a SMMCI should not be considered as a simple dental anomaly, since it may be associated with other clinical characteristics and more complex craniofacial malformations. It is therefore suggested that the SMMCI condition in future studies is classified according to clinical symptoms and craniofacial morphology.  (+info)

Partial anodontia. Congenitally missing teeth are more common among individuals with Down syndrome (50%) when compared to the general population (2%), though the distribution of missing teeth is similar in both populations.22 Genetic modes of transmission are responsible for this condition. A relationship between partial anodontia and other ectodermal defects (mucous membrane, hair, skin) has been suggested.19 Further research indicated that this Trisomic insult will greatly increase the susceptibility of the host to partial anodontia, while not affecting specific tooth buds.22 The most frequently missing teeth in descending order are third molars, second bicuspids, lateral incisors, and mandibular incisors. The only teeth not missing are first molars.22 Sometimes the primary tooth will not be resorbed or will be resorbed so slowly that it can be retained well into adulthood.24 Treatment decisions should be made after reviewing the radiographs with concern for space maintenance. In the general ...

The cause of isolated missing teeth remains unclear, but the condition is believed to be associated with genetic or environmental factors during dental development. Missing teeth have been reported in association with increased maternal age, low birth weight, multiple births and rubella virus infection during embryonic life.[citation needed] In a recent study assessing environmental risk factors for hypodontia, it was established that maternal smoking does play a causative role in Hypodontia. Passive smoking and caffeine were also assessed but showed no statistical significance.[7] There is a possible correlation between tooth agenesis and innervation.[8][9][10][11][12] A relationship was also postulated between abnormalities of the brainstem and the presence of agenesis.[13] Hypodontia is often familial, and can also be associated with genetic disorders such as ectodermal dysplasia or Down syndrome. Hypodontia can also be seen in people with cleft lip and palate. Among the possible causes are ...
Missing teeth in early childhood can result in abnormal facial morphology with a narrow upper airway.6 Dental agenesis, which is the manifestation of missing permanent teeth, is the most prevalent craniofacial anomaly in humans.7 The potential association between dental agenesis or early dental extractions and the presence of OSA has been investigated.6 OSA causes breathing to repeatedly stop and start during sleep; this type of apnea occurs when the throat muscles intermittently relax and block the airway. A noticeable sign of OSA is snoring. OSA is characterized by upper airway collapsibility, repetitive pharyngeal collapse during sleep. Therefore, one variable used in describing the mechanics of the upper airway is to measure its propensity for collapse.8. A study was conducted of 31 children with dental agenesis and 11 children with early dental extractions who had at least two permanent teeth missing.6 All children with missing teeth had identifiable clinical signs of OSA. There was a ...

A specific form of hypodontia with an autosomal recessive mode of inheritance characterized by missing primary and permanent incisors and an increased inclination to eczema and asthma has been found in Finland (Pirinen et al, 2001) and apparently also in other countries (Fried, 1977; Akyuz et al, 1993; Lyngstadaas et al, 1996). RIH patients lack several lower incisors and upper permanent lateral incisors. In addition, some other permanent teeth can be missing. Half the patients have a corresponding primary tooth either missing or peg-shaped. Taurodontism of the molars is noted in more than half the patients. A large proportion of the patients (62%) report allergies manifesting as atopic skin (52%), and asthma (43%). Minor dental anomalies are seen in their parents and siblings in the form of missing and/or peg-shaped upper lateral incisors and missing third molar(s). The proportion of atopic diseases, both in the patients and their family members exceeds reported population prevalences. In a ...
We recently identified a frame-shift mutation in the PAX9 gene as the underlying cause for hypodontia involving permanent molar teeth segregating in an autosomal dominant pattern in a single large family (Stockton et al. 2000). Here we report a small nuclear family in which a father and his daughter are affected with severe hypodontia, involving agenesis of all primary and permanent molars, evidently caused by deletion of the entire PAX9 gene. Hemizygosity at the PAX9 locus in the two affected individuals was initially discovered when an informative single nucleotide polymorphism, identified while sequencing the gene for mutations, appeared to demonstrate non-Mendelian inheritance. Fluorescence in situ hybridization (FISH) analysis with a cosmid containing the PAX9 gene yielded a signal on only one chromosome 14 homologue and confirmed the presence of a deletion encompassing the PAX9 locus. Analysis of microsatellite loci in the vicinity of PAX9 delineated one breakpoint of the deletion. These ...
The purpose of this project is to examine whether the risk of developing ovarian cancer is increased in Danish women with congenital missing teeth as a result of their failure to develop (hypodontia). Should this prove to be the case, these women could be offered regular clinical controls and prophylactic removal of their ovaries when menopause enters and the ovaries are no longer functional (producing hormones).. If there is a connection between congenital hypodontia and the development of different types of cancer, the investigators will perform a genetic screening in families with increased risk of cancer and hypodontia for changes in relevant genes, based on the current literature. The investigators hereby search for new genes, which in a changed form leads to an increased risk of cancer and thereby enables us to perform genetic screening in risk families. ...

Maxillary lateral incisor agenesis is relatively common in orthodontic offices and requires multidisciplinary action. While these cases are usually treated with a lateral incisor implant, a resin-modified bridge (RMB), or orthodontic space closure, little attention has been placed in the literature on comparing these three treatments in a posttreatment esthetic evaluation. This study asked orthodontists, prosthodontists, and general dentists to evaluate the final aesthetic outcomes of these treatment options. Using anterior intraoral photographs, all dentists were asked to rate the esthetics of differently treated missing lateral incisors, to identify which treatment was rendered, and develop a treatment plan a lateral incisor agenesis case. Results showed that implants and RMBs separately were esthetically rated the same for all three doctor groups, while space closure was ranked less esthetic by prosthodontists than by orthodontists or general dentists. All doctor groups could distinguish ...
Tooth agenesis can involve one or more congenitally missing teeth (CMT) and is the most common congenital dental anomalies in humans. Tooth agenesis and reduction of mesiodistal tooth width are reportedly associated, suggesting that the pathogenesis of the two conditions is related. The current study analyzed the frequency of tooth agenesis and mesiodistal tooth width in cases of hypodontia (1-5 CMT) and oligodontia (≥ 6 CMT) in Japanese patients based on the hypothesis that reductions in mesiodistal tooth width are more frequently associated with oligodontia than hypodontia. Japanese patients with tooth agenesis were divided into hypodontia cases (60 female and 25 male, mean age 19.6 years, mean CMT number 1.31 ± 1.65) and oligodontia cases (26 female and 25 male, mean age 14.6 years, mean CMT number 8.07 ± 2.39). Controls included patients with a skeletal class I relationship and no CMT (female and 60 male, mean age 20.8 years). Dental casts and orthopantomograms were used to analyze the CMT

DISCUSSION. A case of CHH is presented here, wherein a 20-year-old female has missing mandibular central incisors, maxillary second molars, and all the third molars. In addition, she had a malformed supernumerary tooth in the mandibular left anterior region. After a thorough literature search, the rarity of such an occurrence prompted the authors to present this case.. When the tooth or teeth are clinically and radiographically absent and there is no history of extraction or traumatic avulsion of teeth, it is termed as agenesis or hypodontia. Literature search reveals that 15% of missing teeth are lower second premolars, 19% upper second premolars, 29% upper lateral incisors, 11% lower first premolars, 3% lower central incisor, and 1% are lower lateral incisor. Hypodontia of second molars and canine is rare (0.7% of missing teeth). Furthermore, 71% of individuals with hypodontia of some other teeth also lacked third molars.7 In the case presented here, bilateral maxillary second molar agenesis ...

The congenital absence of teeth, commonly referred to as hypodontia or tooth agenesis, is a common developmental anomaly of human dentition that affects approximately 20% of the population. Although new genetic and molecular approaches in humans and mice have increased our understanding of the molecules that control tooth patterning (number, position, shape and size), the precise nature of the genes involved in hypodontia in humans is poorly understood. Hence, understanding the molecular basis for missing teeth is an issue of paramount importance that is both timely and significant to the practice of dentistry. So far, only two genes have been associated with non-syndromic familial tooth agenesis: MSX1 and PAX9. Substitution mutations in the homeodomain region of MSX1 were linked to premolar agenesis while an insertion mutation in the paired box domain of PAX9 was shown to be responsible for molar oligodontia.. The long-term goals of this research are to elucidate the molecular pathology of ...

Recent advances in dental adhesives allow reattachment of fragments in subgingivally fractured teeth. However, success will depend on the skill of the clinician and care by the patient.
The aim of this study was to investigate the prevalence of tooth agenesis, microdontia, and tooth malformation among non-syndromic oral cleft patients and their potential association with cleft type and gender. Intraoral records and radiographs of 154 patients (97 males and 57 females) were examined. The variables assessed were tooth agenesis, microdontia, dental malformations, and cleft types. The statistics included chi-square and Fishers exact tests as well as logistic regression to assess any mutual effects of gender and cleft type on the dental variables. Tooth agenesis occurred in 50% of the sample and microdontia in 18%. Non-statistically significant odds ratios for the association of gender and cleft type with tooth agenesis were obtained. Tooth agenesis was substantially higher at the unilateral right CL + P and the bilateral CL + P in quadrant 1 and at the unilateral left CL + P and bilateral CL + P in quadrant 2. It was also higher, at the isolated cleft palate (CP) in quadrants 3 and 4.

A suite of dental characteristics displayed by the type specimen are all that distinguishes P. piveteaui from the other members of the genus. This mandibular fragment exhibits a distinct molar morphotype containing a very small and tapered M3 when compared to the distally narrowing M2 (Hartwig). The teeth are very small, but in the range of P. antiquus. Two upper teeth are known from the species, a P4 and M3. When the P4 is compared to an isolated P4 from Poland of either P. antiquus or P. platyodon, it is unconfirmed as to which species the isolated P4 belongs to, that of P. piveteaui is much smaller and broader (Hartwig).. ...

Aims: To assess the rate of tooth movement, anchorage loss, root resorption, and alkaline phosphatase (ALP) activity in the gingival crevicular fluid (GCF) as a marker for bone remodeling during orthodontic space closure using two different mechanisms. Methods: Space closure was completed in 20 patients with extraction of all 4 premolars. Lateral cephalograms and radio visiographs taken before (T1) and after (T2) space closure were assessed for anchorage loss and root resorption. Alkaline phosphatase levels were measured in 10 patients, which were divided into two groups of five each. Spaces were closed with a screw device in the first group and with active tie-backs in the second. Gingival crevicular fluid samples, collected at intervals, were assayed for alkaline phosphatase spectrophotometrically in each patient. Results: The mean rate of tooth movement was 1.32 0.22 mm/month. The mean amount of anchorage loss in the maxilla and mandible was 1.23 0.60 mm and 1.08 0.65 mm, respectively. Sixty ...
TY - JOUR. T1 - Missing teeth and pediatric obstructive sleep apnea. AU - Guilleminault, Christian. AU - Abad, Vivien C.. AU - Chiu, Hsiao Yean. AU - Peters, Brandon. AU - Quo, Stacey. PY - 2016. Y1 - 2016. N2 - Background: Missing teeth in early childhood can result in abnormal facial morphology with narrow upper airway. The potential association between dental agenesis or early dental extractions and the presence of obstructive sleep apnea (OSA) was investigated. Methods: We reviewed clinical data, results of polysomnographic sleep studies, and orthodontic imaging studies of children with dental agenesis (n = 32) or early extraction of permanent teeth (n = 11) seen during the past 5 years and compared their findings to those of age-, gender-, and body mass index-matched children with normal teeth development but tonsilloadenoid (T&A) hypertrophy and symptoms of OSA (n = 64). Results: The 31 children with dental agenesis and 11 children with early dental extractions had at least 2 permanent ...
Tooth agenesis is one of predominant developmental anomalies in humans, usually affecting the permanent dentition generated by sequential tooth formation, and in most cases caused by mutations perturbing epithelial Wnt/β-catenin signaling. Also loss-of-function mutations in the Wnt feedback inhibitor AXIN2 lead to human tooth agenesis. We investigated the functions of Wnt/β-catenin signaling during sequential formation of molar teeth using mouse models. Continuous initiation of new teeth, observed after genetic activation of Wnt/β-catenin signaling in the oral epithelium, was accompanied by enhanced expression of Wnt antagonists and a downregulation of Wnt/β-catenin signaling in the dental mesenchyme. Genetic and pharmacological activation of mesenchymal Wnt/β-catenin signaling negatively regulated sequential tooth formation, an effect partly mediated by Bmp4. Runx2, a gene whose loss-of-function mutations result in sequential formation of supernumerary teeth in the human cleidocranial ...
Abnormalities in size of teeth and number of teeth are occasionally recorded in clinical cases. True generalized microdontia is rare case in which all the teeth are smaller than normal. Mesiodens is commonly located in maxilary central incisor region and uncommon in the mandible. In the present case a 12 year-old boy was healthy; normal in appearance and the medical history was noncontributory. The patient was examined and found to have permanent teeth that were smaller than those of the average adult teeth. The true generalized microdontia was accompanied by mandibular mesiodens. This is a unique case report of non-syndromic association of mandibular hyperdontia with true generalized microdontia.
Most childrens permanent teeth erupt on a fairly predictable schedule. Sometimes, though, one or more teeth might not develop as they should - or at all.. These absent teeth pose functional problems for chewing and hygiene, which can affect long-term dental health. But they can also have a disruptive effect on an otherwise attractive smile if the missing teeth are the upper lateral incisors in the most visible part of the smile.. You normally find this pair of teeth on either side of the upper central incisors (the two front-most teeth). On the other side of the lateral incisors are the canine or eye teeth, known for their pointed appearance. Without the lateral incisors, the canines tend to drift into the space next to the central incisors. This can produce an odd appearance even a layperson will notice: only four teeth where there should be six!. Its possible to correct this abnormality, but it will take time and expense. The first step is usually to move the teeth in the upper jaw with ...

Certain clinical features in men and women are highly associated with genetic causes of KS. Synkinesia (KAL1), dental agenesis (FGF8/FGFR1), digital bony abnormalities (FGF8/FGFR1), and hearing loss (CHD7) can be useful for prioritizing genetic screening.
A number of our teeth are not genetically stable. By that, I mean that we have a high likelihood to from birth be missing teeth, have deformed teeth, or have extra teeth. The third molars are often completely or partially absent. The upper lateral incisors (teeth on either side of the middle top teeth) are often missing or mis-shapen (Google peg laterals for more). Even the two center upper teeth sometimes duplicate (Google mesiodens for more on that ...

Cutaneous LP is a self-limiting condition. It usually resolves within 6 to 12 months. Oral LP is a non infectious, chronic inflammatory condition that involves the oral mucosa and may be accompanied by skin lesions. The etiology of oral LP are unknown. It is not clear whether the mechanisms causing isolated oral LP are different from those causing oral LP with cutaneous LP. An immune-mediated mechanism where basal keratinocytes are being targeted as foreign antigens by activated T cells, especially CD8+ T cells, has been proposed.[43] Upregulation of intercellular adhesion molecule-1 (ICAM-1) and cytokines associated with T-helper 1 immune response, may also pay an important role in the pathogenesis of lichen planus. Stress is thought to play a role in the pathogenesis of oral LP. Patients with anxiety and depression are reported more commonly with oral LP if compared to normal healthy individuals.[44][45] Some studies have indicated that stressful events can induce LP lesions in otherwise ...
Aphthous affectations" and "aphthous ulcerations" of the mouth are mentioned several times in the treatise "Of the Epidemics" (part of the Hippocratic corpus, in the 4th century BC),[22] although it seems likely that this was oral ulceration as a manifestation of some infectious disease, since they are described as occurring in epidemic-like patterns, with concurrent symptoms such as fever. Aphthous stomatitis was once thought to be a form of recurrent herpes simplex virus infection, and some clinicians still refer to the condition as "herpes" despite this cause having been disproven.[23] The informal term "canker sore" is sometimes used, mainly in North America,[24] either to describe this condition generally, or to refer to the individual ulcers of this condition,[25] or mouth ulcers of any cause unrelated to this condition. The origin of the word "canker" is thought to have been influenced by Latin, Old English, Middle English and Old North French.[26] In Latin, cancer translates to ...
At-home treatments include desensitizing toothpastes or dentifrices, potassium salts, mouthwashes and chewing gums. A variety of toothpastes are marketed for dentin hypersensitivity, including compounds such as strontium chloride, strontium acetate, arginine, calcium carbonate, hydroxyapatite and calcium sodium phosphosilicate.[1] Desensitizing chewing gums[19] and mouthwashes are also marketed.[5] Potassium-containing toothpastes are common; however, the mechanism by which they may reduce hypersensitivity is unclear. Animal research has demonstrated that potassium ions placed in deep dentin cavities cause nerve depolarization and prevent re-polarization. It is not known if this effect would occur with the twice-daily, transient and small increase in potassium ions in saliva that brushing with potassium-containing toothpaste creates. In individuals with dentin hypersensitivity associated with exposed root surfaces, brushing twice daily with toothpaste containing 5% potassium nitrate for six to ...
The cause is uncertain,[5] but it is thought to be caused by accumulation of epithelial squames and proliferation of chromogenic (i.e., color-producing) microorganisms.[7] There may be an increase in keratin production or a decrease in normal desquamation (shedding of surface epithelial cells).[5] Many people with BHT are heavy smokers.[5] Other possible associated factors are poor oral hygiene,[5] general debilitation,[5] hyposalivation (i.e., decreased salivary flow rate),[7] radiotherapy,[5] overgrowth of fungal or bacterial organisms,[5] and a soft diet.[7] Occasionally, BHT may be caused by the use of antimicrobial medications (e.g., tetracyclines),[7] or oxidizing mouthwashes or antacids.[5] A soft diet may be involved as normally food has an abrasive action on the tongue, which keeps the filiform papillae short. Pellagra, a condition caused by niacin (vitamin B3) deficiency, may cause a thick greyish fur to develop on the dorsal tongue, along with other oral signs.[8] Transient surface ...
The exact pathogenesis is dependent upon the cause. Ulcers and erosions can be the result of a spectrum of conditions including those causing auto-immune epithelial damage, damage because of an immune defect (e.g., HIV, leukemia, infections e.g. herpes viruses) or nutritional disorders (e.g., vitamin deficiencies). Simple mechanisms which predispose the mouth to trauma and ulceration are xerostomia (dry mouth - as saliva usually lubricates the mucous membrane and controls bacterial levels) and epithelial atrophy (thinning, e.g., after radiotherapy), making the lining more fragile and easily breached.[19]:7 Stomatitis is a general term meaning inflammation within the mouth, and often may be associated with ulceration.[20] Pathologically, the mouth represents a transition between the gastrointestinal tract and the skin, meaning that many gastrointestinal and cutaneous conditions can involve the mouth. Some conditions usually associated with the whole gastrointestinal tract may present only in the ...
The focus of treatment is to remove plaque. Therapy is aimed at the reduction of oral bacteria and may take the form of regular periodic visits to a dental professional together with adequate oral hygiene home care. Thus, several of the methods used in the prevention of gingivitis can also be used for the treatment of manifest gingivitis, such as scaling, root planing, curettage, mouth washes containing chlorhexidine or hydrogen peroxide, and flossing. Interdental brushes also help remove any causative agents. Powered toothbrushes work better than manual toothbrushes in reducing the disease.[15] The active ingredients that "reduce plaque and demonstrate effective reduction of gingival inflammation over a period of time" are triclosan, chlorhexidine digluconate, and a combination of thymol, menthol, eucalyptol, and methyl salicylate. These ingredients are found in toothpaste and mouthwash. Hydrogen peroxide was long considered a suitable over-the-counter agent to treat gingivitis. There has been ...
Following active infection, herpes viruses establish a latent infection in sensory and autonomic ganglia of the nervous system. The double-stranded DNA of the virus is incorporated into the cell physiology by infection of the nucleus of a nerve's cell body. HSV latency is static; no virus is produced; and is controlled by a number of viral genes, including latency-associated transcript.[70] Many HSV-infected people experience recurrence within the first year of infection.[14] Prodrome precedes development of lesions. Prodromal symptoms include tingling (paresthesia), itching, and pain where lumbosacral nerves innervate the skin. Prodrome may occur as long as several days or as short as a few hours before lesions develop. Beginning antiviral treatment when prodrome is experienced can reduce the appearance and duration of lesions in some individuals. During recurrence, fewer lesions are likely to develop and are less painful and heal faster (within 5-10 days without antiviral treatment) than those ...
Diagnosis is suspected when a patient presents with the symptoms of the classic form of "Eagle syndrome" e.g. unilateral neck pain, sore throat or tinnitus. Sometimes the tip of the styloid process is palpable in the back of the throat. The diagnosis of the vascular type is more difficult and requires an expert opinion. One should have a high level of suspicion when neurological symptoms occur upon head rotation. Symptoms tend to be worsened on bimanual palpation of the styloid through the tonsillar bed. They may be relieved by infiltration of lidocaine into the tonsillar bed. Because of the proximity of several large vascular structures in this area this procedure should not be considered to be risk free. Imaging is important and is diagnostic. Visualizing the styloid process on a CT scan with 3D reconstruction is the suggested imaging technique.[8] The enlarged styloid may be visible on an orthopantogram or a lateral soft tissue X ray of the neck. It is worth noting that the styloid may be ...
The syndrome is rare in the United States, Africa and South America, but is common in the Middle East and Asia, suggesting a possible cause endemic to those tropical areas.[38] A theory suggested that past exposure to lethal infectious agents might have fixed the genetic susceptibility factors to Behçet's disease in those area.[39] It is not associated with cancer, and links with tissue-types (which are under investigation) are not certain. It also does not follow the usual pattern for autoimmune diseases. However, one study has revealed a possible connection to food allergies, particularly to dairy products.[40] An estimated 15,000 to 20,000 Americans have been diagnosed with this disease. In the UK, it is estimated to have about 1 case for every 100,000 people.[41] Globally, males are affected more frequently than females.[42] In the United States, more females are affected than males.[citation needed]. In an epidemiologic study, 56 percent of patients with Behçet's disease developed ocular ...
Symptoms include sudden fever with sore throat, headache, loss of appetite, and often neck pain. Within two days of onset an average of four or five (but sometimes up to twenty) 1 to 2 mm diameter grayish lumps form and develop into vesicles with red surrounds, and over 24 hours these become shallow ulcers, rarely larger than 5 mm diameter, that heal in one to seven days. These lesions most often appear on the tonsillar pillars (adjacent to the tonsils), but also on the soft palate, tonsils, uvula, or tongue.[5] A small number of lesions (usually 2 - 6) form in the back area of the mouth, particularly the soft palate or tonsillar pillars. The lesions progress initially from red macules to vesicles and lastly to ulcerations which can be 2 - 4 mm in size. ...
As abfraction is still a controversial theory there are various ideas on what causes the lesions. Because of this controversy the true causes of abfraction also remain disputable.[10] Researchers have proposed that abfraction is caused by forces on the tooth from the teeth touching together, occlusal forces, when chewing and swallowing.[3][11] These lead to a concentration of stress and flexion at the area where the enamel and cementum meet (CEJ).[2][4] This theoretical stress concentration[12] and flexion over time causes the bonds in the enamel of the tooth to break down and either fracture or be worn away from other stressors such as erosion or abrasion.[2][4][10][11] The people who initially proposed the theory of abfraction believe the occlusal forces alone cause the lesions[12] without requiring the added abrasive components such as toothbrush and paste or erosion.[12] If teeth come together in a non-ideal bite the researchers state that this would create further stress in areas on the ...
... are named after Henry Koplik (1858-1927), an American pediatrician who published a short description of them in 1896, emphasising their appearance before the skin rash and their value in the differential diagnosis of diseases with which measles might be mistaken.[4][6] He published two further papers on the spots, including one with a colour illustration.[7] An anonymous reviewer of Koplik's The Diseases of Infancy and Childhood refers to the illustration as "the now famous coloured plate".[8] Some authors ascribe the first written description of these spots to Reubold, Würzburg 1854, and others to Johann Andreas Murray (1740-1791). Before Koplik, the German internist Carl Jakob Adolf Christian Gerhardt (1833-1902) in 1874, the Danish physician N. Flindt in 1879, and the Russian Nil Filatov (1847-1902) in 1895, had observed equivalent phenomena.[9] Koplik was aware of Filatov's work,[10] thought his evidence insufficient and rejected his claim for priority.[7] ...
... infection occurs when the herpes simplex virus comes into contact with oral mucosal tissue or abraded skin of the mouth. Infection by the type 1 strain of herpes simplex virus (HSV-1) is most common; however, cases of oral infection by the type 2 strain are increasing.[11] Specifically, type 2 has been implicated as causing 10-15% of oral infections. Cold sores are the result of the virus reactivating in the body. Once HSV-1 has entered the body, it never leaves. The virus moves from the mouth to remain latent in the central nervous system. In approximately one-third of people, the virus can "wake up" or reactivate to cause disease. When reactivation occurs, the virus travels down the nerves to the skin where it may cause blisters (cold sores) around the lips, in the mouth or, in about 10% of cases, on the nose, chin, or cheeks. Cold sore outbreaks may be influenced by stress, menstruation, sunlight, sunburn, fever, dehydration, or local skin trauma. Surgical procedures such as ...
