The root surface in human teeth: a microradiographic study. (1/170)

In an attempt to clarify the nature of the human cemento-dentinal junction, ground sections of incompletely formed and fully formed extracted teeth were prepared and their histology compared with their microradiographic appearances. The results showed that incompletely formed teeth possess distinctive surface layers outside the granular layer of Tomes. The evidence indicates that these layers are of dentinal origin; their presence during development supports previous explanations by the author of the hyaline layer of Hopewell-Smith and of so-called intermediate cementum. The results also indicate that the granular layer of Tomes does not represent the outer limit of root dentine. The relationship of these surface layers to the definitive cementum which is present in fully formed teeth was studied in both young and older patients. From the results it was concluded that cementum formation begins in the more apical region of the teeth at a time when root formation is well advanced, and that it spreads towards the crown rather than in the generally accepted reverse direction.  (+info)

Histological and histochemical quantification of root resorption incident to the application of intrusive force to rat molars. (2/170)

This study was conducted to investigate the nature of root resorption resulting from intrusive forces applied to the rat lower molars, by means of histological and histochemical techniques with tartrate resistant acid phosphatase (TRAP). Thirty-eight 13-week-old Wistar strain male rats were used. Intrusive force was created by a fixed appliance which was adjusted to exert an initial force of 50 g for the duration of 1, 2, and 3 weeks. The degree of root resorption and distribution of TRAP positive cells were evaluated. On the root surface, the TRAP positive scores were low in the apical regions. Significant differences in the scores were found in the inter-radicular region of the roots between the experimental and control groups for the 2- and 3-week groups. More active resorption of bone occurred during the experimental period, as denoted by greater TRAP positive scores on the bone than on the root surface. Root resorption scores in the apical root region were larger in the 2- and 3-week groups than in the 1-week group. Significant differences in the root resorption scores were also found between the 1- and 3-week groups in the inter-radicular region, indicating that intrusive force application of a longer duration may lead to a higher frequency of root resorption. It is shown that, irrespective of the level of TRAP positive cells and root resorption scores, the degree of root resorption activity is higher in the apical root region than in the inter-radicular area. These results indicate that cellular cementum may be resorbed more easily because of its richer organic components and low mineralized structure.  (+info)

Evolution of periodontal regeneration: from the roots' point of view. (3/170)

Tissues lost as a consequence of periodontal diseases, i.e. bone, cementum and a functional periodontal ligament (PDL), can be restored to some degree. Nevertheless, results are often disappointing. There is a need to develop new paradigms for regenerating periodontal tissues that are based on an understanding of the cellular and molecular mechanisms regulating the development and regeneration of periodontal tissues. As one approach we have developed strategies for maintaining cementoblasts in culture by first determining the gene profile for these cells in situ. Next, cells were immortalized in vitro using SV 40 large T antigen (SV40 Tag) or by using mice containing transgenes enabling cellular immortality in vitro. Cementoblasts in vitro retained expression of genes associated with mineralized tissues, bone sialoprotein and osteocalcin, that were not linked with periodontal fibroblasts either in situ or in vitro. Further, cementoblasts promoted mineralization in vitro as measured by von Kossa and ex vivo using a severely compromised immunodeficient (SCID) mouse model. These cells responded to growth factors by eliciting changes in gene profile and mitogenesis and to osteotropic hormones by evoking changes in gene profile and ability to induce mineral nodule formation in vitro. The ultimate goal of these studies is to provide the knowledge base required for designing improved modalities for use in periodontal regenerative therapies.  (+info)

Growth factors regulate expression of mineral associated genes in cementoblasts. (4/170)

BACKGROUND: Knowledge of the responsiveness of cells within the periodontal region to specific bioactive agents is important for improving regenerative therapies. The aim of this study was to determine the effect of specific growth factors, insulin-like growth factor-I (IGF-I), platelet-derived growth factor-BB (PDGF-BB), and transforming growth factor-beta (TGF-beta) on cementoblasts in vitro and ex vivo. METHODS: Osteocalcin (OC) promoter driven SV40 transgenic mice were used to obtain immortalized cementoblasts. Growth factor effects on DNA synthesis were assayed by [3H]-thymidine incorporation. Northern analysis was used to determine the effects of growth factors on gene expression profile. Effects of growth factors on cementoblast induced biomineralization were determined in vitro (von Kossa stain) and ex vivo (re-implantation of cells in immunodeficient (SCID) mice). RESULTS: All growth factors stimulated DNA synthesis compared to control. Twenty-four hour exposure of cells to PDGF-BB or TGF-beta resulted in a decrease in bone sialoprotein (BSP) and osteocalcin (OCN) mRNAs while PDGF-BB also increased osteopontin (OPN) mRNA. Cells exposed to IGF-I for 24 hours exhibited decreased transcripts for OCN and OPN with an upregulation of BSP mRNA noted at 72 hours. In vitro mineralization was inhibited by continuous application of PDGF-BB or TGF-beta, while cells exposed to these factors prior to implantation into SCID mice still promoted biomineralization. CONCLUSIONS: These data indicate IGF-I, PDGF-BB, and TGF-beta influence mitogenesis, phenotypic gene expression profile, and biomineralization potential of cementoblasts suggesting that such factors alone or in combination with other agents may provide trigger factors required for regenerating periodontal tissues.  (+info)

Cell-specific patterns of Cbfa1 mRNA and protein expression in postnatal murine dental tissues. (5/170)

Cbfa1 (core binding factor alpha 1) is a transcription factor that is a key determinant of the osteoblastic lineage. Recent data showed that Cbfa1 is also highly expressed in early stages of tooth development and is involved in crown morphogenesis and cytodifferentiation of odontoblasts. Here we report the mRNA expression and protein localization of Cbfa1 in the mouse dentition in (later) stages of crown and root development. In addition to osteoblasts, osteocytes, chondrocytes, odontoblasts, dental follicle cells, cementoblasts and periodontal ligament cells, we report also Cbfa1 expression in dental epithelial cells (secretory and maturation ameloblasts) and several non-mineralizing cell types (hair follicles, ducts of salivary glands, and junctional epithelium of the gingiva).  (+info)

Ultrastructure of cementum and periodontal ligament after continuous intrusion in humans: a transmission electron microscopy study. (6/170)

An ultrastructural study of the cementum and periodontal ligament (PDL) changes after continuous intrusion with two different and controlled forces in humans was carried out. Twelve first upper premolars, at stage 10 of Nolla, orthodontically indicated for extraction from six patients (mean age 15.3) were used. They were divided into three experimental groups, distributed intra-individually as follows: control (not moved), continuously intruded for 4 weeks with 50 or 100 cN force, utilizing a precise biomechanical model with nickel titanium super-elastic wires (NiTi-SE), which were developed and calibrated individually. The teeth were extracted, fixed, decalcified, and conventionally processed for examination in a Jeol 100 CX II transmission electron microscope. Evident signs of degeneration of cell structures, vascular components, and extracellular matrix (EM) of cementum and PDL were observed in all the intruded teeth, with more severe changes towards an apical direction and in proportion to the magnitude of force applied. Resorptive areas and an irregular root surface of the intruded teeth were noticed, according to the same pattern described above. Concomitant, areas of repair were also revealed in the cementum and PDL although the magnitude of forces remained the same throughout the experimental period. Thus, a reduction of continuous force magnitude should be considered to preserve the integrity of tissues.  (+info)

Platelet-derived growth factor (PDGF) gene delivery for application in periodontal tissue engineering. (7/170)

BACKGROUND: A challenge in the reconstruction of periodontal structures is the targeted delivery of growth-promoting molecules to the tooth root surface. Polypeptide growth factors such as platelet-derived growth factor (PDGF) stimulate both cementogenesis and osteogenesis. Recent advances in gene therapy offer the advantage of delivering recombinant proteins to tissues for extended periods of time in vivo. METHODS: Recombinant adenoviral vectors encoding for the PDGF-A gene were constructed to allow delivery of PDGF transgenes to cells. The recombinant adenoviruses were assembled using the viral backbone of Ad2/CMV/EGFP and replacing GFP (reporter gene encoding green fluorescent protein driven by the cytomegalovirus promoter [CMV] within adenovirus type 2) with the PDGF-A gene. Root lining cells (cloned cementoblasts) were transduced with Ad2/PDGF-A and evaluated for gene expression, DNA synthesis, and cell proliferation. PDGF-inducible genes, c-myc and osteopontin, were also evaluated following gene delivery of Ad2/PDGF-A. RESULTS: The results revealed high level transduction of cementoblasts by gene transfer for 7 days as evidenced by flow cytometry and Northern blotting. Cementoblast DNA synthesis and subsequent proliferation were stimulated by Ad2/PDGF-A at levels equal to or greater than continuous rhPDGF-AA application. Strong message for the PDGF-A gene and protein as evidenced by Northern blotting and immunocytochemistry was noted. Furthermore, the potent induction of c-myc and osteopontin mRNA was found after PDGF gene delivery to cementoblasts. CONCLUSIONS: These findings demonstrate that gene delivery of platelet-derived growth factor stimulates cementoblast activity that is sustained above that of rhPDGF-AA application. The use of gene therapy as a mode of growth factor delivery offers a novel approach to periodontal tissue engineering.  (+info)

The developmental biology of cementum. (8/170)

In conclusion, we have reviewed an extensive literature on early cementogenesis and performed a detailed morphological and molecular analysis to illustrate and verify key issues in the current debate about epithelial and mesenchymal contributions to root cementum. We have demonstrated that prior to cementogenesis, Hertwig's epithelial root sheath disintegrates and dental follicle cells penetrate the epithelial layer to invade the root surface. Our studies confirmed that HERS became disrupted or disintegrated prior to cementum deposition. We visualized how mesenchymal cells from the dental follicle penetrated the HERS bilayer and deposited initial cementum, while immediately adjacent epithelial cells were separated from the root surface by a basal lamina and did not secrete any cementum. Human specimen from the Gottlieb collection indicated that HERS was removed from the root surface prior to cementum deposition. Our in situ hybridization and immolocalization data revealed that both amelogenin mRNAs and enamel proteins were restricted to the crown enamel and were absent from the root surface and from the cervical-most ameloblasts adjacent to the root margin. On Western blots, cementum protein extracts did not cross-react with amelogenin antibodies. Our studies in conjunction with our literature review together confirmed the classical theory of cementum as a dental follicle derived connective tissue that forms subsequent to HERS disintegration.  (+info)

There are three hard tissues that comprise human teeth: enamel, dentin and cementum. The majority of the tooth structure is formed from dentin, and the enamel serves as the superficial layer of the crown while the cementum serves to cover the root. In the mid-1990s, however, it was discovered that a very thin layer of enamel actually exists between the dentin and cementum on the roots of adult human teeth. This led researchers to conclude that enamel matrix proteins (or EMPs) laid down by Hertwigs epithelial root sheath serve as precursors to acellular cementum during its formation, known as cementogenesis.[1] The presence of acellular cementum acts to signal the development of periodontal ligament fibers, followed by new alveolar bone, thus leading to the formation of the tissues of the periodontium.[2]. ...

BSP is multifunctional, affecting cell attachment and signaling through an RGD integrin-binding region, and acting as a positive regulator for mineral precipitation by nucleating hydroxyapatite crystals. BSP is present in cementum, the hard tissue covering the tooth root that anchors periodontal ligament PDL attachment.. Results collected here suggest that BSP plays a non-redundant role in acellular cementum formation, likely involved in initiating mineralization on the root surface. Through its importance to cementum integrity, BSP is essential for periodontal function.

Meanwhile, since he was sedated for the ultrasound, the vets took a closer look at Fitz teeth. His gums were receding so much that the roots of two teeth were almost entirely exposed. One had a huge tartar cap on it that was so hard it took a Dremel to drill through it and break it apart. (Weve since heard this abnormal tartar buildup called a cementoblast.) As the vet drilled into the cementoblast, the bit went right through what should have been tooth behind it and into dead bone. The infection in the tooth had moved into the bone and caused some decay. A second infected incisor was also removed, but there was no bone involvement in relation to that one. That left one more incisor with most of the root exposed, but it still seemed to be firmly in place and not infected, so it was left alone for the time being ...
Root cementum represents one of the crucial prerequisites for an intact fixation in the tooths osseous socket, the alveole. Healthy cementum and its self-repair mechanisms are furthermore vital to a sound parodontium and thus for the entire dental health. Central to the thesis at hand was the collection of human cementoblasts from extracted teeth. These had to be cultivated, immortalized and characterized. The ensuing examination covered an analysis of proteins that are presumed typical for cement and bone. Such proteins include collagen type I and III, osteocalcin, osteopontin, bone sialoprotein and osteonectin. Other findings include both transcription factors RUNX2 and SOX9, both of which are not extensively researched in context with cementum yet. This holds true in particular for SOX9. Even though typical for the chondrogenic cell line, this transcription factor and its interrelation with cementum is not covered in relevant literature. In contrast to this, the literary research has ...
There is disclosed a novel device for providing heat to dental and periodontal structures and a novel process for brightening teeth, together with a novel use of old known processes for brightening teeth. The novel device comprises a splint/stint or vacumformed dental tray, containing a heating element to be placed around the tooth or teeth to be brightened. The novel process for brightening/whitening teeth entails using the splint containing the heating element in conjunction with standard tooth whiteners with a brightening agent. The heating element is attached to a power source, preferably mobile and transportable, so that the process may be accelerated by the heating of the brightening agent, in accordance with the Q10 rule.
The goal of Periodontal therapy is to halt the disease progression and prevent its recurrence, and restore the lost periodontal structure which occured as the result of the disease destruction. The later goal prompts us to evaluate the concept of new attachment or regeneration, and reattachment or repair. Each concepts will lead to different mode of periodontal therapy, and ultimately different result. New attachment is the ideal, desired goal, which each periodontist today are trying to achieve in every possible way. Continue reading →. ...

Title:Role of the Epithelial Cell Rests of Malassez in Periodontal Homeostasis and Regeneration - A Review. VOLUME: 10 ISSUE: 5. Author(s):Zhenhua Yang, Yanjiao Li, Xiaojie Ma, Lin Shen, Zhihe Zhao and Fang Jin. Affiliation:145 West Changle Road, Xian, Shaanxi 710032, PR China;. Keywords:Hertwigs epithelial root sheath, epithelial cell rests Malassez, periodontium development, periodontal regeneration, cementogenesis, stem cells.. Abstract:Predictable and complete periodontal regeneration following periodontitis has been the ultimate goal of periodontal treatment. It has been recognized that Hertwigs epithelial root sheath (HERS) cells play a crucial role in cementogenesis and root formation. As the descendants of HERS and unique odontogenic epithelium in the adult periodontium, epithelial cell rests of Malassez (ERM) have long been considered as quiescent epithelial remnants devoid of structure and function. Here we will present an overview of our present understanding and putative functions ...

AU - Kunii, Ryotaro. AU - Shimauchi, Hidetoshi. PY - 2005/9/1. Y1 - 2005/9/1. N2 - Retinoic acid (RA) exerts a wide variety of effects on development, cellular differentiation and homeostasis in various tissues. However, little is known about the effects of RA on the differentiation of periodontal ligament cells. In this study, we investigated whether RA can affect the dexamethasone-induced differentiation of periodontal ligament cells. Human periodontal ligament cells were differentiated via culturing in the presence of dexamethasone, ascorbic acid, and β-glycerophosphate for mineralized nodule formation, as characterized by von Kossa staining. Continuous treatment with all-trans-RA inhibited mineralization in a dose-dependent manner, with complete inhibition over 1 μM RA. Other RA analogs, 9-cis-RA and ...
The cells of cementum are the entrapped cementoblasts, the cementocytes. Each cementocyte lies in its lacuna, similar to the pattern noted in bone. These lacunae also have canaliculi or canals. Unlike those in bone, however, these canals in cementum do not contain nerves, nor do they radiate outward. Instead, the canals are oriented toward the periodontal ligament and contain cementocytic processes that exist to diffuse nutrients from the ligament because it is vascularized. After the apposition of cementum in layers, the cementoblasts that do not become entrapped in cementum line up along the cemental surface along the length of the outer covering of the periodontal ligament. These cementoblasts can form subsequent layers of cementum if the tooth is injured. Sharpey fibers are part of the principal collagenous fibers of the periodontal ligament embedded in the cementum and alveolar bone to attach the tooth to the alveolus.[2] ...

External apical root resorption is a common phenomenon associated with orthodontic treatment. The factors relevant to root resorption can be divided into biological and mechanical, with some of them associated with an increased risk of root resorption during orthodontic treatment. As far as mechanical factors are concerned, extensive tooth movement, type of movement (eg, root torque and intrusion), and magnitude and duration of orthodontic forces have been highly correlated to root resorption. There is no consensus, nor are there other clinical studies regarding, specific evidence of how jiggling forces can affect the pattern and amount of root resorption. In this study, we investigated how the application of buccopalatal jiggling movement with light and heavy forces affected root surfaces and how the quantitative properties of resorption craters were altered, thus determining whether different buccopalatal jiggling force levels have different adverse effects on root resorption and quantified ...

Background and Objective: Cell adhesion plays important roles in maintaining the structural integrity of connective tissues and sensing changes in the biomechanical environment of cells. The objective of the present investigation was to extend our understanding of the effect of cyclic mechanical strain on the expression of adhesion-related genes by human periodontal ligament cells. Material and Methods: Cultured periodontal ligament cells were subjected to a cyclic in-plane tensile deformation of 12% for 5s (0.2Hz) every 90s for 6-24h in a Flexercell FX-4000 Strain Unit. The following parameters were measured: (i)cell viability by the MTT assay; (ii)caspase-3 and -7 activity; and (iii)the expression of 84 genes encoding adhesion-related molecules using real-time RT-PCR microarrays. Results: Mechanical stress reduced the metabolic activity of deformed cells at 6h, and caspase-3 and -7 activity at 6 and 12h. Seventy-three genes were detected at critical threshold values <35. Fifteen showed a ...
Detail of the period when the root sheath cells (blue) secrete enamel matrix proteins. Following formation of the protein matrix on the surface of the mineralizing dentin, cementoblasts (Red) start producing cementum (Light blue) which anchors collagen fibers.. The Next Generation. In the mid 1980s, a revolutionary breakthrough in the basic biology of tooth development took place at the Karolinska Institutes department of Oral Pathology in Stockholm. The discovery revealed a native complex of enamel matrix proteins and the key if not crucial , role they play in the development of tooth-supporting tissues. These enamel related proteins mediate the formation of acellular cementum on the root of the developing tooth, providing a foundation for all of the necessary tissues associated with a functional periodontal attachment.. This groundbreaking discovery has fueled the development of a new generation in periodontal therapy, and makes the recreation of lost tooth support an attainable goal in the ...

Canine periodontal disease (gum disease) is the most common cause of tooth loss and is a source of chronic bacterial infection, contributing to adverse health conditions including kidney failure and endocarditis. Treatment options are limited and their benefits remain uncertain due to a lack of evidence-based research. The cause of canine periodontal disease is accumulation of plaque under the gum line that leads to inflammation and progressive erosion of normal periodontal structures, including the gums, tooth root and supporting facial bones. The first step in the evolution of gum disease is development of a periodontal �pocket;� a gap between the gum line and tooth margin that traps food and bacteria and promotes continued destruction of these supporting structures. In healthy gums the depth of the periodontal space measures less than 2 millimeters. With periodontal disease this space becomes larger, and consensus opinion is that deep pockets promote rapid progression of gum disease. Detection of
Impacted Tooth: A tooth that is prevented from erupting by a physical barrier, usually other teeth. Impaction may also result from orientation of the tooth in an other than vertical position in the periodontal structures.
Immunohistochemical Localization of Osteopontin - A Comparative Study on Periodontally Healthy and Diseased Tooth Root Surface, Julie Toby Thomas, Toby
The authors report the clinical and histologic data on the healing of a severe periodontal lesion obtained in a one-walled intrabony defect using anorganic bovine bone under a bovine peritoneum-derived collagen membrane. Eight months after surgery, a bone-like tissue replaced the lost tissues. A biopsy of this tissue was carried out. In the part of the specimen closer to the residual bony wall of the original defect, anorganic bone particles (ABP) appeared to be surrounded by a layer of newly formed bone; its osteocyte lacunae were colonized by osteocytes from the host, and actively secreting osteoblasts were observed in many microscopic fields. No resorption phenomena were observed in the ABP. Newly formed cementum with actively secreting cementoblasts was present on the tooth surface, and well-oriented fibers inserting in both newly formed cementum and bone were observed. In an area far from residual bone, all ABP did not appear to be surrounded by newly formed bone. Osteocytic lacunae ...

BACKGROUND AND OBJECTIVE: The antimicrobial peptide LL-37 is expressed in periodontal tissue, and variations in LL-37 levels have been associated with periodontal disease. The effects of LL-37 on periodontal ligament cell function have not been described before. Here, we assess anti-inflammatory properties of LL-37 and investigate the effects of LL-37 on cell differentiation, cell proliferation and apoptosis in human periodontal ligament cells. MATERIAL AND METHODS: Periodontal ligament cells were obtained from teeth extracted for orthodontic reasons. Cytokine (interleukin-6) and chemokine (monocyte chemoattractant protein-1) expression was determined by quantitative PCR, cell differentiation by alkaline phosphatase activity, cell proliferation by counting cells in a Bürker chamber, DNA synthesis by incorporation of radiolabeled thymidine and apoptosis by cell morphology and activated caspase 3 quantities. RESULTS: Treatment with 0.1 and 1 μm of LL-37 totally reversed ...
MAPK is a Ser/Thr protein kinase that is widely expressed in various cells. Through a cascade reaction, the MAPK pathway transduces signals to the cell nucleus to regulate transcription, and therefore influences cell proliferation, apoptosis and differentiation (12). In the MAPK family, ERK1/2, p38 and JNK subfamilies have been extensively investigated. ERK1/2 and p38 are involved in osteogenesis-associated gene expression and bone formation in vivo (13,14). However, the full underlying mechanism of ERK1/2 and p38 pathways in osteogenic differentiation remains contradictory. Li et al (14) revealed that when the ERK1/2 and p38 signaling pathways were inhibited in dental follicle cells, osteogenic differentiation in early, middle and advanced stages was promoted. However, Xiao et al (15) reported that inhibition of ERK1/2 resulted in restrained osteoblast activity and bone formation. Therefore, ERK1/2 may exert positive or negative effects on osteogenic differentiation, which may result from ...

Background. Stem cells have contributed to the development of tissue-engineered-based regenerative periodontal therapies. In order to find the best stem cell sources for such therapies, the biologic properties of stem cells isolated from periodontal ligaments (PDL) of deciduous (DePDLSC) and permanent (PePDLSC) teeth were comparatively evaluated. Methods. PDL stem cells were isolated from six sound fully erupted premolars and six deciduous canines of healthy subjects. In vitro biologic characteristics such as colony formation, viability, stem cell marker identification and osteogenic differentiation (using alkaline phosphatase analysis and Alizarin red staining) were comparatively assessed using one-way ANOVA and post hoc Tukey tests using SPSS 13 ...
Context: Smokers are at a higher risk of contracting periodontitis. This association is established and reported in many studies. Periodontitis is a polymicrobial disease, wherein smoking is an environmental factor which aggravates the damage caused to the tissues. Procalcitonin (ProCT) is a well-known marker for inflammatory and other infectious diseases and has been assessed in this study. It has been observed that the release of reactive oxygen species (ROS) is exaggerated in smokers. Antioxidants are administered to combat the harmful effects caused by the ROS, and Oxitard™ is a powerful herbal antioxidant that can counteract the action of free radicals. Aims: As smokers are more prone to tissue injury due to excessive release of ROS, this study aimed to understand the benefits of systemic administration of Oxitard after scaling and root planing (SRP) on serum ProCT levels in smokers with chronic periodontitis (CP). Settings and Design: This was a randomized interventional study, wherein ...

The only treatment for affected teeth at an advanced stage is extraction. Horses can manage quite well without their incisor teeth and should be able to eat a normal diet, including hay and even grazing. There are several ongoing studies looking into the causes and potential treatment options for this syndrome.. Molly Rice, DVM, and Travis Henry, DVM, DAVDC, who are currently studying the disease, say that many horses arent diagnosed until the end stages of the disease process, which is incredibly painful. If horses can be diagnosed and treated at an earlier stage, their quality of life can be improved greatly. In our practice we recommend radiographs of the incisors after the age of 15 to screen for resorptive lesions. This is a quick 10-minute process that can be performed during the horses routine dental examination. Over the past six years, we have treated over 200 cases similar to Peanuts. The extraction process is performed under standing sedation with local nerve blocks. The ...

The good news is that cementum can repair itself. Cementoblasts - cells in your tooth root - make cementum continuously throughout your life as the old cementum ages and thins. This way your teeth stay firmly embedded in your jawbone.. Your goal is to support this natural repair process, to neatly close off your exposed dentinal tubules with cementum.. Cementum is about 50% hydroxylapatite. Tooth enamel is 90% hydroxylapatite, and bone is 70%. Hydroxylapatite is a calcium phosphate mineral, also known as the bone mineral.. Acid food and drinks dissolve hydroxylapatite, and hence cementum. Enamel begins to demineralize at a pH of 5.5.. Yet another reason to eat a high-alkaline diet! When raw fooders eat too much acidic citrus, it dissolves their tooth enamel. They get sensitive teeth. Watch those oranges and lemons. Juice them, or rinse your mouth after eating.. The other 50% of cementum (the part that isnt calcified hydroxylapatite) is mainly collagen and protein polysaccharides (compounds of ...
Dental stem cells, especially dental follicle cells (DFCs) as precursor cells for the periodontium have interesting prospects for regenerative dentistry. During periodontitis, butyrate as a bacterial metabolite and inflammatory agent is often found in millimolar concentrations in periodontal pockets. This study evaluates the effects of butyrate on the proliferation and osteogenic differentiation of DFCs. We assessed cell viability/proliferation (BCA assay) and osteogenic differentiation (ALP activity, alizarin staining and RT PCR) of DFCs in vitro after butyrate supplementation. Butyrate concentrations of 20 mM or higher are toxic for DFCs. At a non-toxic concentration, butyrate promotes the expression of alkaline phosphatase and collagen type-1 but inhibits the formation of calcified nodules and the induction of RUNX2 and osteocalcin under osteogenic differentiation conditions. In conclusion, DFCs are resistant to physiological high concentrations of butyrate. Butyrate facilitates the ...

The use of guided tissue regeneration procedures has intensified the need to determine the types and quantity of tissues formed in healing. Regeneration is differentiated from new attachment in one basic, but very important manner: alveolar bone formation with new inserted periodontal fibers in new cementum is a prerequisite for the regeneration of periodontium (4-6). Areas of new cementum deposition without adjacent bone, and vice-versa, and areas of ankylosis, for example, do not satisfy the criteria for regeneration (7). Furthermore, recent advances in the understanding of functions and mechanisms of action of growth factors to regulate the healing process have provided evidence that these proteins may serve as therapeutic agents to enhance the healing of periodontal wounds (8-11). Sigurdsson et al. (12) found a significant enhancement in periodontal regeneration using the rhBMP-2 in dog models. They described limited root resorption and ankylosis generally limited immediately apical to the ...
Objective: To evaluate the kinetics of bone formation of Pool 7 EMD, by concentration, on the amount of marrow formation and study factors relating to angiogenesis associated with EMD-induced bone formation. Methods: Fractionated commercial Emdogain® (EMD) was obtained from Straumann International. 60 CDI 7 day old outbred mice were injected using 50 μl aliquots of 10 µg EMD, 10 µg Pool 7 EMD, 2 µg TGF-β (positive control) or phosphate buffered saline (PBS, negative control) delivered in a calvarial injection model. Injections were done for 5 consecutive days. The animals were sacrificed on days 6, 8, 12, 16 and 21 with 6 animals per factor for each time point and were prepared for histological evaluation. Nikon NIS Elements software was used to analyze vascular growth and new bone formation over the five time intervals at 20x magnification. Immunocytochemistry (IHC) was used to identify the kinetics of osteogenesis by evaluating the osteoblast transcription factor Osterix, and the ...
In the cementum located at the end of the middle third and throughout the apical third the gaps are occupied by cementocytes with numerous interconnecting extensions in the form of a spider web. The cementocytes are also found in large numbers in furcation areas. Their gaps interconnect with the cementocytes, making metabolic exchanges with the odontoblastic extensions of the neighboring dentin (Figs 4, 5 and 6).. In the bone, a network of osteocytes is formed through contact with approximately twenty cells. This interconnecting network exchanges fluids and mediators, keeping the mineralized bone matrix metabolically active and connected to the internal and external bone surfaces. It is likely that this interconnecting network may capture structural deformations by applying compressive forces and bone stretching, which results in cytoskeleton deformation and release of mediators that stimulate adaptive cellular activities on the surfaces of medullary and cortical spaces.. In the cementum, it ...

Swimming is a great way to exercise the joints with minimal damage.[3] A joint disorder is termed arthropathy, and when involving inflammation of one or more joints the disorder is called arthritis.
