AIMS Several studies have shown a large diversity in the prevalence, extent and severity of gingival recession as well as controversial conclusions of its associated factors. Therefore, the aim of this pilot study was to evaluate gingival recession with predisposing factors in young Vietnamese. METHODS A cross-sectional study using clinical examination was performed in 120 dental students. Or...

In the developing tooth, 1-hydroxyethylidene-1,1-bisphosphonate (HEBP) causes hypoplasia and hypomineralization of enamel and dentine. The present study was undertaken to clarify the effects of HEBP on the formation of dental tissues of tooth germs in an organ culture system. Mandibular first molars from 17.5-day-old mouse embryos were cultured with or without 250 microM HEBP in culture medium....

OBJECTIVES This in vitro study evaluated the effectiveness of three carbamide peroxide concentrations used for tooth bleaching treatments. MATERIAL AND METHODS Sixty bovine dental slabs (6x6x3 mm) were obtained, sequentially polished, submitted to artificial staining (baseline) and randomized into four groups (n=15), according to the bleaching agent concentration: distilled water (control), 1...

buccal cavity as a compound ecosystem has always been ignored in parasitic infection studies; however it seems that studying on mouth and tooth prevalent parasitic infections is of great importance. in this study, from 120 patients of both sexes referred to faculty of dentistry, tehran university of medical sciences, iran, (2001-2002) 240 samples were taken from the plaques and calculus of dept...

In the previous study entitled " Specific Spindle Cells and Globular Substances in Enamel Knot" the auther reported that (1) the specific spindle cells appear at the free ends of the tooth bud and in the enamel knot, and they have a specific stain affinity and the characters of their staining powers are not nucleic-acid, and (2) certain irregular-shaped mesenchymal cells, whose nuclei showed al...

Many developments have been made in the field of resin composites for dental applications. However, the manifestation of shrinkage due to the polymerization process continues to be a major problem. The material's shrinkage, associated with dynamic development of elastic modulus, creates stresses within the material and its interface with the tooth structure. As a consequence, marginal failure a...

Caries can be controlled by the early treatment of the carious lesion, by alteration of conditions upon the tooth surface and by dietary means during the period of tooth formation. The incidence of dental caries is influenced by a large number of factors. After the teeth have erupted, local conditions on the surface of the teeth have the greatest influence, but tooth structure is of considerabl...

Hyperplastic dental follicle is an odontogenic hamartomatous lesion associated with delayed or tooth eruption failure in young patients. The occurrence of this pericoronal dental lesion may be single or multiple and it seems to be more frequent than literature has reported. We present a literature review focusing on the etiopathogenesis and clinicopathological features of this hamartomatous les...

AIM To investigate the expression of CD56 in dog odontogenesis in order to elucidate the expression found in ameloblastomas. MATERIALS AND METHODS Immunohistochemical analysis of CD56 expression of developing dog teeth in the bud, cap and bell stages including the remnants of the dental lamina. RESULTS Weak CD56 expression was observed in the dental epithelium during the bud stage with inte...
