Determination of physical height from crown dimensions of deciduous tooth: A dental morphometric study.

Background: Dental morphometrics is a subject of great significance in forensic odontology in identification of an individual. Use of teeth to represent a physical profile is valuable for identification of an individual.

Aims And Objectives: The present study aims to assess the clinical crown length (CL) of erupted deciduous teeth and height of the child.

Evaluation of transforming growth factor beta1 gene in oral submucous fibrosis induced in Sprague-Dawley rats by injections of areca nut and pan masala (commercial areca nut product) extracts.

Context: Oral submucous fibrosis (OSF) is a potentially malignant oral disorder causally linked to the habit of chewing arecanut. The pathogenesis of the disorder is multifactorial and transforming growth factor beta (TGF-beta) is a prominent player in the induction of fibrosis. The alkaloids of the arecanut seem to target the TGF-beta and the deposition of collagen is predominantly mediated through this cytokine.

Sexual dimorphism in tooth morphometrics: An evaluation of the parameters.

Aims And Objectives: Sexual dimorphism refers to the variations in tooth size and shape between the sexes. The consistency of these variations is valuable in the identification of the sex of an individual in times of mass disaster when whole body parts get destroyed or are unavailable. There exist differences in the expression of these variables across races and regions.

Surgical Interventions in Oral Submucous Fibrosis: A Systematic Analysis of the Literature.

Background: Oral submucous fibrosis (OSMF) is a potentially malignant disorder of the oral cavity. The surgical management of this condition involves excision of the fibrotic bands and interpositional grafts to retain the increased oral opening. Various procedures and graft material have been utilised with differing success rates.

Transforming growth factor-β1 and TGF-β2 act synergistically in the fibrotic pathway in oral submucous fibrosis: An immunohistochemical observation.

Background And Objectives: Oral Submucous Fibrosis (OSF) is a potentially malignant oral disorder which leads to fibrosis of the oral mucosa and has a high rate of malignant transformation. The consumption of various forms of areca nut is causatively linked to the condition. The constituents of areca nut activate several pro-fibrotic cytokines, chiefly transforming growth factor-β1, β2, which leads to an increased deposition and decreased degradation of extracellular matrix and collagen.

Amelogenin in odontogenic cysts and tumors: An immunohistochemical study.

Background: Amelogenins are the major enamel proteins that play a major role in the biomineralization and structural organization of enamel. Aberrations of enamel-related proteins are thought to be involved in oncogenesis of odontogenic epithelium. The expression of amelogenin is possibly an indicator of differentiation of epithelial cells in the odontogenic lesions.

Oral lichenoid lesions - a review and update.

Background: Oral lichenoid lesions or reactions (OLLs/OLRs) are clinical and histological contemporaries of the classical oral lichen planus (OLP) that have generated a lot of debate in literature. In contrast to the idiopathic nature of OLP, OLLs are often associated with a known identifiable inciting factor. A superficial examination of these lesions clinically and histologically often reveals many similarities with OLP, but recent data indicate that distinguishable features do exist and form the basis of most classifications.

Spindle cell variant of ameloblastic carcinoma arising from an unicystic amelobastoma: Report of a rare case.

Malignant transformation of ameloblastomas arising from an odontogenic cyst or de novo is well-recognized. Malignancies in ameloblastomas may involve metastasis or a local dysplastic change in the tissue. The latter are classified as ameloblastic carcinomas.

Benign hyperplasia of duct-associated lymphoid tissue: report of a case and review of literature.

Focal lymphoid tissue is ubiquitously present in the oral mucosa and serves as a barrier for entrapment of antigens. The mucosa-associated lymphoid tissue is generally dispersed and sometimes associated with the ducts of the minor salivary glands. Proliferation of the duct-associated lymphoid tissue (DALT) is rarely reported, though probably of common occurrence.
