Bcl-2 expression in reactive oral lesions with atypical epithelium and in oral epithelial dysplasia associated with carcinogen exposure.

Background: Reactive lesions of the oral cavity are nonneoplastic proliferations with very similar appearance to benign neoplastic lesions and are associated with chronic local irritation or trauma. Although these lesions are uncommonly associated with carcinogen exposure, at times, they present histopathologically with dysplastic epithelium, thus making it difficult to differentiate it from true potentially malignant disorders. Hence, the present study was conducted to evaluate the expression of Bcl-2 protein, an antiapoptotic marker, in reactive lesions with and without atypical epithelium and in true epithelial dysplasia, which clinically presents as premalignant disorders.

Effects of salivary thiocyanate levels on oral mucosa in young adult smokers: A biochemical and cytological study.

Background And Objectives: Cigarette smoking is one of the major global health issues. Accurate measurement of smoking is essential for accepting patterns of adolescent smoking behavior and for the evaluation of health education programs aimed at reducing or preventing the habit. The aim of the present study was to estimate and compare the salivary thiocyanate levels in young adult smokers and nonsmokers and also to evaluate and correlate the cellular and nuclear changes in cytological smears with salivary thiocyanate levels.

Habit-associated salivary pH changes in oral submucous fibrosis-A controlled cross-sectional study.

Context: Oral submucous fibrosis (OSF) is a multi-causal inflammatory reaction to the chemical or mechanical trauma caused due to exposure to arecanut containing products with or without tobacco (ANCP/T). Arecanut and additional components such as lime and chewing tobacco render ANCP/T highly alkaline. Fibrosing repair is a common reaction to an alkaline exposure in the skin.

Halitosis - An overview: Part-I - Classification, etiology, and pathophysiology of halitosis.

Halitosis is a condition where the breath is altered in an unpleasant manner for the affected individuals and impairs them socially as well as psychologically. Halitosis can be clinically classified as real halitosis, pseudohalitosis, and halitophobia. Real halitosis has oral and extra-oral etiologies and the pathophysiology involves interaction of anaerobic microbes (mainly) with the proteins present in the oral cavity fluids and contents, resulting in production of volatile sulfur compounds (VSCs).

Predentin thickness analysis in developing and developed permanent teeth.

Background: Predentin, the unmineralized organic matrix is important in maintaining the integrity of dentin. It is usually thick where active dentinogenesis occurs. A wide variation in its thickness is reported.

Dimensional and morphological analysis of various rugae patterns in Kerala (South India) sample population: A cross-sectional study.

Background: Analysis of palatal rugae patterns, which are similar to fingerprints, is one of the techniques used in forensic sciences for human identification. As palatal rugae patterns are genetically determined, they can also be used in population differentiation and gender determination. Hence, we aimed to record the distribution of the predominant rugae pattern in Kerala population.

Granularity in granular cell ameloblastoma.

Granular cell ameloblastoma (GCA) is one of the rare histological variants of ameloblastoma (1.5-3.5%), identified by Krompechner in 1918 and is diagnosed by the characteristic presence of granular cells.

Analysis of prevalence and clinical features of multicystic ameloblastoma and its histological subtypes in South Indian sample population: A retrospective study over 13 years.

Objective: The study was designed to analyze the frequency and clinical features of multicystic ameloblastoma and its histological variants in South Indian sample population, as there is minute information available in the English literature.

Methodology: The study source was the biopsy specimens retrieved from the archives of the Department of Oral and Maxillofacial Pathology, College of Dental Sciences, Davangere, Karnataka, India, during the past 13 years, from 2001 to 2013. Clinical data for the study were obtained from the case records of patients and the analyzed clinical variables were age, gender and anatomical location.

Prevalence and clinicopathological comparison of kerotocystic odontogenic tumor and orthokeratinized odontogenic cyst in South Indian sample population: A retrospective study over 13 years.

Aim And Methodology: The purpose of this study is to determine the prevalence of keratocystic odontogenic tumor (KCOT) and orthokeratinized odontogenic cyst (OOC), to identify their clinicopathological features among the patients by studying the biopsy specimens obtained from the archives of the Department of Oral and Maxillofacial Pathology, College of Dental Sciences, Davangere, Karnataka, India during the period of 2001-2013.
