The relationship between pulp calcifications and salivary gland calcifications.

Aim: Pulp stones are discrete calcified bodies found in the dental pulp. Sialolithasis is the most common salivary gland disease. The aim of the present study was to determine the relationship between the pulp stones and salivary gland stones.

Collision tumor of the palate: A rare case report.

This case report presents an unusual swelling of the palate in a 61-year-old-male patient. Histopathologically, it revealed features of two separate adjacent lesions, a spindle cells lesion showing diffuse immune-positivity for S-100 protein and focal positivity to glial fibrillary acid protein and an osseous lesion with numerous trabaculae of bone, adipocytes and myxoid tissue confirming the diagnosis of collision tumor of benign peripheral nerve sheath tumor and osteoma. Extensive search of English literature shows no reported cases of peripheral nerve sheath tumor with osteoma.

Prevalence of dental anomalies in Indian population.

Objectives: Developmental anomalies of the dentition are not infrequently observed by the dental practitioner. The aim of the present study was to determine the prevalence of dental anomalies in the Indian population.

Study Design: A retrospective study of 4133 panoramic radiographs of patients, who attended the Department of Oral Medicine and Radiology, Jodhpur Dental College General Hospital between September 2008 to December 2012 was done.

Prevalence of taurodontism in the North Indian population.

Objectives: Taurodontism affects primarily molars and premolars in both the deciduous and permanent dentition. The aim of the study was to assess the prevalence of taurodontism in the North Indian population.

Study Design: 4143 patients were studied by analyzing the panoramic radiographs for the presence of taurodontism which is defined as the presence of an apically displaced pulp chamber and the tooth lacks the usual constriction at the cementoenamel junction.

Prevalence of tongue lesions in the Indian population.

Objective: Tongue lesions are a health concern for the dental practitioners and the patients as they constitute a significant proportion of oral mucosal lesions. The aim of the present study was to determine the prevalence of various tongue lesions in the Indian population.

Material And Methods: 4926 patients attending the Department of Oral Medicine and Radiology were examined for the presence of various tongue lesions during the period from October, 2010 to September, 2012.

Analysis of the immunoexpression of Ki-67 and Bcl-2 in the pericoronal tissues of impacted teeth, dentigerous cysts and gingiva using software image analysis.

Background: Pericoronal tissue is the soft tissue located between the bony crypt and the impacted tooth, which is histologically composed of fibrous connective tissue and is usually lined by the reduced enamel epithelium. Increased epithelial cell proliferation in the pericoronal tissue is associated with pathological changes such as development of an odontogenic cyst or an epithelial odontogenic tumor. This study is an attempt to evaluate and compare the proliferative index in the epithelium surrounding the impacted third molar teeth, dentigerous cysts, and gingiva.

Epidemiological relationship of oral lichen planus to hepatitis C virus in an Indian population.

Aim: The relationship between the hepatitis C virus (HCV) and oral lichen planus (OLP) remains a controversial subject for clinicians. Many studies aimed at studying the association between HCV and OLP have been conducted over the years. Geographical variations have been shown to be a major factor influencing this association.

A study to evaluate the efficacy of toluidine blue and cytology in detecting oral cancer and dysplastic lesions.

Objective: Recent advances in techniques for detecting oral premalignant lesions and oral squamous cell carcinoma have improved the chances of early diagnosis. Adjuncts for detection of lesions include toluidine blue staining and cytologic examination. The primary objective of this study was to assess the efficacy of 1% toluidine blue (modified Mashberg technique) and cytology in detection of oral premalignant lesions and oral squamous cell carcinoma.

Dental DNA fingerprinting in identification of human remains.

The recent advances in molecular biology have revolutionized all aspects of dentistry. DNA, the language of life yields information beyond our imagination, both in health or disease. DNA fingerprinting is a tool used to unravel all the mysteries associated with the oral cavity and its manifestations during diseased conditions.
