Evaluation of DNA damage in tobacco associated human buccal cells using comet assay.

Aim And Objective: To assess the DNA damage in tobacco associated human buccal cells using comet assay.

Methods: The study included 75 study subjects, which were divided into 3 groups on the basis of tobacco usage. Group I - 25 individuals with no history of tobacco usage, Group II - 25 individuals with tobacco usage but without oral lesions and Group III - 25 individuals with tobacco associated oral lesions.

Molecular Pathogenesis and Diagnostic Imaging of Metastatic Jaw Tumors.

Metastasis is the spread of malignant cells from a primary tumor to distant sites through lymphatics or blood vessels. Malignant lesions metastasizing to the oral and perioral region are a rarity indeed. Malignant lesions could metastasize to both soft tissue of oral cavity and the hard tissues of the jaws and recent meta-analysis showed that metastasis is more common in the jaws than oral soft tissues because of rich vascular supply.

Configuration of frontal sinuses: A forensic perspective.

Background: Identification of an individual whether living or deceased is of paramount importance in maintaining the integrity of the society. A simple, reliable, and efficacious method always finds a way for easier acceptance and inclusion in any discipline. Likewise, identification of an individual using the radiographic frontal sinus patterns is a simple technique which emphasized to conduct the study with a proven result.

A clinical study on oral lichen planus with special emphasis on hyperpigmentation.

Background: Oral lichen planus (OLP) is a unique disorder affecting generally the older age group. Numerous studies have been done on various aspects of OLP such as pathogenesis, rate of malignant transformation, etc. However, very few studies are available with respect to clinical features especially association of hyperpigmentation and OLP.

Harvesting dental stem cells - Overview.

Dental stem cells have recently become one of the widely researched areas in dentistry. Ever since the identification of stem cells from various dental tissues like deciduous teeth, dental papilla, periodontal ligament and third molars, storing them for future use for various clinical applications was being explored. Dental stem cells were harvested and isolated using various techniques by different investigators and laboratories.

Role of proteomics in physiologic and pathologic conditions of dentistry: Overview.

Proteomics is the study of structure and function of proteins in a large scale. For any living organism, preteins are considered to be the vital part because of its role in metabolic pathways of cells. These proteins not only play a role in physiological condition of the cell but also in altered manner during pathologic conditions.

Dermatoglyphic patterns and salivary pH in subjects with and without dental caries: A cross-sectional study.

Background: Dermatoglyphic patterns, which are regularly used in judicial and legal investigations, can be valuable in the diagnosis of many diseases associated with genetic disorders. Dental caries although of infectious origin, may have a genetic predisposition. Hence, we evaluated the correlation between dental caries and dermatoglyphic patterns among subjects with and without dental caries and evaluated its association with environmental factors such as salivary pH.
