Long-term effect of tobacco on unstimulated salivary pH.

Aims And Objectives: The aim of this study was to analyze and compare the effects of tobacco on salivary pH between tobacco chewers, smokers and controls.

Materials And Methods: A total of 60 subjects (males and females) aged 25-40 years, were divided equally into three groups: Tobacco smokers (Group A), chewers (Group B) and controls (Group C). Saliva of each subject was collected under resting condition.

Artefacts produced by normal saline when used as a holding solution for biopsy tissues in transit.

Oral surgeons, surgeons and dentists carrying out small biopsy procedures on an out-patient basis have been frequently sending poorly stored biopsy tissues to the Departments of Oral Pathology of various dental colleges, wherein the tissues were being stored in normal saline and then transferred to formalin. Such tissues often show abnormal cellular and architectural changes, which pose a challenge to diagnosis, especially when the histopathologist is not aware that the tissue was stored in normal saline for some time. We wanted to know the extent of artefactually induced cellular and architectural changes in tissues that were transported in normal saline and received by us, based on the duration for which they were held in normal saline.

Forensic odontology as a victim identification tool in mass disasters: A feasibility study in the Indian scenario.

Aim: The aim of this study was to evaluate the awareness of practicing dentists about the subject of forensic odontology and to assess their willingness to maintain and share patient records.

Materials And Methods: A blind questionnaire survey was carried out among 100 randomly selected practicing dentists in district Ghaziabad, Uttar Pradesh.

Results: Most of the dentists interviewed were familiar with the subject of forensic odontology and its relation to dentistry, despite forensic dentistry having been newly introduced since 2007 into the undergraduate dental curriculum in India.

HPV involvement in OSCC: Correlation of PCR results with light microscopic features.

Objectives: The study evaluated pathognomic histopathological features with the help of light microscopy for detecting the integration of human papillomavirus (HPV) (type 16 and 18) in oral squamous cell carcinoma (OSCC).

Materials And Methods: Forty-five histopathologically diagnosed cases of OSCC were evaluated for the presence of E6/E7 protein of HPV (16 + 18) with the help of nested multiplex polymerase chain reaction. Both HPV-positive and -negative cases were evaluated for four histological features: Koilocytes, dyskeratosis, invasion, and alteration of collagen.

Primary intraosseous carcinoma of the mandible: A report of two cases.

Primary intraosseous carcinoma arising as a de novo lesion is a unique and rare carcinoma affecting the jaws, especially at younger ages. Two case reports, a 26-year-old Indian female with primary intraosseous squamous cell carcinoma and a 16-year-old Indian male with intraosseous carcinoma arising in an odontogenic cyst, both within the body of the mandible, are presented here.
