Background: The Bellary district in Karnataka, rich in mineral resources, is a major mining industry, but prolonged exposure to mining can lead to health hazards. The study aims to assess the genotoxic impact of mining pollutants on mine workers using the micro-nucleus (MN) assay.
Setting And Design: Cross-sectional study.
Context: Plastination is one of the most advanced method for preserving perishable biological specimen as well as tissue samples as for a longer period of time using polymers.
Aims: To evaluate the changes in dimension of hard and soft tissue specimens after plastination procedure and compare it with the conventional method of preservation in formalin.
Settings And Design: Institution-based retrospective study.
The COVID-19 epidemic has affected not only people's daily lives but also the working methods of clinicians, surgical procedures, open/minimally invasive procedures, operating room management, patient and healthcare worker safety, education and training. The main objective of this study was to review selected articles and determine the changes in the general surgery protocols/procedures before and after the emergence of the COVID-19 pandemic. The literature was carried out in PubMed-Medline, Cochrane Library, Embase, Scopus and Google Scholar.

Aim: The aim of this study is to analyze and compare collagen fibers, their birefringence pattern in healthy and in diseased gingival tissues stained using picrosirius red stain (PRS) and the polarizing microscope.
Odontogenic keratocyst (OKC), in the last decade sceptically referred to as keratocystic odontogenic tumor (KCOT), is known for its subclinical extensive growth potential and significant rate of recurrences. Odontogenic keratocyst, being the third most common cystic lesion (10-20%) of the maxillofacial region, is often recognized as a sporadic lesion and is well-documented in the literature. Multiple presentation of these cysts over a lifetime is relatively uncommon and is usually seen in conjunction with nevoid basal cell carcinoma syndrome (NBCC), orofacial digital syndrome, Noonan syndrome, Ehlers-Danlos syndrome, Simpson-Golabi-Behmel syndrome, or other syndromes.

Objective measurement of psychosocial stress helps in assessment of pivotal role of stress in precipitation of multitude of health problems and a solution to the same. Salivary biomarkers are suggested to provide a reliable and non-invasive method for the estimation of these general health problems.

Aim: The purpose of this study was to evaluate the root canal morphology in maxillary first premolars using the clearing technique in a South Indian population.
Objective: To estimate the serum and salivary lactate dehydrogenase levels in cigarette smokers and non-smokers.
Materials And Methods: In this study lactate dehydrogenase levels were estimated in 30 healthy individuals with no tobacco related habits and in 30 patients with history of smoking cigarettes for a minimum of 2 years using Spectrophotometry.
Results: The mean values for serum and salivary lactate dehydrogenase levels were higher in cigarette smokers when compared to non-smokers.
Unicystic ameloblastoma (UCA) is a cystic lesion that shows clinical, radiographic, or gross features of an odontogenic cyst, but reveals a typical ameloblastomatous epithelium lining in the cyst cavity, with or without luminal and/or mural tumor growth. This article reports the case of a 22-year-old man with dull intermittent pain and swelling in the mandible. Histopathological examination revealed a UCA of a luminal, intraluminal, and intramural histological subgroup, which has a high risk for recurrence.
View Article and Find Full Text PDFOdontomas are hamartomatous lesions composed of mature enamel, dentin, and pulp, and may be compound or complex depending on the extent of morphodifferentiation or on their resemblance to normal teeth. They are the most common benign odontogenic tumours, constituting 22% of all odontogenic tumours of the jaw. They are often non-aggressive and slow growing in nature, and are usually diagnosed on routine radiological examinations in the second decade of life.
