Immunohistochemical staining for MCM2 and Ki67 markers was done and the slides were individually evaluated for MCM2 and Ki67 expression, with immunopositivity determined on the basis of dark brown staining of the nucleus.

A Digital Radiographic Study of Age Estimation Using Area-specific Formula in Odisha Population.

Aim: The aim of the article was to evaluate the feasibility of pulp/tooth area ratio in three mandibular teeth, namely left canine, left first premolar, and left second premolar (33, 34, and 35), as an indicator of age using digital panoramic radiograph and Kvaal's parameters. The study also aimed at computing an area-specific formula for age estimation in Odisha population.

Materials And Methods: Observation and analysis of 50 digital orthopantomographs (OPGs) and clinical data of patients were made.

Oral Sensations among Individuals with Illicit Drug Dependence in Rehabilitation Centers: A Cross-Sectional Study.

Background: In developing countries like India, irrespective of the various government laws and actions, substance abuse is a growing problem. Individuals with illicit drug dependence face social and psychological stigma with considerable health problems. Negligence to oral hygiene and lack of oral health treatments intensifies the sensations experienced by the subjects.

Assessment of knowledge of oral pathologists and postgraduate students on safe laboratory practices during the COVID-19 pandemic.

Background: Oral pathologists are involved in laboratory diagnosis and receive specimens of biopsy, oral cytologic smears and samples for hematology, biochemistry and microbiology and thus are at a risk for laboratory-acquired infections, which may occur inadvertently and can be considered as an occupational hazard.

Aim And Objectives: This study was conducted during the coronavirus disease (COVID-19) pandemic to assess the knowledge of oral pathologists and oral pathology postgraduate students regarding the safe laboratory practices, procedures and guidelines.

Materials And Methods: The study was a cross-sectional online questionnaire-based study.

Insight into the molecular pathogenesis of odontogenic lesions.

Background: Odontogenic tumors, derived from epithelial, ectomesenchymal, and/or mesenchymal elements of the tooth-forming apparatus, constitute a heterogeneous group of lesions, including hamartomas, benign and malignant neoplasms with metastatic capabilities.

Highlight: This review provides a comprehensive overviewof the pathogenesis of odontogenic tumors and explains the associated molecular events in the context of hallmarks of cancer established by Hanahan D and Weinberg RA. Diagrammatic representations depicted in the article would facilitate easier understanding.

Correlation of dental caries and dermatoglyphic patterns: A study in pediatric population.

Introduction: Dental caries is the most prevalent chronic disease among children worldwide irrespective of the advancements in oral healthcare. The basis of considering dermatoglyphic patterns as marker for dental caries is that the epithelium of finger buds and enamel are both ectodermal in origin and develop during the same period of intrauterine life.

Aim And Objective: To record and evaluate the dermatoglyphic patterns, its correlation with early childhood caries (ECC) and to predict its efficacy in assessing the caries risk.

The precedence and viability of yoga in the lives of D3-dental students, dental practitioners, and dental patients.

Dentistry as a profession is quite demanding and challenging and is also associated with occupational hazards like musculoskeletal disorders and stress-related problems. The practice of yoga has been proven to be efficacious in management of quite a lot of stress and lifestyle disorders. It strengthens one physically, mentally, and emotionally.

Collagen fibers in oral submucous fibrosis - A polarizing microscopy study using two special stains.

Background: Oral submucous fibrosis (OSMF), a well-recognized oral potentially malignant disorder, results due to increased collagen production and reduced collagen degradation.

Aims And Objectives: To qualitatively compare the staining properties of collagen in OSMF using two special stains based on their birefringent property using polarizing microscopy. The study also assessed the distribution and orientation of collagen fibers in different grades of OSMF.
