Background: Liquid-based cytology (LBC) can be used for the evaluation of micronucleus (MN) in exfoliated buccal epithelial cells of populations occupationally exposed to potentially carcinogenic agents.
Aim: This study was undertaken to evaluate the frequency of MN of exfoliated buccal epithelial cells using LBC preparation in petrol station workers.
Materials And Methods: Fifty petrol station workers (cases) and fifty hospital administrative staffs (controls) were recruited and evaluated for MN by May-Grunwald Giemsa, Hematoxylin and Eosin, and Papanicolaou stains using LBC preparation. Statistical analysis was performed with Student's -test, and < 0.05 was considered statistically significant.
Results: Regardless of staining method used, the mean frequency of MN for cases was significantly higher than that of controls ( < 0.001).
Conclusion: The present study concluded that petrol station workers are under risk of significant cytogenetic damage. The MN in exfoliated buccal epithelial cells found to be a useful biomarker of occupational exposure to genotoxic chemicals. LBC can be used for sample preparation to evaluate the frequency of MN in those who are occupationally exposed to potentially carcinogenic agents in view of overall improvement on sample preservation and visualization of cell morphology.

Article Synopsis
- The pilot study focused on the presence of micronuclei (MN) and other nuclear abnormalities in oral mucosa cells from patients with type I, II, and LADA diabetes, comparing results to healthy individuals.
- Cytogenetic analysis indicated that diabetes patients had significantly higher levels of MN, particularly in type I and LADA groups, suggesting potential cytotoxic and genotoxic effects of the disease.
- There was a strong correlation found between MN levels, blood glucose concentration, and glycosylated hemoglobin, highlighting the impact of diabetes on cellular health.

Introduction: The incidence of post-pandemic psychiatric disorders has increased globally in recent decades. Generalized anxiety disorder (GAD) is one of the psychiatric disorders that are partially associated with emotional factors. It can affect the quantity and quality of saliva, present as xerostomia, and trigger the emergence of the geographic tongue (GT).

Introduction: The practice of dentistry benefits greatly from cone beam computed tomography (CBCT) and advantages should be prioritized over hazards; even modest doses of X-rays have the potential to have cytotoxic effects, damage DNA through their clastogenic impact, and stimulate the creation of micronuclei along with further nuclear changes.
Aims And Objectives: To assess the genotoxicity and cytotoxicity of X-rays in exfoliated oral mucosal cells from patients who underwent CBCT scans at different fields of view (FOV), and to examine and assess the extent of cytotoxicity and genotoxicity caused by X-rays in oral exfoliated cells of people who were subjected to CBCT at different fields of view (FOV).
Material And Methods: Following CBCT exposure, 66 patients were chosen from the Department of Oral Medicine and Radiology at the SVS Institute of Dental Sciences, Mahbubnagar.

Objectives: To determine the genetic effects of panoramic radiography on the epithelial cells of the buccal mucosa by examining the micronucleus formation in these cells.
Materials And Methods: In this cross-sectional study, exfoliative cytology samples were prepared from the buccal mucosa of 36 patients immediately before and 10 days after panoramic radiography. The samples were prepared using liquid-based cytology with Papanicolaou staining.
