Comparative Analysis of Cytomorphology in Adolescent and Geriatric Patients: A Cross-Sectional Study

Background Exfoliation of the surface cells of the normal epithelium occurs as a result of physiological turnover. Epithelial cells are constantly renewed, and they are exfoliated or shed as they migrate from the basal layer to the uppermost layer of the epithelium. Oral exfoliative cytology involves the collection and microscopic evaluation of these shed cells or scraped epithelial cells, quantitatively and qualitatively. The objective of the present study was to analyze and compare the cytomorphometric features like cellular area, nuclear area, and nuclear-cytoplasmic ratio from buccal mucosal smears of adolescent and geriatric patients. This study highlights the changes in cell morphology in different age groups (adolescent and pediatric), which could be attributed to hormonal, habitual, and aging factors. Material and methods Buccal smear sample was collected from a total of 60 individuals belonging to the age groups of 11-19 years and above 60 years. The smears were stained with H&E and PAP (Papanicolaou) stain. Photomicrographs were taken in 40x, and measurements were calculated using ImageJ software (National Institutes of Health, Bethesda, Maryland, United States). Cellular size, nuclear size, and nucleo-cytoplasmic ratio were analyzed and compared between the two age groups using independent t-tests using IBM SPSS Statistics for Windows, Version 22.0 (Released 2013; IBM Corp., Armonk, New York, United States). Results A significant difference was observed in the cellular area and nuclear area between the two age groups with a p-value of 0.00. No significant findings were present in the nucleo-cytoplasmic area of the two age groups. Conclusion Cytomorphometric analysis has shown that there were variations in the cytoplasmic and nuclear areas among different age groups.
