ABSTRACT
Background: Diabetes mellitus is a metabolic disease and affects many organs of the body including oralmucosa. Exfoliative cytology can be used to detect the effects of diabetes on buccal mucosa cells.Aim: The present study will evaluate the qualitative changes (cytomorphology) of buccal mucosal cells in type 2diabetic patients and compare that with the non-diabetic individuals of South Gujarat region.Materials and Method: Present study was done on 50 type 2 diabetic patients (case) and 50 healthy individuals(control) selected as per exclusion and inclusion criteria. Procedure was explained to the participants andinformed written consent was taken. Buccal mucosa smears were taken and stained with Pap’s stain. 100 cellsof each Pap stained smear was examined under a research microscope for various cytomorphological changes.Smears were examined for cell morphology like binucleation, pyknosis, perinuclear halo, cytoplasmic granules,karyolysis, karyorrhexis, cytoplsmic vacuoles and micronuclei. All data were noted and subjected to statisticalanalysis.Results: Mean values of binucleated cells, pyknotic cells, perinuclear halo, cytoplasmic granules, karyolyticcells, karyorrhectic cells, cytoplasmic vacuoles and micronuclei were noted in controls and cases. Significantdifferences in between non-diabetic control and diabetic cases for mean values of binucleation (p<0.001),pyknosis (p<0.001), perinuclear halo (p<0.001), cytoplasmic granules (p<0.001), karyolysis (p=0.026) andkaryorrhexis (p<0.001) was observed. But no significant differences in the mean cells for cytoplasmic vacuoles(p=0.109) and micronuclei (p=0.176) were found between diabetics cases and non-diabetics control.Conclusion: The results of present study showed that buccal mucosa of diabetic case group is associated withsignificant differences in the mean values of qualitative changes like binucleation, pyknosis, perinuclear halo,cytoplasmic granules, karyolysis and karyorrhexis when compare to non-diabetic control group. Diabetesproduces significant qualitative (cytomorphologic) changes in the buccal mucosa cells that can be documentedby exfoliative cytology.
