Cytomorphometric analysis of gingival epithelium and buccal mucosa cells in type 2 diabetes mellitus patients

Abstract

Background:

The global prevalence of type 2 diabetes continues to rise. Interest has been increasing recently in noninvasive diagnostic procedure. Hence, an attempt has been made by the present study to analyze the changes in cytomorphometry in exfoliated buccal and gingival mucosa cells in type 2 diabetic patients.

Aim:

The aim of this study was to analyze the cytomorphometric changes in exfoliated cells of gingiva and buccal mucosa as an adjunct to diagnosis of diabetes.

Materials and Methods:

In the present study, fifty known type 2 diabetic patients were taken as study group, and the control group was comprised of fifty healthy individuals. Smear was prepared from buccal mucosa and gingival epithelium of both study and control groups and was stained by rapid Papanicolaou (Pap) stain. Stained smears were subjected to cytomorphometric analysis using Lynx Biolux (Lawrence and Mayo) image analysis software. In each Pap smear, 100 cells were evaluated for nuclear area (NA), cytoplasmic area (CA) and cytoplasm to nuclear ratio (CNR).

Results:

Mean NA was significantly higher ( P < 0.05) in study group whereas mean CA did not exhibit any statistically significant difference ( P > 0.05). The mean CNR was significantly lower in the study group ( P < 0.05).

Conclusion:

This study contributes to the general understanding of the alterations in the cellular pattern of buccal and gingival mucosa cells in diabetic patients and can be used as an additional tool to aid in the evaluation of oral mucosal alterations in diabetes mellitus.
