Method: Forty-three females with GDM and 41 non-diabetic pregnant females were included in the study. Serum samples were collected and full-mouth periodontal examination was performed consisting of plaque index (PI), bleeding on probing (BOP) and probing depth (PD). Age, smoking status and pregestational body mass index (pre-BMI) were obtained. Fasting plasma glucose levels (FPG), and HOMA index were measured. Kruskal-Wallis followed by Bonferroni-corrected post hoc Mann-Whitney U tests were used to analyze the data.
Result: The women with GDM were significantly older than the non-diabetic pregnant women (P=0.001). The FPG level and HOMA index were significantly higher in the GDM group than the non-diabetic group (P <0.0001 and P<0.0001, respectively). There were no significant differences in the PI and BOP. The women with GDM revealed significantly higher PD than the non-diabetic counterparts (P=0.049).
Conclusion: The results suggest that gingival disease may be associated with GDM. Therefore, physicians may be advised to ask for clinical periodontal evaluation of pregnant women.
