Post Endodontic Treatment in Diabetic Patients and Correlation with their Glycemic Status: A Study

Abstract

Aim: The aim of this study was to investigate the prevalence of flare up post endodontic treatment in
diabetes mellitus (DM) patients and compare between the controlled and un controlled diabetic patients and
to examine the effect of glycemic control on the prevalence of flare ups.
Materials and Method: A study was conducted of convenience sampling among 20 diabetic patients from
a private dental clinic who had underwent Root canal treatment in the past one year and their post RCT
radiographs and glycemic status were collected in order to correlate the success and failure of endodontic
treatment.
Result: The prevalence of periapical pain was higher in uncontrolled diabetic group than in the controlled
diabetic group (13.5 vs 11.9% respectively) this difference was statistically significant (p = 0.000). The
poorly controlled DM group had a higher prevalence of the restored tooth being extracted post complications
compared with the well-controlled DM group (18.29 vs 9.21 respectively). This difference was statistically
significant (p = 0.000).
Conclusion: This survey therefore demonstrates a higher prevalence of flare ups in uncontrolled diabetic
patients compared with controlled diabetic group, with an increased prevalence of persistent chronic apical
periodontitis. Compared with a well-controlled diabetic group, a poor glycemic control may be associated
with a higher prevalence of Apical Periodontal disease and increased rate of endodontic failures.
