Objectives: Diabetes mellitus is a chronic disease and its association with endodontic disease has been well studied but available information using very large hospital database is scarce. Utilizing large hospital databases can be very useful in not only providing patient information but much needed larger sample sizes for comparing differences across groups. The aim of this study was to compare the prevalence of endodontic infection among diabetics and non-diabetics using the University of North Carolina Hospital (UNC) database system.

Methods: Carolina Data Warehouse for Health (CDW-H), the largest data repository for University of North Carolina Hospitals (UNC) was searched to identity patients admitted between October 2015 and September 2017, using ICD-10 codes (K04.4-K04.7) for pulp and periapical disease, and (E11) for Diabetes Mellitus. De-identified data with no other demographic information was obtained. Chi-square tests were used to compare differences between diabetics and non-diabetics and across various glycemic levels in patients with endodontic disease respectively.

Results: The search yielded a total of 1,239,574 patients, of whom 63,398 (5.1%) had diabetes. Among 4,748 patients with endodontic disease, 455 (9.6%) had diabetes. Diabetics with and without endodontic disease were tricotomized across HbA1c glycemic levels of none (<6.5), moderate (6.5-8) and high (>8). The prevalence of endodontic disease was almost twice as high among diabetics when compared to those without diabetes (0.71% vs. 0.36%; p<0.0001). The prevalence of endodontic disease among diabetics also increased across the 3 increasing levels of HbA1c (0.62%, 0.64%, 0.99%; p<0.0001).

Conclusions: Compared to the non-diabetics,the prevalence of endodontic disease was higher among diabetics with increasing glycemic levels.
