Abstract:
The aim of this work is to study the prevalence of AP in patients with
and without type 2 diabetes mellitus. In a retrospective cohort study, the
records of 38 subjects with diabetes and 32 control
subjects were examined. All participants underwent a
full-mouth radiographic survey incorporating 14
periapical radiographs. The periapical region of all
teeth, excluding third molars, was examined. Periapical
status was assessed using the periapical index
score. Statistical analyses were conducted using the
Cohen’s j test, analysis of variance and logistic
regression. Apical periodontitis in at least one tooth was
found in 81.3% of diabetic patients and in 58% of
control subjects (P ¼ 0.040; OR ¼ 3.2; 95% CI ¼ 1.1–
9.4). Amongst diabetic patients 7% of the teeth had AP,
whereas in the control subjects 4% of teeth were
affected (P ¼ 0.007; OR ¼ 1.8; 95% CI ¼ 1.2–2.8).
Type 2 diabetes mellitus is significantly
associated with an increased prevalence of AP.
