Abstract text
Background & Aim: To compare differences in trabecular microarchitecture in mandibular first molar interdental bone on panoramic radiographs using fractal analysis in stage III/IV periodontitis patients with and without diabetes mellitus (DM).
Methods: Clinical records (CAL, PD, BOP, PI, FI) and radiographic parameters (bone loss and density) were obtained from 12 systemically healthy (control) stage III/IV periodontitis patients and 12 individuals with stage III/IV periodontitis and DM at University setting. One region of interest (ROIs) was chosen bilaterally from the interdental bone around the mandibular first molar. The mean fractal dimension (FD) values of the ROIs were calculated.
Results: A total of 25 generalized periodontitis patients, including 12 with DM (4 patients: Stage III Grade B and 8 patients: Stage IV Grade C) and 13 controls (4 patients: Stage III Grade B and 9 patients: Stage IV Grade C) were included to the study. The mean age of the study population was 52.8 ± 1.3 and 62% (n = 17) were female. No significant difference was observed between patients with DM and the control group in terms of mandibular molar interdental FD values (1.58 ± 0.10 vs 1.55 ± 0.12, p = 0.243).
Conclusions: The presence of diabetes mellitus was not associated with reduced bone structure, as evaluated by fractal analysis in patients with similar periodontal conditions. Further investigation is required to assess different HbA1c levels grade modifier-in periodontitis patients with diabetes mellitus.
