Objective
The aim was to perform fractal analysis (FA) to compare differences in trabecular
microarchitecture in interdental and antegonial regions on panoramic radiographs in
periodontally healthy patients and those with stage III/IV, grade C periodontitis,
and to compare the effects of patient age and sex on FA results.
Study Design
Clinical and radiographic records from 33 periodontally healthy individuals and 28
individuals with aggressive periodontitis were obtained from the faculty archives.
Three regions of interest (ROIs) were chosen bilaterally from interdental bone around
the mandibular first molar and canine and the antegonial region. The mean fractal
dimension (FD) values of the ROIs were calculated. Significance of differences was
established at P < .05.
Results
FD values of all 3 ROIs in the periodontitis group were significantly lower than values
in the control group (P ≤ .004). FD was not affected by patient age (P = .357) or sex (P = .216). There were no significant correlations between FD and age in either group
(P ≥ .093). FD values differed significantly between sexes in only one ROI.
Conclusions
FA can effectively detect trabecular microarchitectural differences in patients with
aggressive periodontitis compared to periodontally healthy individuals. This technique
might be useful in predicting the susceptibility of patients to periodontal disease.
