The aim of this study is to evaluate the trabecular bone density in the mandible diagnosed with sleep bruxism (SB) using the fractal analysis method on panoramic radiographs.


37 patients whose anamnesis and clinical signs were compatible with SB were diagnosed with SB using BiteStrip®. Three areas were identified on the panoramic radiographs of the patients: geometric center of the condyle, angulus region under the mandibular canal, and distal region of mental foramen. ROIs of 60x60 pixels were selected in these three locations, and fractal dimensions (FD) were calculated. Results were compared and analyzed with the control group.


There was no statistically significant difference between right and left FD values, also, male and female FD values in the all regions and both groups. (p>0,05) In the angulus (p=0.03) and condyle (p=0.03) regions, SB group had a significantly higher FD value than control group. There was no statistically significant difference between SB and control groups in the corpus region. (p=0.98) A moderate negative correlation arose between age and condyle FD values among controls. (r= –0.38, p=0.02)


FD value evaluating trabeculation of the mandibular bone are affected by SB in the angulus and condyle regions.
