ABSTRACT
OBJECTIVE: 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.
METHODS: 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 60×60 pixels were selected in these three locations, and fractal dimensions (FD) were calculated. Results were compared and analyzed with the control group.
RESULTS: 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) CONCLUSION: FD value evaluating trabeculation of the mandibular bone are affected by SB in the angulus and condyle regions.
