AB  - OBJECTIVE: The objective was to analyze radiomorphometric indices (RMIs) of 
      mandibular cortical bone and fractal dimension (FD) of trabecular bone of 
      individuals with osteogenesis imperfecta (OI) and compare the findings to those 
      of individuals without OI. METHODS: Digital panoramic radiographs of 20 
      individuals with OI (case group) and 40 individuals without OI (control group) 
      were examined. The RMIs of mandibular cortical index (MCI) and mandibular 
      cortical thickness (MCT) were analyzed. FD of mandibular trabecular bone was 
      calculated bilaterally in 3 regions. The chi-squared test and paired t test were 
      used to compare the significance of differences between the groups. The effect 
      size and minimal clinically important difference (MCID) were also determined. 
      Significance was established at P < .05. RESULTS: Categories C2 and C3 of the MCI 
      were more frequent in individuals with OI (P < .001). The Mean MCT was 2.08 +/- 
      0.79 in the OI case group and 2.91 +/- 0.60 in the control group (P < .001). Mean 
      FD in the condylar region was significantly lower in the OI case group 
      (P = .002). The effect size for these 2 measures was large, and the difference 
      between groups was greater than the MCID. CONCLUSION: Radiographs of individuals 
      with OI exhibited more porosity and diminished thickness of the mandibular 
      cortical bone and lower FD values in the condylar trabecular bone.
