Abstract:
Objectives:To clarify whether the bone mineral density (BMD) differed from normal and whether the mandibular BMD changed with age in young adults with moderate periodontitis. Methods:30 patients (20-35 years old) with moderate adult periodontitis and 30 individuals (20-35 years old) with normal periodontal condition as control group were included in present study. BMD of the mandible was measured using panoramic mandibular index(PMI) from panoramic radiographic film. Results:The sPMI and iPMI value were 0.275 0?0.034 and 0.527 3?0.096 (normal group), 0.223 3?0.024 and 0.367 3?0.069 (periodontitis patients) respectively.The PMI value of periodontitis patients was significantly decreased compared to that of normal group, and showed a significant correlation with age.Conclusions:Moderate periodontitis in young adults seem to be a local disorder associated with relatively low PMI in the jaws. Age-related decrease in mean PMI with increasing age in both normal and periodontitis patients is founded.Dental panoramic radiograph may serve as a simple tool in mandibular BMD defection.
