    Abstract:
    AIM: Osteoporosis and periodontitis are both chronic diseases characterised by bone loss. Potential association is of great clinical importance because of multifactorial aetiology and common risk factors. The aim of this study was to determine relationship between bone mineral density (BMD), tooth loss and periodontal status taking into account age, number of years since onset of menopause and educational level. With increasing age, number of years since onset of menopause and lower educational level, decreased BMD, deteriorating periodontal status and greater tooth loss are expected. MATERIALS AND METHODS: Cross-sectional study included 112 women aged 45-80 years (mean 58.3 years). BMD was determined for lumbar spine region and proximal femur by DEXA technology. Dental status and periodontal status were evaluated clinically and on panoramic radiographs. For the analysis of tooth loss frequency, participants were divided into four age groups. RESULTS: Significant inverse correlation was found between number of lost teeth and BMD at hip region (r = -.227; P = .028) but not at the lumbar spine (r = -.05; P = .669). Several indicators of the periodontal condition were significantly correlated with BMD, but not with postmenopausal period length. Important result is that participants missing one or more incisors or canines had significantly lower mean value of BMD comparing to those who had all the incisors and canines remained. CONCLUSION: Although osteoporosis is not the main cause of periodontitis, it may be a factor that leads to enhanced periodontal pocket depth and greater risk of tooth loss in ageing women.
