[Osteoporosis].

Abstract

Osteoporosis is an increasing major skeletal disease leading to disability. It is important to define this disease precisely, because the start is without any symptom in many cases. Causal factors are reviewed as also recognisable risk factors in early stage. The available recent literature and own studies did not show relationship between tooth loss, bone loss of the mandible, periodontitis and osteoporosis. However, corticosteroids diminish mandibular bone mass. Assessment to bone mineral density is a major diagnostic test for osteoporosis prediction. Recent findings in prevention and treatment of osteoporosis are reviewed extensively. The positive results of oestrogen replacement therapy on the oral bone loss and tooth loss from some large observational American studies are interesting.
