[Application of dietary supplement to periodontal disease and osteoporosis].

It is known that there is a relationship between various systemic diseases, life style and periodontal disease. In such a situation, it is becoming clear a relationship between the systemic bone density and the mandibular bone, alveolar bone density and clinical periodontal parameters. And it is also cleared that to lower common risk factors related to these conditions might be useful to prevent osteoporosis and periodontal disease. As it is reported that medical treatment such as hormone replacement therapy (HRT) is effective not only preventing lowering skeletal bone density but also maintaining mandibular and alveolar bones, it is also considered that continuing supplementation of some nutritions such as calcium and isoflavone is also expected to have preventive effects.
