Effects of ovariectomy on turnover of alveolar bone in the healed extraction socket in rat edentulous mandible.

Objective: The number of patients with postmenopausal osteoporosis receiving dental implants because of edentulism is increasing. Since osseointegration around implants requires formation and maintenance of new bone, knowledge of how ovariectomy (OVX) affects turnover of mandibular and maxillary bone is required. In the present study, we investigated the effects of OVX on turnover of alveolar bone in the healed extraction socket of the rat left mandibular incisor.

Effects of lactation on alveolar bone loss in experimental periodontitis.

Background: The development and progression of periodontitis are accelerated by various systemic conditions. The present study was designed to determine whether lactation affects alveolar bone loss in rat models of experimental periodontitis.

Methods: Sixty-two female Wistar rats were bred with male rats and divided into three groups that were fed diets containing 0.

Periodontitis is a local inflammatory disease mainly induced by periodontopathic bacteria including Porphyromonas gingivalis. This disease is characterized by the destruction of periodontal tissues including alveolar bone, which is accelerated by various local and systemic factors. In recent years, many investigators focused on the relationships between periodontitis and systemic diseases such as diabetes and osteoporosis.
