Bisphosphonates (BPs) are commonly used for the treatment of osteoporosis and bone metastases. BPs have a positive treatment effect (e.g., increase in bone tissue density) on the long bones but a negative side effect (e.g., osteonecrosis) on the corpus of the mandible is reported. It is not known whether the jaw joint is also affected by BP treatment. We hypothesize that application of bisphosphonates will affect the jaw joint.
The application of BP resulted in bone-site specific changes in mineralization; an effect that to our knowledge has never been reported before. This regional BP effect might explain the excessive increase in bone volume combined with the lack of increase in mineral density compared to the control group.
Next, the bone analysis results found in the jaw joint will be compared to the knee joint of the same animals. Besides microCT, histological and histomorphometric analysis will be added to the study.
