Relationship between mandibular fracture and impacted lower third molar
Many studies have shown that the greatest risk of fracture of the mandibular angle is related to the presence of an unerupted lower third molar, based on the hypothesis that there is a decrease in the area of bone and absorption of the impact in this area, leading some surgeons to indicate its prophylactic removal in patients most exposed to the risk factors of facial trauma. On the other hand, other authors have observed a greater frequency of condylar fractures in patients without an impacted lower third molar.Purpose: The aim of this study was to relate the condylar and angle fracture with an unerupted lower third molar, taking into account the position of the tooth.Material and Methods:…
Extensive osteonecrosis of the maxilla caused by bisphosphonates: Report of a rare case
Bisphosphonates are drugs indicated for the treatment of bone metabolic diseases or malignant hypercalcemia. They are generally well-tolerated drugs, however, recent reports have described osteonecrosis of the jaw bones as a potentially serious complication related to the long-term use of these drugs. We report a case of severe osteonecrosis in a 52-years-old white woman that was taking bisphosphonates (zoledronic acid and alendronate) for the management of osteoporosis. Following a long exposure to these drugs and after being subjected to multiples exodontias, developed bisphosphonate-related osteonecrosis of the jaw compromising the whole maxilla and that extended toward the base of skull…
