CBCT or not CBCT: That is the Question

Pesquisa Brasileira em Odontopediatria e Clínica Integrada, 2017
Root fractures comprise approximately 0.5–7% of all traumatic injuries to the permanent dentition and frequently are diagnosed after trauma to the face and mouth. Horizontal fractures are most frequent in the middle third of the root and rare in the apical third, it occurs more often in the maxillary central incisors of male patients.

Management of post‐implant fibrous dysplasia in the maxilla: A case study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Fibrous dysplasia is generally rare, and even rarer in older adults. Special care is needed when altering the alveolar bone in these cases, especially if an implant is involved. This case study highlights such a scenario. Methods This case study details the experience of a 63‐year‐old African American female who presented with a ...
