Asynchronous idiopathic bone cavity: a case report.

Idiopathic bone cavity (IBC) is a non-odontogenic intra-osseous lesion that affects the jaws and others bones. The aetiology of IBC remains unknown. IBC is frequently observed as a single radiolucent area with a corticated, well-defined border, a scalloped shape and a minimal effect on the surrounding structures. A case report of asynchronous IBC in a 17-year-old woman is presented. The first lesion occurred in the mandibular symphysis region, and the second IBC occurred in the right mandibular ramus. Both lesions were surgically treated, and the patient has been disease-free for 5 years.

Taking advantage of an unerupted third molar: a case report

ABSTRACT Introduction: Treatments with dental surgery seek to displace tooth to the correct position within the dental arch. Objective: To report a clinical case that took advantage of an unerupted third molar. Case history: A male patient, 18 years of age, was referred by his dentist to evaluate the third molars. The clinical exam revealed no visible lower third molars. The computed tomography (CT) exam showed the presence of a supernumerary tooth in the region of the mandibular ramus, on the left side, and impaction of the third molar, which was causing root resorption on the second molar, thus making it impossible to remain in the buccal cavity. The preferred option, therefore, was to remove both second molar and the supernumerary tooth, in addition to attaching a device to the third molar during surgery for further traction. Results: After 12 months, the third molar reached the proper position. Conclusion: When a mandibular second permanent molar shows an atypical root resorption, an impacted third molar can effectively substitute the tooth by using an appropriate orthodontic-surgical approach.

Diaket® como Material Retrobturador: Relato de Casos

Resumo Na cirurgia endodontica denominada como retrobturacao, alem da correcta indicacao, sao primordiais um bom preparo apical e um bom material retrobturador. O material utilizado tem gerado controversias. Apresentamos neste relato tres casos de apicectomia com retrobturacao, em que, devido as suas propriedades fisicas e biologicas, obtivemos sucesso com o uso do Diaket®.
