Coronectomy - An alternative approach to remove impacted teeth in oncological patients.

subject

description

Background Coronectomy involves the section of the tooth crown leaving the roots in the socket. Possibility of inferior alveolar nerve injury and mandibular fracture are the main indications for this approach. Herein, we describe a case series of coronectomy to highlight its indication in normal and oncological patients. Material and methods A total of 9 patients were submitted to coronectomy, 6 of them were oncological. Three patients were evaluated before head and neck radiotherapy (HNRT), 2 after HNRT and 1 before bone marrow transplantation. Results Mean age of the patients was 49 years, most of them male (n=7). Lower third molars were the main teeth that received this procedure, and all cases presented intimate anatomic relationship between the roots and the mandibular canal. Moreover, three cases also presented evident mandibular fracture risk in removing the tooth. During the follow-up period, none complications were observed related to coronectomy and oncological treatment. Conclusions Coronectomy is a safe approach including for cancer patients and it should be considered in high-risk impacted teeth extractions. Key words:Coronectomy, impacted teeth, oncological patients, postoperative complications.
