Coronectomy: perception of bucco-maxillofacials in hospitals in Recife-PE

Abstract

Introduction: Coronectomy is an alternative treatment to the total removal of the impacted/included lower third molar, removing only the coronary region of the tooth, preserving its roots. The objective of this research is to measure the level of knowledge and perception of Surgeons and Buco-Maxillofacial Residents, in three public hospitals in the city of Recife, Pernambuco, on the technique of Coronectomy. Methodology: The sample consisted of 40 professionals, among whom 50% of all respondents stated that they did not perform the Coronectomy technique in the removal of third molars. Fisher's Exact Test was performed, which did not show any dependence between the interviewee categories regarding the degree of knowledge about the Coronectomy technique. Results: The interviewees are familiar with the Coronectomy technique, but its indication is not frequent and the most frequently mentioned contraindications were neoplastic lesions and third molars with apical pathology. The advantages of the procedure in relation to the total removal of third molars are considered very important and important. 70% of respondents see the need for reintervention as the biggest disadvantage in the technique; however, studies say that eruptions of these roots rarely occur. Conclusion: The Coronectomy technique is effective when correctly indicated and performed, as it reduces the risk of injury to the lower alveolar nerve.
