RESUMEN
PURPOSE: The purpose of this study was to assess success rates and to report complications of coronectomy of mandibular third molars (M3M), including intra-operative failure, pain, infection, dry socket, inferior dental alveolar (IAN) and lingual nerve (LN) injuries and re-operation rates. METHODS: Retrospective analysis of 167 coronectomies completed between January 2017 to December 2022 was undertaken. RESULTS: The success of coronectomy was 93%. Intra-operative failure was reported to be 3.6% (n = 8). Complications accounted for pain (15%, n = 24), infection (9%, n = 15) and dry socket (3.6%, n = 6). Three patients required removal of M3M root at 3 months (n = 2) and 24 months (n = 1), accounting for 1.8% re-operation rate. A total of number of patients who suffered a nerve injury was 12; three of these were permanent (LN - 1.2%, n = 2; IAN - 0.6%, n = 1), nine were temporary (IAN - 1.2%; n = 2, LN - 2.4%; n = 4; site not specified - 1.8%, n = 3). No patients with intra-operative failure and re-operation suffered IAN or LN injury post-operatively. CONCLUSION: Coronectomy offers a successful strategy for management of high risk M3M. The treatment outcomes can be improved with careful case selection and adjusting surgical technique, including assessment of root morphology, incomplete crown sectioning technique and avoidance of lingual retraction. Reporting of coronectomy success as a factor of surgical outcome, presence or absence of permanent IAN injury, persistent symptoms or any other long-standing complications (such as LN injury), and the need for re-operation accounting for root migration status may be a useful tool to measure coronectomy outcomes.

Introduction Dental core training posts within oral and maxillofacial surgery (OMFS) units often include on-call provision. There is a lack of current data demonstrating the variation of dental core trainee (DCT) involvement in on-call. This variation may influence trainees' experience of training.Aim To examine the provision of on-call cover in OMFS units across the United Kingdom, including trainee involvement, supervision and training.Method Online surveys were distributed in August 2019 to all DCTs, educational supervisors (ESs) and training programme directors (TPDs) in OMFS units to understand trainee involvement in on-call provision, including levels of supervision and perceived educational benefit.Results In total, 167 trainees responded from 69 OMFS units. Responses were received from 102 ESs/TPDs. All trainees experienced on call, with over 75% covering night shifts. Trainees reported minimal difference between support within hours and out of hours (OOH). Qualitative data from trainees and supervisors highlighted the educational value of on-call within normal hours. However, limited supervised training opportunities were reported OOH.Conclusion This survey highlights the educational value of on-call within hours. The perceived level of support does not vary significantly between normal hours and OOH. Some concerns were expressed regarding OOH supervision and prolonged on-call periods.
RESUMEN
We present what is to the best of our knowledge the first reported case of first bite syndrome as a delayed complication of bimaxillary osteotomy.
