title: Accidents and complications associated to third molar surgeries performed by dentistry students.
abstract: OBJECTIVE
  The aim of this work is to demonstrate the accidents and complications rates on third molars surgeries performed by senior dentistry students.
  
  
  METHODS
  A retrospective study of 122 patient charts submitted to third molars surgeries was done. Patient age, gender, dental in arch position, and accidents/complications were considered with the charts presenting incomplete dates being excluded from the study. After all, 88 patients (210 surgeries) were included.
  
  
  RESULTS
  The majority of the patients were female (70.4 %), with the average age of 24 years. Mandibular molars represented more than half of the surgical procedures (56.2 %), with teeth at vertical position the most found (60.3 %). The cases of accidents and complications totalized 10.4 % of all performed procedures, being hemorrhage (1.9 %), root fractures (1.9 %), and maxillary tuberosity fracture (1.9 %) the most found. Suture dehiscence (1.4 %), dry socket (1.4 %), oroantral communications (0.9 %), paresthesia (0.9 %), and infection (0.4 %) were also observed.
  
  
  CONCLUSIONS
  Surgeons' inexperience was not considered a determinant factor to modify the rates of accidents and complications at third molars surgeries when compared to previous works developed by experienced surgeons. It is important to highlight the necessity of the students' knowledge of the most adequate treatments of each of the accidents and complications.
