title: High weight standard and removal of third molars: a prospective randomized study.
abstract: OBJECTIVE
  Compare the degree of exposure to adverse events during the removal of third molars between 2 groups of patients.
  
  
  METHODS
  Researchers designed and implemented a prospective randomized study. The study consisted of overweight and normal-weight patients subjected to the surgical removal of impacted lower third molars. A wide range of predictor variables was registered in the preoperative phase. Statistical calculations were computed.
  
  
  RESULTS
  Five hundred sixty surgeries were performed involving 2 groups (1:1). Adverse events were found in 29.3% of surgeries in overweight patients. The same procedures performed on normal-weight patients resulted in a complication rate of 10.7%. Predictor variables significant to these events were detected.
  
  
  CONCLUSIONS
  Overweight patients have 3 times greater risk of experiencing morbidities during the removal of lower third molars compared with patients of normal weight. Our findings have important implications for public health, given the exorbitant growth in the population of patients with high standard weight.
