title: Compliance of postoperative instructions following the surgical extraction of impacted lower third molars: a randomized clinical trial.
abstract: OBJECTIVE
  The understanding and adherence to postoperative care instructions are factors that influence the recuperation process after any surgical procedure. The aim of this study was to determine the percentage of patients who strictly follow the postoperative instructions after the extraction of an impacted lower third molar in relation to sociocultural level, preoperative anxiety scores and how postoperative information is provided to the patient.
  
  
  METHODS
  Patients were randomly assigned to one of three different test groups according to how the postoperative instructions were presented: verbal, written and a group that received additional information. Before surgery, patients were required to complete the Corah Dental Anxiety Scale and personal information (age, gender and educational level) was also collected. P <0.05 was considered significant. Patients were surveyed a week after surgery regarding their adherence to postoperative instructions.
  
  
  RESULTS
  84 patients (45 women and 39 men with an average of 28.23 ± 7.41 years) completed the study. There were no statistically significant differences regarding adherence of postoperative care instructions depending on the manner of instruction presentation, preoperative anxiety level and sociocultural level (p> 0.05). Quitting smoking or drinking of alcoholic/carbonated beverages were the main influential factors for the lack of adherence to postoperative care instructions during the week after surgery.
  
  
  CONCLUSIONS
  Presentation of postoperative instructions, preoperative anxiety scores and sociocultural level do not appear to be key factors that promote the adherence to postoperative instructions.
