Surgeons’ ability to estimate third molar (M3) extraction difficulty is influenced by patient demographics and anatomy, not surgical experience or radiographic findings.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Surgical Education
  • Clinical Decision-Making

Background:

  • Accurate estimation of third molar (M3) extraction difficulty is crucial for surgical planning and patient outcomes.
  • Variability in surgical experience and patient-specific factors may influence difficulty assessments.

Purpose of the Study:

  • To evaluate surgeons' accuracy in predicting M3 extraction difficulty.
  • To identify demographic and anatomic predictors of estimation errors.

Main Methods:

  • Prospective cohort study involving 15 surgeons and 82 patients undergoing 250 M3 extractions.
  • Surgeons estimated difficulty using a visual analogue scale preoperatively and postoperatively.
  • Error was defined as the difference between preoperative and postoperative difficulty estimates.

Main Results:

  • The mean absolute error in difficulty estimation was 15.7 mm.
  • Demographic variables (age, gender, ethnicity, snoring) and anatomic factors (cheek flexibility, mouth opening) were significantly associated with estimation errors (P <= .05).
  • Surgical experience and radiographic variables showed minimal association with estimation errors.

Conclusions:

  • Surgeons' difficulty estimations for M3 extractions are more dependent on patient-specific demographic and anatomic characteristics than on their own surgical experience or imaging data.
  • Understanding these influencing factors can help improve preoperative assessments and surgical planning for third molar extractions.
