Factors influencing the prophylactic removal of asymptomatic impacted lower third molars.
The aim of this study was to analyse factors indicating prophylactic removal of impacted lower third molars, and how they, and possibly surgeon experience, influence the therapeutic decision-making process. A descriptive observational study was made of 40 asymptomatic impacted lower third molars. Orthopantomographs were scanned and presented to four professionals with different degrees of surgical experience. The examiners received information relating to patient age and sex, molar inclination and degree of impaction, and expressed their opinion on the necessity for teeth removal. There was a statistically significant relationship between examiner decision and the estimated probability of pathology if the molars were not removed (P<0.05). The degree of influence on the decision to extract was in decreasing order: estimated risk of complications, inclination of molar, age, degree of impaction and patient sex. No statistically significant differences (P>0.05) were observed between residents and trainers in terms of the decision to remove or estimated risk of complications. The management approach adopted by oral surgeons regarding the removal of asymptomatic impacted lower third molars depends upon the perceived risk of complications if such teeth are not removed, other factors being secondary. The surgical experience of the professional does not seem to influence treatment decision.
