title: Mandibular third molars: oral surgeons' assessment of the indications for removal.
abstract: The aim was to examine oral surgeons' assessment of the indications for removal of mandibular third molars. Questionnaires were distributed to seven oral and maxillofacial surgery clinics. The oral surgeons were asked to record whether or not there was associated disease. Three other factors were recorded: patient's age, and angular position and extent of eruption of the molars. The strength of the indication for removal was rated on a visual analogue scale (VAS) where 0= weakest and 100= strongest indication for removal. The results were based on data from 666 molars: 118 (18%) had no disease, 465 (70%) had one associated disease, 77 (11%) had two and 6 (1%) had three. The indication for removal as expressed by the mean VAS for molars with no disease was assessed to be weaker (P<0.05) than that for molars with one, two, or three diseases. The only factor that influenced the indication for removal in molars with no disease was the patient's age.
