Judgement of removal of asymptomatic mandibular third molars: influence of position, degree of impaction, and patient's age.
Our aim was to study general dental practitioners' (GDPs') and oral surgeons' judgement of the need for removal of asymptomatic mandibular third molars, described by three cues. The judges were also asked to estimate the development of pathologic conditions. There was considerable variance with regard to the individual judgements. As a group, GDPs estimated the need for removal to be higher for patients less than 40 years than those more than 40 years old. The oral surgeons estimated the need to differ for three different age groups. The GDPs estimated the need to be highest for distoangular molars and lowest for vertical molars, whereas the oral surgeons estimated these positions to be equal. Molars partially covered by soft tissue were given the highest priority for removal by both groups of judges. The mean proportion of variation explained by the three cues was high, except for tumor development, indicating that the judges used the cues and the combination of them to a great extent in their judgement of the risk for development of pathologic conditions.
