Abstract:
:The aim was to study how three cues (patient's age and angular position and degree of impaction of the molar) were distributed among removed mandibular third molars associated with pathologic conditions and to compare these results with dentists' treatment decisions in another group of molars consisting of asymptomatic mandibular third molars, as mediated by the same cues. The overall agreement was fairly high between the dentists' treatment decisions and the removal rate among the molars subjected to removal. Thus, molars partially covered by soft tissue in patients aged 19 to 40 years had a high removal rate, and molars totally covered by bone tissue had the lowest removal rate in accordance with the dentists' treatment decisions. There were some exceptions. For example, molars partially covered by soft tissue in horizontal and mesioangular positions were rated higher by the dentists than the removal rates indicated. Distoangular molars in patients aged 26 to 40 years had the highest removal rate but a considerably lower order according to the dentists' decisions. Scientific evidence indicates that molars in mesioangular and horizontal positions present a low risk and molars in distoangular position present the highest risk of developing pathologic conditions, compared with other angular positions.
