De Bruyn L, et al. - In this retrospective cohort study involving 1,682 individuals, mean age 31 years, who were referred to the University Hospitals Leuven, researchers identified and quantified indications for retaining third molars, or wisdom teeth. They identified eight reasons for retaining the third molars: risk of damaging adjacent structures, compromised health status, adequate space for eruption, third molar serves as abutment tooth, orthodontic reasons, eruption into proper occlusion, symptomless third molars in patients > 30 years old, and patient preference. For retaining third molar teeth, the most frequent reasons were: eruption into proper occlusion, patient preference, and symptomless third molars in patients > 30 years old. In the decision as to whether to retain the third molars, compromised health status and advanced age were often involved. One third of the patients referred were justified in retaining one or more third molars. Such findings may encourage a consensus statement's future development.
