    Abstract:
    The purpose of the study is to collect information on the reasons given by dentists, randomly selected from the Italian Dental and Maxillo-Facial Association's, for extracting permanent teeth in Italy. From the 164 dentists responding, 1056 teeth in 839 patients were extracted during two weeks of working activity. More than two-thirds of the teeth were extracted for dental caries (34.4%) and periodontal disease (33.1%). The mean number of teeth extracted per patient showed a significant increasing trend with increasing age, being 1.09 in those from 16 to 39 yr, 1.25 in the 40-59-yr-old group, to 1.54 in those over 59 yr of age (F = 21.44; P < 0.0001). The third molar was the most frequently extracted tooth and 41.3% were removed due to impaction reasons, in particular from the mandible. The first and second molars and the premolars were extracted most often because of caries; more than half of the incisors and the canines were extracted for periodontal reasons; the majority of the teeth removed for prosthetic reasons, 57.1%, were incisors and canines, especially in the mandible; of the teeth extracted for orthodontic reasons, 47.4% were first and second premolars. The prevalence of subjects with at least one tooth extracted for dental caries and for orthodontic reasons were respectively significantly higher in the irregular than the regular attenders (chi-square = 46.55; P < 0.0001), and in the regular than the irregular dental attenders (chi-square = 63.12; P < 0.0001). Dental practitioners should promote targeted initiatives for prevention and treatment of diseases in order to reduce in particular the incidence of tooth extraction because of caries and periodontal disease.
