Chronic root fractures are a relative frequent dental condition, occurring both in vital teeth and in teeth with root canal treatment, with a difficult and frustrating diagnosis. Two clinical forms are described: crown-root fractures with crown origin and vertical root fractures with root origin. The aim of the study was to determine the prevalence of the root fractured extracted teeth in two dental clinics with different profile [oral rehabilitation (OR) and endodontics (E)] and to present some particular aspects of the root fractures. A retrospective study over a period of five years was performed to determine the number of extracted teeth and the motives for extraction. For root fractured extracted teeth were noted: fracture type, tooth vitality, restoration type. Although the number of the patients with tooth extractions in the five years period was significantly higher in OR clinic than in E clinic, the number of tooth extractions was almost similar. Most of the teeth (70.6%) were extracted for caries complications. The prevalence of the root fractured extracted teeth was 17.93%. In OR clinic, women had more root fractured extracted teeth compared with E clinic, where the number of root fractured extracted teeth was higher in men. Most extracted teeth for root fracture were teeth with prosthetic restorations followed by teeth with root canal treatment and dental fillings. The most extracted teeth for root fracture were maxillary premolars, almost similar for both sexes, followed by mandibular molars. The teeth with least extractions for root fractures were mandibular incisors and mandibular canine.
