Introduction: The purpose of this prospective study was to analyze the factors related to extraction of endodontically treated teeth. Methods: One hundred nineteen cases of extraction of endodontically treated teeth were consecutively reviewed, and the following items were recorded: type of tooth; presence and type of coronal restoration; motive of consultation; reasons for extraction; patient’s age, gender, level of education; smoking status. Association between factors was inves- tigated with c2 analysis. Results: Dental pain was the main motive for consultation (68.9%). The teeth most extracted were mandibular molars (51.3%), followed by maxillary molars (16.1%). First molars were the most frequently extracted (29.4%). Ninety-one teeth (76.5%) were restored coronally with or without post, and crowned teeth represented 5.9% of the sample. The reasons for extraction were periodontal disease (40.3%), endodontic failure (19.3%), vertical root frac- ture (13.4%), nonrestorable cuspid and crown fracture (15.1%), nonrestorable caries (5.2%), iatrogenic perfo- rations and stripping (4.2%), and prosthetic (0.8%). Analysis between gender, smoking status, and educa- tion level showed no significant difference for reasons of extraction (P = .33 and .34). Conclusions: The mandibular first molar without crown was the most frequently extracted tooth. The main reasons for extrac- tions were periodontal disease, endodontic failure, and nonrestorable tooth damage caused by fracture or caries.
