Incidence and distribution of root canal treatment in the dentition among a Jordanian sub population

Abstract

Aim: To determine and compare the incidence of endodontically treated teeth in the maxilla and mandible, and to present the frequency of endodontic treatment for each tooth in the dentition in a group of the Jordanian population; then to compare these results with previously published surveys. Method: A total of 1,404 root canal treated teeth were examined clinically and radiographically. Results: Most teeth were treated in a one visit procedure (40.1%). The results showed that 77.7% of the treated teeth were in the maxilla and 22.3% were in the mandible. Posterior teeth accounted for 39.0% of all treated teeth, among which, 20.3% were molars. The most frequently treated tooth was the maxillary central incisor tooth (39.6%), with the maxillary lateral incisor second (10.1%). Furthermore, the maxillary incisors alone accounted for almost half (49.7%) of the cases. The maxillary first molar was the third most frequently treated tooth (8.2%) with the mandibular first molar at 7.5%.The lowest frequency of treatment was for mandibular lateral incisors and canines which made up only 1.1% and 1.9% respectively. Conclusion: Comparison with previously published surveys revealed a lower percentage of molar endodontics than in other surveys.
