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.
A total of 1,404 root canal treated teeth were examined clinically and radiographically.
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.
Comparison with previously published surveys revealed a lower percentage of molar endodontics than in other surveys.
确定并比较上颌牙和下颌牙根管治疗的发生率，呈现一组约旦人群中牙列中每颗牙齿的根管治疗频率；然后将这些结果与之前发表的调查进行比较。
对总共1404颗根管治疗后的牙齿进行了临床和影像学检查。
大多数牙齿采用一次就诊治疗（40.1%）。结果显示，77.7%的治疗牙齿在上颌，22.3%在下颌。后牙占所有治疗牙齿的39.0%，其中20.3%为磨牙。治疗频率最高的牙齿是上颌中切牙（39.6%），其次是上颌侧切牙（10.1%）。此外，仅上颌切牙就占了近一半（49.7%）的病例。上颌第一磨牙是治疗频率第三高的牙齿（8.2%），下颌第一磨牙为7.5%。治疗频率最低的是下颌侧切牙和尖牙，分别仅占1.1%和1.9%。
与之前发表的调查相比，磨牙根管治疗的百分比更低。
