To assess the 6- to 24-month outcome of endodontic treatments performed, by one specialist, and to identify prognostic factors that may influence initial endodontic treatment outcome (IETO).
One hundred and forty-six patients out of 163 were included. A number of 201 teeth were endodontically treated, and an overall number of 408 canals were obturated. Of these, 165 teeth received initial endodontic treatment (IET). The criteria of the European Society of Endodontology were used to assess the IETO. The level of significance was set at < 0.05%.
Apical periodontitis (AP) was present in 42.5% of all cases, with a PAI >3 in 28.5%. The success rate (SR) was 91.5%. It was significantly higher in vital teeth (97%) than in devital teeth (87.7%) (=0.04); however, a lower SR was recorded in teeth with AP (=0.02). The lesion healed in 60 teeth (85.7%), decreased in size in 4 teeth (5.7%), and increased in size in 6 teeth (8.5%). A higher SR was obtained when a permanent restoration was present (94%) than absent (68.7%) (=0.005).
Within the limitations of the study, pulp and periapical status and permanent restoration are found to be strong outcome predictors.
评估由一位专科医生进行的根管治疗6至24个月的疗效，并确定可能影响初始根管治疗结果（IETO）的预后因素。
163例患者中有146例被纳入研究。共对201颗牙齿进行了根管治疗，总计充填了408个根管。其中，165颗牙齿接受了初始根管治疗（IET）。采用欧洲牙髓病学会的标准评估IETO。显著性水平设定为<0.05%。
所有病例中根尖周炎（AP）的发生率为42.5%，PAI>3的发生率为28.5%。成功率（SR）为91.5%。活髓牙的成功率（97%）显著高于死髓牙（87.7%）（P=0.04）；然而，有AP的牙齿成功率较低（P=0.02）。60颗牙齿（85.7%）的病变愈合，4颗牙齿（5.7%）的病变大小减小，6颗牙齿（8.5%）的病变大小增大。存在永久修复体时的成功率（94%）高于不存在时（68.7%）（P=0.005）。
在本研究的局限性范围内，牙髓和根尖周状况以及永久修复体是强有力的疗效预测指标。
