The aims of this study were to evaluate the clinical outcomes of root canal treatments performed by final-year students in the Dental School of Piracicaba, State University of Campinas, SP, Brazil, during the year 2000 and to evaluate the success rate of these treatments at follow-ups conducted one and three years later (2001-03). All 579 endodontic treatments performed by final-year students were selected for this investigation. Detailed personal and dental history was obtained from the patient's records. Clinical and radiographic follow-up examinations were performed. For 78.8 percent of the cases, dental caries was recorded as the cause for performing endodontic treatment; for 8.8 percent, prosthetic reasons were given; and for 12.4 percent, failure of the endodontic treatment was the reason. The largest percentage (30.7 percent) of recalled patients was examined after one year; the success rate at this follow-up evaluation ranged from 83 percent to 96 percent depending on the pulp status prior to the root canal treatment. After three years, only 8 percent of treated patients returned; assessment for them revealed a 75.5 percent success rate. Dental caries is still the main reason for endodontic treatment. This level of success of the root canal treatment in a Brazilian dental school is similar to other reports in the literature.
本研究的目的是评估巴西圣保罗州坎皮纳斯州立大学皮拉西卡巴牙科学院的最后一年学生在2000年进行的根管治疗的临床结果，并评估在一年和三年后（2001 - 2003年）进行的随访中这些治疗的成功率。本次调查选取了最后一年学生进行的所有579例牙髓病治疗病例。从患者记录中获取详细的个人和牙科病史。进行了临床和影像学随访检查。在78.8%的病例中，记录龋齿为进行根管治疗的原因；8.8%的病例是出于修复原因；12.4%的病例是根管治疗失败为原因。召回患者中最大比例（30.7%）在一年后接受检查；根据根管治疗前的牙髓状况，此次随访评估的成功率在83%至96%之间。三年后，只有8%的接受治疗的患者回来；对他们的评估显示成功率为75.5%。龋齿仍然是根管治疗的主要原因。巴西一所牙科学院根管治疗的这一成功率水平与文献中的其他报告相似。
