Various irrigation techniques for cleansing the endodontic space have been proposed, and internal heating combined with ultrasonic activation (3D cleaning technique) is considered an effective technique. This prospective multicenter clinical study aims to evaluate healing rates for teeth after root canal treatment utilizing the 3D cleaning technique and to report predictive values for success.
Ninety patients referred for a root canal treatment were included. All enrolled patients were treated with the 3D cleaning protocol. Four endodontists performed the clinical procedures and follow-up evaluations. Preoperative, postoperative and follow-up data were gathered from the consented patients. Each patient was assessed for any clinical signs or symptoms. Afterwards, two trained, blinded, and independent evaluators scored the subject's periapical radiographs. This score was made by checking for the presence or absence of apical periodontitis using the periapical index (PAI). Then, the teeth were classified as healing or healed and were considered a success based on a cumulative success rate of healing. Statistical analysis was performed using the Fisher's exact test, Pearson correlation, and logistic regression analyses of the preoperative prognostic factors at a 0.05 significance level.
90 patients were evaluated at two years with a follow-up rate of 97.7%. The cumulative success rate of healing was 95.4%. Eight predicting aspects were identified by employing bivariate analyses. Then, using logistic analyses, the two prognostic significant variables directly correlated to healing were the preoperative presence of periapical index ( value = 0.016).
In this two-year clinical study, the cumulative success rate of healing was 95.4% when patients were treated with the 3D cleaning protocol.
已提出多种用于清洁根管系统的冲洗技术，内部加热联合超声激活（三维清洁技术）被认为是一种有效的技术。这项前瞻性多中心临床研究旨在评估使用三维清洁技术进行根管治疗后牙齿的愈合率，并报告成功的预测指标。
纳入90例因根管治疗前来就诊的患者。所有入组患者均采用三维清洁方案进行治疗。四名牙髓病医生进行临床操作和随访评估。从签署知情同意书的患者中收集术前、术后及随访数据。对每位患者评估有无任何临床体征或症状。之后，两名经过培训、不知情且独立的评估人员对受试者的根尖X线片进行评分。该评分通过使用根尖指数（PAI）检查根尖周炎的有无来进行。然后，将牙齿分类为愈合或已愈合，并根据累计愈合成功率判定为成功。使用Fisher精确检验、Pearson相关性分析以及对术前预后因素进行显著性水平为0.05的逻辑回归分析。
对90例患者进行了两年的评估，随访率为97.7%。累计愈合成功率为95.4%。通过双变量分析确定了八个预测因素。然后，通过逻辑分析，与愈合直接相关的两个预后显著变量是术前根尖指数的存在情况（值 = 0.016）。
在这项为期两年的临床研究中，当患者采用三维清洁方案进行治疗时，累计愈合成功率为95.4%。
