To evaluate the outcome of teeth filled with a single cone technique and a premixed bioceramic sealer at 3 years of follow-up.
Healthy patients were consecutively treated by a cohort of postgraduate operators. Root canal filling procedures were performed with NiTi rotary instrumentation, while non-surgical retreatments were performed using NiTi reciprocating instruments. Root canal filling procedures were performed using Ceraseal and the single cone technique. Post-endodontic restorations were performed after 15 days. Provisional and definitive crowns were positioned in case of non-sufficient coronal structure. Periapical radiographs were made before treatment, after filling, and at each follow-up visit (6, 12, 24 and 36 months). The periapical Index (PAI) was used to assess the presence of periapical lesions and their modifications over time. Success (absence of periapical radiolucency, PAI <3) and survival rates were evaluated. The presence of apical extrusion was also radiographically assessed. Linear regression analysis was used to investigate changes in mean PAI scores, and logistic regression analysis was used to investigate changes in the percentage of healed cases. All analyses were replicated using two distinct approaches: per protocol (PP) (treatments who completed the follow-up) and intention to treat (ITT) (all root canal treatments). A significance level of 5% was used for all statistical tests (α=0.05).
Fifty-eight endodontic treatments in 52 patients were performed (ITT). Thirty-eight endodontic treatments in 33 patients completed the 3 years of follow-up with a survival rate of 92.7%. The success rate was 85.4% (PP).
The use of Ceraseal associated with the single cone technique was safe in maintaining endodontically affected teeth. (EEJ-2024-01-02).
评估采用单锥技术和预混生物陶瓷封闭剂充填牙齿3年随访的结果。
由一组研究生操作人员连续治疗健康患者。采用镍钛旋转器械进行根管充填操作，而采用镍钛往复器械进行非手术再治疗。使用Ceraseal和单锥技术进行根管充填操作。根管治疗后15天进行根管后修复。如果冠部结构不足，则放置临时冠和永久冠。在治疗前、充填后以及每次随访（6、12、24和36个月）时拍摄根尖片。根尖指数（PAI）用于评估根尖周病变的存在及其随时间的变化。评估成功率（无根尖周透射影，PAI<3）和生存率。还通过影像学评估根尖挤出的情况。采用线性回归分析研究平均PAI评分的变化，采用逻辑回归分析研究愈合病例百分比的变化。所有分析均使用两种不同方法重复进行：按方案（PP）（完成随访的治疗）和意向性治疗（ITT）（所有根管治疗）。所有统计检验的显著性水平均为5%（α=0.05）。
对52例患者进行了58次根管治疗（ITT）。33例患者中的38次根管治疗完成了3年随访，生存率为92.7%。成功率为85.4%（PP）。
Ceraseal与单锥技术联合使用在维持根管治疗患牙方面是安全的。（EEJ - 2024 - 01 - 02）
