目的：本研究的目的是评估风险因素影响的成功率，无论是在年轻人和成人population.Methods：牙髓切除术（n = 273）进行了分析，由一个单一的牙髓专家，成功率的数据收集。此外，还记录了可能的解释变量，如：年龄、性别、临床结果（牙齿、活髓切断术后的修复类型）、影像学结果（牙本质桥形成）和全身状况。随访时间从1年到29年不等，Kaplan-Meier生存曲线和考克斯regression.Results分析结果：活髓切断术时的年龄范围为8岁到79岁，并没有影响成功率（p = 0.35）。牙本质桥的形成具有较强的保护作用（危险比HR = 0.16，p < 0.001）。活髓切断术后的修复冠修复失败率最低，与修复体相比，银汞合金并没有显著增加失败的风险。活髓切断术后树脂复合材料修复增加了263%的失败风险（HR = 3.63，p < 0.001）。结论：本研究可以推断，活髓切断术可能是一种成功的治疗方法，在任何年龄，而不仅仅是年轻的恒牙。还可以得出结论，在活髓切断术后使用直接复合漂白与更高的失败率相关。(C)2015爱思唯尔有限公司版权所有。
Objectives: The aim of the present study is to evaluate risk factors influencing the success rates of pulpotomies both in young and adult populations.Methods: Pulpotomies (n = 273) performed by a single endodontic specialist were analyzed, and data on success rates were collected. Additionally, possible explanatory variables were noted such as: age, gender, clinical findings (teeth, type of restoration after pulpotomy), radiographic findings (dentin bridge formation) and systemic conditions. The follow-up period varied from 1 to 29 years, and the results were analyzed by Kaplan-Meier survival curves and also by Cox regression.Results: Age at the time of pulpotomy ranged from 8 to 79 and had not influenced the success rates (p = 0.35). The formation of dentin bridge had a strong protective effect (hazard ratio-HR = 0.16, p < 0.001). The prosthetic crown restorations following pulpotomy had the smallest failure rate, and amalgam has not increased the risk of failure significantly in relation to prosthesis. Resin composite restorations following pulpotomy increased in 263% the risk of failure (HR = 3.63, p < 0.001).Conclusion: This study allowed inferences that pulpotomy may be a successful treatment at any age, and not only for young permanent teeth. It was also possible to conclude that the use of direct composite restorations following pulpotomies is associated with higher failure rates. (C) 2015 Elsevier Ltd. All rights reserved.
