Abstract

OBJECTIVES

To evaluate the survival of root canal treated (RCT) teeth adjacent to an implant compared with that of RCT teeth of the same patient non-adjacent to an implant.

MATERIALS AND METHODS

RCT tooth of each patient adjacent to an implant were included in the test group. The control group consisted of another RCT tooth of the same patient; the control RCT tooth was not adjacent to an implant and selected to be of the same type of the RCT tooth in the test group. 72 teeth of 36 patients with at least 4-year follow-up were included. In addition to survival, other clinical and demographic parameters investigated were age, sex, tooth type and position, presence of a crown, presence of retreatment, presence of a post-core, presence of adjacent edentulous area, presence of implant-supported fixed prosthetic restoration on the antagonist tooth and periapical health status. Pearson Chi-Square and Fisher Exact tests were used to compare the test and the control groups with categorical variables (α=0.05). Survival curves were obtained by the Kaplan-Meier method, and the Log-rank test was performed to compare the survival probabilities (α=0.05).

RESULTS

No significant difference in survival rates was observed between the test and the control groups (p = 0.72). Similarly, no significant relationship was found between the investigated clinical variables and the survival rates of RCT teeth (p>0.05). Survival times differed depending on the presence of an adjacent edentulous area (p<0.001) and the periapical health status (p = 0.026).

CONCLUSIONS

RCT teeth with unhealed periapical tissues had a shorter cumulative survival time. Similarly, those adjacent to an edentulous area had shorter cumulative and complication-free survival times.

CLINICAL SIGNIFICANCE

This is the first study to determine the survival outcome of a RCT tooth adjacent to an implant compared to a non-adjacent one in the same patient. Being adjacent to an implant did not have a detrimental effect on the survival time and rate of RCT teeth.

摘要

目的

评估根管治疗（RCT）后与种植体相邻牙齿的生存率，并与同一患者中不与种植体相邻的RCT牙齿的生存率进行比较。

材料与方法

将每位患者中与种植体相邻的RCT牙齿纳入试验组。对照组由同一患者的另一颗RCT牙齿组成；对照RCT牙齿不与种植体相邻，且选择与试验组中的RCT牙齿类型相同。纳入了36例患者的72颗牙齿，随访时间至少4年。除了生存率外，还调查了其他临床和人口统计学参数，包括年龄、性别、牙齿类型和位置、是否有牙冠、是否进行过再治疗、是否有桩核、是否存在相邻无牙区、对颌牙是否有种植体支持的固定修复以及根尖周健康状况。采用Pearson卡方检验和Fisher精确检验对试验组和对照组的分类变量进行比较（α=0.05）。通过Kaplan-Meier方法获得生存曲线，并进行Log-rank检验以比较生存概率（α=0.05）。
