Abstract

AIM

To evaluate the current technical quality of root canal treatment (RCT) in Taiwan.

METHODOLOGY

A total of 1085 RCT cases, randomly selected from a large sample and representative of the Taiwanese population from April to September 2000, were evaluated by eight endodontic specialists. The qualitative evaluation of RCT cases was based on two variables: length of the root filling and density of the obturation. A root canal with both adequate filling length (the apical termination of the root filling within 2 mm of the radiographic apex) and complete obturation (no lateral or apical canal lumen visible in the apical one-third of the root canal) was defined as having good-quality endodontic work (GQEW). A tooth was defined as having a GQEW when all its canals were categorized as GQEW.

RESULTS

From a total of 1867 root canals, overfilling occurred in 235 (12.6%), adequate filling length in 1152 (61.7%), underfilling in 466 (25.0%) and no filling in 12 (0.6%). Of the 1867 root canals, 710 (38.0%) demonstrated complete obturation and 1157 (62%) demonstrated incomplete obturation. GQEW was found in 650 (34.8%) root canals and 329 (30.3%) teeth. The percentage of teeth with GQEW in hospital cases (38.1%) was significantly greater (P < 0.001) than that in private clinic cases (24.3%). In addition, the frequency of teeth with GQEW in the anterior teeth (40.4%) or in the premolars (33%) was significantly greater (P < 0.001) than that in the molars (18.4%).

CONCLUSIONS

Approximately 70% of the teeth receiving RCT in Taiwan were either of inadequate filling length or sealing density.

摘要

目的

评估台湾地区目前根管治疗（RCT）的技术质量。

方法

2000年4月至9月期间，从大量样本中随机选取1085例具有台湾地区人群代表性的RCT病例，由八位牙髓病专家进行评估。RCT病例的定性评估基于两个变量：根充长度和充填密度。根充长度足够（根充物根尖端位于X线根尖2mm范围内）且充填完整（根管根尖三分之一处无侧支或根尖管腔可见）的根管被定义为根管治疗质量良好（GQEW）。当一颗牙齿的所有根管都被归类为GQEW时，该牙齿被定义为具有GQEW。

结果

在总共1867个根管中，超充的有235个（12.6%），根充长度足够的有1152个（61.7%），欠充的有466个（25.0%），未充填的有12个（0.6%）。在1867个根管中，710个（38.0%）显示充填完整，1157个（62%）显示充填不完整。650个（34.8%）根管和329颗（30.3%）牙齿具有GQEW。医院病例中具有GQEW的牙齿百分比（38.1%）显著高于私人诊所病例（24.3%）（P<0.001）。此外，前牙（40.4%）或前磨牙（33%）中具有GQEW的牙齿频率显著高于磨牙（18.4%）（P<0.001）。
