Abstract

OBJECTIVES

The objective of this study was to evaluate radiographically the technical standard of root canal treatment performed by undergraduate dental students at the Dental Teaching Center in Jordan.

METHODS

A random sample of 8500 records of dental patients was examined. A total of 542 endodontically treated teeth with 912 roots were evaluated. Periapical radiographs were used to assess the technical quality of the root canal filling. The length of each root canal filling was categorized as acceptable, short and overfilled based on their relationship with the radiographic apex. Density and taper of filling was evaluated based on the presence of voids and the uniform tapering of the filling, respectively. Chi-square analysis was used to determine statistically significant differences between adequacy of root canal filling in each group of teeth according to its location, position and curvature.

RESULTS

Sixty-one percent of roots had fillings of acceptable length, while 34.5% were short and 4.2% were overfilled. The root canal fillings of 47.4% were found to be adequate. Adequate fillings were found more in maxillary than mandibular teeth (P < 0.005), anterior compared to posterior teeth (P < 0.05) and in straight canals compared to curved canals (P < 0.001).

CONCLUSION

The technical quality of root canal treatment performed by undergraduate dental students using step-back preparation and lateral condensation was found to be less than 50%. Review of the endodontic curriculum requirements, specialized clinical supervision and increasing the time of training at the preclinical and clinical levels should improve this quality.

摘要

目的

本研究的目的是通过影像学评估约旦牙科教学中心本科牙科学生进行根管治疗的技术水平。

方法

对8500例牙科患者的记录进行随机抽样检查。共评估了542颗接受牙髓治疗的牙齿的912个牙根。根尖片用于评估根管充填的技术质量。根据每个根管充填物与影像学根尖的关系，将其长度分为可接受、短和超充三类。分别根据有无空隙和充填物的均匀锥度评估充填物的密度和锥度。采用卡方分析确定根据牙齿位置、部位和弯曲度分组的每组牙齿根管充填充足性之间的统计学显著差异。
