Practice on establishing simple evaluation standards for access preparation of molar / 中华医学教育探索杂志

ABSTRACT

Objective:To establish simple and accurate evaluation standards for access preparation of molar and verify its reliability.Methods:9 undergraduate students who had entered the intership for one month prepared access of molars in vitro. 10 dentists specialized in endodontics for over 5 to 15 years evaluated the molars according to the evaluation standards. Intraclass correlation coefficient of the results was analyzed by SPSS statistics. Results:The intraclass correlation co-efficient of the evaluation given by 10 endodontists was 0.739 ( P=0.000), which had statistical significance. The result was between 0.61 and 0.80, meaning the evaluation standards were moderately reliable and applicable among different observers. Conclusions:The evaluation standards proposed in this study are reliable and has not been influenced by the clinical experience of observers. And it is worth further exploration and promotion.
