Stepwise regression analysis of cure depths of light curing composite resin / 实用口腔医学杂志

ABSTRACT

Objective: To analyze the effect of different treating factors on cure depths of light curing composite resin, and discuss the relationship between different treating factors and cure depths. Methods:192 samples were designed with factorial experiment. The whole samples were scanned by Planmeca ProMax panoramic X-ray unit and cure depths were measured. The data was statistically analyzed by SPSS 11.5 software package for t test and stepwise regression analysis. Results:There were significant differences among different light curing units, irradiation distances and cure time(P
