Abstract
Objective:To assess the effect of the prepared surface and the finish line of the preparations under assis⁃ting the dental magnifying glass by the assessment software(PrepCheck 2�0)of CEREC® chair⁃side computer aided design ( CAD) system. Methods:Forty junior dental students participatedin training about the using of the magnifying glass were se⁃lected randomly. Each student had an obligation to prepare 2 tooth before and after training,respectively. The smoothness of prepared surface and the continuity of the finish line were recorded by using PrepCheck 2�0 software. The statistical data was analyzed in order to compared the discrepancy. Results:The application of dental magnifier in tooth preparation could effec⁃tively improve the continuity of finish lines and decrease the sharp edges on the prepared surfaces(P<0�05). Conclusion:The dental magnifier can effectively improve the accuracy of tooth preparation in dental operation procedures.关键词
