There is not enough evidence to support the bevelled technique over non-bevelled for NCCLs over longer periods of time .
OBJECTIVES To identify if enamel bevelling , compared to no treatment , improves the retention rates and marginal discolouration of cervical composite restorations in non-carious cervical lesions ( NCCLs ) of adult patients , through a systematic review of the literature and meta- analysis .
Influence of acid etching and enamel beveling on the 6-month clinical performance of a self-etch dentin adhesive.
This study tested the hypothesis that beveling and /or etching enamel does not affect the 6-month clinical performance of the self-etch adhesive Clearfil SE Bond in class V noncarious lesions . With Institutional Review Board approval , 34 patients were enrolled in this study . A total of 120 noncarious cervical lesions were selected and assigned to 4 groups : ( 1 ) Clearfil SE Bond was applied without any cavity preparation ; ( 2 ) After the enamel was beveled , Clearfil SE Bond was applied ; ( 3 ) After the enamel was etched for 15 seconds with 35 % phosphoric acid , Clearfil SE Bond was applied ; ( 4 ) After the enamel was beveled and etched with 35 % phosphoric acid for 15 seconds , Clearfil SE Bond was applied . A microfilled composite resin was used for all restorations . Six months after initial placement , 120 restorations ( a 100 % recall rate ) were re-evaluated . Retention rates at 6 months were 100 % for all groups . Sensitivity to air improved from baseline to 6 months , but the overall difference was not statistically significant . The 6-month retention rate of the self etch dentin adhesive system Clearfil SE Bond was not improved by enamel beveling or by enamel etching . For the self-etch material Clearfil SE Bond , instrumentation or etching of enamel may not be critical for its clinical performance at 6 months
