简要总结
The aim of the study is to compare the effect of high intensity light cure (2200 mw/cm2) for 1 second with low intensity light cure (1200 mw/cm2) for 20 seconds on the clinical performance of bulk fill resin composite restorations in compound Class II cavities of posterior teeth
详细描述
The prepared cavities will be conditioned with 35% phosphoric acid gel for15 seconds, then will be rinsed and dried with compressed air. Then application of universal adhesive system to all cavity with bond brush then light cured for 10 seconds using LED light curing unit (1200 mw/cm2). Extra-Fill bulk fill resin composite will be applied in onebulk increment and will be light polymerized for 1 second using (LED) light curing unit (2200 mw/cm2).for intervention group Extra-Fill bulk fill resin composite will be applied in one bulk increment and will be light polymerized for 20 seconds using (LED) light curing unit (1200 mw/cm2) fot control group

主要结局
Clinical performance
时间窗: Change from the baseline at 6 months and12 months
Clinical performance of bulk fill resin composite restorations will be evaluated by modified USPHS Criteria includes: * Marginal Discoloration * Marginal adaptation * Secondary caries * Postoperative sensitivity For each criteria one score will be chosen from 3 scores (Alpha,Bravo\&Charlie).
