Evaluation of Marginal Integrity Using Bioactive Cement Incementation of Indirect Composite Blocks

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to evaluate of marginal integrity of indirect composite restoration after cementation by a bioactive cement in comparison to dual cure resin cement using Modified USPHS criteria

Detailed Description
-----------------
The study will be conducted in Conservative Dentistry Department, Faculty of Dentistry, Cairo University, The operator in charge will be: Mohamed Sherif . The researcher will bear ultimate responsibility for all activities associated with the conduct of a research project including recruitment of patients, explaining and performing the procedures to them,A total of 36 volunteer patients with Patients with badly broken vital teeth with minimum of two remaining walls. Patients will be randomly divided into two groups according to type of cement (S) where in group S1, Restoration will be cemented with resin cement ; while group S2,Restoration will be cemented with active cement. Each restoration will be assessed after three, six months and one year using modified USPH Criteria Marginal Discoloration, Recurrent Caries and Marginal Chipping with scale of Alpha and non alpha
