Clinical Performance Of Conserved Chalky White Demineralized Enamel Cavity Margins Versus Totally Removed Carious Margins In Class V Cavities Restored With Composite Resin

Class V Dental Caries

This study aims to compare the clinical performance of conserved chalky white demineralized enamel margins with total removal of demineralized enamel margins in class v cavities restored with composite in patients with acute carious cervical lesions

With limited evidence-based information about the clinical performance of conserved white chalky enamel margins in class v .it is beneficial to compare the newly concept of preserved the white chalky deminerlized enamel margins using a randomized clinical trial to test the null hypothesis that this new concept has the same clinical performance as total removal of demineralized enamel margins in class v cavities restored with composite in patients with acute carious cervical lesions .The comparator will be the concept of total removal of demineralized enamel margins in class v cavities restored with composite Patients are selected according to the eligibility criteria, Local anesthesia will be administered and the operative field will be isolated before starting the restorative procedure. For the comparator group, standard class V cavities will be prepared at labial surface with totally removed carious enamel margins. For interventional group, class V cavity prepared at labial surface with preserved the chalky demineralized enamel margins then applications of remineralizing agent(MI paste plus) before the application of resin composite restoration. Local anesthesia will be administered and the operative field will be isolated before starting the restorative procedure. For control group, standard class V cavities will be prepared at labial surface with totally removed carious enamel margins. For experimental group, class V cavity prepared at labial surface with preserved the chalky demineralized enamel margins then applications of remineralizing agent(MI paste plus) before the application of resin composite restoration. both cavities groups restored with resin composite restorations. The restorations are assessed using the modified USPHS criteria at the time intervals stated in the outcome measures
