| Summary | Study Title: Clinical Performance of Highly Viscous Glass Ionomer versus Bulk Fill Resin Composite Restorative Materials in Moderate Class II Cavities of Permanent Posterior Teeth: A 12-Month Randomized Clinical Study Study Design: Split-mouth, randomized clinical trial on 31 patients with at least two moderate Class II carious lesions in permanent posterior teeth. Each patient receives two restorations-bulk fill resin composite on one side and highly viscous glass ionomer (HVGIC) on the other. Aim: To compare the clinical performance of bulk fill resin composite and HVGIC restorations over 1 week (baseline), 6 months, and 12 months using the modified United States Public Health Services (USPHS) criteria. Primary Outcome: Marginal adaptation of the restorations Secondary Outcomes: 1. Anato |
