Abstract
Aim and objective: This randomized clinical trial aimed to evaluate the clinical performance of a bioactive restorative material vs a glass hybrid restorative material in posterior restorations in high caries risk patients. Materials and methods: High-risk caries patients with multiple posterior cavitated caries lesions were enrolled in this split-mouth clinical trial. Fifty randomly selected teeth received either a resin-modified glass ionomer bioactive resin-based composite [ACTIVA BioACTIVE-RESTORATIVE (Activa)] (n = 25) or a bulk-fill glass hybrid restorative [EQUIA Forte Fil (Equia)] (n = 25). Materials were applied according to the manufacturer's instructions. Two well-trained experienced blinded assessors evaluated the restorations at baseline, 6, and 12 months using FDI criteria for direct and indirect restorations. Results: The survival percentages for the intervention and comparator groups were 98% after 6 and 12 months. Regarding the primary outcome, no statistically significant difference was observed between the two groups. While for the secondary outcome, the color match parameter showed a significantly better score for Activa at baseline, 6, and 12 months. With respect to the anatomic form, Activa scored significantly better compared to Equia At 6 and 12 months (p < 0.001). Regarding functional properties, at baseline, no difference between the tested groups was observed for all functional parameters (p > 0.05). Furthermore, at 6 and 12 months, Activa scored significantly better for occlusal contour and wear compared to Equia (p < 0.001).
