Clinical evaluation of bioactive composite resin in class V lesions in high-risk caries patients: A randomized...

Recurrent caries at tooth-restoration interfaces remains a primary reason for restoration replacement. The challenge is developing biomaterials that prevent demineralization or promote remineralization. The study aimed to clinically evaluate and compare bioactive composite resin (CR), Predicta Bioactive Bulk, and nonbioactive CR in class V lesions of high-risk caries patients using the FDI criteria.

Twenty high caries risk adult patients with bilaterally symmetrical posterior buccal caries were selected. Restorations with either Predicta Bioactive composite or nonbioactive composite were undertaken and recalled for clinical evaluation at baseline (1 month), 3, 6, and 12 months using the FDI criteria. The data were analyzed using the SPSS software (Windows Version 22.0, Released 2013). Mean, standard deviation, frequency, proportions, Chi-square test, Cochran's Q test, and McNemar's post hoc test were assessed at P < 0.05 significance.

There were no statistically significant differences in the clinical performance of bioactive and nonbioactive composites in terms of marginal staining, fracture and retention, marginal adaptation, and recurrence of initial pathology.

Predicta Bioactive Bulk and 3M™ Filtek™ Bulk Fill Posterior Restorative demonstrated equivalent effectiveness in the restoration of class V caries in high-risk caries patients.
