Comparison of Class II Bulk-Fill, Self-Adhesive Composites, Alkasite, and High-Viscosity Glass Ionomer Restorations in Terms of Marginal and Internal Adaptation.

(1) Background: Restoring decayed teeth in young patients can be challenging. This calls for a simplification of the protocols through new biomaterials. Therefore, the aim of this study was to compare the marginal adaptation delivered by restorative materials applied on class II cavities by using a simplified protocol, before and after fatigue test, followed by the assessment of the internal adaptation.

Efficacy of P-4 for the treatment of initial buccal caries: a randomized clinical trial.

To investigate the safety and efficacy of Self-Assembling Peptide P-4 (SAP P-4) compared to placebo or fluoride varnish (FV), a randomized, controlled, blinded, split-mouth study with sequential design was conducted. Subjects presenting two teeth with White-Spot-Lesions (WSLs) were included and teeth were randomly assigned to test or control. Control received placebo at baseline (D0) and test SAP P-4, all received FV at Day 90 (D90).

Evaluation of marginal adaptation, seal and resistance against fatigue cracks of different pit and fissure sealants under laboratory load.

Purpose: To evaluate, in the laboratory, five light-cured pit and fissure sealants (ClinPro Sealant, Grandio Seal, Delton Seal-N-Go Illuminating, Embrace WetBond, Delton LC) and a filled bonding resin (Optibond FL Adhesive) used as a sealant in respect to their marginal adaptation before and after simultaneous thermal cycling and occlusal loading and their seal and failure cracks after loading.

Methods: 60 caries-free upper molars were mechanically and thermally loaded after sealant application. Marginal adaptation was evaluated in the SEM before and after loading and a dye penetration test was performed after loading.
