Abstract
Aim: Compare clinical performance and success/retention rates of two multi-mode (MM) adhesives, applied in self-etch (SE) or etch-and-rinse (ER) modes, with SE-all-in-one adhesive (SE/SE with enamel etching) in NCCL restorations at one-year follow-up.Material and methods: Prospective, double-blind RCT approved by the University Fernando Pessoa and the National-Clinical-Research-Ethics Committees (CEIC-20150305), ClinicalTrials.gov registered (NCT02698371), in 38 participants with 210 restorations (AdmiraFusion®) randomly allocated to six groups (Adhesives_Adhesion mode), each with 35 restorations: G1-Control Futurabond®DC_SE; G2-Control Futurabond®DC_SE with enamel etching; G3-Futurabond®U_ER; G4-Futurabond®U_SE; G5-Adhese®Universal_ER; G6-Adhese®Universal_SE. Restorations evaluated at baseline and one-year by three calibrated examiners (ICC ≥0.952) using FDI criteria and statistical analysis with nonparametric tests (alpha = 0.05).Results: At one-year recall 36 participants, 199 restorations were available for examination; five (2.5%) restorations (G1 n = 2; G2, G3, G4 n = 1) were lost due to retention (p > .05); G1 showed less satisfying marginal adaptation (p < .05) than G2 and MM adhesives groups, particularly G6. Overall success rates (p > .05) were: 93.9% (G1), 97.0% (G2; G3; G4) and 100.0% (G5; G6).Conclusions: MM adhesives (Futurabond®U and Adhese®Universal) showed similar and acceptable performance/success rates but also better clinical outputs than the SE-all-in-one adhesive (Futurabond®DC), particularly in SE mode. Success and retention rates were similar and not dependent on materials or adhesion modes.
Highlights
Multi-mode adhesives (MM) are contemporary simplified dental adhesives which can be used either in etch-and-rinse (ER) or self-etch (SE) adhesion approaches
The results showed that only three restorations had failed due to loss of retention within the group where the mild SE adhesive was applied after phosphoric acid pre-treatment of the dentine [27]
Thirty-eight patients received a total of 210 Non-carious cervical lesions (NCCLs) restorations distributed across two control (G1, G2) and four (G3 to G6) study groups
Summary
Multi-mode adhesives (MM) are contemporary simplified dental adhesives which can be used either in etch-and-rinse (ER) or self-etch (SE) adhesion approaches These universal systems allow for the application of the adhesive with phosphoric acid preetching, in the total-etch or ER modes, or using selective etching approaches, which enhance enamel bond durability and provide a simplified SE mode procedure on dentine [1]. The impregnation of the dentine substrate by resin monomers and the stability of the bonded interface are of paramount importance to clinical performance [23] These lesions are considered advantageous when assessing adhesive systems
