Universal Simplified Adhesive applied under different bonding technique's: 36-month Randomized Multicentre Clinical...

Area of Science:

• Restorative Dentistry
• Dental Materials Science
• Adhesive Dentistry

Background:

• Non-carious cervical lesions (NCCLs) represent a significant clinical challenge.
• Evaluating the long-term performance of universal adhesives is crucial for clinical decision-making.
• Futurabond U is a new dual-cure universal adhesive system.

Purpose of the Study:

• To assess the 36-month clinical performance of Futurabond U in NCCLs.
• To compare different application strategies: self-etch (SEE), selective enamel etching + self-etch (SET), etch-and-rinse with dry dentin (ERDry), and etch-and-rinse with wet dentin (ERWet).

Main Methods:

• Fifty subjects with NCCLs received restorations using Futurabond U and Admira Fusion composite resin.
• Four distinct bonding strategies were employed, with 50 restorations per group.
• Clinical evaluations were conducted at 36 months using FDI and modified USPHS criteria.

Main Results:

• Retention rates after 36 months were high: 87% (SEE), 94% (SET), 91% (ERDry), and 94% (ERWet).
• No significant differences in retention or marginal discoloration were observed between groups (p > 0.05).
• Minor marginal discrepancies were more frequent in self-etch groups, but no postoperative sensitivity or recurrent caries occurred.

Conclusions:

• Futurabond U demonstrated reliable clinical performance in NCCLs after 36 months, irrespective of the bonding strategy.
• While all strategies yielded satisfactory results, self-etch approaches showed a trend towards greater marginal discrepancies.
• The dual-cure universal adhesive is a dependable option for restoring NCCLs.
