Abstract

Objectives: This study aimed to compare the microtensile bond strength (µSBS) of 5th-generation bonding agents to universal (one-bottle) bonding agents on dentin of posterior teeth.

Methods: Three different 5th-generation and three universal bonding agents from Charisma (Kulzer GmbH, Germany), 3M (3M ESPE, United States), and Tokuyama (Tokuyama Corporation, Japan) were tested using the microtensile bond strength (μ-SBS). Each adhesive system was applied to dentin surfaces bonded to composite resin, with ten samples per group (n=10). All six groups underwent μ-SBS testing.

Results: The generation of bonding agent significantly influenced µSBS (pth generation dental adhesives exhibited higher microtensile bond strength than universal dental adhesives.

Conclusion: This study confirms that 5th-generation bonding agents provide superior microtensile bond strength compared to universal adhesives when bonding composite resin to dentin. These findings highlight the importance of adhesive selection in achieving durable restorations.
