Class V restorations, located at the cervical third of the tooth, present unique clinical challenges due to their proximity to the gingiva, presence of dentin and cementum substrates, and exposure to flexural forces. Bond strength between restorative materials and the tooth surface is critical for clinical success, affecting retention, marginal integrity, and resistance to microleakage. This paper explores how different adhesive strategies, substrate characteristics, and environmental conditions impact bond strength and, consequently, the longevity of Class V restorations. Evidence from in vitro and clinical studies is synthesized to provide a comprehensive understanding of the relationship between bond strength and restoration success.
