Clinical Performance of ARS Containing Universal Adhesives in Carious Cervical Lesions

Clinical Performance of Universal Adhesive with and Without Acid Resistant Silane Coupling Agent in Carious Cervical Lesions :A Randomized Controlled Trial

Evaluation of composite restorations done in carious cervical lesions restored by a conventional universal adhesive in comparison to a universal adhesive that contains and resistant silane coupling agent according to the Modified United States Public Health Service (USPHS) criteria over 18 months.

The presence of acidic monomers in the bottle during storage can lead to the hydrolysis of silane contained in universal adhesives, potentially reducing its effectiveness and causing instability,The acid resistant silane coupling agent has a protective structure against attacks from acidic monomers. Therefore, long-term storage stability can be expected by suppressing hydrolysis. The protective structure is removed when the concentration of acidic monomers increases by air drying after application. This activates ARS, exerting the silane coupling effect.
