The anti-caries effects of dental adhesive resin influenced by the position of functional groups in quaternary ammonium monomers

Adhesive systems and resin composites are widely used in direct dental restoration due to esthetics and improved properties [1 –3]. However, the failure of composite restorations is still a major problem. The failure rate ranges from 15% to 50% according to previous survival investigation [4–6]. Replacement dentistry accounts for more than 50% of all the restorations performed, and costs more than $5 billion annually in the U.S [7–9]. The main reasons for the failure are secondary caries and bulk fraction [10–13].
