| Summary: | ABSTRACT Objectives This study aimed to assess the impact of casein phosphopeptide‐amorphous calcium phosphate (CPP‐ACP) and proanthocyanidin (PA) on the microshear bond strength (μSBS) of universal adhesives to caries‐affected dentin (CAD) in primary teeth. Materials and Methods 160 human primary second molars with occlusal caries were utilized, with CAD‐exposed dentin surfaces. The teeth were categorized into four groups based on CAD pretreatment: no pretreatment, CPP‐ACP for 3 min, PA for 1 min, and PA for 1 min followed by CPP‐ACP for 3 min. Each group subdivided into four based on adhesive system (Gluma Bond Universal or All‐Bond Universal) and application mode (etch and rinse; E&R or self‐etch; SE). Following composite resin restoration, μSBS measurements were taken after 24 h of water storage. Results PA pretreatment showed the highest μSBS compared to controls and other methods (p < 0.001). Conversely, CAD pretreatment with CPP‐ACP + PA led to lower μSBS than the control (p = 0.009). Universal adhesive choice significantly influenced μSBS (p < 0.001), with Gluma Bond Universal outperforming All‐Bond Universal (p < 0.001). The E&R method demonstrated superior bond strength over SE (p < 0.001). Conclusion CAD pretreatment, particularly with PA, significantly impacted bond strength, with Gluma Bond Universal and the E&R method proving optimal for enhancing μSBS to CAD. These findings offer valuable insights for refining adhesive protocols in pediatric dentistry, potentially improving clinical outcomes in restorative procedures. |
