Secondary Caries

Brief summary

9 general practices in the Netherlands were provided with two composite resin adhesives, each for a period of 9 months. One contained MDPB (Adhesive P), and the other one was used as a control (Adhesive S). Patient's age, SES, and caries risk, as well as tooth type/number, reason for restoration placement, used restorative material and bonding agent, and affected surfaces were recorded. All interventions carried out on these teeth in the next 6 years were extracted from the electronic patient records, along with their date, type, reason, and surfaces. Two dependent variables were defined: general failure, and failure due to secondary caries. All data handling and statistical analyses were carried out in R 4.0.5.

Interventions

An adhesive is used routinely when placing resin composite restorations. This group receives a commercially available adhesive containing an antibacterial monomer (MDPB)
