Conservative procedures using dentin-bonding agents are one of the important aspects of pediatric dental practice. The objectives of this in vitro study was to comparatively evaluate the tensile-bond strength, fracture mode (under SEM) and microleakage of total etching single bottle system to self-etching adhesive system in primary dentition. The flat buccal/lingual surfaces of 20 teeth were divided into two groups and treated with Single Bond (Group 1) and Adper Prompt (Group 2) to develop a composite resin cone. Then tensile-bond strength was measured using Instron machine. Fracture mode was evaluated in three specimens from each group under SEM. Microleakage of Class V composite restorations (in 20 teeth) with the above-mentioned adhesives was assessed under stereomicroscope after Basic fuschin dye immersion. Results showed no statistically significant difference between two groups. It was concluded that concerning the single step application with similar efficacy, the self-etching adhesive is better for bonding in primary dentition.
