Comparison of Four Universal Adhesive Protocols for the Internal Adaptation of Composite Restorations in Primary Teeth: An In Vitro Micro-CT Study.

Researchers compared how well four combinations of universal adhesive products and application methods adapted to composite restorations in extracted primary molars using micro-CT imaging after thermocycling. One adhesive system showed lower interfacial gaps with self-etch compared to selective enamel etching, but other combinations showed no significant differences.
