The clinical evaluation of a single-bottle adhesive system with three restorative materials in children: six-month results.

This study was designed to evaluate the clinical performance of a single-bottle adhesive system with three restorative materials placed in children using the total-etch technique. One hundred thirty restorations were placed on conservative preparations in 36 children using the incremental placement technique in a clinical environment. The restorations were evaluated within a week of placement (baseline) and again after six months. The criteria evaluated included retention, color match, marginal discoloration, marginal integrity, surface roughness, postoperative sensitivity, recurrent caries, and wear. Indirect evaluations of anatomical form, marginal adaptation, and wear also were conducted. Clinical evaluation demonstrated no significant differences between the three restorative materials. Five restorations had to be replaced: two compomer, two packable composite, and one amalgam. There was no clinically detectable wear in any of the restorations.
