Background

Systematic reviews have shown that three-step etch-and-rinse adhesive systems, two-step self-etch systems, and one-step self-etch adhesive systems provide similar clinical effectiveness for restorations of noncarious cervical lesions. The evidence has most often been gathered in permanent teeth and cannot be directly extrapolated to primary dentitions. Primary molars are the most common teeth restored in pediatric practice, with restorations placed on either the occlusal or occluso-proximal

Methods

The PubMed/MEDLINE, Cochrane, SciELO, Lilacs, and Scopus databases were searched for systematic reviews and meta-analyses covering the bond strength associated with the use of three-step etch-and-rinse, two-step self-etch, and one-step self-etch adhesive systems for primary tooth situations. Thirty-nine relevant articles were identified, with 36 considered in the meta-analysis (Fig 1). Bond strength data were collected and assessed.

Results

Higher bond strength was found with restorations in sound enamel and dentin than in demineralized enamel and caries-involved dentin. However, no statistically significant differences in bond strength were noted between the two adhesive systems in caries-affected dentin during immediate evaluation and sound dentin after aging. Both two-step etch-and-rinse and self-etch adhesives in dentin substrates tended to have higher bond strength values. The three-step etch-and-rinse adhesives had better

Discussion

No statistically significant difference in bond strength values was noted for etch-and-rinse and self-etch adhesive systems in carious dentin assessed immediately and sound dentin after aging. For primary teeth, etch-and-rinse adhesives have a better performance than self-etch systems.

Clinical Significance

Clinicians can feel confident that the current etch-and-rinse adhesive systems are the best choice for restoring primary teeth. Studies are needed to verify that these good results extend for
