Esthetic compomer restorations in posterior teeth using a new all-in-one adhesive: case presentation.

UNLABELLED: Compomers have continually gained in importance since their introduction in 1993, especially because of their ease of handling. The main indications are cervical lesions, Class III restorations, and restorations in the primary dentition. To extend the indications of compomers to esthetic Class I and II restorations in the permanent dentition, improvements in wear resistance and bond strength need to be accomplished. Studies have shown an improved bond strength and less marginal gap formation between compomers and enamel and dentin with acid etching of the tooth before application of conventional mild self-etching adhesives. Newly formulated, improved self-etching adhesives with a higher demineralization potential recently have been developed. The objective of this case presentation is to demonstrate step-by-step the clinical procedure for the application of a newly developed self-etching adhesive with high demineralization potential in combination with a compomer material in occlusal cavities. CLINICAL SIGNIFICANCE: Improved self-etching adhesives provide a faster and simplified application technique and allow effective conditioning and priming of enamel and dentin in one step, without waiving sufficient bond strengths. With limited indications, compomers are used in combination with these self-etching primers to restore occlusal cavities in posterior teeth. Evidence-based dentistry requires exact scientific data to evaluate whether this new trend results in benefits for patients. However, until clear evidence from controlled clinical studies supports the use of improved compomer systems in Class I and II cavities in the permanent dentition, dentists should be careful with this indication.
