Efficacy of composites filled with nanoparticles in permanent molars: Six-month results.

This study sought to evaluate the clinical performance of composites filled with nanoparticles six months after placement in the occlusal surface of molars with Class I cavities. This study involved 41 patients, each of whom had three molars affected by primary caries or the need to replace restorations. All restorations were performed in accordance with the manufacturer's recommendations and evaluated in accordance with USPHS modified criteria. Based on the results of the present study, composites reinforced with nanoparticles can be used in posterior teeth, although their performance was not superior to that of the microhybrid composite. Long-term re-evaluations are necessary for a more detailed analysis of these composites.
