Influence of different finishing, aging with coffee, and repolishing protocols on the properties of nanoparticle composite resins.

Background: Considering the variability of finishing protocols for composite resins, the literature does not offer a consensus about the influence of these approaches to obtain a final polishing and whether the physical properties of these composite resins change at different analysis times. Therefore, the study analyzed the microhardness, roughness, color stability, and gloss of a nanocomposite resin with different finishing, aging with coffee, and repolishing protocols.

Material And Methods: Nanocomposite resin samples were divided into three finishing protocol groups: Diamond burs (F and FF), multi-fluted tungsten carbide burs (18 and 30 flutes), and coarse and medium abrasive discs (Soflex-3M).

Knowledge and practice of dentists in processing polishing points: A cross-sectional study.

Background: Adequately processing polishing points used to polish composite resin restorations is necessary for microbiological control in dentistry, but there is no specific protocol to guide professionals. Therefore, this study aimed to assess the knowledge and practice of dentists in processing these instruments.

Methods: This cross-sectional observational study included the application of an online questionnaire via Google Forms and social media promotion.
