Six-year clinical evaluation of a copper-containing universal adhesive in non-carious cervical lesions: A split-mouth double-blind randomized clinical trial.

Objectives: To evaluate the clinical performance of a universal adhesive system containing 0.1 % copper nanoparticles (CuNp) in non-carious cervical lesions (NCCLs) after 6 years.

Material And Methods: Two hundred and sixteen restorations (n = 54) were randomly placed in 36 participants with at least four NCCLs.

Clinical performance of an ormocer-based single-shade resin composite for the restoration of non-carious cervical lesions: 18-month randomized clinical trial.

Objective: This double-blind, split-mouth, randomized equivalence clinical trial aimed to evaluate the 18-month clinical performance of an ormocer-based single-shade resin composite compared with an ormocer-based multi-shade resin composite in non-carious cervical lesions (NCCLs).

Methods: One hundred and twenty restorations were performed on NCCLs with two restorative materials (n = 60): Admira Fusion X-tra resin composite (ormocer-based single-shade), and Admira Fusion resin composite (ormocer-based multi-shade). After rubber dam isolation, a universal adhesive was applied in the selective enamel etching strategy.

Prediction based on machine learning of tooth sensitivity for in-office dental bleaching.

Objective: To develop a supervised machine learning model to predict the occurrence and intensity of tooth sensitivity (TS) in patients undergoing in-office dental bleaching testing various algorithm models.

Materials And Methods: Retrospective data from 458 patients were analyzed, including variables such as the occurrence and intensity of TS, basal tooth color, bleaching material characteristics (concentration and pH), intervention details (number and duration of applications), and patient age. Classification and regression models were evaluated using 5-fold cross-validation and assessed based on various performance parameters.

Color evaluation of a one-shade used for restoration of non-carious cervical lesions: an equivalence randomized clinical trial.

Background: Obtaining a perfect color match with resin composite presents a significant challenge. The chameleon effect has enabled resin composite to mimic the color of the adjacent tooth structure in vitro. This double-blind, split-mouth and equivalent randomized clinical trial evaluated the color matching of one-shade resin composite with chameleon effect versus multi-shade resin composite in non-carious cervical lesion restorations (NCCLs).

Re-evaluating the role of moist dentin of adhesive systems used in the etch-and-rinse bonding strategy. A systematic review and meta-analysis.

Background: The wet-bonding protocol has been used in the etch-and-rinse (ER) mode to maintain adhesive infiltration in demineralized dentin. This study answered the research question: "Do the retention rates and other secondary outcomes of composite restorations in non-carious cervical lesions (NCCLs) differ between dry- and wet-bonding techniques?"

Methods: The authors included randomized clinical trials in which NCCLs were restored with ER or universal adhesives applied under dry and moist dentin. Searches for eligible articles were performed in MEDLINE via PubMed, Web of Science, Cochrane Library, Brazilian Library in Dentistry, Latin American and Caribbean Health Sciences Literature, Scopus, Embase, and grey literature without language and date restrictions and updated in May 2024.
