Discrimination and dental students: What is the reality in Brazilian institutions?

Introduction: This study aimed to evaluate whether there is discrimination in the dental educational environment, assess the main reasons for the discriminatory events, and if there is an association between discriminatory episodes and sociodemographic characteristics of undergraduate dental students.

Materials And Methods: This observational cross-sectional study was conducted with a self-administered questionnaire to students enrolled in three Brazilian dental schools. Questions included sociodemographic characteristics and the occurrence of discriminatory episodes in the dental academic environment.

3D-printed microgels supplemented with dentin matrix molecules as a novel biomaterial for direct pulp capping.

Objectives: To develop a 3D-printed, microparticulate hydrogel supplemented with dentin matrix molecules (DMM) as a novel regenerative strategy for dental pulp capping.

Materials And Methods: Gelatin methacryloyl microgels (7% w/v) mixed with varying concentrations of DMM were printed using a digital light projection 3D printer and lyophilized for 2 days. The release profile of the DMM-loaded microgels was measured using a bicinchoninic acid assay.

Postoperative Sensitivity of Composite Replacement of Amalgam Restoration: A Randomized Clinical Trial.

Purpose: This randomized clinical trial aimed to evaluate the postoperative sensitivity of different resin composite/adhesive materials, placed either by an incremental or bulk-fill technique in posterior resin composite replacement of amalgam restorations.

Methods And Materials: A total of 47 patients with good overall health and at least four class I or class II amalgam restorations to be replaced participated in this study. The characteristics of 188 cavities were registered and randomly restored using incremental (Z350XT, 3M) or bulk-fill (Filtek Bulk Fill, 3M; Sonic Fill, Kerr; and Opus Bulk Fill, FGM) technique.

In-vitro models of biocompatibility testing for restorative dental materials: From 2D cultures to organs on-a-chip.

Dental caries is a biofilm-mediated, diet-modulated, multifactorial and dynamic disease that affects more than 90% of adults in Western countries. The current treatment for decayed tissue is based on using materials to replace the lost enamel or dentin. More than 500 million dental restorations are placed annually worldwide, and materials used for these purposes either directly or indirectly interact with dentin and pulp tissues.
