The aim of this study was to compare the shear bond strengths (SBS), failure modes (adhesive, cohesive, or mixed), and marginal microleakage occurrence of conventional resin (CR)-based, glass ionomer (GI)-based, and self-adhesive resin (SAR)-based fissure sealants with or without prior phosphoric acid (PA) etching. Fifty extracted premolars were randomly and equally assigned into five groups -G1:PA+CR, G2:PA+GI, G3:GI, G4:PA+SAR, and G5:SAR. Prior PA etching significantly (p<0.05) increased the SBSs of sealants. Adhesive failure mainly occurred in teeth treated with SAR- or GI-based fissure sealants, and cohesive failure mainly occurred in PA-etched teeth. Microleakage occurrence differed significantly (p<0.05) among the five groups of treated teeth. We concluded that conditioning of a tooth's enamel surface is crucial to creating strong bonds and leak-free sealing between tooth and fissure sealant.

Purpose: To make micro-CT comparison and evaluation of sealant penetration depth in different types of fissures after heating of the material or application of vibrations.
Materials And Methods: One hundred sound third molars have been sealed as follows: group 1 (n = 20), light-cured resin sealant at room temperature, group 2 (n = 20), light-cured resin sealant, preheated to 41.0°C, group 3 (n = 20), light-cured resin sealant, preheated to 51.

Background: Preventive dental procedures are cornerstones of caries management.
Introduction: This research aims to analyze the clinical effectiveness of pit and fissure sealants when applied to etched enamel pretreated with solvents compared to the conventional etch and seal technique.
Subjects And Methods: Children and adolescents with clinically healthy occlusal surfaces or noncavitated occlusal carious lesions on permanent first and/or second molars in all four quadrants were randomly allocated into four groups.

Background: This study aimed to develop ion-releasing and antibacterial resin-based dental sealants comprising 3 to 6 wt% monocalcium phosphate monohydrate (MCPM, M), 3 to 6 wt% bioactive glass (BAG, B), and 3 to 6 wt% polylysine (PLS, P). The physical properties, mechanical performance, cytotoxicity, and inhibition of S. mutans biofilm by these materials were subsequently evaluated.

Various interventions are available for the management, of which microinvasive techniques such as infiltration, sealants, glass ionomers, are novel and convenient. The purpose of this systematic review and meta-analysis was to compare microinvasive techniques with noninvasive or invasive treatment modalities in terms of effectiveness in halting interproximal caries lesion progression radiographically assessed.

Objectives: To identify and map the literature on the current state of pH-triggered strategies for resin-based materials used in direct restorative dentistry, focusing on innovative compounds, their incorporation and evaluation methods, and the main outcomes.
Data And Sources: Through a search across PubMed, Scopus, Embase, Web of Science, LILACS, Cochrane Library databases, and Google Scholar, this review identified studies pertinent to pH-responsive dental materials, excluding resin-modified glass ionomer cements.
Study Selection: From the 981 records identified, 19 in vitro studies were included, concentrating on resin-based composite resins (50 %), dentin adhesives (25 %), and sealants (25 %).
