This concise review provides an update of the use of dental sealants. Dental sealants protect a tooth from caries development by providing a physical barrier to microorganism colonisation and creating a favorable environment for patients to clean. Some sealants release fluoride ions to promote remineralization. Dental sealants can be applied on pits and fissures of primary and permanent teeth to prevent and arrest early enamel caries. They are effective in caries prevention. The preventive fraction of resin sealant is up to 61% after 5 years...

The objective of this study was to evaluate the aging effects of long-term exposure to acidic beverages on the flexural strength (FS) and chemical reactions of two resin-based composites (RBCs) and one giomer. The FS of composite specimen bars (2 mm × 2 mm × 25 mm) was measured using a universal testing machine at various levels of thermocycling (TC; 0, 10,000, 50,000, and 100,000 cycles) in two beverages with different pH values (distilled water [DW], pH 7.0; Coca-Cola, pH 2.4-2.8). The FS data were analyzed using three-way analysis of variance with the post hoc Tukey test and t-test at a significance level of a=0...

INTRODUCTION: There are several cosmetic, restorative materials to restore non-carious Cervical Lesions (NCCLs). The aim of this study was to specify and compare the shear bond strength of Giomer and resin-modified glass ionomer in Class V lesions so that whether Giomer showed a better shear bond strength, it could be used instead of RMGI to restore NCCLs because of its better esthetic. METHOD: ology: 20 maxillary and 20 mandibular intact premolars were collected...

The study aimed to investigate the rechargeability of ion-releasing dental material specimens immersed in distilled water for 25 months, which depleted their ion-releasing ability. Four restorative dental materials (alkasite composite, giomer, glass-ionomer, and composite material) presented with 24 specimens were studied after topical treatment with a concentrated fluoride gel. The effect of resin coating on the ion uptake and release was investigated on additional 42 specimens of restorative dental materials with coatings...

Purpose: The purpose of this study was to evaluate the effect of 38 percent silver diamine fluoride (SDF) application on the shear bond strength (SBS) of three types of bulk-fill restorative materials to dentin. Methods: Eighty recently extracted deidentified, sound, human premolar teeth were sectioned to expose the mid-coronal dentin. A composite restorative material (ACTIVA™), a giomer (Beautifil® ), and a high-viscosity glass ionomer (HVGI) cement (Equia Forte® ) were used. The specimens were randomly assigned into eight groups (<small>N</small> equals 10 per group) according to the type of restorative material (ACTIVA™ , Beautifil ® , Equia Forte ® with and without the conditioner) and pretreatment with one drop of 38 percent SDF...

METHODS: One-hundred FPMs with MIH which were indicated for non-invasive fissure sealant were selected in 39 children, aged 6-12 years. Using a split mouth design, the FPMs were randomized into two groups; Group 1...

Flexural strength, flexural modulus, and Weibull modulus were measured one day, three months, and after three months with accelerated aging in ethanol...

This study investigated the potential of adhesive coating for hindering the reactivity of ion-releasing dental restorative materials. Experimental composites were prepared by replacing 10 or 20 wt% of reinforcing fillers with two types of bioactive glass. A glass ionomer, a giomer, and an alkasite were used as representatives of commercial ion-releasing materials. Restorative material specimens were coated with an etch-and-rinse adhesive, 1-step self-etch adhesive, 2-step self-etch adhesive, or left uncoated...
