Objectives: Glass ionomer cements (GICs), which are biocompatible and adhesive to the tooth surface, are widely used nowadays for tooth restoration. They inhibit the demineralization and promote the remineralization of the tooth structure adjacent to the restoration, as well as interfere with bacterial growth. Hence, the present study was conducted to assess and compare the antimicrobial activity of three commercially available GICs against two cariogenic bacteria.
Materials And Methods: An agar plate diffusion test was used for evaluating the antimicrobial effect of three different GICs (Fuji IX, Ketac Molar, and d-tech) on () and (). Thirty plates were prepared and divided into two groups. The first group was inoculated with , and the second group was inoculated with . These plates were then incubated at 37℃ for 24 hours. Zones of bacterial growth inhibition that formed around each well were recorded in millimeters (mm).
Results: The zones of inhibition for Fuji IX, Ketac Molar, and d-tech on were found to be 10.84 ± 0.22 mm, 10.23 ± 0.15 mm, and 15.65 ± 0.31 mm, respectively, whereas those for were found to be 10.43 ± 0.12 mm, 10.16 ± 0.11 mm, and 15.57 ± 0.13 mm, respectively.
Conclusions: D-tech cement performed better in terms of the zone of bacterial inhibition against the two test bacteria, than the other two tested glass ionomers.

Objective This in vitro study evaluated the impact of different time intervals on the color stability of glass ionomer cement (GIC) and composite materials bonded to teeth treated with silver diamine fluoride (SDF). Specifically, the study sought to determine if immediate or delayed application of these restorative materials affects the degree of staining caused by SDF. Materials and methods Twenty-eight extracted primary molars with cavitated lesions were randomly divided into four groups, each comprising seven samples.

The World Health Organization (WHO) has added glass ionomer cement (GIC) to the WHO Model List of Essential Medicines since 2021, which represents the most efficacious, safe and cost-effective medicines for priority conditions. With the potential increase in the use of GIC, this review aims to provide an overview of the clinical application of GIC with updated evidence in restorative and preventive dentistry. GIC is a versatile dental material that has a wide range of clinical applications, particularly in restorative and preventive dentistry.

Objective: This study aimed to evaluate the in vitro effects of coffee exposure on the color and roughness of conventional and bulk-fill resin composites, with and without surface pre-reacted glass-ionomer (S-PRG) filler.
Methodology: Forty-eight cylindrical samples (Ø6 mm × 2 mm) were prepared and categorized as follows (n = 12 per group): conventional nano-hybrid (Tetric N-Ceram, Ivoclar); nano-hybrid with S-PRG filler (Beautifil II, Shofu); bulk-fill (Tetric N-Ceram Bulk Fill, Ivoclar); and bulk-fill with S-PRG filler (Beautifil Bulk Restorative, Shofu). The samples were assessed for surface roughness (Ra, μm), color coordinates (CIE Lb), and overall color change (ΔE, ΔE).

Background And Aim: This study aims to evaluate the efficacy of different endodontic irrigants employed in the lesion sterilization and tissue repair (LSTR) technique.
Methods: Forty children aged 4-8 years having at least one primary molar with irreversible pulpitis/pulpal necrosis indicated for pulpectomy were included. Participants were randomly divided into three test groups (Group A, B, and C) and one control group (Group D).

Objectives: Comparative evaluation of indirect pulp therapy (IPT) with silver diamine fluoride (SDF), Type VII glass ionomer cement (GIC), and calcium hydroxide (Ca(OH)2) in young permanent molars.
Materials And Methods: This was randomized controlled trial, in which 45 children with 60 young permanent first molars were allocated as; Group A: IPT with SDF, Group B: Type VII GIC, and Group C: Ca(OH)2. Clinical and radiographic evaluation and comparison was done at baseline, 3, 6, 12 months.
