Article Synopsis
- This study investigates the effectiveness of hydroxyapatite-silver (HA-Ag) hybrid nanoparticles as an antibacterial agent in self-etch adhesives for dental applications, particularly in treating primary molar teeth with carious lesions.* -
- A total of 80 primary molars were divided into four groups based on the concentration of HA-Ag nanoparticles used—0%, 1%, 5%, and 10%—and their effects on microtensile bond strength (μTBS), antibacterial efficacy, and degree of conversion (DC) were assessed.* -
- Results showed that 1% HA-Ag nanoparticles provided the best balance of antibacterial properties, bond strength, and degree of conversion, while the 10% concentration
Objective: To evaluate the penetration and adaptation of highly viscous zinc-reinforced glass ionomer cement (ZRGIC), using a scanning electron microscope (SEM), when applied under various contaminated conditions on grooves and fissures of primary second molars. Materials and Methods: A total of 40 extracted human primary second molars were randomly assigned into five groups (8 teeth each), with different surface conditions (conditioned with 40% polyacrylic acid, dry condition, water contamination, saliva contamination, or saliva contamination and air-drying) on the occlusal surface before placement of zinc-reinforced highly viscous glass ionomer cement with the finger-press technique. After sectioning the teeth, they were subjected to SEM analysis, where four in each group underwent aging by thermocycling and the other four were without aging.
