The most frequently used and universally accepted technique for removing caries is mechanical ablation of decayed tissues by rotating drills. New minimally invasive strategies, such as the use of lasers to perform highly controlled tissue ablation, have been introduced in dental practice. The aim of this study was to assess and compare treatment with a 2940 nm erbium/yttrium–aluminum–garnet (Er:YAG) laser versus a conventional rotary treatment during cavity preparation in children with regard to restoration integrity. In a randomized, controlled, blinded trial using a split-mouth design, 40 (9–12-year-old) children with 80 carious primary molars were included. The cavity in one quadrant was randomized to be treated conventionally using a bur, while the cavity in the other quadrant was prepared using an Er:YAG laser. At the one-year follow-up, clinical examinations were conducted to assess the integrity of the restorations according to the Ryge criteria. The data were analyzed using SPSS version 22 (IBM Inc., Chicago, IL, USA). The average age of the participants was 9.4 ± 1.29 years. Males accounted for 51.4% of the participants. The Ryge criteria showed clinical success of restorations, and there was no discernible difference between the conventional and laser intervention techniques. Over one year, no statistically significant differences in the clinical integrity based on the Ryge criteria were found following class I cavity preparation in primary teeth with either procedure.

“…To prevent the resin polymerization from overheating after initial polymerization, the samples were submerged in distal water. 14 Standardized class V cavity preparation were created on the buccal surfaces. (2mm height, 3mm width, 2mm depth) with the cervical margin 1mm above the cemento enamel junction (the occlusal and cervical margins of the preparations were completely in enamel).…”

“…Round bur was used for finishing the cavity form with a low speed hand piece. 14 According to the type of restoration to be tested, the teeth were divided randomly into five experimental groups each with five teeth: Alkasite without adhesive (Group 1): The created cavities were gently dried using air stream. One scoop of powder and one drop of liquid of alkasite were dispensed on a mixing pad, the powder was progressively added to the liquid and properly mixed for 60 seconds in accordance with the manufacturer's instructions.…”

Aims: To compare and evaluate marginal and internal adaptation and to assess the degree of conversion of alkasite restoration in relation with other restorative materials. Methods: on the buccal surface of 25 maxillary premolars a class V cavities were prepared. The teeth were randomly divided into five groups (n=5) that restored as: Group 1: alkasite without adhesive, Group 2: alkasite with adhesive, Group 3: Nanohybrid composite, Group 4: Glass ionomer cement, and Group 5: Resin modified glass ionomer cement. The teeth underwent 5000 cycles of thermocycling between 5° and 55°. Then, silver nitrate solution was infiltrated and Micro-Computed tomography analysis was performed using (LOTUS inVivo). For evaluating degree of conversion, 15 specimens in the form of a disc were prepared from Alkasite, nanohybrid composite and resin modified glass ionomer (n=5). All samples were analyzed using (FTIR) in an ATR Mode in three intervals (after 20 second. 24 hours and 7 days). The data had been analyzed using the Kruskal-Wallis, Dune and Wilcoxon tests at a 0.05 significance level. Result: A significant difference in marginal and internal adaptation were observed among restorations (p < 0.05). Superior marginal and internal adaptation was obtained in this study for alkasite whether with or without bonded over nanohybrid composite. However, RMGIC and GIC show more adaptation values among other tested groups. Also degree of monomer conversion percentage varied among restorations at different intervals. Conclusion: alkasite restorations wither with or without bonding have higher marginal and internal adaptation in comparison with nanohybrid composite but lower than that of GIC and RMGIC. Also alkasite restoration showed higher degree of conversion when compared with nanohybride composite and RMGIC after 20 second and 24 hours of polymerization

Aim:The aim of this in vitro study was to assess and compare the effect of the nano-coating on microleakage of different capsulated conventional glass ionomer cement (CGIC), resin-modified glass ionomer cement (RMGIC) and hybrid glass ionomer cement in primary molars. Materials and Methods:A total of 36 primary molars samples were divided into three groups. Group 1 -teeth restored with capsulated RMGIC (Fuji II LC) without nano-coating. Group 2 -teeth restored with capsulated CGIC (Fuji IX) with nano-coating. Group 3 -teeth restored with capsulated hybrid glass ionomer (Equia Forte) with nano-coating. Microleakage was tested using immersed the teeth in 2% methylene blue dye penetration for 24 hours after the thermocycler and measured at x40 magnification under the stereomicroscope. Results:The results of this in vitro study showed that coating with nano-coating showed a reduction in microleakage in hybrid glass ionomer (Equia Forte) and more microleakage in non-coating RMGIC (Fuji II LC) but also more microleakage in coating CGIC (Fuji IX), which was statistically significant. CGIC with nano-coating and RMGIC without coating showed highest microleakage followed by hybrid glass ionomer (Equia Forte) with coating. Conclusion:Significant reduction in microleakage was seen in Equia Forte (hybrid glass ionomer) with nano-coating and the coating should use with all types glass ionomer.
