Background: The first dental experience is vital in molding a child's attitude towards dentistry and dental outcomes. The cooperation of a child during dental treatment is essential to render successful and high-quality treatment. Dental anxiety is common in children undergoing dental treatment. The success of pediatric dental treatments and patient comfort depends on controlling the levels of patient anxiety in clinical settings. This study aimed to compare the effectiveness of the recorded maternal voice and virtual cognitive tool (Roogies application) in the management of pediatric dental patients. Methods: The study was carried out with children aged of 4-7 years [n = 80, (40 male and 40 female)], without any past dental history, and were randomly allocated into two groups. After informed consent was obtained, the entire procedure was explained to the parents. Anxiety was assessed pre-, during, and post-treatment by measuring pulse rate, and recording Venham Picture Test (VPT) scores. Group A [n = 40; 20 boys and 20 girls)] was provided with a headphone that played a recorded maternal voice. Group B [n = 40; 20 boys and 20 girls)] was administered the virtual cognitive tool. After conditioning the children, oral prophylaxis was performed for both groups. A comparative evaluation was conducted for each treatment session. Results: The intra-group comparison of VPT scores and heart rate for patients assigned to the recorded maternal voice showed a statistically significant difference in dental anxiety (P-value ≤ 0.001). Conclusion: This study demonstrated that a reduction in dental anxiety with the help of recorded maternal voice forms an important component of non-pharmacological behavior management. Alternatively, the use of a virtual cognitive tool as an anxiety-reducing technique can also be advocated.

Strength and Durability Evaluation of Multi-Binder Geopolymer Concrete in Ambient Condition
Jay Bhavsar,Vijay R. Panchal 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.4
In recent decades, researchers have been fascinated with geopolymer concrete because of its minimal carbon footprint. Geopolymer concrete (GPC) has been found a viable alternative for recycling industrial waste. The efficient use of these wastes in geopolymer concrete reduces environmental pollution. In the study, three industrial wastes were utilized for making geopolymer concrete at ambient temperature. These wastes are fly ash, ground granulated blast furnace slag (GGBS), and two different ceramic polishing waste (CPW). The study proposes fly ash as the primary binder. GGBS is projected as the additive for ambient curing, and CPWs as a recycling binder. The alkali activators Na2SiO3 and NaOH were used to manufacture the concrete mixture consisting of three binders. Important GPC factors such as workability, mechanical strength, sorptivity, water absorption, acid resistance, and chloride resistance have been examined. Further Carbon footprint is also measured to know the environmental impact. The findings revealed an improvement in capillary porosity and chloride permeability with the increase of CPWs upto 20%. The SEM images revealed improvement in microstructure with an increase in CPWs upto 20%. The use of CPWs also reduced the Carbon footprint of GPC. The study determined that the mechanical, durability and environmental qualities of multi-binder GPC make it suitable for structural concrete.
