RESUMO
Aim: The study aimed to compare and assess the dissolution rate, color stability, and other mechanical parameters, such as compressive and flexural strength, of three distinct posterior restorative materials used in pediatric dentistry. Materials and methods: The three posterior restorative materials used in pediatric dentistry are divided into group I-Zirconomer, group II-Composite, and group III-Cention N. Around 111 cylindrical specimens were grouped into three groups of 37 each. According to the manufacturer's standards, all materials were proportioned and handled. The materials were thermocycler in a chewing simulator and were subjected to various tests to estimate the dissolution rate, compressive strength, flexural strength, and color stability of the three individual groups. Results: The dissolution rate was highest in Zirconomer, followed by Cention N and Composite, which were highly significant (p = 0.05). Compressive strength was highest with Cention N, followed by Composite and Zirconomer, which was highly important (p = 0.05). Cention N had the greatest flexural strength, followed by Composite and Zirconomer, which were highly significant (p = 0.05). Finally, the Composite had the highest color stability, followed by Cention N and Zirconomer among the three groups. Conclusion: It is concluded that resin-based restorative materials outperform glass ionomer-based Zirconomer cement in terms of dissolution rate, compressive strength, flexural strength, and color stability. Clinical significance: Because of the widespread improvement in dental materials, many dental restorative types of cement have emerged on the market. The features of good restorative materials are mechanical strength, fluid dissolution rate, and retention. How to cite this article: Raman V, Srinivasan D, AR SE, et al.

RESUMO
Aim: Prevention-focused school dental health program (SDHP) is a cost-effective intervention that countries can use to lessen the problem of dental diseases by educating on oral health. The current study aims to assess the effectiveness of parental participation in an SDHP held at periodic intervals on the oral health status (OHS) of children aged 8-10 years attending a local school in Southern India. Materials and methods: The longitudinal study was scheduled between September 2018 and June 2019 (36 weeks) in 120 participants who were healthy school children aged 8-10 years at a private school in Kelambakkam. This 36-week duration study assessed the effectiveness of school dental health education program with and without parents at every 12 weeks interval. The OHS of subjects was assessed using the standard indices [i.e., Decayed, Missing and Filled permanent teeth (DMFT), decayed, extracted, and filled primary teeth (deft), and Simplified Oral Hygiene Index (OHI-S)]. Friedman's test and Mann-Whitney U test were used for analyzing the data as indicated. Results: In postintervention visits, children with parental participation had significantly lower caries increments than children without parental participation. While the oral hygiene index scores have improved significantly in both groups over time, the improvement in the parental participation group was greater. Conclusion: It can be concluded that the SDHP is an educational driver that showed a constructive impression on the oral health of children. The participation of the child's parents in SDHP has significantly improved the OHS of children. How to cite this article: Sowmiya Sree RA, Joe Louis C, Senthil Eagappan AR, et al.
