A Comparative Evaluation of Dissolution Rate of Three Different Posterior Restorative Materials used in Pediatric Dentistry: An Study.

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 ( = 0.05). Compressive strength was highest with Cention N, followed by Composite and Zirconomer, which was highly important ( = 0.05). Cention N had the greatest flexural strength, followed by Composite and Zirconomer, which were highly significant ( = 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.
