In Vitro Comparative Evaluation of Change in Mass, pH and Fluoride Release of Cention-N and Glass–Ionomer Cement

Objective: Type IX GIC is a preferred permanent restorative material in primary teeth for its tooth-colored restorative material, chemical bonding to tooth structure, better physical properties and fluoride release.This comparative study was done to evaluate physical properties of Cention-N with type IX GIC as manufacturer's claims better properties over GIC.Materials and methods: About 100 samples of 10 mm diameter and 3 mm thickness were made from Type IX GIC and CN using Teflon molds and stored in artificial saliva at pH (5.5) and stored individually in sterile plastic container at a constant temperature during the entire experiment.They were divided into two equal groups (group A and B).Samples from group A were used to determine the change in mass and pH and group B were used to determine fluoride release at different time intervals of 1 week and 1 month and was evaluated using electronic weighing machine, digital pH meter, and spectrophotometer.Results: Statistically significant pH and fluoride release were observed in CN both at the end of 1 week and 1 month, and a significant change in mass was observed in Type IX GIC at the end of 1 month.Conclusion: Cention-N can be a better alternative as it demonstrated an increase in pH and fluoride release than Type IX GIC.
