Abstract

Introduction: Carboxymethyl chitosan/amorphous calcium phosphate (CMC/ACP) is a non-collagenous protein analog material with dentin remineralization ability, and gypsum is a mixing material that facilitates the clinical application. Gypsum is a natural material used to release the regenerative calcium ion and has a good biological response, with osteoconductive, resorbable, and compatible properties. Objectives: The aim of this study was to examine the effect of the addition of gypsum to the non-protein analog material CMC/ACP in dentin remineralization. Material and methods: Tooth samples for this study were taken from patients with tooth impactions at the Maxillofacial Surgery Clinic. Twenty-seven cavities were divided into three groups: Dentin demineralization withAoût any material applied, application of dentin demineralization with CMC/ACP, and application of dentin deminerAâlization with gypsum + CMC/ACP. The results were elucidated on Day 14, using scanning electron microscopy with energy-dispersive X-ray. The data were analyzed using Statistical Package for the Social Sciences version 22 software (IBM Corp., Armonk, NY, USA), analysis of variance (ANOVA) one-way statistic test, and Kruskal-Wallis test. Results: Gypsum showed a positive effect on the ability of CMC/ACP in dentin remineralization. The edge of the dentin tubules appeared to be irregular and smaller, with some covered up. This shows remineralization occurrence after the bio-active material of the CMC/ACP and gypsum application. Conclusions: The addition of gypsum to the CMC/ACP has a positive effect in dentin remineralization.
