THE EFFECT OF CARBOXYMETHYL CHITOSAN AMORPHOUS CALCIUM PHOSPHATE APPLICATION ON PRIMARY TEETH ENAMEL HARDNESS

Abstract

Dental caries is an oral disease that often occurs in children, especially in developing countries. The importance of early caries prevention triggers many studies on new prevention methods, especially remineralizing materials. Tooth remineralization can be observed by testing the hardness of the tooth structure. To analyze the effect of CMC-ACP application on the enamel hardness of primary teeth. Experimental laboratory study. 36 primary tooth enamel samples were used; the samples were demineralized with 37% phosphoric acid etching, then divided into 3 groups, namely the negative control group with no treatment, the positive control group with CPP-ACP application, and the CMC-ACP application group. The enamel hardness test was carried out after applying the material on 7 days and 14 days using Vickers Hardness Tester. The results of the enamel hardness test on day 7 and day 14 of CMC-ACP applications were calculated using the paired sample t-test with a significance limit of p<0.05. The results of this test p = 0.001. The results (p<0.05) showed that enamel hardness values on day 7 CMC-ACP application had a statistically significant difference from the group on day 14. There was a significant increase in primary tooth enamel hardness from the application of CMC-ACP on days 7 and 14.
