Abstract
Objective: Caries cause progressive demyelination in the tooth structure. Considering the importance of milk teeth in the growth and nutrition of children and the concerns of parents about the decay of milk teeth, this study was conducted with the aim of calcium-containing compounds to reduce the decay of milk teeth.
Methods: In the current laboratory study 36 human primary mandibular incisors were included. The samples were subjected to a hardness test (50 gr, 10 hours) after proper cleansing (primary measurement). Then the samples were randomly divided into 3 groups as follows (N=12): the GC tooth mousse group, the fluoride varnish group, and the control group. The teeth were exposed to the test materials based on their group and their hardness was measured (secondary measurement). Finally, each group was placed in acetic acid for 6 hours the hardness was measured for the third time (tertiary measurement). Data were analyzed using SPSS V.22.
Results: The findings showed that the enamel resistance after exposure to fluoride and GC was 471.86 and 405.45, respectively. On the other hand, after exposure to acid, resistance was reduced to 291.5 and 233.66 in the fluoride and GC groups, respectively. The highest resistance was observed in the fluoride, GC, and control groups, respectively. The enamel resistance in the fluoride and GC groups were 82.2 and 38.99 units higher than in the control group, respectively. This difference was statistically significant (P=0.001).
Conclusion: The results of the present study showed that both fluoride varnish and GC tooth mousse increased the enamel resistance. However, fluoride varnish had better outcomes compared to GC tooth mousse.
