Comparison of the abrasive effects of children's toothpaste on glass ionomer cement

Objectives

To evaluate the effect of two different children's toothpaste on the surface properties of conventional glass ionomer cement (GIC), which is used in Atraumatic Restorative Treatment (ART) method.

Methods

There were 3 groups and 10 glass ionomer cements in each group. The distribution was as follows: Group 1, Splat; Group 2, R.O.C.S.; Group 3, Control. A test aparatus made of steel with a screw design that allows the replacement of electric toothbrushes was designed to provide 2 N force. Brushing was carried out for each samples for duration of 2 min, twice a day, for seven days. One-way ANOVA for intergroup comparison and paired sample T tests for intragroup comparisons were used in statistical analysis, the significance level was p < 0.05.

Results

According to the results, no statistically significant difference was found between the baseline and 7th day roughness values within and between groups (p > 0.05). Although not statistically significant, as a percental increase in roughness was found in each group compared to the initial values. This amount of increase was found in Group 2, Group 1 and Group 3 as a descending order. The results were supported by scanning electron microscopy analysis.

Conclusion

As a result of this study, child pastes that do not cause a statistically significant increase in roughness were found to be safe for daily use. When considering long-lasting restorations, low relative dentin abrasivity (RDA) value child pastes can be recommended as they will encourage brushing with both taste and smell compared to brushing with water.
