IN-VITRO EVULATION OF THE EFFECT OF KIDS TOOTHPASTES ON THE PRIMARY TEETH ENAMEL ROUGHNESS

Aim: the purpose of this study was to in-vitro evulation of the effect of kids toothpastes with different contents on the primary tooth enamel roughness. material and methods: this study was performed on 30 primary maxillary santral teeth buccal enamel surfaces, with newly exracted, non-carious and without surface defect. the teeth were randomly divided into 3 groups (n=10). initial surface roughness was measured at three different points with a profilometer and the average was obtained. sensodyne pronamel in group 1, oral b pro-expert stages in group 2 and elmex kinder-zahnpastai in group 3 were applied with charged toothbrush for 2 minutes, twice a day and a week. surface roughness was again measured after brushing. data were analyzed statistically. results: statistically significant difference was not found between the three groups in initial roughness values (0.47 μm, 0.48 μm ve 0.52 μm) and in roughness values after from brushing (0.52 μm, 0.54 μm ve 0.53 μm) (p>0.05). intra-group comparisons were no observed a statistically significant difference in first group (p=0.059) and third group (p=0.251), and was observed a statistically significant difference in second group (p=0.005). conclusion: all toothpastes used in this study caused acceptable surface roughness values. therefore, the use of three toothpastes in primary teeth are unobjectionable.
