Abstract

Aim: The aim of the study was to evaluate and assess the resultant surface roughness of bulk-fill composite resin after duplication of daily brushing with different pastes like herbal and desensitizing formulation.

Materials and methods: In this study two different commercially available bulk fill composite resin materials were evaluated. One brand was Swisstec and the other brand was Tetric N-ceram. 8 circular moulds were made with 10mm diameter with uniform thickness and polished with polishing burs. Eight disc designed samples were accommodated in a simulator which reproduces the brushing cycles (ZM3.8 SD Mechatronik). 4 of the samples were cleansed and brushed with the Dabur- red herbal formulation toothpaste (Group 1) and another 4 samples were cleansed and brushed with sensodyne desensitizing formulation toothpaste (Group 2). Surface roughness was checked before and after the brushing simulation using a profilometer stylus (Mitutoyo SJ 310). The Ra values, the Rq values and Rz values for the composite blocks was evaluated.

Results: SPSS software version 23 was used and independent t-test was done for intergroup comparison analysis. Significance values for Ra, Rq and Rz are 0.356, 0.024, 0.902. Rq value was statistically significant.

Conclusion: It was concluded that increased surface roughness was observed for bulk-fill composite resin blocks brushed with herbal based toothpaste when compared with desensitizing toothpaste. Thus, use of herbal toothpaste can affect the surface roughness properties of composite resin.
