| Abstract | ||||
| This study evaluated the effects of charcoal toothpaste on the microhardness and surface roughness of nanofilled, micro hybrid resin composite and resin modified glass ionomer. A total of 120 samples (40 samples per each material). Group A: forty samples were fabricated from Z350 XT (nanofilled) resin composite samples. Group B: forty samples were fabricated from a Z250 (micro filled) resin composite. Group C: forty samples were fabricated from Fuji II. The samples of each group were divided into 2 halves (n=20) according to the testing method microhardness and surface roughness (Ra) then subdivided according to toothpaste used close up diamond attraction (charcoal) and close up everfresh (conventional) into 2 halves (n=10). All groups showed a decrease in surface microhardness with no statistically significant difference between groups A and B (p> 0.05), while Group C showed the highest reduction in surface microhardness with a statistically significant effect (p < 0.05). All tested groups showed an increase in the surface roughness values, while Group A recorded the least change in surface roughness (0.215), followed by Group B (0.269), and then Group C (0.320). Charcoal-based toothpaste decreased surface microhardness and increased the surface roughness of the three restorative materials compared to conventional toothpastes. | ||||
