Abstract

Background: The objectives of this study are to evaluate the effect of addition of Multi-Wall Carbon Nano Tubes (MWCNTs) of different concentrations (0.05 mg.mL-1,0.25 mg.mL-1,0.5 mg.mL-1and1 mg.mL-1) on dimethyl sulphoxide DMSO and distilled water (DW) on tooth enamel. It intends to evaluate enamel microhardness in (Kg. m-2) pre and post the application of Multi-Wall Carbon Nano Tubes (MWCNTs).
Materials and Methods: Thirty specimens prepared for the present study to measure the hardness of the enamel.
Results: The results showed that a significant increase in the enamel microhardness for groups 0.05 mg/mL (group B), 0.25 mg/mL (group C), 0.5 mg/mL (group D) and 1 mg/mL (group E) compared with control group (group A) in dimethyl sulphoxide media. Also, the results showed a significant increase in the enamel microhardness for polished samples compared with unpolished samples in DMSO media.
Conclusion: The final conclusion highest mean value obtained was 1 mg/mL (group E) in the enamel microhardness suspension in and dimethyl sulphoxide media.
Key words: Multi-Wall Carbon Nano Tubes, enamel hardness.
