Ali عباس فاضل علي}, journal={Journal of baghdad college of dentistry مجلة كلية طب الاسنان بغداد}, volume={28}, number={1}, pages={169-173}, year={2016}, 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 sulphoxideDMSO and distilled water (DW) on tooth enamel. It intends to evaluate enamel microhardness in (Kg. m-2) pre andpost 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) indimethyl sulphoxide media. Also, the results showed a significant increase in the enamel microhardness for polishedsamples compared with unpolished samples in DMSO media.Conclusion: The final conclusion highest mean value obtained was 1 mg/mL (group E) in the enamel microhardnesssuspension in and dimethyl sulphoxide media.
