Effect of Different Natural Herbal Products on Microhardness of Eroded Enamel Surface: An in Vitro Study by Zeina Samir, Aisha Akram Qasim

“…The Microhardness of enamel blocks was measured before and after the PH cycle by using a Vickers microhardness measurement machine. Results: The microhardness of enamel surface in all study groups was decreased after eroding Pepsi drink due to the demineralization, then increased after treatment with remineralizing agents but the highest increase of the surface microhardness measurements belonged to the Ginger+Manuka group followed by Neem and NaF group, while the control negative group of deionized water which not exposed to Pepsi drink had the minimum decrease in the surface microhardness measurements. …”

The Effects of Two Root Canal Irrigants and Different Instruments on Dentin Microhardness ( In Vitro Study) by Wiaam MO AL-Ashou

“…Materials & methods: The teeth divided in to four groups according to the type of irrigating solutions that used during root canal instrumentation with the use of normal saline as a control group, then each group sub divided in groups according to the instrument used in the root canal preparation, then after irrigation and preparation the roots sliced and root dentin microhardness measured using Vicker,s microhardness machine. Results: The result of this study showed that the type of instrument and Chlorhexidine have no effect on the microhardness of root canal dentin while Sodium Hypochlorite significantly decrease the microhardness of root canal dentin especially when use with Stainless Steel K-files and Nickel-Titanium K-files than when used with rotary Nickel-Titanium files. …”
