Effect of salvadora Persica Extracts on Titanium Alloy Surface Topography

Abstract

Introduction:Fluoride containing mouth rinses, and toothpastes have been reported to decreasethe corrosion resistance of titanium.Salvadora persica has been recently introduced in twoforms: tooth paste (Saudi Arabia) and mouth wash. The influence of these products on TitaniumAlloy Surface Topography has not been tested before. Aim of the study: To compare betweenthe effects of Salvadora persica(Siwak® toothpaste and its alcoholic extract), with fluoridecontaining tooth paste (kin® toothpaste) and kin® mouth wash on the corrosion of pure titaniumgrade 2 (cpTi). Materials and methods: Alcoholic extract of Salvadora persicawas prepared,and tested on sixty weighted samples of cpTi divided into 4 experimental groups. Samples in thecontrol group were immersed in distilled water. In the first experimental group, samples weretreated with Kin® tooth paste. For the 2nd experimental group, samples treated with Kin® mouthwash. Samples in the 3rd experimental group were treated with Siwak® toothpaste. The finalexperimental group was treated with extract of Salvadora persica. These samples were subjectedto surface topography (AFM) and transverse strength tests before, after three, and six months oftreatments. Results: Weighting test showed no significant difference (p≤0.05) between the meanvalues of four treated groups of cpTi samples before, and after 3 months. However, there was asignificant difference (p<0.05)between cpTi before and after 6 months treatment with Siwak®tooth paste. Surface topography showed a statistically significant difference between root meansquare roughnesses of cpTi samples after 3, and 6 months of treatment. Transverse strength alsoshowed a statistically significant difference between the mean value of cpTi between the treatedand control groups after three months and six months.Conclusions:Siwak® toothpaste seems to have more effect on both weight and roughness of cpTicompared to alcohol extract of Salvadora persicaand Kin® toothpaste.
