Effect of Different Topical Fluoride on the Surface Roughness of Glass Ionomer Cement

Abstract

<div class="WordSection1"><p class="AbstractContent"><strong>Objective</strong>: To evaluate the effect of acidulated phosphate fluoride (APF) gel and sodium fluoride (NaF) gel on the surface roughness of glass ionomer cements.</p><p class="AbstractContent"><strong>Methods:</strong> Twenty disc-shaped samples were fabricated from glass ionomer cement (Fuji II, GC Gold Label, Japan) and divided into two test groups that is group I for acidulated phosphate fluoride (APF) gel application and group II for sodium fluoride (NaF) gel application. After 24 hours, the surface roughness (Ra) was determined using a profilometer (MarSurf M300, Germany). Samples surface were applied by topical fluoride gel according test group for 4 minutes. After the treatment, the surface roughness (Ra) was determined using a profilometer. T test was used to evaluate surface roughness measurement and the differences in surface roughness values between test groups.</p><p class="AbstractContent"><strong>Results</strong>: Acidulated phosphate fluoride gel group showed the highest surface roughness than sodium fluoride group. There were significant differences between test groups (<em>p</em> = 0.00).</p><p class="AbstractContent"><strong>Conclusion</strong>: Acidulated phosphate fluoride gel can cause surface roughness on the glass ionomer cement more than sodium fluoride gel.</p><div><p class="Keywords" align="left"><em>Keywords: acidulated phosphate fluoride, glass ionomer cements, sodium fluoride</em><em>, surface roughness</em><em></em></p></div></div><em><br clear="all" /></em>
