Summary

<span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>Total etch dentin bonding agents had been used extensively in operative dentistry. These materials were used on dentin surfaces </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>before application of the resin adhesive restorative. The purpose of this research was to prove the difference of tensile bond strength </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>between total etch and self etch dentin bonding agent on dentin surface. The manner of preparing total etch dentin bonding agent </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>was : bovine dentin as sample was grounded to give flat surface which was then etched with 37% phosphoric acid for 15 seconds, </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>washed with 20 ml water and dried with blot dry technique. Sample was placed in a desiccator for one hour 60% humidity covered </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>with bonding agent and put into tensile tool plunger and stored at room temperature (</em><span style="font-family: Symbol; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">± <span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>28 °C) for 24 hours. Sample was tested using </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>Autograph instrument. The manner of preparing self etch dentin bonding was equal with total etch manner but without acid etching, </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>washing and drying. The data analyzed using One-Way ANOVA test at </em><span style="font-family: SymbolProportionalBT-Regular; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">α <span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>= 0.05 and followed Tukey HSD test. The result indicated </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>that the tensile bond strength of total etch was higher than self etch dentin bonding at 60% humidity (p </em><span style="font-family: SymbolProportionalBT-Regular; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">≤ <span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>0.05). In conclusion, the total </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>etch dentin bonding agent with acetone solvents have a higher tensile bond strength compared with self etch dentin bonding agent also </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>with dentin bonding in alcohol solvents.</em></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span>
