Effects of different saliva pH on hybrid composite resin surface roughnes

---

Background: Currently, hybrid composite resin is the mostly used fi lling material to restore esthetic and function. During function, this material is in contact with various pH from food consumption, which is acidic and alkali which may effect the physical properties of composite resin, including surface roughness. Purpose: The research was conducted to determine the effect of pH in saliva on surface roughness of hybrid composite resin. Methods: This research used artifi cial saliva and composite resin samples divided into 3 groups based on different pH of immersion (pH 4, pH 7 and pH 10) for 30 days. Results: There were signifi cant differences (p > 0.05) among those three treatment groups of hybrid composites soaked in artifi cial saliva with different pH for 30 days. And, with LSD test it is also known that there were signifi cant differences between the artifi cial saliva with pH 4 and pH 7, whereas there was no signifi cant difference between pH 4 and pH 10 and between pH 7 and pH 10. Conclusion: It can concluded that the changes of salivary pH affect the surface roughness of the hybrid composite resin. Acidic pH has increase the surface roughness of hybrid composite resin, whereas alkaline pH has no effects on the surface roughness of hybrid composite resin, whereas alkaline pH has no effects on the surfaface roughness of hybrid composite resin
