Abstract

Objectives: The aim of this study was test the effect of mouthwashes with different pH on sorption and solubility of nano-filled composite resin restorative materials.

Materials and Methods: 56 cylindrical specimens were prepared from 2 types of nanofilled composite resins, 28 specimens from each material. Specimens of each type of composite were randomly divided into four groups (n = 7). 7 specimens were used as a control group immersed in distilled water. The other 3 groups were stored in the following mouth washes (Avohex, Listerine and Parodontax) for seven days. Specimens were dried in desiccator to a constant weight before immersion. The immersion media were changed daily for 7 days, waived in air and weighted to calculate the amount of sorption. Specimens were dried again and reweighted to calculate the amount of solubility. Sorption and solubility tests were made using electronic balance.

Results: Both composite resins showed varying degrees of water sorption and solubility in all storage media. SDI ice composite resin showed higher water sorption in Listerine and lower in Avohex mouth washes. SDI Ice nanohybrid composite resin showed higher solubility in Avohex mouth wash and lower solubility in distilled water. Charisma nanohybrid composite resin showed higher water sorption in Avohex mouth wash and lower in distilled water. Listerine and Parodontax mouthwashes showed intermediate comparable values. Charisma nanohybrid composite resin showed higher solubility in distilled water and lower in Listerine mouthwash. Listerine and Parodontax mouth washes had intermediate effects of sorption and solubility on both types of composite resins.

Conclusion: All tested nanofilled composite resins showed varying degrees of water sorption and solubility in all storage media. SDI ice composite resin showed higher water sorption in Listerine and higher solubility in Avohex mouthwashes. It exhibited lower sorption in Avohex mouth wash and lower solubility in distilled water. Charisma nanohybrid composite resin composite resin showed higher water sorption in Avohex and higher solubility in distilled water. It demonstrated lower sorption in distilled water and lower solubility in Avohex mouth wash.
