The effect of different mouth rinses on Micro-hardness of tooth-colored restorative materials.
J Pak Dent Assoc Jan ;14(3):150-3.

OBJECTIVE: The aim of this study was to investigate the effect of commercially available mouthrinses on the microhardness of different esthetic restorative materials. MATERIALS & METHODS: Seventy-two specimens fabricated for the three restorative materials, resin composite (Point 4), Ormocer (Admira) and Compomer (Dyract AP), (24 each) using plastic mold (3 X 8mm) and initially stored in distilled water for 24 hours at room temperature. The specimens were then randomly divided into four equal groups and exposed to the following solutions for 24 hours at 37C: Listerine (alcohol-containing mouthrinse), Orasept (alcohol-free mouthrinse), Emufluor (alcohol-free fluoride containing mouthrinse), and distilled water (control). After conditioning, the specimens were subjected to Vickers surface hardness investigation (load= 300g; dwell time =15 seconds). RESULTS: Data was analyzed using ANOVA and Tukey`s HSD multiple range test at significance level of 0.05 (P 0.05). All the restorative materials were significantly soften by Listerine alcohol-containing mouthrinse and show reduction in surface hardness, while there were no significant differences by other conditioner. CONCLUSION: Using the alcohol-free mouthrinses and alcohol-free fluoride mouthrinses are advocated.
