Abstract

Introduction

Daily application of mouth rinses has been recommended for the prevention and control of caries and periodontal disease.

Aims & Objectives

The aim of this study was to evaluate the effect of alcohol-containing and alcohol-free mouth rinses on the microhardness of three restorative materials – resin composite (Filtek Z350XT), light cure glass ionomer cement (Vitremer) and conventional restorative glass ionomer cement (GC Fuji II).

Methods

Twenty samples of each restorative material were fabricated and their microhardness values were checked at 100g load and 15 seconds dwell time. Ten samples of each restorative material were stored in alcohol containing mouth rinse (Listerine) and ten samples each were stored in alcohol free mouth rinse (Hiora) for 12 hours. At the end of the test period microhardness was measured with a Vickers microhardness tester.

Results

Alcohol containing mouth rinses reduced the microhardness values of composite and light cure glass ionomer significantly more than alcohol free mouth rinses. Reduction in the microhardness value of conventional restorative glass ionomer cement was similar for both alcohol containing and alcohol free mouth rinses.

Conclusion

Both mouth rinses showed reduction in microhardness values of all three restorative materials, with more reduction caused due to alcohol containing mouth rinses in composite and light cure glass ionomer.
