OZONE : A NEW TREND IN DENTURE CLEANSERS
A SHORT STUDY
Context: The use of denture cleansers significantly reduce the number of microorganisms on dentures but their effect on the physical properties of denture base are debatable.
Aim: The study was designed to compare and evaluate the hardness, flexural strength and surface roughness after treating heat activated acrylic resin specimens with different denture cleansers and ozone.
Material and Methods: 45 heat activated acrylic resin specimens were treated with three different denture cleansers Ozone (liquid dilution 1000ch SBL private limited) , Distilled water , Clinsodent (ICPA health products ltd) and immersed in the respective solution for seven days. The immersed heat activated acrylic resin specimens were evaluated for flexural strength, hardness and surface roughness.
Statistical Analysis: The statistical analysis was done using the non-parametric Kruskal Wallis test to compare means of the three different denture cleansers.
Results: The flexural strength of group C (Ozone) was significantly higher than that of the control group A (distilled water) and group B (Clinsodent). The surface roughness of group C (Ozone) was lower compared to control group A (Water) and group B (Clinsodent). The Hardness of Group C (Ozone) was higher followed by control Group A (Water), and then by Group B (Clinsodent) but the values were not statistically significant.
Conclusion: Ozone was found to have higher flexural strength, least surface roughness compared to Distilled water and Clinsodent with a statistically significant value. Whereas, the effect of ozone on hardness of heat activated acrylic resin specimens does not show any significance.
