An Investigation of the Effect of Cleaning Solutions on Plaque Removal, Surface Roughness and Hardness of Oral Appliances
Abstract
Purpose: The purpose of this in vitro study was to compare the effectiveness of cleaning solutions on bacterial plaque removal and changes in surface roughness and hardness of the oral appliances. Material and Methods: After Proform Soft EVA and Essix A+ specimens (n=96 each) were immersed inartificial saliva with Streptococcus mutans for eight hours, the following cleaning steps were applied daily at room temperature for 15 days, using Dawn dish soap, Listerine antiseptic mouth rinse, Retainer Brite tablet, or TheraBreath mouth rinse: Treatment (1) Cleaning solutions for 16 hours (as a positive control), (2) Cleaning solutions for 10 min and bench dry for 16 hours, (3) Cleaning solutions for 10 min and immersed in water for 16 hours, and (4) Immersed in water for 16 hours (as a negative control).Results: Type of cleaning solution had significant effect on surface roughness (p=0.0145). Dawn caused a significant decrease in roughness when compared to Listerine or TheraBreath, which caused a significant increase (p < 0.05). Type of cleaning solution and treatment had a significant effect on hardness (p=0.001). Listerine caused the most variation and TheraBreath caused a decrease in hardness regardless of the treatment type. The overall mean for the change in bacterial growth of TheraBreath was greater than other cleaning agents, and the significant interaction effect indicates that Treatment 2yielded the most bacterial growth with TheraBreath. Conclusion: Dawn caused the least changes in roughness and hardness of the oral appliances, and still had good antibacterial properties. Listerine can be a good antibacterial solution but may affect structural longevity of the prosthesis. TheraBreath may need to be re-considered as an antiseptic solution.
