| Summary: | Background. The disinfection of orthodontic acrylic resins might change the physical and mechanicalproperties of these materials. We aimed to investigate the impact of four different commercially availabledisinfectants on the surface roughness of acrylic resins used for orthodontic appliances. Methods. Four disinfectant solutions (BirexSE, Opti-Cide3, COEfect MinuteSpray, and CaviCideSpray) were used to disinfect orthodontic acrylic resins using the spraying method. The resins weresubjected to repeated disinfection protocols. Distilled water, also applied via spraying method, was usedas a control. Surface roughness was scrutinized to examine the extent of surface topography changes bystylus profilometry. Data normality was evaluated via the Shapiro–Wilk test, followed by the WilcoxonSigned-Rank test for non-parametric data or paired Student’s t-test for parametric data to compareintra-group differences in roughness before and after the use of the disinfectant solutions. Results. Some of the disinfectants (BirexSE and CaviCide) resulted in significant changes in surfaceroughness values before and after the disinfection compared to the controls (P<0.05). The groups thatwere in contact with distilled water, Opti-Cide, and Coeffect did not exhibit significant differences insurface roughness before and after the intervention (P>0.05). However, from a clinical perspective, theresulting variations in surface roughness (<%0.15) induced by these solutions might not reflect clinicallysignificant differences. Conclusion. The use of disinfectant solutions is unlikely to harm the surface of orthodontic acrylic resins.Oral care providers need to be attentive to the interpretation and implementation of clinically significantchanges in their evidence-based approach regarding potential material damages by disinfection sprays. |
