An Invitro Study into the Effect of two Denture Cleaners on Surface Roughness of Acrylic Dentures |
|
| چکیده انگلیسی مقاله |
Statement of Problem: Utilization of denture cleaning solutions and toothpastes are common methods of cleaning the denture surfaces, which can increase the surface roughness of acrylic dentures. Purpose: The aim of this study was to evaluate the effect of two cleaning agents in the form of solution and paste on the surface roughness value of denture following tooth brush application. Materials and Method: Thirty acrylic discs with 20 mm diameter and 2 mm thickness were made and uniformly polished. These discs were randomly divided into three groups, each comprising ten discs. The roughness value (Ra) was measured, using talysurf.10. The discs in the first group were brushed using tooth paste and brush. The discs in the second group were first brushed using water and tooth brush, and then immersed in cleaning solution for 92 hours. The discs in the third group (control) were only brushed using water and tooth brush. For all the groups, tooth brushing abrasion test was performed with 200gr weight applied. The surface roughness of each specimen after 10.000 strokes was determined. Data were analyzed with ANOVA and post hoc Tukey test (α =0.05). Results: An increase in the surface roughness was observed for all groups. However, surface roughness in the first group, for which tooth paste had been used was significantly increased as compared to the other groups ( p =0.01). But there was no significant difference between the other two groups ( p >0.05). Conclusion: Denture cleaning materials in the form of solution produce less surface roughness as compared to the ones in the form of pastes. |
