Daftar Isi:
- Denture wearing is necessary when someone has lost their teeth. After an acrylic resin denture was used, a coating of biofilm will develop, therefore, denture cleansing is an essential way to prevent biofilm formation. The methods for cleansing dentures can be divided into mechanical, chemical, and combination method. The disadvantage is, that methods can cause the surface of denture base acrylic resin become rough. The purpose of this study was to determine the effect of denture cleansing methods in surface roughness of heat cured acrylic resin denture base. The methods of this study was experimental laboratory. Twenty seven disc of heat cured acrylic resin (10 x 2 mm) were divided into three groups, brushed using tooth paste (mechanical), soaked in denture cleanser solution (chemical), and soaked in denture cleanser solution then brushed (combination). After that, the increasing value of the surface roughness was measured using surface roughness measuring instrument (surfcom 120A). The data obtained were analyzed using oneway anova. Oneway anova test showed p<0.05 that means there was significant influence between the cleansing methods with surface roughness of heat cured acrylic resin denture base. LSD test showed that there was significant difference between mechanical method with chemical and combination methods (p<0.05), while there was no significant difference between chemical and combination methods (p>0.05). In conclusions, denture cleansing methods affect the surface roughness of heat cured acrylic resin denture base. The highest increasing value of surface roughness found in mechanical methods, but the value of the roughness is still within the tolerance limits (<2 Î1⁄4m).
