The effectivity of tobacco leaf paste as denture cleanser to surface roughness of heat cured acrylic resin

Efektivitas pasta daun tembakau sebagai pembersih gigi tiruan terhadap kekasaran permukaan resin akrilik polimerisasi panas

Abstract

Microporosity of acrylic resin can facilitate the colonization of microorganisms, causing denture stomatitis. Mechanical clean-ing of dentures is effective for removing adhering microorganisms and plaque; electric toothbrush and denture cleaning paste. Using natural materials such as tobacco leaves is useful for minimizing the abrasive materials that can decrease surface rough-ness. The aim of this study was to determine the effectiveness of using tobacco leaf paste as denture cleanser to surface roughness of heat cured acrylic resin (HCAR). This experimental laboratory study and the posttest only control group design used 36 sam-ples (65x10x2.5) mm, divided into 4 groups: control group is brushed without paste, group A brushed with HPAI herbal tooth-paste, group B brushed with 50% tobacco leaf paste, and group C brushed with 75% TLP. It was showed that TLP was less ef-fective as denture cleanser to surface roughness of HCAR. A 75% TLP recommended as denture cleaning paste.
