Comparative Evaluatoin of Surface Roughness of Herbal Denture Cleansing Tablet containing Essential Oils of Tulsi and Lemongrass,0.12% Clorhexidine Diguleconate and Commercially available denture cleansing tablet on Heat cure Polymethyl Methacrylate Denture Base Resin: An Invitro Study.

Abstract

STATEMENT OF PROBLEM Poor denture hygiene is a risk factor for oral infections and systemic

dissemination. Denture cleanliness is essential to prevent malodor, poor aesthetics and the accumulation of plaque/calculus with its deleterious effect on the mucosa. Denture base resins become colonized by several microbial species in the oral cavity. There are number of tablets, pastes and powders available for cleaning dentures with a variety of manufacturer’s claims for their relative efficacies. Due to increase in the use of denture cleaners can lead to more wear off of the heat cure polymethyl surface leading to surface roughness.

The increase in the surface roughness of the heat cure polymethyl methacrylate can lead to increase in denture biofilm. Candida species yeasts are the most common species associated with denture biofilm. Streptococcus mutans and other bacterial species are also important denture biofilm components.

PURPOSE The purpose of this study was to evaluate and compare the surface roughness of herbal denture cleansing tablet containing essential oils of tulsi and lemongrass, commercially available denture cleansing tablet and 0.12% chlorhexidine digluconate on heat cure polymethyl methacrylate denture base resins
