Photographic assessment of the antiplaque properties of sanguinarine and chlorhexidine

Abstract

The purpose of this study was to assess the effect of rinsing and topical application of sanguinarine on labial surface plaque accumulation, compared with topically applied water, and compared with rinsing with chlorhexidine, while refraining from all oral hygiene measures for 5 days. Color photographs of the disclosed plaque were taken at the end of each phase of treatment and blindly traced using an Apple II micro-computer graphic tablet digitizer. The plaque score for each tooth was calculated by dividing the computer reading of the labial plaque surface area by the total labial surface area of the tooth. Topically applied sanguinarine showed better plaque reduction than mouthrinsing with sanguinarine. There was a significant reduction in plaque accumulation after rinsing with chlorhexidine compared with topically applied sanguinarine, water, and mouthrinsing with sanguinarine. The results of this study indicate that chlorhexidine is a more superior antiplaque agent than sanguinarine. The use of an Apple II micro-computer graphic tablet digitizer provided a valuable method for accurate plaque assessments.

Atividade Antimicrobiana e Antiaderente do Extrato da Mimosa tenuiflora (Willd). Poir. Sobre Microrganismos do Biofilme Dentário

“…Este fato ocorre devido a sua liberação lenta na cavidade bucal, e consequentemente a sua ação inibidora sobre as enzimas glicosídicas e proteolíti cas 13,14 . Os dados obti dos demonstram a efi cácia do extrato da jurema preta quando comparado aos obti dos pelo gluconato de clorexidina, mostrando a potencialidade de ambas as substâncias como agentes anti microbianos efi cazes sobre os microrganismos do biofi lme dental.…”

The finding of antiplaque features in Acacia Arabica type of chewing gum

“…The participants used Acacia gum and sugar free gum in a similar cross-over design as in trial one. 2 colored photographs, one for the right and the other for the left upper and lower anterior teeth, were taken of the erythrocine-disclosed plaque from a fixed distance (Gazi 1988). The photographs were taken daily at noon from the 2nd day onward.…”
