The consumption of edible products strongly recommends the regular hygiene of oral cavity. Various dental products of allopathic and herbal origin are used as dentifrices. The dentifrices are considered safe and effective in terms of cleansing effect of oral cavity and antimicrobial effect against microbes causing bad smell and diseases such as gingivitis, pyorrhea etc. These characteristics of preparations are basically related to physicochemical properties of ingredients present in their composition and some how on directions of their use. In the present study, the marketed allopathic dentifrices coded as Brand I and II and herbal tooth powders coded as Brand III and IV were selected to analyze the impact of physicochemical properties of incorporated ingredients on their cleansing efficiency. The physicochemical characteristics studied were pH, bulk volume, tapped volume, tapped density, bulk density, true density, porosity, flowability, compressibility, compactability, cohesiveness, dispersability, Carr’s index, Hausner’s ratio, water soluble content, alcohol soluble content, foaming index, particle rearrangement behaviour and particle rearrangement constant. The antimicrobial effect of these powders was studied against Staphylococcus sorbinus, Staphylococcus salivarius and Lactobacillus acidophilus. It was observed that some of the physicochemical properties of all powders were different from each other. Marked antimicrobial effect of tooth powders was observed against pathogens. In all preparations, remarkable foaming index was analyzed that was generally considered responsible for cleansing effect.
