[Comparative investigations on toothpastes]

A comparative study was carried out of the clinical usefulness and properties of two types (differing in the type of chalk used) of the following toothpastes: Nivea, Herbena, Salodent and four various Fluorodent toothpastes (differing in the type of calcium carbonate and thickener). The study was carried out on 100 students of the first classes of the Economics College in Poznań. The obtained results of clinical investigations justify the replacement (in part at least) in the production of toothpastes of the imported chalk Socal with Polish chalk from Janikowo.
