Determination of Fluoride Ion Concentration in Tooth Powder Sample by Designing and Developing of PC based Instrumentation

Dr P. Saraswathi | Dr N. Vijayalakshmi | P. Suryanagi Reddy | B. Vani Sree


Abstract: Several Indian fluoride dentifrices have in their packages as non – fluoridated tooth powders and also in their formulations calcium phosphate as abrasive, which may react with fluoride. The decline of dental caries in the industrialised countries can be attributed to wide spread use of fluorides. The Indian market share of dentifrices containing fluorides has increased day to day. This study was designed to evaluate the determination of fluoride ion concentration in certain tooth powder using the PC in the most consumed dentifrices in India. The fluoride ion concentration in certain tooth powder was determined using the spectroscopic method and by using the PC. All dentifrices showed similar concentrations of total fluoride in all samples in accordance with the Indian legislation (content of 1000 ppm F). In this study most of the Indian fluoridated dentifrices evaluated and they were found to have sufficient concentrations of fluoride ion to be effective in preventing dental caries.
