Abstract Fluoride dentifrices are considered to be mainly responsible for decline in dental caries observed in last decades either in developed or developing countries. To compare fluoride concentration in saliva after teeth brushing using dentifrices with different types and concentrations of fluoride. Seventy five children ranging in age from eight to ten years were randomly divided into five groups according to type of dentifrice used (NaF 500ppm, NaF 1450ppm, SMFP 500ppm, SMFP 1450ppm and non - fluoridated dentifrice). Salivary fluoride levels prior to brushing, 5, 30 and 60 minutes after brushing were estimated. For all groups, there was significant increase in mean fluoride concentration after 5 minutes. from 5 to 30 minutes, significant decrease occurs. Further significant decrease was observed from 30 to 60 minutes. After 5 minutes, (NaF 1450 ppm) showed the highest mean fluoride concentration then (SMFP 1450 ppm) this was followed by (NaF 500 ppm) then (SMFP 500 ppm) and finally control group was the lowest .After brushing, there is positive correlation between fluoride concentration of dentifrice and the salivary fluoride level |
