The comparison study of Fluoride kinetics in saliva after the use of chewing gums containing different fluoride compounds In Iraqi subjects

Abstract

There is a relationship between the use of fluoride, the reduction of dentalcaries and the increase of dental fluorosis. The purpose of this study was toanalyze the fluoride kinetics in saliva after using two commercially availablechewing gums with fluoride, which contains (3.38) mg of fluoride as marketedSodium monofluorophosphate (NaMFP) and sodium fluoride (NaF) which arethe two most common sources of fluoride used in currently fluoride dentifrices.Fifteen 7-9 year-old volunteers were instructed to chew the fluoridatedgums. Total saliva was collected, at 0, 3, 6, 9 and 15 minutes after 3 minutesstarting chewing. Salivary fluoride was analyzed with a fluoride-specificelectrode (201 Fluoride E. HANNA instruments) after acid hydrolysis.The fluoride amount in the saliva samples after the use of chewing gumwhich contains Sodium monofluorophosphate (NaMFP) was 0.4 mg whichhigher than after the use of chewing gum contains sodium fluoride (NaF) whichwas 0.041mg in all experimental periods,The high fluoride presence in saliva after the use of chewing gum of(NaMFP) is significant to prevent dental caries and this should be evaluated inclinical researches. On the other hand, children at an age of risk for dentalfluorosis should avoid the use of this kind of chewing gums.
