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 dental caries and the increase of dental fluorosis. The purpose of this study was to analyze the fluoride kinetics in saliva after using two commercially available chewing gums with fluoride, which contains (3.38) mg of fluoride as marketed Sodium monofluorophosphate (NaMFP) and sodium fluoride (NaF) which are the two most common sources of fluoride used in currently fluoride dentifrices.
Fifteen 7-9 year-old volunteers were instructed to chew the fluoridated gums. Total saliva was collected, at 0, 3, 6, 9 and 15 minutes after 3 minutes starting chewing. Salivary fluoride was analyzed with a fluoride-specific electrode (201 Fluoride E. HANNA instruments) after acid hydrolysis.
The fluoride amount in the saliva samples after the use of chewing gum which contains Sodium monofluorophosphate (NaMFP) was 0.4 mg which higher than after the use of chewing gum contains sodium fluoride (NaF) which was 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 in clinical researches. On the other hand, children at an age of risk for dental fluorosis should avoid the use of this kind of chewing gums.
