| Abstract: | Objective To measure the fluoride levels in dental plaque and saliva following the bonding of fluoridereleasing orthodontic brackets.Methods Fluoride ion-specific electrode was used to determine the fluoride concentrations in dental plaque and saliva of 10 volunteers who used the fluoride-releasing orthodontic brackets.The fluoride concentrations were then compared with baseline.Results The fluoride concentrations in dental plaque and saliva were significantly higher compared with base line.The higher fluoride levels lasted for 3 days in saliva and for 18 days in dental plaque.Conclusion The fluoride levels in dental plaque and saliva increased after the bonding of fluoride-releasing orthodontic brackets,which may play a role in preventing decalcification of enamel. |
