Application of a tooth-surface coating material containing pre-reacted glass-ionomer fillers for caries prevention
Abstract
Purpose
Several
methods have been used to prevent dental caries, including fluoride
application to strengthen teeth and promote remineralization and the use
of sealants to fill pits and fissures in pediatric dentistry. However,
none of these methods alone can be considered a perfect preventive
treatment. For caries prevention, we evaluated pre-reacted glass-ionomer
(PRG) Barrier Coat (Shofu Inc., Kyoto, Japan), a tooth-surface coating
material developed using PRG technology that contains high levels of
controlled-release fluoride.
Methods
The
tooth-surface coating material was applied clinically as a new method
of preventing dental caries. Its effect on plaque adhesion, along with
its preventive effect on dental caries was investigated in actual cases
treated in a pediatric dentistry department of a university hospital.
Results
PRG
Barrier Coat was shown to have suitable adhesive strength and to be a
safe material that does not fracture the adherend. Actual ion release
and acid buffering were confirmed, and when clinically applied,
continuous fluoride release and recharge occurred, as did the release of
the other ions. This suggests that this material promoted dentin
remineralization, suppressed plaque adherence, and had a preventive
effect on dental caries.
Conclusion
This
material promoted enamel remineralization, suppressed plaque adherence,
and had a preventive effect on dental caries. These results suggest
that this coating material is appropriate for young children at high
risk of dental caries.
