The ability of the material to inhibit the phenomenon of secondary
caries depends on several factors among them being forming an intimate
connection between filling and the surface of the tooth as well as
capability of the material to release caries protective agentsas the
fluoride happens to being the neighboring and surrounding dental
structures. The goal of the work is to determine the increase of the
fluoride concentration in the dentinein a 6 weeks periodic case of
permanent teeth being renovated by means of three different restorative
materials, which according to the producer’s recommendations are
consisted of and release fluoride for a longer period of time. Two of
them belong to the group of glass ionomer cements like Fuji II LC
(GCTokyo, Japan) resinous modified glass ionomer cements while the third
one is a composite Tetric Ceram (Ivoclar,Vivadent). The examination was
performed on extracted impacted third molars of patients the age being
30 to 40. The incorporated fluoride concentration has been determined by
significant increase of spectrometer Perkin Elmer 50 at the Faculty of
Mathematics and Natural Science in Skopje.
The results of our examination reveled statistically significant
increase of the fluoride concentration in the dentine after applying
filling in all three tested materials. The analysis of the results
regarding implementation of the fluoride in the dentin showed that the
incorporated fluoride quantity in the dentin was highest after applying
Chemfil superior and lowest in case of applying Fuji II LC.
