Abstract.
Change and correction of teeth color is an urgent problem of modern dentistry. For pulpless teeth it is most advisable to use intracrown whitening by means of hydrogen peroxide, carbamide peroxide and sodium perborate. However, for today there are no published data about the material, that completely isolates the root of the tooth on whitening. So it is urgent to study the effectiveness of the use of different filling materials for the production of entrance insulating inlays.
Objectives. To evaluate micropermeability of the materials used for the manufacturing of entrance seals on intracrown whitening.
Material and methods. 122 specimens of 65 teeth served as an object of the research. To study as entrance seals «Ketac Fill Plus» (3M ESPE, USA); «Unitsem» (VladMiVa, Russia); «RelayX U200» (3M ESPE, USA); «Fudji ll LC» (GC, Japan) were selected. The obturation of root canals was done by the lateral condensation method using the sealer «Viedent» based on epoxide resin and the sealer «Eodent» based on eugenol (VladMiVa, Russia).
Results. The lowest values of the dye penetration in the hard tissues of the tooth at the border «entrance filling/root canal» were observed when using self-adhesive luting cement «RelayX U200» and they amounted to 0,31+0,12 points (p=0,036). While using glass ionomer cements «Fudji ll LC» and «Ketac Fill Plus» the degree of dye penetration made up 0,81+0,25 and 1,0+0,29 points, respectively. Zinc phosphate cement «Unitsem» demonstrated low hermetic capacity – 1,93+0,36 points (p=0,036).
Conclusions. The results of the conducted study suggest that the best insulating capacity as an entrance seal was shown by self-adhesive self-etching cement, so it can be recommended for the entrance obturation on intracrown whitening.
Zinc phosphate cement of chemical curing demonstrated poor sealing capacity and its use as an entrance seal is undesirable during the internal bleaching.
Key words: micropermeability, entrance seal, intracrown whitening.
