title: [Influence of whitening endoopalescence systems on the restoration of devitalized teeth].
abstract: At the end 80s of the XX century bleaching of teeth became one of the most important issues in the stomatological industry. Currently there are two methods of bleaching: external and internal (endo bleaching) methods. It is proved that the adhesive ability of the tooth tissues reduces as a result of peroxide penetration into enamel and dentine. Based on this, the aim of our study was to use the antioxidants for excluding the peroxides from tooth tissues and for rehabilitation of reduced adhesion. For this purpose we used central and side 36 healthy incisors, where after processing of tooth tissue with antioxidants and without them we studied the formation of micro rift between the operation material and dentine, and intensity of micro flowing by means of stereo microscope. We used 30% endo-opalescence as a bleacher and used 10% sodium acrobat as antioxidant. As a result of experiment we found out that the teeth where we used antioxidant were not penetrated with metaline blue; unlikely, the teeth where we did not use the same method we got the approximate result in the group of teeth, where for peroxide exclusion we performed the crown reconstruction not immediately, but after 7 days. During the whole experiment the teeth were kept in thermostat at 37 degrees C in saliva to create the natural conditions for them. In overall we can conclude that the deteriorated adhesive ability with peroxide influence can be improved by application of antioxidants.
