title: [Correlation of bleached teeth's tissue micro-durability and time of placing the dental filling].
abstract: Bleaching of discolored teeth has become one of the pressing issues of modern aesthetic dentistry in Georgia. Correct selection of endo-bleaching substances is crucial in resolving this issue, as it is well known that endo-bleaching agents penetrate into the dental tissues, causing "microcracks". Aim of our study became selection of right materials for dental bleaching, as well as finding additional methods of prevention these materials from penetrating into the dental tissue. Serving this aim, we have studied several types of endo-bleaching substances, as well as micro-durability of dental tissue, based on the numerous methods of its determination. Subsequently we observed the effect of endo-bleaching materials "endoopalescence" and "endoperox" on dental tissue. Data analysis has shown that there were significantly less "microcracks" found after use of "endoopalescence", than "endoperox". The most beneficial results were obtained during concomitant use of endo-bleaching material "endoopalescence" and antioxidant, since the latter improves micro-durability of dental tissue. Based on all of the above we recommend use of "endoopalescence" as an endo-bleaching substance, in complex with antioxidants.
