In-Vitro Comparison of Radicular Penetration of Hydrogen Peroxide Among Different Intracoronal Bleaching Agents

INTRODUCTION: In this study, intracoronal bleaching, which is a conservative treatment approach hydrogen peroxide to the cervical region from different bleaching agents used in penetration was aimed to be compared. METHODS: In our study, 60 single-rooted maxillary incisors were used. After root canal treatment procedures, the gutta percha canal filling was removed 4 mm below the enamel-cementum junction. Glass as a protective barrier ionomer cement was placed 2 mm below the enamel-cementum junction. RESULTS: The difference between day 1 and day 3 hydrogen peroxide uptake of the Whiteness SuperEndo group was statistically significant. not found to be significant (p>0.05), but in the other experimental groups on days 1, 3 and 7 the difference between hydrogen peroxide uptake amounts was statistically significant was observed (p < 0.05). DISCUSSION AND CONCLUSION: High levels of radicular hydrogen peroxide to minimize the risk of cervical root resorption sodium perborate + distilled sodium perborate as a good alternative to penetrating bleaching agents water mixture and carbamide peroxide gels. Also the use of carbamide peroxide gel sodium peroxide because of its ease and the fact that it is as effective as hydrogen peroxide in studies we can say that it is a good alternative to a mixture of perborate + distilled water.
