Abstract :Discoloration in non-vital teeth poses a significant clinical problem in terms of aesthetic concerns and patient satisfaction. Intracoronal bleaching is one of the most frequently preferred methods for managing this condition. Also known as internal bleaching, this technique preserves tooth tissue thanks to its minimally invasive approach. Currently used bleaching agents are predominantly peroxide-releasing compounds such as hydrogen peroxide, carbamide peroxide, and sodium perborate. In recent years, current methods such as LED-assisted activation, laser-assisted activation, non-thermal plasma, and ultrasonic activation have been included in research to increase bleaching effectiveness. However, the success of the applied protocols depends on many factors, such as the etiology of the discoloration, agent selection, application time, and application method. During the bleaching process, changes that may occur in the enamel and dentin structure, possible adverse effects on adhesive bonding, and the risk of cervical root resorption, which is one of the complications, should be carefully evaluated. In this review, current techniques for intracoronal bleaching in non-vital teeth, materials used, application methods, success rates and possible complications are discussed in line with the current literature. In addition, clinicians are provided with recommendations to be careful during application and to increase patient safety. The information obtained aims to guide a safe and effective bleaching process in clinical practice.
