Internal bleaching effectively whitens nonvital teeth but can cause cervical resorption. This study presents an improved technique for internal bleaching and restoring the access cavity to mitigate risks.

Area of Science:

  • Dentistry
  • Endodontics
  • Restorative Dentistry

Background:

  • Internal bleaching, or "walking" bleaching, is a long-standing dental procedure for treating nonvital tooth discoloration.
  • While effective for color change, internal bleaching is linked to cervical resorption, a significant clinical concern.
  • Second-generation esthetic bonding materials are theoretically expected to improve the seal at the tooth-restorative interface, but evidence is limited.

Purpose of the Study:

  • To present a refined method for performing internal bleaching.
  • To describe a technique for restoring the access cavity following internal bleaching.
  • To address and potentially mitigate the risk of cervical resorption associated with internal bleaching.

Main Methods:

  • A detailed procedural description of the suggested internal bleaching technique.

Related Experiment Videos

  • Explanation of the restorative steps for sealing the access cavity post-bleaching.
  • Discussion of material selection and application for optimal interface sealing.

    • Main Results:

    • The proposed method aims for predictable color change while minimizing risks.
    • The technique focuses on achieving a superior seal at the tooth-restorative interface.
    • The presented approach is designed to prevent or reduce the incidence of cervical resorption.

    Conclusions:

    • Internal bleaching remains a viable option for nonvital tooth whitening.
    • The presented technique offers a potential solution to the problem of cervical resorption.
    • Improved restorative techniques are crucial for the long-term success of internal bleaching procedures.
