Intracoronal tooth bleaching - A review and treatment guidelines

Area of Science:

• Dentistry
• Dental Materials Science

Background:

• Intracoronal bleaching, a conservative dental procedure, has been used since the 19th century to improve tooth color.
• It remains popular for treating internal tooth discoloration due to its minimally invasive nature.
• Various materials and techniques have evolved to optimize results and mitigate risks.

Purpose of the Study:

• To review the contemporary applications of intracoronal bleaching.
• To summarize key aspects relevant to current clinical practice.

Main Methods:

• Review of historical and current literature on intracoronal bleaching agents and techniques.
• Analysis of research on the effects of bleaching agents on dental hard tissues.
• Examination of case reports concerning potential complications.

Main Results:

• Bleaching agents primarily utilize peroxide-based compounds in diverse formulations.
• The precise mechanism of bleaching remains under investigation.
• Concerns regarding invasive root resorption linked to intracoronal bleaching have prompted technique modifications.

Conclusions:

• Intracoronal bleaching is an established conservative treatment for internal tooth discoloration.
• Ongoing research focuses on refining techniques to enhance predictability and safety.
• Addressing risks such as root resorption is crucial for modern intracoronal bleaching protocols.
