Coronal seal in endodontics: a critical but forgotten element

Area of Science:

• Endodontics
• Restorative Dentistry
• Microbiology

Background:

• Root canal treatment success relies on asepsis and disinfection.
• The apical seal is traditionally emphasized, but the coronal seal's importance is debated.
• An integrated approach considering both seals is vital for endodontic outcomes.

Purpose of the Study:

• To review evidence on the importance of the coronal seal in endodontic treatment.
• To examine microbiologic, clinical, and materials science perspectives on coronal sealing.
• To highlight the necessity of an integrated approach for successful root canal therapy.

Main Methods:

• Comprehensive literature review.
• Analysis of microbiologic, clinical, and materials science data.
• Evaluation of the timing and materials for coronal restorations.

Main Results:

• Both effective root canal filling and timely coronal restoration are essential for long-term success.
• A high-quality coronal seal prevents bacterial microleakage and reinfection.
• Prompt placement of a permanent coronal restoration is critical.

Conclusions:

• The coronal seal plays a pivotal role in the longevity of endodontically treated teeth.
• Clinicians must prioritize immediate and high-quality coronal restoration after root canal procedures.
• An integrated strategy encompassing both apical and coronal sealing ensures optimal treatment outcomes.
