[Root canal post for build-up restorations: necessary or redundant?]

Area of Science:

• Endodontics
• Restorative Dentistry
• Dental Materials Science

Context:

• Root canal posts historically provided retention for build-up restorations in endodontically treated teeth.
• Recent advancements in adhesive dentistry and a lack of robust clinical evidence have led to a decline in post usage.
• Current European Society of Endodontology guidelines advocate for selective post placement.

Purpose:

• To evaluate the evolving role and indications for root canal posts in restorative dentistry.
• To highlight the importance of preserving tooth structure and minimizing invasive preparation procedures.
• To inform clinical decision-making regarding the necessity of posts for functionally reconstructing endodontically treated teeth.

Summary:

• Root canal posts are used to enhance retention for restorations on endodontically treated teeth.
• Their use is decreasing due to improved adhesive techniques and limited clinical data supporting their necessity.
• Posts are now primarily recommended for anterior teeth and premolars when no coronal dentin remains, with a strong caution against unnecessary tooth preparation.

Impact:

• Reduced reliance on root canal posts may lead to more conservative and tooth-preserving treatment strategies.
• Emphasizes the critical importance of minimizing iatrogenic damage during post placement procedures.
• Promotes evidence-based decision-making in endodontic restorative treatment planning.
