Selective Nonsurgical Endodontic Retreatment: Relevant Aspects for Clinical Application-A Scoping Review

Area of Science:

• Endodontics
• Dental Surgery
• Conservative Dentistry

Background:

• Persistent or secondary endodontic infections require retreatment.
• Conventional retreatment can be invasive and costly.
• Evaluating conservative alternatives is crucial for patient outcomes.

Purpose of the Study:

• To explore clinical applications and outcomes of selective nonsurgical endodontic retreatment.
• To assess the efficacy and benefits of a conservative retreatment approach.
• To review evidence on clinical success, tooth survival, and cost-effectiveness.

Main Methods:

• Scoping review methodology adhering to PRISMA-ScR guidelines.
• Systematic literature search across six databases.
• Inclusion of seven eligible studies assessing various outcomes.

Main Results:

• Selective retreatment demonstrates comparable clinical results to conventional retreatment.
• Benefits include enhanced preservation of tooth structure and improved fracture resistance.
• This approach appears more cost-effective by minimizing further interventions.

Conclusions:

• Selective nonsurgical endodontic retreatment is a viable conservative option.
• Cone-beam computed tomography supports diagnosis and case selection for this approach.
• Further high-quality clinical trials are necessary to validate findings due to low-to-moderate evidence quality.
