TREATMENT OF CHRONIC APICAL PERIODONTITIS: IN A SINGLE OR MULTIPLE VISITS? (REVIEW)

Area of Science:

• Endodontics
• Dental Treatments

Background:

• Chronic apical periodontitis presents a significant endodontic challenge.
• Treatment effectiveness often depends on the chosen protocol, single versus multiple visits.

Purpose of the Study:

• To systematically review and compare the effectiveness of single-visit versus multiple-visit treatments for chronic apical periodontitis.
• To identify optimal procedural elements and materials for successful endodontic outcomes.

Main Methods:

• A systematic literature review was performed on databases including PubMed, Google Scholar, ResearchGate, and ScienceDirect.
• Articles published between 2011 and 2021 focusing on treatment effectiveness were selected and analyzed.
• Nine articles were chosen for detailed review from an initial selection of 21.

Main Results:

• Single-visit treatment for chronic apical periodontitis can be effective when executed with proper shaping, disinfection, and hermetic obturation.
• Bioceramic sealers demonstrated the highest success rates among tested materials.
• Advanced techniques such as photodynamic therapy and ultrasonic activated irrigation yielded outstanding results.

Conclusions:

• Single-visit endodontic therapy is a viable and effective option for chronic apical periodontitis.
• The choice of irrigants (e.g., sodium hypochlorite, EDTA) and sealers (e.g., bioceramics) significantly impacts treatment success.
• Emerging technologies like photodynamic therapy and ultrasonic irrigation offer superior disinfection and treatment outcomes.
