✅ What Is One-Visit Pulpectomy?
One-visit pulpectomy involves complete removal of necrotic or inflamed pulp tissue, canal disinfection, obturation, and coronal sealing in a single appointment. Advances in instrumentation, irrigation protocols, and obturating materials have made this approach increasingly feasible.
The primary objective is to eliminate infection while minimizing patient discomfort and treatment time.

Triple Antibiotic Paste (TAP) has gained significant attention in pediatric endodontics, particularly in the management of necrotic primary teeth and immature permanent teeth.✅ Indications and Case Selection
Appropriate case selection is critical. One-visit pulpectomy is generally indicated when:
▪️ The child is cooperative or behavior management is limited
▪️ There is no acute swelling or systemic involvement
▪️ Canal anatomy is manageable
▪️ Adequate isolation can be achieved
Teeth with extensive periapical pathology or uncontrolled infection may still benefit from multi-visit treatment.

Understanding the clinical indications, long-term outcomes, advantages, and limitations of each technique is essential for optimizing patient care and maintaining primary teeth until exfoliation.✅ Safety Considerations
Current evidence suggests that one-visit pulpectomy is safe when proper disinfection and obturation protocols are followed. The use of resorbable filling materials compatible with physiological root resorption is essential.
Potential concerns include:
▪️ Incomplete microbial elimination
▪️ Risk of postoperative flare-ups
However, studies show no significant increase in postoperative complications compared to multi-visit approaches.

This 2025 update provides a concise, evidence-based overview of pulpal infection management in primary teeth, following the latest AAPD 2024 classification and clinical protocols.✅ Effectiveness and Clinical Outcomes
Clinical success is evaluated based on:
▪️ Absence of pain or swelling
▪️ Radiographic resolution or stability of periapical lesions
▪️ Normal exfoliation timing
Success rates of one-visit pulpectomy are comparable to multi-visit protocols, particularly when modern materials such as calcium hydroxide–iodoform pastes are used.

The debate between one-visit and multi-visit pulpectomy mirrors broader discussions in endodontics. While multi-visit procedures allow for intracanal medicaments, evidence increasingly supports that effective mechanical and chemical disinfection in a single visit can achieve similar outcomes. In pediatric dentistry, reduced chair time and improved patient cooperation are significant advantages.
✍️ Conclusion
One-visit pulpectomy in primary teeth is a safe and effective treatment option when appropriate case selection and strict clinical protocols are followed. Its advantages in pediatric behavior management and treatment efficiency make it an attractive alternative to traditional multi-visit approaches.
