✅ Anesthetic Agents Commonly Used in Pediatric Dentistry

Lidocaine (2% with epinephrine 1:100,000)
Lidocaine remains the gold standard local anesthetic in pediatric dentistry due to its rapid onset, adequate depth of anesthesia, and well-documented safety profile.

Articaine (4% with epinephrine 1:100,000)
Articaine provides enhanced bone penetration, making it effective for infiltration anesthesia in mandibular primary molars. However, its use in young children must be carefully dosed.

Mepivacaine (3% plain)
Indicated when vasoconstrictors are contraindicated, mepivacaine offers moderate duration anesthesia but reduced hemostasis.

✅ Anesthetic Techniques for Pulp Therapy in Children

Infiltration Anesthesia
Preferred for maxillary teeth and increasingly effective in mandibular primary molars due to thinner cortical bone.

Inferior Alveolar Nerve Block
Indicated for extensive mandibular pulp therapy but associated with higher failure rates and postoperative soft tissue trauma.

Supplemental Techniques
▪️ Intraligamentary anesthesia
▪️ Intrapulpal anesthesia (used only when other techniques fail)
These approaches enhance pain control during inflamed pulpal procedures.

Understanding the dosage limits, pharmacology, and safety profiles of common local anesthetics used in children allows clinicians to minimize adverse events and achieve optimal operative conditions.

✅ Pain Modulation Strategies Beyond Anesthesia
Adjunctive methods such as behavior guidance techniques, topical anesthetics, slow injection rates, and age-appropriate communication significantly improve perceived pain control. The combination of pharmacological and psychological strategies is essential for optimal pediatric pain management.

💬 Discussion
Despite advances in anesthetic pharmacology, pain during pediatric pulp therapy remains a clinical challenge, particularly in teeth with irreversible pulp inflammation. Studies demonstrate that articaine infiltration may outperform traditional nerve blocks in primary mandibular molars, reducing discomfort and soft tissue injury. However, technique sensitivity, dosage accuracy, and patient behavior remain critical variables influencing anesthetic success.

✅ 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.

✅ 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.
