✅ Introduction
Pulpal infections in primary teeth are a common cause of dental pain and tooth loss in children. The 2024 American Academy of Pediatric Dentistry (AAPD) guidelines emphasize accurate diagnosis, conservative pulp therapy, and the use of bioactive materials such as MTA and Biodentine for improved long-term success (AAPD, 2024).

✅ Classification of Pulpal Conditions (AAPD 2024)
According to the AAPD 2024 guidelines, pulpal conditions are classified as:

▪️ Normal pulp – healthy pulp, no symptoms.
▪️ Reversible pulpitis – transient pain to stimuli, pulp can recover.
▪️ Irreversible pulpitis – spontaneous/prolonged pain, inflamed pulp beyond repair.
▪️ Pulp necrosis – non-vital pulp tissue.
▪️ Chronic periapical abscess – low-grade, draining sinus tract present.
▪️ Acute periapical abscess – severe pain, swelling, systemic symptoms possible.

📊 Symptoms of Pulpal Infection Processes

Pulpal Condition	Main Symptoms	Clinical Indicators
Reversible Pulpitis	Short, sharp pain to stimuli	No spontaneous pain; normal radiograph
Irreversible Pulpitis	Spontaneous or nocturnal pain	Deep caries; no haemostasis after coronal pulp removal
Pulp Necrosis	No response to stimuli	Periapical radiolucency; non-vital pulp
Chronic Periapical Abscess	Usually asymptomatic	Draining sinus tract; mild tenderness
Acute Periapical Abscess	Severe, throbbing pain with swelling	Fever, facial edema, lymphadenopathy

✅ Evidence-Based Protocols (AAPD, 2024–2025)

1. Diagnosis and Radiographic Evaluation
▪️ Record detailed history and perform percussion, palpation, and vitality tests.
▪️ Take periapical radiographs to evaluate pulpal and periapical status.
▪️ Classify condition using AAPD 2024 categories to guide treatment choice.

2. Management Protocols
➤ Reversible Pulpitis
▪️ Perform indirect pulp therapy or restoration.
▪️ Place calcium hydroxide or glass ionomer liner and restore with composite or stainless steel crown.
➤ Irreversible Pulpitis (vital pulp)
▪️ Perform pulpotomy: remove coronal pulp, control bleeding, and apply MTA or Biodentine.
▪️ Seal with resin-modified glass ionomer and restore with a stainless steel crown.
➤ Pulp Necrosis / Chronic Abscess
▪️ If tooth is restorable, perform pulpectomy using resorbable filling materials like Vitapex or Metapex.
▪️ If non-restorable, perform extraction and maintain space when needed.
➤ Acute Abscess with Systemic Symptoms
▪️ Drain via tooth or incision.
▪️ Prescribe amoxicillin (20–40 mg/kg/day divided every 8h) or azithromycin/clindamycin if allergic.
▪️ Combine with definitive dental treatment and follow-up in 3–7 days.

Facial cellulitis and angioedema are two potentially life-threatening conditions frequently encountered in dental emergencies. Although both present with facial swelling, they differ significantly in etiology, clinical presentation, and treatment approach.

3. Follow-Up
▪️ Evaluate at 3, 6, and 12 months clinically and radiographically.
▪️ Success criteria: absence of pain, swelling, mobility, or radiolucency.

✍️ Conclusion
Management of pulpal infections in primary teeth must follow AAPD evidence-based protocols, prioritizing pulp vitality and infection control. The use of bioactive materials, accurate diagnosis, and periodic follow-up are essential to maintain oral health and prevent premature tooth loss in pediatric patients.
