Overview
Primary active dental caries extending into the pulp indicates irreversible pulpitis, necessitating urgent endodontic intervention to prevent complications such as abscess formation and systemic infection.Diagnosis
Clinical Signs: Severe toothache, sensitivity to thermal changes, swelling, and sometimes fever 1.
Radiographic Evaluation: Periapical radiographs to assess extent of caries and involvement of the pulp and periapical tissues 1.
Pulp Sensitivity Tests: Not typically reliable in cases of irreversible pulpitis; often inconclusive 1.Management
Immediate Pain Management: Analgesics such as NSAIDs (e.g., ibuprofen) for pain relief 1.
Antimicrobial Therapy: Consider systemic antibiotics if there is evidence of systemic involvement or severe infection 1.
Palliative Care During Pandemics: Use of non-aerosol-generating interventions and pharmacologic therapy when aerosol-generating procedures are contraindicated 2.
Inhalation Sedation: For pediatric patients, nitrous oxide (N2O)-oxygen mixtures can be effective for sedation, ensuring oxygen saturation remains above 90% 4.
Root Canal Treatment: Definitive treatment involves initiating root canal therapy to remove necrotic pulp tissue and irrigate canals 1.Special Populations
Pediatrics: Utilize inhalation sedation techniques like N2O-oxygen mixtures for effective and safe management 4.
Comorbidities: Consider systemic antibiotic use cautiously in patients with compromised immune systems or systemic infections 1.Key Recommendations
Initiate Root Canal Therapy Promptly to address irreversible pulpitis and prevent complications (Evidence: Strong 1).
Use Non-Aerosol-Generating Interventions during pandemics for palliative care in emergency cases (Evidence: Moderate 2).
Monitor Oxygen Saturation in pediatric patients undergoing sedation with N2O-oxygen mixtures (Evidence: Moderate 4).
Consider Systemic Antibiotics in cases with significant periapical involvement or systemic signs of infection (Evidence: Moderate 1).References
