Management of endodontic
emergencies
• Pain
• Swelling ELIMINATE!!!
• Inflammation

Etiologies
• The inflammatory responses are mediated by
inflammatory mediators:
histamine, prostaglandin, szerotonin,
substance P (P-anyag), kalcitonin-gén-
related peptide (CGRP), neurokinin A,
bradykinin, kallidin, nitrogénmonoxid
• Tissue pressure
• Pulp pathosis
• Periapical pathosis

Diagnosis
• Medical history
• Dental history
• Differential diagnosis
• Pain perception
• Extraoral examination
• Intraoral examination
periodontal examination
pulp vitality test
• Radiographic examination
• Heart diseases
• Pacemaker
• Bacteriaemia
• Diabetes
• Motivation
• Mental status
The pain
• onset
• localisation
• intensity
• nature
• duration
• evoking (spontaneity, stimulus)
• radiation
Previous dental treatment

Anesthesia • Inferior alveolar nerve block
• Infiltration or block injection
• Intrapulpal
• Periodontal ligament
• Intraosseous
Swelling
• Pressure increases
• Exudate→The concentration of solution decreases
• pH value decreases

The classification of endodontic
emergencies
• Pretreatment emergency: emergency prior to
endodontic therapy (inflammatory changes in the pulp, periap.tiss.→ root canal treatment)
• Interappointment emergency: emergency during
root canal therapy (the reaction is related to root canal treatment)
• Postobturation emergency: problem following
obturation requires emergency treament (The symptoms may be due to obturation)
