Study Notes
Emergency Conditions in Endodontics
- Endodontic emergencies involve pain and/or swelling due to infection or inflammation of pulpal and/or periapical tissues, requiring immediate diagnosis and treatment.
- Real emergencies involve situations where waiting is impossible, pain is severe, and analgesics are ineffective, impacting sleep, eating, and daily activities.
- Common conditions include traumatic injuries, and inflammatory conditions of the pulp and periapical tissues (e.g., dental decay, pulp infection, root canal infection, periapical tissue infection).
Types of Endodontic Emergencies
- Teeth with irreversible pulpitis with normal periapex: Irreversible pulpitis with a normal periapical area.
- Teeth with irreversible pulpitis and acute apical periodontitis: Irreversible pulpitis accompanied by an acute apical inflammatory response.
- Teeth with necrotic pulp without swelling, with acute apical periodontitis: Necrotic pulp without swelling, but with an active acute apical process.
- Teeth with necrotic pulp with fluctuant swelling with drainage: Necrotic pulp with swelling that fluctuates and drains.
- Teeth with necrotic pulp with fluctuant swelling without drainage: Necrotic pulp with swelling that fluctuates but does not drain.
- Teeth with necrotic pulp with diffuse facial swelling with drainage through the canal: Necrotic pulp with spreading facial swelling that drains via a canal opening.
- Teeth with necrotic pulp without drainage and diffuse facial swelling: Necrotic pulp with diffuse, non-draining facial swelling
- Painful conditions before treatment, involving teeth with vital pulp, include reversible pulpitis and irreversible pulpitis.
Reversible Pulpitis
- Reversible pulpitis is not a real emergency.
- It causes pain to cold, hot, sweet, and sour stimuli
- Causes: Caries, exposed dentin, recent dental treatment, damaged restorations, occlusal trauma.
- Treatment: Removal of the irritant, application of desensitizing agents, and restoration.
Irreversible Pulpitis
- Irreversible pulpitis requires urgent treatment.
- Pain is severe, spontaneous, and may be present at night.
- Pain is triggered by thermal changes. The pain persists even after the stimulus is removed.
- Referred pain may be present.
- Treatment includes root canal treatment or extraction; in some cases, aggressive cleaning of the affected tooth area to avoid recontamination of the root canal system is required. Removal of pulp and application of calcium hydroxide (Ca(OH)2).
Acute Apical Periodontitis
- Cause: Infected pulp, tissue damage (due to chemomechanical preparation) or occlusal trauma, food impaction, high restoration.
- Characteristics: Sensitivity to percussion (+), pain during biting and chewing, mobility of the tooth, possibly tooth vitality or devitality, and associated symptomatic irreversible pulpitis.
- Treatment: Focuses on the underlying cause, using NSAID analgesics if required, to relieve symptoms.
Importance of Maintaining Apical Constriction
- Proper management crucial to prevent infection or further tooth damage.
- Maintaining this constriction is essential to prevent the spread of infection or further tooth problems.
Emergencies in Teeth with Necrotic Pulp:
- Teeth with necrotic pulp without swelling: Chemomechanical preparation; calcium hydroxide medication.
- Teeth with necrotic pulp with swelling (acute apical abscess): Localized swelling -> open access cavity, drain through the canal, clean, seal. Diffuse swelling -> antibiotics; open canal, clean, seal, and place calcium hydroxide.
Psychological Approach
- Correct diagnosis is a critical aspect of the process, involving identifying the patient's complaint, reviewing their medical history, and applying diagnostic protocols.
Other Emergency Types
- Emergencies in a tooth that has not been treated before.
- Emergencies that occur after endodontic treatment has started (acute exacerbation/flare-up).
- Emergencies occurring later in a tooth whose endodontic treatment has been completed.
Clinical Conditions Considered as Endodontic Emergencies
- A range of clinical situations is considered endodontic emergencies. These situations require a thorough, accurate assessment, and prompt treatment to avoid worsening the condition.
Cracked Tooth Syndrome (CTS)
- CTS involves an elongated fracture line in the tooth structure, possibly extending to the pulp or periodontal ligament.
- Depth and progression are usually unknown.
- Characteristics: Pain during chewing that can be sharp, short term, or spontaneous and long lasting.
Bite Test
- Method used to detect cracks.
- Procedures can involve wood sticks, cotton rolls, or other devices, often requiring the patient's cooperation.
- Different tools and techniques are used based on the degree of sensitivity required and the anatomy of the impacted tooth.
Diagnosis of Endodontic Emergencies
- Accurate diagnosis is vital for appropriate treatment.
Treatment
- Specific approaches depend on the type of emergency involved. Usually involves immediate pain relief and an identification of the root causes to ensure treatment effectiveness.
Prognosis
- Determined based on the extension of the fracture line, the presence of swelling in the affected tooth, location of the fracture on the tooth (i.e., coronal versus apical).
Flare-Up Treatment
- Assessment focused on pulp condition and swelling present. Immediate treatment addresses pain and possible infection.
- Specific procedures based on if the pulp is vital or necrotic.
Etiology of Acute Flare-ups
- Inadequately cleaned root canal systems.
- Overinstrumentation of the root canals
- Debris pushed into the periapical region.
- Overfilling of the root canal.
- Presence of a periapical lesion.
- Re-treatment cases.
- Factors relating to the patient's immune response.
Microbiology and Immunology of Acute Exacerbations
- A range of factors can contribute to acute flare-ups, including bacterial species within the root canals, variations in the host immune response and inflammatory mediators produced within the root canals.
Secondary Radicular Infection
- This is a secondary infection that occurs after a root canal treatment, due to various factors, including the presence of microorganisms, which may lead to flare-ups.
