    Study Notes

    Pulpal Pathology and Inflammation

    • Damage to dental layers can arise from caries, cracks, fractures, tooth wear, and restorative or periodontal procedures.
    • Bacterial invasion through dentine leads to toxin release, prompting the pulp to produce tertiary dentine, acting as a protective barrier.
    • Once bacteria penetrate inner dentine layers, significant pulpal inflammation occurs, potentially resulting in irreversible pulpitis.
    • Increased irritation, such as from restorative procedures, can exacerbate pre-existing pulpal inflammation, potentially resulting in necrosis.

    Signs and Symptoms of Pulpal Disease

    • Clinical signs include tooth discoloration and periapical radiolucency, which often resolves within three months post-injury.
    • Negative responses to pulp testing may occur initially but typically resolve within a year.
    • Pain triggers include bite pressure and temperature changes, indicating conditions like acute apical periodontitis or apical abscess.

    External Inflammatory Resorption

    • Injury to tooth structure can expose cementum, leading to pulpal necrosis and bacterial infection.
    • Bacterial toxins cause an inflammatory response, leading to external resorption by osteoclasts; clinical findings vary from symptomatic to asymptomatic.
    • Radiographic findings may show loss of tooth structure and adjacent bone radiolucencies, often requiring root canal treatment and possibly microsurgery.

    External Replacement Resorption

    • Severe intrusion/avulsion injuries can damage the periodontal ligament (PDL), leading to osteoclast-mediated resorption of the root, replaced by bone from the alveolar bone.
    • Pain provocation factors typically include biting or temperature changes.

    Duration of Pain and Medical History

    • Pain lasting seconds suggests dentine hypersensitivity; moments of pain lasting minutes indicate irreversible pulpitis.
    • An updated medical history is crucial; specific patient conditions (e.g., those on bisphosphonates or with cardiovascular issues) necessitate treatment modifications.

    Internal Resorption Mechanisms

    • Internal root resorption is initiated by damage to the odontoblast/predentine layers, often linked to bacterial stimulation.
    • Symptoms can vary, with clinical and radiographic findings indicating pulpal and periapical disease.

    Management Strategies

    • Endodontic treatment with an inter-appointment calcium hydroxide dressing is recommended for internal resorption cases.
    • Cone beam computed tomography (CBCT) is advised for evaluating the extensiveness of resorptive defects.

    External Cervical Resorption (ECR)

    • ECR results from cementum damage that exposes dentine, allowing osteoclasts to resorb the underlying tissue.
    • Diagnosis often occurs through probing or radiographic investigation, with treatment options varying based on the defect's location and nature.

    History Taking and Diagnosis

    • Diagnosis of endodontic disease requires thorough history-taking, complemented by extraoral and intraoral examinations.
    • Proper evaluation is essential for accurate identification of underlying causes related to a patient's signs and symptoms.

    Anticoagulants and Risk Assessment

    • Anticoagulant (e.g. warfarin) and antiplatelet drugs increase bleeding risk; INR testing is possible for warfarin but not for newer anticoagulants.
    • Prior to procedures, a thorough risk assessment is crucial, especially for patients at high bleeding risk, prompting possible consultation with their medical practitioner.
    • Consultations may lead to alterations in the patient's medication schedule.

    Patient Allergies and Reactions

    • Allergies commonly include antibiotics and latex; however, there's a noted increase in anaphylaxis incidents due to chlorhexidine use.
    • Dentists must be prepared to recognize and manage anaphylactic shock.

    Special Considerations for Specific Patient Groups

    • Patients on long-term steroids or those with diabetes can have poorer outcomes post-root canal but are still eligible for treatment.
    • Appointment scheduling for diabetic patients should align with their meals to manage blood glucose levels.
    • Pregnant patients may choose to postpone non-essential radiographs until after the first trimester yet may still require them for acute pain assessments; radiation precautions should always be observed.

    Extraoral Examination

    • Assess for swelling and asymmetry; palpate lymph nodes for infection signs.
    • Firm, tender lymph nodes with fever indicate potential infection.
    • Evaluate the temporalis and masseter muscles for hypertrophy and tenderness.

    Pain Provocation and Symptoms

    • Identify triggers affecting symptoms; biting or temperature changes often initiate pain.
    • Pain on biting may indicate apical periodontitis or abscess; prolonged responses to temperature suggest pulp inflammation.
    • Non-steroidal anti-inflammatory drugs (NSAIDs) relief hints at an inflammatory process.

    Pain Duration and Medical History Relevance

    • Brief pain indicates dentine hypersensitivity; lasting pain post-stimulation suggests irreversible pulpitis.
    • Update medical history questionnaires at each appointment; treatment modifications may be necessary for patients on specific medications.
    • Conditions like cardiovascular or renal issues may alter drug metabolism, necessitating dosage adjustments.

    Equipment and Treatment Considerations

    • Certain medical devices (e.g., pacemakers) can interfere with dental equipment; consult a cardiologist if needed.
    • Assess the patient's smile line as this affects treatment decisions, particularly regarding facial aesthetics.

    Intraoral Examination

    • Conduct a thorough soft tissue examination; document and monitor any lesions.
    • Examine intraoral swellings visually and through palpation; sinus tracts may indicate drainage from chronic infections.
    • Assess overall dental condition, noting defective fillings and caries prior to detailed evaluation of specific teeth.

    Diagnostic Procedures

    • Conduct tests for tenderness, vitality, occlusion, and periodontal status; consider the contralateral tooth for comparative understandings.
    • Utilize special tests if uncertainties about diagnosis persist; definitive diagnosis may emerge post-treatment.

    Patient History and Presenting Symptoms

    • Elicit patient-reported concerns relevant to their visit; use open and closed questioning techniques.
    • Assess pain location, intensity, onset, and duration to gain specific insights into the problem.

    External Cervical Resorption Management

    • Recognize that resorption results from cementum damage exposing dentine; the pulp is unaffected until advanced stages.
    • Diagnosis includes probing and scaling for asymptomatic lesions; treatment options vary based on resorption location and tooth condition, ranging from repair to extraction.

    Conclusion

    • Diagnosis of endodontic disease requires comprehensive history and examinations. Ensure proper protocols are followed for clinical tests to determine causes of patient signs and symptoms effectively.
