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.
