Mastering Endodontic Diagnosis - iNBDE, NDEB AFK, NEET, ADC

Apply a controlled diagnostic test to reproduce patient symptoms and identify the responsible tooth, exploring pulp tests (cold, heat, EBD), percussion, bite tests, probing depths, sinus tracking, and selective anesthesia.

No single diagnostic test suffices; all tests have limitations. Combine objective findings, patient history, chief complaint, and the tests, using controls to reach a reliable conclusion.

Explore pulp vitality tests, including cold and heat tests, electric pulp test, and laser doppler flow metric—the latter the most reliable yet impractical option emphasized in exams.

Evaluate cold tests for pulpal vitality using dry ice, ice, and spray, noting temperatures. Ice sticks are most common; dry ice offers the lowest temperature but requires special equipment.

Use heat tests only when patients report heat-related pain, to avoid harming inflamed pulp. Apply controlled heat and note possible false positives in necrotic pulp; heat mainly excites a-delta fibers.

Learn how electric pulp tests assess pulp vitality, interpreting no response as non-vital and noting limitations like false positives and crown material interference.

Master test cavity preparation by performing a small class i cavity without local anesthesia to assess vitality when necrosis is uncertain, using patient response and radiologic tests to guide restoration.

Learn how to determine pulp vitality with laser Doppler flowmetry and pulse oximetry, comparing blood flow detection to oxyhemoglobin measurement for endodontic diagnosis.

Learn about periradicular tests in endodontics, including progression, palpation, bite, and percussion tests, and mobility assessment used in diagnosing acute abscesses.

Percussion tests assess periodontal ligament inflammation, not vitality, by comparing tenderness between teeth; use the blunt end of a mouth mirror to gently tap the tooth.

Identify soft tissue swelling and bony expansion near the apex using palpation tests in endodontics, where a positive response indicates active inflammatory pain and aids diagnosis.

Assess tooth mobility in endodontics to gauge periodontal support, distinguishing normal and grade 1–3 mobility, while considering trauma, occlusion, periodontal disease, root fracture, orthodontic treatment, and abscess as possible causes.

Understand the bite test in endodontics: pain on biting indicates tenderness to percussion, while pain on release suggests a cracked or fractured tooth, a common board exam topic.

Explore how periodontal assessment complements endodontic tests by evaluating probing depths to detect vertical root fractures and differentiate diagnoses, emphasizing careful probing as a critical diagnostic step.

Learn about special endodontic tests such as sinus tract tracing, selective anesthesia with blocks, class I cavity test, and crack detection using methylene blue dye.

Explore four types of antibody tests and the diagnosis as the crux of testing, emphasizing critical information for competitive exam preparation.

Learn to distinguish pulpal from periapical diagnosis, articulating both independently, and determine whether the pulp is inflamed and reversible or irreversible while assessing the periapical status.

Explore pulpal diagnoses from healthy baseline to reversible and irreversible pulpitis, asymptomatic and symptomatic, necrosis, and previously treated cases, using test responses.

Explore differential pulpal diagnosis in endodontics, contrasting normal pulp, reversible and irreversible pulpitis (early and late stages), asymptomatic cases, and pulp necrosis, with test findings and treatment options.

Explore types of periapical and periradicular diagnoses, including symptomatic versus asymptomatic lesions, emergency abscess needing incision and drainage, and radiographic findings such as condensing osteitis and pulp calcifications.

Explore differential periapical diagnoses in endodontics by comparing normal, symptomatic, and asymptomatic pulp status and evaluating swelling, bite response, and radiographic pdl widening for treatment decisions.

Explore differential periapical diagnosis in endodontics, from acute abscess and necrosis to chronic abscess, granuloma, and cyst, and learn evidence-based treatment decisions with vitality considerations.
