    Study Notes

    Endodontic Diagnosis

    • Endodontic diagnosis involves separate pulpal and periapical diagnoses.
    • Pulpal diagnosis assesses the health of the pulp. Periapical diagnosis assesses the area surrounding the tooth's root apex.

    Pulpal Diagnosis

    • Responsive to cold? If yes, continue. If no, suspect pulp necrosis.
    • Pain? If yes, suspect pulpal inflammation. Consider if the pain is lingering or sharp.
    • Inflammation present? (Caries into pulp) If yes, determine if pain is lingering (>30 seconds).
    • Was RCT previously completed? If yes, determine if previously initiated.
    • How do control teeth respond? (+) or (-).
    • Normal pulp: Asymptomatic, responsive to thermal stimuli.
    • Reversible pulpitis: Symptomatic, responsive to stimuli, short-sharp pain subsiding.
    • Symptomatic irreversible pulpitis: Spontaneous, lingering or referred pain.
    • Asymptomatic irreversible pulpitis: Irreversible damage to pulp, no pain.

    Apical Diagnosis

    • Percussion and palpation test: Pain indicates periapical inflammation. No pain indicates no significant periapical lesion.
    • Sinus tract? If yes, determine presence of radiographic changes.
    • Normal apical tissues: Asymptomatic apices, normal anatomy.
    • Symptomatic apical periodontitis: Inflammation around apex, possibly responding to pulp testing, possible referral to a referred, lingering pain.
    • Asymptomatic apical periodontitis: Inflammation, negative response to pulp testing, asymptomatic apices.
    • Acute apical abscess: Swelling, pain on biting, palpation, pus formation, acute.
