Study Notes

Trans-illumination Test

Used to assess tooth structure integrity.
Illuminates tooth with powerful light to detect internal cracks, fractures, and pulp chamber size.

Staining Test

Evaluates tooth structure integrity and presence of cracks.
Involves applying a dye to the tooth surface, observing dye penetration into internal cracks.

Bite/Cusp Loading Tests

Determines the origin of pain by applying pressure to specific cusps or areas of the tooth.
Patient instructed to bite down on a cotton roll or instrument to elicit pain response.

Selective Anesthesia Test

Differentiates between odontogenic pain (originating from teeth) and non-odontogenic pain.
Involves administering local anesthetic to specific nerves and observing pain reduction or elimination.

Gutta-Percha Tracing with Radiograph

Used to visualize the extent of root canal filling with gutta-percha during endodontic procedures.

Anginal Pain

Anginal pain in the lower left jaw is a symptom of myocardial ischemia (reduced blood flow to the heart muscle).
It is typically described as a crushing or squeezing pain.

Myofacial Pain

Differentiated from odontogenic pain by its tenderness on palpation of the muscles of mastication, not the tooth itself.

Neurovascular Toothache vs Odontogenic Pain

Neurovascular toothache is caused by irritation of the nerves and blood vessels in the tooth, distinct from odontogenic pain, which originates from the tooth tissues.

Neuropathic Toothache Characteristics

Characterized by a burning, tingling, or shooting sensation in the tooth.

Pulpitis Pain

Becomes sharp and throbbing when inflammation reaches the pulp chamber.

Periapical Pain

Characterized by a persistent, throbbing pain that intensifies at night or when the tooth is exposed to hot or cold temperatures.

Sickle Cell Anemia Complication

Common painful complication is osteonecrosis (bone death), which can affect the jawbone and lead to toothache.

C-fiber Mediated Pulpal Pain

Slow, aching, and throbbing pain associated with inflammation in the dental pulp.

Neuropathic Toothache Diagnostic Challenge

Identifying the underlying cause, as it may be difficult to differentiate from other types of toothache.

Psychogenic Toothache Distinction

No identifiable dental or medical reason for the pain, often linked to psychological factors.

Pulp Status Assessment

When other tests are inconclusive, an electrical pulp test assesses the vitality of the pulp.

Necrotic Pulp Tissue

May still contain viable cells despite being considered non-vital.

Periradicular Lesion Radiographic Mimic

A periapical cyst can resemble a periradicular lesion radiographically.

Pulpitis Pain Category

Reversible pulpitis is characterized by aching and throbbing pain radiating from the maxilla to the mandible or vice versa.

Tooth Sensitivity and Gingiva Tenderness

Likely diagnosis is periodontitis involving the gums and supporting tissues.

Chronic Periapical Abscess vs Chronic Apical Periodontitis

Chronic periapical abscess involves a localized collection of pus, while chronic apical periodontitis typically involves inflammation at the apex of the tooth without pus formation.

Primary Odontogenic Pain Sources

Dental pulp, periodontal tissues, and periapical tissues.

Non-Odontogenic Toothache Warning Signs

Facial swelling, fever, and lymphadenopathy (swollen lymph nodes).

Non-Responsive Symptomless Tooth

Likely diagnosis is a non-vital tooth with a history of trauma or previous endodontic treatment.

Magnifying Loupes and Microscopes in Endodontics

Provide enhanced visualization during root canal procedures, improving precision and accuracy.
