of lower molar; bad taste in mouth
Objective: Signs
No fever, purulent exudates or other signs of systemic infection; visible open wound without clot
Assessment:
Differential Diagnosis - abscess, trauma, osteomyelitis (systemic signs)
Plan:
Antibiotics are rarely indicated.
- Local anesthesia
- Irrigation of extraction site with warm saline in syringe
- Cut approximately 1 1⁄2- 2 inch strip of iodoform gauze and apply 1 to 2 drops of (IRM liquid) eugenol.
Place this eugenol/gauze gently into affected socket - Change medicated gauze daily until symptoms are gone (usually 3 to 5 days)
- May also administer a NSAID for pain

- DISLOCATION OF THE TEMPOROMANDIBULAR JOINT(S)
COL Glenn Reside, DC, USA
Dislocation of the Temporomandibular Joint (TMJ) occurs frequently, usually caused by mandibular hypermo-
bility but can also be caused by trauma. The mandibular condyle translocates anteriorly in front of the articular
eminence and becomes locked in that position. Muscle spasm may then prevent the patient from closing
the jaw into normal occlusion. Dislocation may be unilateral or bilateral and may occur spontaneously after
opening the mouth widely while yawning, eating, or during a dental procedure. Dislocation of the TMJ is usually
painful, is not self-reducing, and usually requires professional management. Subluxation is a displacement of
the condyle that is self-reducing and requires no medical management. Dislocations should be reduced as
soon as possible.
Subjective: Symptoms
Pain in the preauricular area, accompanied by drooling and difficulty talking
Objective: Signs
Tender, bony prominence in preauricular area(s); malaligned dental bite; mouth locked in an open position
Assessment:
Differential Diagnosis - fractured mandible, tumor
Plan:
Treatment
Primary: Manually reduce the dislocated TMJ as soon as possible by moving the dislocated mandibular condyle
inferiorly and posteriorly from in front of the articular eminence and then superiorly into the glenoid fossa.
- Get behind the patient. If the patient is sitting in a chair, their head should be at the level of your waist. If
the patient is lying down on their back on the ground, you should sit on the ground at the patient’s head
and cradle their head in your lap. - Wrap your thumbs in gauze or a small towel (to avoid being bitten) and put them inside the patient’s mouth
behind the last molar on each side of the lower jaw. All four ngers of each hand should be placed along
the inferior border of the mandible with the forengers near the chin and the little ngers near the angles
of the mandible. Stabilize the patient’s head against the back of the chair or your torso if the patient is
sitting or in your lap if the patient is supine. - Apply rm, continuously increasing pressure downward (inferiorly) and backwards (posteriorly) on the
