Medical Emergencies · patient case question

What should come FIRST in the sequence of care for this patient?

Patient case: Adult presenting for periodontal therapy with no medical care in ten years

Patient: Male, 54 years old

Chief Complaint: “I just want my teeth cleaned. I have not been to any doctor in years.”

Background: No physician contact in approximately ten years. No known diagnoses, takes no medications, no allergies reported. Smokes half a pack daily.

Vital Signs: BP 158/96 mmHg on two readings · HR 88 bpm · RR 16 · T 98.4°F

Findings: Generalized heavy calculus, probing depths 5–7 mm interproximally, bleeding on probing at most sites, no acute swelling or pain.

  1. Perform full-mouth debridement under antibiotic prophylaxis
  2. Proceed with scaling and root planing after taking a full history and recording vital signs, and refer him for medical evaluation
  3. Tell him to return once he has established care with a physician
  4. Postpone all treatment until a physician has issued written clearance
Show answer and explanation

Correct answer: B. Proceed with scaling and root planing after taking a full history and recording vital signs, and refer him for medical evaluation

  • A. Antibiotic prophylaxis is determined by cardiac and immune indications, none of which are present. Undiagnosed hypertension is not an indication.
  • B. CORRECT. Two things happen at this visit: the risk assessment (history, vitals, ASA classification) and the periodontal therapy itself. Scaling and root planing is low-risk care that this patient needs, and it is not contraindicated by an undiagnosed elevated blood pressure at this level. The 158/96 reading and the ten-year gap generate a REFERRAL for medical evaluation — running in parallel with treatment, not blocking it.
  • C. Sending a patient away without care is the least defensible option. It abandons an active disease process and assumes he will return, which patients in this pattern frequently do not.
  • D. A blanket wait for written clearance is not required for non-surgical periodontal therapy in a patient with no diagnosed systemic disease and no symptoms. Clearance is a consultation about a SPECIFIC question, not a licence to treat, and demanding it here simply delays needed care.

Note: Blood-pressure thresholds worth carrying: below 160/100 proceed with routine care and refer for evaluation; 160–179/100–109 proceed with limited elective care, monitor, refer promptly; 180/110 or above defer elective treatment and arrange urgent medical assessment. Emergency care can proceed at any level with monitoring.
