CIT Pharmacology & Medications in Implantology 3

Question 1

A patient develops urticaria (hives) and facial swelling shortly after receiving amoxicillin prophylaxis before implant surgery. This presentation is most consistent with:

Accepted Answer

An IgE-mediated (Type I) allergic reaction requiring immediate intervention

Answer

A normal vasovagal response to dental anxiety

Answer

A delayed hypersensitivity reaction to chlorhexidine

Answer

Lidocaine toxicity from the local anesthetic injection

Question 2

Prolonged antibiotic use after implant surgery may necessitate prescribing a supplemental antifungal agent. Which antifungal is most commonly used for oral candidiasis in this scenario?

Accepted Answer

Nystatin oral suspension

Answer

Fluconazole 150 mg single dose

Answer

Voriconazole 200 mg daily

Answer

Terbinafine 250 mg daily

Question 3

What is the primary advantage of using acetaminophen (paracetamol) over NSAIDs for post-implant pain management in patients with peptic ulcer disease?

Accepted Answer

Acetaminophen does not inhibit COX enzymes and therefore does not irritate the gastric mucosa

Answer

Acetaminophen has superior anti-inflammatory activity

Answer

Acetaminophen provides faster onset of analgesia

Answer

Acetaminophen promotes platelet aggregation to aid wound healing

Question 4

A patient on long-term corticosteroid therapy is being evaluated for implant surgery. The primary concern regarding their steroid use is:

Accepted Answer

Adrenal suppression and potential for adrenal crisis under surgical stress

Answer

Increased risk of implant rejection due to autoimmune activation

Answer

Enhanced bone density that may complicate osteotomy preparation

Answer

Reduced local anesthetic requirements due to increased pain tolerance

Question 5

Which medication class is known to potentially impair osseointegration by interfering with bone remodeling at the cellular level?

Accepted Answer

Long-term systemic corticosteroids

Answer

Proton pump inhibitors (PPIs)

Answer

Beta-blockers

Answer

H2 receptor antagonists

Question 6

When documenting a patient's medication history before implant surgery, which class of supplement is most important to identify due to its antiplatelet effects?

Accepted Answer

Answer

Vitamin C and zinc supplements

Answer

Calcium and vitamin D supplements

Answer

Probiotics and digestive enzymes

Question 7

What is the minimum inhibitory concentration (MIC) relevant to antibiotic selection for peri-implant infections?

Accepted Answer

The lowest concentration of an antibiotic that inhibits visible bacterial growth in vitro
