Which hand hygiene method is recommended before patient contact in dental settings?
Alcohol-based hand rub
Wearing gloves only
Washing hands with cold water
Waterless surgical scrub
Alcohol-based hand rub is recommended before patient contact as it effectively removes pathogens and dries quickly. It is preferred over soap and water when hands are not visibly soiled according to infection control guidelines.
What is the maximum recommended dose of lidocaine with epinephrine for a healthy adult patient?
2 mg/kg
4.4 mg/kg
9 mg/kg
7 mg/kg
The maximum dose of lidocaine with epinephrine is 7 mg/kg to prevent systemic toxicity. Staying within this limit reduces the risk of adverse cardiovascular and neurologic effects.
Which ASA classification describes a healthy adult with no systemic disease?
ASA II
ASA III
ASA IV
ASA I
ASA I is assigned to normal healthy patients without systemic disease. This classification guides treatment planning and risk assessment.
After a tooth extraction, what is the first step in post-operative care to ensure hemostasis?
Brush the extraction site immediately
Instruct the patient to bite firmly on sterile gauze
Apply a warm compress to the cheek
Rinse vigorously with mouthwash
Biting firmly on sterile gauze helps form a stable clot at the extraction site. This initial pressure is critical to achieving hemostasis and preventing bleeding.
Which local anesthetic agent has an average pulpal anesthesia duration of about 60 minutes?
Bupivacaine
Articaine
Lidocaine
Prilocaine
Lidocaine provides pulpal anesthesia for approximately 60 minutes, making it suitable for routine dental procedures. Its onset and duration balance is why it is commonly used.
Which blood pressure reading indicates that elective invasive dental treatment should be deferred?
130/85 mm Hg
140/90 mm Hg
120/80 mm Hg
180/110 mm Hg
Elective invasive procedures should be postponed if blood pressure is 180/110 mm Hg or higher. This reduces the risk of perioperative cardiovascular events.
In which situation is antibiotic prophylaxis recommended to prevent infective endocarditis?
Patient receiving a simple filling with no tissue manipulation
Patient undergoing rubber dam placement
Patient with prosthetic heart valve undergoing tooth extraction
Patient receiving a routine dental radiograph
Prophylactic antibiotics are advised for patients with prosthetic heart valves during procedures that involve gingival or periapical manipulation. This follows AHA guidelines to prevent endocarditis.
What is the minimum sterilization cycle for unwrapped hand instruments in a pre-vacuum autoclave?
10 minutes at 121°C
15 minutes at 121°C
20 minutes at 132°C
3.5 minutes at 132°C
CDC guidelines specify a pre-vacuum autoclave cycle of 3.5 minutes at 132°C for unwrapped instruments. This ensures effective sterilization while minimizing cycle time.
Which local anesthetic has the longest pulpal anesthesia duration?
Lidocaine
Bupivacaine
Mepivacaine
Prilocaine
Bupivacaine is a long-acting anesthetic that can provide up to 90 minutes of pulpal anesthesia. It is chosen for lengthy procedures or significant post-operative pain control.
What is the maximum safe dose of epinephrine in local anesthesia for a healthy adult?
0.3 mg
0.2 mg
0.5 mg
0.04 mg
Healthy adults should receive no more than 0.2 mg of epinephrine per appointment. Exceeding this dose increases the risk of cardiac complications.
Which scenario is an indication for direct pulp capping?
Tooth with pulpal necrosis
Carious exposure with irreversible pulpitis
Deep caries without exposure
Mechanical exposure of a vital pulp in a small area
Direct pulp capping is indicated when there is a small mechanical pulp exposure in an otherwise healthy pulp. This promotes healing and dentin bridge formation.
How long should a patient bite on gauze after an extraction to help achieve hemostasis?
30 - 45 minutes
5 - 10 minutes
15 minutes
1 - 2 hours
Biting on gauze for 30 - 45 minutes applies adequate pressure to form a stable clot. Shorter durations often do not achieve sufficient hemostasis.
What is the primary purpose of using a rubber dam during dental treatment?
Eliminate the need for local anesthesia
Isolate the treatment field and reduce contamination
Reduce the risk of tooth fracture
Improve the aesthetic appearance of the tooth
A rubber dam isolates the operative site, providing a dry field and reducing microbial contamination. It also improves visibility and patient safety.
What feature makes articaine unique among amide local anesthetics?
Has the longest duration of action among amides
Does not require a vasoconstrictor
Contains an ester group and is metabolized in plasma
Is effective only as a topical anesthetic
Articaine contains an ester linkage and is hydrolyzed in plasma, allowing faster clearance. This reduces systemic toxicity compared to other amides.
Which analgesic regimen is recommended for moderate post-operative dental pain?
Codeine 30 mg every 4 hours as needed
Acetaminophen 1000 mg every 4 hours alone
Ibuprofen 400 mg plus acetaminophen 500 mg every 6 hours
Aspirin 650 mg at bedtime only
Combining ibuprofen and acetaminophen provides synergistic pain relief for moderate pain. This regimen is often more effective than either agent alone.
A 65-year-old patient with uncontrolled Type 2 diabetes (HbA1c 9%) requires root canal treatment. What is the best management approach?
Proceed immediately with antibiotic coverage
Postpone treatment until glycemic control improves
Perform treatment without any modifications
Schedule treatment in the afternoon after meals
Uncontrolled diabetes impairs healing and increases infection risk, so elective endodontic therapy should be deferred. Improving glycemic control first optimizes patient outcomes.
What is the maximum safe total milligram dose of lidocaine with epinephrine for a 60 kg adult?
420 mg
300 mg
240 mg
360 mg
The maximum dose for lidocaine with epinephrine is 7 mg/kg. For a 60 kg patient, this equals 420 mg to avoid systemic toxicity.
According to CDC guidelines, which sterilization method is NOT appropriate for high-speed dental handpieces?
Steam autoclave
Chemical immersion
Dry heat
Chemical vapor
Chemical immersion can damage bearings and internal components and does not reliably sterilize handpieces. Steam autoclave, chemical vapor, and dry heat are recommended methods.
A patient had a total hip replacement 8 years ago with no complications. They need scaling and root planing. Is antibiotic prophylaxis required?
Yes, only if probing depths exceed 5 mm
Yes, amoxicillin before the procedure
No, prophylaxis is not required
Yes, clindamycin before the procedure
Prophylactic antibiotics for joint replacements are generally not recommended after the first two years in healthy patients. This aligns with ADA guidelines to avoid unnecessary antibiotic use.
Which post-operative instruction most effectively reduces the risk of alveolar osteitis (dry socket)?
Apply warm compresses intermittently
Avoid smoking or using straws for at least 48 hours
Bite on a clean tissue instead of gauze
Rinse vigorously every hour
Smoking and suction activities disrupt the blood clot and increase the risk of dry socket. Avoiding these actions for 48 hours supports stable clot retention and proper healing.
