Dental Hygiene Instrumentation Quiz

What is the purpose of using an intraoral fulcrum?

• To pivot up on the fulcrum for proper adaptation

• To enhance access for hard to reach areas

• To provide stability and prevent musculoskeletal strain

• To increase lateral pressure during instrumentation

Where should you fulcrum when using an intraoral fulcrum?

• On the incisal edge of the tooth being instrumented

• On the same tooth being instrumented

• Three to four teeth away from the tooth being instrumented

• One to two teeth away from the tooth being instrumented

What is the purpose of using an extra oral fulcrum?

• To pivot up on the fulcrum for proper adaptation

• To increase lateral pressure during instrumentation

• To enhance access for hard to reach areas

• To provide stability and prevent musculoskeletal strain

How is a reinforced fulcrum used?

• By cupping the chin of the patient

• By placing the index finger of the non-dominant hand near the area being instrumented

• By placing the finger on the non-dominant hand on the lower shank of the instrument

• By placing the fulcrum on the opposite arch being instrumented

What is the purpose of using a finger on finger fulcrum?

• To increase lateral pressure during instrumentation

• To enhance access for hard to reach areas

• To provide stability and prevent musculoskeletal strain

• To pivot up on the fulcrum for proper adaptation

How is opposite arch fulcruming achieved?

• By placing the fulcrum on the same arch being instrumented

• By placing the fulcrum on the opposite arch being instrumented

• By placing the fulcrum on the opposite quadrant being instrumented

• By placing the fulcrum on the incisal edge of the tooth being instrumented

What is the best method for preventing musculoskeletal strain?

• Reinforced fulcrum

• Finger on finger fulcrum

• Extra oral fulcrum

• Intraoral fulcrum

Where should you hold the instrument handle when using an extra oral fulcrum?

• On the opposite arch being instrumented

• On the incisal edge of the tooth being instrumented

• Farther away from the working end

• Close to the working end

What is the risk associated with using an extra oral fulcrum?

• Increased risk of developing musculoskeletal strain

• Increased risk of damaging the tooth being instrumented

• Increased risk of injury to the patient or operator

• Increased risk of slipping inside the oral cavity

How does a finger on finger fulcrum provide stability?

• By increasing lateral pressure during instrumentation

• By enhancing access for hard to reach areas

• By resting the fulcrum finger on the index finger of the non-dominant hand

• By pivoting up on the fulcrum for proper adaptation
