Dentine Hypersensitivity Quiz

What is dentine hypersensitivity characterized by?

• Short, sharp pain

• Continuous dull pain

• No pain at all

• Chronic pain

Which type of stimuli can cause dentine hypersensitivity?

• Magnetic

• Auditory

• Thermal

• Visual

What is the primary nerve fiber type associated with pain perception in dentine?

• C fibers

• B fibers

• D fibers

• A fibers

Which theory of pain perception is widely accepted for dentine hypersensitivity?

• Hydrodynamic theory

• Neural theory

• Gate control theory

• Odontoblastic receptor theory

What does the hydrodynamic theory suggest about fluid movement?

• It distorts the pulpal environment

• It decreases pain response

• It only affects A fibers

• It has no effect on pain

What is the definition of pain according to the text?

• A response to external stimuli

• An unpleasant sensory and emotional experience

• An emotional experience without sensation

• A pleasant sensory experience

What anatomical structure is primarily involved in dentine sensitivity?

• Pulp

• Dentin

• Cementum

• Enamel

Which of the following is NOT a cause of dentin exposure?

• Erosion

• Attrition

• Abfraction

• Fluorosis

What is the role of odontoblasts in dentine sensitivity?

• They produce enamel

• They have no role

• They form cementum

• They are the primary receptors

What happens to the pain response when fluid moves away from the pulp-dentin complex?

• Pain decreases

• Pain is eliminated

• Pain remains the same

• Pain increases
