Question 1

When the jaws are in centric relation, what is the term for the relationship between the teeth?

Accepted Answer

Intercuspal position

Answer

Balanced occlusion

Answer

Habitual occlusion

Answer

Maximum intercuspation

Question 2

What is the primary function of the temporomandibular joint?

Accepted Answer

To provide a pivot for mandibular movements.

Answer

To allow for speech and swallowing.

Answer

To protect the brain from trauma.

Answer

To store saliva.

Question 3

Which type of occlusion is characterized by contact between only the incisors and canines?

Accepted Answer

Anterior occlusion

Answer

Centric occlusion

Answer

Eccentric occlusion

Answer

Protrusive occlusion

Question 4

What is the significance of the 'freeway space' in dentistry?

Accepted Answer

It allows for the tongue to rest.

Answer

It helps prevent tooth wear.

Answer

It indicates the vertical dimension of occlusion.

Answer

It is necessary for swallowing.

Question 5

Which of the following is NOT a factor that determines occlusal vertical dimension in adults?

Accepted Answer

Age

Answer

Facial height

Answer

Interincisal distance

Answer

Freeway space

Question 6

How does electromyography (EMG) contribute to the analysis of muscle activity during different mandibular movements?

Accepted Answer

EMG measures electrical signals from muscles, revealing their activation patterns during mandibular movements.

Answer

EMG is primarily used to diagnose temporomandibular joint (TMJ) disorders.

Answer

EMG is the main method for determining the ideal vertical dimension of occlusion.

Answer

EMG is not useful in evaluating muscular activity during mandibular movements.
