Question 1

The temporomandibular joint exhibits ginglymoarthrodial, or ____________ movement.

Accepted Answer

The temporomandibular joint exhibits both rotational and translational movements, making it a ginglymoarthrodial joint. This allows for the opening, closing, and maximal interdigitation of the mandible with the temporal bone.

Question 2

Which of the following statements is characteristic of a patient with osteoarthritis?

Accepted Answer

B

Question 3

Synovial __________ is the most common benign neoplasm of the synovium.

Accepted Answer

Synovial chondromatosis is the most common benign neoplasm of the synovium. It is characterized by the development of metaplastic, highly cellular cartilaginous foci in the synovial membrane that results in degenerative changes consistent with osteoarthritis. It is characterized by swelling, pain, and limitation of movement. Synovial chondromatosis and not osteoblastoma is the most common benign neoplasm of the synovium. Synovial chondromatosis and not chondroblastoma is the most common benign neoplasm of the synovium. Synovial chondromatosis and not osteoma is the most common benign neoplasm of the synovium.

Question 4

The temporomandibular joint is the articulation between the condyle of the mandible and the:

Accepted Answer

The temporomandibular joint is formed by the articulation of the condyle of the mandible with the glenoid fossa of the temporal bone.

Question 5

An open lock that the patient cannot reduce is called:

Accepted Answer

An open lock that the patient cannot reduce is called a dislocation.

Question 6

Of the various surgical techniques used to treat TMDs, ________________ involves surgical repositioning of the condyle.

Accepted Answer

Of the various surgical techniques used to treat TMDs, condylotomy involves surgical repositioning of the condyle. Arthrocentesis involves lavaging the joint through a needle. Arthroscopy allows direct visualization and manipulation of the joint. Open joint surgery is used to perform disc repositioning, replacement or excision, and total joint reconstruction using a prosthetic device or autogenous graft.

Question 7

_________________________ ankylosis is the most common type seen in the temporomandibular joint.

Accepted Answer

The answer of _________________________ ankylosis is the most common type...

Question 8

Which type of dental radiography is best for examining disk position, function, form, and the presence of joint effusions?

Accepted Answer

Magnetic resonance imaging (MRI) is the best option for examining disk position, function, form, and the presence of joint effusions in the temporomandibular joint. MRI provides detailed images of soft tissues, making it useful for diagnosing conditions in the joint. Panoramic imaging, transcranial imaging, and computed tomography (CT) are not as effective for evaluating soft tissue structures in the joint.

Question 9

About __% of all TMJ ankylosis cases result from joint infection, usually after trauma.

Accepted Answer

About 50% of all TMJ ankylosis cases result from joint infection, usually after trauma, but 30% result from trauma without infection. About 50% rather than 10% of all TMJ ankylosis cases result from joint infection, usually after trauma. About 50% rather than 30% of all TMJ ankylosis cases result from joint infection, usually after trauma. About 50% rather than 70% of all TMJ ankylosis cases result from joint infection, usually after trauma.

Question 10

While up to __% of the adult population has at least one sign and/or symptom of a temporomandibular disorder, most studies suggest that clinically significant TMD-related jaw pain, dysfunction, or both affects about __% of the general population.

Accepted Answer

The answer of While up to __% of the adult...

Question 11

Clicking and popping most commonly reflect:

Accepted Answer

Clicking and popping sounds in the jaw are most commonly associated with disk displacement with reduction in the temporomandibular joint (TMJ).

Question 12

During opening of the jaw:

Accepted Answer

During opening of the jaw, the initial movement is rotational followed by a translation of the condyle along the articular eminence. Therefore, Choice A is the correct option.

Question 13

Which of the following statements is true of the articular disk in the temporomandibular joint?

Accepted Answer

The articular disk in the temporomandibular joint is surrounded and protected by the fibrous connective tissue joint capsule, which helps maintain its position and function within the joint.

Question 14

Which of the following choices represents an indirect form of trauma affecting the temporomandibular joint?

Accepted Answer

The answer of Which of the following choices represents an...

Question 15

Children are _______ prone to TMJ ankylosis than adults because of greater osteogenic potential and ________ development of the joint meniscus.

Accepted Answer

Children are more prone to TMJ ankylosis than adults because of greater osteogenic potential and less development of the joint meniscus. Children are more prone to TMJ ankylosis than adults because of greater osteogenic potential and less rather than more development of the joint meniscus. Children are more rather than less prone to TMJ ankylosis than adults because of greater osteogenic potential and less rather than more development of the joint meniscus. Children are more rather than less prone to TMJ ankylosis than adults because of greater osteogenic potential and less development of the joint meniscus.

Question 16

Opening, or depressor function, of the mandible is accomplished primarily by the _____________ muscle.

Accepted Answer

The lateral pterygoid muscle is responsible for opening, or depressor function, of the mandible. The medial pterygoid, masseter, and temporalis muscles are involved in closing, or elevating, the mandible.
