Which of the following are considerations when dealing with a history of cervical muscle pathology in a dental setting? (Select all that apply.) Patients may not be able to raise the chin as requested during treatment. Additional supports and stabilizers such as pillows may make the patient more comfortable. Which of the following are considerations when dealing with a history of facial paralysis in a dental setting? (Select all that apply.) Twitching, spasms, and weakness can be evident. Reduced drooling and the usual taste sensations are evident. From the following list of lip-related movements of the orbicularis oris muscle, match those movements with their CORRECT facial action. a. With pursing lips b. With pouting and kissing c. With grimacing d. With closing lips 1. With pressing together D 2. With tightening and thinning A 3. Rolling inward between the teeth C 4. With thrusting outward B

The temporal bone and mandible come together to form the temporomandibular joint BECAUSE a joint is defined as a junction or union between two or more bones . Both the statement and the reason are correct and related. The temporomandibular joint is innervated by the maxillary nerve or second division of the fifth cranial or trigeminal nerve. And The blood supply to the joint is from branches of the external carotid artery. The first statement is false; the second is true. - The joint disc of the temporomandibular joint is a fibrous disc located between the temporal bone and the coronoid process of the mandible on each side. - This disc conforms to the shape of the bones and is related to joint movement. The first statement is false; the second is true. Mandibular another term used for articular fossa of the temporomandibular joint Mandibular notch- depression located between the condyle and coronoid process of the temporomandibular joint? Including examination of the temporomandibular joint during the extraoral examination is important to detect changes such as disc perforation BECAUSE disc perforation is commonly found in females and males during puberty. The statement is correct, but the reason is NOT. Stylohyoid ligament is NOT associated with the temporomandibular joint? Temporomandibular joint ligament -associated with the temporomandibular joint prevents excessive retraction or moving backward of the mandible Sphenomandibular ligament -associated with the temporomandibular joint is a landmark for the administration of inferior alveolar local anesthetic nerve block - The temporomandibular joint allows for movement of the mandible during speech and mastication. - Two basic types of movement are performed by the joint and its associated muscles: a gliding movement and a rotational movement. Both statements are true. The gliding movement of the temporomandibular joint allows the lower jaw to move forward or backward. What movement of the mandible is involved when the lower jaw moves forward? Protrusion What movement of the temporomandibular joint occurs MAINLY between the joint disc and the condyle of the mandible in the lower synovial cavity? Rotation - Opening the jaws during speech and mastication involves BOTH elevation and retraction of the mandible. - When the jaws close, this involves BOTH depression and protrusion of the mandible. Both statements are false. What type of temporomandibular joint movement(s) occurs during lateral deviation of the mandible or shifting of the lower jaw to one side? Gliding movement on one side and rotational movement on the other side The rest position of the temporomandibular joint is NOT with the teeth biting together BECAUSE as we observe during mastication of food, the mandible returns to the center. Both the statement and the reason are correct but NOT related.

- The dental professional plays an important role in the recognition, treatment, and maintenance of patients with temporomandibular disorder. - All signs and symptoms related to temporomandibular disorder need to be recorded by the dental professional, as well as any parafunctional habits and related systematic diseases. Both statements are true. - When examining the joint, joint sounds may be heard because of disc derangement. - Joint sounds are a reliable indicator of temporomandibular disorder. The first statement is true; the second is false. Subluxation- dislocation of BOTH the temporomandibular joints on a patient? Articular fossa - located on the temporal bone that articulates with the mandible? - The joint disc of the temporomandibular joint is attached to the lateral and medial poles of the mandibular condyle. - The disc is fully attached to the temporal bone to all sides of the bone. The first statement is true; the second is false. - As a person ages or undergoes trauma to the area, the joint disc of the temporomandibular joint can become thicker or even perforated. - Perforation can lead to clinical problems. The first statement is false; the second is true. The sphenomandibular ligament is a landmark for the administration of (long) buccal nerve block and is also involved in troubleshooting the injection due to its location. Both false. - The base of the triangular temporomandibular ligament is attached to the zygomatic process of the temporal bone and the articular tubercle; its apex is fixed to the lateral side of the neck of the mandible. - This ligament prevents the excessive protrusion or moving forward for the mandible, a situation that might lead to problems with the temporomandibular joint. The statement is correct, but the reason is NOT. The resting position of the temporomandibular joint can be noted with the teeth ___ apart at approximately 2 to 4 mm - When considering temporomandibular disorders, MOST symptoms seem to originate from the nerve surrounding the joint. - In addition, MOST recent studies support the role of temporomandibular disorders in directly causing headaches, neck or back pain, or instability. Both statements are false. If your patient has a history of impaired movement of the temporomandibular joint, what may be occurring? ( Select all that apply .) ALL OF THE ABOVE

1. From the following list of actions involving the temporomandibular joint, select those that are DIRECTLY associated with lateral deviation of the joint. (Select all that apply.) Single lateral pterygoid muscle contraction Gliding movement Rotational movement From the following list of actions, select the procedures USUALLY used during an examination of the temporomandibular joint. (Select all that apply.) Bilateral palpation of all joint movements Digital palpation of external acoustic meatus Ausculation of the joint From the following list of descriptions, select those that can occur with aging of the joint disc of the temporomandibular joint. (Select all that apply.) Thinner Perforated From the following list of descriptions, select those descriptions that can be applied to the joint capsule of the temporomandibular joint. (Select all that apply.) Wraps around articular eminence and fossa Wraps around the condyle circumference From the following list of descriptions, select those descriptions that can be applied to the stylomandibular ligament of the temporomandibular joint. (Select all that apply.) Anatomically variable ligament Formed from thickened area cervical fascia Becomes taut with mandibular protrusion If your patient has a history of impaired movement of the temporomandibular joint, what may be occurring? (Select all that apply.) Disc degeneration may be involved Calcifications may be present Joint disc may be thinner or even perforated Aging or trauma may be involved Which of the following needs to be included during an effective extraoral examination of the temporomandibular joint of a patient? (Select all that apply.) Opening and closing the mouth several times Palpating the depression inferior to the zygomatic arch
