Question 1

Which type of sterile drape is commonly used for oral and maxillofacial procedures?

Accepted Answer

U-drape is commonly used in oral and maxillofacial procedures to provide a sterile field around the surgical site.

Question 2

Which countable sponge is used in oral procedures to prevent bone or tooth fragments and other foreign matter from becoming lodged in the pharynx?

Accepted Answer

Throat packs are specifically used in oral procedures to prevent bone or tooth fragments and other foreign matter from becoming lodged in the pharynx, ensuring a safer surgical environment and protecting the patient from potential complications.

Question 3

Which of the following is NOT one of the three regions of a tooth?

Accepted Answer

The three regions of a tooth are crown, neck, and root. The socket is the bony socket in which the roots of the tooth are embedded in the jawbone.

Question 4

Which procedure is performed for removal of impacted wisdom teeth?

Accepted Answer

Odontectomy is the surgical procedure specifically performed for the removal of impacted teeth, such as wisdom teeth.

Question 5

Which sequence of steps for plate fixation is CORRECT?

Accepted Answer

The correct sequence for plate fixation involves placing the plate first, then drilling one hole at a time, measuring the depth of each hole with a depth gauge to determine the correct screw length, tapping the hole if necessary (depending on whether the screws are self-tapping or require a pre-tapped hole), inserting the screw, and repeating these steps for each subsequent hole. This method ensures accurate alignment and fixation of the plate to the bone.

Question 6

What is the name of the narrow, double-angle retractor frequently used in oral procedures?

Accepted Answer

The Minnesota retractor is a narrow, double-angle retractor frequently used in oral procedures to provide visibility and access.

Question 7

What is the MOST common position for patients undergoing oral and maxillofacial procedures?

Accepted Answer

The answer of What is the MOST common position for...

Question 8

Which of the following statements regarding arch bars is CORRECT?

Accepted Answer

Arch bars are thin, malleable bars with hooks that face up for the maxilla and down for the mandible, used in the management of jaw fractures and for other maxillofacial surgical procedures to stabilize the teeth and jaw.

Question 9

How many craniofacial bones make up the orbit?

Accepted Answer

Seven craniofacial bones make up the orbit: the frontal, sphenoid, zygomatic, maxilla, palatine, lacrimal, and ethmoid bones.

Question 10

All of the following are configurations of fixation plates for maxillofacial fracture reduction EXCEPT:

Accepted Answer

The configurations of fixation plates are typically referred to as H, L, Y, T, and straight plates (not W).

Question 11

A closed ventilation system and special endotracheal tube may be used in maxillofacial procedures to reduce risk of:

Accepted Answer

A closed ventilation system and special endotracheal tube are used to reduce the risk of airway fire, which can occur during maxillofacial procedures due to the presence of flammable materials and oxygen-rich environments.

Question 12

Irrigation and what other item is used anytime the dental drill is used during odontectomy?

Accepted Answer

Suction is used to remove water and debris from the area that is being drilled during odontectomy to provide clear visibility for the dentist.

Question 13

Which radiographic technique or view shows the alveolar processes, mandible, posterior maxillary sinuses, and the zygomas?

Accepted Answer

Panoramic radiographs provide a wide-field view of the entire dental arch, including the alveolar processes, mandible, posterior maxillary sinuses, and zygomas. The other options (AP, basal, PA) do not typically include all of these structures in their imaging range.

Question 14

Coral would be classified as what type of graft material?

Accepted Answer

Coral grafts are classified as xenografts because they are derived from a species different from the recipient, specifically from marine organisms.

Question 15

Tapping of bone is done in fixation procedures to reduce:

Accepted Answer

Tapping of bone is done to create a threaded pathway in the bone for the screw to follow that reduces the amount of torque needed to insert the screw, reducing the risk of damaging the bone and making the fixation stronger. This means that tapping bone reduces the torque pressure on screws, making option B the correct choice.

Question 16

The mandible articulates with which part of the temporal bone to form the temporomandibular joint (TMJ)?

Accepted Answer

The mandible articulates with the glenoid fossa of the temporal bone to form the TMJ.

Question 17

What is the term that describes the side of teeth closest to the cheek?

Accepted Answer

The term "buccal" describes the side of teeth that is closest to the cheek. The term "alveolar" refers to the bone that surrounds and supports teeth. The term "labial" describes the side of teeth that faces the lips, and the term "lingual" describes the side of teeth that faces the tongue.

Question 18

Which of the following facial bones is the largest and strongest?

Accepted Answer

The mandible, or the lower jawbone, is both the largest and strongest facial bone. It is also the only movable bone in the skull, as it is attached to the skull by a hinge joint that allows us to open and close our mouths for speaking, eating, and breathing.

Question 19

Which teeth are located in the center front of the mouth?

Accepted Answer

Incisors are the teeth that are located in the center front of the mouth.

Question 20

Strands of wire used to attach arch bars to the upper and lower jaw should be prestretched and cut to which length?

Accepted Answer

The strands of wire used to attach arch bars to the upper and lower jaw should be prestretched and cut to a length of 10 cm. This length allows for adequate manipulation and securing of the arch bars while minimizing excess material.
