Mohamed oral surgery

  1. 1. 7.The most logical explanation for causing swelling beneath the eye caused by an abscessed maxillary canine is that the  A. lymphatics drain superiorly in this region.  B. bone is less porous superior to the root apex.  C infection has passed into the angular vein which has no valves  D the root apex lies superior to the attachment of the caninus and levator labii superioris muscles.   192 a long maxillary canine root allows infection to erode through the bone superior to the insertion of the levator anguli oris muscle and causes an infraorbital (canine) space infection. page 294
  2. 2. 192 4. Which of the following is NOT a sign or symptom of the myofascial pain dysfunction syndrome?  A. Pain.  B. Muscle tenderness.  C. Limitation of jaw motion.  D. "Clicking" or "popping" noise in the joints.  E Radiographic changes of the joint. E.  page 633
  3. 3. 193 1.Excessive formation of scar tissue beyond the wound margin is called  A. a fibroma.  B. a keloid.  C. a fibro-epithelial polyp.  D. epithelial hyperplasia. Factors making scars noticeable include hypertrophy or keloids, page 576
  4. 4. 192 4. A periapical infection of a mandibular third molar may spread by direct extension to the 1. parapharyngeal space. 2. submandibular space. 3. pterygomandibular space. 4. submental space.  A. (1) (2) (3)  B. (1) and (3)  C. (2) and (4)  D. (4) only  E. All of the above. Page 327
  5. 5. 192 6. 5. The most likely complication associated with the extraction of an isolated maxillary second molar is  A. a dry socket.  B. nerve damage.  C. fracture of the malar ridge.  D. fracture of the tuberosity. The maxillary tuberosity fractures most commonly result from extraction of an erupted maxillary third molar or from extraction of the second molar if it is the last tooth in the arch. Page 192
  6. 6. 192 6. A patient presenting with diplopia, exophthalmos, nasal bleeding and swelling, may suffer from a fracture of the  A. neck of the condyle.  B. body of the mandible.  C. zygomatic bone.  D. maxillary tuberosity.
  7. 7. 193 If an odontogenic infection involves the pterygomandibular space, the most obvious clinical sign will be  A. trismus.  B. facial swelling.  C. swelling in the submandibular area  . D. rise in body temperature above 39 c (102ºF). When the pterygomandibular space alone is involved, little or no facial swelling is observed; however, the patient almost always has significant trismus Page 328
  8. 8. 194 4.Trismus is most frequently caused by  A. tetanus.  B. muscular dystrophy.  C. infection.  D. mandibular fracture. Another important sign is trismus, which is the inability to open the mouth widely. In odontogenic infections, trismus results from the involvement of the muscles of mastication in the inflammatory process. Mild trismus can be defined as a maximum interincisal opening between 20 and 30 mm; moderate trismus is between 10 and 20 mm; and severe trismus is an interincisal opening of less than 10 mm. Page 299
  9. 9. 196 5. When sutures are used to reposition tissue over extraction sites, they should be 1. placed over firm bone where possible. 2. interrupted, 15mm apart. 3. firm enough to approximate tissue flaps without blanching. 4. tight enough to produce immediate hemostasis.  A. (1) (2) (3)  B. (1) and (3)  C. (2) and (4)  D. (4) only  E. All of the above.
  10. 10. 196 4. An acute periapical abscess originating from a mandibular third molar generally points and drains in the  A. submandibular space.  B. pterygomandibular space.  C. buccal vestibule.  D. buccal space. third molar infections almost always erode through the lingual cortical plate. The mylohyoid muscle determines whether infections that drain lingually go superior to that muscle into the sublingual space or below it into the submandibular space. Page294determines whether infections that drain
