Exercise 8. Insert prepositions

1.The result of to the jaws may depend partly… the severity and partly …the fragility of the bones.

2. Periostitis due…trauma uncomplicated … fracture is generally localized.

3. The affected part of the bone is extremely tender …the touch.

4. Rest and cold applications to the injured part gen­erally are sufficient … simple periostitis.

5. Treatment is surgical, consisting … evacuation of the fluid content and curettage.

6. Minor injuries result … subluxation, some­times dislocation of the mandible may or may not be associated with fracture.

7. Depending … the char­acter of the fracture and involvement of adjacent parts, we distinguish several types of fractures.

8. Healing is by granulation, which is assisted… irrigation and packing … gauze.

Exercise 9. Approve or contradict the following statements:

1. The fragility of the bones will be allowed to produce a periostitis, traumatic cyst, or fracture.

2. Periostitis is frequently seen before surgical operations as a postoperative complication.

3. Periostitis also may follow blows to the jaws, such as occur in sport accidents, fist fights, and other facial injuries.

4. Rise of temperature does not indicate infection.

5. If there is infec­tion, drainage will be established.

6. The mandible of young patients is plastic so that trauma may cause intraosseous hemorrhage with producing a fracture.

7. Fractures of the jaws never interfere with mastication, and fractures of the maxilla predispose to infection of the maxillary sinuses.

8. The roentgen picture will be able to show the amount of displacement.
