Recountouring of the residual ridge in the early part of extraction period occurs primarily by resorption of the
1) Buccal-lingual cortical bone
2) Labial-buccal cortical bone
3) Lingual cortical bone
4) Crestal bone

Oral Surgery Answer: 2

Most objective way to delete sharp ridges of bone while performing alveoloplasty is
1) Place a finger over the body ridge and palpate
2) Place a finger over the soft tissue flap and palpate

In the extraction of mandibular third molars, the main reason why the posterior incision should be placed more buccally is
1) To prevent damage to lingual nerve
2) Incision should be on the sound bone
3) To prevent damage to retromolar artery
4) All of the above

Oral Surgery Answer: 4

The use of medical history in extraction patients is
1) In medicolegal cases
2) To asses the growth stage of a patient
3) To determine bleeding disorder
4) To determine communicable disease

Oral Surgery Answer: 3

A surgical procedure required bilateral block. A bilateral inferior alveolar nerve block is
1) Not contraindicated
2) Should rarely be preformed
3) May cause space infection
