Question 1

A periosteal reaction consisting of concentric layering of expanding cortical bone known as &#34;onion skin&#34; is most often associated with which of the following?&#10;A) Hyperparathyroidism&#10;B) Burkitt's lymphoma&#10;C) Garr&#233;'s osteomyelitis&#10;D) Ameloblastoma&#10;E) Odontogenic keratocyst

Accepted Answer

The "onion skin" periosteal reaction is characteristic of Garré's osteomyelitis, which is a type of chronic osteomyelitis.

Question 2

Jaw pain is a feature most often associated with:&#10;A) Periapical granuloma&#10;B) Periapical cemento-osseous dysplasia&#10;C) Periapical abscess&#10;D) Odontogenic keratocyst&#10;E) Dentigerous cyst

Accepted Answer

Periapical abscess is most often associated with jaw pain due to the accumulation of pus at the apex of a tooth root, leading to inflammation and discomfort.

Question 3

A patient has severe tooth-associated pain. The tooth is sensitive to percussion. A radiograph shows only slight thickening of the apical periodontal membrane space. The tooth shows no response to electric pulp testing. This is most likely which of the following?

A) Chronic pulpitis
B) Periapical granuloma
C) Periapical abscess
D) Periapical cyst
E) Osteosarcoma

Periapical abscess

Accepted Answer

The lack of response to electric pulp testing indicates necrosis of the pulp tissue, which, combined with severe pain and sensitivity to percussion, suggests an acute condition rather than a chronic one. The slight thickening of the apical periodontal membrane space seen on the radiograph is consistent with an inflammatory response, pointing towards a periapical abscess.

Question 4

Low-grade intrabony inflammation is a primary factor in the stimulation of which of the following lesions?&#10;A) Focal sclerosing osteitis&#10;B) Lateral root cyst&#10;C) Dentigerous cyst&#10;D) Acromegaly&#10;E) Fibrous dysplasia

Accepted Answer

Focal sclerosing osteitis, also known as condensing osteitis, is a type of chronic osteomyelitis that is often associated with low-grade intrabony inflammation, typically in response to dental caries or chronic dental pulpitis.

Question 5

A 10-year-old boy was seen because of a bony hard swelling of his left jaw. A panographic radiograph showed a mottled lucency associated with grossly carious tooth no. 19. He also had low-grade, intermittent pain associated with the tooth for the past year. This description best fits which of the following?

A) Acute osteomyelitis
B) Garré's osteomyelitis
C) Focal sclerosing osteomyelitis
D) Diffuse sclerosing osteomyelitis
E) Malignancy

Accepted Answer

Garré's osteomyelitis, also known as chronic osteomyelitis with proliferative periostitis, is characterized by a bony hard swelling and is often associated with a carious tooth and low-grade pain, fitting the description provided.

Question 6

Garr&#233;'s osteomyelitis is usually associated with which of the following?&#10;A) Trauma to the jaws&#10;B) Immune dysfunction&#10;C) Gingivitis&#10;D) Actinomycotic infection&#10;E) Decayed mandibular molar

Accepted Answer

Garré's osteomyelitis, also known as chronic osteomyelitis with proliferative periostitis, is often associated with a decayed mandibular molar, leading to a low-grade infection that causes the periosteum to react and form new bone.

Question 7

Bisphosphonates have been shown to be effective in the treatment of all the following except:&#10;A) Hypercalcemia of malignancy&#10;B) Osteoporosis&#10;C) Salivary gland malignancies&#10;D) Metastatic cancers to bone&#10;E) Multiple myeloma

Accepted Answer

Bisphosphonates are effective in treating conditions related to bone metabolism and resorption, such as hypercalcemia of malignancy, osteoporosis, metastatic cancers to bone, and multiple myeloma. They are not used for treating salivary gland malignancies, as these do not directly involve bone metabolism or resorption.

Question 8

When an inflammatory process of the jaws results in reduplication of the periosteum, as well as medullary bone inflammation, the condition is known as:&#10;A) Acute osteomyelitis&#10;B) Diffuse sclerosing osteomyelitis&#10;C) Condensing osteitis&#10;D) Garr&#233;'s osteomyelitis&#10;E) Focal sclerosing osteomyelitis

Accepted Answer

Garré's osteomyelitis is characterized by the inflammatory process of the jaws that leads to the reduplication of the periosteum and inflammation of the medullary bone.
