Question 1

The most common type of fibrous dysplasia, characterized by involvement of a single bone, is referred to as:&#10;A)Paget disease.&#10;B)polyostotic fibrous dysplasia.&#10;C)monostotic fibrous dysplasia.&#10;D)central giant cell granuloma.

Accepted Answer

Monostotic fibrous dysplasia is characterized by involvement of a single bone, while polyostotic fibrous dysplasia involves multiple bones. Paget disease is a separate condition characterized by excessive bone remodeling, while central giant cell granuloma is a benign tumor-like lesion of the jawbones.

Question 2

Giant cell granulomas located in the gingiva or alveolar mucosa are referred to as central. Giant cell granulomas located within the maxilla or mandible are referred to as peripheral.&#10;A)Both statements are true.&#10;B)Both statements are false.&#10;C)The first statement is true; the second is false.&#10;D)The first statement is false; the second is true.

Accepted Answer

Both statements are false. Central giant cell granulomas are located within the maxilla or mandible, and peripheral giant cell granulomas are located in the gingiva or alveolar mucosa. Both statements are false. The first statement is also false. The second statement is also false.

Question 3

Caf&#233; au lait skin macules are associated with:&#10;A)monostotic fibrous dysplasia.&#10;B)polyostotic fibrous dysplasia.&#10;C)Paget disease of bone.&#10;D)osteomalacia.

Accepted Answer

Café au lait skin macules are a hallmark feature of polyostotic fibrous dysplasia, a condition characterized by abnormal development of bone tissue. Monostotic fibrous dysplasia may also present with café au lait spots, but is less commonly associated with them than polyostotic fibrous dysplasia. Paget disease of bone and osteomalacia are not typically associated with café au lait macules.

Question 4

Which of the following types of lesions occurs most often in black women older than 40 years of age and is characterized by disordered cementum and bone, typically affecting more than one quadrant of the maxilla and mandible, and often in the posterior area?

A)Periapical cemento-osseous dysplasia
B)Focal cemento-osseous dysplasia
C)Florid cemento-osseous dysplasia
D)Monostotic fibrous dysplasia

Accepted Answer

Focal cemento-osseous dysplasia is a benign fibro-osseous lesion that typically arises in the posterior mandible and appears as an isolated, well-delineated radiolucent-to-radiopaque lesion that is less than 1.5 cm in size. Periapical cemento-osseous dysplasia and florid cemento-osseous dysplasia are also benign fibro-osseous lesions, but they involve multiple sites and typically present as diffuse radiopaque lesions. Monostotic fibrous dysplasia is a benign developmental disorder of bone that can occur in any bone but most commonly affects the long bones and craniofacial bones, and it typically presents as a painless swelling or deformity of the affected bone.

Question 5

All of the following are benign fibrous-osseous lesions that affect the maxilla and mandible except one. Which one is the exception?&#10;A)Periapical cemento-osseous dysplasia&#10;B)Fibrous dysplasia&#10;C)Florid cemento-osseous dysplasia&#10;D)Gingival fibromatosis

Accepted Answer

Gingival fibromatosis is not a fibrous-osseous lesion that affects the maxilla and mandible. It is a rare genetic disorder characterized by overgrowth of the gingival tissue. The other three options listed are all types of benign fibrous-osseous lesions that can affect the maxilla and mandible. Periapical cemento-osseous dysplasia is a common lesion that is usually asymptomatic, while fibrous dysplasia and florid cemento-osseous dysplasia are less common lesions that can cause bone deformities and dental abnormalities.

Question 6

This 74-year-old patient presents with an enlargement of the maxilla, pain, and a chief complaint that his dentures no longer fit. Radiographic examination reveals a patchy radiolucency and radiopacity that resembles cotton wool. This is indicative of what disease of bone?

A)Osteomalacia
B)Paget disease of bone
C)Fibrous dysplasia
D)Florid cemento-osseous dysplasia

Accepted Answer

The patchy radiolucency and radiopacity resembling cotton wool is characteristic of Paget disease of bone, a condition marked by abnormal bone remodeling in which an affected bone shows areas of increased and decreased density. The enlargement of the maxilla and pain are also common symptoms of Paget disease of bone. Osteomalacia involves softening of the bones due to vitamin D deficiency, fibrous dysplasia leads to the formation of abnormal fibrous tissue in place of bone, and florid cemento-osseous dysplasia is a benign fibro-osseous lesion that typically affects the mandible or maxilla.

Question 7

Surgical treatment would most likely be recommended for a patient with _____ dysplasia.&#10;A)periapical cemento-osseous&#10;B)focal cemento-osseous&#10;C)florid cemento-osseous&#10;D)fibrous

Accepted Answer

Surgical treatment would most likely be recommended for a patient with fibrous dysplasia. Fibrous dysplasia is treated surgically by recontouring the affected bone for cosmetic reasons. No treatment exists for severe and progressive polyostotic fibrous dysplasia. No treatment is necessary for periapical cemento-osseous dysplasia once the condition is recognized. Once a definitive diagnosis has been established for focal cemento-osseous dysplasia, no further treatment is necessary. Treatment for florid cemento-osseous dysplasia is often unnecessary. However, in an edentulous patient, the sclerotic masses may perforate the mucosa, resulting in a communication between the oral environment and the underlying bone. This may lead to osteomyelitis, requiring surgical intervention.

Question 8

Which of the following statements is true of osteomalacia?&#10;A)It is the result of a deficiency in phosphate.&#10;B)In adults it may be related to various problems such as malabsorption syndrome.&#10;C)It may be treated by the use of antacids.&#10;D)Accelerated tooth eruption is associated with osteomalacia.

Accepted Answer

Osteomalacia is a condition where bones become soft and weak due to a deficiency in vitamin D or calcium. In adults, it may be related to various problems such as malabsorption syndrome, which affects the absorption of nutrients like vitamin D and calcium in the body. Treatment may involve supplementation with vitamin D and calcium, not antacids. Accelerated tooth eruption is not typically associated with osteomalacia.

Question 9

Which of the following types of lesions occurs most often in black women older than 40 years of age and is characterized by disordered cementum and bone, typically affecting more than one quadrant of the maxilla and mandible, and often in the posterior area?

A)Periapical cemento-osseous dysplasia
B)Focal cemento-osseous dysplasia
C)Florid cemento-osseous dysplasia
D)Monostotic fibrous dysplasia

Accepted Answer

Florid cemento-osseous dysplasia occurs most frequently in black women over the age of 40 and is characterized by irregular cementum and bone in multiple quadrants of the maxilla and mandible, typically in the posterior region.

Question 10

Cementoma is a term once used for periapical cemento-osseous dysplasia. Because the disease does not represent a neoplasm, cementoma has been replaced with periapical cemento-osseous dysplasia.&#10;A)Both statements are true.&#10;B)Both statements are false.&#10;C)The first statement is true and the second is false.&#10;D)The first statement is false and the second is true.

Accepted Answer

Both statements are true. Cementoma is a term once used for periapical cemento-osseous dysplasia. Because the disease does not represent a neoplasm, cementoma has been replaced with periapical cemento-osseous dysplasia. Both statements are true, and the other options are false.
