Which of the following is the oral cavity findings for brittle bone diseases?
- A.
Dentinogenesis imperfecta
- B.
Only primary dentitions are affected
- C.
Hypoplastic maxilla with high palatal arch and open bite
- D.
Lion-like facial deformity
Correct Answer
A. Dentinogenesis imperfectaExplanation
Dentinogenesis imperfecta is the correct answer for the oral cavity findings in brittle bone diseases. This condition affects the formation of dentin, causing the teeth to be discolored, weak, and prone to breakage. It can affect both primary and permanent dentitions. The other options mentioned, such as hypoplastic maxilla with high palatal arch and open bite, and lion-like facial deformity, are not specific to brittle bone diseases and may be associated with other conditions.Rate this question:

Scorbutic gingivitis is an oral manifestations found in people with...
- A.
Vitamin C deficiency (Scurvy)
- B.
Vitamin D deficiency
- C.
Rickets
- D.
Paget's disease of bone
Correct Answer
A. Vitamin C deficiency (Scurvy)Explanation
Scorbutic gingivitis is a condition characterized by inflammation and bleeding of the gums, and it is commonly associated with vitamin C deficiency, also known as scurvy. Vitamin C plays a crucial role in collagen synthesis, which is essential for maintaining healthy gums and connective tissues. Without an adequate intake of vitamin C, the gums become weak and prone to infection, leading to the development of gingivitis. Therefore, the correct answer is vitamin C deficiency (scurvy) because it is directly linked to the oral manifestations described.Rate this question:

All of the following is TRUE about Juvenile ossifying fibroma EXCEPT:
- A.
Associate with cranio facial fibrous dysplasia
- B.
Have two pattern histologically; trabecular and psammomatoid
- C.
Paresthesia may be noted
- D.
Well circumscribed but not encapsulated histologically
Correct Answer
A. Associate with cranio facial fibrous dysplasiaExplanation
Juvenile ossifying fibroma is a benign bone tumor that primarily affects the craniofacial region. It is not associated with craniofacial fibrous dysplasia, which is a separate condition. Juvenile ossifying fibroma can have two histological patterns, trabecular and psammomatoid. Paresthesia, a sensation of tingling or numbness, may be noted in individuals with this condition. Although the tumor is well circumscribed, it is not encapsulated histologically, meaning it does not have a distinct capsule separating it from the surrounding tissue.Rate this question:

Which of the following is TRUE regarding to fibro-osseous lesion?
- A.
Polyostic fibrous dysplasia is more common in maxilla than mandible
- B.
Monostotic fibrous dysplasia is more painful than polyostic fibrous dysplasia
- C.
Radiographically appears as ground glass in mature stage
- D.
Radiotherapy is not contraindicated
Correct Answer
C. Radiographically appears as ground glass in mature stageExplanation
Fibro-osseous lesions, including fibrous dysplasia, can be seen radiographically as a ground glass appearance in their mature stage. This refers to a hazy or cloudy appearance of the affected bone on an X-ray or CT scan. This finding is characteristic of fibro-osseous lesions and can help in their diagnosis and differentiation from other conditions. It is important to note that other radiographic features may also be present, such as cortical thickening or expansion of the affected bone.Rate this question:

All of the following statements are TRUE about cherubism EXCEPT:
- A.
The basic defect is in collagen type II
- B.
Increased alkaline phosphatase enzyme level
- C.
Surgical removal and radiation is contraindicated
- D.
It is hereditary bone diseases
Correct Answer
A. The basic defect is in collagen type IIExplanation
Cherubism is a hereditary bone disease characterized by excessive growth of the jawbones. The basic defect in cherubism is not in collagen type II, but rather in the SH3BP2 gene. This gene mutation leads to abnormal bone remodeling and the formation of cystic lesions in the jawbones. Increased alkaline phosphatase enzyme levels are commonly observed in individuals with cherubism due to the increased bone turnover. Surgical removal and radiation are contraindicated in cherubism as they can exacerbate the condition.Rate this question:

Blue sclera is evident and associated with heart valve defects are refer to which bone disease?
- A.
Osteogenesis imperfecta
- B.
Osteopetrosis
- C.
Cleidocranial dysplasia
- D.
Achondroplasia
Correct Answer
A. Osteogenesis imperfectaExplanation
Blue sclera is a condition characterized by the bluish tint in the white part of the eye. It is commonly associated with osteogenesis imperfecta, also known as brittle bone disease. Osteogenesis imperfecta is a genetic disorder that affects the production of collagen, a protein essential for bone strength. The abnormal collagen production leads to fragile bones, causing frequent fractures and deformities. Blue sclera is a result of the thinness and transparency of the sclera, allowing the underlying dark choroid to show through. Therefore, the presence of blue sclera in conjunction with heart valve defects suggests osteogenesis imperfecta.Rate this question:

All of the following are TRUE about the osteopetrosis EXCEPT:
- A.
Lack of estrogens leading to osteoclastic predominates
- B.
Transverse bands of varying density producing zebra like effect which may be seen radiographically
- C.
Associate with facial deformity leading to hypertelorism
- D.
Compression of various cranial nerve leading to blindness and deafness
Correct Answer
A. Lack of estrogens leading to osteoclastic predominatesExplanation
Osteopetrosis is a rare genetic disorder characterized by increased bone density due to defective osteoclast function. It is not caused by a lack of estrogens. The other statements are true about osteopetrosis, including the presence of transverse bands on radiographs, facial deformities such as hypertelorism, and compression of cranial nerves leading to blindness and deafness.Rate this question:

Which of the following is NOT the oral manifestation of cleidocranial dysplasia?
- A.
Enlarged pulp chambers of primary dentition
- B.
Prognathic mandible
- C.
Prolonged retention of deciduous teeth and delayed eruption of permanent teeth
- D.
Roots are short, hooked, curved and thinner than normal
Correct Answer
A. Enlarged pulp chambers of primary dentitionExplanation
Cleidocranial dysplasia is a genetic disorder that affects the development of bones and teeth. It is characterized by the delayed eruption of permanent teeth and prolonged retention of deciduous teeth. Additionally, the roots of the teeth in individuals with cleidocranial dysplasia are typically short, hooked, curved, and thinner than normal. However, enlarged pulp chambers of primary dentition are not typically associated with this condition. Therefore, the correct answer is "Enlarged pulp chambers of primary dentition."Rate this question:

Which bone disease give clinical features of curved lower spine which is a condition that called as lordosis and leading to kyphosis?
- A.
Achondroplasia
- B.
Mc-Cune Albright syndrome
- C.
Ossifying-fibroma
- D.
Paget's bone disease
Correct Answer
A. AchondroplasiaExplanation
Achondroplasia is a bone disease that causes abnormal growth and development of the bones, particularly the long bones in the arms and legs. One of the clinical features of achondroplasia is a curved lower spine, which is known as lordosis. This abnormal curvature of the spine can lead to kyphosis, a condition characterized by a rounded upper back. Therefore, achondroplasia is the correct answer for the given question.Rate this question:

Which of the following is a TRUE statement?
- A.
Letterer-Siwe is the chronic disseminated form of the disease
- B.
Electron microscope finding of Birebeck granules structure that found in Hand-Schuller-Christian diseases
- C.
Dowager's hump result in gigantism patients due to their height
- D.
Hpercalcaemia is manifested by poor muscle tone of a patient with hyperparathyroidism
Correct Answer
D. Hpercalcaemia is manifested by poor muscle tone of a patient with hyperparathyroidismExplanation
Hypercalcemia is a condition characterized by high levels of calcium in the blood. One of the manifestations of hypercalcemia is poor muscle tone, which refers to decreased muscle strength and control. This can result in muscle weakness and fatigue. Hyperparathyroidism is a condition where the parathyroid glands produce excessive amounts of parathyroid hormone, leading to increased calcium levels in the blood. Therefore, it is true to say that hypercalcemia is manifested by poor muscle tone in a patient with hyperparathyroidism.Rate this question:
