  • A. Fibrous Dysplasia
  • B. Acromegaly
  • C. Paget's disease
  • D. Rickets

Explanation: Paget disease in an older adult can cause enlargement and expansion of the maxilla, producing facial and jaw changes.

Correct answer: Paget's disease
  • A. Surgical excision
  • B. Removal of adjacent teeth
  • C. Irradiation of the lesion
  • D. Conservative surgery

Explanation: Fibrous dysplasia is usually managed conservatively, with contouring or other limited surgery when function or appearance requires it.

Correct answer: Conservative surgery
  • A. Achondroplasia
  • B. Pituitary dwarfism
  • C. Acromegaly
  • D. Cretinism

Explanation: Achondroplasia produces disproportionate short-limb dwarfism, a prominent forehead, and relative midface or maxillary retrusion, while…

Correct answer: Achondroplasia
  • A. Thin and long
  • B. Thick and short
  • C. thin and short
  • D. Fused

Explanation: In cleidocranial dysplasia, permanent teeth are often unerupted and may have short, slender roots.

Correct answer: thin and short
  • A. Cleidocranial dysostosis
  • B. Ectodermal dysplasia
  • C. Gardner's syndrome
  • D. Osteogenesis imperfecta

Explanation: Gardner syndrome combines multiple osteomas, epidermoid or sebaceous cysts, and numerous impacted supernumerary teeth.

Correct answer: Gardner's syndrome
  • A. Primary hyperparathyroidism
  • B. Metastatic bone disease
  • C. Osteomalacia
  • D. Paget's disease of the bone

Explanation: An isolated marked rise in alkaline phosphatase with normal calcium, phosphate, and liver tests in an elderly patient strongly suggests…

Correct answer: Paget's disease of the bone
  • A. Osteopetrosis
  • B. steomyelitis
  • C. condensing osteitis
  • D. Osteomalacia

Explanation: Albers-Schönberg disease is the classic name for osteopetrosis, a disorder in which defective bone resorption produces abnormally dense…

Correct answer: Osteopetrosis
  • A. Osteogenesis imperfecta
  • B. Osteopetrosis
  • C. Osteochondroma
  • D. Hyperparathyroidism

Explanation: Osteopetrosis causes defective osteoclast-mediated resorption, producing diffusely radiopaque bones that are paradoxically brittle and…

Correct answer: Osteopetrosis
  • A. Klinefelter's syndrome
  • B. Trisomy 21
  • C. Down's syndrome
  • D. Cleidocranial dysostosis

Explanation: Multiple impacted supernumerary teeth with the ability to approximate the shoulders strongly indicates cleidocranial dysostosis, which…

Correct answer: Cleidocranial dysostosis
  • A. Osteogenesis imperfecta
  • B. Osteoporosis
  • C. Osteitis deformans
  • D. Osteitis fibrosa cystic

Explanation: Osteogenesis imperfecta results from defective type I collagen and classically produces fragile bones, blue sclerae and opalescent or…

Correct answer: Osteogenesis imperfecta
  • A. Osteomalacia
  • B. Paget's disease
  • C. Fibrous dysplaisa
  • D. Osteogenesis imperfecta

Explanation: Paget disease can enlarge the maxilla and skull, while excessive bone around the optic and auditory foramina may cause visual impairment…

Correct answer: Paget's disease
  • A. Traumatic arthritis
  • B. Trigeminal neuralgia
  • C. Myofacial pain dysfunction syndrome
  • D. Degenerative arthritis

Explanation: Myofascial pain dysfunction syndrome is the commonest source of pain involving the muscles of mastication and the TMJ region.

Correct answer: Myofacial pain dysfunction syndrome
  • A. None of the above
  • B. Subluxation
  • C. Dislocation
  • D. Fibrous ankylosis

Explanation: Rheumatoid inflammation of the TMJ can destroy the condyle and lead to fibrous ankylosis, producing restricted mandibular movement.

Correct answer: Fibrous ankylosis
  • A. Pagets disease
  • B. Osteopetrosis
  • C. Cherubism
  • D. Fibrous dysplasia
  • E. A and D

Explanation: Alkaline phosphatase rises with increased bone turnover, as in Paget disease and fibrous dysplasia.

Correct answer: A and D
  • A. Rheumatoid arthritis
  • B. Osteoarthritis
  • C. Childhood illness
  • D. Trauma

Explanation: Trauma is the commonest cause of TMJ ankylosis because intra-articular bleeding and scarring can fuse the condyle to the temporal bone.

Correct answer: Trauma
  • A. Retrognathia
  • B. Periodontal disease
  • C. Premature loss off deciduous teeth
  • D. Delayed eruption of deciduous teeth

Explanation: Down syndrome is associated with midface hypoplasia and a relative mandibular prognathism, not true retrognathia.

Correct answer: Retrognathia
  • A. Infratemporal space infection
  • B. Muscular overextension and over contraction
  • C. Auriculotemporal neuritis
  • D. Otitis media

Explanation: Myofascial pain dysfunction is chiefly related to abnormal muscle activity, including overextension and sustained contraction of the…

Correct answer: Muscular overextension and over contraction
  • A. Osteogenesis imperfecta
  • B. Cherubism
  • C. Fibrous dysplasia
  • D. Paget's disease

Explanation: A cotton-wool radiographic pattern combined with raised alkaline phosphatase strongly indicates Paget disease, reflecting disorganized…

Correct answer: Paget's disease
  • A. Paget's disease of bone
  • B. Albright's syndrome
  • C. Osteomalacia
  • D. Osteogenesis imperfecta

Explanation: Paget disease of bone can rarely undergo sarcomatous transformation, classically to osteosarcoma or fibrosarcoma.

Correct answer: Paget's disease of bone
  • A. Osteopetrosis
  • B. Central giant cell granuloma
  • C. Paget's disease of the bone
  • D. Polyostotic fibrous dysplasia

Explanation: Central giant cell granuloma is typically a solitary lesion affecting one bone.
