Senile Osteoporosis (Type 2 Osteoporosis) affects men and women ____ yrs of age and older70+
Type 1 osteoporosis is due to a change in what hormone? Type 2 Osteoporosis is due to a change in what hormone?1-Estrogen (decline), 2-PTH (increase)
_____ deformity is caused by Vertebral compression fractures and is one of the hallmarks of OsteoporosisKyphotic deformity
Mandibular Cortical Index is used to asses extent of what generalized radiolucency inducing condition?Osteoporosis
greater than _____% of bone mass must be lost before bone loss apparent on radiographs30%
What is today’s most commonly used method to measure bone mineral density?Dual-energy x-ray absorptiometry (DXA)
Calcitonin, Estradiol (hormone replacement), Bisphosphonates and Selective Estrogen Receptor Modulators are treatments of what condition?Osteoporosis
in hereditary hemolytic anemias... ___ marrow is converted to ____ marrow and marrow spaces enlargeyellow --> red
Radiographic findings of thalassemia is typically associated with which?Beta Thalassemia major

condition associated with

Question Answer
due to normal age related occurrence... decrease in bone mass Too much bone resorption/not enough bone formation with insufficient matrixOsteoporosis
excess bone resorptionHyperparathyroidism
insufficient calcification of bone matrixRickets (children) or Osteomalacia (adults)
bone marrow hyperplasiaHemolytic Anemia
accelerated trabecular bone resorption associated with reduced estrogen levels is called _____ osteoporosisPost-menopausal (type 1)
_____ deficiency (hormone) increases osteoclast activityEstrogen (obviously calcitonin would too)
generalized radiolucency due to Loss of trabecular and cortical bone related to increase in cortical bone and osteoclast senescence... seen in both gendersSenile osteoporosis (type 2)
elevated levels of alkaline phosphatase, hypercalcemia, hypophosphatemia increased urinary secretion of calcium and Phosphate are all associated with what generalized radiolucency causing condition?Hyperparathyroidism
long term Kidney disease lead to what secondary condition that causes generalized radiolucency?Secondary Hyperparathyroidism
Kidney stones (Nephrolithiasis), weakness fatigue lethargy, and polyuria are associated with what generalized radiolucency inducing condition?Hyperparathyroidism
Localized lytic lesions of “brown tumors (grossly)” occur late in disease in about 10% of cases with giant cells in jaws that also have generalized radiolucency caused by what condition?Hyperparathyroidism
Ground glass appearance of jaw bone trabeculation can come from what hormonal imbalance?Hyperparathyroidism
alterations in bone morphology associated with chronic kidney disease (enlargement of bone with ground glass appearance)Renal Osteodystrophy
serum calcium increased and serum phosphate decreasedHyperparathyroidism (elevated calcium and increases extcretion of phosphate)
milkman fractures associated with what conditionOsteomalacia
same findings as osteomalacia and rickets... but with thin enamel and enlarged pulpsVit D resistant Rickets with Hypophosphatemia
Valine is substituted for glutamic acid at position 6 in the beta-subunit of hemoglobinSickle Cell Anemia
Inadequate production of hemoglobin due to inadequate production of alpha or beta globin chainsThalassemia
Larger marrow spaces with honey-comb appearance, hair-on end appearance, enlarged diploic spaceSickle cell anemia
enlargement of jaws, enlargement of marrow spaces, thickening of trabeculae, thinning of cortex and hypoplasia or absence of maxillary sinus with spiked mandibular 1st premolars and molars, hair-on-end appearanceBeta Thalassemia major
