The risk is considerably higher for extractions in the mandible (lower jaw) than other areas of the mouth, and the risk increases if you have been taking it for four or more years [12] Although this side effect is uncommon (0.4-1.6% for oral alendronic acid), it occurs primarily in patients being administered intravenous bisphosphonates, with ...
Long-term treatment with bisphosphonates produces anti-fracture and bone mineral density effects that persist for 3–5 years after an initial 3–5 years of treatment. [2] The bisphosphonate alendronate reduces the risk of hip, vertebral, and wrist fractures by 35-39%; zoledronate reduces the risk of hip fractures by 38% and of vertebral ...
Senile osteoporosis has been recently recognized as a geriatric syndrome with a particular pathophysiology. There are different classification of osteoporosis: primary, in which bone loss is a result of aging and secondary, in which bone loss occurs from various clinical and lifestyle factors. [1]
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

[15] [16] [27] [28] The mean life-span of osteocytes has been estimated to be 15 years in cancellous bone, [29] and 25 years in cortical bone. [ 30 ] while the average lifespan of human osteoclasts is about 2 to 6 weeks and the average lifespan of osteoblasts is approximately 3 months. [ 31 ]
This type of drug has a high affinity for hydroxyapatite [28] and stays in bone tissue for a long period of time, [29] with alendronate, it has a half-life of approximately ten years. [ 30 ] The risk of a patient having MRONJ after discontinuing this medication is unknown.
15% (50 year olds), 70% (over 80 year olds) [7] Osteoporosis is a systemic skeletal disorder characterized by low bone mass , micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk.
Bone mineral density (BMD) is a measure commonly used to quantify bone health. A lower BMD value indicates an increased risk of an osteoporosis or a fracture. [13] There is a large range of factors influencing BMD. Protein consumption has shown to be beneficial for bone density by providing amino acid substrates necessary for bone matrix formation.
