    • Cadmium
    • BACKGROUND Cadmium (Latin cadmia meaning calamine) a chemical element with the symbol Cd and atomic number 48. Cadmium is a soft, malleable, ductile, bluish-white divalent metal It is a by product of zinc Is similar to zinc and mercury
    • BACKGROUND found in some paints, batteries and at other industrial workplaces. Cadmium is absorbed through inhalation of the larger particles of ore or the smaller particles of dust. 25%of ingested cadmium is absorbed and transported by the blood into the liver and kidneys. Cadmium can stay in the blood for up to two years.
    • DENTAL CORRELATIONPERIODONTITIS Cadmium is released from intra-oral alloys in dental patients and is accumulated in both teeth and oral tissues the intermetallic compound of dental amalgam contains approximately 4.5 μg/g Cd in the metal–matrix alloy. levels of Cd in tooth specimens were significantly higher in samples with dental amalgam fillings. Cd released from dental alloy restorations may influence many aspects of mineralized hard tissue of teeth and their immediate surrounding periodontal tissues.YELLOWING of TEETH Caused by chronic exposure to Cadmium(Cd)
    • Itai Itai Disease Itai-itaidisease: a form ofcadmiumpoisoning. Female workersfrom Japan whoworked in BatteryFactories sufferedfrom Cadmiumpoisoning, theydeveloped kidneyrelated diseases andosteomalacia.
    • Cadmium poisoning 3 STAGES1. Mild stage - with the renal tubular dysfunction and decreased bone mass.2. Typical stage - with the severe renal tubular dysfunction and pseudofracture detectable by X-ray examination3. Serious stage -with severe renal dysfunction and pseudofracture or fracture.
    • PREVENTION Do not live near hazardous waste sites or industrial factories that emit cadmium into the air Do not work in a metal smelting and/or refining plant Do not work in a plant that produces cadmium products (batteries, coatings, plastics, pigments)
    • TREATMENTMild Treated as outpatients. They were provided with increased dairy products and given vitamin D tablets. With this treatment, their pain decreased within two months and after four months they were able to return to work.Moderate to severe Kept in the hospital and given shots of vitamin D and taken into the sun as much as possible. After they were discharged, they had to receive vitamin D shots for one to two years. In most cases, patients’ pain subsided after two months and by eight months their bone structure had recovered enough for them to walk again.
    • TREATMENT To aid in the removal of cadmium a chelating agent can be used. The agent will help bond the excess metals in the bloodstream which will speed up the removal of the excess cadmium. Hemodialysis can also be used to remove the toxins from the bloodstream.
