Root Canal Treatment

Image
Root Canal Treatment Root Canal Treatment is a modern dental procedure to save a tooth in which the pulp (the living tissue within a tooth) has died or become untreatably diseased, usually as a result of extensive dental caries. Steps involved in Root Canal Treatment (1) A hole is drilled into the crown to remove all material from the pulp chamber. The root canals are then cleaned with fine-tipped instruments. The procedure is usually monitored by X-rays. (2) The cavity is washed out, and antibiotic paste and a temporary filling are packed into it. Some days later, the filling is removed and the canals are checked for sterlity. (3) When no infection can be detected, the cavity is filled with a sealing paste and/or tapering solid “point” made of gutta – percha resin mixed with zinc and bismuth oxides. The mouth of cavity is then sealed with cement. Related Topics in Zoology: Bio Zoology All Important Topics Human Physiology Introduction Nutrition Carbohydrates Poly hydroxyaldehydes...

Microbes in medicine

Microbes in medicine Back to botany topic list Microbes like bacteria and fungi produce antibiotics. The substance produced by a living organism, which inhibits the growth and metabolic activities of pathogenic organisms (mostly bacteria) without affecting the metabolism of host is called an antibiotic. Penicillin, streptomycin, aureomycin and chloromycetin are some of the examples for antibiotics. Penicillin is a well known antibiotic obtained from the blue green mold called Penicillium notatum. When it is grown in culture medium, the mycelium excretes an antibiotic substance called penicillin. The crude penicillin is recovered, purified and dehydrated. It is effective against gram-positive bacteria like Pneumonia bacteria. Streptomycin is obtained from the filamentous bacterium, Streptomyces griseus, an actinomycetes. It cures urinary infections, tuberculosis, meningitis and pneumonia. Aureomycin mis obtained from actinomycetes, Streptomyces aureofaciens. It is used as a medicine in ...
