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...
