Chemical analysis of the liberation of calcium and hydroxil ions of calcium hydroxcide pastes in the presence of connective tissue of the dog. Brazilian Dental Journal, Ribeirão Preto, v. 7, n. 1, p. 41-46, 1996.0103-6440http://repositorio.bc.ufg.br/handle/ri/16487The objective of this research is to chemically analyze calcium hydroxide pastes added to three hydrosoluble vehicles having different acid-base characteristics using polyethylene tubes implanted in subcutaneous connective tissue in a dog, evaluating the liberation of calcium and hydroxyl ions over a period of 7, 30, and 60 days. The three vehicles were saline, anesthetic, and polyethylene glycol 400. Chemical analysis of the liberated calcium ions was done by means of conductimetry using EDTA for titration. Liberation of hydroxyl ions was determined by analogy of calcium ions liberated, which are in direct proportion to the molecular weight of calcium hydroxide.engAcesso AbertoCalcium hydroxidePulpotomyIntracanal dressingArtigo
