Resumo
The use of calcium hydroxide far more than 90 years in the field of endodontics has established its safety limiting its adverse effects to localized effects. However, its high pH and a certain degree of cytotoxicity make it a non-biocompatible material per se. The reported adverse effects derived from the extrusion of calcium hydroxide to the periapex, though few, are quite varied: granulomas and cysts within the maxillary sinus, necrosis of the mucous membrane through direct contact, paresthesia or hypoesthesia of the lower dental nerve, including severe facial necrosis. The factors that have an impact on the extrusion and that contribute negatively to the formation of the lesions are the density of the Ca (OH)2 preparation, the insertion methods, determining anatomic factors, the iatrogenic situations to take into account and the intentions of the operator due to the medical recommendation. In this paper recommendations are made far the prevention and early treatment of these problems in pursuit of safety of the dental patient.
