Calcium hydroxide induces mineralized tissue neoformation: a case report

Abstract

Trauma in the anterior teeth is a relatively common occurrence during childhood, having as main consequence teeth with incomplete root development and open apices. Patient, male, leucoderma, 10 years old, attended the Dental Clinic of the Southern University of the State of Santa Catarina, reporting as main complaint fracture in the crown of element 11. After clinical and radiographic examination, it was possible to identify the incomplete apexogenesis of this tooth and the presence of necrotic pulp. Aiming to stimulate neoformation of mineralized tissue at the dental apex, the calcium hydroxide based dressing was used. He remained for eight months, always with radiographic control. Apexification was observed radiographically and proved through the use of an instrument introduced inside the canal. The use of calcium hydroxide as intracanal medication for eight months stimulated mineralized tissue neoformation in the apical region of element 11 and allowed endodontic treatment.
