ABSTRACT

Bioceramic-based dentin replacement and repair materials are mainly calcium silicate and calcium phosphate compounds which exhibit biocompatibility due to their similarity with biological compounds, like hydroxyapatite and have the ability to induce a regenerative response in the organism. For older academics or clinicians, this change might be viewed as the death of conventional dental materials, but for most others, this is the birth of true biomaterials. Mineral trioxide aggregate has been a revolutionary material in endodontics. Since its introduction in the 1990s several studies have demonstrated its use in various clinical applications. Indications were primary/secondary root canal infection, traumatic dental injury, root resorptions, combined endodontic lesions, single-visit apexification, apical/periodontal surgery. New materials, such as OrthoMTA (BioMTA, Seoul, Korea) are newly developed mineral trioxide aggregate cement for root canal obturation. According to the manufacturer, orthograde mineral trioxide aggregate grafting technique is called ?Biofilling? of the root canal system with OrthoMTA. The purpose of the report was to compose fully documented cases treated with the orthograde mineral trioxide aggregate canal grafting technique in teeth with large periapical lesions and then the treatment is finished and the prognosis is presented.
