LAGE-MARQUES, José Luiz; PROKOPOWITSCH, Igor and ANTONIAZZI, João Humberto. CUSTOMIZED RADIOGRAPHIC POSITIONER TO CONTROL ENDODONTIC TREATMENT. Rev Odontol Univ São Paulo [online]. 1997, vol.11, n.4, pp.-. ISSN 0103-0663. http://dx.doi.org/10.1590/S0103-06631997000400011.
The study of images of teeth under endodontic treatment, as well as neighboring structures, favours the early identification of the alterations that may jeopardize a prognosis of success. The perfect radiographic information and the correct interpretation guide the therapeutic approach, enhancing the relationship between pathology and healing. Due to the importance of this procedure, the authors show an instrument that, coupled to any commercial positioner, allows similar image taking under the aspect of its dimensions. The importance of this fact derived from the need of comparing the images obtained during treatment. Clinical studies indicated that the customized positioner, obtained by means of impression with heavy material, increasingly benefited the comparative analysis of areas on the external root surface with cementum-dentin resorption, such as dental trauma sequela and regions with periapical bone rarefaction during the evaluation of the new bone formation.
