Patients will be submitted to final radiographs and receive systemic medication with analgesic and anti-inflammatory. The evaluations will be carried out in 6 months and will be through clinical and radiographic examinations, to define the result of the treatments. Clinical examinations will be performed under artificial light through an exploratory probe (Duflex®) and clinical mirror (Duflex®). The clinical criteria to be observed are: edema, mobility, fistula and pain. The radiographic evaluations will be through periapical radiography with the aid of a radial ortho positioner (DFL®). In the radiographs will be observed the presence or absence of internal and external resorptions, as well as presence or absence of inter-radicular lesion.
