Objective The purpose of this research was to follow the radiolucent area (pixels) in the furcation area and the behavior of the endodontically treated deciduous molars with different simplified echniques. Methods The treatments were performed without the duct instrumentation using relative isolation and two drugs were applied, as follows: G1: Guedes- Pinto paste (GP) and G2: CTZ paste (CTZ) for the pulp chamber filling. The radiolucent areas in the furcation region of deciduous molars were obtained from previous x-rays, after 6 and 12 months of the endodontic treatment and was analysed by l Image Tool 3.0 by two blinded examiners. In order to analyse the calibration between the examiners, Kappa test was used and for comparison of the initial radiographic image, analysis of variance was used after 6 and 12 months of each group and Tukey spost-hoc test. T-Student test was used for comparison between groups. Results There was a reduction of radiolucent area after 6 (p<0.01) and 12 months (p<0.01) in the teeth treated with CTZ paste. In the teeth treated with PG there was not reduction of radiolucent area after 12 months. (p= 0,09). Conclusion Although the clinical signs were similar in both groups after 12 months of follow up, only teeth treated with CTZ showed reduction of radiolucent area in the furca area after 6 and 12 months.
