Purpose: To assess the effectiveness of the Root Zx to determine the Cement - Dentin - Canal junction (CDC) in the presence of sodium hypochlorite 5,25% Clorox®; combined with Rc- prep. Premier® and sodium hypochlorite 5.25% Clorox® combined with EDTA 10% Eufar® in uniradicular teeth.
Material and methods: An experimental study in vitro with 12 uniradicular teeth was done. They wered divided in three groups: Grupo 1 (n = 12) sodium hypochlorite 5,25% Clorox ®; Group 2 (n = 6) sodium hypochlorite 5.25%Clorox® combined with Rc- Prep. Premier®; Group 3 (n = 6) sodium hypochlorite 5,25% Clorox ® combined with EDTA 10% Eufar®. Root ZX was used to locate the CDC; the samples were divided longitudinally, covered with gold and observed at the SEM, to corroborate the effectiveness of the instrument in the location of the CDC.
Results: The results demonstrate statistically significant differences between Root ZX and SEM in each group. In group 1, a longer measurement was obtained with the Root ZX compared with the SEM, the difference was 0.788 mm. On the other hand, in the group of the sodium hypochlorite 5,25% with EDTA 10%, a shorter measurement was obtained, (-0.766 mm) a statistically significant difference.
Conclusions: The results suggest that the Root ZX is effective in the location of the apical constriction with a level of tolerance of +/- 1 mm.
