Aim: Comparison of the effect of QMix, 7% maleic acid and 2.5% sodium hypochlorite on the accuracy of Root ZX II and Root ZX Mini apex locator. Methodology: 45 single rooted teeth were decoronated. Patency was checked and coronal flaring was done. They were then divided into 3 groups: i) QMix, ii) 7% Maleic acid and iii) 2.5% Sodium hypochlorite. The actual length of each tooth was determined before embedding them in an alginate model. 5ml of the respective irrigant was introduced into the canal. Working length was measured with Root ZX and Root ZX Mini apex locators. For each sample, an average of a total of three readings was considered. Statistical analysis was performed using Anova, Two Way, Post hoc, Paired t-tests. Results: Group I (QMix) showed no statistically significant results. Group II (7% Maleic acid), showed statistically significant difference from the actual length with Root ZX Mini (p=0.002). Group III (2.5% sodium hypochlorite) showed statistically significant difference from the actual length with Root ZX II (p=0.04) and Root ZX Mini (p=0.0002). A statistically significant difference was seen in the readings by both the apex locators (p=0.005). Conclusion: QMix does not affect the accuracy of apex locators. Root ZX II is more accurate than Root ZX Mini in the presence of 7% maleic acid and 2.5% sodium hypochlorite.
