# In Vitro Accuracy of Two Different Electronic Apex Locators Under Various Conditions
## 5 Conclusions  
Canal irrigants have an impact on the accuracy of apex locators. The apex locators showed an accuracy of 80% and greater when 0.9% saline and Chlorcl solutions were used. The limitations of this research are that the experimental model cannot fully duplicate the biological tissue and complexity of root canals in clinical work; therefore, greater deviations in accuracy are likely to occur in clinical work. Despite the EAL manufacturer's claims of accurate and precise measurements with various canal irrigants and the fact that they are sold on the dental market today, we suggest that more studies analyzing the accuracy of different EALs under various conditions are performed.
