In vitro evaluation of the accuracy of two electronic apex locators.

Chopra V, Grover S, Prasad SD - J Conserv Dent (2008)

Bottom Line: This study involves evaluating the accuracy of two electronic apex locators (EALs), Raypex and Neosono Co-pilot.The results obtained with each EAL were in turn compared with the corresponding control length.The statistical analysis of the results showed that EAL reliability in detecting the apex varies from 80 to 85% for Neosono systems and 85 to 90% for the Raypex systems.

ABSTRACT
This study involves evaluating the accuracy of two electronic apex locators (EALs), Raypex and Neosono Co-pilot. Ten single-root human anterior teeth were used for the study. The crown was sectioned to gain access to the root canal. For each tooth, the reference (or control) length, corresponding to the actual length, was determined, after which all the teeth were measured independently. The results obtained with each EAL were in turn compared with the corresponding control length. The statistical analysis of the results showed that EAL reliability in detecting the apex varies from 80 to 85% for Neosono systems and 85 to 90% for the Raypex systems. Combined with a high observer concordance, these results suggest that electronic root canal measurement can be an objective and acceptably reproducible technique.

Figure 0004: File upto apical foramen

Mentions: Based on the two possible points of terminating instrumentation i.e. the dentinocemental junction [Figure 3] and the apical foramen [Figure 4], it should be taken into account that systematic working to the apical constriction entails the risk of leaving tissue remains within the apical region and also that as this tissue may be diseased and may lead to the failure of the treatment.[13]
