Abstract

Objective: The aim of this research was to appreciate the
effects of different file sizes and the presence of calcium hydroxide on the
correctness of the electronic apex locator (EAL) at simulated immature teeth.

Methods: In this study, 30 maxillary central teeth were used
beforehand extracted due to periodontal reasons. The actual root canal length
determined with K-File and measured behind 0.5mm from the apex. In order to
simulate an immature tooth, the apical of roots were prepared with a diameter
of 1,4mm Gates-Glidden drills and K-Files. Working lengths of samples were
measured using the Root ZX by 110-140 K-Files. Each measurement was repeated
three times and averaged. Then all the samples were filled with calcium
hydroxide medicament and working lengths were determined by the same method.
Statistical analysis was performed using the Two-way ANOVA.

Results: The measurements were closer to the actual root
canal length as the diameter of the file increased at the presence and absence
of calcium hydroxide. However, there was a difference between the presence and
absence of calcium hydroxide in the determination of root canal length.

Conclusions: In these experimental study conditions, it was
concluded that the presence of calcium hydroxide in simulated immature teeth and
file size affect the EAL.
