ABSTRACT


Aim

The aim of the study was to evaluate the accuracy of root canal length measurements of primary teeth using an
electronic apex locator (EAL) and digital radiography in comparison to stereomicroscopic measurement as gold standard. MATERIALS
AND

Methods

After preparation of access cavities of twenty extracted primary molars, the teeth were embedded in alginate blocks.
Endodontic files were inserted in the root canals and the length was measured using ProPex II (Dentsply, Maillefer). When the reading
was stable for 5s a silicone stop was used for reference. The true lengths of the files were then measured using a micrometer. The gold
standard was determined by observing the tip of the file at the apical foramen under a stereomicroscope. For radiographic
measurements standard images were obtained at 30 cm source-to-object distance, and zero degrees vertical and horizontal
angulations. Radiographic images of each experimental tooth were obtained with the Digora Storage Phosphor Plates (SPP) (Soredex,
Orion Corporation, Helsinki, Finland) with the x-ray unit operating at 65 kVp and 10 mA for 0.16 seconds (Trophy Radiologie,
Vincennes, France). The radiographic root lengths were measured with the measurement tool of the Digora for Windows software. The
mean measurements of both methods were compared to the gold standard measurements using Repeated Measure ANOVA test with
Bonferroni adjustments to identify the pair-wise differences (p=0.05).

Results

The mean measurements obtained with the EAL
(14.061.89 mm) were significantly lower than measurements done with SPP images (14.241.98 mm) (p<0.05). However, when both root canal length measurement techniques were compared to stereomicroscopic measurements (gold standard), no statistically significant difference was found.

Conclusion

The EAL might be safer than digital radiography for the measurement
of root canal length in primary teeth.
