The efficiency and reliability of the Dentometer for detecting root canal length

Area of Science:

• Dentistry
• Medical Imaging
• Endodontics

Background:

• Accurate tooth length determination is crucial for successful endodontic treatment.
• Electronic apex locators (EALs) and radiographic methods are commonly used for this purpose.
• Comparing the accuracy of different EALs and their correlation with radiographic findings is essential.

Purpose of the Study:

• To compare the accuracy of an analog-indicating electronic device (Dentometer) and an audio-indicating electronic device (Sono-Explorer) for tooth length determination.
• To compare these electronic devices against the radiographic method.
• To assess the statistical significance of differences between the measurement methods.

Main Methods:

• Comparative study involving two electronic apex locators: Dentometer and Sono-Explorer.
• Measurements obtained from both devices were compared to each other and to the calculated working length determined radiographically.
• Statistical analysis was performed to determine significant differences between the groups.

Main Results:

• The Dentometer consistently provided shorter readings compared to the Sono-Explorer (p < 0.001) and radiographic measurements (p < 0.001).
• No statistically significant difference was observed between the Sono-Explorer readings and the calculated radiographic working length.
• Radiographic measurements tended to be longer than those obtained by the electronic methods.

Conclusions:

• The Sono-Explorer demonstrated comparable accuracy to the radiographic method for tooth length determination.
• A statistically significant difference exists between the Dentometer and Sono-Explorer, highlighting variations in electronic device accuracy.
• Further comparative studies are necessary to validate the accuracy of electronic devices against established methods.
