Clinical evaluation of a new method for determining tooth length without radiographs

Area of Science:

• Dentistry
• Endodontics
• Medical Instrumentation

Background:

• Traditional methods for measuring tooth length in endodontics often rely on radiographs.
• Radiographic methods present challenges, including radiation exposure and interpretation variability.
• Accurate tooth length measurement is critical for successful endodontic treatment outcomes.

Purpose of the Study:

• To evaluate the accuracy and efficacy of a new instrument, the Apexfinder, for measuring tooth length in endodontics.
• To compare the Apexfinder's performance against conventional radiographic techniques.
• To determine if the Apexfinder offers a simpler and more direct method for tooth length determination.

Main Methods:

• A comparative study involving 142 teeth was conducted.
• The Apexfinder instrument was used for direct tooth length measurement.
• Results were compared with two standard radiographic methods: direct radiography and radiography combined with a tooth-length formula.

Main Results:

• The Apexfinder achieved 90% accuracy in measuring tooth length.
• Conventional radiography yielded 75% accuracy.
• The combination of radiography and tooth-length formula resulted in 60.4% accuracy.
• The Apexfinder demonstrated a statistically significant superiority over radiographic methods.

Conclusions:

• The Apexfinder provides a simple, direct, and accurate method for measuring tooth length in endodontics.
• This new instrument effectively eliminates the need for radiographs, addressing their associated drawbacks.
• The Apexfinder represents a significant advancement in endodontic diagnostic tools, improving procedural accuracy and efficiency.
