Summary
A new tactile method accurately determines root canal length in teeth with open apices. This technique shows high precision and repeatability for endodontic procedures.
Area of Science:
- Endodontics
- Dental Anatomy
Background:
- Accurate working length determination is crucial in endodontic treatment.
- Teeth with open apices present unique challenges for conventional methods.
Purpose of the Study:
- To introduce and evaluate a novel tactile method for working length determination.
- To assess the accuracy and repeatability of this tactile method in teeth with open apices.
Main Methods:
- Ninety teeth with 129 root canals had apices prepared to be open.
- A tactile method using a K-file bent at the tip was employed for measurement.
- Two operators repeated measurements, and results were compared to the correct working length (CWL).
Main Results:
- 97% of tactile working length (TWL) measurements were within 0.5 mm of the CWL.
- The mean absolute difference between TWL and CWL was 0.1 mm.
- High repeatability and inter-operator agreement were observed.
Conclusions:
- The tactile method offers a potentially accurate and reliable approach for working length determination.
- This technique is a viable option for managing teeth with open apices in endodontics.

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
