Summary
The Root ZX II electronic apex locator (EAL) accurately determined root canal working length in 70% of primary teeth. This device offers a reliable method for endodontic procedures in primary dentition.
Area of Science:
- Pediatric Dentistry
- Endodontics
- Dental Technology
Background:
- Accurate root canal working length determination is crucial in pediatric endodontics.
- Traditional methods can be challenging in primary teeth due to anatomical variations.
Purpose of the Study:
- To assess the accuracy of the Root ZX II electronic apex locator (EAL) for determining root canal working length in primary maxillary incisors.
Main Methods:
- The Root ZX II EAL was used to measure working length in 40 primary maxillary incisors.
- Digital radiography was employed to verify the EAL measurements.
- Teeth were categorized based on file tip proximity to the radiographic apex.
Main Results:
- The Root ZX II EAL demonstrated 70% accuracy (28/40 teeth) within 1mm of the radiographic apex.
- Inaccurate measurements occurred in 25% (short) and 5% (long) of cases.
- A high positive correlation (r = +0.82) was found between EAL and radiographic measurements.
Conclusions:
- The Root ZX II EAL is a reliable device for root canal length determination in primary maxillary incisor teeth.
- Its use can enhance the precision of endodontic treatment in pediatric patients.

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.

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.

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
