Mini apex locator

Jul 25,2025

The mini root canal length measuring instrument uses electronic apex location technology, and its working principle is based on the change of conductivity in the root canal. When a small measuring probe is inserted into the root canal and contacts the periapical tissue, the instrument can capture this subtle difference due to the different electrical resistance characteristics of the periapical tissue and the liquid in the root canal, and automatically calculate the working length of the root canal. This process does not require X-ray irradiation, greatly reducing the patient's radiation exposure.

Hello everyone, I'm Jacky from Foshan Liangya Dental Equipment, and today I'd like to introduce a mini root canal length measuring instrument.

In the field of dentistry, root canal treatment, as an important means of preserving severely damaged or infected teeth, has always been a focus of attention for clinicians in terms of accuracy and safety. In traditional root canal treatment, determining the root canal working length is one of the key steps, which directly affects the success of the treatment and the patient's long-term prognosis. In recent years, with the advancement of technology, an innovative tool called the "mini root canal length measuring instrument" has emerged, bringing revolutionary changes to root canal treatment.

Mini Root Canal Length Measuring Instrument

The core of root canal treatment lies in thoroughly removing the infected material from the root canal and sealing it with appropriate filling material to prevent reinfection. However, due to the complexity of the root canal system, especially the multi-rooted structure of posterior teeth, accurate measurement of the root canal length is a major challenge. Traditional measurement methods include X-ray film methods and tactile methods, but these methods have limitations such as insufficient accuracy, radiation exposure, or dependence on the doctor's experience.

Working Principle and Technical Characteristics of the Mini Root Canal Length Measuring Instrument

The mini root canal length measuring instrument uses electronic apex location technology, and its working principle is based on changes in the electrical conductivity within the root canal. When a small measuring probe is inserted into the root canal and contacts the periapical tissue, the instrument can capture this subtle difference and automatically calculate the working length of the root canal because the electrical resistance characteristics of the periapical tissue are different from those of the liquid in the root canal. This process does not require X-ray irradiation, greatly reducing the patient's radiation exposure.

The mini root canal length measuring instrument uses a new type-C interface, making it more convenient to use and enabling faster and more accurate data transmission.
