Battery Saving Feature

Battery life is a critical aspect, especially for busy dental practices. A dental apex locator with an efficient battery-saving feature will extend the device's operating time, minimizing the need for frequent recharging or battery replacements. The digital apex locator also can turn it off after a short period of inactivity, so as to save the battery energy.

By the way, a battery-saving dental apex locator can effectively prevent the device from running out of power during the surgery process.

Durability and Safety

Durability and safety are important factors in the endodontic apex locator. A poor-quality and unsafe dental apex locator may violate the health of the patient and the dentist. Therefore, it is necessary to check the durability and safety of the apex locator. You need to choose the best apex locator which is made of high-quality materials and has good safety design to endure the rigors of the dental clinic environment.

Size of the Device

The size of the device also is another important factor. The size of the device almost determines the portability of the dental apex locator. Therefore, if you emphasize the portability of the device, you need to pay more attention to the size of the device. An endodontic apex locator with good size not only saves space in your delivery tray but also can be moved around easily for working in different quadrants of the oral cavity.

Which Size of File is the Best with an Apex Locator?

For initial canal negotiation and cleaning, smaller file sizes (e.g., sizes 10 to 15) are typically used to gently explore the canal and remove debris. As the procedure progresses and the canal is prepared for shaping, larger file sizes (e.g., sizes 20 to 40) may be employed. In general, the best file size to use with an apex locator file holder is the one that matches the root canal's anatomy and provides accurate measurements of the working length.
