Root canal treatments are fundamental procedures necessary to preserve a severely damaged tooth. They consist in removing the dental pulp and filling the root canals with gutta-percha.
These procedures were traditionally done using manual files. The dentist would have to measure the root, introduce the file, and manually activate it to prepare the canal. Although this method is effective, it is also time-consuming and can put a lot of stress on the clinician's hand.
Fortunately, the development of contemporary devices led to the creation of the endo motor. This special handpiece can automatically do everything the dentist would require to do manually. Therefore, it reduces the pressure and stress upon the dentist's hand. Additionally, it also makes the procedure easier and faster.
An endo motor is a special handpiece specifically designed for endodontic treatments. This hand-held device can be equipped with dental files to prepare root canals.
They operate through a low-speed motor located inside the handpiece handle. This offers constant torque and speed to safely activate the files inside the root canal with a low risk of accidental instrument fracture.
Endo motor can be wireless or connected to a control box or device. Regardless of the type, their settings can be adjusted freely by the dentist. This allows the clinician to use it appropriately according to the case characteristics.
Endo motors possess a unique rotation system. Unlike a regular handpiece, the endo motor is integrated with an automatic reverse function and is capable of performing a reciprocal rotation.
This allows it to mimic how an endodontic treatment would be performed using manual files.
There are many benefits associated with the replacement of traditional methods with an endo motor, such as:
● වැඩිදියුණු කළ කාර්ය ප්රවාහය:
The endo motor allows the dentist to perform root canal treatments in less time.
● Improved patient comfort:
The patients don't have to spend as much time with their mouths open while the dentist works. This improves their reception toward the treatment and their comfort throughout the procedure considerably.
● Reduced risk of file breakage:
The endo motor offers constant and controlled torque and speed. This reduces the risk of breaking a file inside the root canal.
● Less fatigue:
Since the endo motor does everything automatically, the dentist doesn't have to apply excessive pressure on the hand. This advantage reduces fatigue and stress and lowers the risk of developing health conditions such as carpal tunnel.
Some endo motors can be equipped with an apex locator tip. This helps the dentist to accurately locate the apical foramen location. Furthermore, by having the apex locator integrated into the handpiece, there is no need to invest in a separate device.
