How To Use Your Endodontics Apex Locator Successfully

Posted by webtiger 18/07/2022 0 Comment(s)

Because of the explosive expansion of digitalization in dentistry, the use of digital technology has become not only very common but also absolutely essential in endodontics. The field of dentistry has seen one of the most rapid and significant shifts in its use of technology in the last several decades. During this time span, there has been a significant leap in the advancement of endodontic technology.

 

During root canal treatment, determining the working length of the canal is one of the most important steps (RCT). Canal preparation, which entails removing all soft tissues and bacteria from the root canal, is something that may be done if the working length is accurately determined. 

 

Electronic apex locators come into play at this point, and the successful deployment of these locators reduces the number of radiographs that are required prior to or even during the failure of conventional handling procedures or radiographic techniques. They are also helpful in determining whether or not the root has any perforations or fractures.

 

In Order To Determine The Working Length Accurately, Here Are Some Tips And Tricks:

 

Endodontic treatment has evolved as a result of the development of the Electronic Apex Locator (EAL). Although it has not yet taken the place of imaging-based methods for predicting working length, it does provide an option that is quite accurate for locating the end of the canal.

 

From the very earliest resistance-based devices to the most cutting-edge multi-frequency and impedance-based technology available on the market today, many physicians have been frustrated by readings that are perfect for one minute but then show higher variability for the next minute.


The Following Are Some Suggestions On How To Get The Most Out Of Your EAL In The Least Amount Of Time Possible.

 

1. Using A Dryer To Provide More Precision In The Canal

 

When used in a dry oral environment, the apex finder operates really well. The canal's irrigation and dredging should come before anything else. It is necessary to utilize suction in order to extract the vast majority of the NaOCl, saliva, and water from the oral cavity. It is necessary to properly isolate the tooth that is going to be worked on by using a rubber dam kit or by inserting cotton rolls on the buccal and lingual sides of the tooth. The electrolytic effect of NaOCl coming into touch with metals and restorations on teeth is the source of the majority of problems that arise with first readings. The file has to have a direct route to the dentin, free from interference from any restorations or metal.

 

2. Make the Appropriate Choice of Files

 

The selection of the incorrect file is the second most typical mistake that might occur. It is essential to keep in mind that the functionality of apex locators is dependent on making touch with the walls of the canal. If the file is better tailored to the contours of the canal walls, the reading will be enhanced. The findings will be incorrect if a #10 file is used in the Maxillary central incisor. When the file size approaches that of the foramen's diameter, the accuracy of the measurement improves. As a consequence of this, it is quite important to make use of a file in an effort to get a suitable fit in canals that are broader.

 

3. Utilizing the Electronic Apex Locator in the Correct Manner

 

Put the file clip in the K file where it belongs.

Then, touch both the file clip and the lip hook to see whether the reading comes out to "-3." If it does, this indicates that the apex locator is functioning as it should.

 

Position The Lip Hook So That It Is Touching The Patient's Upper Lip.

 

  • Your apex locator measurements should represent a smooth transition as you approach the peak of the curve as you work toward it. The audio output from the apex finder may also be used to assist in detecting the precise location of the file inside the canal.

 

  • The music becomes louder and more consistent as it approaches the peak, and once it hits the peak, it does not stop (00). If the file is moved even one additional byte farther, an alert will sound, and the display will flash a warning that says "Over Apex" in a red hue.

 

  • No matter what kind of apex locator is used, the reading that is considered to be the most accurate is the one in which the apex locator maintains a steady reading as the file gets closer to the apex. If the display on the apex locator is more "jumpy" or "fluctuates," you may want to try moving to the file with the next greater size.

 

  • When treating an upper molar that has roots that are close to the sinus, the first reading is often the most accurate reading. This is because the apex locator may read a file that is in the sinus.

 

Conclusion

 

When they are used appropriately, endodontic apex locators provide significant time savings and a boost in working efficiency. When the operator is doubtful about the placement of the apex using radiographs alone, such as when the superimposition of the sinus hinders a precise length estimate preoperatively, they may frequently aid pinpoint the location of the apex by providing additional information.
