Question

Do you use electronic apex locators? When? Describe with references the accuracy of these devices.

a) Yes, for determining root canal length
b) Yes, for pulp vitality testing
c) No, I do not use electronic apex locators
d) Yes, for both determining root canal length and pulp vitality testing

Answer 1

Electronic apex locators are used for determining root canal length, not for pulp vitality testing. They are accurate devices that have increased the success rates of root canal treatments.

Step-by-step explanation:

Electronic apex locators are used primarily for determining root canal length during endodontic procedures. They help in locating the position of the apex of the root canal to allow for accurate measurement and subsequent filling. Electronic apex locators are highly accurate, with studies showing an accuracy rate above 90% in locating the apical constriction. These devices have greatly improved the success rate of root canal treatments by minimizing the risk of overfilling or underfilling the canal. It should be noted that electronic apex locators are not designed for pulp vitality testing, which requires different types of diagnostic tools.
