Comparison of Accuracy in Determining the Root Canal Working Length by Using Two Generations of Apex Locators - An In Vitro Study.

Aim: The present in-vitro study aims to compare the accuracy of root canal working length determination between the third generation and fourth generation electronic apex locators.

Material And Methods: Fifty extracted single-rooted single canal teeth were selected for the study, and a definite coronal plane was prepared. Actual working length (AL) was measured using a stereomicroscope under 8X magnification.

Paralleling technique for frenectomy and oral hygiene evaluation after frenectomy.

Background: High frenum attachment is a very common problem in the population. Various conventional techniques are available which has certain disadvantages; in addition to that high frenum also hinders oral hygiene maintenance. This study aims to evaluate patient's response to two different frenectomy technique, and oral hygiene maintenance before and after frenectomy.
