Ten studies including both in vivo and ex-vivo designs were included in this review of electronic apex locators. The authors found that precision varied with the device and type of irrigation but was not influenced by the status of the pulp tissue. However, the quality of the included studies was not high with only two being considered to be at low risk of bias.

Electronic apex locators (EALs) have used in permanent teeth since the 1960s and they have been gaining in popularity. The use of EALs in the primary dentitions was proposed in 1996. The aim of this review was to compare the accuracy of EALs in primary teeth when compared to actual root canal lengths (ARCLs). Searches [read the full story…]
When performing root canal treatment determining the position of the apical constriction of the tooth in order to gauge the ‘working length’ of the root canal is an important step. Traditional this has been performed with radiographs although electronic apex locators (EALs) have been available for may years and are becoming increasingly popular. The aim [read the full story…]
