The apical patency was verified between each instrument by means of a manual K file (size 10) inserted beyond the apical foramen.
Viewing the base of the blocks, one could see that which would conform to the apical foramen gave an interesting perspective.
The root surfaces of the negative controls were completely coated with two layers of nail varnish, being sure to include the apical foramen, to test the impermeability of nail varnish to methylene blue.
Canal patency was confirmed by inserting a #10 Flex-O File (Dentsply Maillefer, York, PA, USA) to the apical foramen.
All teeth were examined for cracks or fractures, as well as to confirm a single apical foramen using transillumination (Microlux Transilluminator, Adent Inc, Danbury, CT) and a dental operating microscope (Global Surgical Corporation, St Louis, MO).
Khabbaz et al15, did not find any missed canals and reported root canal and apical foramen perforation in 11.
Main advantages of Apex locators are that these measure the root canal length to apical foramen, not to the radiographic apex.
Only single-rooted teeth with a single and round-shaped canal and a single apical foramen were included in the study.
The location of the actual apical foramen in primary teeth, which are in the process of physiological root resorption, poses a great challenge to clinicians [Sim, 2004].
In such cases surgical procedure will simply transfer the apical foramen to a more coronal position, creating an open apex that will predispose to a new or recurrent infection, a periapical lesion, and thus failure.
The main goal of retreatment is to remove all filling material in the root canal and regain access to the apical foramen, (1,2,8-13) thereby enabling the insertion of new endodontic procedures (2,3,7,10) and the subsequent restoration of health of the periapical tissues.
2006d] similarily described how the size of the apical foramen is the strongest healing predictor for the pulp in luxated teeth, while contusion of the apical part of the pulp in mature teeth reduced the chance of revascularisation.
