Effect of Manual and Mechanical Glide Path Preparation on Working Length Accuracy.
60 participantsStarted 2026-06-04
Plain-language summary
Accurate working length determination is essential for successful root canal treatment and is influenced by proper glide path preparation. This in vitro study aims to compare the accuracy of working length achievement following manual and mechanical glide path preparation techniques. Sixty extracted single-rooted permanent teeth will be randomly allocated into two groups. Group 1 will undergo manual glide path preparation using stainless steel K-files, while Group 2 will receive mechanical glide path preparation using rotary PathFile instruments. Initial and final working lengths will be measured using an electronic apex locator and confirmed with digital radiographs. The difference between the initial and final working lengths will be analyzed statistically. The results of this study will help identify the more effective glide path preparation technique for maintaining working length accuracy and improving endodontic treatment outcomes.

Exclusion Criteria:
Teeth with caries, fractures, cracks, or root defects. Teeth with previous endodontic treatment. Teeth showing root resorption or calcified canals. Teeth with unusual root canal anatomy or multiple canals. Teeth with severe canal curvature greater than 15 degrees. Teeth with immature apices or open apices.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
