Association Between Lingual Retraction and Hemodynamic Changes in Patients Receiving Dental Treatment Under General Anesthesia
Turkey (Türkiye)85 participantsStarted 2025-10-13
Plain-language summary
This study aims to investigate the association between sudden decreases in heart rate and blood pressure during dental procedures requiring lingual retraction-such as fillings, root canal treatments, tooth extractions, and cyst surgeries-under general anesthesia. Patients will be routinely monitored for vital parameters during anesthesia. Sudden drops in heart rate and blood pressure (10-20% decrease) will be recorded as lingual retraction-related trigeminocardiac reflex (TCR) events, along with the type of lingual retraction, dental procedure, and tooth location at the time of occurrence. Additionally, the results will be analyzed in relation to patient age, sex, and tongue size.
\*\*Amendment \[March 2026\]:\*\* Following protocol revision and ethics committee approval, the study population has been restricted to pediatric patients (aged 2-18 years), and the adult arm has been discontinued. The primary outcome and observational methodology remain unchanged; however, the secondary outcome regarding adult-pediatric comparison has been removed from the analysis plan.\*\*

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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
