Mucoadhesive Gels in Controlling Gag Reflex Among Children During Dental Radiographic Examination
Egypt66 participantsStarted 2026-09-01
Plain-language summary
This randomized clinical trial compares tannic acid-zinc acetate mucoadhesive gel with lidocaine gel for reducing gag reflex in children aged 8-10 years during radiographic dental examination Gag reflex severity and pulse rate will be assessed before and after gel application. The study evaluates the effectiveness of the tested gel as a potential alternative to lidocaine.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* The study will include children aged between 8 and 10 years .
* Pediatric dental patients requiring intraoral radiographs for diagnostic or treatment purposes will be recruited.
* Children present with a fully erupted maxillary last molar to allow standardized placement of the radiographic film for gag reflex stimulation.
* Written informed consent will be obtained from parents or legal guardians before participation.
Exclusion Criteria:
* Children with systemic diseases or neurological disorders that may influence gag reflex,such as epilepsy or cerebral palsy.
* Those with a history of allergies to the materials that will be used in the study gels are not considered eligible.
* Patients with acute respiratory infections, oropharyngeal inflammation, or enlarged tonsils at the time of the examination are excluded to avoid confounding variables.
* Children taking medications known to modify gag reflex or pulse rate, such as sedatives or antihistamines, are not included.
* Uncooperative or extremely anxious children, classified as Frankl ratings 1 or 2, are excluded
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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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.
