Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests three gels applied to the mouth before dental X-rays to see which best controls the gag reflex in children aged 8-10. The gels include tannic acid-zinc acetate, lidocaine, and a placebo. Researchers will measure gag severity and pulse rate in 66 children to find a better alternative to standard numbing gels.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
tannic acid-zinc acetate mucoadhesive gel
What this could lead to
If it works, this could offer a simple, non-numbing alternative to lidocaine for controlling gag reflex in children during dental X-rays.
What could go wrong
This is a small pilot study with only 66 children, so results may not apply to everyone. The gels may not work better than lidocaine or could cause side effects.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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
