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.
This randomized controlled clinical trial evaluates the effectiveness of a tannic acid-zinc acetate mucoadhesive gel compared to lidocaine gel in reducing gag reflex in children aged 8-10 years during dental procedures. Participants will be randomly assigned to receive either gel applied to the posterior palate before a standardized gag-inducing procedure. The primary outcome is the reduction in gag reflex severity using a validated scoring index. The secondary outcome is the change in pulse rate measured at baseline, after application, and during the procedure. This study aims to assess whether the tested mucoadhesive gel can provide an effective alternative to lidocaine with improved patient comfort.

A mucoadhesive gel containing tannic acid at a specified concentration is applied topically to the oral mucosa prior to the dental procedure. The gel is intended to reduce gag reflex through its astringent and protein-precipitating properties.
A mucoadhesive gel containing zinc acetate at a specified concentration is applied topically to the oral mucosa before the dental procedure. The formulation is used to evaluate its potential effect in reducing gag reflex.
A topical lidocaine gel at an appropriate concentration is applied to the oral mucosa prior to the dental procedure as a standard local anesthetic agent for gag reflex suppression.

Gag reflex severity score using a 5-point Likert faces scale
Gag reflex severity is assessed using a 5-point Likert faces scale (score range: 0-5), where higher scores indicate greater gag reflex severity, following application of the assigned topical gel during the dental procedure.
Time frame: Immediately after gel application during the dental procedure (single visit)
Pulse rate (beats per minute)
Pulse rate is measured using a pulse oximeter and recorded in beats per minute (bpm) to assess physiological response during the dental procedure following application of the assigned topical gel.
Time frame: During the dental procedure (single visit)
