Determining Optimal Concentration of Elaegnus Extract on Controling Gag Reflex in Soft Palate and Tonsils

Many dental procedures such as intraoral radiography, impression-taking etc result in gag reflex. Various methods have been proposed for controlling this reflex but no practical and accurate technique has been found to date. The role of Eleagnus extract has been demonstrated in controlling this reflex. The aim of the present study was to evaluate the role of various concentrations of Eleagnus extract on controlling gag reflex. In this clinical trial the effect of 0.5%, 1%, 2%, and 3% aqueous concentrations of Eleagnus extract on gag reflex were evaluated in 168 subjects in 4 groups of 42. The subjects gargled 20 mL of Eleagnus aqueous solution in their mouth for one minute. Gag reflex was checked before and after the use of the solution by means of a tongue blade. The same procedure was repeated for all the concentrations. Data was analyzed by means of Freeman and Wilcoxon statistical tests using SPSS software (α = 0.05). Gag reflex decreased with an increase in Eleagnus concentration (p value < 0.001). Under the limitations of the present study it was concluded that high concentrations of Eleagnus extract are effective in controlling gag reflex.
