ABSTRACT
Gag reflex is one of the most common problems in dental treatment. All researches performed to reduce or eliminate this reflex were not effective or were time-consuming. The aim of this study was to evaluate the use of Elaeagnus angustifolia lozenge in controlling gag reflex during dental treatment. This study was a randomized double blind controlled trial with convenient sampling on 84 patients that were candidates for radiographic procedures in the School of Dentistry, Isfahan University of Medical Sciences. The cases were randomly divided into two groups of case and control. The case group used Elaeagnus angustifolia L extracts and the control group used placebo. Fruit extract was formed into lozenge. Before and after intervention, the gag reflex was evaluated by stimulation of the soft palate and pharyngeal tonsils. Data analysis and comparison was performed with SPSS 11 software and Chi-square, McNamara and t tests. The gag reflex significantly decreased in the soft palate region [p<0.001] and pharyngeal tonsils [p<0.001] in the intervention group. In the placebo group, decrease of gag reflex was not significant in any of these locations [p=0.9]. The decrease in gag reflex in the soft palate and the pharyngeal tonsils in the case and control groups before and after the intervention showed statistically significant differences [P<0.01]. Elaeagnus angustifolia L. extracts seem to be an effective method to control gag reflex during dental treatment. It may be a confident method to use on dental procedures, especially radiographic procedures

In order to obtain good radiographs having optimum processing solution is important. Generallyafter a period of time the solutions will be oxidized and loose their efficacy. The goal of present research iscomparison of the quality stability of four processing solutions available in market "Champion, Teifsaz, Cronex andNovin".One hundred and twenty eight intraoral radiographic films of one type withspecific speed were exposed under identical exposure factors. A metal step wedge was used for the image.Each 4 days two periapical films were exposed and processed this was continued for two months. Finallyoptical density of radiographs processed in each solution were measured and compared according to the dayof investigation.All of the four solutions created acceptable density on the radiographs on the first day but there was adecrease in optical density after a period of time. Generally the Champion solution made the best density andafter that were Cronex, Teifsaz and Novin. There was a decrease in the quality ofTeifsaz, Cronex, Champion andNovin in order.As the composition and percentage of these four solutions are different, the stability of them arealso different. Champion was found to have the best quality among three other processing solutions
