بررسي تاثير استفاده از دهان شويه سديم بنزوات در كاهش پلاك دندان

Background and Objectives: Sodium Benzoate mouthrinses named Plax have been introduced to the market which claimed that their use before brushing enhances dental plaque reduction through their ability to decrease the adherence of plaque to the teeth. Recently, a similar product has been introduced to the Iranian market. Since studies on Flax have contradictory results and the effectiveness of this type of domestic product has not been investigated adequately, this study was conducted to evaluate the plaque removal effects of this mouthrinse. Materials and Methods: A total of 50 dental students volunteered in this study. The volunteers were prohibited from any plaque control for 36 hours before the study. In the first appointment, after recording of plaque index, brushing was done by the investigator with an identical brush and similar method. In the next appointment procedures were the same as the previous step except for the subjects used for mouthrinse before brushing.The data were analysed by paired comparison t-test. Results: There was no significant difference between mean plaque index reduction with using the mouthrinse (1.47) and not using it (1.44) (p=0.422). Conclusion: with the limits of the present study it can be concluded that a single rinsing with pre-brushing mouthwash may not improve plaque removal efficacy of brushing.
