comparison of the antiplaque effectiveness of meridol [aminefluoride/ stannous fluoride] and irsha kids mouth rinses in 7-9 year-old children

ABSTRACT

Mechanical method of plaque control is still considered the most effective method in reducing microbial dental plaque, however, considering the limitations of this technique in children, the assistance of chemical plaque control methods have been suggested. The purpose of this study was to compare the effects of Meridol and kids Irsha mouth rinses on plaque accumulation in 7-9 year-old school children, referred to Community Dental Health Department of Zahedan Dental School in 2010. A double-blind clinical trial was conducted. Fifty samples were randomly allocated to four groups including Meridol, Kids Irsha, chlorhexidine [positive control] and normal saline [negative control]. Prophylaxis was done for all samples, and plaque index was determined for each sample after 48 hours on days 0 and 30. Samples used mouth rinses every day during this period. The data was analyzed with SPSS-17 using Kruskal-Wallis, Mann-Whitney and Sign tests. In this study, a significance level of p< 0.05 has been considered. At the end of the study, 45 samples attended for plaque index documentation. Plaque index was reduced significantly in all four groups on day 30 compared to day 0. Meridol, Kids Irsha, and saline groups did not show any significant difference with each other with respect to plaque reduction percentage between days 0 and 30, whereas chlorhexidine showed significant difference with Meridol, Kids Irsha and Saline [p=0.001]. The effect of Meridol and Kids Irsha mouth rinses on plaque reduction was not significant compared to that of Chlorhexidin
