Comparison of the efficacy of two toothpastes (Darougar and Kam) and Colgate in amount of plaque in children

Microbial plaque is an important factor in occurrence of oral and dental disease and prevention of plaque formation is important. Use of toothpastes with antimicrobial effects is prominent. Sodium lauryl sulfate is one of the anti microbial agents used in toothpastes. That was claimed to be effective in prevention of plaque formation. Due to controversies about SLS effectiveness and in order to failures of previous studies, especially in the field of pediatric dentistry, the aim of this study was to compare the effect of two Iranian toothpaste (darugar/ kam) with a standard foreign toothpaste (Colgate) on plaque control.This clinical randomized double blind cross over study was done on48 cases of 6- 7 year old female pediatric patients. It was performed in 4 stages by use of 4 chemical products (water, Kam, Darugar and Colgate). Initial plaque levels were determined using disclosing tablet, then turns to zero by standard procedure. The patients were followed regularly and plaque indices were registered after 96 hour tooth brushing with products as the only form of oral hygiene, plaque indices were measured and recorded again. Nor the samples neither the examiners were aware of toothpastes type and groups. Data were analyzed using Repeated Measure ANOVAs test. Plaque index was reduced after using Darugar and Colgate toothpastes (p.value:o.008),that was significant. But after using Kam toothpaste and water, plaque index do not have any significant changes. (p.value:o.252) The amount of plaque reduction using Darugar toothpaste was little more than Colgate, but it was not statistically significant.Darugar and Colgate toohpastes were effective in plaque control. Darugar showed more reduction in plaque index, but the difference was not significant. After using Kam and water,the plaque indices did notshow significant changes,so it seems that Darugar and Colgate toothpastes are more effective for plaque control.
