    Background And Aims
    The main necessity of planning for dental health promotion and preventive training intervention is the continuous monitoring. The current study has been designed for evaluation of dental hygiene condition of a sample of 12 year old students in Isfahan.
    Materials And Methods
    this cross-sectional study included 300 students with the age of 12 who were chosen by cluster sampling. A dentist gathered the information via examination and then the diagnosis of dental decay and dental hygiene condition (based on the suggested method by WHO) and calculation of DMFT and OHI-s indexes in the students were performed.
    Results
    132 individuals (44%) of 300 students were girls. Average of DMFT and OHI-s among students was 4.016± 2.376 and 1.284± 0.465 respectively. There was no significant difference of DMFT between girls and boys (P= 0.891). The OHI-s was significantly higher in boys than girls (P = 0.028). The levels of good and intermediate conditions of OHI-s based on the OHI-s classification were determined in 45.4% and 54.6% of girls and 33.9% and 66.1% of the boys respectively.(P = 0.028)
    Conclusion
    Dental and oral hygiene condition of Isfahanian students is at the intermediate level. These results are representative of a serious requirement for planning and programming to survive of intact, filled and decayed teeth.

    Background and Aim
    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.
    Materials And Methods
    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.
    Result
    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.
    Conclusion
    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.
