Background and purpose: Dental caries is one of the most common bacterial diseases in childhood. Using proper dentifrice is suggested to reduce the incidence of this disease. The aim of this study was to investigate the antimicrobial effects of different brands of children's dentifrice available in Iran’s market on Streptococcus mutans (PTCC1683) and Lactobacillus acidophilus (PTCC4356) strains. Materials and methods: After culturing standard bacterial strains, different kids dentifrice brands, including Irox, Bath, Misswake, Colgate, Oral-B, Bencer, and Frice were prepared by distilled water in 2 mg/ml and 4 mg/ml and added to pits in cultures medium. Then, the samples were incubated at 37°C for 24-48 hours and diameter of the antibacterial inhibitory haloarchaea was reported in millimeters. T-test was used for statistical analysis. Results: All dentifrices recorded an inhibitory haloarchaea diameter of 3-25 mm (except Bath and Irox at 2 mg/ml against S. mutans, 0 mm). The antibacterial strength of dentifrices was as follows: Oral-B> Colgate> Frice> Bencer> Misswake> Bath> Irox. At 4 mg/ml, the diameter of haloarchaea against L. acidophilus was approximately twice than that of S. mutans. The mean haloarchaea diameter was not significantly different between the control group and dentifrices at 4 mg/ml against S. mutans (P= 0.080). In other conditions, the mean diameter of haloarchaea in dentifrices was lower than that of the control group (P≤0.001). Conclusion: In this in-vitro study, Oral-B and Colgate (sodium fluoride 500 ppm) had the highest antibacterial effect and Bath and Irox (sodium monofluorophosphate 500 ppm) had the lowest antibacterial strength against the studied microorganisms. In addition, except for Bath and Irox, other dentifrices in various concentrations had desirable antibacterial properties.

Background and Aims: The systemic and topical preventive effect of fluoride on tooth decay has been reported. The aim of the present study was to determine the fluoride level in imported and national fluoridated dentifrices in the Iranian market. Materials and Methods: Sampling was randomly performed from the main market centers and pharmacies in Tehran. The total fluoride (TF) and total soluble fluoride (TSF) concentrations were determined by ion specific electrode potentiometer method. The samples were coded and one trained researcher performed the analysis. Descriptive statistics as percentage and analytical statistics reported as independent t-test were reported. Results: In adults’ toothpastes, the total fluoride ranged from 191 to 1601.9 ppm with the mean of 911.2 (SD=331.4) ppm. The total soluble fluoride ranged from 322.8 to 1518.8 ppm with the mean of 1021 (SD=279.8) ppm. In children’s toothpaste total fluoride ranged from 236.3 to 1163.7 ppm and the total fluoride of 594 (SD=375). Total soluble fluoride in children’s toothpaste ranged 655.6-1102.6 with the mean of 879.1 (SD=316.07). Analysis of the total fluoride (TF) and total soluble fluoride (TSF) showed that there was no significant difference between the local and imported toothpastes (P>0.05). Conclusion: The fluoride level of Iranian toothpaste was similar to that of the imported toothpastes, however there was variation in the level of fluoride in products.

Oral hygiene products have been used widely among people since many years ago. Toothpaste and mouthwashes are the main products that are used for health and beauty and the demand for such dental products is high. These products include both chemical and herbal products. Plants form a large part of the surrounding nature, so they are the first choice for health problems. Nevertheless, due to the fast development of chemistry and lack of natural resources herbal products are replaced by chemical compounds. Compared with herbal products, chemical compounds are associated with more side effects, so using herbal drugs are more favorable and researchers are more interested to such products. In oral hygiene drugs the plant extracts affecting inflammation and bleeding are of significant interest to dental professionals. This article introduces one of the most common herbal drugs used as oral care product. [ABSTRACT FROM AUTHOR]
