For fluoride to be effective in toothpastes, significant amount of fluoride need to be in solution form. Global standard of fluoride content of toothpastes is 1500 ppm (part per million).This study aimed to determine fluoride content of some special toothpastes. Methods This research was cross-sectional and laboratory study. In this study five brands of different toothpastes including: Crest, Sensodyne, Colgate, Unique, Beam were provided and total fluoride of each was determined using ionselection method and then the fluoride content of each brand compared to the global standard amount. The data was analyzed byone sample t-test at 0.05 level of significance. Results Sensodyne had 735 ppm, Beam got 76.12, Colgate got 1195 ppm, Unique got 426 ppm and lastly Crest had 1605.70 amount of fluoride in their composition. Quantitative analysis indicated total fluoride content of Sensodyne, Beam, Unique were significantly below global standard at 0.05 level (p<0.05) in terms of fluoride content whereas total fluoride content of Crest and Colgate had no significant difference with global standard (p<0.05). Conclusion The results showed that Crest and Colgate met the standard of global fluoride content.
