Aim:  Dentifrices containing 1,000–1,500 ppm Fluoride have drastically decreased the spread of dental caries. Currently there has been a certain rise in the awareness towards herbal products especially due to the growing awareness towards indigenous medical practices around the world. The use of “herbal” medicine in recent years has gained popularity and led to the growth in health care and its promotion. The aim of the study was to primarily assess presence of fluoride in commercially marketed toothpastes containing indigenous ingredients and to further evaluate the total fluoride (TF) and total soluble fluoride (TSF) levels existing in herbal toothpastes marketed in India.

Materials and Methods: Ten store purchased herbal toothpastes belonging to different companies were obtained. All toothpaste samples were coded. Total bound and soluble Fluoride (F) concentration were determined using the Fluoride ion electrode. The collected data was entered into a datasheet transferred to SPSS software for statistical analysis. Descriptive analysis was done to find the average and standard deviation.

Results: The presence of Fluoride salt being considered, 40% of the dentifrices contained monofluorophosphate as one of the active ingredients and 10 % of them contained sodium fluoride whereas 50% of them were non-fluoridated. Mean TF of the non-Fluoridated toothpastes (B, H, I, G and E) was 648.66 ppm. Fluoridated toothpastes (A, C, D, F, G, I and K) had a mean TF of 981.2 ppm.  Mean TF found in the non-Fluoridated toothpastes (dentifrices B, H, I, G and E) was 601 ppm. Fluoridated toothpastes (A, C, D, F, G, I and K) had a mean TF of 909 ppm.

Conclusion: Upon evaluation we can agree that all toothpastes despite the said claims are found to have moderate levels of fluoride whereas all fluoridated herbal toothpastes have declared optimal levels of fluoride to prevent carious activity. The presence of fluoride in toothpastes that are claimed to be non-fluoridated could be from the presence of the indigenous herbal products added to them. We can conclude that within the given limitations all herbal toothpastes have declared the presence or absence of fluoride.

Clinical significance: Several studies have proved the importance of fluoride in the prevention and arrest of dental caries. With the advent of newer herbal products the necessity to check for the fluoride levels in the herbal ingredients and its interactions becomes essential.
