An observation of the concentration and type of fluoride compound present in "over-the-counter" adult toothpastes available in Saudi Arabia

Abstract

Objectives: This study was performed to observe the type and level of fluoride compounds existent in 'over-the-counter' (OTC) adult toothpastes available in the open market of Saudi Arabia and to compare them with local and international guidelines. Materials and Methods: More than 100 hyper stores, shops and pharmacies of Dammam and Al Khobar cities were selected randomly and searched for the availability of fluoride containing adult toothpastes. Only toothpastes in which fluoride was present as an active ingredient were included and name of the compound of fluoride and its concentration stated on the packaging of the toothpaste were noted. Results: There were 59 different commercial brands of OTC toothpastes in which sodium fluoride was found in 59.3% of the toothpaste brands (35 of 59), 32.2% of the brands (19 of 59) had sodium monofluorophosphate, 3.3% toothpaste brands (2 of 59) had a combination of sodium fluoride and sodium monofluorophoshpate as an active ingredient, and 5% of the brands (3 of 59) mentioned the fluoride concentration in parts per million (ppm) but did not indicate the type of compound of fluoride present in them. Fluoride concentration found in toothpastes ranged between 1,000-1,470 ppm. Conclusions: Types of fluoride compounds found in toothpastes were consistent with internationally published guidelines. However, majority of toothpastes had 1,450 ppm fluoride which was consistent with Gulf Cooperation Council (GCC) and European guidelines but exceeded the normal range set by United States Food and Drug Administration (US-FDA) and American Dental Association (ADA). Care should be taken when these toothpastes are being used to prevent possible side-effects of fluoride over-exposure.
