ABSTRACT
This study aimed to assess the quality of locally manufactured toothpastes available in Nigerian markets by evaluating various physicochemical parameters and key components. Samples of four popular toothpaste brands (Colgate, Oral-B, Closeup, Pepsodent) were collected based on demand and consumption rates. The samples were carefully scrutinized for expiry and transported to the laboratory for analysis. Titanum dioxide, Saccharin, and Flouride contents were determined using UV-Vis spectroscopy, while the heavy metals (Pb, Cu, Cd) were done with Atomic Absorption Spectroscopy (AAS). PH meter (pocket pro pH tester pHEP4) was used to measure the pH of the samples. The results revealed significant variations among the toothpaste brands in terms of fluoride concentration, saccharin levels, titanium dioxide content, moisture content, pH, and trace metal concentrations. For instance, Colgate exhibited a fluoride concentration of 1420 ppm, Closeup had a saccharin level of 15000 ppm, and Pepsodent showed a titanium dioxide content of 5400 ppm. Comparison between the fluoride levels obtained in this study and regulatory standards highlighted the importance of consistent product characterization for consumer health and awareness. In conclusion, this study provides valuable insights into the quality assessment of toothpaste brands available in Nigerian markets, emphasizing the need for continuous monitoring and adherence to regulatory standards for dental care products.
