Abstract

OLIVEIRA, Letícia Selbach de; ROSSATO, Luciana Grazziotin  and  BERTOL, Charise Dallazem. Microbiological contamination evaluation of different dentrifices. Rev. odontol. UNESP [online]. 2016, vol.45, n.2, pp.85-89.  Epub Jan 26, 2016. ISSN 1807-2577.  https://doi.org/10.1590/1807-2577.10315.

Introduction

Microbiological evaluation in personal care products is important to guarantee user safety and product quality since microbial contamination elicits health problems especially in immunocompromised patients.

Objective

To verify the compliance with the requirements regarding the microbiological quality of creams and dental gels acquired commercially.

Material and method

Microbiological contamination was performed through total bacterial and fungal viable count and research of E. coli, Salmonella sp., S. aureus and P. aeruginosa in twenty-one samples.

Result

52.0% of sample presented microbial growth, and 28.6% and 0.21% presented fungal and bacterial contamination, respectively, exceeding the limits described in Brazilian Pharmacopoeia for topical preparations (maximum allowable 2 × 102 CFU / g of bacteria and 2 × 101 CFU / g yeast). None of the researched pathogens E. coli, Salmonella sp., S. aureus and P. aeruginosa were found.

Conclusion

These results indicate that many products available in the market present inadequate quality, demonstrating quality control failures. Rigorous inspection and adoption of regulatory and educational measures aligned with the compliance of Good Manufacturing Practices by manufactures are needed to prevent this situation.

Keywords : Microbiological contamination; quality control; toothpastes; dental gels.
