Abstract


Objective: To analyze the formaldehyde content in different brands of formocresol and to evaluate whether there are alterations in the product formula after simulated use and among the brands.
Method: This in vitro study used four commercial brands of formocresol (Biodinâmica®, Iodontec®, Inodon® and Iodontosul®) simulating its clinical use by handling these products daily during 60 days. The chemical analysis was performed at the laboratory of PUCRS’s Chemistry School and focused on formaldehyde, which is formocresol’s main component with significant evaporation property. The analysis comprised three chemical analyses by the gaseous chromatography method.
Results: There was a decrease in the formaldehyde content decreased in the 60-day period for all four brands, suggesting that the product efficiency may decrease with time. It was also observed that the initial formaldehyde content differed among the researched brands.
Conclusion: The efficacy of the product may decrease with time, but the results are not conclusive, needing further research.
