Abstract:

Iron deficiency anemia in children is commonly managed with oral iron supplements, but liquid formulations are often associated with undesirable tooth staining. This in vitro study evaluated enamel discoloration on primary teeth after exposure to ferrous sulfate and iron polymaltose complex. Sixty extracted primary anterior teeth were divided into three groups and immersed daily for 21 days; with color change measured using a spectrophotometer and stereomicroscopy. Ferrous sulfate caused the highest degree of staining (ΔE = 12.6), followed by iron polymaltose (ΔE = 6.3), while controls showed minimal change (ΔE = 1.2). Ferrous sulfate was associated with significantly greater enamel staining, highlighting the need to prefer low-staining formulations to improve pediatric compliance and aesthetics.

Effects of EDTA on End-Point Detection Methods

Effects of EDTA on End-Point Detection Methods

Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
