Quantitative TLC determination of formaldehyde in hard tissues of teeth

Levels of formaldehyde, which is formed within cells as an indispensable part of biological processes, have been determined by means of TLC in hard tissues of human teeth, with and without pathological changes. A wide variety of formaldehyde levels was determined according to the physiological state of a tooth. The results show that caries can be of immense importance in the process of formaldehyde formation and its release in hard tissues of human teeth.
