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.

D003804	Dentin	The hard portion of the tooth surrounding the pulp, covered by enamel on the crown and cementum on the root, which is harder and denser than bone but softer than enamel, and is thus readily abraded when left unprotected.

D005557	Formaldehyde	A highly reactive aldehyde gas formed by oxidation or incomplete combustion of hydrocarbons. In solution, it has a wide range of uses: in the manufacture of resins and textiles, as a disinfectant, and as a laboratory fixative or preservative. Formaldehyde solution (formalin) is considered a hazardous compound, and its vapor toxic. (From Reynolds, Martindale The Extra Pharmacopoeia, 30th ed, p717)	Formalin,Formol,Methanal,Oxomethane
