The increase of formaldehyde level in some rare pathological cases of teeth determined with the use of quantitative...

In our previous works we proved that formaldehyde (HCHO) level in hard tissues of teeth could depend on their physiological state. In the current paper we presented the results of HCHO determinations in different dental pathologies, mainly the ones rarely encountered in dental practice, e.g. in the case of reinclusion. The determination of HCHO in the form of dimedone was performed by means of quantitative TLC. The obtained results were compared with HCHO levels in hard tissues of teeth presenting pathological changes. It proved that the highest HCHO level was found in reincluded teeth while it was lower in retained teeth, that is the ones which are not subjected to stress factors present in the mouth. The obtained results can constitute a contribution to the problems of dental pathologies, mainly caries which is a very common problem.
