The aim of this article was to provide an overview of contemporary studies into various types of stem cells derived from oral cavity tissues applied in regenerative dentistry, with particular reference to their function which changes depending on the place of their origin. The growing number of clinical experiments, among which randomised studies conducted on numerous groups of patients are more and more frequent, makes it possible to expect certain therapeutic methods using stem cells of dental origin to be introduced to the standard repertoire of clinical applications in the near future

Key words: mesenchymal stem cells, induced pluripotent stem cells, dentistry, bone regeneration, tissue engineering.
