Stem cells have been the main object of study in the Restorative Medicine scientific field. When obtained from embryos, such cells may distinguish in all tissues, although the methods applied to obtain them have to deal with ethical and legal dilemmas. In the search for alternative sources of stem cells, teeth have gained relevant ground. Those organs present, in their pulp tissue and neighboring structures, fundamental characteristics, such as multilineage differentiation and capacity for self-renewing, besides the fact that they are easy to access and obtain. This work provides the current knowledge and perspectives about the application of stem cells from dental source, with emphasizing those obtained from exfoliated deciduous teeth. Especial attention has been drawn to legal and administrative constraints found in the activities of Human Teeth Banks and Biobanks in Brazil, an aspect that has risen as the main obstacles when communicating the use of stem cells from dental source.

Keywords : stem cells; biorepositories; biobanks; bioethics.
