RESUMO
INTRODUCTION: For a long time researchers have tried to find out a way to grow tissues back to the human body in order to solve transplantation problems by offering the unique opportunity to have their organs back, working properly, in search of life dignity. LITERATURE REVIEW: Stem cells seem to be present in many other tissues than researchers had once thought; and in some specific sites they can be easily collected, without the need of expensive interventions. The oral cavity is one of these regions where their collection can be accomplished, with plenty of accessible sites enriched with these precious cells. AIM: The aim of this literature review is to research where in the mouth can scientists find stem cells to be used in the near future. KEY-MESSAGE: The aim of this literature review is to research where stem cells can be found and collected in the oral cavity.
