Definition of the problem Every extracted tooth is primarily the private property of the patient concerned. It is subject to his or her autonomy-based right to self-determination. This largely undisputed fact contrasts with the practical need for extracted teeth for research and teaching. Thus, testing new materials and techniques for root canal fillings is inconceivable without the use of extracted teeth, as is the practical dental (endodontic, tooth preserving or prosthetic) education of future dentists as part of their university studies. Recently, there has been an increase in criticism of the conventional practice of acquisition and use of extracted teeth. Therefore, the present article is devoted to the question of how the ethical and legal conditions for the use of extracted teeth can be reconciled with the requirements of teaching and research. Arguments Related to this are the questions of (1) the indication for extraction, (2) the risk of commercialization and external pressure, (3) the appropriate time frame for informing the patient, (4) the extent of the duty to inform the patient and (5) the manner and the extent of the documentation. The article presented consists of an ethical and legal analysis of the problem areas mentioned above, taking into account the relevant legislation and available literature. Conclusion The study leads to the conclusion that the recruitment and the use of extracted teeth are ethically and legally permissible under certain clearly defined conditions.
