During the last five years, quality development has become a most important issue in oral health care. In every day practice, quality development meets, however, a considerable number of objective obstacles, mainly due to the lack of direct access to the information necessary in a specific clinical work situation and due to the absence of knowledge on own performance in relation to quality goals. The EU-TAP project ORQUEST has identified different clinical work situations and built up an integrated IT&T-platform composed of different software modules and hardware components for each clinical work situation in order to allow for adequate IT&T-support in specific clinical situations.
