[Cooperation of the general practitioner with the specialist and the university institute].

When considering the areas in which a periodontist is needed, the degree of collaboration with the general practitioner appears. The various types as well as the level of cooperation are discussed. Moreover, the possibilities and limits of treatment of periodontal disease in the corresponding departments of Swiss Universities are mentioned. Cooperations between practitioner and periodontist or University departments should develop further, provided that the rules of professional ethics are observed.
