In this study an overview of dental insurance in the Netherlands for periodontal care is presented. Since the dental insurance reform in 1995, dental care is no longer part of the collective health care system. Patients are therefore obliged to enter the market for private dental insurance. Of the 118 available insurance packages 86 (73%) contain dental care. Sixty eight of these packages (58%) include periodontal care. A minority of the companies (4) include periodontal care in all packages. Fifty two percent of the companies apply additional terms, which reduces the scope of the claims. In this paper it is concluded that a sufficient amount and diversity of insurance pachages is present. Since patients may not know about the diversity, insufficient coverage of treatment costs may result. It is concluded that market elements are successful integrated in the field of dental insurance. It has to be shown in the future if this success will lead to an increase of dental and periodontal health of the patients.
