title: The Swedish National Dental Insurance's periodontal diagnosis. Used on an individual level.
abstract: The Swedish National Dental Insurance Board requires a periodontal diagnosis (FKF 2030 86.12GR) from general practitioners before treating patients, a process which is expensive. The Swedish National Dental Insurance-index (SNDI-index) is based on clinical data and radiographs and every tooth is assigned a rating between 0 and 4. From the time of introduction of the Swedish National Dental Insurance plan in 1974, data can have been collected for 1.7 million patients if the regulations were followed according to the Swedish National Dental Insurance Board in Stockholm, Sweden. It is of interest to examine whether all of these collected periodontal data reflect periodontal status. In this study includings 56 individuals, the Swedish National Dental Insurance-index, used on an individual level, correlated significantly with the individual changes in bone support (as percent of toothlength) of the tooth in 1979 (rs = -0.80, t = -9.7, p < 0.001, ci 95% = -0.88(-)-0.68) as well as in 1989 (rs = -0.79, t = -9.5, p < 0.001, ci 95% = -0.87(-)-0.67).
