Chronic periodontitis


The purpose of this study was to assess the long-term influence of gingival inflammation on tooth loss.

The data originated from a 26-year longitudinal study of Norwegian males, who practiced adequate daily oral home care and received "state-of-the-art" dental care. The initial examination in1969 included 565 individuals aged between 16 and 34 years. Subsequent examinations took place in 1971, 1973, 1975, 1981, 1988 and 1995. Thus, the study covers the age range of 16–59 years. At baseline (1969), out of possible 15,820 teeth (565 × 28), 15,383 teeth were present.

Four hundred and thirty-seven teeth had already been missing for unknown reasons. Teeth with Severity Group yielded an odds ratio for tooth loss that was 46 times higher Teeth surrounded with inflammation-free gingival tissues were maintained for a tooth age of 51 years, while teeth consistently surrounded with inflamed gingivae yielded a 46-times higher risk to be lost.

Only two-thirds of such teeth were maintained throughout the 26-year observation period. This documents the role of gingival inflammation as a risk factor for future tooth loss.
