Methods: A village with approximately 2.000 inhabitants at a tea estate on Western Java, Indonesia, was selected. At baseline in 1987 all subjects (N = 255) in the age range 15 - 25 years were examined. The clinical examination included assessment of plaque, bleeding on probing, pocket depth and attachment loss at all interproximal sites. The microbiological examination included evaluation of samples from the tongue, the gingiva, the saliva and the deepest bleeding pocket without attachment loss by means of phase contrast microscopy and immunofluorescence. The clinical examination was repeated in 1994 and 2002. Results: In 2002, 128 subjects could be retrieved. The mean attachment loss increased from 0.33 mm in 1987 to 1.97 mm in 2002. The subjects lost on average at 23 sites ³2 mm attachment. The microbiological examination in 1987 showed a subgingival respectively oral prevalence of A. actinomycetemcomitans 36% and 55%, P. gingivalis 66% and 88%, P. intermedia 81% and 100%, spirochetes 65% and 90% and motile micro-organisms 60% and 100%. Various factors such as age, gender, smoking, plaque, bleeding on probing, pocket depth, attachment loss and the subgingival or oral presence of the putative periodontal pathogens were assessed for the predictive value for future attachment loss. Only 3 variables showed a statistical significant predictive value for future loss: the number of sites with pocket depth ³5 mm, the number of sites with recession and male gender. Conclusions: Screening for interproximal recession and pockets ³5 mm in young adults may be helpful in the early diagnosis and prevention of future progression of periodontitis. | ||
