Abstract
20 patients with juvenile periodontitis (JP) were treated with oral hygiene instruction, scaling and rootplaning, possibly with flap surgery but with no antibiotics. The patients were monitored after 6 to 12 years. Re‐examination revealed that no probing depth of 7 mm or more existed any longer, and that sites with probing depth of 4 to 6 mm had decreased from 237 to 46. The bone loss scores had changed from 18% (range 2.0 to 48.1) to 14% (range 0 to 44.4) and the bleeding on probing scores from 39% (range 0 to 100) to 10% (range 0 to 40). Actinobacillus actinomycetemcomitans (A.a.) had neither been cultivated nor serologically tested at the initial examination. At the re‐examination, it was found in 2 patients out of 20 at 5 sites. 7 patients, the 2 with positive cultures included, had elevated titers to A.a. strain Y4 in whole or parotid saliva or both.It is concluded that there is a marked improvement in the periodontal condition of these patients, and that good periodontal health in patients with JP can be reached without antibiotics.
