Abstract

Clinical, microbiological and immunological factors were examined using data from a subject with periodontosis. The subject was monitored at bimonthly intervals for 26 months at 6 sites per tooth for redness, plaque, suppuration, bleeding on probing, pocket depth, and attachment level. Using attachment level measurements and the tolerance method of analysis, sites with active disease and control (inactive) sites of equal pocket depth were selected. Subgingival plaque samples were taken from these sites for predominant cultivable and dark field evaluation before, and 5 and 13 months after treatment by Widman flap surgery and systemic tetracycline. 50 isolates from each of 5 sites monitored before and after treatment were characterized and, if possible, identified. Active sites showed between 2 and 6 mm of attachment loss prior to therapy and "gained" between 2 and 9 mm of attachment after therapy. The control sites "gained" 0 to 1 mm of attachment after therapy. Bleeding on probing was significantly reduced after treatment, whereas plaque accumulation increased significantly in the sampled sites. Similar changes were seen in the remaining sites. The proportions of Actinobacillus actinomycetemcomitans and Selenomonas sputigena were elevated in active sites, while proportions of Bacteroides intermedius were elevated in control sites. 5 months after treatment, proportions of A. actinomycetemcomitans, S. sputigena and Eikenella corrodens were significantly decreased in the previously active sites and proportions of B. intermedius and E. corrodens were significantly decreased in the control sites. 13 months after therapy, the proportions of Fusobacterium nucleatum and Capnocytophaga species had increased. Multiple linear regression analysis was used to examine models which could "predict" the outcome, attachment level change in the previous monitoring period. The proportions of A. actinomycetemcomitans and S. sputigena, which were associated with destruction, coupled with the proportions of Streptococcus sanguis II and Campylobacter concisus which were associated with "gain" could predict prior attachment level change with an r2 of 0.93. Humoral antibody response to A. actinomycetemcomitans and C. sputigena significantly increased in a period in which multiple actively breaking down sites were detected. Antibody responses to 20 other species tested did not significantly change during the course of monitoring. Crevicular fluid and tissue levels of antibody to A. actinomycetemcomitans were elevated in 5 of 6 active destructive lesions prior to therapy.(ABSTRACT TRUNCATED AT 400 WORDS)
