Nine commonly encountered subgingival species were enumerated in subgingival plaque samples from periodontally healthy, gingivitis, and adult and juvenile periodontitis subjects employing two elective and three selective media. Samples were also obtained for darkfield microscopy. Results indicated that Eikenella corrodens and Fusobacterium nucleatum were usually elevated in proportions in sites with gingivitis or destructive periodontal disease. Capnocytophaga gingivalis was associated with gingivitis whereas Capnocytophaga ochracea was found in higher proportions in subgingival plaques of subjects with juvenile periodontitis. Previous association of Actinobacillus actinomycetemcomitans with juvenile periodontitis was confirmed. Spirochetes and other motile organisms were found more frequently and in higher proportions in the three disease states and were very strongly correlated with pocket depth. Motile organisms were also positively correlated with levels of plaque and redness in contrast to cocci which showed a strong negative correlation with all clinical parameters recorded.
