Wet-mounts of non-dispersed subgingival microbial specimens from deep pockets of 10 persons with untreated adult periodontitis revealed \"brush formations\" with outer coatings of closely-massed spirochetes exhibiting synchronized motility. Monolayers of closely-packed spirochetes co-aggregated with \"brush formation\" monofilaments were obtained by using mineral oil as a mounting medium for wet-mount preparations. Spirochetes were observed to produce collectively coordinated metachronal wave patterns with their cell movements along the outer surfaces of the \"brush formation\" monofilaments, rather than flexing independently and at random. Organized spirochetal activity in subgingival plaques may serve as a virulence factor contributing to the periodontopathic potential of spirochetes and/or other microbial species.</p>","PeriodicalId":77578,"journal":{"name":"Newsletter (International Academy of Periodontology)","volume":"3 1-4","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4554491/pdf/nihms714483.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33974879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These differences could be due to; composition of plaque, host response or tissue alterations occurring with age. One of the micro-organisms suspected to play a role in the initiation of periodontal disease is the spirochete. A quick and simple way to observe spirochetes is via dark-field microscopy. The present study sample subgingival plaque from the crevices of 6 prepubertal and 6 postpubertal children and observed it under darkfield microscopy. The technique did not involve dispersion. The results showed a higher percentage of spirochetes for the postpubertal group (15.19% in the prepubertal and 21.62% in the postpubertal) but statistical analysis failed to show any significant difference. The small size of the sample, the variety in the technique and the clinical measurements influence the result.</p>","PeriodicalId":77578,"journal":{"name":"Newsletter (International Academy of Periodontology)","volume":"1 2","pages":"6-12"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12973588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
