Intraoral dissemination of treponemes after periodontal therapy.
Trial report in Clinical oral investigations, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Oral treponemes are related to chronic periodontitis, but the effect of periodontal therapy on the majority of treponemal species is unknown. The aim of this prospective study was to evaluate the dynamics in prevalence profiles of treponemes in different habitats of the oral cavity. Thirty-five patients with chronic periodontitis were randomly assigned to mechanical debridement alone (control group) or systemic amoxicillin/metronidazole plus chlorhexidine (test group). Subgingival and mucous membrane plaque samples were taken at baseline, after 10 days, and during supportive periodontal therapy at 3, 6, 9, 12, 18, and 24 months. T. denticola, T. lecithinolyticum, T. maltophilum, T. socranskii, T. vincentii, and treponemal phylotypes I-VII were detected using polymerase chain reaction (PCR) and dot blot analysis. For the majority of the assessed treponemes, a significant intragroup increase in prevalence in the different habitats ( P<0.05) occurred over the study course but, compared to debridement alone, adjunctive antimicrobial therapy resulted in a nonsignificant trend toward lower prevalence in the subgingival habitat. In no case were treponemes eradicated from the oral cavity. After both therapies, possibly new infection with and/or dissemination of Treponema ssp. occurred, which led to treponemes recovering in different habitats and to increased intraoral prevalence. The prescribed adjunctive antimicrobial therapy may limit this increase in the subgingival region.
