Non-Surgical Periodontal Therapy Modulates Oral Microbiome in Primary Immunodeficient Children.
Article in Journal of clinical periodontology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
aimPrimary Immunodeficiencies (PIDs) arise from rare genetic defects affecting humoral and cellular immunity, which can lead to reduced dental plaque control. This study aimed to characterise the subgingival dental plaque microbiome in neutropenic PID children compared to healthy controls and assess their response to non-surgical periodontal therapy.
methodsSubgingival plaque was collected from three first molars and one first incisor at baseline and 6 months post therapy from children with PID (n = 24) and systematically healthy control participants (n = 24) who were recruited from Great Ormond Street Hospital and Barts Health NHS Trust, respectively. The subgingival microbiome was profiled using an Illumina metabarcoding approach on the bacterial 16S rRNA gene V1-V2 region.
resultsSignificant shifts in community structure were observed post therapy, as measured by alpha and beta diversities. An increase in Rothia spp., Neisseria spp. and Actinomyces spp. was noted in PID children post therapy, consistent with clinical improvements. Baseline blood absolute neutrophil counts in PID children were positively associated with Streptococcus cristatus and Gemella spp., and negatively with Saccharibacteria, Capnocytophaga and Porphyromonas spp., highlighting key host-microbial relationships.
conclusionNon-surgical periodontal therapy modulated the subgingival microbiota in neutropenic PID children, revealing novel host-microbial interactions important for the oral microbiome in health.
