Randomized trial shows improved dental plaque microbiome in adults with periodontitis following therapy, indicating treatment effectiveness.

The study aims to investigate the impact of non-surgical periodontal therapy on the dental plaque microbiome.
Characterized taxonomic composition and functional potential using whole-metagenome shotgun sequencing.
Sampled dental plaque from 39 patients with Stage II or III generalized periodontitis before and 3–4 months after treatment.
Evaluated clinical parameters including probing depth, clinical attachment level, and bleeding on probing.
Periodontal therapy led to a significant reduction in probing depth and clinical attachment level.
Decreased abundance of established periodontal pathogens and increased richness of health-associated early colonizers.
Functional analysis revealed remodeling of carbohydrate-active enzymes with treatment.

Wang et al. (2026) studied this question.
