Objectives: Probiotic supplementation, integrated into routine oral care, may improve periodontal status and metabolic function. In this retrospective longitudinal study, we evaluated the efficacy of probiotics added to non-surgical periodontal treatment (NSPT) in reducing the burden of oral pathogens and improving metabolic dysfunction. Methods: Twenty outpatients with chronic periodontitis and at least one metabolic abnormality underwent NSPT with daily probiotic supplementation for 12 weeks. Baseline and post-intervention assessments included clinical indices, blood pressure, and blood biomarkers (HbA1c, fasting glucose, and lipid profiles), with analysis of oral pathogens using qPCR. Results: Among the 13 eligible participants, probiotics with NSPT resulted in significant reductions in HbA1c (-0.3%, p<0.001), and systolic blood pressure (-9.6 mmHg, p<0.001), and Tannerella forsythia (p<0.05) levels, along with decreasing trends in other pathogens. However, no significant changes were noted in periodontal indices, including probing pocket depth and bleeding on probing, nor in lipid profiles. Conclusions: These f indings suggest that probiotic supplementation with NSPT may improve glycemic control and systolic blood pressure but may have a limited effect on periodontal indices, warranting larger trials to confirm its potential.
