Key Points

To evaluate the effects of live and heat-killed Bifidobacterium lactis on periodontal health in a rat model of induced periodontitis.
Administered Bifidobacterium animalis subsp. lactis HN019 and its postbiotic to rats
Induced periodontitis in rat subjects
Measured periodontal health outcomes
Compared effects between live and heat-killed forms.
No significant improvements in periodontal outcomes were observed
Findings suggest limited systemic effects of the tested probiotics and postbiotics

Abstract

Systemic administration of Bifidobacterium animalis subsp. lactis HN019 or its derived postbiotic resulted in no significant improvements in periodontal outcomes in this experimental model. Further investigations using integrative approaches are needed to better characterize the systemic effects of probiotics and postbiotics.
