Functional tooth unit, periodontal status, and association with weight change in older adults

Journal of Periodontology, EarlyView.
Abstract Background Literature reports that having fewer teeth is associated with reduced chewing capacity, which in turn may lead to weight changes due to diminished oral functionality. This study aims to assess the association between functional tooth units (FTU) and periodontal status and weight change among older adults participating in the Health,

A multicenter, controlled, randomized trial of home‐applied dual‐light photodynamic therapy in stage I to III periodontitis (LumoNorth2022 study)

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis is a widespread, chronic infection‐triggered inflammatory condition in which professional supportive periodontal care (SPC) and daily oral hygiene form the backbone to reduce the disease activity. Light‐based treatments have shown promising antibacterial effects, but their potential for routine home use has not been ...

Consuming heat‐inactivated Lactiplantibacillus pentosus ONRICb0240‐containing postbiotics reduces gingival inflammation: A double‐blind randomized clinical trial

Journal of Periodontology, EarlyView.
Abstract Background Periodontal disease affects people globally, requiring approaches to halt progression at the gingivitis stage. Researchers have investigated live probiotics; we studied the effect of a heat‐inactivated preparation (postbiotic) of Lactiplantibacillus pentosus ONRICb0240 on gingival inflammation.
