Research & News
Editor-selected notes on new research, changes to consensus guidance, and interesting studies in periodontology and preventive dentistry.
Research & News is a periodic column from the editorial team. It's not a news feed and it doesn't try to cover every study. Instead, it flags research that changes practical recommendations, updates to consensus guidance, and studies that are being widely covered in a way that might mislead patients.
January 2026 · Editor's note
A short forward-look at three areas where consensus guidance is likely to see revision in the coming year: the classification of peri-implant conditions, host-modulation adjuncts to non-surgical periodontal therapy, and the evolving evidence base for at-home whitening.
December 2025 · Analysis
The CDC's most recent NHANES-derived figures on periodontal disease prevalence held steady, but the demographic and geographic splits deserve more attention than they usually receive. A short read on what stayed the same, what shifted, and what a patient can take from the numbers.
November 2025 · Research note
A pair of small studies looked at whether water flossers meaningfully reduce bleeding in periodontal maintenance patients. Effect sizes were modest and consistent with prior work — useful supplements, not replacements for mechanical contact.
October 2025 · Research note
A revisit of the evidence base for stannous fluoride formulations for gingivitis prevention, with a look at how much of the marketed benefit has held up in independent trials.
Studies covered here are chosen because they either change what a well-informed patient should do, correct something the news cycle has misrepresented, or update long-standing recommendations that appear in our foundational guides. We do not cover every new abstract.
