Evidence Map

What The Sources Report

• We focused exclusively on human clinical trials and in-situ studies performed with humans that provided clinical evidence of efficacy in terms of improving gingival health or reduction of dental biofilms. [Meyer Frederic (2026); evidence level 1]
• The test toothpaste statistically significantly improved clinical signs of gingivitis compared to the active control. [Meyer Frederic (2026); evidence level 1]
• A cross-sectional analysis examining 2725 Chinese men and 3662 women aged ≥65 years found that drinking green tea was associated with reduced tooth loss in men, while black tea was protective in women. [Conde Margaret (2026); evidence level 3]
• Persistent dry mouth increases the risk of poor oral health, including dental caries, periodontal disease, halitosis, candidiasis, and burning mouth syndrome. [Conde Margaret (2026); evidence level 3]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

There is at least one systematic-review style source in the current set, so it deserves more weight than single-study evidence. For green tea oral health randomized trial, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
