Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.
Review question

| Comparison | Placebo(s) or blank control(s) (before-after comparisons) | Placebos or blank controls (before-after comparisons) |
| Outcomes | Efficacy on oral microorganisms (>=1 microbial parameter) and/or gingivitis (plaque- and/or gingival inflammation-related index) | Microbial colony counts (Mutans streptococci, Lactobacilli, total bacteria, red-complex bacteria, C. albicans) and gingivitis indexes (Gingival Index, pocket probing depth, plaque indexes, bleeding indexes); 9 studies meta-analyzed for Gingival Index and Plaque Index |
| Study designs | Randomized controlled trials (RCTs) | RCTs (32 included in review; 9 in meta-analysis) |
| Timing | Not specified (outcomes collected at each study's follow-up endpoint) | Most short-term (4 days to 3 months); fluoride mouthwashes longer (6 months, 1 year, or whole orthodontic treatment) |
