Chlorhexidine mouthwash vs Blank control: Total bacteria (colony count)

Population
Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)
Intervention
Chlorhexidine mouthwash
Comparison
Blank control
Outcome
Total bacteria (colony count)

Chlorhexidine mouthwash may reduce total bacteria colony counts versus blank control in the short term, but the evidence is very uncertain (very low certainty).

How reviews are matched to this question

Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
