Chlorhexidine mouthwash vs placebo

Plaque index (PI) / oral hygiene · People undergoing orthodontic treatment (any age; 9 to 34 years in included studies)

Chlorhexidine mouthwash reduced Plaque Index versus placebo, but certainty is very low.

Chlorhexidine 0.2% vs Pre-treatment (baseline, same group)

Plaque · Medically healthy individuals (adults and children, 6-60 years)

0.2% chlorhexidine rinse reduced plaque relative to baseline; not GRADE-rated.

Chlorhexidine 0.12% mouthrinse vs Pre-treatment (baseline, same group)

Plaque · Medically healthy individuals (adults and children, 6-60 years)

0.12% chlorhexidine rinse reduced plaque relative to baseline; not GRADE-rated.

Chlorhexidine solution enclosed in implant inner part vs Normal saline

Plaque · Adults with dental implants and healthy peri-implant soft tissues at baseline

Chlorhexidine solution enclosed in implant inner part showed no clear difference in plaque compared with physiologic (saline) solution; GRADE not reported.

Chlorhexidine mouthrinse (any concentration; 0.05% to 0.2%) used in conjunction with mechanical oral hygiene procedures vs Placebo/control mouthrinse, or no mouthrinse (mechanical oral hygiene alone); controls pooled (protocol's separate comparisons versus mechanical oral hygiene alone and versus placebo/control merged)

Plaque · Children or adults with gingivitis or periodontitis capable of performing normal mechanical oral hygiene procedures (some with medical…

Chlorhexidine mouthrinse (any concentration; 0.05% to 0.2%) used in… leads to lower dental plaque (various plaque indices) compared with placebo/control mouthrinse, or no mouthrinse (mechanical oral… (high certainty).

Chlorhexidine mouthwash vs Blank control

Plaque · Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)

Chlorhexidine mouthwash may reduce the Plaque Index versus blank control in the short term (WMD -0.70, 95% CI -1.12 to -0.27), but the evidence is very uncertain (very low certainty).

Mechanical debridement plus topical minocycline vs Mechanical debridement plus chlorhexidine gel

Plaque · Adults with dental implants and peri-implant mucositis at baseline

Mechanical debridement plus topical minocycline showed no clear difference in plaque compared with mechanical debridement plus chlorhexidine gel; GRADE not reported.

Hyaluronic acid gel (brushing) vs Chlorhexidine, 0.2% to 2% (solution or gel)

Plaque · Adults with dental implants and healthy peri-implant soft tissues at baseline

Hyaluronic acid gel (brushing) showed no clear difference in plaque compared with chlorhexidine gel (brushing); GRADE not reported.

Salvadora persica (miswak) mouthrinse vs Chlorhexidine mouthrinse

Plaque · Medically healthy individuals (adults and children, 6-60 years)

When usual mechanical plaque control continued, Salvadora persica and chlorhexidine did not differ significantly for plaque; not GRADE-rated.

Salvadora persica (miswak) mouthrinse vs Chlorhexidine 0.2% mouthrinse

Plaque · Medically healthy individuals (adults and children, 6-60 years)

Salvadora persica was less effective than 0.2% chlorhexidine at reducing plaque (favours chlorhexidine); not GRADE-rated.

Salvadora persica (miswak) mouthrinse vs Placebo rinse

Plaque · Medically healthy individuals (adults and children, 6-60 years)

Salvadora persica rinse reduced plaque more than placebo (favours Salvadora persica); certainty not GRADE-rated (Shekelle grade Ia).

Salvadora persica (miswak) mouthrinse vs Pre-treatment (baseline, same group)

Plaque · Medically healthy individuals (adults and children, 6-60 years)

Salvadora persica rinse reduced plaque relative to its own baseline; not GRADE-rated.
