What do systematic reviews say?

Full-mouth disinfection (FMD): scaling/root planing (subgingival instrumentation) of all quadrants within 24 hours plus adjunctive antiseptic (chlorhexidine) treatments (rinsing, pocket irrigation, tongue/tonsil brushing) vs Quadrant scaling and root planing (control): SRP of each quadrant in separate sessions at least one week apart

The review found no eligible studies for this question.
