Routine scale and polish at a fixed interval vs No scheduled scale and polish treatment

Participant satisfaction (perceived oral cleanliness) · Dentate adults without severe periodontitis, regularly attending for dental care in primary care (UK general dental practice)

Planned, regular routine scale and polish (6-monthly; 12-monthly… may leads to higher participant satisfaction (perceived oral cleanliness) compared with no scheduled scale and polish treatment (low certainty).

Autologous platelet concentrates (APC) + open flap debridement (OFD) + bone graft (BG) vs OFD + BG (open flap debridement + bone graft)

Attachment change · Patients affected by infrabony defects requiring surgical treatment, regardless of their age or gender

It is very uncertain whether autologous platelet concentrates (APC) + open flap debridement (OFD)… changes change in clinical attachment level (CAL) (mm) compared with OFD + BG (open flap debridement + bone graft) (very low certainty).
