Autologous platelet concentrate (PRP/PRF) in socket vs No blood product (conventional)

Presence of dry socket · Adults with mandibular third molars requiring removal

Autologous platelet concentrate (PRP/PRF) in socket may leads to lower alveolar osteitis compared with no blood product (conventional) (low certainty).

Mechanical (high-volume) irrigation vs Manual (low-volume) irrigation

Presence of dry socket · Adults with mandibular third molars requiring removal

It is very uncertain whether mechanical (high-volume) irrigation changes alveolar osteitis compared with manual (low-volume) irrigation (very low certainty).
