Subperiosteal prepared (SPP) wound closure after tooth extraction vs Epiperiosteal prepared (EPP) wound closure after tooth extraction

MRONJ after tooth extraction (incidence proportion) · People on antiresorptive treatment undergoing tooth extraction (at risk of MRONJ)

Subperiosteal prepared (SPP) wound closure after tooth extraction showed no clear difference in MRONJ after tooth extraction (incidence proportion) compared with epiperiosteal prepared (EPP) wound closure after tooth extraction (low certainty).

Extraction of the mandibular permanent first molar vs Not applicable (single-group prevalence)

Rotation of the mandibular second premolar · Children and adolescents after extraction of a mandibular permanent first molar (before eruption of the second molar)

After mandibular first molar extraction, the second premolar was rotated in about 60% of cases (2 studies; very imprecise; not GRADE-rated).
