Lingual nerve retractor (subperiosteal or Free's) vs No retractor

Temporary altered tongue, chin, or lip sensation · Adults with mandibular third molars requiring removal

Lingual nerve retractor (subperiosteal or Free's) led to higher temporary altered tongue, chin, or lip sensation compared with no retractor; GRADE not reported.

Absence (previous removal or agenesis) of asymptomatic disease-free impacted wisdom teeth vs Retention (conservative management) of asymptomatic disease-free impacted wisdom teeth

Caries affecting the (distal) adjacent second molar · Adults (416 healthy male volunteers aged 24 to 84 years) with asymptomatic disease-free impacted wisdom teeth

It is very uncertain whether absence (previous removal or agenesis) of asymptomatic disease-free… changes caries affecting the (distal) adjacent second molar compared with presence (retention) of asymptomatic disease-free impacted wisdom… (very low certainty).

Primary (complete) wound closure vs Secondary (partial) wound closure

Adverse effects (reactionary bleeding) · Adults with mandibular third molars requiring removal

It is very uncertain whether primary (complete) wound closure changes adverse effects (reactionary bleeding) compared with secondary (partial) wound closure (very low certainty).
