Surgical removal (extraction) of asymptomatic disease-free impacted wisdom teeth vs Retention (conservative management) of asymptomatic disease-free impacted wisdom teeth

Intercanine width · Adolescents or adults with asymptomatic disease-free impacted wisdom teeth

Surgical removal (extraction) of asymptomatic disease-free impacted… showed no clear difference in intercanine width (dimensional changes in the dental arch) compared with retention (conservative management) of asymptomatic disease-free… (low certainty).

Age 8-10 years vs Age >10 years

Spontaneous space closure · Children and adolescents with maxillary permanent first molar extraction

In the maxilla, age 8-10 years was not associated with a statistically significant difference in space closure odds.

1 finding from 1 review

Mandibular third molar present vs Mandibular third molar absent

Spontaneous space closure · Children and adolescents after extraction of a mandibular permanent first molar (before eruption of the second molar)

In the mandible, presence of the third molar increases odds of spontaneous space closure (OR 2.28; low certainty).

Higher mean patient age (per 1 year) vs Lower mean patient age (per 1-year decrement)

Spontaneous space closure · Children and adolescents after extraction of a mandibular permanent first molar (before eruption of the second molar)

In the mandible, mean patient age was not significantly associated with space closure odds (OR 0.59 per year; not GRADE-rated).

Male sex vs Female sex

Spontaneous space closure · Children and adolescents after extraction of a mandibular permanent first molar (before eruption of the second molar)

In the mandible, sex was not significantly associated with space closure (OR 1.38; not GRADE-rated).

M2 Demirjian stages F-G vs M2 Demirjian stages E-D

Spontaneous space closure · Children and adolescents with maxillary permanent first molar extraction

In the maxilla, M2 Demirjian stages F-G were not associated with a statistically significant difference in space closure odds.

Dental crowding present vs Dental spacing present

Spontaneous space closure · Children and adolescents after extraction of a mandibular permanent first molar (before eruption of the second molar)

One study found space closure more likely with crowding than spacing (OR 5.9; single study; not GRADE-rated).

Second molar at Demirjian stage A-D at extraction vs Second molar at Demirjian stage F-H at extraction

Spontaneous space closure · Children and adolescents with maxillary permanent first molar extraction

In the maxilla, M2 Demirjian stages A-D were not associated with a statistically significant difference in space closure odds.
