Extraction of a maxillary first permanent molar vs Extraction of a mandibular first permanent molar

Spontaneous space closure · Children aged 5 to 15 years undergoing first permanent molar extraction

Spontaneous post-extraction space closure did not differ significantly between the maxilla and mandible (pooled OR 2.06, 95% CI 0.46 to 9.28; 3 studies; I2 = 72%); ungraded.
