Women who experienced preterm birth vs Women who did not experience preterm birth (term)

Decayed, missing, filled surfaces (DMFS) · pregnant women

Women who experienced preterm birth did not have a significantly different DMFS than those who did not (mean difference -0.15, 95% CI -3.40 to 3.09; 3 studies; I2=89%); certainty of evidence not graded.
