Low tooth brushing frequency (<2 times/day) vs High tooth brushing frequency (>=2 times/day)
Early childhood caries (ECC) · Healthy children under 6 years of age (6 months to 6 years); preschool children
After excluding an extreme outlier (Alhabdan 2018), the association between low brushing frequency and ECC remained statistically significant (pooled OR approximately 2.0, p=0.003; I2=87.5%); the exact estimate and its CI were not reported; ungraded.
