Older age vs Younger adults (population mean age <=33.4 years)

Caries experience (mean DMFT) · Adults aged 19-60 years

Studies of older adults (mean age >33.4 years) had higher pooled DMFT than younger adults, but the age to DMFT meta-regression was not statistically significant; ungraded observational evidence.
