Dental fluorosis of aesthetic concern (Dean's Index, TFI, TSIF) · Populations of all ages (mostly children) exposed to drinking water with differing fluoride concentrations
Higher water fluoride concentration (fluoridated water; natural or… may leads to higher dental fluorosis of aesthetic concern (Dean's Index, TFI, TSIF) compared with lower water fluoride concentration (concurrent control) (low certainty).

One study (252 children) compared xylitol (7.5 g/day) candy with control (sorbitol) candy over 36 months. The data could not be used in analysis because the authors combined primary/deciduous and permanent teeth and…

Number of infants with a caries increment (dmfs) · Infants (primary teeth)
It is very uncertain whether xylitol tablets (200 to 600 mg/day) via slow-release pacifier/dummy changes number of infants with a caries increment (dmfs) compared with control (sorbitol) tablets (very low certainty).

Caries increment in permanent teeth · Children aged about 12 to 16 years (Hardwick 1982), community setting
Initiation of water fluoridation (artificial or natural) led to lower caries in permanent teeth (change in DMFS) compared with low/non-fluoridated water (0.4 ppm fluoride or less); GRADE not reported.
