Fluorosis (percentage prevalence in permanent teeth) · Children exposed to topical fluoride when under 6 years old; fluorosis assessed in permanent teeth at 6 to 18 years

Fluoride varnish applied before 4 years of age may leads to higher fluorosis (percentage prevalence in permanent teeth) compared with no fluoride varnish application (low certainty).

Hydrocortisone plus hyaluronidase (intralesional) vs Placebo or no active treatment

Maximal mouth opening (interincisal distance) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)

It is very uncertain whether hydrocortisone plus hyaluronidase (intralesional) changes maximal mouth opening (interincisal distance) compared with placebo or no active treatment (very low certainty).
