Replacement of the defective restoration vs Repair of the defective restoration

Composite: Preference for replacement over repair - Scenario 6: superficial discoloration · Dentists managing a defective direct resin composite restoration (posterior occlusal Class I; standardized vignette of a 30-year-old,…

For a defective composite restoration with superficial discoloration, surveyed dentists most often preferred repair over replacement (pooled RR 0.28; p < 0.001); ungraded.

Dental caries vs Caries-free controls

Periodontitis (prevalence) · adults

Using adjusted ORs, caries remained associated with higher periodontitis odds (OR 1.57).

Overweight/obesity (combined) vs Normal Weight or Non‐Obese

Dental caries prevalence · Brazilian children/adolescents in permanent dentition (BMI classified by CDC 2000 growth charts)

The evidence is very uncertain about the effect of overweight/obesity on caries odds in the permanent dentition (very low certainty).

Periodontitis vs No periodontitis (periodontal health or gingivitis)

Dental caries prevalence · adults

With a non-standard periodontitis definition, the association persisted (OR 1.38).

Ate or licked fluoride toothpaste vs Did not eat or lick fluoride toothpaste

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
1 finding from 1 review
  • Topical fluoride as a cause of dental fluorosis in children 2024 · Cochrane All outcomes
    Fluorosis assessed when most permanent teeth of interest had erupted (6 to 18 years)
    Nine studies investigated whether children ate or licked toothpaste; measurement subjective so not meta-analyzed (Table 1). Findings mixed: some studies found no significant difference; others (e.g. Celeste 2016 OR up…

Brushed less than once per day vs Brushed once or more per day

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

Brushed less than once per day may leads to lower fluorosis (percentage prevalence in permanent teeth) compared with brushed once or more per day (low certainty).

Fluoride varnish applied before 4 years of age vs Non-fluoride (placebo) varnish

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 (biannual) showed no clear difference in fluorosis (percentage prevalence in permanent teeth) compared with placebo varnish (low certainty).

Used fluoride mouth rinse vs No fluoride mouth rinse

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

Used fluoride mouth rinse showed no clear difference in fluorosis (percentage prevalence in permanent teeth) compared with no fluoride mouth rinse; GRADE not reported.
