Group 0 name Corresponds to the control (unexposed) group for case-control studies
Healthy
Group 1 name Corresponds to the case (exposed) group for case-control studies
M&S (Moderate/Severe)
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
This group includes participants diagnosed with dental fluorosis according to the Dean’s Index, specifically those categorized as Code 4 (moderate) and Code 5 (severe). Code 4 (Moderate): Characterized by extensive brown or yellow-brown staining with mild enamel wear. Code 5 (Severe): Characterized by deep stains, obvious pits, and increased enamel brittleness.
Group 0 sample size Number of subjects in the control (unexposed) group
9
Group 1 sample size Number of subjects in the case (exposed) group

Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
6 months
