Odontogenic cysts arise from tissues involved in tooth development. These do not have a true epithelial lining, so technically they aren't true cysts.
Sterilisation
Antiseptic = chemical applied to living tissue/skin to inhibit or kill microorganisms. Disinfectant = chemical used on inanimate objects/surfaces to destroy pathogenic microorganisms.
Fluoride
G.V. Black and Frederick McKay investigated mottled enamel. H. Trendley Dean systematically investigated fluoride concentration in drinking water and dental fluorosis.
Study Designs and related

Mann–Whitney → Wilcoxon → Kruskal–Wallis → Spearman. Sampling = selecting a subset of people from a population. The extreme value of 18 pulls the mean upward, while the median remains 3.
