Sources for Enamel hypocalcification
How did you find out about all that information in Enamel hypocalcification? If you found it out from reliable sources, whether it's a book, scientific journal, website, or another type of reliable source then you can be the one learn how to add those sources in from Help:Referencing for beginners because nobody else will be able to find those sources to add them in. Bad reference format like the second reference of Enamel hypoplasia is better than no reference. Somebody else will probably eventually fix the reference format. Although people are allowed to add information to a Wikipedia article that they can't find a source for because other people might find one later, it usually gets deleted after a long time if it's determined to be pretty sure that such a source doesn't exist.
