Parts of the crater walls eventually collapse back into the crater, the vent is filled with loose material, and, if the crater still is deeper than the water table, the crater fills with water to form a lake, the lake level coinciding with the water table.
Poor Dentition. My provider likes to use poor dentition in his assessment as a billable diagnosis, however there is not really a good code to select. Sometimes he is referring to a patient who is missing teeth due to poor oral hygiene, sometimes it is a patient with alot of tooth decay, in this case, he is referring to a patient with loose wisdom teeth.
Tooth decay is the destruction of the outer surface, or enamel, of a tooth. It is caused by acid buildup from plaque bacteria, which dissolves the minerals in the enamel and creates cavities.(Illustration by Electronic Illustrators Group.).avity â A hole or weak spot in the tooth surface caused by decay. Dentin â The middle layer of a tooth, which makes up most of the tooth's mass. Enamel â The hard, outermost surface of a tooth. Fluoride â A chemical compound containing fluorine that is used to treat water or applied directly to teeth to prevent decay.
