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.

(July 2009). Enamel hypoplasia is a defect of the teeth in which the enamel is hard but thin and deficient in amount, caused by defective enamel matrix formation with a deficiency in the cementing substance.Usually the condition involves part of the tooth having a pit in it.In some cases, the natural enamel crown has a hole in it, and in extreme cases, the tooth has no enamel, which doesn't mean the tooth doesn't exist because dentin is also a component of teeth.sually the condition involves part of the tooth having a pit in it.
