Enamel hypoplasia : ウィキペディア英語版
Enamel hypoplasia

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 of vitamin D in the body. 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.
==Causes==
It can be caused by any of the following:
*Trauma
*Bacterial infection
*Maternal drug use
*High fevers
*Malnutrition (prenatal and postnatal)
*Poor oral hygiene and or neglect
*Slow enamel formation〔(What is Enamel Hypoplasia? )〕
*Celiac disease〔(Celiac Disease, Oral Dis. 2013 Oct;19(7):635-41. doi: 10.1111/odi.12091. )〕
