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. )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「enamel hypoplasia」の詳細全文を読む スポンサード リンク
