چکیده
“frosted” appearance. _Enamel hypoplasia (EH) is a defect in tooth enamel that results in less quantity of enamel than normal. The defect can be a small pit or can be widespread that the entire tooth is misshaped with affected mechanical properties.4 EH can occur on single or multiple teeth.6 It can appear white, yellow or brownish in color with a rough or pitted surface.6,8 In some cases, the quality of the enamel is affected as well as the quantity.8 Environmental and genetic factors that interfere with tooth formation are thought to be responsible for EH. This includes trauma to the teeth, infections during pregnancy or infancy, poor pre-natal and post-natal nutrition, hypoxia, exposure to toxic chemicals and a variety of hereditary disorders.6
