Caries responsible for enamelogenesis imperfecta (MIH) is considered comparatively rare. But, when a higher rate of caries can be controlled through the early detection of congenital failure such as an enamelogenesis imperfecta, then correct treatment at the right time becomes important. 8 clinical cases are shown here. Jasulaityte, et all. reviews an expression rate of enamelogenesis 5.9%〜25% are imperfect. Intraoral digital pictures of 108 patients at the age of 12 when they visited our dental office were examined on a computer.
The teeth with white opacity, yellow opacity, yellow-brown demarcated opacity and enamel loss are defined as enamelogenesis imperfecta. Expression was recognized on front teeth, molars and also second molars with in 12 in 108 samples (11.1%).

Healthy teeth increase with a decrease of caries, but enamelogenesis imperfecta, central tubercle and deeper fissures develop at a constant rate. Therefore, intraoral examination with knowledge of their expression rate is important.
