No trails available on best restorative treatments for amelogenesis imperfecta


Amelogenesis imperfecta (AI) is a genetic disorder that presents as an abnormal formation of enamel. AI can have a range of inheritance patterns and the exact incidence is uncertain with estimates ranging from 1:700  to 1:12-14,000. Clinically, AI can be classified into four categories: hypoplastic (type I), hypomaturation (type II), hypocalcified (type III), and hypomature [read the full story…]
