Amelogenesis imperfecta represents a group of hereditary conditions that manifest
enamel defects without evidence of generalized or systenic disorders. These enamal
disorders are apparently heterogeneous in the basic chemical structure, resulting in a
dicerse presentation of clinical characteristics. The reported prevalence of amelogenesis
imperfecta varies from 1 in 14,000-16,000 to 1.4 in 1,000 depending on specific population
studied with the autosonal dominat hypocalification type of amelogenesis imperfecta
believed to be the least prevalent.
The most widely accepted current classification system for delineation the
amelogenesis imperfecta types considers the mode of inheritance and clinical
manifestations. Thress major group are recognized ; hypoplastic, hypocalcified, and
hypomaturation types, Delineation specific types of amelogenesis imperfecta can be
confusing due to the phenotypical similarity of many forms and that the most recent
classification lists 14 different types.
A 12 year-old female patient came to our pediatric dentistry clinic complaining of the
ugly shape and color of her teeth, especially the upper front area. Although the goal ot
the treatment was mainly focused on the improvement of patient¡¯s esthtics, longevity
of the reatorations was also considered in selecting the appropriate restorative system,
resin jacket crown, which can satisfy the both aspects.
