Abstract:
Amelogenesis imperfecta (AI) is a group of hereditary conditions that affect enamel formation. It is associated with a high morbidity for the patients and may present major restorative and sometimes orthodontic challenges for the dental team. Early recognition followed by appropriate preventive and restorative care is essential in the successful management of AI. A multidisciplinary approach with careful planning from early childhood will maximise the treatment options available for the permanent dentition and optimise the final outcome. In this case, a team consisting of two paediatric dentists, an orthodontist, a restorative dentist, and an oral and maxillofacial surgeon were involved in the management of the patient over a 12-year period. Treatment included preventive advice, interim composite restorations, two phases of orthodontic treatment, orthognathic surgery and placement of cast crowns. The patient is extremely happy with the result.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
