Both primary and permanent dentition could be affected by this condition. The pivotal characteristics are loss of the tooth structure, wear of enamel, and exposed dentinal areas at the occlusal surface of posterior teeth. AI may be inherited in autosomal dominant, autosomal recessive, or X‐linked types. Treatments of AI cases should be initiated in childhood and continue into adolescence. Considering that AI is a rare and heterogeneous condition, the dental team faces various difficulties regarding choosing the appropriate treatment plan. The oral rehabilitation of patients with AI is a challenging condition that needs a multidisciplinary approach. Many treatment options have been reported for solving cosmetic and restorative problems in AI cases. The conservative treatment plan in this hypoplastic-hypomature AI case included esthetic rehabilitation with a sequential method, innovative non-invasive pulp-therapy methods, and dental restorations under oral sedation. The written consent for the treatments was obtained after consultation with the child and his parents.
