Introduction: Turner's hypoplasia is classified as acquired dental dysplasia (dysplasia dentales acquisitae). Turner's hypoplasia is a localized tooth dysplasia. Most often one of the permanent teeth is affected, but a group of adjacent permanent teeth may also be affected.
Case Description: The survey was conducted in 2018/2019. It was conducted at the Faculty of Dental Medicine and the clinical offices of Pediatric Dental Medicine, Varna, Bulgaria. In order to conduct the study, we obtained informed consent from the parents of the patient, who is a child at 11 years of age. We have diagnosed Turner's hypoplasia on teeth 11, 12 and 21. The presence of hypoplastic and hypomineralized areas of the enamel of the occlusal 1/3 of the permanent incisor crowns affecting the cutting edges. Tooth 22 is with hypodontia dentis.
Discussion: Turner's hypoplasia is an anomaly found in the structure of permanent teeth. Its appearance is variable, although it usually manifests as part of missing or reduced enamel on permanent teeth.
Conclusion/clinical significance: A traumatic accident during childhood is the etiological reason for the development of Turner's hypoplasia on permanent teeth 11, 12, 21. Enamel hypoplasia has different variations and studies can be conducted to conclusion of their family habits.
