A clinical case report of hypodontia and impacted supernumerary teeth in a patient diagnosed with Yunis-Varon syndrome

Abstract

INTRODUCTION: Yunis-Varon syndrome (YVS) is an extremely rare autosomal recessive congenital disorder affecting many organs and systems (bones, ectodermal structures, the cardiorespiratory system, etc.). Abnormalities include aplasia or hypoplasia of the clavicles, facial dysmorphism, sparse hair, absence or hypoplasia of the thumbs, toes and distal phalanges, prominent auricles, shortened upper lip and other skeletal deformities, such as pelvic dysplasia, kyphosis, scoliosis, etc. Tooth structures and jaws are characterized by marked micrognathia, a narrow high-arched palate, hypodontia, impacted permanent teeth as well as supernumerary teeth. AIM: The present case report aims to describe the clinical and radiographic changes in the masticatory apparatus of a patient diagnosed with Yunis-Varon syndrome. CASE PRESENTATION: The subject of this study was а patient, suffering from pain in tooth #38. The clinical intraoral examination revealed hypodontia, but the radiographic image revealed many supernumerary teeth in the anterior and premolar region of both the maxilla and the mandible. RESULTS: In addition to skeletal anomalies and impaired ectodermal structures, this rare syndrome can cause disturbances in the teeth and jaws. For this reason, dental specialists play an important role in the diagnosis and treatment of patients suffering from Yunis-Varon syndrome. CONCLUSION: Early intervention is important in Yunis-Varon syndrome. Future investigation will permit identification of thеsе skeletal and dental abnormalities.
