Abstract

Multiple supernumerary teeth usually occur with a syndromic disease, and there are very few occurrences in non-syndromic cases. They frequently occur in the premolar region, while they are rare in the midline region of the maxilla. We report a case of four supernumerary teeth in both the midline region of the maxilla and premolar region of the mandible. The patient was a 12-year-old boy referred to our hospital for examination in July 2020. He had no syndromic disease nor familial tendency. According to panoramic x-ray, eight supernumerary teeth were observed in the midline region of the maxilla and premolar region of the mandible.
