When an Overwhelming Number of Supernumerary Teeth Provides an Alternative to the Diagnosis of Trichorhinophalangeal Syndrome.

Abstract

Background: The prevalence of supernumerary teeth is increasing in modern dental practice. However, the presence of multiple supernumerary teeth should be further investigated. Proper diagnosis of an underlying syndrome might save the patient from future health hazards through early diagnosis and optimal follow-up screening. Case Presentation: A 13-year-old female patient presented with multiple retained deciduous teeth and delayed eruption of permanent teeth. Although the medical and family history of the patient did not raise any concerns, the clinical and radiographic examinations yielded intriguing findings. The patient presented with a total of 11 supernumerary teeth, which impeded the normal eruption of permanent dentition in addition to the presence of retained deciduous teeth. Additional clinical and laboratory investigations were conducted in response to the case's complexity, resulting in the diagnosis of Trichorhinophalangeal Syndrome (TRPS) Type I. The patient underwent a precise treatment plan and then was followed up for 6 months postoperatively to monitor the eruptive movement of the permanent teeth. Conclusion: When a syndrome is the underlying cause, monitoring unusual cases, such as those with multiple supernumerary teeth, can be lifesaving or aid in the early diagnosis of more serious complications.
