OpenAlex English

PURPOSE: The aim of this study was to analyze the clinical and radiological features of supernumerary teeth (ST), record the related complications, and discuss different forms of treatment. MATERIALS AND METHODS: A total of 111,293 patients were examined over a 3-year period. The patients' ages and genders, in addition to the number, morphology, location, position, shape, developmental stage, and eruption status of ST and associated complications, were recorded. RESULTS: Among the 111,293 patients, there were 851 (0.76%) patients with 1100 ST. Of these patients, 478 (56.2%) were males, and 373 (43.8%) were females, with a mean age of 22.71. Most of the 1100 ST were located in the maxilla, 437 (39.72%) were a conical shape, with 82.81% of these including a fully developed tooth. A mesiodens was the most common type of supernumerary tooth (n=284, 33.37%), followed by distomolars (n=204, 23.97%) and parapremolars (n=146, 17.16%). Among the 1100 ST, 422 (38.36%) were associated with complications. CONCLUSIONS: No previous studies in the literature have examined in detail so many cases with ST. The demographic profile of the patients with ST presented herein provides useful additional epidemiological information.
