Analyses of 1100 supernumerary teeth in a nonsyndromic Turkish population: A retrospective multicenter study.
OBJECTIVE
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.


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.
