Abstract

Purpose

Supernumerary teeth (SNT) are teeth or tooth-like structures that have erupted or might erupt in addition to the twenty primary or thirty-two permanent teeth. The simultaneous presentation of multiple SNT, syndrome-related multiple SNT, SNT inside the maxillary sinus, and treatment outcomes were analyzed for developing improved diagnosis and management plans.

Patients and Methods

This retrospective study reviewed the medical records of National Cheng Kung University Hospital patients who had undergone surgical intervention with general anesthesia between February 2014 and November 2017, analyzed panoramic radiographs and cone-beam computed tomography (CBCT) scans of their multiple SNT, and used descriptive statistics to discuss treatment and relative complications, especially of unusual SNT.

Results

The records of 165 patients (male/female: 127/38; mean age: 12.4 years) with 241 SNT (120 had one SNT; 35 had two; 3 had three; 2 had four; 2 had five; 2 had six; and 1 had twelve) were reviewed. There were 185 SNT in the maxilla and 56 in the mandible; 153 were mesiodens and 115 were inverted; 142 were asymptomatic and 137 were conical; 228 were fully impacted and 210 were partial roots. Two patients had SNT inside the maxillary sinus and one had five SNT and Marfan syndrome. Two patients had postoperative lip or chin paresthesia, and 2 had postoperative sinusitis.

Conclusion

Patient demographics provided useful epidemiological information. We recommend panoramic radiographs and CBCT for managing patients with possible multiple SNT and for extracting SNT.
