356 - Prevalence of Supernumerary Teeth with Regards to Location, Orientation, Number, and Morphology in Hispanic vs. Non-Hispanic Populations; A Retrospective Chart Review

Purpose: The purpose of this retrospective chart review was to contribute to the current research focused on supernumerary teeth in Hispanic vs. Non-Hispanic patients, primarily emphasizing location, orientation, number and morphology of the supernumerary teeth. 

Methods: Electronic chart records of patients at El Rio Community Health Center who were diagnosed with one or more supernumerary teeth between the dates of 01/01/2015 to 11/31/2020 were reviewed.  Data was obtained for each patient in regards to age, ethnicity, gender, frequency, tooth number, location, orientation, shape, and treatment. 

Results: A total of 41 teeth were evaluated from 32 patients. The mean age was 14.1 years with 90.2% being male and 9.8% being female.  90.2% of the patients were Hispanic and 9.8% were Non-Hispanic. 82.9% (34 teeth) were diagnosed as either tooth #58 or tooth #59. 95.1% (39 teeth) were located in the maxilla. 14.6% (6 teeth) were inverted.  31.7% (13 teeth) were categorized as peg shaped, 26.8% (11 teeth) were categorized as normal shaped, 9.8% (13 teeth) were categorized as conical in shape, and 31.7% (13 teeth) were categorized as generally rudimentary.  87.8% (36 teeth) were treated with extraction.   There was a statistically significant difference (P < 0.05) between tooth number and treatment, with tooth numbers 58 and 59 receiving more treatment.  There was a statistically significant difference (P < 0.05) between supernumerary teeth and treatment, with more teeth receiving treatment than not.


Conclusions: Supernumerary teeth are more likely to receive treatment than not, with teeth #58 and #59 more likely to receive treatment.
