Purpose: The aim of this study was to determine the effect of the patient’s age, gender and race/ethnic on the shade and mold of the maxillary anterior teeth.

Methods: After IRB approval, a computer program was written to identify a list of patients from the Electronic Health Record database and to record demographic and tooth selection information from patients treated with at least one complete maxillary denture. Data was manually collected from tooth prescription forms and confirmed with a corresponding review of the EHR for 1,265 patients. Statistically, cross tabulations were constructed and the chi square test employed. The Mann-Whitney “U” test and the Kruskal-Wallis test were used to compare groups.

Results: Chi square tests revealed significant p values for gender versus tooth form (p < 0.001), width (p < 0.001) and shade (p < 0.001), but not significant for gender versus facial contour. Similarly, the p value was not significant for ethnicity versus tooth contour. The Mann-Whitney “U” test revealed significant p values for gender versus width and shade. The Kruskal-Wallis test for variables ethnicity and age versus the width (p < 0.001) and shade (p < 0.025) revealed significant p values.

Conclusion: Shade selection for the maxillary denture teeth was influenced by the age, gender and ethnicity of the patient. Similarly, the age group 40 - 49 had lighter shades selected than did patients in age group > 70. Female patients had lighter and narrower teeth selected than the males, and there was no difference in the facial contour of the teeth selected relative to age, gender or ethnicity.
