132 - Comparison of Pediatric Stainless Steel Crown Sizes Among Patient Ethnicities and Gender

Abstract:

Purpose: The purpose was to determine if pediatric stainless steel crown sizes vary by ethnicities and gender.
 

Methods: A retrospective chart review was performed on patients treated for full mouth dental rehabilitation in the operating room by a single credentialed pediatric dentist during the period of 01/01/2018 to 08/01/2024. Data included age at time of FMDR, gender, ethnicity, and stainless steel crown sizes placed on primary molars. A Kruskal-Wallis and Mann-Whitney statistical analyses were completed to determine if there were statistical differences in sizes among the ethnic groups as well as between genders.
 

Results: After incorporating the inclusion and exclusion criteria, 185 patients and 857 teeth were included in the analysis. A Krukal-Wallis Test proved statistically significant differences in ethnic group median crown sizes for teeth #A, I, J, and T for male children only. No differences were found among the ethnic group median crown sizes for female children. A Mann-Whitney Test confirmed statistically significant SSC sizes between males and females for teeth #B, I, J, L, S, T. Lastly, males had larger crown sizes than females for all teeth.I/p>
 

Conclusions: While deciding on SSC sizes for permanent teeth, males will typically have a larger crown size than females. Furthermore, we were not able to confirm certain ethnicities to have statistically larger crown sizes than others, however, for some teeth, there were differences in the males to include #A, I, J, and T. In comparing males to females, males had statistically larger crown sizes for teeth #B, I, J, L, S, T. As a result, one may infer to use larger initial crown sizes for some teeth for male patients. Further post-hoc analysis with more data points needs to be completed to confirm if there are differences between certain ethnicities.
