Demographics of Individuals Extracting Root-filled Teeth in Sweden

• Objectives: To study some demographic variables of individuals registered receiving a root canal filling in a tooth that during the subsequent 5 to 6 years was registered as being extracted in comparison of individuals retaining the equivalent root-filled tooth during the same period.Methods: Data from the Swedish Social Insurance Agency were analyzed regarding all teeth that were reported root-filled in Sweden during 2009. The upper first molars were chosen to be a model for the comparisons. A control group was constructed by randomly selecting individuals with upper first molars not extracted. Demographical data on the individuals were received from Statistics Sweden and the groups were studied in regard to gender, age, ethnicity, mean income, educational level and civil status.Results: During 2009 a total of 36,139 upper first molars was registered as being root-filled and during the subsequent 5 to 6 years 4,362 (12.9%) of these teeth were registered as being extracted. The studied demographic variables were almost equal between the individuals who had their root-filled teeth extracted and the individuals in the control group who retained their root-filled teeth. The individuals extracting was in average older (52.7 years) than those retaining (51.1 years). A larger percentage of women (51.8) than men (48.2) was found in the group whose teeth were extracted.Conclusions: Demographic variables differed somewhat in regard to gender and age in individuals extracting root-filled upper first molars compared to individuals retaining their teeth. In regard to ethnicity, mean income, educational level and civil status only minor differences were detected.
