The purpose of this study was to establish the relationship between educational status, family income, social inequality, and the Human Development Index (HDI) with the need for tooth extraction.
The authors conducted a 3,964 patients retrospective cohort, from 2007 to 2017, assessing gender, age, hometown, family income, general health data, educational level, extracted teeth, and cause of the extraction.
Females were predominant in a 1.5:1 ratio. The average number of removed teeth was 2.27 per patient. Third molar extraction was correlated with wealthier patients (p = .01), while poorer patients opted for the removal of other functional teeth. Neither social inequality nor human development promoted a correlation between which teeth were removed. Uneducated and poorly educated were related to the removal of other teeth, molars, and anterior teeth, rather than third molars (p = .032). Educated ones, with a college education and high school, preferably remove their third molar, without any other loss of permanent teeth (p = .006).
Wealthy and educated patients are aware of oral health promotion programs, and usually seek elective treatment, especially third molars extractions, while the poor and uneducated are demanding treatment for functional teeth removal, worsening chewing, and aesthetics.
