Socio-Economic Factors and Tooth Loss in Young Adults With Periodontitis

Objectives: To investigate the relationship between education/income and tooth loss over 10 years in young adults with periodontitis
Methods: This register-based study was conducted retrospectively on 471 patients aged <36 years who had been diagnosed and treated for periodontitis at two specialist clinics in periodontology in Stockholm Sweden between 2003 and 2009. A majority had periodontitis Stage 3 and Grade C at baseline. The variables were collected from the baseline clinical examination and from two national healthregisters; the Swedish dental health register at the National Board of Health and Welfare and the LISA register at SCB Statistics Sweden. The tooth loss between the years 2009-2019 was registered. Statistical analyses were performed with negative binomial regression. Confounding variables to the relationship between tooth loss and education/income were included in the analysis.
Results: The mean number of lost teeth due to periodontal reasons during the follow-up period was 1.4 (range 0-26). The tooth loss was significantly (p=0.004) lower for individuals with a post-secondary education >3 years while income had no influence on tooth loss. The confounders smoking, interruption of specialist treatment and age were significantly correlated to tooth loss.
Conclusions: Tooth loss for young adults with periodontitis, was significantly lower among the group with a post-secondary education >3 years, when adjusted for confounding variables.
