title: Ethnic inequalities in periodontal disease among British adults.
abstract: To explore ethnic inequalities in periodontal disease among British adults, and the role of socioeconomic position (SEP) in those inequalities.
  
  
  
  We analysed data on 1925 adults aged 16-65 years, from the East London Oral Health Inequality (ELOHI) Study, which included a random sample of adults living in an ethnically diverse and socially deprived area. Participants completed a questionnaire and were clinically examined for the number of teeth with periodontal pocket depth (PPD)≥4 mm and loss of attachment (LOA)≥4 mm. Ethnic inequalities in periodontal measures were assessed in negative binomial regression models before and after adjustment for demographic (gender and age groups) and SEP indicators (education and socioeconomic classification).
  
  
  
  Compared to White British, Pakistani, Indian, Bangladeshi and Asian Others had more teeth with PPD≥4 mm whereas White East European, Black African and Bangladeshi had more teeth with LOA≥4 mm, after adjustments for demographic and SEP measures. The association of ethnicity with periodontal disease was moderated by education, but not by socioeconomic classification. Stratified analysis showed that ethnic disparities in the two periodontal measures were limited to more educated groups.
  
  
  
  This study showed considerable ethnic disparities in periodontal disease between and within the major ethnic categories.
