To assess the prevalence and severity of periodontal disease of the Rohingya refugees and host community in Bangladesh.

An unpublished pilot was conducted for the sample size calculation. Two-stage cluster sampling method was used to select 50 participants from refugee camps and 50 from the host community. Structured questionnaire and periodontal examination were completed. Composite measures of periodontal disease were based on the World Workshop (WW) and Centers for Disease Control and Prevention-American Academy of Periodontology. Linear regression models, for clinical attachment level and periodontal pocket depth (PPD) and ordered logistic regression models, for composite measures, were fitted to test the association of periodontal measures and refugee status.

Compared to the host community, a smaller percentage of refugees reported good oral health-related behaviours. Refugees exhibited lower levels of bleeding on probing but higher PPD, hence a higher proportion had severe stages of periodontitis.

As per the WW, prevalence of periodontal disease was 88% and 100% in the host and refugee groups, respectively. In the unadjusted models, refugees were three times more likely to have severe stages of periodontitis; this association was attenuated when adjusted for confounders (sociodemographic variables and oral health-related behaviours).

Prevalence of periodontitis was high both in the host community and refugees. The refugees exhibited a more severe disease profile. The oral health of both groups is under-researched impacting the response of the health system. Large-scale research systematically exploring the oral health of both groups will inform the design and delivery of community-based interventions.
