Social support associated with restorative treatment, professionally applied fluoride and flossing: A cross-sectional analysis including recent immigrants from Central America and Mexico in the Midwest USA.

While higher social support was linked to beneficial outcomes for oral health in Mexican immigrants, the opposite was found in Central Americans. These findings highlighted the complexities of social relationships among new immigrants, and potential heterogeneity within the Hispanic population, particularly regarding social and behavioural measures as they pertain to oral health. Further research is needed to identify the underlying mechanisms producing both differences in social support and oral health outcomes.
