Blood and skin carotenoid levels are inversely associated with the prevalence of periodontal diseases in populations with normal occlusion: a cross-sectional analysis from the Iwaki health promotion project

Key Points

• Carotenoid levels are linked to lower prevalence of periodontal diseases among individuals with normal occlusion.
• This analysis highlights that higher blood and skin carotenoid levels may correlate with healthier gums.
• Using cross-sectional analysis from the Iwaki health promotion project, the study assessed health indicators and dietary factors.
• These findings suggest that increasing carotenoid intake could have implications for gum health, but further research is needed.
