Abstract

Introduction: Periodontitis is a chronic inflammatory disease that destroys the supporting structures of the teeth and can lead to tooth loss. Obesity is a condition characterized by excessive fat accumulation in the heart and blood vessels. A potential association between obesity and periodontitis has been suggested, but further research is needed to clarify the relationship. Increased knowledge of this association could contribute to improved preventive strategies.

Aim: The aim of this study was to investigate the association between obesity and periodontitis.

Research question: Is there a difference in outcome based on gender?

Method: A quantitative analysis was conducted based on data from the Jönköping Study in 2013 and 2023. A well defined population sample was clinically and radiographically examined by dentists. Participants also completed questionnaires regarding general health, oral health, and lifestyle factors. BMI was categorized into normal weight, overweight, and obesity, and periodontitis was classified as none/mild, moderate, or severe. Statistical analyses were performed using SPSS with chi-square tests and correlation analyses.

Results: A weak but significant positive association was identified between obesity and the prevalence of periodontitis.

Conclusion: Obesity were weakly associated with periodontitis and may be a contributing risk factor.

Implications: The results highlight the importance of considering body weight in preventive dental care.
