The impact of oral health on physical fitness: A systematic review

Abstract

Background

Oral health problems may have numerous effects on general health, including physical fitness and performance. In this review, we aimed to systematically review the available evidence to assess the effect of oral health on general physical fitness.

Methods

We systematically performed a literature search in two different databases (PUBMED and EMBASE) without restriction to the year of publication. Articles were included if the subjects were humans and the primary aim was to assess the effects of dental and/or oral health problems on physical activity using either objective physical measurements or physical performance tests. The quality of the studies was then assessed using a Joanna Briggs Institute (JBI) Critical Appraisal tool.

Results

A total of 2651 articles were initially retrieved from the systematic search of the literature. Of these, a final total of 11 articles following the inclusion criteria were included in the review. All of the 11 articles included in the review had good methodological quality. Of the 11 articles, ten articles suggested a correlation between dental and oral condition toward physical fitness, body balance, cardiorespiratory function, and also cognitive function. Only one article found contradictory results, which showed that periodontal conditions did not correlate with the cardiorespiratory function. Malocclusion, including the number of remaining teeth, was reported in five studies (45.4%), periodontal disease was evaluated in six studies (54.5%), along with slight evaluation of periapical inflammation.

Conclusion

This review suggests that there is a negative effect of poor dental and/or oral health on physical fitness and performance.
