This study aimed to clarify the relationship between workers' masticatory strength, health, and risk of falling accidents. The participants were plant A workers, twenty-nine men and five women, who applied for fall accident risk assessment. Masticatory strength was measured by the “masticatory strength scale," which comprised three subscales of “masticatory situation-related factors," “tooth-related factors," and “oral health behavior-related factors." Health status was measured using the number of diseases, number of subjective symptoms, and subjective sense of health. In fall accident risk assessment, we used the eyes-closed one-leg test and two-step test to evaluate balance ability, lower limb flexibility and muscle strength respectively. Spearman's rank correlation coefficient was used for analysis. Results showed that there was a correlation between men's masticatory strength and their ability to stand on one leg with their eyes closed. Additionally, there was a correlation between men's masticatory strength and number of diseases. A relationship was found between masticatory strength, balance ability, and health status, which suggested that masticatory strength may influence workers' health and risk of falling accidents.
