The clinical manifestation of periodontal diseases (such as gingivitis and chronic periodontitis) results from a complex interplay between the etiologic agents such as bacteria that present in the dental plaque, genetic factors, systemic diseases, smoking and exposure of some heavy metals, such as mercury. In this study, we aimed to evaluate hair mercury levels in healthy subjects in comparison with periodontal patients.

Materials and methods

One hundred twenty subjects were enrolled in this study. The included persons were divided into 3 groups: healthy subjects (n = 40), gingivitis (n = 40) and chronic periodontitis patients (n = 40). Hair samples were collected from occipital area of head. Total mercury levels were determined by atomic absorption spectrophotometry.


The difference between mercury levels in three groups were statistically significant (p-value < 0.001). Mercury level in periodontitis patients was greater than the gingivitis group (p-value < 0.001). In addition the differences between mercury levels in periodontitis patients vs healthy individuals was significant (p-value = 0.048). The gingivitis patients had lower levels of mercury than the control group, but the difference was not significant (p-value = 0.170).


The results showed that the levels of mercury are to some extent differed in periodontal diseases in comparison with the healthy individuals. A study with larger sample size is needed for clarification of this issue.
