A Comparison of Oral Health Between Multiple Sclerosis Subjects with Dental Amalgams and Those with Amalgams Removed

93 Abstract The findings presented here suggest that mercury poisoning from dental amalgams may play a role in the etiology of oral health disorders in multiple sclerosis (MS) patients. Comparisons between MS subjects with dental amalgams and a control group of MS subjects without amalgams found significantly fewer oral cavity symptoms per subject in the amalgam-removal group during twelve months. They had fewer symptoms of metallic taste, foul breath, grinding teeth, and loss of taste. MS subjects with amalgam removal had significantly higher counts of total T-lymphocytes, T-8 suppressor cells, and a lower T-4 helper to T-8 suppressor ratio. The MS amalgam group had significantly lower levels of IgG, and the female MS amalgam subjects had significantly lower levels of IgM. The hair mercury levels of MS patients were significantly higher when compared to a control group of non-MS subjects.
