Status of mercury in dental patients and the relationship between mercury from dental amalgam and the cardiovascular system

ABSTRACT

This study involved 120 persons divided into 4 groups each of 30 persons 15 male [male sign] and 15 female [famale sign]. All were admitted to the dentistry clinic. The first group [I] acted as a control group. The second group [II] involved persons with one filling tooth. The third group [III] involved persons with two filling teeth. The fourth group [IV] involved persons; with more than two filling teeth. The study showed significant increase in urinary mercury [U-Hg], blood mercury [B-Hg] and mean arterial blood pressure in groups [III] and [IV]. Comparison between persons with and without amalgam showed that groups III and IV had significant decrease in hearth rate, hemoglobin, hematocait and red blood cell count [BRCs]. The work showed that the more amalgam, the larger increase in mercury levels
