Aim: This study was conducted to investigate the level of mercury transmitted into the blood and hair of rabbits based on the number of amalgam-filled teeth present in the mouth. Methodology: A total of 18 male rabbits from New Zealand were used in the study. The rabbits were separated into 3 groups: a control group, a dichotomous amalgam-filled group, and a quadruple amalgam-filled group. Blood samples were collected from the animals before fillings and after 24 hours, one week and one month after the fillings were applied. Hair samples were taken before the fillings were applied and at one month after. Blood and hair samples were taken from the rabbits, and the transfer of mercury was measured with the hydride system in the absorption spectrophometer. Results: The data obtained from the study were evaluated using the SPSS 21 package program. As compared with the control group at the 24th hour, no statistical difference was seen between the dichotomous and quadruple amalgam filling groups in terms of blood mercury level (P>0.05). However, the levels of blood mercury observed one week and one month later were significantly higher than in the control group observed at the same times (p<0.05). Over each time period measured, the level of blood mercury was found to be similar between dichotomous and quadruple amalgam filling groups (p>0.05). Conclusion: Mercury could not be detected in hair samples. As a result, it was revealed that amalgam fillings affect the blood mercury level.
