There is considerable controversy as to whether dental amalgams may cause systemic health effects in humans because they liberate elemental mercury. Most such amalgams contain as much as 50% metallic mercury. To determine the influence of dental amalgams on the mercury body burden of humans, we have given volunteers, with and without amalgams in their mouth, the sodium salt of 2,3-dimercaptopro...

abstract   background and aim: due to the increasing use of restorative materials, finding a  suitable material with low adhesion rate and colonization of pathogenic  streptococcus mutans has a significant importance. the purpose of this study was the  comparison of the adhesion rate of streptococcus mutans to “nano-hybrid composite” and “amalgam” at 1, 3, and 7 day  intervals. methods and mate...

Introduction: Dental amalgam is a dental material that has been used to fill carious cavities for more than 150 years. Amalgam fillings contain about 50% mercury and mixture of other metals. The it contains controversial debated by many researchers, as there evidence its negative effects on the human body. constant release vapor from causing countries discontinue use in treating patients' teeth...

The survival rates of restorations in primary molars were calculated after a retrospective examination of patients' dental records from a study population of 1,065 children. A random sample of 128 records showing information for 604 dental restorations was examined, coded, and analyzed by the life table method of survival analysis. The order of the survival rate of restorations from higher to l...

The aim of this study was to assess the impact of environmental factors: cigarette smoking, dental amalgam fillings, eating habits and osteoporosis, on the concentrations of copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd) and mercury (Hg) in the bone of hip joint in patients in the Orthopedics Clinic in Szczecin, Poland. Amalgam dental fillings had an effect on the Cu concentration in the carti...

PLACE AND DURATION OF STUDY Department of Operative Dentistry, Fatima Jinnah Dental Hospital, Karachi, from January to June 2009. METHODOLOGY Patients aged 20 - 45 years attending the Departm...

Mercury (Hg) vapor is released from dental "silver" tooth fillings into human mouth air after chewing, but its possible uptake routes and distribution among body tissues are unknown. This investigation demonstrates that when radioactive 203Hg is mixed with dental Hg/silver fillings (amalgam) and placed in teeth of adult sheep, the isotope will appear in various organs and tissues within 29 days...

Mercury is a highly potent cell toxin with effects on human and animal nervous systems. Mercury vapour released from dental amalgam is the predominant source of mercury in the human adult and foetal central nervous system in populations of developed countries. Only in small populations with high consumption of methyl mercury containing fish can the contribution from fish consumption reach or su...

The aim of the present study was to compare the reduction of subjective complaints by 3 treatment strategies in 90 "amalgam patients" whose complaints could not be explained by a medical or psychological disorder. The individuals were randomly assigned either to removal of dental amalgam only (removal group), or removal in combination with a "biological detoxification" therapy with high doses o...

introduction: dentists are exposed to mercury vapor from dental amalgam in their routine occupational practice; excess exposure to mercury is harmful. the aim of this study was to assess the influence of some possible related factors on the urine mercury levels of general dentists and restorative specialists in mashhad in 2010. materials and methods: this cross-sectional study was performed ran...
