BACKGROUND The effect of MRI on microleakage of amalgam restorations is an important health issue that should be considered. If MRI application causes increase of microleakage, amalgam fillings should be reassessed after MRI and replaced if necessary. OBJECTIVES The aim of this study is to compare the effect of magnetic resonance imaging (MRI) on microleakage of class II bonded amalgam versus...

Amalgam is a wonderful restorative material that has been used in dentistry for over 150 years. Millions of people world-wide have at least one dental amalgam restoration, and have not suffered any adverse effects. It is easily placed, relatively cheap and durable. It expands while setting thereby creating a tight marginal seal. If moisture is incorporated there will be some increased expansion...

More recently, many studies reported that amalgam may constitute potential toxic hazards to patients through mercury release and absorption, surface corrosion, and...

The posterior restorative material of choice depends on the individual clinical situation and patient. Amalgam has a long history of use and clinical success. Esthetic restorations are increasingly in demand, and include glass ionomers, compomers and composite resins. Fluoride release is a desirable attribute in a restorative material, as are wear resistance, low polymerization shrinkage and lo...

14 To examine possible association between dental amalgam fillings and mercury burden, we measured the mercury concentrations in scalp hair samples from 74 female Japanese subjects aged 26-64 years who had a dietary habit of little fish-consumption. The hair mercury concentrations in the subjects with multiple amalgam fillings were significantly higher than those in the subjects with no amalgam...

Adhesive techniques are now used for many dental restorative materials, including amalgam. Several generations of dentine bonding agents have been developed, mainly for bonding composite resins. When bonding is used with amalgam restorations, the need for retention and resistance form is reduced, the seal is improved, and some procedures, such as amalgam sealants, which were not previously poss...

There is significant public concern about the potential health effects of exposure to mercury vapour (Hg(0)) released from dental amalgam restorations. The purpose of this article is to provide information about the toxicokinetics of Hg(0), evaluate the findings from the recent scientific and medical literature, and identify research gaps that when filled may definitively support or refute the ...

Amalgam has been the material of choice for restoring posterior teeth for more than 100 years. The past 25 years have witnessed significant advances in restorative materials themselves and in the bonding systems for retaining a restoration in the prepared tooth. As a result, there has been a shift toward resin composite materials during this same period because of concerns about the esthetics a...

OBJECTIVES This study evaluated the effect of surface polishing on mercury release from dental amalgam after treatment with 16% carbamide peroxide gel. MATERIALS AND METHODS Ninety-six samples from two different amalgam brands were prepared in truncated cone-shaped PVC polymer molds with an external surface area of 195 mm(2). Half of the specimens were polished with green and red rubber, a br...

Clarkson and Magos (2006) provide their perspectives on the toxicology of mercury vapor and dental amalgam. As scientists who are involved in preparing a German federal guideline regarding dental amalgam, we welcome additional scientific data on this issue. However, Clarkson and Magos do not present all the relevant studies in their review. The additional data provided here show that: (a) Denta...
