The amalgam restoration
of 46 was removed and access gained into the pulp chamber.
Amalgam continues to serve as an excellent and versatile material in dentistry for more than 150 years, with an estimated 100 million Americans having amalgam restorations
However, CBCT images were found to be superior to intraoral techniques in other studies for secondary caries lesions under both composite and amalgam restorations
(19)-(22) This finding is supported by the results of the systematic review which showed that glassionomer had a higher caries-preventive effect than amalgam restorations
in permanent teeth, with no difference in primary teeth.
Exposure to mercury by dental health workers is associated with amalgam restorations
in dental practices.
Mercury release from dental amalgam restorations
after magnetic resonance imaging and following mobile phone use.
F, The development of resin-bonding for amalgam restorations
Chadwick RG et al reported that bonded amalgam restorations
demonstrated greater longevity over non bonded amalgam.
(14) A poorly placed, incompletely cured composite will not last as long as, or function as well as, an amalgam restoration
. The belief held by many dentists that high risk caries patients should not receive composite restorations is another reason that amalgam restorations
are favored by Army dentists.

* Traditional Restorative Treatment involves the complete removal of soft, demineralised tooth tissue using predominately rotary instruments, followed by restoration of the tooth with either a plastic- or amalgam restoration
, requiring use of LA.

longevity: a systematic review.
Since the obturated canals were to be stored for 10 months, the coronal 2 to 3 mm of gutta-percha was removed with the System B, sealed with a 2 to 3 mm amalgam restoration
(Tytin amalgam, Kerr Corporation, Orange, CA), and stored in 100% relative humidity at 37[degrees]C for 10 months.
Similar values of specificity for all methods at the enamel threshold mean that all methods performed similarly in identifying a sound site around an amalgam restoration
. All methods presented specificity superior to 0.80, which is a minimum value to assure a minimum false-positive fraction.
