A total of 253 subjects were randomly assigned to receive amalgam fillings and 254 to receive resin composite fillings
for their existing caries as well as for any more that developed over 7 years of follow-up.
Dr Hempleman removes amalgam fillings daily, replacing them with composite fillings
, but says the procedure can be hazardous because of the release of mercury particles.
Universal testing machine was fixed at a crosshead speed of 0.5mm per minute using a span of 20mm Force recorded to produce the fracture for specimens produced by nano hybrid composite filling
material Nexcomp (Meta Biomed Co; Ltd.
Aesthetics - the shade/color of the composite fillings
can be closely matched to the color of existing teeth.
Among the tested techniques, total etch technique with incremental filling of composite is the one taken as standard technique for composite fillings
. Most of the samples in this technique like other techniques showed high leakage scores (table 2).
The researchers found that overall, there were no major differences between patients receiving amalgam or composite fillings
in terms of filling failure rates.
Gan also detailed the procedures to be done on Revilla, including a panoramic radiograph and composite fillings
on his upper frontal teeth.
There is extensive evidence documenting that composite fillings
are leak proof, few pertinent data are available for biodentin yet.
Many people with amalgam fillings today are also having them taken out and replaced with composite fillings
to remove any mercury in the amalgam and for esthetic purposes.
More studies are needed but it may be wise to avoid bisGMA-based composite fillings
The Norwegian and Swedish bans come at a time when alternative composite fillings
have become strong enough to replace amalgams under practically any circumstance.
Beginning in 1997, the team followed 507 Portuguese children aged 8-12 years who received either amalgam or resin-based composite fillings
, conducting clinical neurologic exams to assess two types of neurologic signs: hard (indicating damage to specific neural structures), and soft (subtle signs of central nervous system dysfunction that likely point to immature sensory-motor skills rather than to any structural damage in the brain).
