Older research shows that amalgam restorations
routinely last longer than composite, exhibiting better wear, durability, and longevity.
This article describes a reduced-step approach for exchanging amalgam restorations
with composite resins using a base of flowable bulk-fill resin as a dentin substitute in combination with a final layer of conventional composite resin to replace the enamel and achieve anatomically and esthetically acceptable results.

Marginal ditching and staining as a predictor of secondary caries around amalgam restorations
: a clinical and microbiological study.
Aim: This was to evaluate the effect of different thicknesses of cavity walls on fracture strength of pulpotomized primary molar teeth with class II amalgam restorations
. Methods: 80 carious extracted human primary molar teeth were selected for pulpotomy preparation.
Our study revealed that 41% of the respondents never used rubber dam in amalgam restorations
, while 26% never used it in composite restorations.
However, due to increasing aesthetic concerns of the military population and public concerns over the safety of amalgam restorations
due to the perceived effects of mercury, amalgam restorations
may no longer be the consumer or provider restorative material of choice.
The Median Survival Time (MST) reported for class II amalgam restorations
placed in three year olds was 11 months which rose to 44 months in 7 to 8 year olds [Holland et al., 1986].
Composite fillings overcome previous amalgam fillings because they are superior in esthetic and able to be bonded to enamel and dentin.1 There is less tooth structure loss in composite cavity preparation when compared to the placement of a similar amalgam restoration
and it has been shown that there is strengthening of the remaining tooth structure after placement of composite resin restoration.2 Composite resin has also been shown to have low cusp fracture rates in crown build up restorations.3
