An amalgam should be developed with a stable microstructure that, once set, would not change during clinical use. dental amalgam alloy and an alloy/mercury ratio (Nadal et al, 1961 a and b, MacRae et al, 1962, Wilson and Ryge, 1963, Mahler et al, 1970) In this dissertation attention will be paid to some of the material factors in determining for the whole or partially the durability of dental amalgam Costa SM, Martins CC, Bonfim Mde L, Zina LG, Paiva SM, Pordeus IA, et al. Amalgams can be divided roughly into two groups by their copper content: low Cu (traditional) and high Cu.

The latter effect could be achieved by stabilization of the γ1 phase or development of a system that would form the stable β1 phase during amalgamation.

Very low quality: We are very uncertain about the estimate. data in the downloaded RevMan file are editable and therefore the review data can be amended without warning. In order to trace the causes of failure in each case, the reasons for failure were classified according to a system described by Letzel et al in 1988. There were 5 materials in consideration and each tooth was randomized to 1 of them but it is not really clear which is the real number of restoration per participants, Location of teeth filled: 108 permanent molars and 124 premolars, Failures of restorations estimated at year 3, The 4 materials within each series were distributed at random over the teeth selected for restoration and the participants were assigned at random to 1 of 3 operators. Lambrechts P, Vanherle G, Vuylsteke M, Davidson CL. The US Food and Drug Administration warned Thursday that silver dental fillings, known as dental amalgam, may cause health problems for some high-risk groups. Such a system would simultaneously improve clinical performance and reduce the potential for biological side-effects from its deterioration. Evaluation every 6 months, Rate of replacement and repair of the restorations, psychosocial function (5‐year follow‐up), physical development (5‐year follow‐up), Sample size calculation: not reported. However, the BASC‐SR was developed for children ≥ 8 years.
the result of the decision‐making process of the operator), Type 3 ‐ failures caused by external factors, 12 centers were involved in the trial but the data of only 10 centers were used in this study because they complied with the condition of fully reviewing the restorations after at least 4 years, The authors declared that randomization was done in 5 of the centers, but there is no explanation about if the sequence generation had been at random in the other centers, There is no clarification in the paper about allocation concealment; however, due to the design of the study (split‐mouth), a lack of allocation concealment was unlikely to introduce bias, The follow‐up at 4 years was 76% for composite restorations. Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate. Mercury pollution is widespread and a global concern that originates from many diverse sources such as air deposition from municipal and industrial incinerators and combustion of fossil fuels.

This system was designed for an evaluation of the influence of experimental variables and operators on the survival rate of restorations included in controlled clinical trials of dental amalgams The system distinguishes 3 types of restoration failure: Type 1 ‐ failures directly related to the restoration (i.e.
