Importance of Chewing Simulators in the Difference of Test Results of
Dental Materials. Systematic Review
Abstract
Objectives: With new dental materials constantly being launched on the
market, the number of researches on the properties of dental materials
have increased substantially in the past few years. However different
results about physical properties of the same material are frequently
found in the literature. In an endeavor to elucidate the cause(s) of
these disparate results, a review of the literature published in the
last five years was conducted, to investigate whether these differences
are due to the testing machines - also called chewing simulators – used
in the studies. Data: We searched for data of indicators of test
accuracy, maintenance of test parameters during all experiments,
reproducibility of test and standards in the articles, or in the
manufacturers’ sites. Sources: The database searched was CAPES PORTAL
(http://www-periodicos-capes-gov-br.ez27.periodicos.capes.gov.br) Study
Selection: In the search, the following keywords were used: “bite
force” AND “simulator”, “chewing simulator” and “mastication
simulator”, and the publication filter date of “January 1, 2016”. As
a result, 100 articles were selected and recovered in order of
appearance by using the filter “relevance”. Conclusion: based on the
data obtained in this review, the disparate results of experiments with
dental materials appeared to be more related to the test conditions
rather than with the testing machines.
