Abstract
This article discusses the development of a test bench and a methodology for the study of composite resin abrasive wear. To evaluate the operation of the test bench and to compare the proposed methodology with other existing ones, a study was made of the five composites most commonly used by dentists. The one-way ANOVA method and the Tukey test were used to statistically analyze the results by multiple comparisons of the groups of resins tested. Using the proposed methodology, these resins were classified in an increasing order of abrasive wear strength, as follows: Charisma (the lowest abrasive wear strength), Tetric, TPH, Herculite and Z-100 (the highest abrasive wear strength) (p < 0.05). In comparison to other methodologies, the results of the proposed methodology presented the lowest coefficient of variation.
Highlights
Composite resins were developed with the objective of replacing the loss of human dental material, be it by accident or as the result of dental surgery to improve a person’s living conditions
The tests were carried out making sure that the same pattern of physical actions were performed during all the experiments with the five composite resins, i.e., Charisma, Herculite, TPH, Tetric and Z-100
The analysis of the results of this study, their accuracy and repeatability, as well as the facility and the short period of time required to perform each test, allow the authors to conclude that the test bench proposed meets the initial requirements of ensuring a safe and fast method to analyze the abrasive wear of composite resins
Summary
Composite resins were developed with the objective of replacing the loss of human dental material, be it by accident or as the result of dental surgery to improve a person’s living conditions. Among the several existing materials that can be used for this purpose, composite resins were chosen because they are more wear resistant, easier to handle (they are sold in tubes like toothpaste), and because their coloring closely resembles that of human teeth, making them almost imperceptible after application. The main problem involved in the use of composites is their wear, which may result from brushing and mastication Studies of this phenomenon are needed in order to foresee the service life of composites, since they require substitution when they wear out
