“…When dentin is frankly exposed its relative structural weakness and high organic content result in a type of wear that is different from that of enamel 53 . A clear delineation appears at the border between dentin and enamel because the softer dentin wears down more quickly and these dentin areas assume a concave form and yellowish brown coloration.…”

Dental wear is deterioration as a result of use. It has existed since the beginning of mankind in all civilizations and cultures. It occurred routinely and intensely in early populations but was considered to be a physiological process. Ideas about dental wear are not as clear today because while it is less pronounced it sometimes appears in pathological patterns. Moreover, it is produced by many complex mechanisms acting in synchrony or sequentially, in synergy or additive, in patterns that often mask its true origins. In an effort to ameliorate the means of preventing and diagnosing dental wear and improving our understanding of its diverse manifestations, the primary objective of this article will be to present the principal mechanisms that produce it as well as their consequences. To organize our presentation we have adopted a tribological approach, focusing on the friction, wear, and lubrication of interacting surfaces.

“…This correlation is very complicated as there are no standards for some mechanical characterization of these composites, namely for abrasion tests [1]. There are a large number of variables involved in the in vitro studies, and the type of tests used in experimental approach varies greatly from investigating team [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. To understand the multiplicity of approaches about the subject, a summary of the most important variables was done.…”

“…Among the published studies, large differences can be observed on the contact conditions, counterface material and abrasive agent [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Concerning the antagonist material, steels [2,6,7,14,16,17] and enamel [1,[3][4][5]8] are the most tested ones.…”

“…Concerning the antagonist material, steels [2,6,7,14,16,17] and enamel [1,[3][4][5]8] are the most tested ones. However, some studies use polymers [9,18] or ceramics [10,13] and one of them uses titanium as antagonist [15]. The existence or non-existence of abrasive particles on the contact is another parameter that varies in the tests.…”

“…Knowing the wear resistance of the material in study is a key factor in materials development, but it is also very important to know how and how much the composite wears the antagonist material, natural tooth, restorative or prosthetic material. In the gathered studies only five of them evaluate the antagonist wear [1,3,4,14,15].…”

Resin composites were first introduced as anterior restorative materials, but are more and more used in posterior teeth, as amalgam replacements. Nowadays the so-called 'condensable' composites are frequently used in posterior teeth. These materials are subjected to high values of contact and mastigatory loads, loading rates and sliding distances. In such contact conditions, wear is the major failure mode of dental composites. Wear of dental composites includes such diverse phenomena as adhesion, abrasion and fatigue. These mechanisms may operate either alone or in combination.Most of the performed studies involve commercial composite materials and focus on the effect of curing time, and their reflection on the abrasive wear behavior. The wear compatibility of both materials in contact should be one of the concerns of the wear studies. However, the majority of studies do not consider the wear produced on the antagonist material. The present study aims to the understanding of the behavior of commercial composites under reciprocating contact. For the tests, a glass ball was used as opponent. At the end of each test, the wear volume was calculated on both contact materials: the composite and the glass counterface. The removal mechanisms involved in the wear process were discussed taking into account SEM observations of the contact surfaces.

For the development of new dental restorative materials, it is essential to evaluate and understand the structure -property relationships of the human tooth. This chapter fi rst discusses microstructure -property correlation of three major structural parts of the human tooth: enamel; dentin; and the dentin -enamel junction ( DEJ ). To evaluate the tribological properties of the human tooth, fretting wear test results will be discussed to illustrate how the wear of teeth is dominated by fretting fatigue and adhesive wear. Tooth wear involves the formation of the oxidized calcium phosphate based compounds and their subsequent transfer from tooth to alumina surface.In the context of dental restorative materials, various glass -ceramic (GC) materials are being developed. Considering the potential of the mica -based GCs as dental implants, an understanding of their wear behavior in the oral environment is important. The later part of this chapter discusses studies on K 2 O -B 2 O 3 -Al 2 O 3 -SiO 2 -MgO -F glass -ceramics containing about 70% crystals, heat -treated at 1040 ° C for 12 hours and subjected to fretting against a steel ball in an artifi cial saliva ( AS ) environment. It will be shown that the tribochemical layer formed in AS medium undergoes brittle fracture, whereas mica crystal pullout was the dominant mechanism in dry conditions.
