“…An extensive knowledge of the mechanical behavior of composites is required to know which are property-enhancing without damaging other properties. Within this context, the application of the "tribology" concept to research on composite dental materials can be extremely useful for a better understanding of the mechanical behavior of composites [51,52]. The application of tribology in the dental field is justified by the fact that the oral cavity is comparable to a tribological system.…”

“…The application of tribology in the dental field is justified by the fact that the oral cavity is comparable to a tribological system. The relative motion between teeth and restorative materials in the presence of saliva and external components such as food and drink results in contact and subsequent wear of teeth and restorative materials [6,51]. Understanding the tribological mechanisms underlying tooth wear is important to minimize dental resin damage and promote efficient development of new biomaterials.…”

“…Although the most reliable way to determine the clinical performance of dental composites would be to conduct in vivo testing, some methodological limitations make them inadequate for providing standardized and replicable results [51]. Consequently, in vitro testing is much more used in research and results are more informative because of the precise control of variables involved [51].…”

Tribology is the discipline concerning the application of friction, lubrication, and wear concepts of interacting surfaces in relative motion. A growing interest has developed in tribology application in medical biomaterials, such as resin composites used in restorative dentistry. Yet, the keywords “tribology” and “biotribology” are little applied in the pertinent publications. The aim of this scoping review was to offer an overview of tribology application in dental composites research and to identify knowledge gaps and address future research. A literature search was conducted on Pubmed and Scopus databases and the studies investigating the tribological behavior of resin composites were included for qualitative synthesis. The majority of studies on dental tribology were published in the research areas of mechanical engineering/nanotechnology and differed in several methodological aspects. The preponderant engineering approach and the lack of standardized testing make the laboratory findings poorly informative for clinicians. Future research should focus on the tribological behavior of dental materials composites by means of an integrated approach, i.e., engineering and clinical, for improving development and advancement in this field of research.

“…The loss of dental structure due to caries, trauma, cavity preparation, and endodontic treatment has a negative impact on tooth fracture resistance [1][2][3]. The commonly proposed functional reconstructions for premolars with extensive structure reduction have been the direct adhesive techniques, using composite resins due to the high adhesion capacity to the dental structures [4] and to seek minimal dental damage during the repair preparations [5]. Other types of treatments, generally less conservative, are available to treat posterior teeth using indirect treatments, nowadays generally performed with CAD/CAM technology [6,7].…”

This study applied the finite element method (FEM) and the moiré strip projection method to evaluate the biomechanical behavior of healthy and endodontic-treated premolar teeth. The finite element method and the moiré strip projection method were applied to evaluate the influence of restored materials in association with cervical lesions and were considered as strain estimates for a tooth sample with 21 units, under loads of 25, 50, 75, and 100 N, frontal and oblique applied. The focused cases were: tooth H healthy; tooth A-MOD amalgam; tooth AL-MOD amalgam + lesion; tooth ALR-MOD amalgam + injury restored; tooth R-MOD resin; tooth RL-MOD resin + lesion; tooth RLR-MOD resin + injury restored. The results obtained by FEM simulation can be considered perfectly validated by the results presented by the experimental moiré projection analysis, demonstrating that the FEM numerical analysis can be used to evaluate the biomechanical behavior of healthy and endodontically treated teeth. Developing an alternative protocol to generate FEM three-dimensional models will lead to a ready and inexpensive tool since there is no need for costly equipment for tooth extraction prognosis.

“…Among those devices, prosthetic restorations are subject to fretting corrosion and wear [12][13][14], and the released wear debris may produce ionic species which have a potential toxicity depending on their concentration [15]. Consequently, it is of utmost importance to analyze the behavior of those ions in the oral cavity.…”

Metal ions such as cobalt (II) and chromium (III) might be present in the oral cavity, as a consequence of the corrosion of Co-Cr dental alloys. The diffusion of such metal ions into the organism, carried by saliva, can cause health problems as a consequence of their toxicity, enhanced by a cumulative effect in the body. The effect of the chlorhexidine digluconate, which is commonly used in mouthwash formulations, on the transport of these salts is evaluated in this paper by using the Taylor dispersion technique, which will allow an assessment of how the presence of chlorhexidine digluconate (either in aqueous solution or in a commercial formulation) may affect the diffusion of metal ions. The ternary mutual diffusion coefficients of metal ions (Co and Cr) in the presence of chlorhexidine digluconate, in an artificial saliva media, were measured. Significant coupled diffusion of CoCl2 (and CrCl3) and chlorhexidine digluconate is observed by analysis of the non-zero values of the cross-diffusion coefficients, D12 and D21. The observed interactions between metal ions and chlorhexidine digluconate suggest that the latter might be considered as an advantageous therapeutic agent, once they contribute to the reduction of the concentration of those ions inside the mouth.
