“…This solution was chosen on one side since it is frequently used in previous research work [1,5,30,31], but also because it generates a similar electrochemical behavior of metallic materials as observed in human saliva [32]. NaF was added to the Fusayama's stock solution to reproduce F -concentrations found in the oral cavity.…”

“…Concerning the corrosion behavior of dental materials, the properties of several artificial saliva solutions were reported in literature [47-49, 51, 52]. However, some previous studies [51,52] reported that the corrosion behavior of dental materials in artificial saliva proposed by Fusayama [53] was most closely approximating the one in natural saliva. Nevertheless, other formulations have also been reported as most appropriate for studying corrosion of dental materials [49].…”

The oral cavity is a complex environment where corrosive substances from dietary, human saliva, and oral biofilms may accumulate in retentive areas of dental implant systems and prostheses promoting corrosion at their surfaces. Additionally, during mastication, micromovements may occur between prosthetic joints causing a relative motion between contacting surfaces, leading to wear. Both processes (wear and corrosion) result in a biotribocorrosion system once that occurs in contact with biological tissues and fluids. This review paper is focused on the aspects related to the corrosion and wear behavior of titanium-based structures in the oral environment. Furthermore, the clinical relevance of the oral environment is focused on the harmful effect that acidic substances and biofilms, formed in human saliva, may have on titanium surfaces. In fact, a progressive degradation of titanium by wear and corrosion (tribocorrosion) mechanisms can take place affecting the performance of titanium-based implant and prostheses. Also, the formation of wear debris and metallic ions due to the tribocorrosion phenomena can become toxic for human tissues. This review gathers knowledge from areas like materials sciences, microbiology, and dentistry contributing to a better understanding of bio-tribocorrosion processes in the oral environment.

“…Contamination from other polymer-based materials and plastics was prevented by avoiding the use of gloves. Artificial saliva was composed of NaCl ) and distilled water (1,000 mL), at a neutral pH, as previously described 14) . At each sampling point (1, 24 and 72 h), the extraction media were removed and transferred to new vials for HPLC analysis.…”

The aim of this study was to evaluate the amount of leached residual monomers from self-adhesive resin cements and evaluate their toxicity in-vitro. A total of 60 disk-shaped specimens (5 mm in diameter and 0.5 mm in thickness) were prepared from each cement (RelyX U200, SpeedCEM, G-Cem) (n=20). Specimens were immersed in artificial saliva and the amount of released monomers [urethane dimethacrylate (UDMA) and triethyleneglycol dimethacrylate (TEGDMA)] was identified. Then, the cytotoxicity and genotoxicity effect on cells were evaluated using the defined amounts of released monomers from cements. The highest monomer release was detected in G-Cem (p<0.05). The highest cytotoxicity value was identified from SpeedCEM (p<0.01) and the highest genotoxicity values were calculated from RelyX U200 (p<0.05). Released UDMA and TEGDMA from self-adhesive resin cements induced cytotoxicity and genotoxicity effect on cells.
