“…This is why, the implementation of more clinical and laboratory studies for the detection of any adverse effects of titanium's particles on the body's cells is highly suggested. [17] Royhman et al [18] evaluated the corrosion effect of nicotine on Ti-6Al-4V under physiological conditions. It was hypothesized that nicotine in artificial saliva would have an adverse side effect on the corrosion of Ti-6Al-4V.…”

“…This research may assist in formulating strategies to improve dental implant success and survival rates in patients, who consume nicotine products routinely. [18] Flatebo et al [19] demonstrated the presence of corrosion titanium particles in the tissue adjacent to Ti cover screws. However, Ti particles may be released during insertion of the fixture and may be retained in the covering soft tissue.…”

Corrosion of implant components, including that of cover screws, has been reported as a possible etiological factor for implant failure. This study evaluated the presence of metallic particles in the soft tissues overlying two-stage implants after placing cover screws, by using a histological technique and energy-dispersive X-ray spectroscopy. The results showed large and small titanium particles in different layers of the soft tissue overlying the implant and cover screws in the majority of samples, with more particles near the cover screws. These particles might have contributed to the various degrees of inflammatory reactions detected in the different layers of the overlying soft tissues. Further studies on the corrosion of implants' metallic components are recommended, so that the implant failure rates could be minimized.

“…Furthermore, it was proven that infection, the presence of nicotine and soft drinks with varying pH levels might impose challenges on the implant surfaces by shifting the normal potential to very anodic values. 25,42,43 It can be noted that 1-CaP10 and 1-CaPAg10 had their potentiodynamic curves shifted to the upper-left region of the graph, demonstrating nobler potential and lower current compared to other groups.…”

Biofunctionalized surfaces for implants are currently receiving much attention in the health care sector. Our aims were (1) to create bioactive Ti-coatings doped with Ca, P, Si, and Ag produced by microarc oxidation (MAO) to improve the surface properties of biomedical implants, (2) to investigate the TiO2 layer stability under wear and corrosion, and (3) to evaluate human mesenchymal stem cells (hMSCs) responses cultured on the modified surfaces. Tribocorrosion and cell experiments were performed following the MAO treatment. Samples were divided as a function of different Ca/P concentrations and treatment duration. Higher Ca concentration produced larger porous and harder coatings compared to the untreated group (p < 0.001), due to the presence of rutile structure. Free potentials experiments showed lower drops (-0.6 V) and higher coating lifetime during sliding for higher Ca concentration, whereas lower concentrations presented similar drops (-0.8 V) compared to an untreated group wherein the drop occurred immediately after the sliding started. MAO-treated surfaces improved the matrix formation and osteogenic gene expression levels of hMSCs. Higher Ca/P ratios and the addition of Ag nanoparticles into the oxide layer presented better surface properties, tribocorrosive behavior, and cell responses. MAO is a promising technique to enhance the biological, chemical, and mechanical properties of dental implant surfaces.

“…Findings revealed that the corrosion rate of titanium decreased with a increase in nicotine concentration. However, the presence of nicotine also negatively affected the passive film formation, being that the passive current density and polarization resistance were reduced, leading to the worst overall surface performance [63].…”

The main aim of this work was to perform a comprehensive review of findings reported by previous studies on the corrosion of titanium dental implants and consequent clinical detrimental effects to the patients. Most studies were performed by in vitro electrochemical tests and complemented with microscopic techniques to evaluate the corrosion behavior of the protective passive oxide film layer, namely TiO2. Results revealed that bacterial accumulation, dietary, inflammation, infection, and therapeutic solutions decrease the pH of the oral environment leading to the corrosion of titanium. Some therapeutic products used as mouthwash negatively affect the corrosion behavior of the titanium oxide film and promote changes on the implant surface. In addition, toothpaste and bleaching agents, can amplify the chemical reactivity of titanium since fluor ions interacting with the titanium oxide film. Furthermore, the number of in vivo studies is limited although corrosion signs have been found in retrieved implants. Histological evaluation revealed titanium macro- and micro-scale particles on the peri-implant tissues. As a consequence, progressive damage of the dental implants and the evolution of inflammatory reactions depend on the size, chemical composition, and concentration of submicron- and nanoparticles in the surrounding tissues and internalized by the cells. In fact, the damage of the implant surfaces results in the loss of material that compromises the implant surfaces, implant-abutment connections, and the interaction with soft tissues. The corrosion can be an initial trigger point for the development of biological or mechanical failures in dental implants.

Abstract: At certain concentrations, nicotine inhibits local corrosion; however, it also prevents the formation of a protective oxide film.
