“…Structure, hardness, roughness behavior and bacterial adhesion of Co-Cr based alloy changed after aging in saliva for different interval times [9]. Compared between the corrosion behavior of Cr-Co and Cr-Ni alloys in distilled water, orange nectar, cola and artificial saliva [10]. The corrosion process of Ni-Cr-Mo alloys in acidic artificial saliva with pH 5 at 37 °C is studied [11].…”

Aging in normal saliva for different interval times make a change in internal structure (Formed phases and started base line) of Sliver- Palladium (Ag-Pd) dental alloy. Also aging in saliva for one, two and three weeks decreased Vickers hardness value, calculated maximum shear stress (τm) and roughness parameters for Sliver- Palladium alloy. Microbiological studies show the Candida spp. stuck on Sliver- Palladium alloy surface and their growth dependent on aging times.

“…When the allergic antigen is a metal ion, primary irritation responses occur readily, and it is often difficult to distinguish irritation from allergic reactions. In the case of type IV hypersensitivity, patch tests are usually used to determine the allergen, and are considered the gold standard in the diagnosis of type IV hypersensitivity reactions ( 6 ). Studies have shown that the levels of HLA-DR expression allows the identification of patients with clinical marginal rejection.…”

The present study aimed to provide guidance for the selection of prosthodontic materials and the management of patients with a suspected metal allergy. This included a comparison of the sensitivity of patients to alloys used in prescribed metal-containing prostheses, and correlation analysis between metal allergy and accompanying clinical symptoms of sensitized patients using a patch test. The results from the patch test and metal component analyses were processed to reach a final diagnosis. In the present study, four dental alloys were assessed. Subsequent to polishing the surface of a metal restoration, the components were analyzed using an X-ray fluorescence microscopy and spectrometry. Immunohistochemical analysis, reverse transcription-polymerase chain reaction and western blotting were used to detect the expression levels of human leukocyte antigen (HLA)-DR in gingival tissues affected by alloy restoration, and in normal gingival tissue samples. Positive allergens identified in the patch test were consistent with the components of the metal prostheses. The prevalence of nickel (Ni) allergy was highest (22.8%), and women were significantly more allergic to palladium and Ni than men (P<0.05). The protein and gene expression levels of HLA-DR in the Ni-chromium (Cr) prosthesis group were significantly higher, compared with those in the other groups (P<0.01); followed by cobalt-Cr alloy, gold alloy and titanium alloy. In conclusion, dentists require an understanding of the corrosion and allergy rates of prescribed alloys, in order to reduce the risk of allergic reactions. Patch testing for hypersensitive patients is recommended and caution is required when planning to use different alloys in the mouth.
