Introduction Titanium is a very reactive metal, although its passive oxide film makes it resistant to corrosion even in an acidic environment. Fluoride (F (-)) is used as dental caries prophylaxis agent in toothpastes and mouthrinse. It is one of the few mediators that can damage or disturb protective titanium oxide layer, thus reducing resistance to corrosion. Titanium corrosion or ion migration to soft tissue has a crucial impact on peri-implantitis pathogenesis or development of titanium allergy. Therefore is it very important to understand what factors influence negative fluoride impact. Aim To analyse the influence of fluoride and its concentration and pH level of the substance on titanium and its alloys corrosion resistance in scientific literature. To overview recommendations on use of prophylaxis products containing fluoride. Methods Search was performed using the PubMed database and PRISMA selection criteria was applied. In the initial stage keywords were used as follows: “fluoride”, “titanium”, “titanium implants”, “titanium corrosion”. Then a search filter of publication from 2015 to 2020 was applied. 358 results were found. The consistent study of search results was conducted to estimate their eligibility. Inclusion criteria: English language, published in 2015-2020, studies analysing influence of fluoride and its concentration and pH level of the substance on titanium and its alloys corrosion resistance. Exclusion criteria: case reports, systematic, meta-analysis and pilot studies. Finally, 11 articles were selected for analysis. Results 11 articles were screened, which examined fluoride concentration and pH level influence on titanium and its alloys corrosion in vitro. 11 research states that titanium and its alloys corrosion resistance decreases when fluoride concentration increases. Titanium ion elution and surface colour change was noticed when 9000ppm NaF solution was used. [...].
