<p>Metals and alloys tend to degrade with time due to various factors leading to corrosion. Despite this, these alloys are used in multiple applications including the one with human implantation, among which dental alloys tend to be more prone to corrosion due to their constant interaction with varying pH, temperature, and external additives. The current study uses the leaves of <i>Citrus limon</i> as a corrosion inhibitor examining under varying concentrations and temperatures. The preliminary Physicochemical analysis of the leaf sample followed by the Qualitative phytochemical analysis for aqueous, acetone, and ethanolic extracts was conducted. The total content of flavonoids and phenols was estimated and maximum compounds were found soluble in ethanol extract which was then proceeded for HPLC analysis. The extracts were subjected to dental alloy as a green inhibitor with temperatures and concentration-dependent at 50–150˚C with 50-100ppm concentration against P-Ti and Gr5-Ti with maximum percentage efficiencies of 68%, 71.1%, and 59.8%, 62.0% for Potentiodynamic Polarisation (PDP) and Electrochemical Impedance Spectroscopy (EIS) plots respectively. An increase in inhibition was noticed with increase in concentrations which is due to the phytochemicals such as hesperidin, naringin etc. Further, the Antioxidant activity was evaluated using DPPH and H₂O₂ assays which reduces the oxidative stress and the anti-inflammatory activity was estimated using Bovine Serum albumin (BSA) and Egg albumin denaturation assays which depicted the free radical and protein denaturation properties of the extract respectively. The study uses <i>Citrus limon</i> leaf extract as green inhibitor for the very first time to enhance the overall efficiency of dental alloys. This work not only enhances the protection of the dental alloys but also provides free radical scavenging and protein denaturation properties that enhances the overall experience of the alloy.</p>
