Aim: To understand the effects of implant chemical treatment on the surface of two grades of Titanium. The solutions in this study are typically used in the clinical setting for implant sterilization. Methodology: Prior to treatment, disks of pure Ti (cpTi) and alloy (Ti14Al6V) were cut and polished. The surfaces were imaged with 3D microscopy (Keyence VHX 2000) and Atomic Force Microscopy (AFM Workshop). Treatment was performed with a series of compounds including citric acid, hydrogen peroxide, chlorhexidine‐gluconate, sodium fluoride, and several others. The treatments included both immersions in solution and rubbing with a cloth. pH was quantified before and after treatment with a pH meter (Metler Toledo). Results: Surface pitting was seen in both methods with solutions having pH蠄3 on both grades tested. Surface attack was more apparent with cpTi versus the same treatment preformed on the alloy. No significant change was seen with both methods in solutions with a pH>5. Oxidation was seen in both methods after treatment with cpTi in antibiotic treatments. AFM analysis further revealed pitting. Conclusion: Acidic environments coupled with rubbing were shown to cause oxidation of the surface of both Ti grades. These observations show that surface damage of dental alloys can be potentially induced prior to implantation. Additional studies will study particle dissociation due to treatments.
