Dose-dependent effects of gamma-ray irradiation on SLA-treated titanium Grade 4: An in vitro evaluation of its physical, chemical and surface properties

Key Points

• Surface properties of titanium are significantly altered by both 15 kGy and 25 kGy gamma-ray irradiation, with the latter causing more damage.
• The study demonstrates that 25 kGy leads to greater Ti ion release and micro-damage compared to 15 kGy.
• Assessment involved in vitro analysis of physical and chemical properties under varying irradiation doses.
• Choosing the appropriate dose is crucial; 15 kGy maintains sterility while limiting negative effects.
