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

AMAldilla Miranda IKIra KOMARA ACArief Cahyanto

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.

Abstract

Both 15 kGy and 25 kGy significantly altered surface properties, but 25 kGy induced greater Ti ion release and micro-damage. Within the study limitations, 15 kGy is recommended as the preferred sterilization dose, as it maintains sterility while minimizing mechanical degradation and excessive Ti ion release as compared to 25 kGy.
