Abstract

Purpose: The purpose of this study was to find the effect of ultraviolet (UV) radiation on the osteoblastic activity of polyether ether ketone (PEEK). Materials and methods: Thirty samples of PEEK discs were made. The samples were grouped as group I (n = 15) PEEK with no treatment and group II (n = 15) PEEK modified by UV radiation. The experimental group was seeded with human osteoblastic sarcoma cells. The samples were incubated for 48 hours at 37 ± 1°C in a humid atmosphere at 5%. After 48 hours, 2.5% glutaraldehyde was applied to fix the seeded cells to the coverslips. The discs were seen under scanning electron microscopy to evaluate the colony formation and adhesion of osteoblastic cells on the PEEK discs. The observation made was tabulated and subjected to statistical analysis. Results: Noticeable adhesion of osteoblast was found in the UV-treated PEEK samples when compared to PEEK samples with no treatment. The cells in nontreated PEEK samples were less spread and showed few colonies. PEEK modified by UV radiation showed more noticeable osteoblast cells scattered all around the sample. The adhesion of the cells was better as compared to group I. The difference between the test and control group was statistically significant when analyzed by Fisher's exact test. Conclusion: PEEK modified with UV radiation showed more noticeable osteoblast cells scattered all around the sample. The adhesion of the cells in UV-treated samples was better as compared to no treatment.
