| Outline of Final Research Achievements |
To examine the effects of diamond like carbon coating containing different level of hydrogen (ta-C(H) DLC), on the differentiation of osteoblastic cells and osteoclastic cells in vitro. In addition, antimicrobial activity of ta-C(H) DLC was also examined.
Real-time quantitative reverse transcriptional polymerase chain reaction analysis revealed that ta-C(H) DLC promoted the expression of Runx 2, Osterix and ALP of MC3T3-E1 cells, as compared with those of untreated titanium. On the other hand, ta-C(H) DLC suppressed the expression of TRAP and cathepsin K mRNA in RAW264.7 cells, as compared with those of untreated titanium. Further, ta-C(H) DLC exhibited the inhibitory effect against P. gigivalis biofilm formation, as compared with that on untreated titanium. These results, taken together, suggested that ta-C(H) DLC is one of the most preferable avenue to obtain the acquisition of osseo-integration.
