Purpose: To determine the effects of the microgroove-fibronectin complex surface on the expression of various genes related to cellularactivity in human gingival fibroblasts.

Materials and Methods: Smooth titanium specimens (NE0), acid-treated titanium specimens(E0), microgroove and acid-treated titanium specimens (E60/10), fibronectin-fixed smooth titanium specimens (NE0FN), acidtreatedand fibronectin-immobilized titanium specimens (E0FN), and microgroove and acid-treated titanium specimens immobilizedwith fibronectin (E60/10FN) were prepared. Real-time polymerase chain reaction experiments were conducted on 44 genes relatedto cell behavior of human gingival fibroblasts.

Results: Adhesion and proliferation of human gingival fibroblast on microgroovefibronectincomplex titanium were activated through four types of signaling pathway. Integrin ¥á5, Integrin ¥â1, Integrin ¥â3, Talin-2,which belong to the focal adhesion pathway, AKT1, AKT2, NF-¥êB, which belong to the PI3K-AKT signaling pathway, MEK2, ERK1,ERK2, which belong to the MAPK signaling pathway, and Cyclin D1, CDK4, CDK6 genes belonging to the cell cycle signaling pathwaywere upregulated on the microgroove-fibronectin complex titanium surface (E60/10FN).

Conclusion: The microgroove-fibronectincomplex titanium surface can up-regulate various genes involved in cell behavior.
