Abstract

The purpose of this vitro study was to evaluate the activity of human pulpal cells to adhesive glycoprotein-coated and non-coated culture dishes. Well known adhesive glycoproteins were used, such as type I collagen, type IV collagen, fibronectin, laminin, and vitronectin. Each adhesive glycoproteins applied onto the culture dishes. In this study, the protein coated and non-coated dishes were classified as each groups. Human pulpal cells cultured onto each groups. After 24 hours, 48 hours, 72 hours incubation time, radioactivity with scintillation counter for evaluation of the activity of human pulpal cells. The results as follows : 1. After 24 hours incubation time, activity of human pulpal cells were best in laminin-coated group among groups. Then fibronectin, type I collagen group were better, and all proteins were better than control. 2. After 48 hours incubation time, activity of human pulpal cells were best in fibronectin coated group. 3. After 72 hours incubation time, activity of human pulpal cells were not significantly different in all of adhesive glycoproteins. 4. After 24 hours incubation time, activity of human pulpal cells were best in fibronectin and laminin coated group. Activity of human pulpal cells in type I collagen coated group were better after 24 hours incubation time then 48 hours incubation time.
