Tissue engineering therapy in dentistry now utilizes bio-absorbable scaffolds. By scanning electron microscopy (SEM), we observed structures of three commercial scaffold sponges made of collagen, poly-lactide and calcium phosphate for 3-dimensional (3D) cell culture and one commercial porous bio-absorbable tri-calcium phosphate block for bone-defect filling. It became clear that four samples had pores which ranged widely from approximately 100 to 650 mm and the pores were interconnected both in parallel and perpendicular directions.
