Abstract
INTRODUCTION: Throughout history many kinds of different suture materials have been used for closing and suturing surgical wounds. Medical literature describes four basic characteristics of suture material: knot safety, tensile strength, tissue reaction and wound safety. The tissue reaction is reflec...

Abstract
We found that the degradation of aqueous based silk is much faster than HFIP based silk scaffolds. Also, HFIP based silk scaffolds supported the soft dental pulp formation better than the aqueous based silk scaffolds. No distinct hard tissue regeneration was found in any of the implants, with or wit...
