Bionic dental pulp: its potential value following root canal therapy.

Dental pulp can provide nutrition for teeth. The teeth after root canal therapy without pulp will turn frailer because of dehydration, and it may be easily broken. Bionic dental pulp possesses similar components of the healthy dental pulp. So we put forward a hypothesis that bionic dental pulp can be filled into root canals to provide nutrition for teeth like healthy pulp. Then the life-span of teeth after root canal therapy could increase.
