Application Status of Hydrogel Scaffold Materials in Dental Pulp Regeneration
Pulpitis and periapical diseases are common oral diseases,and the commonly used treatment method is root canal therapy.However,it is difficult to restore the structure and function of the dental pulp,and after root canal therapy the teeth will become brittle,discolored,and be prone to tooth fracture and/or reinfection due to microleakage.Pulp regeneration tissue engineering technology is currently one of the effective methods to solve the complications of root canal therapy.Among them,the scaffold is one of the three elements of tissue engineering,and its performance directly affects the effect of tissue regeneration.Among many scaffolds materials,hydrogel is widely used in dental pulp regeneration due to its biocompatibility,certain mechanical toughness,degradability and rheological properties.Hydrogels have shown unique advantages in drug delivery and pulp regeneration.This article reviews the application status of hydrogel scaffolds in dental pulp regeneration in recent years.
