Abstract

Aim
Is to assess Hyaluronic acid as scaffold for regenerative endodontic procedures (REPs).

Methodology
A sample of 30 patients have been chosen randomly from Endodontic department of faculty of Dentistry Ain shams University, and divided randomly into 2 groups (15 patients in each one) (n=15). The 2groups were treated with classic protocol of ERT (acc. To AAE considerations) by blood clot formation (B.C), but the second one was received additional step which is injecting a scaffold using cross-linked injectable Hyaluronic acid gel as scaffold.



Results
The percentage of difference in tooth length, root thickness, apical diameter between the 2 groups were statistically analysed by calculating Mean and standard deviation. The significance level was set at P Difference in percentage of root length change bett. 2groups P=0.963
Difference in percentage of root thickness change bett. 2groups P=0.035
Difference in percentage of apex diameter change bett .2groups P=0.035

Conclusion
Cross linked Hyaluronic acid can be used as a scaffold in REPs.
