A 25-year-old female patient came to the dental office with pain related to upper anteriors,history was taken and it turned out that she had trauma 5 years ago. 

Initial radiograph was taken then CBCT was requested .

B) CBCT image showing sagittal view of tooth 21 with an internal resorptive defect.

This figure shows some steps of therapy

A) initial radiograph revealed internal root resorption at apical part

B) taking working length and confirm it

C) MTA apical plug also you can notice manual plugger

D) shows MTA plug done .

MTA = mineral trioxide aggregate

Fig. 4

This figure shows the rest of therapy steps:

A and B: MTA plug

C: back filling of gutta-percha

D: final radiograph including permanent restoration.

intra oral picture shows complete isolation followed by secondary isolation & access cavity

step of introducing 15K file to size up the situation and working length .

Intra oral photo shows chemical debridement with sodium hypochlorite solution in the canal and the resorption lacuna

The root canal has been dried with sterile paper points

The MTA is placed with a dedicated carrier

The microscopic picture shows the first step of apical obturation with MTA

Subsequently the root canal is filled with warm gutta percha

The intra oral pictures show

A: access cavity

B: MTA plug

C: GP filling

A: Pre-operative radiograph

B: Post-operative radiograph

C: seven-months follow-up showing healing


Internal inflammatory root resorption is a particular pulpal disease, which can be diagnosed by clinical and radiographic examinations. Nowadays, the diagnosis of internal root resorption is significantly improved by the three-dimensional imaging as CBCT that provides superior diagnostic accuracy resulted in an improved management of the resorptive defects and a better outcome of conservative therapy.
