A Pre Opertative X-Ray show a large lesion with very bad old treatment

Starting of the procedure with rubber dam 

Removing all caries and old materials before start the cleaning and shapping of the canals 

Fig. 3

Build up the missing wall before start to make sure that all irrigation will be saved 

In the box of the access cavity 

Here we do not need to make perfect contact point because the tooth prepare for a crown 

Just rewalling the missed wall

Start to remove old obturation in the mesial root and reach the apex 

Fig. 5

After cleaning the isthmus between the mesial canals and catching the middle mesial canal

Fig. 6

We notice that MMC were joined with the mesiobuccal canal and detected 

Very deep split in the distal root

After obturation by WVC technique  and cleaning the access cavity

Post op X-Ray


The anatomy is very important and we have to study the case very well 

CBCT can help us to detect secondary canals like MMC with the using of 

Magnification and illumination
