Control radiograph showed three root fillings continuous with the retrograde fillings and one retrograde root filling in the unfilled mesiopalatal canal. Notice the depth of the retrograde filling in the MP canal. Shorter fillings can easily jeopardise long term prognosis because of leakage from the root canal.

It should be emphasised that intentional replantation includes risks of later root resorption and should not be used as a routine method for periapical surgery.
