Tracing was done by using the periapical radiograph in the first appointment, radiolucency at the fracture line and resorption of the apical part of the coronal segment of tooth #8 can also be seen in this radiograph

The tracing radiograph showed the tip of the gutta-percha cone extending up to the fracture line (Figure 1). According to evaluations tooth #8 was necrotic and infected; thus an access cavity was prepared and the estimated working length of coronal fragment was determined using the periapical radiograph (Figure 1).
Post-surgical radiograph showing the canal was sealed using mineral trioxide aggregate (MTA) and a thin layer of light-cure glass ionomer was placed on the MTA and the access cavity was restored using composite resin

A thin layer of light-cure glass ionomer (Fuji, GC Corp., Tokyo, Japan) was placed on the MTA and the access cavity was restored using composite resin (Stellite, Japan) (Figure 2).
Follow-up radiographs are shown in figures A to E for 6, 12, 18, 24 and 36 months, respectively, on which we can see complete bone healing, ceasing of the resorbing of the apical part of the coronal segment of tooth #8, and lack of degenerative changes in periapical bone and the structure of tooth #9

Both teeth #8 and #9 were followed up clinically and radiographically for 6, 12, 18, 24 and 36 months. complete bone healing, stop resorbing of the apical part of the coronal segment of tooth #8 and the lack of degenerative changes in periapical bone and the structure of tooth #9 root were seen in the follow up radiographs (Figure 3).
