The periapical radiograph demonstrated that the root apex of the tooth was adjacent to the mental foramen (Figure 1A). The CBCT scan revealed that the root apex was situated exactly on the mental foramen (Figure 1B).

Then, as demonstrated in Figures 2A and 2B, the tooth was carefully extracted through the use of forceps (Juya, Tehran, Iran). Under the dental operating microscope (DOM), 3 mm of the root was resected and evaluated for any cracks, fractures, or missed canals (Figure 2C). Subsequently, the canal was dried utilizing paper points (AriaDent, Tehran, Iran) and mineral trioxide aggregate (MTA) (Angelus, Londrina, PR, Brazil) was used as the retro filling material (Figure 2D). During this procedure, the tooth was held in forceps throughout the procedure, the extracted tooth were kept with a moist gauze (Figure 2A).
