The following report describes a case of nonvital immature permanent tooth with foreign object impacted in the periapical region.
Treatment of nonvital immature permanent teeth can become complicated with the presence of foreign objects in the canal, which acts a continuous source of pain and infection. The chances of these objects getting impacted periapically increases in case of teeth with open apices. These objects can be easily retrieved if they are located within the pulp chamber but once the object has been pushed apically their retrieval may be complicated. Apical surgery may sometimes be necessary. The following report describes a case of nonvital immature permanent tooth with foreign object impacted in the periapical region. The treatment included retrieval of foreign object through periapical surgery followed by retrograde sealing with MTA. MTA has been advocated for use as an apical barrier because of its sealing capabilities, ability to set in the presence of moisture, its biocompatibility and ability to induce hard tissue formation.
12 month follow up of the case showed progressive healing clinically and reduction in the size of the periapical lesion.
