Periapical radiographic image: Notice the curved blade elevator tip broken and embedded in a subgingival caries cavity of the mandibular left second molar (37). Observe two radiolucent apical lesions in the affected molar (37) and a slight radiopacity located on the distal part of the first molar crown (36), which was a consequence of the Kocher clamp used during a manual developing process.
