case_images: Cervical spine MRI was normal and brain MRI showed chronic sinusitis (Figure 1).
case_images: Orthopantomogram before treatment showed the upper left second molar opened with periapical radiolucency.

case_images: Radiograph examination in orthopantomogram and periapical (Figures 2 and 3) showed radiolucency around upper 6 and 7 and arrived at the border of the maxillary sinus using rubber dam for isolation starting with using a cold and percussion test to determine the vitality of pulp, upper 6 positive on cold but there is no pain on percussion and upper 7 pain on percussion but negative on cold.

case_images: Our initial diagnosis was upper left second molar previously initiated therapy with chronic apical abscess with sinus tract; the upper left first molar was diagnosed with irreversible pulpitis; normal apical tissues used gutta-percha to determine the caused tooth of sinus track (Figures 4 and 5).

case_images: Irrigation with sodium hypochlorite was done, and then normal saline was used for final irrigation, canal was dried using F1 paper point, and calcium hydroxide with iodoform as an internal canal medication (Figure 6).
