Conclusion and Results (Outcome and follow-up)
The patient was followed up for six months post-intervention, with no signs of recurrence or complications. The patient reported significant relief from symptoms two days after retreatment. Follow-up radiograph at six months showed healed apical lesions (Figure 3B), and by the nine-month follow-up, there was complete resolution of the sinus tracts in the oral cavity (Figure 3C).
Photographs taken from the buccal and palatal views in the pre-operative session, 6-month and 9-month follow-up also show signs of healing of the fistulas (Figure 4). <Figures 3 & 4>
