RCT of the only premolar  was done because of pulp necrosis approximately 7 months before but still had tenderness to percussion and patient couldn’t bite on it sometimes.

The treatment plane was to try to negotiate the MB2 canal then make an apicoectomy on premolar and to scoop out extended guttapercha of MB root of the molarThe arrow points to MB2 orifice

I've been confused faceng resorcinol obliteration after necrotic MB2 negotiation. Two possible orifices were explored but I couldn't go through. The first visit ended up with to white lines close to perfs.
