Confusing MB2 (by Ilya Mer)

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.

Preoperative X-ray. Premolar has a decent obturation but PDL slightly wide Visible black line of missed MB2 is seen in MB of the first molar

Visible black line of missed MB2 is seen in MB of the first molar in the coronal third
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.

The decision has been changed and apico was done on both roots MB of molar and the single root of premolar
