The palatal roots had two orifices, fairly well separated, exiting from the floor of the pulp chamber (Figures 1 and 2).

The working length of each canal was estimated by means of an apex locator (Ray Pex 5, VDW Gmbh, Germany) and confirmed with intra oral periapical X-ray (Figure 3).The canals were initially instrumented with stainless steel K files (n 10/15) under irrigation with 3% sodium hypochlorite.

Mesiobuccal and distobuccal canals were shaped by the crown down technique using a 35 master apical file for mesiobuccal (MB) and a 40 for distobuccal (DB). Master cone radiograph was taken (Figure 4).

Obturation of root canal space was performed with gutta-percha (Dentsply, Maillefer, Switzerland)) and AH plus resin sealer (Dentsply DeTrey Gmbh, Germany) (Figure 5) using a lateral condensation technique and the tooth was restored with a posterior composite filling P60 (3M FiltekTM, USA).
