After confirmation, rubber dam was applied and working length was determined using an apex locator and confirmed with a radiograph ( Figure 2). When a вЂњdropвЂќ into a space was felt, a #8 K-file was introduced and a radiograph taken to confirm entry. Care was taken to keep the file aligned to the long axis of the tooth to avoid perforation. The file was used with reaming motion and apical pressure. As an alternate method to gain further penetration in to the canal a 25 mm length #25 K-file was used by cutting 3 вЂ“ 4 mm of its tip with the help of an orthodontic wire cutter. On clinical examination and trials, it was difficult to locate an orifice with an endodontic explorer. The orientation of the access using high speed diamond bur was confirmed using radiographs to avoid perforation.Дue to unavailability of long shanked burs in our newly developed clinics, we were unable to go deeper and the radiograph showed around 3 вЂ“ 4 mm of calcified dentine remaining till the canal could be negotiated. Using this pigmented spot as a guideline, the tooth was entered using high-speed round No. On examination, a dark spot was seen on the floor which could have suggested the position of the canal orifice previously. The floor of the cavity was initially cleared of caries and prepared using a low-speed tungsten carbide bur. Tooth number 11 was diagnosed as Partial Pulp Canal Obliteration with no periapical involvement of bone radiographically. Since the missing tooth number 21 required replacement with a bridge, tooth number 11 was advised to undergo elective treatment endodontically for post placement. The canal is visible from mid-root to the apical region
