Aim The aim of this Case Series was to evaluate the radiographic quality of root fillings performed 5 years previously using the noninstrumentation technology (NIT)‐obturation method and to assess radiographically the outcome of these root canal treatments. Methodology Seventeen patients requiring root canal treatment participated in this study and were re‐evaluated after 5 years. After instrumentation with K‐Flexofiles, Calcium‐Hydroxide inter‐appointment dressing, re‐entry and copious irrigation with NaOCl, the teeth were root filled using the NIT. Results Immediately after obturation the root fillings were (−0.78 ± 0.11 mm) short when taking the radiographic apex as a reference point. After 60 months these values were −0.85 ± 0.11 mm. No statistical difference was found ( P > 0.05). In the periapical region, PAI rating 1 and 2 increased from 20.1% to 75.6% after 60 months. Conclusions • This prospective Case Series demonstrated the performance of the NIT‐obturation method in vivo . • Root canals filled by the reduced‐pressure method using sealer combined with gutta‐percha cones showed good radiographic quality. • Periapical healing after 5 years was comparable with conventional filling techniques.
