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.
