Aim. Techniques based on NiTi engine driven files for shaping and warm gutta percha for obturing the root canal space are becoming more and more popular. Aim of this paper is to evaluate, by a clinical longitudinal study, the type of sealing and the outcome of endodontic treatment, performed by new Profile and Thermafil technique, in teeth with or without periapical lesions.
Methods. A total of 122 teeth in 64 patients were consecutively enrolled in the study; 63 teeth had normal periapical status (Group A) and 59 teeth had periapical lesion (Group B). Endodontic therapy was carried out by Profile .04 and Profile .06 NiTi engine driven files and the obturation was made by Thermafil, a filling technique based on heated gutta-percha surrounding a plastic carrier. The type of sealing was evaluated by a score (A best - D worst) and the type of healing was classified as complete, incomplete and failure according to previous published data. The radiographical outcome of the teeth was evaluated by independent observers after 24 months. Data were analysed by non parametric statistics.
Results. At the end of the study, 115 teeth (59 group A and 56 group B) were examined. The quality of sealing was evaluated and some differences were reported comparing different types of teeth. The radiographic outcome was evaluated and 94.9% showed to be completely healed in group A and 48.2% in group B (p=0.0001).
Conclusion. The technique based on NiTi engine driven files and Thermafil heated gutta-percha has shown, after 24 months, results which were comparable to other root canal shaping and filling methods.
