Wave one® system: clinical experience on 46 cases

Objective: The objective of this study was to evaluate root canal preparation with the Wave One® system as well as single cone endodontic obturation techniques and with staked obturators from the same systePm. Materials and Methods: 31 patients with 46 teeth and 76 roots canals were included. The roots canals were prepared with Wave One® files and fillled with calibrated cones or stake plugs from the same system. The average times of root canal preparation and filling were measured. The quality of the filling was evaluated by post-operative radiographs according to its limit and density. In addition, errors during shaping and root canal filling were investigated. Results: The average duration of canal shaping was 9.85. For root canal obturation, the average duration was 6.69 with the single cone technique and 5.55 with the stake system (p > 0.05). Concerning the apical limit, the single cone technique had 90.6% of adequate limit and the stake system 83.3% (p > 0.05). The single-cone technique showed 7.8% of parietal voids and the stake system 16.6% of parietal and central voids (p > 0.05). Finally, no accidents were reported. Conclusion: This study shows that root canal preparation with Wave One® followed by filling with cones or stake plugs of the same system provides satisfactory results.
