Objectives: The aim of this study was to assess the influence of operator experiencelevel on the lifespan of the WaveOne Primary file (Dentsply Maillefer, Ballaigues,Switzerland) in extracted teeth. Materials and Methods: Moderately curved canals ofextracted maxillary and mandibular molars were randomly distributed into 2 groups:experienced and inexperienced operators. Ten files were allocated to each group (n =10). Each canal was prepared until the working length was reached, and the same filewas used to prepare additional canals until it separated. The number of canals preparedbefore file separation was recorded. The fragment length of each file was measured,and the location of the fragment in the canal was determined. Data were statisticallyanalysed using the independent 2-sample t-test. Results: The 2 operators prepared atotal of 324 moderately curved canals of maxillary and mandibular molars. There wasno significant intergroup difference in the mean number of canals prepared (p = 0.27).
The average lifespan of the WaveOne Primary file was 17.1 and 15.3 canals, and thelongest lifespan was 25 and 20 canals, when used by experienced and inexperiencedoperators, respectively. There were no statistically significant intergroup differencesin separated fragment length and location. Conclusions: Within the limitations ofthis study, operator experience level appears to have no effect on the lifespan of theWaveOne Primary file in preparation of moderately curved canals. Single teeth withmultiple canals can be prepared safely even by a novice operator by using a single file.
