| Abstract ： | This study investigated radiographic evaluation of 186 root canal treatments in 90 cases (49 apical periodontitis, 29 irreversible pulpitis and 17 reversible pulpitis) by ProTaper and Obtura II system. Radiographs taken immediately post-obturation were evaluated to outcome of ProTaper preparation and Obtura II obturation. The level of the final root filling was classified as short (more than 2 mm short of the apex), flush (within 2 mm) or over (beyond) in 12.4%, 83.9% and 3.8% cases, respectively. All broken files were removed by ultrasonic instrument, although SX files were broken twice in this study. These results showed that ProTaper and Obtura II systems decreased the excess filling case compare with the standard preparation by stainless steel files. |
