Abstract
  • A new method for determining root canal working length (WL), the paper point technique (PPT), has been claimed to be accurate and reproducible, but has not been formally evaluated. Hypothesis: WL determination is more accurate when the Electronic Apex Locator Technique (EALT) is supplemented with PPT compared to EALT alone. The lengths of 84 root canals of unsalvageable human teeth were measured first using EALT, then PPT. Endodontic files were cemented to the position indicated by PPT. The teeth were extracted and microCT-scanned. In 71 canals that provided adequate readings for both EALT and PPT, the RCAE to file tip distance was measured to 20 μm resolution. Both techniques showed (1) moderate agreement and (2) excellent repeatabilities. There was (3) a significantly greater accuracy in locating the RCAE when PPT was used compared to EALT alone (p ≤ 0.0051). Conclusion: It may be advisable to supplement the EALT measurement with PPT.
