Summary

3D profilometry and Scanning Electron Microscopy (SEM) offer complementary insights into bovine bone surfaces prepared with sonic files. SEM excels at debris visualization, while 3D analysis better reveals surface topography and cut depth.

Area of Science:

  • Biomaterials Science
  • Dental Materials Science
  • Surface Engineering

Background:

  • Sonic files are used in dentistry for root canal preparation.
  • Understanding the surface characteristics created by sonic instrumentation is crucial for clinical success.
  • Bovine bone serves as a suitable model for human bone studies.

Purpose of the Study:

  • To compare 3D profilometry and Scanning Electron Microscopy (SEM) for analyzing bovine bone surfaces.
  • To evaluate the surface modifications produced by different sonic files (Heliosonic, Rispisonic, Shaper) under varying operational conditions.
  • To assess the impact of operator-assisted movement on the cutting efficiency and surface characteristics.

Main Methods:

  • Polished bovine bone specimens were instrumented using Heliosonic, Rispisonic, and Shaper sonic files at full power and 100g interfacial load.
  • Two experimental conditions were tested: no operator-assisted movement and operator-assisted movement.
  • Surface analysis was performed using a 3D Form Talysurf profilometer, followed by gold sputtering and examination under a Scanning Electron Microscope (SEM).

Main Results:

  • 3D profilometry and SEM provided complementary data, with each technique offering unique information.
  • 3D analysis effectively characterized surface topography and provided superior depth measurements compared to SEM.
  • SEM was more effective in visualizing debris on the prepared surfaces.
  • Distinctive cutting patterns were observed for each file type.
  • Cutting without operator assistance resulted in abrasion due to longitudinal file action.
  • With superimposed operator movement, continuous chip formation was evident, particularly with Rispisonic and Shaper files.

Conclusions:

  • Both 3D profilometry and SEM are valuable tools for evaluating sonic file instrumentation on bone surfaces.
  • The choice of sonic file and the presence of operator-assisted movement significantly influence the resulting surface topography and debris formation.
  • 3D profilometry offers advantages in assessing topographical detail and depth, complementing SEM's debris visualization capabilities.
