by Owens, Slaven, Phebus, Ragain
To quantify the depth of cure (DOC) of a composite resin system using two
different testing criteria.

Questions:
 1) Which of the following statements is CORRECT
regarding both DOC testing methods:
  1. SonicFillâ„¢ composite resin revealed significantly greater DOC compared to Herculite Ultraâ„¢ composite resin
  2. Herculite Ultraâ„¢ composite resin showed significantly greater DOC compared to SonicFill composite resin
  3. There were no significant differences in DOC between the two composite resin systems
  4. There were no significant differences in DOC, comparing shades (A1 versus A3), of the two composite resin systems
 2) The DOC can be affected by several factors
associated with the source of light energy including factors such as:
  1. Spectral wavelength distribution
  2. Intensity
  3. Exposure period
  4. Distance from the material
  5. All of the choices are correct
 3) The restorative system, SonicFillâ„¢, uses sonic energy for insertion of composite resin into posterior teeth preparations employing one bulk increment. Preliminary in vitro research has reported ___ mm DOC in 80% of the cases.
  1. 2.0
  2. 3.0
  3. 4.0
  4. 5.0
  5. 6.0
 4) Regarding testing of dental materials, ISO is an
abbreviation for:
  1. International Society of Testing Organization
  2. International Organization for Standardization
  3. International Statistical Standards Organization
  4. International Standards Officialdom
  5. None of the choices are correct
 5) According to the present study, which of the
following methods for DOC testing seemed to be the most realistic approach:
  1. Steel cylinder
  2. Teflonâ„¢ tube
  3. Extracted teeth
  4. Glass mold
  5. Rubber tube
