Summary:

  • Purpose: to evaluate the cutting efficiency of Reciproc and WaveOne NiTi reciprocating instruments and their proprietary movement in a new device specifically developed for cutting tests.
  • N= 48 new NiTi reciprocating instruments, 24 Reciproc R25 and 24 WaveOne Primary files.

Materials/Methods:

  • Instruments were divided into 4 groups (n = 12): Gp 1, Reciproc activated by Reciproc ALL program; Gp 2, Reciproc activated by WaveOne ALL program; Gp 3, WaveOne activated by Reciproc ALL program; and Gp4, WaveOne activated by WaveOne ALL program.

  • Cutting efficiency of all instruments was determined by means of a specially designed testing device  consisted of a main frame to which a mobile plastic support for the handpiece was connected and a SS block containing the Plexiglas plate against which the cutting efficiency of the instruments was tested. 

  • The cutting efficiency was tested 14 mm from the tip of the instruments

Most highlighted Results:

 

  1. Reciproc instruments have statistically higher cutting efficiency with respect to WaveOne instruments.
  2. Cross-sectional design seemed to be a more decisive parameter than type of reciprocating movement concerning the cutting ability of NiTi instruments.
  3. Although no statistical significance was present, Wave One ALL movement registered greater penetration depth than Reciproc ALL movement (RW group versus RR group and WW group versus WR group).

Clinical Significance:

Reciproc instruments demonstrated statistically higher cutting efficiency than WaveOne instruments
