Summary

This study assessed how thermomechanical load affects dental adhesive bond strength and interface integrity. All tested adhesives showed reduced bond strength with increased load, with nanoleakage observed in all groups.

Area of Science:

  • Dental Materials Science
  • Biomaterials Engineering
  • Adhesive Dentistry

Background:

  • Dental adhesives are crucial for restoring tooth structure.
  • Understanding their long-term durability under functional stress is essential.
  • Thermomechanical load (TML) simulates intraoral conditions, impacting adhesive interfaces.

Purpose of the Study:

  • To evaluate ultra-morphological changes in resin-dentine interfaces after varying TML.
  • To determine the microtensile bond strengths (microTBS) of four different dental adhesives.
  • To correlate interface integrity with bond strength under simulated functional stress.

Main Methods:

  • Four dental adhesives (Syntac, Clearfil SE Bond, Xeno III, iBond) were used on human third molars.
  • Specimens underwent cyclic TML (20 N, 0.5 Hz; 5-55°C) for 0 to 100,000 cycles.

  • MicroTBS and nanoleakage via transmission electron microscopy (TEM) were assessed.

    • Main Results:

    • MicroTBS significantly decreased with increasing TML for all adhesives (p<0.05).
    • Bond strengths reduced from baseline to 100,000 cycles: Syntac (41.3/30.1 MPa), Clearfil SE Bond (44.8/32.5 MPa), Xeno III (27.5/13.7 MPa), iBond (27.0/6.2 MPa).
    • Nanoleakage was observed early in all groups, more pronounced in Xeno III and iBond; iBond showed failure origins within the adhesive layer.

    Conclusions:

    • Increasing thermomechanical load significantly compromises the bond strength of all tested dental adhesives.
    • Nanoleakage is an early indicator of interface degradation, particularly evident with certain self-etch adhesives.
    • Adhesive system choice and application method influence durability under functional stress.
