Resumen

TESSORE, Romina et al. Human dentin bond strength of a chlorhexidine containing universal adhesive system used in total-etch and self-etch mode. Odontoestomatología [online]. 2020, vol.22, n.35, pp.20-29.  Epub 01-Jun-2020. ISSN 0797-0374.  http://dx.doi.org/10.22592/ode2020n35a4.

Objectives:

To evaluate the microtensile bond strength to human dentin of a chlorhexidine containing universal adhesive system applied in the total-etch and self-etch modes.

Methods:

20 third molars were randomly divided into 4 groups according to the universal adhesive system (Single Bond Universal ®, 3M ESPE and Peak Universal Bond®, Ultradent) and application mode used (total-etch and self-etch). Specimens were performed and subjected to a microtensile bond strength using a MTS SANS universal testing machine.

Results:

No statistically significant differences were found in the microtensile bond strength between the four groups studied.

Conclusions:

The bond strength of a composite resin to human dentin was not affected by the use of a universal adhesive system containing chlorhexidine in its composition applied in the total-etch and self-etch mode.
