Title |
Use of total etch systems in resin composite treatments superior to self-etching Systems for bond strength |
Clinical Question |
When bonding resin composite to enamel, do self-etching systems or total-etch systems provide a stronger bond? |
Clinical Bottom Line |
The SEB (total etch systems) yielded the highest micro tensile strength to all regions of dentin. (See Comments on the CAT below) |

Comments on
The Evidence |
The authors investigated the micro tensile strength of the self-etch and total etch bonding systems bonded to different regions of dentin. This study showed that regardless of the tested dentin surfaces, SEB (total etch systems) attained the highest micro tensile bond strength to smear layer-covered surfaces. |
Applicability |
These results would seem relevant to all long flat cavity preparations |

Comments and Evidence-Based Updates on the CAT
(FOR PRACTICING DENTISTS', FACULTY, RESIDENTS and/or STUDENTS COMMENTS ON PUBLISHED CATs) |
by Stormy Laing (San Antonio, TX) on 04/18/2012 A PubMed search on this topic was conducted in April 2012 and more recent and stronger evidence was found: PubMed ID 20672727. This RCT finds that there is no significant difference in the micro-tensile 24 hour bond strength when using a 2 step self etch system in comparison to a 3 step etch and rinse system, neither in dentin or enamel. Indicating that because similar bond strengths can be duplicated by both systems, the choice of which to use is left to the discretion of the clinician and the situation. | |
