Title Etching with 30-40% Phosphoric Acid Not Needed With Clearfil SE Bond Self-Etching Adhesive System
Clinical Question In a Class V non-carious lesion, will etching with 30%-40% phosphoric acid prior to application of Clearfil SE Bond self-etch primer, as compared to a non-acid etching technique, affect clinical performance of the adhesive?
Clinical Bottom Line Based on the evidence of no loss in restorations, there is no significant difference between the two techniques. Clinical performance is adequate with just the Clearfil SE Bond self-etch adhesive system. This finding cannot be applied globally to all self-etching adhesive systems.

(level of evidence)
#1) 19024260Abdalla/2008125 Class V non-carious cervical lesions (NCCL) with incisal or occlusal margins in enamel and gingival margins in dentin/cementumRandomized Controlled Trial
Key resultsNo loss of restorations was recorded after 1 and 2 years for the two restorative techniques. There was no significant difference between the baseline, 1-, and 2-year results for any of the tested techniques. However, restorations made after acid etching showed less marginal discoloration at the enamel margins.

Comments on
The Evidence
This experimental study incorporated both randomization and control. A good amount of accurate evidence was carefully analyzed.
Applicability These results apply to the dental practitioner’s technique when deciding to use a self-etching system for restoring non-carious lesions.

I am really Impressed with CAT library. It is a great resource for general dentist. I found my self going over some of the hot topics that could have an effect on my everyday practice. For example, this CAT summery talks about Clearfil SE Bond self-etch adhesive system. I am a firm believer in 4th and 5th generation bonding systems. Looking at this summary, I wouldn’t mind looking into Clearfil SE bonding system for sensitive teeth and tooth brush abrasions.
