| 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.

| #1) 19024260 | Abdalla/2008 | 125 Class V non-carious cervical lesions (NCCL) with incisal or occlusal margins in enamel and gingival margins in dentin/cementum | Randomized Controlled Trial | | Key results | No 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. | |
