While total-etch adhesive systems have a track record of more than 12 years,1,2 self-etch adhesives have won favor with many dentists due to their simple technique and reduced risk of post-operative sensitivity. To understand why this is, a review of the properties of both types of systems is necessary. Due to the fact that self-etch adhesives simultaneously etch and prime, there is a reduced risk of these problems. By first applying a 35% phosphoric acid to enamel margins, clinicians can help create a stronger bond to the enamel when using a self-etch material.

Some data show that self-etch systems produce just half as much post-operative sensitivity as total-etch products, although data suggest that the sensitivity seen with total-etch adhesives, which involve multiple steps, depends on clinical technique3,4,5,6 Thus, while total-etch systems have accumulated more years of data, self-etch adhesives offer a compelling, patient-friendly advantage.
The material is designed to surround the collagen fibers in the dentin, enabling it to create a hybrid layer on wet or dry surfaces.
Applying the etchant only to the enamel areas results in a localized deep etch, allowing the dentist to maintain the benefits of the self-etch adhesive on dentin. 5: 3M™ ESPE™ Adper™ Easy Bond Self-Etch Adhesive was brushed on all surfaces for 20 seconds and gently air dried for 15 seconds. 6: The adhesive was light cured with the 3M™ ESPE™ Elipar™ Freelight 2 LED Curing Light for 10 seconds. 7: 3M™ ESPE™ Filtek™ Supreme Plus Universal Restorative was placed in 2mm increments, with each increment light cured for 20 seconds. 9: Three years following its initial placement, the restoration continued to show natural esthetics and an imperceptible margin. If the item is returned for any other reason you are responsible for the return shipping charges.

On dentin, the acid etch removes the smear layer and exposes collagen fibers, allowing the adhesive to penetrate and interlock with the fibers. A 12-Year Clinical Evaluation of a Three-Step Dentin Adhesive in Noncarious Cervical Lesions. However, when using total-etch systems, dentists must take care not to over-dry the surface, which causes the collagen fibers to collapse. Due to this, selectively etching enamel surfaces is recommended when using 7th generation materials on uncut enamel surfaces.
