All three etching modes from one bottle, on dentine you did not get perfectly dry

Over-dried the dentine while chasing a dry field? Or left it wetter than you meant to? Adhesive failure happens at the moment of application, not months later, and surface moisture is the variable hardest to control in a deep access cavity. Prime&Bond active® is a universal adhesive designed to spread and wet under both conditions, in self-etch, selective enamel-etch or full etch-and-rinse, from one bottle.

› Etch the enamel you have cut. The IFU is explicit that unprepared enamel must be etched first – 15 s on enamel, with incidental dentine contact held to 15 s or less.
› Do not desiccate. After rinsing, the IFU says not to dry the dentine out – and contact with saliva, blood or sulcus fluid during application may cause failure.
› Watch the eugenol. Do not use eugenol- or hydrogen-peroxide-containing materials with it – the same caution that applies to the composite going in on top.
› Not for direct pulp application, or for patients with a history of allergic reaction to (meth)acrylate resins. It is acidic and can burn.

Prime&Bond active does not seem to be sensitive to the degree of moisture, and presented well-formed hybrid layers when applied to either moist or over-dried dentin.
— Prof. André Reis, Guarulhos University, on FE-SEM and TEM imaging of the hybrid layer, reported in Dentsply Sirona's own Scientific Compendium, which does not publish the figures behind it.

What the independent work shows

Almeida and colleagues used Prime&Bond active as the reference adhesive in a double-blind randomised trial of 176 restorations in non-carious cervical lesions – the hardest test there is, since nothing holds the restoration in but the bond. At 18 months, retention was 95.5% in etch-and-rinse mode and 90.9% in self-etch, and self-etch groups showed more marginal discrepancy on FDI criteria (Clin Oral Investig 2023;27:151–63). Which is the practical argument for etching the enamel.

Which etching mode should I use?
Selective enamel-etch is the sensible default and the one Dentsply recommend for Class II. The published trial above and the university work in Dentsply's compendium point the same way: etching lifts enamel bonding, while dentine is largely unaffected by mode.

Can I bond a post or a dual-cure core with it?
Only with the Self Cure Activator. The IFU lists dual-cure and self-cure work and post cementation under that combination alone – the bottle on its own is for light-cured work.
