prime&bond one SELECT

prime&bond® one SELECT
Literature often recommends the use of a self-etch adhesive in cavities with a large proportion of exposed dentin in order to minimise the risk of post-operative sensitivity.  However, etch&rinse adhesives often show superior long-term results on enamel. prime&bond® one SELECT combines advantages from both techniques.  It provides high bond strength in all etching techniques (self-etch, etch&rinse and selective enamel-etching) and delivers reliable performance even on over-dried dentin, resulting in virtually no post-operative sensitivities.
 
 





What is prime&bond one SELECT?
prime&bond one SELECT is a one-component dental adhesive designed to bond resin-based, light-curing restorative materials to enamel and dentin.
It can be used in all etching techniques:
•             Self-Etch
•             Etch&Rinse
•             Selective Enamel Etching
 

 What makes prime&bond one SELECT so different?
prime&bond one SELECT provides high application security even on over-dried dentin. This results in a consistent, reliable performance and virtually no post-operative sensitivities[1].The acetone-free composition allows chairside storage at room temperature and 30 minutes working time in a closed CliXdish.

High application security and well balanced bond strength
The application of prime&bond one SELECT results in reliable bonding, regardless of whether the dentin is too wet or too dry. One of the great aspects about prime&bond one SELECT is that it successfully establishes a hybrid layer which results in tight marginal seal and virtually no post-operative sensitivity.

What technique does prime&bond one SELECT cover?

In Class V lesions that are located close to the gingiva, the application of an etching gel often triggers bleeding, which can subsequently lead to contamination of the lesion‘s surface. On a contaminated surface, the development of bond strength is impaired. As a consequence, a self-etch technique is preferred.

Class IV restorations are identified by a small retention area and high shear stress. Therefore the highest possible adhesion is needed. Here, an etch&rinse approach is normally preferred.

In a deep Class II cavity you may want to protect the pulp by not exposing the dentin to phosphoric acid. In order to ensure tight marginal seal of the restoration, separate etching of the enamel is preferred. prime&bond one SELECT covers all these various approaches

Features and Benefits

FEATURE BENEFIT  SO WHAT? WHAT DOES THIS MEAN FOR YOU ?
Can be used in all etching teqhniques.  Flexibility to choose the preferred etching technique depending on clinical situation. Convenience  prime&bond one SELECT has been shown to deliver high bonding performance in all etching techniques (etch & rinse, self-etch and selective enamel-etch). This means that you can be rest assured that one single bonding agent can give you the highest degree of clinical flexibility, removing the need for you to carry different bonding agents for different clinical situations.
High application security on both wet and dry dentin  Virtually no post-operative sensitivity Technique tolerance and patient satisfaction  Typically optimum bond strength can only be achieved when the cavity/dentin moisture is not too wet or not too dry. If the cavity/dentin is over-dried post-operative sensitivity will occur, resulting in patient discomfort usually requiring follow up action. Optimum dentin moisture can be difficult to achieve; prime&bond one SELECT provides high application security on both over wet and over dry dentin. This removes the guesswork and pressure to achieve optimum dentin moisture and gives you confidence that the bond will not only provide a robust performance but also significantly reduce the risk of post-operative sensitivity. As a result, impoving  patient satisfaction and reducing the possibility of your patient returning for follow up treatment.
Reliable product with high bonding performance  Superior bond strength  Safety & performance  Bond strength is one of the most important characteristics of adhesives. prime&bond one SELECT delivers high and well balanced bond strength in both self-etch and etch&rinse technique giving you confidence that the restoration will have a maximum longevity. It has an important influence on the longevity of the overall restoration.

30 minutes storage in closed ClixdishTM  Long working time  Cost saving and convenience  Many adhesives require dispensing of a separate dose for every tooth treated, simply because they evaporate too quickly. prime&bond one SELECT has a working time of up to 30 minutes from a closed CliXdish and may therefore be used on several cavities on the same patient. This helps you save costs by reducing wastage.
No refrigeration Chairside storage Convenience

1. Question: What are the reasons for post-operative sensitivity?
  Answer: There are many reasons for post-operative sensitivity that are not related to the adhesive, e.g. the depth of the cavity or the rotational speed and heat development of the bur during excavation etc.

However, the 2 main reasons for post-operative sensitivities relating to the adhesive procedure are over-etching and over-drying.

1. Over-etching: this happens when the dentin is etched too long. The dentin becomes too demineralised and too much of the collagen network is exposed so the adhesive is not able to fully infiltrate and penetrate through the exposed fibres.
2. Over-drying: after rinsing the phosphoric acid, the residual water has to be evaporated. If the cavity is dried too much, the exposed collagen fibres will collapse. Most adhesives cannot infiltrate and penetrate through the collapsed collagen network to create a distinct hybrid layer. The adhesive just “lies on top” of the collapsed collagen network. The collapsed collagen fibres might also block the tubules and inhibit proper infiltration.

In both scenarios open spaces (within not fully hybridised collagen) are connected via tubules to the nerve receptors that are sensitive to any fluid movement (e.g. while chewing on the restoration).

The ideal surface of the dentin during restoration is neither too dry nor too wet allowing the resin to penetrate with a high degree of infiltration allowing the formation of a distinct hybrid layer and sealing of the tubules.

2. Question: How do Self-Etch adhesives “work”?
  Answer: Self-Etch adhesives contain acidic components which allows for etching that is comparable to phosphoric acid. Etching, demineralisation and infiltration of the resin into the tubules and the collagen fibres happens at the same time. While etching, the acidic monomers dissolve calcium and phosphates from the tooth structure and get neutralised. Furthermore, these monomers get polymerised into a network and are immobilised upon curing.
3. Question: Why are Self-Etch adhesives believed to cause less post-operative sensitivities?
  Answer: In the etch&rinse procedures phosphoric acid demineralises the dentin and exposes collagen fibres and tubules, the phosphoric acid is not neutralised by calcium and phosphates. The longer the acid stays on the tooth, the deeper it will etch. If the acid remains on the dentin for more than 15 seconds there is a risk that the dentin will be over etched.
To remove the acid, the dentist has to rinse it away. After rinsing, the residual water needs to be evaporated. If the air is applied too long or the stream is too strong, the collagen network may collapse, resulting in post-operative sensitivity.

4. Question: Why is prime&bond one SELECT not compatible with the Self - Cure Activator?
  Answer: prime&bond one SELECT has a rather low pH value (1.6). This low pH value enables prime&bond one SELECT to establish high bond strength on enamel even in self-etch mode. In contrast, the Self-Cure Activator (SCA) was developed for adhesives with a higher pH and is not able to compensate the high acidity of prime&bond one SELECT resulting in insufficient adhesion at the cement-interface.

5. Question: What are the reasons for white discolorations?
  Answer: With the formulation of prime&bond one SELECT, the occurrence of white discolorations is reduced to a minimum. The incidence is now less than 1%.
When speaking of “white discolorations” dentists often mean different things:
a) White discolorations on the gingiva: these white discolorations occur when the gingiva gets in contact with the adhesive and are caused by the acidic components. These white discolorations usually disappear within a few days.
b) White discoloration of adjacent teeth or surrounding tooth surfaces: these white discolorations occur when the adhesive is accidentally splattered onto untreated tooth surfaces (e.g. during air drying). It absorbs water or saliva remnants and is perceived as a white stain. It can easily be removed by polishing.
c) White discolorations on the margins of the restoration: These white discolorations occur when the adhesive is not air-dried sufficiently. It is very important to evaporate the solvent thoroughly at least for 5 seconds or even longer, until there is no more movement of the adhesive layer.
If the cavity is very wet from residual water, the evaporation might take longer.
