Total Etch Adhesive | Stae

Supplier: SDI Limited

Single component total etch adhesive.


Stae is a fluoride releasing single component dentin/ enamel total etch adhesive system, designed for direct bonding.
Stae completely and homogeneously infiltrates the hybrid layer to ensure uperior bonding to the tooth.

One bottle system
Stae combines both primer and adhesive in one bottle to simplify the technique and decrease patient chair time.

Fluoride release
Fluoride’s cariostatic effect enhances remineralisation and inhibits enamel demineralisation. In an aqueous environment, the fluoride ions in Stae diffuse from the resin into the surrounding tooth. This ionic movement is caused by oral fluid passing in and out of the resin and tooth, acting as a carrier for the fluoride ions.

Non Bis-phenol A
Stae avoids the Bis-phenol A hormonal imbalance controversy, as it does not contain the related BisGMA resin.

Dental Advisor rating
“Stae is a highly recommended adhesive system designed for composite, compomer, and porcelain bonding. It received an 86% rating.”(1)

Bonds to moist and dry tooth surfaces
Stae’s carrier solvent is a mixture of acetone and water. The acetone carries Stae deep into the demineralised dentin and the water re-moistens any dry dentin.

High bond strength
Stae’s complete hybridisation of the resin into the demineralised dentin results in high bond strength.

Complete and consistent hybridisation
“SEM observations of the Stae adhesive system revealed hybridisation at the dentin-resin interface. The hybrid layer appears well developed with a uniform thickness of around 3 to 4 microns.”(2) Stae’s well infiltrated hybrid layer, compared to the other brands below, illustrates Stae’s complete sealing of the dentinal tubules, minimising post operative sensitivity. Evident in the photographs is Stae’s “intimate adaptation of the interdiffused resin to the remaining sound tooth structure and uniform image density.

There are no gaps or voids visible within the hybrid layer. Such a characterisation has previously been associated with adhesive systems with durable clinical success.
A similar result was found with 3M Single Bond* adhesive system. With the Optibond Solo* adhesive, a less well defined hybrid layer resulted. Within the layer are areas void of resin interdiffusion. Further, the non-uniform image density suggests a lack of complete hybrid layer development.” (3)

No voids
Stae’s “hybrid layer is continuous with the residual dentin layer with no evidence of separation or voids.”(2)

Complete seal
Stae’s “hybrid layer is very uniform with no variation in staining which represents a uniform interdiffusion of adhesive resin into the demineralised layer. The collagen framework appears totally encapsulated with resin.”(2)

Intact collagen
“Collagen fibrils within the hybrid layer show evidence of complete banding with no signs of denaturing or loss of structural integrity.”(2)
