• Distinct blue color for a strong contrast to the tooth which minimizes the risk of over-etching.
• Consistent material thickness for a quick and effective application
• Angled metal tip for exact application

N-Etch is an etching gel containing 37% phosphoric acid. N-Etch is used for enamel etching and dentin conditioning in conjunction with composite restorations, sealants and the adhesive luting of indirect all-ceramic or composite restorations.

N-Etch is the best partner for Tetric N-Bond Universal for enamel etching and dentin conditioning.

Indications

• N-Etch is a gel used for enamel etching and dentin conditioning in conjunction with adhesives, composites, luting materials and fissure sealants.

Composition

N-Etch contains phosphoric acid (37 wt.% in water), thickeners and pigments

N-Etch recommendation: Refrigerate large stocks at 2-8 °C (36-46 °F)

• 1 x 30g N-Etch Jumbo
• 1 x 2g N-Etch
• Various Accessories

• Step 1:

Apply N-Etch on enamel and subsequently on dentin; and allow a reaction time of 15 seconds.

• Step 2:

Afterwards, thoroughly rinse off the etchant with water spray and dry the tooth surfaces with oil-free air.

• Step 3:

Avoid excessive drying of the dentin.

• Step 4:

The etched enamel surface should have a chalky white appearance.

•  Step 5:

If this is not the case, repeat the etching procedure using a shorter reaction time.

• Step 6:

If the tooth surface becomes accidentally contaminated (e. g. with saliva), repeat the etching procedure with a reaction time of max. 10 seconds.

• Step 7:

The reaction time on unprepared enamel (e.g. fissure sealants) is 30-60 seconds.

• Step 8:

If the enamel is selectively etched, use a reaction time of 15-30 seconds.
