Directions To Use

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.
