Sequence of actions

Criteria of correct performance

1.

Apply the conditioner (10-25% water solution of polyacrilyc acid) to the cavity walls for 10-30 sec., if included in the set to remove debris and activate ions of Ca and P of hard dental tissues.

Conditioner covers the cavity walls and floor.

2.

Rinse with water for 10-60 sec.

No conditioner left in the cavity.

3.

Dry the cavity for 10-20 sec. with cotton ball.

Cavity is slightly wet.

4

Put the glass plate (smooth surface up) or a paper pad for mixing of the material on the table.

Glass plate is dry.

5.

Apply necessary amount of liquid on the pad. Hold the bottle high for the liquid to drop freely.

Consult the manual about the powder-liquid ratio, follow the instructions.

6.

Shake the bottle with powder before opening. Use the measuring spoon (included) to measure the necessary amount of powder. Put the powder on the pad.

For restorative GIC powder : liquid ratio is 3:1 (1 spoon + 1 drop)

7.

Divide the measured powder into 2 equal parts.

8.

First half of powder quickly mix with the liquid for 10-20 sec. using plastic spatula.

Mass is homogenous.

9.

Add the second half of the powder to the homogenous mass and mix for 20 sec. General mixing time is 30-40 sec.

Mass is homogenous and glossy.

10.

Introduce the whole portion of material into the cavity using plastic instruments. Condense it. Modeling of the filling should not exceed 1 min.

Filling material fills the whole cavity and is adjunct to the cavity walls.

11.

Primary correction of the filling is done after the setting time (4-5 min.) with carborundum stones and flexible abrasive discs.

Surface of the filling is smooth, restores the anatomical shape of the tooth (occlusal or vestibular surface in the cervical region).

12.

If the isolating varnish is included in the set, apply it to the filling and blow with air

Filling is glossy.

13.

Finishing and polishing is done with diamond heads, flexible disks, rubber cups with polishing paste on the next visit (after 24 hours) after the final setting of the filling.

Filling is smooth.

14.

Coat the filling with a varnish for a second time, blow with air.

Filling is glossy.
