Primary molars: class II cavites preparation and high density GIC restoration

1/Cavity preparation:
The design follows Black's principles for better retention of the material. Loss of substance for a temporary tooth is less problematic than for a permanent tooth.

Rubber dam: NicTone medium, 12A/13A clamps
Ceramic burs: CeraBur (Komet)
Air-abrasion: Rondoflex 360 (Kavo), alumine powder 50 µm

2/Restoration:
A high density GIC is very different from a historical low viscosity GIC. Mechanical properties are greatly increased and this material is very suitable for primary teeth restorations.

Matrix and ring: Lumicontrast ref. 6705 (Polydentia)
Polyacrylic acid: Cavity conditionner (GC), 10 sec
High density GIC: Fuji Equia Forte (GC), 2,5 min setting time
Isolation varnish: Fuji Coat (GC)
