FISSURE CARIES TREATMENT
Settings:
Media
- 29 micron Aluminium Oxide (blue).
Nozzle

Power
- 4 bar.
Media Flow
- Slightly under midway position.
The AquaCare is of particular use for treating fissure caries.
Hold the cutting nozzle about 2mm from the surface of the tooth and direct the
particulate beam at the caries. Use it in short bursts, sweeping it along the vein until all
the dark caries are removed and the sound tooth structure is revealed.
The beauty of the procedure is its speed and the absolute control possible, ensuring that
the minimum amount of tooth structure is removed.
The newly prepared surface, being dry and abraded, is now ready for restorative
materials. Normally local anaesthetic is not necessary for the above treatment.
NOTE:
If there is soft caries present in the dentine, a rotary instrument may have to
be used, or use the Sodium Bicarbonate on “cleaning” setting. This is because soft and
moist caries are resilient and therefore not so effectively removed by the use of fluid
abrasion.
NOTE:
Stop the process periodically to check progress visually.
AquaCare: Operation
Approx. 2 mm
away from the surface.
