We should try to make our greatest effort to protect healthy teeth structures in our daily practice. In this article we show a protocol of minimal preparation with sandblasting,

The complain of patient – color alteration in the certain part of tooth. Clinical finding, occlusal cavitation permeable to the dental probe.

Fig 2.- The first stage will be anaesthesia and field isolation.
Fig 3.- Isolation with liquid dam along the edge of the lesion area to preserve from abrasion the healthy tissues around the operative area..
Fig 4.- Preparation of injured tissues with Rondoflex 27 micron Al2O3.
Fig 5.- After preparation we etch the enamel with 37% orthophosphoric acid for 30 seconds. Then a self etching agent was applied (Scotchbond Universal) and doing it for a minimum of 20 seconds. After this we apply light air pressure for 5-10 seconds. After thinning the bonding layer we polymerize for 60 seconds. Then we put a minimum amount of Bulk fill composite 3M Filtek and then we finish modelling with one A3B mass Filtek Ultimate as a final layer (veneering material) as described in the Bulk and Body technique.

Conclusions

Conclusions

We need to protect healthy tissues with liquid dam when preparing with air flow abrasive systems. This is a convenient way to do a minimal preparation without harming surrounding tissues.
