AquaCare It is not connected to the dental unit, it acts as a stand-alone piece, only receives high pressure air from the dental unit. It has a unique powder set with its own presentation and the same applies to the liquid. There are 4 types of powder available, including:
• A prophylactic powder (sodium bicarbonate).
• Two powders suitable for preparation (aluminium oxide 29 micron and 53 micron particles).
• The Sylc Novamin, the active bio glass used for dentin desensitization.
In this device you have the equivalent of a ring flash, twin flashes, diffusers and a polarizer, and you can combine these different lights to take new kind of dental pictures. The use of this device is so easy, all you have to do is connect your smartphone to the device, turn on the light that you want, open the camera, be at 10 to 20 cm far from the teeth, Zoom, Focus and take the picture.
For those dentists who have no experience or routine in preparation work with air abrasion, it is advised to start with the smaller (29 micron) particle size and with lower pressure, even if it is more time-consuming. Rubber dam isolation is mandatory for air abrasion procedures, and we should not forget to offer protective glasses for patients.
We usually isolate a quadrant using heavy (Nictone) rubber dam. After isolation we can start preparation using 27 microns Al2O3 with regulated pressure and with water spray (Rondoflex) or AquaCare (Velopex).
The ability to regulate:
a) air pressure
b) water flow
c) media delivery
Makes the air abrasion an extremely reliable and powerful tool. In the image one popular device Aquacare (Velopex)
The whole preparation is finished. For the 3rd molar we used a carbide bur to selectively remove soft carious tissue, as air abrasion is not effective for cutting of soft caries. Usage of carbide burs decreases the formation of the smear layer that is of outmost importance for self etching adhesion.

Air-flow applied Sylc (NovaMin) does not only remove discoloration, but it also offers a rapid, efficient and long-lasting solution for dentine hypersensitivity. The smart unit of Aqua-Care allows the clinician to apply Sylc (NovaMin) with ease, which makes it an indispensable instrument of the modern dental office.
The era of microscopes and ultrasonic devices in endodontics brought the possibility of metal post removal, which may be rational in the event that retreatment is necessary, but can be very risky in terms of dental tissue loss. There are several indications and contraindications of metal post removal, but the most important rule today should be the preservation of the coronal and radicular tooth structure, which is essential for the long-term success of endodontically treated teeth.
The metal post was sand-blasted (AquaCare Dental Air Abrasion) with 53 micron aluminium oxide particles (proCut, Coarse Cutting Powder) and the three functional monomers (4-MET, MDP and MDTP) adhesive system (G-Premio Bond, GC) was applied on the metal core and supra-gingival tooth structure in order to provide adhesion to both the dentin and the metal.
