After the assembly of the CVDentus tip in the hand piece of the ultrasound equipment, it is ready for the use. However, a last very important detail is still necessary: to adjust the water flow to the tip.

The flow does not need to be excessive. It is enough to make water to drip in the extremity of the active tip.

It is interesting to note that, by effect of the ultrasound, the water drains adhered to the connecting rod and, even in positions of difficult access, the water reaches the active tip.

Even for tips of multiple folds the water drains adhered on the connecting rod, making an efficient refrigeration of the treated area.

Depending on the ultrasound power, it can cause a certain spreading of water around the CVDentus tip. In some equipment this spreading is sharper and, in these cases, it is necessary to regulate the ultrasound power and the water flow to guarantee the refrigeration of the treated area.

Different ultrasound equipment presents different possibilities of refrigeration. The majority of them are simply connected to the water reservoir that feeds equips of the doctor's office.

There are some that has the possibility of independent refrigeration, either through a peristaltic pump or an independent reservoir pressurized with compressed air.

In these cases, other liquids or solutions of refrigeration can be used, in accordance with the recommendations of the manufacturer of the ultrasound equipment.

There are no restrictions of use of the CVDentus tips with other liquids of refrigeration recommended for the procedure in course.
