Abstract
This invention relates to a tip for a vibrating scaler for use in dentistry, the tip comprising a proximal inlet for receiving coolant; a distal working portion for being vibrated to aid scaling; and an outlet for delivering coolant received via the inlet to cool the working portion, wherein the working portion defines a concave side and a convex side of the tip and the outlet is located on the convex side of the tip. The invention also relates to a vibrating scaler for use in dentistry that comprises the tip.
Claims23
A tip for a vibrating scaler for use in dentistry, the tip comprising:
- a proximal inlet for receiving coolant;
