Which instrument stroke is used to remove cement?

The use of short oblique strokes is optimal for removing cement during dental procedures. This technique allows for precise control and directs the instrument effectively against the surface from which the cement needs to be removed. Short oblique strokes utilize a motion that can effectively fracture the bond of the cement while minimizing the risk of damaging the underlying tooth structure or adjacent tissues.

Using this approach helps in achieving thorough removal without exerting excessive pressure, which is essential for preserving the integrity of dental surfaces. It offers a balance between effectiveness in removal and safety, making it the preferred method in dental assisting practices when dealing with cement removal.

In contrast, the other techniques may not be as effective for this specific task. Long sweeping strokes may inadvertently spread material rather than remove it, while circular strokes might not provide the necessary focus and control for targeted cement removal. Back-and-forth strokes can also risk damaging the tooth surface if not used carefully. Thus, short oblique strokes are specifically advantageous in this context.
