Which motion is recommended when performing a mechanical polish?

The recommended motion when performing a mechanical polish is short, overlapping, intermittent, wiping, and lifting. This technique allows for an effective and controlled polishing process, helping to achieve a smooth and shiny surface on the teeth while minimizing trauma to the gingival tissues and enamel. By using short, overlapping strokes, the dental assistant ensures that every part of the tooth's surface is polished adequately, preventing the accumulation of debris and polishing paste in one area, which could lead to damage or uneven surfaces.

This approach also emphasizes the importance of being gentle and precise, which is crucial to avoid excessive abrasion on the tooth surface. The lifting motion is particularly important as it helps to reduce heat build-up from the polishing instrument, further protecting the enamel and pulp from potential harm during the procedure.
