What kind of strokes should be used during coronal polishing?

The use of overlapping circular strokes during coronal polishing is the best approach because it effectively cleans the tooth surfaces without causing damage to the enamel or gum tissue. This technique allows for a thorough and gentle process as the circular motion can cover more area on the tooth surface, ensuring that not only the flat surfaces but also the contours of the teeth receive the necessary attention.

Overlapping strokes ensure that there is no skipped area, which is critical for achieving optimal polishing and preventing plaque and stain buildup. This method aids in minimizing the risk of scratching or harming the enamel, which can occur with more linear or jagged movements. Circular strokes are ergonomically easier for the clinician to execute and can be more comfortable for the patient, making the overall experience more positive.

In contrast, other techniques, such as vertical, jagged, or horizontal strokes, do not provide the same level of thoroughness or safety. Vertical strokes might miss areas between teeth, jagged strokes could lead to trauma on the enamel surface, and horizontal strokes are less efficient for cleaning the contour of teeth, particularly molars and premolars. Thus, the advantage of overlapping circular strokes lies in their effectiveness in achieving a smooth polish while maintaining safety and comfort.
