What should be the sequence of movement during rubber cup polishing?

The correct approach during rubber cup polishing is indeed to start from the gingival third and move towards the occlusal third. This technique is key for several reasons.

First, beginning at the gingival margin helps to effectively remove plaque and stains that accumulate along the gum line, which is often a critical area for maintaining periodontal health. By polishing from gingival to occlusal, the process effectively sweeps any debris and biofilm upwards, preventing any potential re-deposition of material back onto the tooth surfaces.

Additionally, this direction allows for a more controlled application of the polishing agent, ensuring that the abrasive material is applied to the tooth enamel in the optimal fashion to enhance shine and smoothness without causing damage. This approach is not only systematic but also promotes better tactile awareness and minimizes the risk of irritating the gum tissues compared to other methods.

Overall, this sequence aligns with best practices in dental hygiene, ensuring effective cleaning and maintaining patient comfort during the procedure.
