In plain words

What the trial is, and whether it could suit you

Gingival hyperpigmentation, particularly of melanin origin, can pose significant aesthetic concerns, especially among patients with a high smile line. Several depigmentation techniques have been proposed to manage this condition, including scalpel surgery, electrosurgery, cryotherapy, lasers, and various rotary instruments. Recently, minimally invasive rotary tools such as ceramic burs and polishing brushes have gained interest due to their potential to deliver controlled ablation with reduced postoperative discomfort and healing complications. Ceramic soft tissue trimming burs are specially designed to remove superficial pigmented gingival layers with minimal trauma. However, these instruments may still generate heat and cause a degree of tissue damage. On the other hand, polishing brushes, traditionally used for surface finishing and stain removal, have recently been explored for soft
