Innovative bur technology. Its unique carbide bur lets you explore and effectively diagnose and treat suspect pit and fissure caries while preserving healthy tooth structure. Fissurotomy^® bur tip is 0.33 mm and quickly cuts a smooth, minimally invasive groove into suspicious fissures in a single pass. The bur is designed as a depth gauge into the fissure prep. In 3–5 minutes, fissure cavity prep is cut, filled, and finished. Virtually pain-free: in most cases, no anesthesia is necessary.
