    Dental burs have revolutionized the dentistry field and are used for cutting hard tissues such as bone or tooth [1,4,6–9]. They are normally made of stainless steel, diamond grit or particles, and tungsten carbide and fitted to a dental drill incorporating an air turbine. The dental bur was developed <300 years ago [8] and still widely used.
