DENTAL BURR, a steel drill with fine, sharp flutes, used for removing affected parts of the tooth and preparing cavities for dental fillings. The dental burr is driven into action by means of a dental engine (see), being secured in the so-called handpiece of the dental engine. Depending on the shape of the cutting part, one distinguishes spherical, conical, flame-shaped, wheel-shaped, inverse-conical, pear-shaped, barrel-shaped, cylindrical (fissure), spear-shaped, and other forms of dental burs. The sizes of the dental burr heads range from pinhead to a large pea, indicated by a corresponding number, totaling about 18. The length of the dental burr shaft, together with the cutting surface, averages 2–5 cm.
