Encyclopedia article (1928–1936)
DENTAL DRILL, is used in dentistry to impart rotational motion to the bur (see Dental Bur). Dental drills are available in foot-operated (see fig. 2) and electric models (see figure 1). The former are activated by the dentist's foot (or his assistant); electric dental drills are equipped with a suitable motor. The modern dental drills were preceded by various manual devices. It is believed that the prototype of the modern foot-operated dental drill was constructed in 1868 by the American dentist Morrison.
FIG. 1.
The main components of the dental drill are: the upper part, consisting of the so-called sleeve and attachment, and the lower part, consisting of the pedal, flywheel, and stand. The interior of the sleeve consists of a large spiral, about one meter long, and a small spiral (10-15 cm long). The attachment serves to secure the bur. Production of dental drills until recently was exclusively foreign (at present, the manufacture of foot-operated dental drills is being established in the USSR as well).
