Mouth lamp from main. inside the tubes for about two-thirds of the length of theinstrument, a fine platinum loop is inserted, this looprequires to be heated with care as the effect of the currentupon it is not visible, as it is upon the bare loop of thecautery. The heat generated in the loop travels to thepoint and the temperature is regulated by the resistancealready mentioned. These points require from 2 to 4 voltsand 1 to 2 amperes. The root-drier has a very fine flexible point which readilydries any moisture in a root canal in which it is inserted. DENTAL ELECTRICAL APPARATUSES 151 Gutta-percha stoppings are readily trimmed and packedwith points for that purpose, after the temperature hasfirst been adjusted to the proper degree. The electric mouth lamp with mirror used for manypurposes is valuable for careful examination of the powerful light reveals dead teeth and fissures whichmay be overlooked when the mouth is examined withoutthe lamp.
