File hirschfeld fig. 5/11 with handle no. 4

One of the most notable people included in the "Hirschfeld Files" is Leonardo da Vinci. Though there is no definitive proof that da Vinci was homosexual, many historians believe that he was based on the evidence of his close relationships with other men and his lack of interest in women.

The smaller Hirschfeld files are used to remove thick burnished calculus or to break up heavy calculus in places with tighter tissue. The periodontal file's head is made up of a base and several blades or cutting edges. The four working ends of periodontal files are paired devices that are used on each of the four surfaces of a tooth. The distal and mesial aspect are covered by the Hirschfeld File number 5/11.
