Answer to Vol 234 Issue 8: In 1892, Martin L Bosworth, from Rhode Island USA, patented an improvement to his original dental plugger of the year before. This new design incorporated a sprung tip which, under pressure, retracted part-way into the head before springing back once pressure was released. The pressure required could be adjusted by turning the screw beneath the casing. The process of filling teeth, especially with gold foil, could take hours; so, the mechanical advantage of this ‘plugging machine’ would have reduced the fatigue associated with the procedure by speeding up the process quite considerably. To the relief of both dentist and patient!
