Challenges in Removing Pins/Posts Without a Perforation

From 1902-1910, the <i>Dental Era</i> was published in St. Louis, MO on a monthly basis. It was the publication of the John T. Noble Dental Manufacturing Company. The Editors were John Kennerly and Hermann Prinz. This publication became part of the St. Louis Media Corporation that was established in 2010. Its focus was multifold in that it offered dentists clinical techniques, tricks of the trade, original short communications, business advice, details on newly approved patents for dentistry, society updates, and in particular translations of publications from primarily European sources. One of the more challenging aspects of dentistry at the end of the 19^th century was the potential revision of previous restorative/endodontic procedures, such as removal of pins/posts/ dowels from the root without perforation.
