Various forms of sealing cements have been used in root canal procedures since the mid-1800s to create an impervious seal of the root canal system. In the process both entrepreneurs and charlatans have risen to the challenge. During the first half of the 20^th century, significant activity in this realm was realized, which set the standards for the evolution of contemporary materials and applications.

Victorian era patent medicines to soothe discomfort from teething infants worked well because they contained dangerous pain killing drugs such as narcotics and alcohol. Relief from teething discomfort can also be achieved for a teething infant by the baby chewing on various objects such as hard teething rings or teething necklaces.

This report offers some historical perspective on infant teething and describes and pictures a well-marketed German teething necklace of the 19th century.

Professor Bruno Richard Seifert (1861-1919) (Fig.1), a renowned German chemist, invented a mouthwash that combined an antiseptic with essential oils. (https://second.wiki/wiki/richard_seifert). Karl August Lingner (1861-1916) (Fig. 2), of Dresden, Germany, produced and introduced Seifert's mouthwash in 1892. It was called "ODOL." An excellent review of Lingner's life can be accessed on this website: (https://second.wiki/wiki/karl_august_lingner). Along with ODOL Mundwasser (Mouthwash), ODOL Zahnpasta (Toothpaste) was also produced (Fig. 3). ODOL products are still sold today, 130 years later!

Many successful dentists and doctors enjoy a wide variety of hobbies, including music. Some are avid listeners; others play instruments as amateurs or even professionals; sometimes they sing. A few are recording artists. Their interests might be classical or modern, including jazz. This paper examines the musical lives of a few general practitioners, hospital dentists and academics in the United Kingdom. Clearly striving for success in one's profession leaves room for other activities.

Attempts to develop a test for pulp vitality has had a somewhat convoluted history, as the concept of 'vitality' has been the pivotal focus of interpretation, misinterpretation, and empirical dogma, especially when using electrical stimulation. Some researchers attempted histological correlations while others focused exclusively on radiographic correlations to validate electrical methods of pulp testing. Some the early literature rightfully focused on the concept of sensibility (a contemporary term in common usage) instead of vitality. This article will purposefully focus on some of the early thought processes of our forefathers as they attempted to arrive a full-proof method to assess the status of the often-compromised dental pulp.

The dental historical literature is replete with the use of myriad of materials for root canal obturation; most notably, gutta-percha, silver cones, gold wires, orangewood sticks, gold foils, asbestos, a variety of paste/cement-type materials, iridioplatinum wires, lead points and a rather lengthy list of arbitrarily chosen substances based on the imagination and creativity of the treating professional.¹.

Dental history is abundantly imbued with personalities and events that are intertwined to form an amazing mosaic of life and its evolution to our present day. One such meaningful reflection on this evolution comes from our President, Dr. Andrew Spielman, who was one of the recipients of the Hayden-Harris Award during the 71^st meeting of the American Academy of the History of Dentistry, in New York city, October 2022. As editor of this Journal, I felt it necessary to share with you his reflections that epitomize our historical richness. -JLG.

Quite often in today's contemporary literature, phrases, or statements such as, or similar to the following, are often seen at the beginning of published manuscript, 'despite several microscopic and histochemical studies, the exact cause…is largely unknown…or is elusive…or has not been fully characterized.' Often these types of statements are used as a justification or a rationale for the published paper that follows. However, when looking carefully at the purported issue or issues at hand, there usually is an historical trail to follow that requires a passionate inquisitiveness, an intellectual persistence, and a monumental determination to find the truth…but even what is discovered in this relentless pursuit may not necessarily represent the truth that may remain elusive. Hence, this historical exposé will focus on a specific issue about a little tissue that most contemporary authors have passed off as a mysterious, unknown entity - the Pulp Stone/Nodule. From 1969 to 2021, there have been over 100 publications or more that have addressed pulp stones purely from an epidemiological or management standpoint, with minimal to no effort to identify their true source or etiology, which may be locked in the vaults of antiquity. However, our forefathers had a pretty good handle on these entities as this historical perspective will address.
