Publication of dental textbooks was a thriving business years ago and multiple publishing house entered the work place. Historical reflections on one of the early dental publishers coming in Philadelphia over 100 yrs ago are highlighted.

Few in the UK, let alone foreigners understand the British Parliamentary system and the nobility. This paper outlines the origins and roles of the Houses of Commons and Lords. It discusses the hereditary system and an important development, Life Peerages. In particular it showcases the life of a Australian dentist who became a Life Peer, Baroness Gardner of Parkes.

The modern theory of complete denture retention using suction was applied to wooden plate dentures in Japan from the first half of the 16th century, which is an astonishing achievement since it was clinically applied in North America and Europe in the latter half of the 19th century nearly 300 years later. Wooden dentures are unique to Japan resulting from skilled Japanese craftsmanship and are not found in other countries. We comprehensively reviewed reports on wooden plate dentures, analyzed 145 complete and partial dentures, and discussed their history. Japanese wooden plate dentures are mainly made of box wood, and artificial teeth are made of pagodite, ivory, and natural teeth. Small nails were driven into the molar region. Many existing dentures revealed attrition on the occlusal faces, thereby indicating that the wearers were able to masticate sufficiently. Wooden plate dentures have been used for 400 years in the early 20th century. Although Japanese wooden dentures have not been mentioned in the history of dentistry in Western literature, they comprise an important part of the history of denture development.

A unique type of advertising trade card was popular in Europe, mostly Belgium, between 1840 and 1865. These cards were produced with a coating of a white lead substance that gave them a lustrous appearance and feel, resembling porcelain. As attractive as these cards were, producing them oftentimes resulted in lead poisoning for the printers, so few were produced after 1865. "Les cartes porcelaine" were created for a wide variety of products and services, including dentists, and are desirable collectibles to this day.

Dental education today tends to focus on what is provided online in the form of curriculums, handouts, circulated student notes. and mock tests, along with videos from various sources, some of which can be questionable. Often today's dental students choose not to attend lectures as information is supposedly gleaned from the above sources. What is all but absent for the student is a focus on dental books and literature as the main source of their educational process. The present generation will therefore not be labeled as were the students at the turn of the 20 century who may have been erroneously identified as bookworms [124-yr Editorial Below - Dominion Dental Journal 1900;12(12):411]. However, current pedagogical endeavors appear to suffer from the same historical issues as those in the late 1800s and early 1900s with a total focus on mechanical skills without the in-depth exploration and understanding of the science and rationale for such applications. Is it true that we are now training, as opposed to educating, Doctors of Mechanical Dentistry (DMD) and not "journal/bookworms?" The future will tell!

The impact of ground-breaking research on the dental pulp and its response to dental procedures, materials and associated diseases significantly influenced the evolution and scope of Endodontics, creating a science of Endodontology. While there were scattered studies in the early 20^th century in this regard, the clarification and codification of these concepts took a major leap forward in the late 1950s due to the academic prowess and in-depth research endeavors of Dr. Kaare Langeland. The story begins during World War I in Norway.

A full account of early research that led to the discovery of the Alpha-diketone and Amine systems by two Imperial Chemical Industries (ICI) researchers. UK Chemists in the mid-sixties marked the beginning in the early development of a composite resin cured with visible light spectrum into a solid mass. Its incorporation into the newly developed Urethane based resin, led to conceiving the idea of developing the first light-activated restorative composite resin, which formed the prototype of modern composite restorative materials. How all that came about, and the ideas that were conceived and pursued in the development of these systems are discussed in detail.

"See Your Dentist Twice a Year" is the standard of care today honored by dentists, requested by patients, and covered by insurance. Where is the scientific evidence to support this dictate? Several systematic reviews could find no support for or against it. When did it start? This paper traces the timeline of the statement and its appearance in toothpaste advertisements. It was first spotted in 1890 as part of a household guide for beauty preservation. Subsequently, the idea became a tagline in dental advertisements for Colgate Ribbon Toothpaste, Dr. Lyon's Dentifrice from 1913, and Pepsodent toothpaste starting in 1926.

A full account of the preceded early research tribulation that led to the development of the first visible light activated composite resin and the first visible light activator source is documented. The events took place over four years since early 1974 when a raw industrial composite resin that was radiolucent, stiff paste, universal optically opaque white color, polymerized by exposure to a prototype visible light for 120 seconds was given to developed. Four years later, the developed restorative composite resin ended up as a radiopaque, optically translucent, universal color with an additional three shades that possessed the biologic, esthetic, mechanical and physical characteristics with proven efficacy be used for esthetic zone. This conservative account of early development of a technology that must count as one of a small number of inventions during the seventies, over the years has revolutionized restorative dental practice. We were privileged and very lucky to be associated with developmental stages, stumbling blocks, and final success of the first LC Composite resin that ignited the thought process worldwide and laid the foundation for modern esthetic restoratives practiced today.
