The history of dental literature features renowned authors like Bartolomeo Eustachio (1562), Ambroise Paré (1570), and Pierre Fauchard (1728), yet little is known about early female contributors. This study explores a groundbreaking work by Mademoiselle De Rezé, a French author who, in 1719, published Dissertation Apologétique de Remèdes (Humble Treatise on Remedies), the first known text on dental remedies authored by a woman. Mademoiselle De Rezé detailed proprietary dental remedies-Universal Balm, Tincture, and Tooth-Whitening Powder-used to address toothaches, gingival ulcerations, and halitosis. Her formulations reportedly cured the Madame le Dauphine and praised by King Louis XIV gaining popularity over 40 years. While the exact composition of these remedies remains unknown-a common practice at the time-testimonials of their efficacy solidify their historical significance. This study highlights the overlooked contributions of Mademoiselle De Rezé, whose Dissertation Apologétiques de Remèdes merits recognition in the history of dentistry as a vital early text authored by a woman.

"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.

This position paper explores the historical transitions and current trends in dental education and practice and attempts to predict the future. Dental education and practice landscape, especially after the COVID-19 epidemic, are at a crossroads. Four fundamental forces are shaping the future: the escalating cost of education, the laicization of dental care, the corporatization of dental care, and technological advances. Dental education will likely include individualized, competency-based, asynchronous, hybrid, face-to-face, and virtual education with different start and end points for students. Dental practice, similarly, will be hybrid, with both face-to-face and virtual opportunities for patient care. Artificial intelligence will drive efficiencies in diagnosis, treatment, and office management.

Pierre Fauchard, considered the father of dentistry, contributed to the development of different fields of dentistry that we know today. However, the contribution of this important individual to the fields of oral medicine and oral and maxillofacial pathology is unknown. This study aimed to identify Pierre Fauchard's contribution to these areas of dentistry. We focused on "Le Chirurgien Dentiste, or Traité des Dents" in both French and English, looking for information about the oral diseases diagnosed and treated by Fauchard. Information on patient history, disease description, treatment applied, and clinical follow-up was collected. A contemporary analysis of the diseases was performed, and the collected data were systematized, reported, and analyzed descriptively, according to the current literature on the addressed topics. Information on conditions such as scurvy, parulides, epulides, oral ulcers, dentoalveolar abscesses, dental alterations, and post-exodontia incidents were elucidated. Findings indicated that Pierre Fauchard described, diagnosed, and treated different soft and hard tissue diseases of great interest to the fields of oral medicine and oral and maxillofacial pathology.

History of Dentistry starts from the moment the Late Paleolithic Man used a toothpick fashioned from a bone or wood splinter, or the moment our human ancestors began to manipulate the surface of a tooth to remove its retentiveness, so food does not get stuck. That was at least 14,000 years ago, based on available evidence. The current timeline, compiled in this article, is one of many published over the years. However, this timeline incorporates three new strategies. First, it extends to select medical and fundamental dental discoveries, as the History of Dentistry can only be told with the main events within the History of Medicine. Second, it is more detailed (350 entries) than any previous timeline the author has encountered. Third, several critical primary references to support events listed in this timeline characterize this effort. Finally, 130 illustrations are included to improve the visualization of dates. The manuscript also includes a new display of the five main stages of dentistry throughout its history.

Responses to capsaicin are reduced following repeated exposure, a phenomenon known as capsaicin desensitization. Heavy consumers of chilies consistently report reduced oral burn relative to infrequent consumers, presumably due to chronic desensitization. However, the mechanism(s) underlying capsaicin desensitization remain poorly understood. We hypothesized that reduced response to capsaicin due to repeated oral exposure may result from a change in the expression of the capsaicin receptor (TRPV1) gene. To test this, we conducted two longitudinal desensitization studies in healthy human volunteers. In Study 1, 51 adults completed a 17-day capsaicin desensitization protocol. The study consisted of three in-person visits where they were asked to sample stimuli, including 3, 6, and 9 ppm capsaicin, and rate intensity on a general labeled magnitude scale (gLMS). Between days 3 & 17, participants rinsed at home with 6 ppm capsaicin (n = 31) or a control (n = 20) solution (20 uM sucrose octaccetate; SOA) twice a day. Before and after the oral exposure protocol, a clinician collected fungiform papillae. Participants randomized to the capsaicin rinse showed a statistically significant reduction in oral burn ratings that was not observed in controls, indicating repeated low-dose exposure can systematically induce desensitization. TRPV1 expression was not associated with reported capsaicin burn, and there was no evidence of a decrease in TRPV1 expression following capsaicin exposure. In Study 2, participants (n = 45) rinsed with 6 ppm capsaicin in a similar protocol, rating capsaicin, vanillyl butyl ether (VBE), cinnamaldehyde, ethanol, menthol, and sucrose on days 1, 3, & 17. Burn from capsaicin, VBE, cinnamaldehyde, and ethanol all showed a statistically significant change - capsaicin, VBE and cinnamaldehyde burn all dropped ∼20 %, and a larger reduction was seen for ethanol - while menthol cooling and sucrose sweetness did not change. Collectively, this suggests reductions in oral burn following chronic capsaicin exposure generalizes to other stimuli (i.e., cross desensitization) and this cannot be explained by a change in TRPV1 mRNA expression. More work is needed to elucidate the underlying mechanism for capsaicin desensitization in the oral cavity.
