As the coronavirus disease (COVID-19) pandemic continues to sweep across the globe, the world is responding by implementing public awareness campaigns, social distancing measures, and other preventive strategies to arrest the spread of this lethal disease. Infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exacts a heavy toll on patients with existing comorbidities. Smokeless tobacco (SLT) consumption is of particular concern in countries in South Asia with high population densities, as it facilitates exposure to SARS-CoV-2 within or between communities by the act of public spitting. Salivary droplets generated in this act are a potential threat because they can transmit this airborne infection. Moreover, large gatherings at tobacco retail outlets, frequent hand-to-mouth contact, and sharing of apparatus by SLT habitués could also aid in increasing the spread of SARS-CoV-2. SLT-induced higher expression of angiotensin-converting enzyme 2 receptors along with the presence of furin in the oral mucosa and dysfunctional immune responses among SLT habitués increase viral dissemination and an individual's susceptibility to COVID-19. Issuing rigorous regulations to restrict the use of various forms of SLT products and the obnoxious act of spitting in public can assist in arresting the spread of COVID-19. Widespread education campaigns enlightening the community regarding the adverse effects of SLT consumption and its relationship with COVID-19, along with providing effective assistance to quit for those who are addicted, would decrease the spread of COVID-19.
The success of removable prostheses ultimately depends on a number of factors such as retention, stability, support, esthetics, and masticatory function. Increased intraoral inter-arch distance leads to an increase in the weight of the prosthesis. This may compromise the retention and resistance, which are key for a successful removable prosthesis. Various methods, techniques, and materials have been reported to minimize the weight of a prosthesis. This article describes a simple, unique, precise single-flask technique for the fabrication of a lightweight maxillary prosthesis using caramel as a 3D spacer, which was "indexed" to obtain a uniform thickness of acrylic around the hollow cavity.
Making impressions in microstomia patients is often cumbersome. A modification of standard impression procedure is often necessary while treating such patients. This article describes the fabrication of a custom sectional impression tray with interlocking type of a handle for definitive impression procedures in a microstomia patient.
This article describes a technique for repair of abutment tooth which fractured during removal of a provisional restoration before bisque trial. The technique uses plastic templates to fabricate new composite core foundation for the existing crowns. This technique helps the dentist to rebuild the core in a single appointment.
2020, the World Health Organization (WHO) announced that the COVID-19 outbreak constituted an international public health emergency[1]. To prevent an upsurge in the number of cases across India, the central government imposed a nationwide lockdown that was initially scheduled from March 25 th to April 14 th , 2020, but which was eventually extended until May 31 st , 2020, with progressive changes in restrictions [2][3][4]. As the lockdown did not cover the national healthcare system, medical and dental hospitals remained functional, but all nonessential services were suspended. Meanwhile, the government gradually lifted the lockdown over several phases referred to as "unlock periods."This is an open-access article distributed under the terms of Creative Commons Attribution-NonCommercial License 4.0 (CC BY-NC 4.0), which allows users to distribute and copy the material in any format as long as credit is given to the Japan Prosthodontic Society.

Helical keloids are difficult to treat as surgical excision requires effective compression of the operative scar to prevent recurrence while retaining the contour and elasticity of the helix. The authors fabricated a conforming custom made post-operative splint from a commonly used dental material. Splints could be fabricated in both pre-operative and post-operative stage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
