INTRODUCTION: During the 'Circuit Breaker' period of the COVID-19 pandemic in Singapore from April to June 2020, governmental policies restricted the practice of dentistry nationwide to the provision of emergency treatment only, regardless of the patient's COVID status. As such, teledentistry was used as an alternative means to continue providing some form of dental care to COVID-19–positive patients who were admitted to a COVID-19 Community Care Facility. DESCRIPTION: The patients were physically triaged by physicians who would send clinical photos to the author via a messaging application, who would in turn triage the patients and assess if they required referral for emergency dental treatment. For patients who did not meet the criteria for referral, the author would advise the physicians on the subsequent management plan which included, but was not limited to, the provision of symptomatic relief. CONCLUSIONS: This article shows the feasibility of undertaking teledental consultations using clinical photos transmitted via a messaging application. The practical implication is a reduced barrier for patients and healthcare professionals to access teledentistry, without having to resort to sophisticated equipment. Hopefully, this will translate into the continued provision of some form of dental care to patients during the ongoing pandemic as opposed to no care at all.

AbstractAs an important breakthrough in coordinating economic, social, and ecological benefits, green innovation has received wide attention from governments, firms, and the public. However, existing studies mainly explored the economic factors influencing firms' green innovation while neglecting social factors. This study took common institutional ownership as the research perspective to explore whether firms' green innovation decisions are affected by their peers. Using a sample of Chinese A‐share listed firms from 2003 to 2019, this paper found that firms imitate their peers' green innovation in common institutional ownership networks and exhibit green innovation peer effects. Mechanism testing revealed that "voting with hands" through common institutional ownership helps firms obtain green innovation information (information‐based imitation), while "voting with feet" through common institutional ownership helps firms maintain a competitive awareness of green innovation (rivalry‐based imitation), thereby contributing to green innovation peer effects in common institutional ownership networks. Heterogeneity analysis showed that firms with greater financing constraints and lower levels of risk‐taking are more likely to imitate their peers' green innovation. Moreover, firms only regard peers with similar industry status and identical property rights as imitation targets in common institutional ownership networks, thereby following "the imitation law of closer preference." An analysis of economic consequences revealed that green innovation peer effects in common institutional ownership networks are not strategic behaviors of "quantity over quality," with imitation contributing to improving firm value. This paper enriches existing research on the influencing factors of green innovation and provides a new reference for promoting sustainable development.

Nanoscience enables researchers to develop new and cost-effective nanomaterials for energy, healthcare, and medical applications. Silver nanoparticles (Ag NPs) are currently increasingly synthesized for their superior physicochemical and electronic properties. Good knowledge of these characteristics allows the development of applications in all sensitive and essential fields in the service of humans and the environment. This review aims to summarize the Ag NPs synthesis methods, properties, applications, and future challenges. Generally, Ag NPs can be synthesized using physical, chemical, and biological routes. Due to the great and increasing demand for metal and metal oxide nanoparticles, researchers have invented a new, environmentally friendly, inexpensive synthetic method that replaces other methods with many defects. Studies of Ag NPs have increased after clear and substantial support from governments to develop nanotechnology. Ag NPs are the most widely due to their various potent properties. Thus, this comprehensive review discusses the different synthesis procedures and electronic applications of Ag NPs.
