SEOUL, South Korea: Even though intra-oral scanners have been around for more than three decades and their use in dental practice is increasing, few investigations have evaluated the 3D accuracy of digital implant scans. As discrepancies between implant components must be minimal, researchers from Seoul National University School of Dentistry have evaluated the trueness of ten intra-oral scanners in determining the positions of simulated implant scan bodies.
LEIPZIG, Germany: Sustainability in dentistry is more than a trend. It is a reality that businesses of all sizes have to face and find ways to adapt if we are to sustain a liveable planet for generations to come. At first glance, this may seem like an impossible task, because there is so much to consider. What should one do? Where should one start? How much time and money will it cost? There is much to do. But there are many positive changes towards a greener future that can be put in place almost immediately which are inexpensive and sometimes even free. Besides an initial discussion on the topic, this article provides some easy-to-implement hands-on tips and a focus on practice owners who are already successfully practising environmentally friendly dentistry.
With its transformative power, digital dentistry is slowly taking over dental practices and laboratories all around the world. In a free webinar on Feb. 17, prosthodontist Dr. Ryan C.

Prior to his online presentation, he shared some thoughts on the topic.
BRISBANE, Australia: Dental professionals and researchers continue to look for the best solutions to help prevent and manage peri-implant disease. For example, researchers at the University of Queensland School of Dentistry in Brisbane are developing a treatment that will improve dental implant outcomes by preventing bacterial growth and biofilm formation on implant surfaces. The researchers believe that the treatment may also be effective in treating periodontitis.
CHICAGO/EVANSTON, Il., U.S.: The recent development of resins marketed as biocompatible has led to the widespread application of 3D-printable resins, for example in medical devices and tissue engineered constructs. However, researchers from Northwestern University in Chicago and in Evanston have found that two 3D-printable resins for use in dental applications leach compounds that can cause severe toxic effects in the oocyte, the immature precursor to the ovum that can eventually be fertilized.
TEMPE, Ariz., U.S.: Align Technology sold a record 1.6 million cases of clear aligners in 2020—the same year in which most governments and businesses around the world hemorrhaged money while being starved of income. The clear aligner maker did a lot for dentists and orthodontists last year and is now reaping the rewards. Moreover, the digital workflows behind clear aligner therapy are helping dentists and orthodontists to keep patient numbers high.
OPORTO, Portugal: A recently published paper, which is the second of a three-part series on the management of COVID-19 in clinical dental care settings, aims to describe the selection and use of personal protective equipment (PPE) by dental care professionals, based on the level of risk associated with the planned procedures. The researchers emphasise the importance of properly putting on and removing PPE, as well as choosing the appropriate equipment because it can be associated with a risk of infection.

DOHA, Qatar: Since periodontitis and COVID-19 are both associated with systemic inflammation, researchers from Qatar University and Hamad Medical Corporation in Qatar have investigated the connection of periodontitis with severe outcomes of the respiratory syndrome. The study findings supported a link between the two diseases, as COVID-19 patients with periodontitis were more likely to experience complications or to die.
LUCERNE, Switzerland: On 11 February, GC is celebrating its 100th anniversary since it was founded in Japan in 1921. To commemorate this significant milestone, GC has planned a number of both internal and external initiatives throughout the year.

As part of work supported by a series of rapid-response grants for COVID-19-related research, mechanical engineering PhD student Dongjie Jia at Cornell University, U.S., helped develop a design for an open-faced helmet for patient use that is connected to a medical-grade air filtration pump from the top that creates a reverse flow of air to prevent cough droplets from entering the clinic environment. In an interview with Dental Tribune International, Jia explained how this project, which was funded by the Cornell Atkinson Center for Sustainability, was born and how it could help medical professionals in the ongoing pandemic.

LEIPZIG, Germany: New discoveries about COVID-19 are outpacing the nomenclature. Research is emerging that suggests that a large number of COVID-19 patients experience symptoms in the oral cavity that are not yet recognised as typical signs of the disease. Geographic tongue—which is being referred to as “COVID tongue”—has been observed in those with COVID-19, as have herpetic lesions and oral aphthous ulceration.

HARLOW, UK: Now that many questions regarding COVID-19, including its symptoms, risks and recovery time, have been answered, researchers are faced with a new dilemma: SARS-CoV-2 reinfection and immunity. Although unusual, it is evident that reinfections do occur, and in a recent study, researchers explored whether individuals who have recovered from COVID-19 are protected from future infection. The findings suggested that past infection may provide natural immunity and that the said immunity is effective for approximately half a year after the initial infection.

Periodontitis and peri-implantitis are both inflammatory conditions that affect gingival tissue. However, owing to the anatomical differences between teeth and implants, the two diseases require distinct treatments. In a recent interview, Dental Tribune International spoke with Dr Georgios N. Belibasakis, professor of clinical oral infection biology and head of the Division of Oral Diseases at Karolinska Institutet in Stockholm in Sweden, on the topic. Belibasakis has recently co-authored a study on the microbial pathogenesis of peri-implantitis and believes that a deeper understanding of the issue could help develop improved strategies for prevention, diagnosis and treatment.
