It is 100 years since the 'Roaring Twenties', a decade of economic growth and widespread prosperity. What will define the 2020s? Hopefully at least some of it will be positive and optimistic!

I asked followers on the BDJ Team Facebook page to reflect on their careers in dentistry to date and what they are looking forward to in the coming years. Opinions ranged from becoming tutors, completing post-graduation certificates and Master's degrees, to moving to a career as a medical nurse, watching the children thrive, continuing in the current vein, improving the planet...and retiring to spend winters in the sun! All of the interviewees in the article 'I continue to learn every day' have had varied experiences and routes through their dental careers so far: I hope that you enjoy reading about them and comparing your own experiences.

This February is a bumper issue. Priya Sharma writes an update on radiation regulations in your practice, a subject often requested by readers for CPD purposes. Janet Pickles explains why relative analgesia, or inhalation sedation, is a safe and valuable asset to today's dental practice. Julie Deverick of BSDHT says that we should all work together to eliminate illegal tooth whitening. We share research published in the BDJ on the dental team's responsibilities surrounding modern day slavery; and on the conflicting demands that dental professionals experience when using social media. We also look at whether children's screen use is associated with their level of caries, a summary review from Evidence-Based Dentistry.

Finally, in a self-reflective log, Charlotte Bowes, a Clinical Fellow in Restorative Dentistry at Newcastle University, explores how people with substance dependency can be engaged in oral health.

Next month I look forward to introducing our new reader panel to you. Each new panellist will be writing a unique article for BDJ Team this year. I can't wait to share them with you!
