On behalf of the authors, readers, and editorial board members of Restorative Dentistry and Endodontics (RDE), I wish to thank everyone who reviewed manuscripts for our journal in 2019 from the bottom of my heart. RDE could not publish these valuable scientific papers without the contributions of reviewers, who invest considerable time and effort into the review process. As in previous years, RDE has presented Achievement Awards and Certificates of Appreciation to members of the Editorial Board and reviewers in gratitude for their contributions. With deep gratitude, I would like to acknowledge the award recipients. Prof. Yeon-Ji Yoo and Prof. Minju Song were selected to receive Achievement Awards to recognize their dedication as associate editors. Certificates of Appreciation were awarded to the following 5 reviewers: Prof. Taha Özyürek, Prof. Mariko Matsumoto, Prof. Sangwon Kwak, Prof. Jin-Young Ryan Kim, and Prof. Soram Oh. We would also like to thank all of our reviewers and humbly request their ongoing interest and support in 2020.
