It seems that the last time I looked, Jim Avery and I were working on editing the third edition of Essentials of Oral Histology and Embryology: A Clinical Approach, and now I am completing the sixth edition. It’s truly amazing that time seems to travel at the speed of light the more you have to accomplish.  the sixth edition has many changes from previous editions. One of the major additions is a section on viruses of the oral cavity.  the stimulus for this section was the COVID-19 pandemic the world is/was experiencing. Viruses of the oral cavity have been playing an increasingly more common role in the various pathologies of the mouth. Before COVID, herpes simplex 1 was diagnosed with increasing frequency.  then came human papillomavirus and finally, COVID. Of course, this is a simplistic timeline, but the world was changed. Today, we live with the new guidelines for prevention of and protection from a virus that didn’t exist in its present form until recently. In a very short amount of time, a vaccine was developed and administered to the world. We are all grateful to the many different professions and healthcare providers who worked together to develop and administer the vaccine.  there was some turmoil and trepidation in between, but the outcome was as good as or better than predicted.  throughout the sixth edition, there have been many editorial changes that clarify and enhance the subject matter of each chapter, including new references. I sincerely hope that the reader—whether that be a student, instructor, or interested lifelong learner—finds this edition easy to read and informative.
