World Oral Health Day is an annual event held on March 20 to raise awareness about oral health and highlight the importance of maintaining good dental hygiene across the world. To commemorate this occasion, we have selected 9 papers on oral health published in Antioxidants (ISSN: 2076-3921) since 2024 that present the latest research and insights in this field. We hope that you find them informative and engaging.
