What is the most dentally relevant virus?

The most dentally relevant virus is the human papillomavirus (HPV), particularly certain high-risk strains associated with oropharyngeal cancers. HPV can lead to lesions in the oral cavity, such as oropharyngeal squamous cell carcinoma, highlighting its importance in dental health. Additionally, herpes simplex virus (HSV) is significant in dentistry due to its association with oral lesions like cold sores. Regular dental check-ups can help in the early detection and management of these viral infections.
