ADAA View Course


It is difficult to believe that preventive dentistry has only been in practice for over one hundred years in the United States. In those 100 years we have seen advances in our delivery of professional oral health care in all disciplines. 

However, despite these advances, dental caries remains the most prevalent chronic disease in both children and adults, even though it is largely preventable. Although caries has significantly decreased for most Americans over the past five decades, large disparities remain among some population groups. In addition, this downward trend has recently reversed for young children.Currently dental caries affects more than 25% of U.S. children aged 2-5 years and approximately 50% of children 12-15 years old. One fourth of adults aged 65 and older are endentulous.

Each year more than 9,000 Americans die from oral and pharyngeal cancers and about 49,670 new cases of oral cancer will be diagnosed this year (2018).2  This course  includes preventive topic areas that are important for the dental professional to know as they care for their patients.
