Final answer:
Aesthetic dentistry is focused on enhancing the visual appearance of teeth, which is a true statement. However, procedures like the replacement of a partial denture can fall under both aesthetic and restorative dentistry, as they can serve to improve both function and appearance.
Step-by-step explanation:
The statement that aesthetic dentistry is primarily devoted to improving the appearance of teeth is true. The purpose of aesthetic, or cosmetic, dentistry is to enhance the visual aspects of a person's teeth, which can include various treatments such as whitening, veneers, and orthodontics. However, while the replacement of a partial denture can be considered under the purview of aesthetic dentistry if the goal is to improve the appearance of one's smile, it is essential to note that it also falls under restorative dentistry, which focuses on functionality and repairing dental issues in addition to improving aesthetics.
