Which of the following is a listed specialty?

• A. Cosmetic Dentistry
• B. Sleep Medicine
• C. Periodontics
• D. Orthodontics

Answer: (C)

In dentistry, a listed specialty is a field that requires advanced, formal training beyond the general dental degree and is officially recognized as a distinct area of expertise. Periodontics fits this because it concentrates on the gums and the supporting structures around teeth, including disease management and treatments like implants. Practitioners complete specialized residency programs and obtain board certification to be recognized as periodontists. This combination of a focused clinical area and certified advanced training is what makes it a listed specialty. The other options describe services or medical fields that aren’t recognized as formal dental specialties in the same way, which is why periodontics stands out as the listed specialty here.
