Which of the following is NOT one of the 9 dental specialties?

Radiology is not recognized as one of the nine dental specialties by the American Dental Association (ADA). While radiology is an important aspect of dental practice and is critical for diagnosis and treatment planning, it is considered a subspecialty rather than a full specialty. The ADA officially recognizes specialties such as Dental Public Health, Pediatric Dentistry, and Orthodontics among others, each with specific training and certification requirements. Dental Public Health focuses on community dental health, Pediatric Dentistry centers on the care of children, and Orthodontics deals with the diagnosis and treatment of dental and facial irregularities. The distinction between specialty and subspecialty is crucial in understanding the structure of dental education and practice within the field.
