Final answer:
Oral and maxillofacial surgery is the dental specialty that focuses on surgical treatments of the oral region.
Step-by-step explanation:
The dental specialty that deals with the diagnosis and surgical treatment of the oral region is known as oral and maxillofacial surgery. This specialty is distinct from other dental areas such as orthodontics, periodontics, and endodontics, focusing specifically on surgical treatments rather than braces, gum disease, or root canals. Oral and maxillofacial surgeons are trained to address various issues, such as impacted teeth, facial pain, TMJ disorders, misaligned jaws, as well as reconstructive surgery following trauma or disease.
