Dental anesthesiology is the specialty of dentistry that deals with research regarding biological reactions and the control of invasion in the oral and maxillofacial areas. Invasions include tissue damage in the oral and maxillofacial areas, inflammation, physical stressors such as pain, psychological stressors such as fear and anxiety, and social stressors from the social environment as a background factor. Drug therapy, especially anesthesia, is an effective method of controlling these invasions. Dental anesthesiology is positioned as an independent field dealing with invasion and biological reactions in the oral and maxillofacial areas.

Dental anesthesiologists are dentists specializing in invasion control in the oral and maxillofacial areas such as anesthesia, physical control, pain clinic, and emergency care.
