People are constantly studying and exploring teeth and oral and maxillofscial anatomy in order to understand and treat dental and oral and maxillofacial diseases.As early as 2000 years ago,people were partially aware of oral topography,but not until the Renaissance was a breakthrough made.In 1728,a dental professional book,"Surgical Dentist,"was published,which marked dentistry as an independent discipline.Thereafter,John Hunter published"The Natural History of Human Teeth"(1771)and the "Actual Dissertation on Dental Disease"which marked the birth of dental anatomy.By modern times,dental and oral and maxillofacial anatomy has developed rapidly due to the use of a variety of science and technology and the progress in medicine.
