Dental technology of Taiwan during the Japanese colonial period.

Background/purpose: During the Japanese colonial period, the Taipei Hospital had already provided complete dental services with a fixed price per treatment. This study tried to compare the differences in the prices of various dental treatments between the Japanese colonial period and today. Materials and methods: This study used the "Dental Treatment Fees in the 27th Annual Report of Taipei Hospital (Taisho 12)" as the study materials to compare the differences in the prices of various dental treatments between the Japanese colonial period and today using the monthly salary of a novice elementary school teacher as an income benchmark. Results: A hundred years ago, the Taipei Hospital had already provided the dental treatments such as scaling and endodontic, operative dentistry, prosthodontic, and orthodontic treatments. Of these treatment items, the prices for prosthodontic and orthodontic treatments were more expensive. After a century of development, the costs of scaling and operative dentistry treatments dropped, while the costs of endodontic, prosthodontic, and orthodontic treatments increased. Conclusion: During the Japanese colonial period, Taiwan's dental treatment technology had already had the forms of modern dentistry with several dental specialties. At that time, the costs of dental treatments are quite expensive. Today's dental treatment items are more detailed and diverse. The health insurance system provides Taiwanese people with convenient and cheap general dental treatments such as scaling and treatments related to operative dentistry, endodontics, periodontics, and oral surgery. However, the costs of prosthodontic and orthodontic treatments increase and have to be paid by the patients themselves.

Dental education and special dental practitioner-cultivating system in Taiwan during the Japanese colonial period.

Background/purpose: During the Japanese colonial period, Taiwan had no dental school but had a medical school. This study explored the dental education and research activities in the medical school and special dentist qualification system in Taiwan during the Japanese colonial period. Materials and methods: This study analyzed the "related incidents and documents of dental education and research and dentist qualification system in Taiwan during the Japanese colonial period" and explored the dental education and research activities in the medical school and special dentist qualification system in Taiwan during the Japanese colonial period. Results: In 1914, Taiwan Government Medical School hired Dr. Kaname Ansawa, the earliest dental teacher in Taiwan, to teach dental courses in the medical school. In 1918, the "Theory of Dentistry" was considered to be the first independent "Dentistry" subject in the medical school. In 1936, the Faculty of Medicine of Taipei Imperial University listed "Dentistry & Oral Surgery" as an independent graduation examination subject. For dentist qualification system, a qualified physician who had finished dental courses and training could apply for a dental specialty license to work as a dentist. Taiwan Government Medical School (Dentistry) Research Department was the earliest department involved in the teaching and research of dentistry in the medical school and was also an educational institution for cultivating dental practitioners in Taiwan. Conclusion: In the Japanese colonial period, although no dental school was established in Taiwan, there were rich dental education and research activities in the medical school and a special dentist qualification system.

Development of dental education for medical students in Taiwan during the Japanese colonial period.

Background/purpose: During the Japanese colonial period, Taiwan had a medical school education system for cultivating physicians, but did not have a dental school education system for cultivating "real" dentists. In this investigation, we collected and analyzed the historical documents related to dental education to study the development of dental education for medical students in Taiwan during the Japanese colonial period. Materials and methods: This study mainly analyzed the changes in the development of dental education for medical students in Taiwan during the Japanese colonial period through the collection and sorting of relevant historical materials. Results: During each stage of Taiwan's medical education system in the Japanese colonial period, the medical school offered compulsory dental courses for medical students, including theory and clinical practice of dentistry. Although there was no specific dental subject included in the graduation examination, evidence showed that the content of dentistry was covered by the subject of Surgery in the examination. Moreover, Taipei Imperial University established the Medical Faculty in 1936. Its curriculum increased the weight of dentistry and added the "Dentistry & Oral Surgery" as a graduation examination subject, indicating the importance of dental education for medical students in that period. Conclusion: In the Japanese colonial period, although there was no dental school for cultivating dentists in Taiwan, there was still dental education for medical students to let them understand the Dentistry and to enable them to become dental practitioners. This can be regarded as a workaround in the medical and healthcare policy.

Dental manpower and treated dental diseases in department of dentistry, Taipei Hospital (the predecessor of National Taiwan University Hospital) in 1923.

BACKGROUND/PURPOSE: In 1906, there was a dental treatment room established in the department of surgery of Taipei Hospital to introduce modern dental services to Taiwan. It is undoubtedly the earliest hospital dentistry in Taiwan. This study tried to assess the dental manpower and treated dental diseases in Taipei Hospital, and hence to explore the appearance of Taiwan's early hospital dentistry. MATERIALS AND METHODS: This study utilized the secondary data analysis to evaluate the dental manpower and treated dental diseases of dental outpatients in the 27th Annual Report of Taipei Hospital (Taisho 12th year or 1923). RESULTS: Our results found that there were 3 dentists and one dental technician in the dental department of Taipei Hospital in 1923. These 3 dentists totally treated 3 inpatients and 1759 outpatients with 4511 outpatient visits (1959 for male patients and 2552 for female patients) in that year. Dental caries and retained root were the two most common dental diseases in Japanese and Taiwanese dental outpatients, and followed in a descending order by missing tooth, pulp necrosis, and pulpitis for Japanese outpatients as well as pulpitis, suppurative periodontitis, and acute or chronic periodontitis for Taiwanese outpatients. CONCLUSION: We conclude that the dentistry of Taipei Hospital in 1923 does have a modern form of dentistry with 3 dentists and one dental technician. Its dental patients are mainly Japanese and minorly Taiwanese. Moreover, the treated dental diseases are mainly tooth diseases for Japanese outpatients and both tooth and periodontal diseases for Taiwanese outpatients.
