Lee and Jung: An exploratory study on development policy and the status of oral health care in the North Korea during the Kim Jong-Un era

Abstract

Objectives

Studies on oral health care in North Korea are being pursued in South Korea. However, the covertness of North Korea offers substantial resistance to the access of information from the country, including in the field of oral health care. In this study, we explored North Korea's oral health care policy and its status in the Kim Jong-Un Era.

Methods

We used existing information from Internet searches and also interviewed three health care professionals who had recently contact with North Korea.

Results

At present, there are four development policies of oral health care in North Korea: expansion of dental institutions and resource support, strengthening the prevention and treatment of dental diseases, improvement of dental prosthetics, and increasing the responsibility and role of the dental workforce. In addition, there has been an increasing interest in children's oral health with the development of a few programs.

Conclusions

In order to improve overall oral health care, cooperation is required from North Korea in accessing relevant information in the field of children's oral health, dental prosthetics, and dental materials. For this to occur, there should be a preliminary trust building process between North Korea and South Korea as well as access to information from reliable sources.

− The rapid increase in dental caries incidence among young generations had alarmed the local authorities to seek foreign cooperation.
Goal ㆍ To reduce dental caries and improve oral health among children and adolescents in the North Korea
Implementation & spread ㆍ Planning and implementation of the COHPP
− The programme was initiated in central Pyongyang city in 2007 and target population was children at kindergarten and primary schools.

− Toothbrushes, fluoride toothpaste and a children’s workbook were provided to the children.
− Supervised toothbrushing was part of the daily schedule at the schools and kindergartens.
− The results were evaluated as part of the research co-operation between the UEF and PMC.
− The programme covered the entire capital area in 2013 and was expanded to Jongju city of North Phy-ongan Province in 2012 and to Sepo Country of Gangwon Province in 2014.
ㆍ Development of dental health services in the cooperation hospitals
− The three cooperation hospitals were situated in downtown Pyongyang. Additionally, some support was provided to Jongju City Hospital.
