目的了解日本提供正畸服务的专业正畸医生和牙医的地理分布情况。方法通过人口普查获得2010年日本1750个城市的人口数据。我们通过参考《医生、牙医和药剂师调查》获得了主要提供正畸服务的牙医(专科正畸医生)和提供正畸服务的牙医(包括普通牙医)的数量的数据。此外，我们参考了日本正畸学会(JOS)网站上的目录，以获得JOS资格的正畸医生的数据。为了评估专业正畸医生和正畸医生的分布，我们使用了洛伦茨曲线和基尼系数。结果每10万名5-40岁的人中，专业正畸医生和JOS认证正畸医生的中位数为0，而正畸提供者的中位数为27.5。专业正畸医生和JOS认证正畸医生的基尼系数分别为0.523和0.615。另一方面，正畸服务提供者的基尼系数为0.258。结论各地区在专科正畸医生的可及性方面存在较大的地区不平等，在城市以外的地区获得专科正畸服务的机会可能受到限制。在人口不到50,000的城市，专业正畸医生的数量很少，但正畸提供者的分布相对均匀。我们的研究结果表明，研究专业正畸医生和正畸提供者的分布可以为制定牙科保健政策提供有价值的信息。
ObjectiveThis study aimed to clarify the geographic distribution of specialist orthodontists and dentists who provide orthodontic services in Japan.MethodsWe obtained data on the populations of 1750 municipalities in Japan in 2010 by referring to the census. We obtained data on the number of dentists who mainly provide orthodontic services (specialist orthodontists) and the number of dentists, including general dentists, who provide orthodontic services (orthodontic providers), by referring to the Survey of Physicians, Dentists, and Pharmacists. Furthermore, we referred to the directory on the website of the Japanese Orthodontic Society (JOS) to obtain data on JOS-qualified orthodontists. To assess the distribution of specialist orthodontists and orthodontic providers, we used Lorenz curves and Gini coefficients.ResultsThe median value for the number of specialist orthodontists and number of JOS-certified orthodontists per 100,000 persons aged between 5 and 40 years old was 0, while that of orthodontic providers was 27.5. Gini coefficients for specialist orthodontists and JOS-certified orthodontists were 0.523 and 0.615, respectively. On the other hand, the Gini coefficient for orthodontic providers was 0.258.ConclusionsRegional inequalities in the availability of specialist orthodontists are high, and medical access to specialist orthodontic services may be limited in areas other than urban districts. In municipalities with a population of fewer than 50,000 inhabitants, the number of specialist orthodontists was very low, but orthodontic providers were relatively evenly distributed. Our research results suggested that studying the distribution of specialist orthodontists and orthodontic providers can provide valuable information for developing dental care policies.
