To compare the socioeconomic profiles of children registered in the GDS, with those using the CDS services and unregistered children. Secondly to examine the effects of socioeconomic status on travelling to access primary dental care, and finally to map out the location of unregistered children in relation to primary dental care services.
The study was carried out in 1998 in Ellesmere Port in the North West of England.
The study population was all children younger than 6 years who used primary dental care services in, or were residents of, Ellesmere Port. The study population was categorized into those registered with a GDS dentist, those using CDS services and those unregistered by matching GDS and CDS data to the HA population register. Socioeconomic status was measured using the Super Profiles geodemographic classification. The relationship between service preferences and travelling to access primary dental care with socioeconomic status were compared using cross-tabulations and chi square tests.
There was a significant socioeconomic trend evident in the use of dental services. Two thirds of those using CDS services came from the most deprived area types. Of those who were unregistered half lived in the most deprived area types compared with one third of those registered with the GDS. Those who travelled into Ellesmere Port to access primary dental care were significantly more likely to live in an affluent area. Unregistered patients were homogeneously spread across the town.
The ability to match GDS and CDS data to the HA population register is essential to understand how dental services are used by the local population. Children from deprived areas are more likely to use the CDS and a service local to their homes, therefore primary dental care services for deprived communities have to be provided locally.
比较在一般牙科服务（GDS）注册的儿童、使用社区牙科服务（CDS）的儿童以及未注册儿童的社会经济概况。其次，研究社会经济地位对前往接受初级牙科护理的影响，最后，确定未注册儿童相对于初级牙科护理服务的位置。
该研究于1998年在英格兰西北部的埃尔斯米尔港进行。
研究人群为所有6岁以下、在埃尔斯米尔港使用初级牙科护理服务或居住在该地区的儿童。通过将GDS和CDS数据与健康管理局（HA）人口登记册进行匹配，将研究人群分为在GDS牙医处注册的儿童、使用CDS服务的儿童和未注册儿童。使用超级概况地理人口统计学分类法衡量社会经济地位。使用交叉表和卡方检验比较服务偏好以及前往接受初级牙科护理与社会经济地位之间的关系。
在牙科服务的使用方面存在明显的社会经济趋势。使用CDS服务的儿童中有三分之二来自最贫困的地区类型。在未注册儿童中，有一半生活在最贫困的地区类型，而在GDS注册的儿童中这一比例为三分之一。前往埃尔斯米尔港接受初级牙科护理的儿童更有可能生活在富裕地区。未注册患者在全镇分布均匀。
将GDS和CDS数据与HA人口登记册进行匹配的能力对于了解当地居民如何使用牙科服务至关重要。贫困地区的儿童更有可能使用CDS以及当地的服务，因此必须在当地为贫困社区提供初级牙科护理服务。
