Limited research has been undertaken in Australia to assess the dental status of pre-school Aboriginal children. This cross-sectional study records the number of decayed, missing and filled teeth (dmft) and surfaces (dmfs) of pre-school Aboriginal children living in different locations in New South Wales (NSW), Australia.
A convenience sample of young children from seven Aboriginal communities in rural, remote and metropolitan areas of NSW, was recruited. One calibrated examiner recorded the dmft/s of children with written parental consent.
196 children were invited to participate and 173 children aged two to five years were examined, a response rate of 88.3%. Forty percent (n = 69) of the children were diagnosed with dental caries with a mean of 2.1 (SD = 3.6). The dmft scores were significantly higher in remote locations when compared to rural (p = <0.0001) and metropolitan areas (p = 0.0155). Children 4-5 years old living in remote NSW had a mean dmft of 3.5 and mean dmfs of 8.0 compared with children living in rural areas who had a dmft and dmfs of 1.5 and 4.2 respectively. Untreated dental caries was the primary contributor to the scores, and children who had previously received dental treatment still had active carious lesions.
There was a high prevalence of untreated dental caries among the Aboriginal children, particularly for those in remote locations.
澳大利亚针对学龄前原住民儿童的口腔状况开展的研究有限。这项横断面研究记录了居住在澳大利亚新南威尔士州（NSW）不同地区的学龄前原住民儿童的龋失补牙数（dmft）和龋失补牙面数（dmfs）。
选取了新南威尔士州农村、偏远和大都市地区七个原住民社区的幼儿作为便利样本。在获得家长书面同意后，由一名经过校准的检查人员记录儿童的dmft/s。
共邀请了196名儿童参与，检查了173名2至5岁的儿童，应答率为88.3%。40%（n = 69）的儿童被诊断患有龋齿，平均龋齿数为2.1（标准差 = 3.6）。与农村地区（p = <0.0001）和大都市地区（p = 0.0155）相比，偏远地区儿童的dmft得分显著更高。居住在新南威尔士州偏远地区的4至5岁儿童平均dmft为3.5，平均dmfs为8.0，而居住在农村地区的儿童dmft和dmfs分别为1.5和4.2。未治疗的龋齿是得分的主要因素，且之前接受过牙科治疗的儿童仍有活动性龋损。
原住民儿童中未治疗龋齿的患病率很高，尤其是偏远地区的儿童。
