本研究的目的是建立流行病学指标的经验，在12岁的学童在城市的库里蒂巴，巴西，探讨其地理和人口分布的牙齿创伤。使用了一个地理信息系统，该系统是通过ArcView GIS 3.2软件和库里蒂巴研究和公共规划研究所提供的库里蒂巴市边界内街道和地区地理数据库建立的。研究中使用的数据库是根据1998年对居住在库里蒂巴市29个微型地区的边远城市郊区的2 126名12岁学龄儿童进行的流行病学调查编制的。本研究选择的病例是那些有牙齿外伤史的病例，因此包括327名学童的子样本。学校儿童的住所的空间位置使这些事件能够在地图的基础上形象化。在分析和绘制专题地图时纳入了性别、创伤病因和生活条件不达标地区等变量，从而能够对该市牙创伤的空间分布进行描述性分析。在库里蒂巴12岁学龄儿童的牙齿创伤患病率方面，发现了城市内部的差异。在该市东部地区，特别是在生活条件低于标准的地区，发生的事件更为集中。可以得出结论，社会环境和地球物理因素与库里蒂巴市牙齿创伤的确定有关，指出需要制定特别针对风险较大的地区和人口的公共政策。
The purpose of this study was to build epidemiological indicators on the experience of dental trauma in 12-year-old schoolchildren in the city of Curitiba, Brazil, exploring its geographical and population distributions. A geographic information system (GIS) was used, built by means of ArcView GIS 3.2 software and geographical databases of streets and districts defined within the boundaries of the city of Curitiba, provided by Curitiba's Institute of Research and Public Planning (IPPUC). The database used in the study was compiled based on an epidemiological survey undertaken in 1998 on a sample of 2126 schoolchildren 12 years old, residing in outlying urban suburbs distributed over 29 micro-areas in the city of Curitiba. The cases selected for this study were those with a history of dental trauma, thereby comprising a subsample of 327 schoolchildren. The spatial location of the schoolchildren's homes enabled the events to be visualized on a cartographic basis. The variables of gender, aetiology of the trauma and areas of substandard living conditions were included in the analysis and construction of thematic maps, thus making possible a descriptive analysis of the spatial distribution of dental trauma in the city. Intra-urban differentials were identified in the prevalence of dental trauma in 12-year-old schoolchildren in Curitiba. A greater concentration of occurrences was observed in the eastern region of the city, especially in areas of substandard living conditions. It was possible to conclude that socio-environmental and geophysical factors are associated with the determination of dental trauma in the city of Curitiba, pointing to the need for the development of public policies especially aimed at areas and populations at greater risk.
