BACKGROUND/AIM: Knowledge about the spatial density of the domiciles of dental trauma victims can assist in the identification of the most vulnerable areas and contribute to the planning of prevention, promotion, control, and treatment actions, focusing on the most affected areas. The aim of this study was to analyze the spatial density of domiciles of 14-year-old adolescent victims of dental trauma, in the city of Diamantina, Brazil, after a two-year follow-up period.
This longitudinal study was carried out with 584 adolescents between 2013 and 2015. Dental trauma, overjet, and lip protection were assessed by two trained and calibrated examiners (K > 0.70). Information about binge drinking was collected among the adolescents through the Alcohol Use Disorders Identification Test and sociodemographic indicators were obtained through a questionnaire answered by the caregivers of the adolescents. Spatial analyses were performed to evaluate the spatial density of adolescents with dental trauma and the independent variables of interest according to the domicile using Ripley's K function and the Kernel Map.
Ripley's K function revealed spatial aggregation of the domiciles of adolescent victims of dental trauma in relation to males, binge drinking and overjet, with a confidence interval of 95%. The higher density of domiciles with adolescents with two or more traumatized teeth was found in the north-east region of the city. Boys were the most affected, their homes were located in the north, north-west, and south-east regions at baseline and follow-up. The largest density of domiciles of adolescents with overjet greater than 5 mm and inadequate lip protection was in the north-east region. Similar spatial distribution was identified for binge drinking for both years.
The majority of adolescents with dental trauma lived in the north-east and south-east regions, characterized by high population density and greater social vulnerability.
背景/目的：了解牙外伤受害者住所的空间密度有助于确定最脆弱的区域，并有助于规划预防、促进、控制和治疗措施，重点关注受影响最严重的区域。本研究旨在分析巴西 Diamantina 市 14 岁牙外伤青少年受害者在两年随访期后的住所空间密度。
这项纵向研究于 2013 年至 2015 年期间对 584 名青少年进行了研究。两名经过培训和校准的检查者评估了牙外伤、覆𬌗和唇保护情况（K>0.70）。通过酒精使用障碍识别测试收集了青少年的狂欢饮酒信息，并通过青少年护理人员回答的问卷获得了社会人口学指标。使用 Ripley 的 K 函数和核图对空间分析进行了评估，以评估牙外伤青少年及其根据住所的相关变量的空间密度。
Ripley 的 K 函数显示，与男性、狂欢饮酒和覆𬌗相比，牙外伤青少年住所存在空间聚集，置信区间为 95%。发现有两颗或更多牙齿受伤的青少年住所密度较高的地区位于城市的东北部。男孩受影响最大，他们的家位于城市的北部、西北部和东南部，无论是基线还是随访时都是如此。覆𬌗大于 5 毫米且唇保护不足的青少年住所密度最大的地区位于东北部。对于狂欢饮酒，在这两年中都发现了类似的空间分布。
大多数牙外伤青少年居住在东北部和东南部，这些地区人口密度高，社会脆弱性较大。
