To evaluate the quality-of-life of students in Nova Friburgo, Rio de Janeiro, who suffered traumatic dental injury.
A case-control study was carried out by means of structured questionnaire for traumatic dental injury evaluation, clinical oral examination and application of a quality-of-life questionnaire (CPQ11-14), validated in the Portuguese version. This study consisted of 50 children/adolescents (17 cases of traumatic dental injury and 33 controls). Psychometric properties, like internal consistency (Cronbach's Alpha) and test-re-test reliability (ICC), were evaluated. The independent variables were collected for being of interest to the study (dental trauma) or for acting as potential confounding factors (malocclusion, caries). Descriptive and univariate analyses were performed.
The Cronbach's Alpha was 0.90 for case and 0.77 for controls. ICC was 0.99. When the groups were compared, confounding factors showed no statistical difference (p > 0.05). Among the cases CPQ11-14 mean score was 17.59 (SD = 14.01), median = 17.00, whereas among the controls it was 3.09 (SD = 4.42), median = 1.00 (p < 0.01, Mann-Whitney test). When the groups were compared, there was statistical difference frequencies between CPQ11-14 total scale and sub-scales (p < 0.05). The functional limitation and emotional well-being were the sub-scales most affected. The TDI impact was related to 'delay and difficulty in chewing', 'embarrassed or ashamed' and 'caring about what others were thinking of appearance'.
One can observe a relationship between traumatic dental injury and its impact on quality-of-life. Children and adolescents who suffered traumatic dental injury showed negative experiences and greater functional and emotional impact.
评估巴西里约热内卢新弗里堡市遭受创伤性牙外伤学生的生活质量。
采用创伤性牙外伤评估结构化问卷、临床口腔检查和生活质量问卷（CPQ11-14）进行病例对照研究，该问卷经葡萄牙语验证。该研究包括 50 名儿童/青少年（17 例创伤性牙外伤和 33 名对照）。评估了心理测量学特性，如内部一致性（Cronbach's Alpha）和测试-重测信度（ICC）。收集的自变量与研究相关（牙外伤）或作为潜在混杂因素（错畸形、龋齿）有关。进行了描述性和单变量分析。
病例组的 Cronbach's Alpha 为 0.90，对照组为 0.77。ICC 为 0.99。当比较两组时，混杂因素无统计学差异（p > 0.05）。在病例组中，CPQ11-14 的平均得分为 17.59（SD = 14.01），中位数为 17.00，而在对照组中得分为 3.09（SD = 4.42），中位数为 1.00（p < 0.01，Mann-Whitney 检验）。当比较两组时，CPQ11-14 总分和子量表的频率存在统计学差异（p < 0.05）。功能障碍和情绪健康是受影响最大的子量表。TDI 的影响与“咀嚼延迟和困难”、“尴尬或羞耻”和“关心他人对外观的看法”有关。
可以观察到创伤性牙外伤与其对生活质量的影响之间存在关系。遭受创伤性牙外伤的儿童和青少年经历了负面体验，并且功能和情绪方面受到更大的影响。
