Although clinical dental status has weak correlations with subjective impacts, some of them are significant. Those variables which had significant correlations could be used as a starting point to understand clinical and social characteristics of people who experience dental problems. This is indeed the basis for the current research. The study compares psychosocial impacts on the quality of people's life with their respective oral status. To that end, a socio-dental indicator, the 'Dental Impact of Daily Living' (DIDL), involving five dimensions, together with a scale which assesses dimension impacts, was developed. The resulting instrument was validated and the reliability tested. The instrument generates a total final score, in addition to scores for each dimension. The method was tested in Brazil on a sample of 662 people, aged from 35 to 44 years, of two social classes, both sexes, and with three different levels of dental caries status or with a full upper denture. To test whether DIDL discriminated between groups with different levels of subjective impact, we analyzed how oral status, social class, and gender varied according to impacts. Different levels of oral status had different impacts on people's daily life. On the basis of the results, it is reasonable to suggest that oral status and social and psychological dimensions should be considered simultaneously when in assessment of people's dental needs.
尽管临床牙齿状况与主观影响之间的相关性较弱，但其中一些相关性是显著的。那些具有显著相关性的变量可以作为理解有牙齿问题的人的临床和社会特征的起点。这确实是当前研究的基础。该研究将心理社会因素对人们生活质量的影响与其各自的口腔状况进行了比较。为此，开发了一种社会牙科指标，即“日常生活中的牙齿影响”（DIDL），它涉及五个维度，以及一个评估各维度影响的量表。对所得工具进行了验证并测试了其可靠性。该工具除了能得出每个维度的分数外，还能得出一个最终总分。该方法在巴西对662名年龄在35至44岁之间、来自两个社会阶层、男女皆有、具有三种不同龋齿状况水平或佩戴全口上假牙的人群样本进行了测试。为了测试DIDL是否能区分具有不同主观影响水平的群体，我们分析了口腔状况、社会阶层和性别如何根据影响而变化。不同水平的口腔状况对人们的日常生活有不同的影响。基于这些结果，合理的建议是，在评估人们的牙齿需求时，应同时考虑口腔状况以及社会和心理维度。
