This study aimed to correlate the general well-being of patients and their judgment about their dental appearance.
Based on internationally accepted guidelines regarding dental esthetics, a questionnaire was developed to measure subjective assessments of dental appearance. Fourteen items defined an esthetic sum score (0 = satisfied; 56 = dissatisfied). Further, general well-being was evaluated with a long-established and highly reliable test. Eighty participants were included (47 women, 33 men). Participants were.drawn from 4 different groups (n = 20): natural dentition (group N), fixed partial dentures (group F), removable partial dentures (group R), and patients who had an esthetic problem with their teeth (group P).
Seventy-five participants showed a normal well-being. Five participants showed a depressive state and formed a new group (group D). The medians of the sum scores (25th, 75th percentile) were: group N: 12 (10, 14); group F: 14 (8, 29); group R: 14 (9, 27); group P: 23 (18, 35); group D: 30 (26, 35). Significant differences were found between groups N and P, as well as between group D and groups N, F, and R.
Because of the significant difference between groups N and P, basis validation of the sum score was achieved. Further, self-assessments of dental appearance appeared to be more negative for participants with a depressive state compared with the other groups. In clinical studies, selection bias can be prevented by using a test that measures well-being to verify if a study sample includes a normal number of depressive subjects and therefore represents the general population.
本研究旨在关联患者的总体幸福感与其对自身牙齿外观的判断。
基于国际公认的牙齿美学指南，编制了一份问卷以测量对牙齿外观的主观评估。14个项目定义了一个美学总分（0分 = 满意；56分 = 不满意）。此外，采用一项长期确立且高度可靠的测试评估总体幸福感。纳入80名参与者（47名女性，33名男性）。参与者来自4个不同组（每组n = 20）：天然牙列组（N组）、固定局部义齿组（F组）、可摘局部义齿组（R组）以及牙齿存在美学问题的患者组（P组）。
75名参与者表现出正常的幸福感。5名参与者表现出抑郁状态，组成一个新组（D组）。总分的中位数（第25、75百分位数）分别为：N组：12（10，14）；F组：14（8，29）；R组：14（9，27）；P组：23（18，35）；D组：30（26，35）。在N组和P组之间以及D组与N组、F组和R组之间发现了显著差异。
由于N组和P组之间存在显著差异，实现了总分的基本验证。此外，与其他组相比，抑郁状态的参与者对牙齿外观的自我评估似乎更负面。在临床研究中，通过使用测量幸福感的测试来验证研究样本中抑郁受试者的数量是否正常，从而代表一般人群，可以防止选择偏倚。
