The purposes of the present study were to (1) evaluate the esthetic dental treatment need by means of two special questionnaires, (2) determine the reliability and the construct validity of the measurement scales derived from these questionnaires, and (3) investigate the relationship between Greek subjects' perception and a professional examiner's assessment regarding the esthetic treatment need.
Participants in this survey consisted of 132 subjects (48 males with mean age 39.0 +/- 14.5 years old, 84 females with mean age 41.7 +/- 14.5 years old) with natural teeth and fixed restorations. Subjects were asked to complete a special self-evaluation questionnaire consisting of 12 items. During the next stage, all participants were clinically examined by an experienced examiner and the data collected were used to fill out a second special professional assessment questionnaire consisting of 20 items. The forms structure used were in accordance with well-established indices used in orthodontics for assessing esthetic treatment need.
The reliability of the multiple correspondence analysis (MCA) analysis-derived scales was very satisfactory (Cronbach's a coefficient: a =0.82) for the total scale of the self-evaluation measurement. For the professional assessment scale, the reliability of the total scale was almost perfect (a=0.92). The MCA revealed one reliable factorial construct for the self-evaluation measurement scale and two reliable constructs for the professional measurement scale. Pearson's correlation coefficient indicated a very low agreement between self-evaluation and professional measurement scales.
The findings of this survey suggest that there was a relative disagreement between subjects' perception and professional assessment regarding the need for esthetic dental treatment. CLINICAL SIGNIFICANCE In the present survey, the agreement between subjects' perception and clinical assessment of esthetic dental treatment need was found to be very low, which highlighted the discrepancies between patients' and dentists' perceptions of esthetic needs.
本研究的目的是：（1）通过两份特殊问卷评估牙齿美容治疗需求；（2）确定从这些问卷得出的测量量表的信度和结构效度；（3）研究希腊受试者对美容治疗需求的认知与专业检查者评估之间的关系。
本调查的参与者包括132名有天然牙和固定修复体的受试者（48名男性，平均年龄39.0±14.5岁；84名女性，平均年龄41.7±14.5岁）。受试者被要求完成一份由12项内容组成的特殊自我评估问卷。在下一阶段，所有参与者由一名经验丰富的检查者进行临床检查，收集的数据用于填写一份由20项内容组成的第二份特殊专业评估问卷。所使用的表格结构符合正畸学中用于评估美容治疗需求的既定指标。
多重对应分析（MCA）得出的量表在自我评估测量总量表方面的信度非常令人满意（Cronbach's α系数：α=0.82）。对于专业评估量表，总量表的信度几乎完美（α=0.92）。MCA显示自我评估测量量表有一个可靠的因子结构，专业测量量表有两个可靠的结构。Pearson相关系数表明自我评估量表和专业测量量表之间的一致性非常低。
本次调查结果表明，受试者对牙齿美容治疗需求的认知与专业评估之间存在相对差异。临床意义 在本次调查中，发现受试者对牙齿美容治疗需求的认知与临床评估之间的一致性非常低，这突出了患者和牙医对美容需求认知之间的差异。
