Abstract：
BACKGROUND: Assessment of taste and somatosensory perception in clinical practice lacks fast tests that are validated and reliable. Recently, a 12-item identification test for taste and oral trigeminal perception, and its shorter version, the Seven-iTT, was developed. The objectives of this study were to evaluate its test-retest reliability and establish normative data.
METHODS: Two-hundred participants (120 women, 80 men) with a good sense of taste performed a whole-mouth identification test using 12 filter-paper strips impregnated with low and high concentrations of sweet, sour, salty, bitter, astringency, and spiciness. Fifty of them repeated the task, with a median interval of 122 days from the first visit. Test-retest reliability was determined using Spearman correlation and the Bland-Altman plot method.
RESULTS: There was a significant correlation in identification score between the first and the second session for both versions of the test (r ≥ 0.28; p ≤ 0.048). The Bland-Altman plot reflected a good congruence between the results of the two sessions. Additionally, frequencies of correct identification were consistent between sessions, with women outperforming men (p = 0.005). Hypogeusia was established at Seven-iTT score of 3 of less.
METHODS: The identification test combines taste and somatosensory perception, thus creating a more detailed diagnosis tool. Scores were correlated with self-rated taste perception.
CONCLUSIONS: The present results confirmed the applicability of Seven-iTT for a reliable, fast evaluation of taste and somatosensory perception in the general population, that can be extended to clinical practice.

摘要：
背景：临床实践中对味觉和体感知觉的评估缺乏经过验证和可靠的快速测试。最近,味道和口腔三叉神经感知的12项识别测试，和它的较短版本，Seven-ITT,已开发。本研究的目的是评估其重测可靠性并建立规范数据。
方法：两百名参与者（120名女性，80名男性）具有良好的味觉，使用12条浸渍有低浓度和高浓度甜味的滤纸条进行了全口识别测试，酸,咸,苦涩,收敛性,和辣味。他们中的50人重复了这项任务，从第一次访问开始的中位数间隔为122天。使用Spearman相关性和Bland-Altman图法确定重测可靠性。
结果：对于两个版本的测试，第一和第二会话之间的识别得分存在显着相关性（r≥0.28；p≤0.048）。Bland-Altman的情节反映了两次会议结果之间的良好一致性。此外,正确识别的频率在会话之间是一致的，女性表现优于男性(p=0.005)。在7-iTT得分为3分以下时，建立了缺省感。
方法：识别测试结合了味觉和体感知觉，从而创建一个更详细的诊断工具。得分与自我评估的味觉感知相关。
结论：本结果证实了Seven-iTT对于可靠的，快速评估普通人群的味觉和体感知觉，这可以扩展到临床实践。
