Psychometric properties of the Dutch version of the Orofacial Esthetic Scale (OES‐NL) in dental patients with and without self‐reported tooth wear

Abstract

The aim of this study was to test the psychometric properties of the Dutch version of the Orofacial Esthetic Scale (OES) in dental patients with and without self-reported tooth wear. The English version of the OES was translated into Dutch, following established guidelines for cross-cultural adaptation of health-related quality of life measures. The reliability of the resulting OES-NL was tested in a test-retest study on 343 subjects; its validity was tested with the use of convergent validity on 582 subjects. The test-retest reliability of the OES-NL showed intra-class correlation coefficients (ICC) that ranged from 0·76 to 0·82, which can be qualified as excellent. The Cronbach's alpha revealed that the overall internal consistency of the scale was good (α = 0·89). Convergent validity was confirmed by the association between the OES-NL summary scores and three questions of the Dutch version of the Oral Health Impact Profile (OHIP-NL). The calculated Spearman's rank correlation coefficients ranged from -0·43 to -0·54 and were all significant (P < 0·001). The Dutch version of the Orofacial Esthetic Scale (OES-NL) showed good psychometric properties, making it suitable for the assessment of self-perceived aesthetics in Dutch dental patients with and without self-reported tooth wear.

The tooth wear evaluation system: a modular clinical guideline for the diagnosis and management planning of worn dentitions

“…Questionnaires about oral parafunctions , reflux disease , eating disorders and a dry mouth can provide insight into the possible aetiological factors of the worn dentition. Questionnaires can also be helpful for the assessment of the complaints of patients due to their tooth wear, for example impaired oro‐facial aesthetics or limitation in jaw function capability .…”

Impact of administration mode on Oro‐facial Appearance assessment using the Oro‐facial Esthetic Scale

“…However, this should not be a limitation. Other studies already proved convergent validity with external ratings of Oro‐facial Appearance, known‐groups validity, responsiveness and test‐retest reliability of the OES . We see no reason why this should be related to the method of administration.…”

“…Therefore, the Oro‐facial Esthetic Scale (OES), an 8‐item instrument, was developed to overcome this drawback and to comprehensively assess Oro‐facial Appearance from the patient perspective . The OES is unidimensional, exhibited good psychometric properties and is available in several languages . Furthermore, norm values were provided for the general population …”

Measuring Patient’s Orofacial Estheticsin in Prosthodontics: A Scoping Review of a Current Instrument

“…The OES instead evaluates the overall satisfaction of the patient with his/her esthetic appearance. As the most common instrument used in research, the OES has good psychometric properties and has been adapted cross-culturally to several languages such as; Croatia,Chinese,Albanian,Dutch,Germany,Arabic,and Spanish [25,29,[32][33][34]37,40,41]. Although the instrument developed by Tortopidis et al showed good reliability, there has been no report of its use in other published studies.…”
