The aim of the study was to evaluate the responsiveness of the Prosthetic Esthetic Index (PEI) in a population who received prosthetic replacements.
Fifty-seven patients who received prosthetic replacement of at least one tooth by means of fixed or removable prosthesis were professionally esthetically evaluated using the PEI and the Dental Aesthetic Index (DAI) before and after treatment. The participants further evaluated their oral esthetics using the Oral Health Impact Profile Aesthetic (OHIP-Aes) and Orofacial Esthetic Index (OES). Responsiveness was determined by calculating effect size (ES) and standardized response mean (SRM) of the change in PEI score, testing the change in PEI score in different subgroups, and correlating the change in PEI score with the change in OHIP-Aes and OES scores. The change in PEI score was compared to the change in DAI score.
The ES and SRM were large for the change in PEI score. Patients having anterior teeth replaced had a larger improvement in PEI score compared to participants not having anterior teeth replaced. The change in PEI score was moderately but significantly correlated to the change in OHIP-Aes and OES scores. The PEI was more consistent in responsiveness than the DAI.
The PEI shows sufficient responsiveness for use in longitudinal studies and for use as a follow-up measure in clinical practice.
The PEI can in a standardized manner monitor and document esthetic improvements and problems as seen by the dentist in clinical practice.
本研究旨在评估义齿美学指数（PEI）在接受义齿修复人群中的反应性。
57例接受了至少一颗牙齿固定或可摘义齿修复的患者在治疗前后使用PEI和牙科美学指数（DAI）进行了专业美学评估。参与者还使用口腔健康影响量表美学版（OHIP-Aes）和口面部美学指数（OES）对自身口腔美学进行了评估。通过计算PEI评分变化的效应量（ES）和标准化反应均值（SRM）、测试不同亚组中PEI评分的变化以及将PEI评分变化与OHIP-Aes和OES评分变化进行相关性分析来确定反应性。将PEI评分变化与DAI评分变化进行比较。
PEI评分变化的ES和SRM较大。与未更换前牙的参与者相比，更换了前牙的患者PEI评分改善更大。PEI评分变化与OHIP-Aes和OES评分变化呈中度但显著的相关性。PEI在反应性方面比DAI更具一致性。
PEI在纵向研究以及临床实践中作为随访指标使用时显示出足够的反应性。
PEI能够以标准化方式监测和记录临床实践中牙医所观察到的美学改善情况及问题。
