Abstract

PURPOSE

The purpose of this study was to determine if vital tooth whitening affects oral health-related quality of life (OHRQOL) in adults age 50 years and older, and if tooth whitening causes increased participation in social activities.

METHODS

Using a 2 group, single blind, randomized, pre-test, multiple post-test design, 62 participants were enrolled. The experimental group used a whitening product twice daily for 3 weeks. The control group used no whitening products. The Oral Health Impact Profile (OHIP) served as the pre- and post-test measure. The OHIP measures OHRQOL on 7 subscales: functional factors, psychological disabilities, psychological discomforts, physical disabilities, social disabilities, handicaps and physical pain. Additional questions measured the subjects' social activities at baseline, 3 weeks and 3 months. Data from 53 participants, who completed the study, were analyzed using paired t-tests and ANOVA at p=0.05.

RESULTS

Statistical significance was observed for the OHIP physical pain subscale (p=0.0029) and the handicap subscale (p=0.05). Pre- to post-test means of the physical pain subscale increased in the experimental group (4.84 to 7.10), suggesting a lower OHRQOL, most likely related to tooth sensitivity experienced by the experimental group. Means from pre- to post-test of the handicap subscale (1.96 to 1.19) reveal that the experimental group reported an improved OHRQOL and felt they were more willing to work. Repeated measures ANOVA and Tukey's post-hoc tests revealed that the experimental group reported significantly less (p=0.04) social activities at the 3 month post-test (3.92 to 3.45). No statistically significant between-group differences were observed in the overall OHIP score for functional factors, psychological disabilities, psychological discomforts, physical disabilities and social disabilities.

CONCLUSION

Results indicate that vital tooth whitening does not improve overall OHRQOL in older adults.

摘要

目的

本研究旨在确定成人牙齿美白是否会影响50岁及以上成年人的口腔健康相关生活质量（OHRQOL），以及牙齿美白是否会导致社交活动参与度增加。

方法

采用两组、单盲、随机、预测试、多次后测试设计，招募了62名参与者。实验组每天使用美白产品两次，持续3周。对照组不使用美白产品。口腔健康影响量表（OHIP）用作预测试和后测试指标。OHIP在7个分量表上测量OHRQOL：功能因素、心理残疾、心理不适、身体残疾、社交残疾、障碍和身体疼痛。其他问题测量了受试者在基线、3周和3个月时的社交活动。对53名完成研究的参与者的数据进行配对t检验和方差分析，显著性水平为p = 0.05。

结果

在OHIP身体疼痛分量表（p = 0.0029）和障碍分量表（p = 0.05）上观察到统计学显著性。实验组身体疼痛分量表的测试前至测试后均值增加（4.84至7.10），表明OHRQOL较低，很可能与实验组经历的牙齿敏感有关。障碍分量表测试前至测试后的均值（1.96至1.19）表明，实验组报告OHRQOL有所改善，并且感觉他们更愿意工作。重复测量方差分析和Tukey事后检验表明，实验组在测试后3个月报告的社交活动显著减少（p = 0.04）（3.92至3.45）。在功能因素、心理残疾、心理不适、身体残疾和社交残疾的总体OHIP评分中，未观察到组间统计学显著差异。
