ABSTRACT To develop and evaluate shortened forms of the Oral Health Impact Profile (OHIP) for discriminating dental aesthetics problems and evaluating dental aesthetic outcomes.
Eighty-seven subjects self-completed the 49-item OHIP at baseline and 63 at follow up (8 weeks later), with the intervention of applying an array of tooth-whitening products. Expert-based approach and regression analysis (on baseline data) were undertaken to derive two subset questionnaires (OHIP-conceptual and OHIP-regression). Their discriminatory ability for dental aesthetics and their responsiveness to tooth whitening were compared with the original OHIP-49, Slade's OHIP-14 and a Chinese short-form version of OHIP.
The measures developed were strongly associated with self-rating of dental aesthetics (P < 0.001) unlike OHIP-49 (P = 0.03) or other OHIP short forms (P > 0.05). The measures were also reliable (Cronbach's alpha 0.86) and comparable with the other OHIP forms. In terms of effect size, OHIP-conceptual was more effective in measuring changes than the one based on the regression analysis, the original OHIP-49, OHIP-14 and the Chinese version of the short-form OHIP. It also exhibited a less susceptibility to floor effects than other OHIP forms.
A modified short form of the OHIP derived (OHIP-conceptual) was the most favorable in discriminating dental aesthetics, was reliable and most sensitive to the dental aesthetics intervention - tooth whitening.

    ABSTRACT: The aim of this study was to evaluate the reliability and the validity of the Chinese version of the Dentine Hypersensitivity Experience Questionnaire (DHEQ). After translation and cross-cultural adaptation following international guidelines, 110 patients with dentine hypersensitivity were recruited to complete the questionnaire. The reliability of the Chinese version of the DHEQ was evaluated using internal consistency and test-retest methods. Construct validity was determined based on factor analysis, discriminative validity (by comparing the subscale scores difference in the degree of sensitivity being investigated), and convergent validity (by analyzing the correlation between DHEQ subscale scores and the global rating of oral health question). Cronbach's alpha value (internal reliability) for the total DHEQ score was 0.95 and the intraclass correlation coefficient (ICC) value (test-retest reliability) was 0.85. Construct validity was determined by factor analysis, extracting eight factors, accounting for 74% of the variance. All items had factor loadings of >0.40. In addition, the Chinese version of the DHEQ was found to be valid for distinguishing patients with varying degrees of dentine hypersensitivity. In terms of convergent validity, the impact scale was significantly highly correlated to the global oral health rating. The results suggest that the Chinese version of the DHEQ has satisfactory psychometric properties and is applicable for patients with dentine hypersensitivity in China.

    ABSTRACT: OBJECTIVES: To determine the impact of hypodontia on the quality of life of adolescent and young adult patients, and, to assess the impact of restoring tooth spaces with resin bonded bridgework on quality of life of patients with hypodontia METHODS: In a prospective study, 82 patients with a confirmed diagnosis of hypodontia participated. The primary outcome was oral health related quality of life (OHRQoL) and this was measured using the OHIP-49 prior to treatment. The pre-treatment sample was then divided into two groups: the test group (n=40 patients) who had completed orthodontic treatment and had tooth spaces restored with resin bonded bridgework, and, a control group (n=42 patients) who were still in the process of orthodontic treatment. All patients completed a follow-up OHIP-49, and between and within group comparisons made RESULTS: The pre-treatment sample included 43 females and 39 males, age ranged from 16 -34 years (median age 19). Forty three patients had more than 4 congenitally missing teeth and thirty nine had ≤ 4 congenitally missing teeth. There were no differences between the groups prior to treatment. For the test group, there was a significant improvement in median OHIP summary scores (p<0.001) after treatment. OHIP scores deteriorated to a significant degree for control subjects (p=0.002). The effect sizes for the pre-post treatment change in both groups were moderate to large CONCLUSIONS: Hypodontia has a significant impact on oral health related quality of life. Provision of resin bonded bridges has a positive impact on oral health related quality of life of patients with hypodontia.

    ABSTRACT: PURPOSE: The objective was to determine the responsiveness properties of the Oral Health Impact Profile (OHIP) short-forms and 36-item Short-Form (SF-36) in complete denture treatment, and further to evaluate the association between patients' satisfaction and improvements in oral and general health-related quality of life (OHRQoL and HRQoL) after fitting of new, complete dentures. METHODS: Study data were obtained from the 'Dentures for the Elders through Public Funding' study conducted in Kaohsiung County. A total of 224 subjects received denture treatments with 6-month follow-up and pre-/post-treatment interviews by questionnaire. The OHIP and SF-36 were used to measure OHRQoL and HRQoL. In addition, specific questions investigating seven aspects of patients' satisfaction were used to measure the patients' perceptions of complete denture success. The responsiveness of all outcome measures and their dimensions were assessed by effect size (ES). Multivariable analysis was used to examine the association between patients' satisfaction and OHIP/SF-36 while adjusting for demographic characteristics. RESULTS: There were improvements with regard to the 'physical pain' (ES = 0.19) and 'psychological discomfort' (ES = 0.42) dimensions of the Taiwanese short-form OHIP (OHIP-14T) after new complete denture treatment, but only improvement in the 'general health' (ES = 0.17) dimension in the SF-36 measure. Patients satisfied with 'comfort' and 'ease of cleaning' of their new dentures were significantly associated with the improvement of the OHIP-49 and OHIP-14T. CONCLUSIONS: This study suggests that denture treatments are associated with improvements of OHRQoL, but not in HRQoL. Furthermore, patients' satisfaction was significantly associated with responsiveness of OHRQoL but less significantly associated with responsiveness of HRQoL.
