Objective: To assess dental treatment under dental general anesthesia (DGA) among Chinese preschool children by investigating changes in their oral health-related quality of life (OHRQoL), the incidence of postoperative complications, and parental satisfaction., Method: A single-center prospective cohort study was conducted. A total of 190 children who received treatment for early childhood caries (ECC) under DGA were included. The primary outcome was a change in the children's OHRQoL at 1 month after the operation compared to that at baseline, which was measured by the Early Childhood Oral Health Impact Scale (ECOHIS). The secondary outcomes were the incidence of complications within 1 day after treatment and parental satisfaction with the DGA treatment., Results: In total, 180 participants were successfully reevaluated after the operation, yielding a 94.7% follow-up response rate. The total ECOHIS score decreased by 76.3% (P < 0.01) after treatment, demonstrating a large effect. Approximately 74.4% of the children complained of at least one complication, including sleepiness (43.3%), emergence agitation (38.9%), nausea/vomiting (13.9%), dizziness (10.6%), and fever (3.3%), on the first day. Approximately 85.5% of the parents were satisfied with the DGA treatment., Conclusion: DGA treatment has a positive effect on Chinese preschool children's OHRQoL and is evaluated highly by their parents., Clinical Relevance: Dental treatment under general anesthesia improved the OHRQoL of Chinese preschool children.

Objectives: The aim of this study was to evaluate the reliability and validity of the Chinese version of the Oral Health Impact Profile for edentulous subjects (OHIP-EDENT-C)., Methods: After translation and cross-cultural adaptation following international guidelines, 162 complete denture wearers were recruited to complete the questionnaire. The reliability of the OHIP-EDENT-C was evaluated using internal consistency and test-retest methods. The validity of the OHIP-EDENT-C was analyzed by construct validity and convergent validity. Construct validity was determined based on factor analysis and convergent validity by analyzing the correlation between OHIP-EDENT-C subscale scores and the global question., Results: Cronbach's alpha value (internal reliability) for the total OHIP-EDENT-C score was 0.972, and the intraclass correlation coefficient value (test-retest reliability) was 0.763 (similar to the original OHIP-EDENT). Construct validity was determined by factor analysis, extracting five factors, accounting for 74.31 % of the variance. All items had factor loadings above 0.40. In terms of convergent validity, the OHIP-EDENT-C subscale was significantly highly correlated to the global question., Conclusion: The results suggest that the OHIP-EDENT-C is a reliable and valid measure to evaluate OHRQoL for edentulous subjects in China.

Objectives: The aim of this study was to validate the Chinese version of the Summated Xerostomia Inventory (SXI)., Methods: The English SXI was translated into Chinese, cross-cultural adaptation and pilot tested. The final Chinese version of SXI was tested in a consecutive sample of 212 patients with xerostomia. The reliability of the Chinese version of SXI was determined through internal consistency and test-retest methods. The construct validity of SXI was analysed by content validity, construct validity, and convergent validity., Results: Cronbach's alpha value for the SXI score was 0.798, and the test-retest intraclass correlation coefficient value for the SXI score was 0.837. Construct validity was proved by the presence of one-factor structure that accounted for 57.68 % of the variance and fitted well into the model. The correlation between the total score of the SXI and the global oral health question was 0.75, indicating very good correlation (P < 0.01)., Conclusion: This study provided preliminary evidence concerning validity and reliability of the Chinese version of the SXI. The results provide initial evidence that the SXI may be a useful tool for the mainland Chinese xerostomia patients for both clinical and epidemiologic researches.

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., (© 2012 Eur J Oral Sci.)
