RESUMO
INTRODUCTION: Dentofacial deformities impose a negative impact on quality of life (QOL). Orthognathic surgery is the main pillar of treatment for these conditions and has proven its impact on the improvement of the functional and psychosocial aspects of QOL. The Orthognathic Quality of Life Questionnaire (OQLQ), developed by Cunningham and colleagues, is a well-established instrument for assessing QOL in patients with dentofacial deformities. OBJECTIVE: The aim of this study was to perform a translation, transcultural adaptation, and validation of a Hebrew version of the OQLQ. METHODS: Transcultural adaptation was done following guidelines proposed by Beaton and colleagues resulting in a pilot study conducted on 20 patients undergoing orthognathic surgery. Internal consistency, reliability, and sensitivity were evaluated by means of Cronbach alpha, intraclass correlation coefficient (test-retest), and Wilcoxon test, respectively. Validity was assessed by comparing the OQLQ with the Hebrew version of the Oral Health Impact Scale-14 (Oral Health Impact Profile Scale-14) using the Spearman correlation test. RESULTS: Internal consistency showed a good correlation between domains and excellent test-retest reliability. Sensitivity to change was statistically significant in all but 3 questions. The Hebrew version of the OQLQ exhibited a strong correlation with Oral Health Impact Profile Scale-14 in total score and moderate to high correlations among domains. CONCLUSION: The Hebrew version of the OQLQ is a valid and reliable and specific instrument to measure QOL for Hebrew-speaking patients undergoing orthognathic surgery.
RESUMO
BACKGROUND: There is a lack of evidence on caries prevalence among 18 years old Israeli young adults with only a scarce evidence regarding this index age group. In the last few years dental care policy in Israel underwent substantial changes and a major reform in dental services was led by the Israeli Ministry of Health, including coverage of dental care for children by the state. In addition, a cessation of community water fluoridation was in a debate. The objective of the current study was to describe prevalence of caries among 18 years old Israeli young adults and to evaluate possible associations with personal and demographic variables. METHODS: The study was a cross sectional clustered survey. Participants were recruited to the study at their first day of military service. Participants completed a questionnaire for personal and demographic data, including: age, country of birth, education, and current smoking status. Then participants underwent clinical evaluation included DMFT and caries free rates. No radiographic evaluation was included in the current study. Univariate and multivariate statistical analysis were performed. RESULTS: A total of 702 participants were included in the study, 58.4% were males. Their mean age was 19.03 ± 0.65 years, 91.3% of the participants were born in Israel. Mean DMFT was 1.95 ± 2.67, and 46.7% (n = 328) were caries free. Higher DMFT score was significantly associated with participant's parents' education, country of birth, and smoking status. Lower caries free rates were significantly associated with participant's parents' education, and smoking status. After linear regression for total DMFT, all variables were significant predictors to higher DMFT, except father's education, while logistic regression for caries free, only mother's education was found to be a significant predictor. CONCLUSIONS: The current study presents encouraging low DMFT levels. Participants in this study were not included in the dental care services reform, and did enjoy the benefits of water fluoridation, enabling the results to play an important baseline data for future reference. Additionally, results should be considered when planning intervention programs for at risk groups. TRIAL REGISTRATION: This study was registered in ClinicalTrials.gov (Identifier No. NCT02958891 , November 8th, 2016) and was approved by the IDF Institutional Review Board (#1524-2015).
