Although oral health-related quality of life ( OHRQoL) as measured by the Oral Health Impact Profile ( OHIP) is thought to be multidimensional, the nature of these dimensions is not known. The aim of this report was to explore the dimensionality of the OHIP using the Dimensions of OHRQoL ( DOQ) Project, an international study of general population subjects and prosthodontic patients. Using the project's Learning Sample ( n = 5173), we conducted an exploratory factor analysis on the 46 OHIP items not specifically referring to dentures for 5146 subjects with sufficiently complete data. The first eigenvalue (27·0) of the polychoric correlation matrix was more than ten times larger than the second eigenvalue (2·6), suggesting the presence of a dominant, higher-order general factor. Follow-up analyses with Horn's parallel analysis revealed a viable second-order, four-factor solution. An oblique rotation of this solution revealed four highly correlated factors that we named Oral Function, Oro-facial Pain, Oro-facial Appearance and Psychosocial Impact. These four dimensions and the strong general factor are two viable hypotheses for the factor structure of the OHIP. [ABSTRACT FROM AUTHOR]

Patients' perspective is increasingly re-cognised as an important outcome measure in oral surgery. However, how patients perceive the surgical treatment cannot be assessed currently. This would be an important indicator for process-related quality of care. It was the aim to develop and to validate an instrument for the assessment of patient-based measures of process-related quality of care in oral surgery. The new Burdens in Oral Surgery Questionnaire (Bi OS-Q) was developed in two steps in patients undergoing oral surgery. First, an item pool was created using semi-structured interviews in 90 patients. Second, a preliminary version was applied in 297 consecutively recruited patients to assess redundancy, completion rates, face validity, difficulty and distribution. Psychometric properties of the final version of the questionnaire were evaluated. The Bi OS-Q consists of 16 items and showed satisfactory internal consistency (Cronbach's alpha = 0·84) and excellent test-retest reliability ( ICC = 0·90). The questionnaire's mean score was significantly correlated with dentists' burdens ( r = 0·44) and patients' overall satisfaction ( r = 0·39) indicating sufficient validity. The Bi OS-Q is a reliable and valid instrument for the assessment of patient-based process-related quality of care in oral surgery. [ABSTRACT FROM AUTHOR]

Objectives: We aimed to assess the association between molar incisor hypomineralization (MIH) and the oral health-related quality of life (OHRQoL) in a group of 7- to 14-year-old children in Berlin, Germany. Materials and methods: The cross-sectional study consisted of a consecutive sample of 317 children, aged 7–14 years (49% girls, 51% boys; mean age, 8.71). Data were collected between June 2018 and December 2019. MIH was diagnosed using the criteria of the European Academy of Paediatric Dentistry. OHRQoL was assessed using the German 19-item version of the Child Oral Health Impact Profile (COHIP-G19). Differences in COHIP-19 summary scores between controls without MIH and MIH patients and with regards to MIH severity were tested for statistical significance using t test and analysis of variance (ANOVA), respectively. Results: Data were obtained for 217 untreated MIH patients and 100 controls. OHRQoL of MIH patients was significantly more impaired than of controls indicated by COHIP-19 mean scores (60.9 ± 10.7 vs. 67.9 ± 7.8; p < 0.001). Patients with severe MIH (59.6 ± 11.0) reported significantly worse OHRQoL than patients with mild MIH (63.6 ± 9.1; p = 0.013). Conclusions: MIH has a significant negative impact on the children's OHRQoL. Patients with severe MIH experience a greater negative impact on OHRQoL than those diagnosed with mild MIH. Clinical significance: MIH is one of the major dental problems of our time; pediatric dentists should be aware of its impact on the OHRQoL of the patient. [ABSTRACT FROM AUTHOR]

Cultural background influences how migrants and ethnic minority populations view and assess health. Poor oral health literacy (OHL) may be a hindrance in achieving good oral health. This systematic review summarizes the current quantitative evidence regarding OHL of migrants and ethnic minority populations. The PubMed database was searched for original quantitative studies that explore OHL as a holistic multidimensional construct or at least one of its subdimensions in migrants and ethnic minority populations. 34 publications were selected. Only 2 studies specifically addressed OHL in migrant populations. Generally, participants without migration background had higher OHL than migrant and ethnic minority populations. The latter showed lower dental service utilization, negative oral health beliefs, negative oral health behavior, and low levels of oral health knowledge. Due to its potential influence on OHL, oral health promoting behavior, attitudes, capabilities, and beliefs as well as the cultural and ethnic background of persons should be considered in medical education and oral health prevention programs.

How dental patients are affected by oral conditions can be described with the concept of oral health-related quality of life ( OHRQoL). This concept intends to make the patient experience measurable. OHRQoL is multidimensional, and Oral Function, Oro-facial Pain, Oro-facial Appearance and Psychosocial Impact were suggested as its four dimensions and consequently four scores are needed for comprehensive OHRQoL assessment. When only the presence of dimensional impact is measured, a pattern of affected OHRQoL dimensions would describe in a simple way how oral conditions influence the individual. By determining which patterns of impact on OHRQoL dimensions exist in prosthodontic patients and general population subjects, we aimed to identify in which combinations oral conditions' functional, painful, aesthetical and psychosocial impact occurs. Data came from the Dimensions of OHRQoL Project with Oral Health Impact Profile ( OHIP)-49 data from 6349 general population subjects and 2999 prosthodontic patients in the Learning Sample ( N = 5173) and the Validation Sample ( N = 5022). We hypothesised that all 16 patterns of OHRQoL dimensions should occur in these individuals who suffered mainly from tooth loss, its causes and consequences. A dimension was considered impaired when at least one item in the dimension was affected frequently. The 16 possible patterns of impaired OHRQoL dimensions were found in patients and general population subjects in both Learning and Validation Samples. In a four-dimensional OHRQoL model consisting Oral Function, Oro-facial Pain, Oro-facial Appearance and Psychosocial Impact, oral conditions' impact can occur in any combination of the OHRQoL dimensions.

Previous exploratory analyses suggest that the Oral Health Impact Profile ( OHIP) consists of four correlated dimensions and that individual differences in OHIP total scores reflect an underlying higher-order factor. The aim of this report is to corroborate these findings in the Dimensions of Oral Health-Related Quality of Life ( DOQ) Project, an international study of general population subjects and prosthodontic patients. Using the project's Validation Sample ( n = 5022), we conducted confirmatory factor analyses in a sample of 4993 subjects with sufficiently complete data. In particular, we compared the psychometric performance of three models: a unidimensional model, a four-factor model and a bifactor model that included one general factor and four group factors. Using model-fit criteria and factor interpretability as guides, the four-factor model was deemed best in terms of strong item loadings, model fit ( RMSEA = 0·05, CFI = 0·99) and interpretability. These results corroborate our previous findings that four highly correlated factors - which we have named Oral Function, Oro-facial Pain, Oro-facial Appearance and Psychosocial Impact - can be reliably extracted from the OHIP item pool. However, the good fit of the unidimensional model and the high interfactor correlations in the four-factor solution suggest that OHRQoL can also be sufficiently described with one score.
