Impact of orthodontic treatment with aligners on the oral health-related quality of life of patients with trisomy 21.

To assess the impact of treatment with orthodontic aligners (OA) on oral health-related quality of life (OHRQoL) in patients with trisomy 21 (T21) compared to non-syndromic patients. The sample consisted of 30 patients, both sexes, aged between 11 and 35 years, divided into two groups: T21 (n=10, patients with T21, treated prospectively) and CONTROL (n=20, control group, non-syndromic patients, from the Orthodontic Laboratory of UNOPAR). In both groups, patients were treated with Invisalign orthodontic aligners (Align Technology), following the same treatment parameters. Participants, assisted by their caregivers, when necessary, answered Oral Health Impact Profile (OHIP-14) instrument and the patient's guardians answered the Oral Health Scale for People with Down's syndrome (OHDS) instrument, before (T0) and after 30 (T1), 180 (T2), and 365 (T3) days from the start of treatment. Friedman tests with Bonferroni correction and Mann-Whitney tests were used (p<.05). For the OHDS instrument, it was observed that for the eating and communication domains and an overall score, the treatment with OA positively impacted the lives of T21 patients (p<.05). Regarding the OHIP-14 instrument, the intragroup evaluation showed that in the CONTROL group, there was no significant difference between the evaluated times; while for the T21 group, there was a significant positive impact (p<.05). The results showed that the treatment with aligners positively impacted the OHRQoL of T21 patients, and these results were perceived by caregivers, mainly in relation to issues related to eating and communication.

Parental Attitudes towards Child Oral Health and Their Structural Analysis.

The relationship between parental attitudes towards health and child development has been a topic of interest for many years; however, research results in this field are still inconsistent. This study aimed to develop a structural equation model of the Parental Attitudes toward Child Oral Health (PACOH) scale, using this model to analyse the relationship between parental attitudes with demographic variables and the oral health-related behaviour of parents and children. A total of 302 parents (87% mothers) answered questions regarding their own and their children's, aged 4-7 years, oral health-related actions and completed the 38-item PACOH scale. The structural equation model indicated that parental attitudes captured by the PACOH scale can be fitted to a second-order factorial model, even with the scale shortened to 21 items. The model demonstrated good fit characteristics (CFI = 0.925; IFI = 0.927; GFI = 0.915; RMSEA = 0.049), making it a reliable tool for examining the structure of parental attitudes. This model was employed in the multi-group analysis, revealing the close relationship between positive parents' attitudes towards their child's oral health and oral health-promoting behaviour both in parents and children, such as regular tooth brushing (p < 0.001), visiting the dentist (p = 0.027), and parents helping their child brush his/her teeth (p < 0.001). In light of these findings, it was concluded that Parental Attitudes towards Child Oral Health should be considered an essential factor influencing the development of oral health-promoting behaviour in children.

Quality of life in children and adolescents with blood coagulation disorders and hemoglobinopathies.

The aim of this study was to evaluate the impact of oral conditions and health-related quality of life (HRQoL) on oral health-related quality of life (OHRQoL) in children and adolescents with blood coagulation disorders and hemoglobinopathies (BCDH). The study was cross-sectional and included 61 individuals aged 2 to 18 years with BCDH. Exams for dental caries (dmft/DMFT index), oral hygiene (simplified oral hygiene index - OHI-S), and gingival health (modified gingival index - MGI) were performed. The pediatric quality of life inventory™ (PedsQL™) generic core scale and oral health scale were used to measure HRQoL and OHRQoL. Spearman's correlation coefficient (ρ) and the Mann-Whitney test (α = 0.05) were conducted to assess the relationship between covariates and the PedsQL™ oral health scale. The mean PedsQL™ oral health scale score was 76.66 (SD = 21.36). Worse OHRQoL was correlated with poor oral hygiene (ρ = -0.383; p: 0.004), poor gingival health (ρ = -0.327; p = 0.014), and better HRQoL (ρ = 0.488; p < 0.001). Greater untreated dental caries experience was associated with worse OHRQoL (p = 0.009). Worse oral health status in children and adolescents with BCDH negatively impacts OHRQoL, and OHRQoL and quality of life analyzed from a generic perspective are positively correlated constructs in this population.

Factors associated with oral health-related quality of life among three-year old preschoolers in Vietnam

ABSTRACT Background Studies about oral health-related quality of life (OHRQoL) among preschool children in Vietnam are still limited. This study aimed to examine the OHRQoL of three-year preschool children and identify associated factors. Methods We performed a cross-sectional study in three kindergartens located in a city in the northern province of Vietnam from April to June 2021. A total of 361 children and their parents were enrolled in the study. The PedsQL™ Oral Health Scale was used to measure OHRQoL. Multivariate Tobit regression was used to determine factors associated with OHRQoL of children. Results The mean Oral PedsQOL score was 77.1 (SD = 17.6). Fathers’ high education and using milk daily (Coef. = 6.54, 95%CI = 1.91-11.16) were associated with higher OHRQoL. Meanwhile, a higher number of caries (Coef. = −0.73; 95%CI = −1.23; −0.23), a high frequency of experiencing bleeding gums, egg (Coef. = −5.76, 95%CI = −10.14; −1.38) and sweet food (Coef. = −4.94; 95%CI = −9.05; −0.83) as favorite foods were related to a lower OHRQoL. Children who brushed their teeth twice a day had a lower OHRQoL than those brushing once a day or less (Coef. = −4.40; 95%CI = −8.46; −0.34). Conclusion Preschoolers had moderate OHRQoL. Related factors include parental education, oral health and oral care behavior.

Development of the Oral Health Literacy Profile (OHLP)-Psychometric properties of the oral health and dental health system knowledge scales.

Current oral health literacy (OHL) instruments vary in focus, methodology, administration time and burden. The widely used word recognition tests fail to encompass important OHL domains, while others exceed time frames for use in practical settings, require an interviewer or mainly measure self-assessments. This paper describes the development of the Oral Health Literacy Profile (OHLP), introduces its components and evaluates the psychometric properties of its two core modules, the knowledge tests. A preliminary version of the questionnaire was developed and assessed for content validity, relevance and redundancy by an expert panel. It was tested in a convenience sample (n=95) leading to the creation of a 28-item questionnaire, which was afterwards tested in a second convenience sample (n=193). Item difficulty, discrimination, internal reliability and construct validity were assessed for the oral health knowledge (OHK) and dental health system knowledge (DHSK) modules. The items showed acceptable range of difficulty (ideal: 7 items; easy: 5 items; and difficult: 3 items) and good to very good discriminatory power (the point-biserial index (PBI) > 0.30: all items). Construct validity was considered to be fulfilled when 75% of the hypotheses of expected group differences were met. Satisfactory internal reliability was observed. With all its components, the OHLP is a suitable short instrument to assess the most relevant dimensions of the multifaceted construct of OHL. The OHLP can be widely used in research, especially suitable in practical settings, and thereby identify patients who may benefit from oral health education.

Adaptation and validation of the PEDSQL\u2122 oral health scale for toddlers in Chilean population

BackgroundThe Pediatric Quality of Life Inventory™ (PedsQL™) Oral Health Scale was developed to measure oral health-related quality of life (OHRQoL). The aim of this study was to cross-culturally adapt the parent-reported version for toddlers of PedsQL™ Oral Health Scale into Spanish and to assess the acceptability, reliability and validity of this version in Chilean preschool population.MethodsThe PedsQL™ Oral Health Scale for toddlers was cross-culturally adapted for the Spanish language using the recommended standards. To assess metric properties, a cross-sectional study was carried out with 301 children aged 2 to 5 years in Carahue, Chile. Chilean versions of the PedsQL™ Oral Health Scale, PedsQL™ 4.0 Generic Core Scales, and Early Childhood Oral Health Impact Scale (ECOHIS) were completed by the children’s parents. Dental caries, malocclusion and dental trauma were examined by trained dentists. The PedsQL™ Oral Health Scale was administrated a second time 14–21 days after. The reliability of the scale was verified by analysis of internal consistency (Cronbach’s alpha) and reproducibility (Intraclass correlation coefficient – ICC). The validity of the construct was assessed by confirmatory factor analysis and known groups method. The convergent validity was assessed by calculating the Spearman’s correlation with the ECOHIS questionnaire.ResultsThe PedsQL™ Oral Health Scale demonstrated good reliability, with Cronbach’s alpha coefficient of 0.79 and ICC of 0.85. A moderate-to-strong correlation was found between the PedsQL™ Oral Health Scale and the ECOHIS questionnaire (− 0.64); the PedsQL™ Oral Health Scale score was lower in children with poor than those with excellent/very good oral health (median 100 vs 85, p < 0.001); it also was lower in children with caries than in those caries-free (median 100 vs 90, p < 0.001). No statistically significant differences were found among groups according to malocclusion and traumatic dental injuries.ConclusionsThe PedsQL™ Oral Health Scale for toddlers in Spanish showed to be equivalent to the original version, and its psychometric properties were satisfactory for application in a Chilean pre-school population.

Health and oral health-related quality of life of children and adolescents with chronic kidney disease: a cross-sectional study.

The aim of this study was to evaluate if health and oral health status of children and adolescents with different stages of CKD are associated with their health-related quality of life (HRQoL), oral health-related quality of life (OHRQoL) and socioeconomic and demographic conditions. One hundred children and adolescents with CKD were age and gender matched to 100 individuals without CKD (mean age ± SD = 13.04 ± 2.57).Oral health was characterised by means of gingival bleeding index (GBI), plaque index (PI), the decayed, missing, and filled teeth(DMFT) index and the developmental enamel defect (DED) index. All children and adolescents answered two Peds QL® instruments (general and oral health scales). Comparing the mean scores of HRQoL and OHRQoL between groups, we observed that CKD group demonstrated worse perceptions when compared to non-CKD group. Multiple linear regression analysis with bootstrap estimation of variance (1000 replications) showed association between dental caries experience (p < 0.001), gingival inflammation (p < 0.001) and diagnosis of CKD (p = 0.027) with the OHRQoL and between physical and the emotional domain of HRQoL, when moderate/severe gingival inflammation and hypoplasia were present. The implementation of public policies that contemplate the early dental preventive intervention in CKD children and adolescents should occur aiming to improve their oral health, once oral manifestations can directly affect the aspects of the HRQoL and OHRQoL of these individuals.

Impact of Developmental enamel defects on quality of life in 5-year-old children.

Developmental enamel defects (DDE) represent one of the prevalent oral problems in childhood; however, few studies have evaluated its impact on quality of life in the children's own perception. To evaluate the DDE impact on quality of life of 5-year-old children. This cross-sectional observational study assessed 566 children aged 5years old, in Teresina, Piauí, Brazil, according to their self-perceptions. Children answered the Pediatric Quality of Life Inventory™ Version 4.0 and Oral Health Scale. The dmft index, modified DDE index and Foster and Hamilton criteria were used to diagnose dental caries, DDE and malocclusion, respectively. A single examiner performed the clinical examination. Descriptive analyses and Poisson regression with robust variance were performed. The prevalence of DDE was 33.7%. For children's self-reports, the presence of DDE had a negative association with oral health-related quality of life (OHRQoL; PR 1.09, 95% CI 1.02-1.15). Enamel hypoplasia had a negative impact on the physical function (PR 1.05; 95% CI 1.01-1.10) and oral health (PR 1.06, 95% CI 1.01-1.11) domains. Diffuse opacity had a negative impact on the social aspect (PR 1.09, 95% CI 1.02-1.18). Enamel defects had a negative impact on OHRQoL according to the self-reports of the children.

Cross-cultural adaptation and psychometric evaluation of the early childhood oral health impact scale (ECOHIS) in chilean population

BackgroundThe Early Childhood Oral Health Impact Scale (ECOHIS) measures the impact of dental diseases on Oral Health-Related Quality of Life both in children and their families. The aim of this study was to develop a Chilean Spanish version of the ECOHIS that is conceptually equivalent to the original and to assess its acceptability, reliability and validity in the preschool population of Chile.MethodsThe Chilean version of the ECOHIS was obtained through a process including forward and back-translation, expert panel, and cognitive debriefing interviews. To assess metric properties, a cross-sectional study was carried out in Carahue, Southern Chile (April–October 2016). Children younger than six years old without systemic diseases, disabilities or chronic medication from eleven public preschools were included. Parents were invited to complete the Chilean version of the ECOHIS, PedsQL™4.0 Generic Core and PedsQL Oral Health scales, and to answer global questions about their children’s general and oral health. A subsample was administrated ECOHIS a second time 14–21 days after. A clinical examination was performed to assess dental caries, malocclusion, and traumatic dental injuries. Reliability was evaluated using measures of internal consistency (Cronbach’s alpha) and reproducibility (Intraclass correlation coefficient - ICC). Construct validity was assessed by testing hypotheses based on available evidence about known groups and relationships between different instruments.ResultsThe content comparison of the back-translation with the original ECOHIS showed that all items except one were conceptually and linguistically equivalent. The cognitive debriefing showed a suitable understanding of the Chilean version by the parents. In the total sample (n = 302), the ECOHIS total score median was 1 (IQR 6), floor effect was 41.6%, and ceiling effect 0%. Cronbach’s alpha was 0.89 and the ICC was 0.84. The correlation between ECOHIS and PedsQL™4.0 Generic Core was weak (r = 0.21), while it was strong-moderate (r = 0.64) with the PedsQL Oral Health scale. In the known groups comparison, the ECOHIS total score was statistically higher in children with poor than excellent/very good oral health (median 11.6 vs 0, p < 0.01), and in the high severity than in the caries-free group (median 8 vs 0.5, p < 0.01). No differences were found according to malocclusion and traumatic dental injuries groups.ConclusionsThese results supported the feasibility, reliability and validity of the Chilean version of ECOHIS questionnaire for preschool children through proxy.

Perception of parents/caregivers on the oral health of children/adolescents with Down syndrome.

Oral health affects the general health of people with Down syndrome (DS), with repercussions on their ability to chew and to communicate. To evaluate the influence of sociodemographic characteristics and clinical indicators on the perceptions of parents/caregivers regarding the oral health of individuals with DS. Parents/caregivers completed a questionnaire containing sociodemographic information and answered the 20 questions of the Brazilian version of the Oral Health Scale for People with DS. Intra-oral clinical exam of children/adolescents was performed to assess dental caries, periodontal disease, and malocclusion. Descriptive statistics, bivariate analyses, and Poisson regression model analyses were carried out. In this study, 55.1% of the parents/caregivers showed a positive perception regarding the oral health of their children/adolescents. Parents/caregivers of individuals between 4 and 9 years old (Prevalence Ratio (PR)=1.13; Confidence Interval (CI),1.04 - 1.23; p=0.003) and parents/caregivers of those with definite malocclusion (PR=1.14; CI,1.00 - 1.31; p=0.047) had a higher prevalence of reporting a more negative perception of their children's/adolescents' oral health. DS individuals' age and the severity of malocclusion were indicators of a more negative perception of parents/caregivers regarding their sons'/daughters' oral health.

Parents' Perceptions of the Oral Health-related Quality of Life of their Autistic Children in Iran.

The aim of this study was to evaluate parents' perception of the oral health-related quality of life (OHRQoL) of autistic children in Iran, and to determine the quality of life of their families in relation to child' oral health status. 70 families with at least one child with autism, and 70 families with normal children were enrolled. Parents' perceptions of the OHRQoL of children were assessed using pre-validated PedsQL oral health scale questionnaire. PedsQL Family Impact Module questionnaire was also used to evaluate the impact of having an autistic child on the quality of life of their families. Both of the questionnaires were filled by parents. Parents of children with autism spectrum filled a separate questionnaire for the sibling of the autistic child. In the control families, child-reported PedsQL oral health scale questionnaire was also filled by the child himself/herself. Mann-Whitney U-test, and chi-square were used for statistical analysis. There was a significant difference in the mean total score of PedsQL oral health scale questionnaire between autistics and controls. Parents of normal children reported more oral problems (p<0.001). There was not a significant difference in the mean total score of PedsQL Family Impact Module questionnaire between the families of autistics and controls in the last 7 and 30 days. According to parents' point of view, oral health-related quality of life of autistic children was better than normal children. However, parents of autistic children had more problems in the social and communication issues.

Predictors of oral health-related quality of life in Iranian adolescents: A prospective study.

In the present study, we evaluated the direct and mediating (indirect) effects of clinical oral conditions, dental anxiety, sense of coherence (SOC), and socioeconomic variables on oral health-related quality of life (OHRQoL) and general health-related quality of life (GHRQoL) in Iranian adolescents. A longitudinal design was used with a sample of 1052 (694 males, mean age=15.05years) schoolchildren from Qazvin, Iran. Each participant completed a background information sheet and the following scales at baseline: Modified Dental Anxiety Scale, SOC, PedsQL 4.0 Generic Core Scale, and PedsQL Oral Health Scale. The PedsQL 4.0 Generic Core and Oral Health scales were recompleted at the 18-mo follow up. Father's education, monthly family income, dental anxiety, Community Periodontal Index (CPI), decayed, missing, and filled teeth (DMFT), and SOC significantly and directly predicted OHRQoL at 18mo. Father's education had indirect effects on OHRQoL through CPI and DMFT, family income had indirect effects through DMFT, and dental anxiety had indirect effects through CPI. OHRQoL at 18mo (β=0.499) and SOC (β=0.084) had significant and direct and mediating effects through OHRQoL on GHRQoL, while father's education, monthly family income, dental anxiety, CPI, and DMFT only showed mediating effects. Clinical oral indicators had direct effects on OHRQoL, but mediated the effects of dental anxiety and socioeconomic status on both OHRQoL and GHRQoL.

Sleep Bruxism and Anxiety Impacts in Quality of Life Related to Oral Health of Brazilian Children and their Families.

This study aimed to assess the impact of parent reported sleep bruxism, trait anxiety and sociodemographic/socioeconomic features on quality of life related to oral health (OHRQoL) of children and their families. Healthy children aged 3-7 years, with (n=34) and without (n=32) bruxism were select for this study. Data was collected by applying the following instruments: The Early Childhood Oral Health Scale (B-ECOHIS) and Trait-anxiety Scale (TAS). The sociodemographic/socioeconomic characteristics were obtained by interviews with parents. Multiple logistic regression tests were performed to observe the influence of sociodemographic/socioeconomic characteristics, bruxism and trait-anxiety on the children's OHRQoL. No association between sleep bruxism and all evaluated sociodemographic/socioeconomic conditions, with exception of being the only child (p=0.029), were observed. Mean B-ECOHIS and TAS scores were different (p<0.05) between children with (3.41 ± 4.87; 45.09 ± 15.46, respectively) and without (0.63 ± 1.28; 29.53 ± 11.82, respectively) bruxism. Although an association between bruxism and OHRQoL (p=0.015) was observed, it was dropped (p=0.336; OR=1.77) in the logistic regression model. Trait anxiety was the variable responsible for the impact on the OHRQoL of children (p=0.012; OR=1.05). Our results indicated anxiety as the main factor that interfered in the OHRQoL of children with sleep bruxism.

Rasch analysis of the Persian version of PedsQL(TM) Oral Health Scale: further psychometric evaluation on item validity including differential item functioning.

Background: The study aimed to further evaluate the psychometric properties of one recently developed oral health related quality of life (OHRQoL) instrument (PedsQL Oral Health Scale), including student self-report and parent-proxy report. Specifically, we tested the item validity,threshold order, local dependency, and differential item functioning (DIF) across gender and rater. Methods: This is a cross-sectional study, and study population was recruited in Qazvin, Iran using one-stage sampling with the unit of school. Students and their parents (1529 dyads) separately completed the Persian version of PedsQL Oral Health Scale. The psychometric properties were analyzed using Rasch rating scale model, including item validity, threshold order for response categories, and DIF across gender (boys vs. girls in student self-report) and rater (student self report vs. parent-proxy report). Results: All items had satisfactory in fit and outfit mean square error. One disordering category (the response of often) was found in parent-proxy report, while all categories were ordered in student self-report. All items were DIF-trivial across gender and rater. Conclusion: PedsQL Oral Health Scale is a valid instrument to measure OHRQoL. However, our results indicated that the parent-proxy report was inferior to the student self-report, and healthcare providers should primarily use the student self-report.

Oral Health Scales: design of an oral health scale of infectious potential.

Objectives: In this paper we propose a new Global Oral Health Scale that will allow the infectious potential of the oral cavity, clinically manifest as local and focal infections, to be condensed into a single parameter. Study Design: Based on a number of oral health scales previously designed by our group, we designed a final version that incorporates dental and periodontal variables (some of them evaluated using corroborated objective indices) that reflect the presence of caries and periodontal disease. Results: The application of the proposed oral health scale requires the examination of 6 sites per tooth (mesio-buccal, medio-buccal, disto-buccal, disto-lingual, medio-lingual and mesio-lingual). The following variables are analysed: number of tooth surfaces with supragingival plaque, determined using the O’Leary index; number of teeth with caries and the severity of the caries; number of tooth surfaces with gingival inflammation, determined using the Ainamo and Bay index; and number of tooth surfaces with pockets ?4 mm and severity of the pockets. These variables are then grouped into 2 categories, dental and periodontal. The final grades of dental and periodontal health correspond to the grades assigned to a least 2 of the 3 variables analysed in each of these categories. The category (dental or periodontal) with the highest grade is the one that determines the grade of the Global Oral Health Scale. Conclusion: This scale could be particularly useful for the epidemiological studies comparing different populations and for analysis of the influence of distinct degrees of oral health on the development of certain systemic diseases. Key words:Scale, oral health, infectious potential, systemic disease.

Evaluation of an oral health scale of infectious potential using a telematic survey of visual diagnosis

Objective: To compare the results of a subjective estimation of oral health through review of a set of intraoral photographs with those of an objective oral health scale of infectious potential. Method: The pool of patients was made up of 100 adults. Using an infectious-potential scale based on dental and periodontal variables, we assigned 1 of the 4 grades of the scale (range, 0 to 3; 0 corresponds to an excellent oral health status and 3 to the poorest oral health status) to each subject. A total of 20 representative subjects were selected from the pool of patients, 5 subjects for each one of the grades of the scale, and a standardized photographic record was made. One thousand dentists practicing in Spain were sent the survey by e-mail and 174 completed forms were received. We then calculated the concordance of the oral health status indicated by the respondents after visualising the photographs on comparison with the results of the oral health scale of infectious potential; concordance was termed correct grade allocation (CGA). Results: The majority of respondents (69.1%) achieved a CGA in 8 to 12 cases and none achieved more than 15 CGAs. The poorest CGA rates were found with grades 1 and 2, with a mean of 1.74 ± 1.09 and 1.87 ± 1.18, respectively, out of a maximum of 5. The concordance in terms of CGA was high for grade 0 (70.5%), very low for grade 1 (10.8%), low for grade 2 (37.3%), and moderate for grade 3 (42.6%). Conclusion: In comparison with visual examination of the oral cavity, the use of objective scale that establishes a reliable diagnosis of oral health in terms of infectious potential was found to be advantageous. Key words:Diagnosis, intraoral photographies, oral health scale, objective estimation, visual examination.

Evaluation of partial-mouth recording systems of gingival parameters in a Portuguese adult population

To analyze the diagnostic reliability of various partial-mouth recording systems (PMRS) for the simultaneous assessment of supragingival plaque, calculus, and gingival inflammation in a population of Portuguese adults. A single examiner determined the levels of plaque, calculus, and gingival inflammation in 108 subjects using quantitative and dichotomous indices. Half-mouth and ≤ 10-tooth PMRS were compared with full-mouth examination (FME). On comparison with FME, Q1+Q3, Q1+Q4, Q2+Q3, Q2+Q4 combinations and the Ramfjord teeth did not show statistically significant differences in the simultaneous assessment of plaque, calculus, and gingival inflammation using both quantitative and dichotomous indices. Comparison of the prevalence of subjects that presented discrepancy in the three clinical parameters between FME and PMRS, Q1+Q3 combination was associated with lower percentages of discrepancy (range of discrepancies=0.9-6.4 percent) and a higher specificity (≥ 0.90) and sensitivity (≥ 0.89). The Q1+Q3 combination could be particularly applicable in studies investigating relationships between the state of gingival health and environmental or patient-related systemic factors, as well as in the development of oral health scales that include gingival parameters.

The PedsQL™ Oral Health Scale: feasibility, reliability and validity of the Brazilian Portuguese version.

BackgroundOral and orofacial problems may cause a profound impact on children’s oral health-related quality of life (OHRQoL) because of symptoms associated with these conditions that may influence the physical, psychological and social aspects of their daily life. The OHRQoL questionnaires found in the literature are very specific and are not able to measure the impact of oral health on general health domains. Consequently, the objective of this study was to evaluate the psychometric properties of the Portuguese version for Brazilian translation of the Pediatric Quality of Life Inventory™ (PedsQL™) Oral Health Scale in combination with the PedsQL™ 4.0 Generic Core Scales.MethodsThe PedsQL™ Oral Health Scale was forward-backward translated and cross-culturally adapted for the Brazilian Portuguese language. In order to assess the feasibility, reliability and validity of the Brazilian version of the instrument, a study was carried out in Belo Horizonte with 208 children and adolescents between 2 and 18 years-of-age and their parents. Clinical evaluation of dental caries, socioeconomic information and the Brazilian versions of the PedsQL™ Oral Health Scale, PedsQL™ 4.0 Generic Core Scales, Child Perceptions Questionnaire (CPQ11-14 and CPQ8-10) and Parental-Caregiver Perception Questionnaire (P-CPQ) were administered. Statistical analysis included feasibility (missing values), confirmatory factor analysis (CFA), internal consistency reliability, and test-retest intraclass correlation coefficients (ICC) of the PedsQL™ Oral Health Scale.ResultsThere were no missing data for both child self-report and parent proxy-report on the Brazilian version of the PedsQL™ Oral Health Scale. The CFA showed that the five items of child self-report and parent proxy-report loaded on a single construct. The Cronbach's alpha coefficients for child/adolescent and parent oral health instruments were 0.65 and 0.59, respectively. The test-retest reliability (ICC) for child self-report and parent proxy-report were 0.90 [95% confidence interval (CI) = 0.86-0.93] and 0.86 (95%CI = 0.81-0.90), respectively. The PedsQL™ Oral Health Scale demonstrated acceptable construct validity, convergent validity and discriminant validity.ConclusionsThese results supported the feasibility, reliability and validity of the Brazilian version of the PedsQL™ Oral Health Scale for child self-report for ages 5–18 years-old and parent proxy-report for ages 2–18 years-old children.

The PedsQL™ Oral Health Scale in Iranian children: reliability and validity

The primary objective of the study was to translate and evaluate the psychometric properties of the Pediatric Quality of Life Inventory™ (PedsQL™) Oral Health Scale in over 1000 Iranian children. A standard forward and backward translation procedure was used to convert the US English dialect version of the PedsQL™ Oral Health Scale into the Iranian language (Persian). The Iranian version of the PedsQL™ Oral Health Scale, in combination with the PedsQL™ 4.0 Generic Core Scales, was then subsequently administered to 1053 Iranian children and 1026 parents. The reliability of the PedsQL™ Oral Health Scale was evaluated using internal consistency and test-retest methods. Known-groups discriminant validity, exploratory factor analysis (EFA) of the Oral Health and the four Generic Core Scales combined, and confirmatory factor analysis (CFA) of the Oral Health Scale alone were conducted. The Benjamini-Hochberg procedure was used to correct P-values for multiple comparisons. Good to excellent internal consistency and test-retest reliabilities were demonstrated. The PedsQL™ Oral Health Scale demonstrated discriminant validity for subgroups of children across different decayed, missing and filled teeth (DMFT) index categories and gender. The EFA supported the a priori factor model of the combined five scales. The CFA analysis confirmed the unidimensional factor structure of the Oral Health Scale. The PedsQL™ Oral Health Scale demonstrated excellent psychometric properties in combination with the PedsQL™ 4.0 Generic Core Scales. These five scales combined can be utilized to assess the multidimensional oral-health-related quality of life of Iranian children.

Reliability and Validity of the PedsQL™ Oral Health Scale: Measuring the Relationship Between Child Oral Health and Health-Related Quality of Life

This study examined the reliability and validity of the Pediatric Quality of Life Inventory™ (PedsQL) Oral Health Scale, a 5-item measure of child self-reported and parent-proxy reported pediatric oral health. One hundred twenty-six families participated during Phase 1 of the study, and 34 during Phase 2. Internal consistency and agreement between parent and child reports were examined. The construct, criterion-related, and convergent validity of the measure was supported by the results of this study. Using the PedsQL Oral Health Scale and the PedsQL 4.0 Generic Core Scales provide a generic health-related quality of life assessment that captures the physical, emotional, social, school, and oral domains of health.
