Objectives: Network analysis is an innovative, analytic approach that enables visual representation of variables as nodes and their corresponding statistical associations as edges. It also provides a new way of framing oral health-related questions as complex systems of variables. We aimed to generate networks of oral health variables using epidemiological data of Indigenous children, and to compare network structures of oral health variables among participants who received immediate or delayed delivery of an oral health intervention., Methods: Epidemiological data from 448 mother-child dyads enrolled in a randomized controlled trial of dental caries prevention in South Australia, Australia, were obtained. Networks were estimated with nodes representing study variables and edges representing partial correlation coefficients between variables. Data included dental caries, impact on quality of life, self-rated general health, self-rated oral health, dental service utilization, knowledge of oral health, fatalism and self-efficacy in three time points. Communities of nodes, centrality, clustering coefficient and network stability were estimated., Results: The oral health intervention interacted with the network through self-rated general health and knowledge of oral health. Networks depicting groups shortly after receiving the intervention presented higher clustering coefficients and a similar arrangement of nodes. Networks tended to return to a preintervention state., Conclusion: The intervention resulted in increased connectivity and changes in the structure of communities of variables in both intervention groups. Our findings contribute to elucidating dynamics between variables depicting oral health networks over time., (© 2021 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objective: To develop and validate a 4-item child oral health-related quality of life (OHRQoL) instrument that might be more amenable for uptake in large scale, multifaceted surveys of children's health and wellbeing than current, longer-form child OHRQoL instruments., Methods: Data were obtained from a study of the South Australian School Dental Service population designed to investigate OHRQoL among school children aged 8-13 years in 2002-2003. The Child Perception Questionnaire (CPQ8-10 and CPQ11-14) was utilised, which comprises 25 & 37 items representing four conceptual domains: oral symptoms, functional limitations, emotional wellbeing and social wellbeing. Initially, the psychometric properties of the short form 8-item CPQ were tested in both age groups using Confirmatory Factor Analysis. The rationale was that, if the 8-item CPQ8-10 and CPQ11-14 did not display good psychometric properties, there was no reason to proceed with further shortening into 4-item versions. Following a good fit of the 8-item CPQ, items with higher factor loadings in each domain were maintained and tested in the development of a 4-item CPQ. Exploratory Factor Analysis was conducted to determine dimensionality, followed by tests for reliability and validity. Model fits were assessed using Root Mean Square Error of Approximation (RMSEA), Comparative Fit Index (CFI) and Standardized Root Mean Square Residual (SRMR)., Results: There were 308 children aged 8-10 years who completed CPQ8-10 and 461 children aged 11-13 years who completed CPQ11-14. For the short-form 8-item instrument, satisfactory goodness of fit was demonstrated for the two age groups, with acceptable thresholds for RMSEA, CFI, and SRMR. The four items with the highest factor loading in each domain were the same for the 8-item CPQ8-10 and CPQ11-14. and these items were selected to comprise the 4-item CPQ8-10 and CPQ11-14. The 4-item short form displayed good criterion validity, with expected score patterns found in the majority of the known groups evaluated., Conclusions: We developed short-form 4-item CPQ8-10 and CPQ11-14 instruments that were tested in a large convenience sample of South Australian school children. The instruments demonstrated acceptable reliability and validity. Implications for practice are discussed., Competing Interests: The authors have no competing interests to declare.

The aim of this systematic review and meta-analysis was to document the disparity in dental caries experiences among indigenous and nonindigenous populations globally by measuring dental caries prevalence and severity. An electronic database (MEDLINE) was initially searched using relevant keywords. This was followed by use of the search string in the following electronic databases: Scopus, EBSCOhost, Cochrane, and Open Grey. Two independent reviewers conducted the study search and screening, quality assessment, and data extraction, which was facilitated using JBI SUMARI software. The primary outcome was the decayed missing filled teeth (DMFT) score and dental caries prevalence. Subgroup analysis was done by country of publication to identify causes of heterogeneity. Forest plots were used with the standardized mean difference (SMD) and publication bias was assessed using the Egger test with funnel plot construction. For the final review, 43 articles were selected and 34 were meta-analyzed. The pooled mean DMFT for both the permanent dentition (SMD = 0.26; 95% CI 0.13-0.39) and deciduous dentition (SMD = 0.67; 95% CI 0.47-0.87) was higher for the Indigenous population than for the general population. Indigenous populations experienced more decayed teeth (SMD = 0.44; 95% CI 0.25-0.62), a slightly higher number of missing teeth (SMD = 0.11< 95% CI -0.05 to 0.26), and lesser filled teeth (SMD = -0.04; 95% CI -0.20 to 0.13) than their nonindigenous counterparts. The prevalence of dental caries (SMD = 0.27; 95% CI 0.13-0.41) was higher among indigenous people. Globally, indigenous populations have a higher caries prevalence and severity than nonindigenous populations. The factors which have led to such inequities need to be examined.

Objectives: To evaluate the replicability of oral health literacy (OHL) network models across the general community and a sample of older adults from Brazil.Methods: Data were obtained from two oral health surveys conducted with a total of 1138 participants. OHL was measured using the short form Health Literacy in Dentistry scale (HeLD-14). A regularized partial correlation network was estimated for each sample. Dimensionality and structural stability were examined via exploratory graph analysis. Network properties compared included global strength, edge weights, and centrality estimates. Model replicability was examined fitting the general community model to the older participants' data.Results: Six dimensions with the exact same item composition were detected in both network models. Only the Receptivity domain in the older adults sample yielded low structural stability. Strong correlations were observed between edge weights (τ: 0.68; 95% CI: 0.62-0.74) and between node strength estimates (τ: 0.63; 95% CI: 0.36-0.89). No statistically significant differences were found for global strength. The fit of the older adults sample to the HeLD-14 network structure of the general community sample was satisfactory.Conclusion: Network models OHL replicated across the general community and a sample of older adults. The psychometric network approach is a useful tool to evaluate the measurement equivalence of OHL instruments across populations. [ABSTRACT FROM AUTHOR]
