Examining the association between untreated caries in children and parent fluoride treatment refusal.

BACKGROUND: In this case-control study, the authors examined the relationship between untreated caries in children and parent fluoride treatment refusal. The authors hypothesized that parents of children with a history of untreated caries would be less likely to refuse topical fluoride for their children than parents of children with no history of untreated caries. METHODS: The study included children (≤ 18 years old) who were patients at a university dental clinic from January 2016 through June 2020. Children whose parents refused fluoride treatment were age-matched with children whose parents did not refuse fluoride treatment (n = 356). The outcome variable was parent topical fluoride refusal for their children (no, yes). The predictor variable was a history of untreated caries (no, yes). Confounding variable-adjusted modified Poisson regression models were used to estimate the prevalence ratio of parent fluoride refusal by means of children's untreated caries status. RESULTS: Approximately 46.3% of children had a history of untreated caries. The prevalence of parent fluoride refusal for children with a history of untreated caries was significantly lower than that for children with no history of untreated caries (adjusted prevalence ratio, 0.79; 95% CI, 0.63 to 0.98; P = .03). CONCLUSIONS: Parents of children with a history of caries are less likely to refuse topical fluoride treatment, which suggests that untreated caries may motivate parents to accept preventive dental treatments like fluoride. PRACTICAL IMPLICATIONS: Dental care professionals should assess caries risk and communicate a child's caries risk before making a recommendation regarding topical fluoride treatment.

Socioeconomic vulnerability and access to community water fluoridation in Washington.

BACKGROUND: The aim of the authors was to determine whether socioeconomic vulnerability is associated with community water fluoridation (CWF). METHODS: The authors used US Census Bureau data to create 4 county-level vulnerability markers (percentages non-White, Hispanic or Latino, below the federal poverty threshold, education below high school), obtained county-level CWF data from the Washington State Department of Health, and evaluated associations using Spearman rank correlation coefficient and the Kruskal-Wallis rank sum test. The authors then interviewed 122 community members in Washington (December 2022-March 2023) and analyzed the interview data inductively. RESULTS: A higher percentage of non-White people at the county level was associated with a significantly higher level of CWF (Spearman rank correlation coefficient, 0.55; 95% CI, 0.29 to 0.82; P < .001), whereas county-level poverty was associated with significantly lower CWF (Spearman rank correlation coefficient, -0.36; 95% CI, -0.70 to -0.03; P = .02). High school completion was not associated with county-level CWF. Significantly larger proportions of Hispanics and Latinos lived in counties with higher CWF (P < .05). From the interviews, more participants thought tap water was healthy than unhealthy, but 41% had mixed feelings. Similarly, more participants thought CWF was acceptable than unacceptable, with 35% reporting mixed feelings. Negative views about tap water and CWF were more common among non-White participants. CONCLUSIONS: People in racially and ethnically diverse communities in Washington appear to have greater access to CWF, whereas those in lower-income communities have poorer access. PRACTICAL IMPLICATIONS: CWF is an important population-level strategy to prevent caries. Additional work is needed to improve access to CWF, especially for people from low-income communities.

The association between cystic fibrosis-related diabetes and periodontitis in adults: A pilot cross-sectional study.

OBJECTIVES: Periodontitis is a highly prevalent complication of diabetes. However, the association between cystic fibrosis-related diabetes (CFRD) and periodontitis has not yet been evaluated. The objective of this study was to assess if: 1) CFRD is associated with periodontitis among adults with CF, and 2) periodontitis prevalence differs by CF and diabetes status. METHODS: This was a pilot cross-sectional study of the association between CFRD and periodontitis in adults with cystic fibrosis (CF) (N = 32). Historical non-CF controls (N = 57) from the U.S. National Health and Nutrition Examination Survey (NHANES) dataset were frequency matched to participants with CF on age, sex, diabetes status, and insulin use. We defined periodontitis using the U.S. Centers for Disease Control and Prevention and the American Academy of Periodontology (CDC/AAP) case definition, as the presence of two or more interproximal sites with CAL ≥3 mm and two or more interproximal sites with PD ≥4 mm (not on the same tooth) or one site with PD ≥5 mm. Because NHANES periodontal data were only available for adults ages ≥30 years, our analysis that included non-CF controls focused on this age group (CF N = 19, non-CF N = 57). Based on CF and diabetes status, we formed four groups: CFRD, CF and no diabetes, non-CF with diabetes, and non-CF and no diabetes (healthy). We used the Fisher's exact test for hypotheses testing. RESULTS: There was no association between CFRD and periodontitis for participants with CF ages 22-63 years (CFRD 67% vs. CF no diabetes 53%, P = 0.49), this was also true for those ages ≥30 years (CFRD 78% vs. CF no diabetes 60%, P = 0.63). For the two CF groups, the prevalence of periodontitis was significantly higher than for healthy controls (CFRD 78% vs. healthy 7%, P<0.001; CF no diabetes 60% vs. healthy 7%, P = 0.001) and not significantly different than the prevalence for non-CF controls with diabetes (CFRD 78% vs. non-CF with diabetes 56%, P = 0.43; CF no diabetes 60% vs. non-CF with diabetes 56%, P = 0.99). CONCLUSION: Among participants with CF, CFRD was not associated with periodontitis. However, regardless of diabetes status, participants with CF had increased prevalence of periodontitis compared to healthy controls.

Food insecurity and its relationship to mental health and oral health in older adults.

BACKGROUND AND OBJECTIVES: Poor oral health disproportionately affects low-income older adults, for whom food insecurity and poor mental health may affect dental health. We explored the associations between food insecurity, mental health, and dental health. Furthermore, we examined whether mental health impacted the associations between food insecurity and dental health. MATERIALS AND METHODS: We conducted a cross-sectional study with a convenience sample of 226 older adults (aged 50+), employing survey and dental screening data. Participants were recruited from seven community-based organisations in Washington State, USA. We calculated descriptive statistics and conducted Chi-square tests, t tests, and logistic regression analyses to assess the associations between aspects of dental health (untreated decay, gum disease, and unmet dental needs), mental health (depression and cognitive function), and food insecurity. RESULTS: In our sample, food insecurity was observed in 28.4%, 40.6% had untreated decay, 31.6% gum disease, and 42.5% unmet dental needs. Food insecurity was associated with a higher occurrence of untreated decay and unmet dental needs. Participants experiencing food insecurity had higher odds of gum disease (aOR = 2.3; 95% CI: 1.1, 5.2) and unmet dental needs (aOR = 3.2; 95% CI:1.4, 7.6). Greater gum disease due to food insecurity was observed among individuals with lower levels of cognitive impairment. CONCLUSION: Food insecurity is associated with poorer oral health among older adults and cognitive function may modify this relationship. These findings underscore the importance of addressing both food insecurity and cognitive impairment as integral components of efforts to improve the oral health of older adults.

Association between food insecurity and edentulism for older adults: A pilot study.

OBJECTIVES: This pilot study examined the association between food insecurity and edentulism among older adults in Washington State. METHODS: This study focused on adults aged 50 years and older, who were recruited through seven community-based organizations in Washington State. The exposure variable was food security level (high, marginal, and low/very low food security) assessed using the 10-item U.S. Adult Food Security Survey. The outcome was edentulism, defined as having zero natural teeth. Confounder-adjusted odds ratios (OR) and 95% confidence intervals (CIs) were generated using binary logistic regression models (α = 0.05). RESULTS: Of the 216 participants, 28.7% (n = 62) had low/very low food security and 7.9% (n = 17) had zero teeth. Older adults with low or very low food security had greater odds of being edentulous compared to those with marginal or high food security, although the difference was not statistically significant (OR: 1.39; 95% CI: 0.46, 4.20; p = 0.56). CONCLUSIONS: Future research should explore food insecurity-focused interventions aimed at preventing edentulism in older adults in a broader effort to address oral health inequities.

Identifying sources of variation in added sugar intake for Alaska Native children using a hair biomarker.

Sugars from sugar-sweetened beverages (SSBs) are an important risk factor for tooth decay. The study goal was to determine if there was variation in added sugar intake across communities and between and within households. In this cross-sectional study, intakes of total sugar, added sugar, and sugar-sweetened beverages (SSBs) were estimated for 282 Alaska Native children ages 0-10 years from 131 households in three Yukon-Kuskokwim (YK) Delta communities using biomarker equations based on hair carbon and nitrogen isotope ratios previously developed for the Yup'ik population. ANOVA was used to assess associations between each predictor (community and household) and outcome (estimated total sugars, added sugars, and SSB intake). Between- and within-household variation was estimated using a linear mixed-effects model with a random intercept for households with three or more children. There was no significant difference in mean estimated total sugar (p = 0.29), added sugar (p = 0.24), or SSB intake (p = 0.40) across communities. Significant variations were observed between and within households, with within-household variation amounting to 59% of the between-household variation. Added sugar intake in Alaska Native children from the three study communities is higher than the recommended maximum, and the variation is greater within households than between households.

Saliva sampling method influences oral microbiome composition and taxa distribution associated with oral diseases.

Saliva is a readily accessible and inexpensive biological specimen that enables investigation of the oral microbiome, which can serve as a biomarker of oral and systemic health. There are two routine approaches to collect saliva, stimulated and unstimulated; however, there is no consensus on how sampling method influences oral microbiome metrics. In this study, we analyzed paired saliva samples (unstimulated and stimulated) from 88 individuals, aged 7-18 years. Using 16S rRNA gene sequencing, we investigated the differences in bacterial microbiome composition between sample types and determined how sampling method affects the distribution of taxa associated with untreated dental caries and gingivitis. Our analyses indicated significant differences in microbiome composition between the sample types. Both sampling methods were able to detect significant differences in microbiome composition between healthy subjects and subjects with untreated caries. However, only stimulated saliva revealed a significant association between microbiome diversity and composition in individuals with diagnosed gingivitis. Furthermore, taxa previously associated with dental caries and gingivitis were preferentially enriched in individuals with each respective disease only in stimulated saliva. Our study suggests that stimulated saliva provides a more nuanced readout of microbiome composition and taxa distribution associated with untreated dental caries and gingivitis compared to unstimulated saliva.

Validating a Conceptual Model on Topical Fluoride Hesitancy With Latino Parents.

Fluoride hesitancy is a growing public health challenge and interventions to address it may need to be tailored for minoritized subgroups to address oral health inequities. The goals of this qualitative study were to investigate the extent to which an existing conceptual model on topical fluoride hesitancy is applicable to Latino parents and whether applicability differed between Spanish-speaking Latino (SL) and English-speaking Latino (EL) parents. We conducted semi-structured one-on-one interviews with non-Latino English-speaking parents (N = 50), SL parents (n = 8), and EL parents (n = 8). We coded the transcripts deductively and compared our findings both qualitatively and quantitatively to an existing model on topical fluoride hesitancy comprising 21 categories classified into six domains. We compared frequencies across model domains and categories for Latino versus non-Latino parents as well as for SL versus EL parents. Latino parents were represented across all six domains and 21 categories of the conceptual model. Comparing Latino and non-Latino parents, representation was similar across Domains 1 to 3 (necessity, chemicals, and harm); Latino parents were more highly represented in Domains 4 to 6 (uncertainty, pressure, and choice) compared with non-Latino parents. A larger proportion of EL parents thought a healthy diet was more important than fluoride (Category 1d) and a larger proportion of SL parents felt they did not know enough about fluoride (Category 4a). An existing conceptual model on topical fluoride hesitancy was generally a good fit for SL and EL parents. However, differential representation across model categories suggests that fluoride-related communication and intervention approaches may need to be tailored to Latino parents based on language preference.

Psychometric properties of the Fluoride Hesitancy Identification Tool (FHIT).

INTRODUCTION: Some caregivers are hesitant about topical fluoride for their children despite evidence that fluoride prevents caries and is safe. Recent work described a five domain model of caregivers' topical fluoride hesitancy. We developed the Fluoride Hesitancy Identification Tool (FHIT) item pool based on the model. This study sought to evaluate the FHIT's psychometric properties in an effort to generate a short, simple to score, reliable, and valid tool that measures caregivers' topical fluoride hesitancy. METHODS: In 2021 and 2022, we conducted an observational, cross-sectional study of caregivers, collecting data from two independent caregiver samples (n1 = 523; n2 = 612). The FHIT item pool included 33 items. We used confirmatory factor analyses (CFA) to examine whether the FHIT items measured five separate domains as hypothesized and to reduce the number of items. We then fit item response theory (IRT) models and computed Cronbach's alpha for each domain. Last, we examined the construct validity of the FHIT and evaluated scoring approaches. RESULTS: After dropping 8 items, CFA supported a five factor model of topical fluoride hesitancy, with no cross-loadings (RMSEA = 0.079; SRMR = 0.057; CFI = 0.98; TLI = 0.98). We further reduced the items to four per domain (20 items total). Marginal alphas showed that the item sets provided reliability of ≥0.90 at hesitancy levels at and above average. The domains correlated more strongly with each other and topical fluoride refusal than with other questions on the survey. DISCUSSION: Our results support the FHIT's ability to reliably and validly measure five domains of topical fluoride hesitancy using the average score of the four items in each domain.

A Mixed-Methods Study on Topical Fluoride Beliefs and Refusal Behaviors for Caregivers of Children with Special Health Care Needs.

OBJECTIVE: To understand topical fluoride-related beliefs and refusal behaviors for caregivers of children with special health care needs (CSHCN). METHODS: This was an explanatory sequential mixed methods study. For the quantitative analyses, we surveyed 520 caregivers to (a) compare fluoride-related beliefs between caregivers of CSHCN and caregivers of healthy children and (b) evaluate the association between special health care need (SHCN) status and topical fluoride refusal. We used logistic regression models to generate unadjusted odds ratios, confounder-adjusted odds ratios (AOR), and 95% confidence intervals (CI). For the qualitative analyses, we interviewed 56 caregivers who refused or were hesitant about topical fluoride. Data were coded deductively and compared by SHCN status to an existing conceptual model of topical fluoride refusal. RESULTS: In the quantitative analysis, 41.3% of caregivers refused or thought about refusing topical fluoride. There were no significant differences in fluoride beliefs by SHCN status (p-values > 0.05) nor was there a significant association between SHCN status and topical fluoride refusal (AOR: 0.65, 95% CI 0.37-1.14; p = 0.13). In the qualitative analysis, the relative importance of each domain of the conceptual model was similar between the caregiver groups. Two differences were that all caregivers of CSHCN thought fluoride was unnecessary and wanted to keep chemicals out of their child's body. CONCLUSIONS FOR PRACTICE: While caregivers of CSHCN were not more likely to refuse topical fluoride than caregivers of healthy children, there may be important differences in the underlying reasons for refusing topical fluoride.

Sugar-sweetened beverage intake and convenience store shopping as mediators of the food insecurity-Tooth decay relationship among low-income children in Washington state.

INTRODUCTION: There are oral health disparities in the U.S. and children in food-insecure households have a higher burden of tooth decay. Identifying the mechanisms underlying the food insecurity-tooth decay relationship could inform public health interventions. This study examined how sugar-sweetened beverage (SSB) intake and frequent convenience store shopping mediated the food insecurity-tooth decay relationship for lower-income children. MATERIALS AND METHODS: Cross-sectional study data included a household survey, beverage questionnaire, and dental examination. The sample included 452 lower-income, racially-diverse, child-caregiver dyads in 2018 from King County in Washington state. The exposure was household food insecurity, the outcome was untreated decayed tooth surfaces, and the proposed mediators were SSB intake and frequent convenience store shopping (≥2 times/week). Causal mediation analyses via the potential outcomes framework was used to estimate natural indirect and direct effects. RESULTS: Fifty-five percent of participants were in food-insecure households, the mean number of decayed tooth surfaces among children was 0.87 (standard deviation [SD] = 1.99), the mean SSB intake was 17 fluid ounces (fl/oz)/day (SD = 35), and 18% of households frequently shopped at a convenience store. After adjusting for confounders, household food insecurity and log-transformed SSB intake (fluid ounces/day) were positively associated with decayed tooth surfaces, but not at the a α = 0.05 level (mean ratio [MR] 1.60; 95% confidence interval [CI] 0.89, 2.88; p = .12 and MR 1.16; 95% CI 0.93, 1.46; p = .19, respectively). Frequent convenience store shopping was associated with 2.75 times more decayed tooth surfaces (95% CI 1.61, 4.67; p < .001). SSB intake mediated 10% of the food insecurity-tooth decay relationship (p = .35) and frequent convenience store shopping mediated 22% (p = .33). CONCLUSIONS: Interventions aimed at addressing oral health disparities in children in food-insecure households could potentially focus on reducing intake of SSBs and improving access to healthful foods in lower-income communities.

Preventive dental care utilization and dental caries for Medicaid-enrolled adolescents in Oregon.

OBJECTIVES: This study aimed to evaluate the relationship between preventive dental care utilization and untreated dental caries for Medicaid-enrolled adolescents and to determine if the relationship is moderated by chronic conditions (CC). METHODS: This analysis was based on 2015-2016 Medicaid claims files and survey data collected from adolescents ages 12-18 years enrolled in Oregon Medicaid, who received a dental screening between December 2015 and December 2016 (n = 240). To assess the relationship between preventive dental care utilization and untreated dental caries (defined as decayed tooth surfaces), prevalence ratios (PR) and 95% confidence intervals (CI) were generated using log-linear regression models. We also tested for an interaction between preventive dental care utilization and CC. RESULTS: About 60.4% of adolescents utilized preventive dental care, 21.7% had CC, and 29.6% had ≥1 decayed tooth surfaces. There were no significant differences in untreated dental caries between adolescents who did and did not utilize preventive dental care (PR: 0.73, 95% CI: 0.33-1.60; p = 0.43). There was not a significant interaction between preventive dental care utilization and CC (p = 0.65). Preventive dental care utilization was not significantly associated with untreated dental caries for adolescents with CC (PR: 0.51, 95% CI: 0.10-2.65; p = 0.42) nor among adolescents without CC (PR: 0.79, 95% CI: 0.33-1.91; p = 0.61). CONCLUSIONS: Preventive dental care was not shown to be associated with lower untreated dental caries for Medicaid-enrolled adolescents or those with CC. Future work that is adequately powered should continue to elucidate this relationship in Medicaid enrollees.

A Qualitative Assessment of Factors Influencing Fluoride-Hesitant Parents' Trust of Dentists.

PURPOSE: The purpose of this study was to use fluoride-hesitant parents as a model to identify the factors that erode versus build trust in their child's dentists. METHODS: A qualitative study was conducted using a semi-structured interview guide with fluoride-hesitant parents recruited from two dental clinics and through snowball sampling. A content analysis was performed to identify factors that erode versus build parents' trust in their child's dentist. RESULTS: Of the 56 parents interviewed, most were female (91.1 percent) and white (57.1 percent) and had a mean age of 41±9.7 (standard deviation) years. Factors identified included five that erode trust (having trust violated previously, sensing discrepancies, getting pushed to accept fluoride, feeling dismissed, and sensing bias) and four that build trust (being treated as an individual, having a dentist who communicates, feeling supported and respected, and having a choice). CONCLUSIONS: Dentists' understanding of the factors that erode and build trust with parents could help providers develop patient-centered communication strategies.

Periodontitis Risk Factors in Adults with Cystic Fibrosis: A pilot study.

Purpose Individuals with cystic fibrosis (CF) present with multiple condition-specific risk factors for periodontitis including CF-related diabetes, chronic inhaled treatments that induce xerostomia, and increased systemic inflammation because of frequent lung infections. General factors like age, oral hygiene, and diet may also contribute to the risk of periodontitis. However the relative importance of these specific risk factors and periodontitis in individuals with CF has not yet been evaluated. The purpose of this pilot study was to assess the associations between CF condition-specific and general risk factors and the prevalence of periodontitis in adults with CF.Methods This cross-sectional pilot study was designed to assess a multifactorial model of periodontitis risk factors in a population in adults with CF who were recruited from the University of Washington Adult CF center. Periodontitis was defined using the Centers for Disease Control and Prevention and the American Academy of Periodontology (CDC/AAP) case definition. Risk factors included condition-specific and general factors. Differences between participants with moderate/severe periodontitis and those with no/mild periodontitis was assessed using the Mann-Whitney test, the Fisher's exact test, and the exact chi-square test (α=0.05).Results Thirty-two participants were enrolled. Twenty-eight percent of the participants had moderate periodontitis, 72% had no/mild periodontitis; none of the participants had severe periodontitis. There were no significant differences in condition-specific factors between between the two study groups. Participants with moderate periodontitis were older (p=0.028) and reported daily flossing in higher proportions than those with no/mild periodontitis (p=0.023).Conclusions The findings from this pilot study suggest that future research is needed to determine whether sociodemographic and other general risk factors are more important contributors to periodontitis risk than CF-specific factors.

A conceptual model on caregivers' hesitancy of topical fluoride for their children.

BACKGROUND: Topical fluoride hesitancy is a well-documented and growing public health problem. Despite extensive evidence that topical fluoride is safe and prevents tooth decay, an increasing number of caregivers are hesitant about their children receiving topical fluoride, leading to challenges in clinical settings where caregivers refuse preventive care. PURPOSE: To explore the determinants of topical fluoride hesitancy for caregivers with dependent children. METHODS: In this qualitative study, we interviewed 56 fluoride-hesitant caregivers to develop an inductive conceptual model of reasons why caregivers are hesitant. RESULTS: The core construct of the conceptual model of topical fluoride hesitancy centered on caregivers "wanting to protect and not mess up their child". Six domains comprised this core construct: thinking topical fluoride is unnecessary, wanting to keep chemicals out of my child's body, thinking fluoride is harmful, thinking there is too much uncertainty about fluoride, feeling pressured to get topical fluoride, and feeling fluoride should be a choice. CONCLUSIONS: Topical fluoride hesitancy is complex and multifactorial. Study findings provide insight for future efforts to understand and optimize caregivers' preventive care decision making.

Silver diamine fluoride-associated delays in procedural sedation in young children: A retrospective cohort study.

BACKGROUND: This analysis evaluated the time to first sedation or general anesthesia (GA) encounter for children treated with and without silver diamine fluoride (SDF). METHODS: This retrospective cohort study used dental claims of privately insured children from birth through age 71 months with a sedation or GA claim from 2016 through 2020. The exposure was SDF use (yes, no). The outcome was time to first sedation or GA. Descriptive and multivariable negative binomial analysis was performed. The analysis tested the hypothesis that among children who received sedation or GA for their caries treatment, those who received SDF would show a longer time to first sedation or GA than children who did not. RESULTS: Among 175,824 children included, SDF use increased the time to first sedation or GA encounter by 63 days when treated by different dentists (405 days vs 342 days; P < .001) and by 91 days when treated by the same dentist (337 days vs 246 days; P < .001), after controlling for the effects of age at first encounter, sex, and region of the country. CONCLUSION: Children treated with SDF had a longer time to first sedation or GA, which was magnified when treatment was performed by the same dentist. PRACTICAL IMPLICATIONS: Within an individualized caries management plan, SDF could provide benefits for patients, dental offices, and health systems.

Introducing dental students to dental public health: An analysis of US predoctoral course syllabi.

Dental public health competencies in predoctoral dental education ensure that students have the skills to succeed in an increasingly complex professional environment. This study examined existing public health curricula in US dental education and their alignment with national recommendations from the American Association of Public Health Dentistry (AAPHD) and guidance from the Healthy People Curriculum Task Force for health professions education programs. We contacted all US dental schools (N = 66) in November 2020-January 202 and requested syllabi for schools' first course with dental public health content. We received 34 syllabi, which provided textual data for content analysis. The authors used an initial content analysis tool to extract descriptive course characteristics. Then, direct and emergent coding was performed to summarize course content. Direct codes included the 23 dental public health topics specified by AAPHD recommendations. Uncategorized content was coded using an inductive approach to identify emergent course themes. Frequently covered topics included principles of dental public health (79% of syllabi) and access to care (79%). "Health disparities" was the most common emergent theme, with 50% of courses including related content. There was little consistency in how courses approached each topic. For example, the topic "access to care" covered healthcare delivery systems, determinants of health, legislative reform, and advocacy. Dental public health was often taught alongside unrelated content. Recommendations for dental public health competencies should be updated to include new educational priorities, align with current national recommendations, and align with Commission on Dental Accreditation Standards more clearly.
