Early orthodontic treatment as a means to increase access for children enrolled in Medicaid in Washington state

BACKGROUND: The authors assessed the likelihood that interceptive orthodontic Medicaid programs would increase access to care for Washington children. METHODS: The authors surveyed 210 Washington state orthodontists, including questions on demographics, attitudes toward early treatment, use of innovations and perceptions of Medicaid. Respondents were either Medicaid participants or nonparticipants. RESULTS: Fifty of 159 respondents were Medicaid participants. Most respondents perceived early orthodontic treatment as beneficial. Medicaid participants were more willing to participate in Medicaid early-treatment programs, had slightly fewer patients in the "other insurance" category, provided more discounted fees, received more Medicaid inquiries, practiced in rural areas with lower household incomes, reported feeling overworked and experienced fewer Medicaid problems. The principal problem reported with the Medicaid system was low fee reimbursement. CONCLUSIONS: Programs offering early orthodontic treatment could increase access. Important barriers would be low fees and unfamiliarity with Medicaid. PRACTICE IMPLICATIONS: Medicaid should design programs aimed at early treatment with reasonable reimbursement and an educational component.     

The effects of Medicaid expansions on dental services at federally qualified health centers

BackgroundFederally qualified health centers (FQHCs) have become safety-net providers of dental services for low-income patients. The authors examined the effects of the Patient Protection and Affordable Care Act Medicaid expansions, according to level of dental benefits, on the number of visits for dental services at FQHCs.MethodsThe authors used publicly available facility-level data on 1,400 FQHCs across the United States from the 2011 through 2019 Uniform Data System. The authors used an event-study difference-in-difference design to examine the effects of expanding Medicaid in 2014, according to the level of dental benefits, compared with nonexpansion states. Outcomes included the number of dental visits for any dental service and separately for preventive and other services. Regression models adjusted for the demographic characteristics of the FQHC's patient population, county-level factors, and center and year fixed effects.ResultsExpanding Medicaid with extensive dental benefits has increased the number of dental visits provided at FQHCs in 2014 through 2019 from 2013 by 1,329 to 7,647 visits per FQHC on average compared with FQHCs in nonexpansion states. There was an increase in visits for both preventive and other dental services. In contrast, there was no evidence of such an increase from expanding Medicaid with limited or emergency-only dental benefits.ConclusionsExpanding Medicaid eligibility with extensive dental benefits has increased the number of dental visits at FQHCs, including for both preventive and other dental services.Practical ImplicationsAs safety-net providers, FQHCs might be able to provide more oral health care for low-income patients after Medicaid expansions that offer extensive dental benefits.     

Development of a conceptual model of oral health for malocclusion patients

Objectives:To provide an empirical test of the applicability of Locker''s conceptual model of oral health for malocclusion patients, and to suggest alternative models of the effect of malocclusion on well-being.Materials and Methods:Data from a survey of 323 adolescents attending for orthodontic treatment were analyzed to develop a new oral health model for malocclusion patients. Oral health–related quality of life (OHRQoL) was measured using the 14-item Oral Health Impact Profile; malocclusion was measured using the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN). Using structural equation modeling, the relationship between conceptual domains in Locker''s model was explored and three models of their interrelationship tested for goodness of fit.Results:Fit indexes for Locker''s model indicated that it did not fit the data well. Therefore, a modified model was developed to incorporate additional paths between other levels to better fit the data. The best fit was provided by a model in which the direct effects of malocclusion on pain, discomfort, and handicapping—and the direct effect of pain on disability—were removed. A direct effect of functional limitation on disability was allowed. The modified Oral Health Impact Profile model proved to be a good fit to the data (root mean square error of approximation  =  0.069).Conclusion:The pathways identified in Locker''s (1988) conceptual model of oral health may not be appropriate for describing the relationships between OHRQoL constructs in individuals with malocclusion. An alternative model is proposed.     

Increasing the Value of Orthodontic Research Through the Use of Dental Patient-Reported Outcomes

Ten years ago, Chalmers and Glasziou pointed out in the Lancet that 85% of all biomedical research was being avoidably wasted because of imbalanced research question/outcome selection, as well as poor study design, execution, and reporting. According to findings of recent “research on research” studies, a high level of such kind of avoidable waste should also exist in orthodontic research. This warrants efforts to improve each stage of the research production and reporting process.Nowadays, patients' psychosocial function is considered a core element of oral health. Also, their treatment needs and preferences have formed a main component of evidence-based dentistry. Therefore, to achieve shared decision-making, orthodontists need to have an adequate understanding of each patient's values and perceptions.In this context, orthodontic research should be patient-centered so that the knowledge and perception gaps between clinicians and patients can be reduced, and research evidence that is suitable for patients to understand can be provided. In addition, patient-centered outcomes that can reflect patients' perceptions and psychosocial status should be widely used.However, recent scoping reviews have shown that during the past decade, patient-centered outcomes including those regarding adverse effects, health service resource utilization, and quality of life have remained under-represented in orthodontic trials. Thus, the use of dental patient-reported outcomes and dental patient-reported outcome measures should be promoted to facilitate the provision of a patient-centered evidence base, reduce the avoidable waste related to research question/outcome selection, and thereby increase the value of orthodontic research.     

Medicaid adult dental benefits and oral health of low-income older adults

BackgroundOlder adults are keeping their natural teeth longer, spurring calls for dental coverage under Medicare. Although Medicare dental coverage would benefit all older adults, the poorest among them are already eligible for dental benefits through Medicaid. The authors examine the association between states’ Medicaid adult dental benefits and dental care use and tooth loss among low-income older adults.MethodsUsing the Behavioral Risk Factor Surveillance System data from 2014, 2016, and 2018, the authors examined adults 65 years or older. The outcomes examined included annual dental visit and partial and complete tooth loss. Poisson regressions were used to obtain risk ratios after adjusting for covariates.ResultsStates’ Medicaid adult dental benefits were significantly associated with dental care use, with low-income older adults in states with no coverage having the lowest probability of visiting a dentist (risk ratio [RR], 0.83; 95% CI, 0.74 to 0.94), followed by emergency-only coverage (RR, 0.91; 95% CI, 0.84 to 0.98) and limited benefits (RR, 0.91; 95% CI, 0.85 to 0.98) relative to states with extensive benefits. There were no significant differences in either partial or complete tooth loss.ConclusionsStates’ Medicaid adult dental benefits are significantly associated with dental visits among low-income seniors. Providing comprehensive dental benefits under Medicaid can improve access to dental care among low-income older adults.Practical ImplicationsAs the older adult patient population grows, the poorest older adults may face barriers to dental care in the absence of dental coverage. Dental professionals must engage in advocating for comprehensive dental coverage, especially for vulnerable populations.     

Assessing Patterns of Restorative and Preventive Care Among Children Enrolled in Medicaid,by Type of Dental Care Provider

BackgroundThe authors investigate the relationship of preventive dental treatment to subsequent receipt of comprehensive treatment among Medicaid-enrolled children.MethodsThe authors analyzed Medicaid dental claims data for 50,485 children residing in Wayne County, Mich. The study sample included children aged 5 through 12 years in 2002 who had been enrolled in Medicaid for at least one month and had had at least one dental visit each year from 2002 through 2005. The authors assessed dental care utilization and treatment patterns cross-sectionally for each year and longitudinally.ResultsAmong the Medicaid-enrolled children in 2002, 42 percent had had one or more dental visits during the year. At least 20 percent of the children with a dental visit in 2002 were treated by providers who billed Medicaid exclusively for diagnostic and preventive (DP) services. Children treated by DP care providers were less likely to receive restorative and/or surgical services than were children who were treated by dentists who provided a comprehensive mix of dental services. The logistic model showed that children who visited a DP-care provider were about 2.5 times less likely to receive restorative or surgical treatments than were children who visited comprehensive-care providers. Older children and African-American children were less likely to receive restorative and surgical treatments from both types of providers.ConclusionsThe study results show that the type of provider is a significant determinant of whether children received comprehensive restorative and surgical services. The results suggest that current policies that support preventive care–only programs may achieve increased access to preventive care for Medicaid-enrolled children in Wayne County, but they do not provide access to adequate comprehensive dental care.     

Malocclusion,orthodontic treatment,and the Oral Health Impact Profile (OHIP-14): Systematic review and meta-analysis

Objective:To synthesize evidence on the impact of malocclusion and its associated treatment on people''s quality of life across studies that used the Oral Health Impact Profile (OHIP-14) questionnaire in the adult population.Materials and Methods:A systematic search of the English literature using Medline, PubMed, and EMBASE yielded 98 unique citations. Studies using OHIP-14 with individuals 15 years of age and older were included. After initial screening, 64 citations were excluded and another 9 were excluded after reading full text reports; the remaining 25 were included in the review. All studies were observational and used one of three study designs: 11 compared the same group before and after treatment (pre-post design), 10 compared groups with and without malocclusion (independent groups design) and four compared an orthodontically treated group with an independent group requiring treatment (treated-untreated groups design). Only three studies using the pre-post design and four using the independent groups design reported comparable OHIP-14 data and were combined in separate meta-analyses. Meta-analysis was carried out using metan command in Stata.Results:The standardized mean difference (SMD) in OHIP-14 total score was 1.29 (95% CI: 0.67 to 1.92) for the three studies using the pre-post design. Similarly, the SMD score was 0.84 (95% CI: 0.25 to 1.43) for the four studies using the independent groups design. There was evidence of high heterogeneity and publication bias among the studies included.Conclusions:This meta-analysis revealed that OHIP-14 scores were significantly lower after receiving treatment for malocclusion and in individuals without malocclusion/orthodontic treatment need compared to those with such condition (independent groups).     

Pediatric patients' orthodontic treatment need, quality of life, and smiling patterns -- an analysis of patient, parent, and provider responses

Objectives: The objectives of this study is to explore the relationship between pediatric patients' orthodontic treatment need, the patients' assessments of their smile‐related quality of life (QoL), their parents' proxy assessment of their child's QoL and own assessments of their child's smile, and the patients' objectively assessed smiling patterns. Methods: Survey data were collected from 102 patients (53 boys/49 girls; age range: 9–13 years) and their parents. Orthodontic treatment need was assessed with the Index of Complexity, Outcome, and Need (ICON). Smiling patterns were determined by videotaping patients' smiles while they watched a cartoon. Thirty predetermined sections of these tapes were then assessed by two independent raters to measure the patients' smiling patterns. Results: The aesthetic component and total ICON scores correlated with the patients' smile‐related QoL (r = 0.25; P = 0.014/r = 0.23; P = 0.024), parental proxy assessments of the child's smile‐related QoL (r = 0.29; P = 0.004/r = 0.26; P = 0.009), the parents' own assessments of their child's smile (r = 0.32; P = 0.002/r = 0.29; P = 0.005), and the number of negative adjectives chosen by the parents to describe their child's smile (r = 0.32; P = 0.002/r = 0.30; P = 0.004). Although the smiling patterns were correlated with the patients' smile‐related QoL responses (height of smile: r = 0.29; P = 0.005/number of teeth shown: r = 0.30; P = 0.004), the ICON scores were not correlated with the patients' smiling patterns. Conclusions: Objectively assessed orthodontic treatment need correlates with the patients' and parents' assessments of the child's smile‐related QoL scores. However, while objective smiling patterns are related with the patients' smile‐related QoL, they are not correlated with the patients' orthodontic treatment need.     

Oral health and oral health care use among able-bodied adults enrolled in Medicaid in Kentucky after Medicaid expansion: A mixed methods study

BackgroundOral health care use remains low among adult Medicaid recipients, despite the Patient Protection and Affordable Care Act’s expansion increasing access to care in many states. It remains unclear the extent to which low use reflects either low demand for care or barriers to accessing care. The authors aimed to examine factors associated with low oral health care use among adults enrolled in Medicaid.MethodsThe authors conducted a survey from May through September 2018 among able-bodied (n = 9,363) Medicaid recipients who were aged 19 through 65 years and nondisabled childless adults in Kentucky. The survey included questions on perceived oral health care use. Semistructured interviews were also conducted from May through November 2018 among a subset of participants (n = 127).ResultsMore than one-third (37.8%) of respondents reported fair or poor oral health, compared with 26.2% who reported fair or poor physical health. Although 47.6% of respondents indicated needing oral health care in the past 6 months, only one-half of this group reported receiving all of the care they needed. Self-reported barriers included lack of coverage for needed services and lack of access to care (for example, low provider availability and transportation difficulties).ConclusionsLow rates of oral health care use can be attributed to a subset of the study population having low demand and another subset facing barriers to accessing care. Although Medicaid-covered services might be adequate for beneficiaries with good oral health, those with advanced dental diseases and a history of irregular care might benefit from coverage for more extensive restorative services.Practical ImplicationsThese results can inform dentists and policy makers about how to design effective interventions and policies to improve oral health care use and oral health outcomes.     

Impact of malocclusion on oral health–related quality of life in young adults

Objective:To assess oral health–related quality of life (OHRQoL) in young adult patients with malocclusion and to measure the association between orthodontic treatment need and OHRQoL.Materials and Methods:The study sample comprised 190 young adults aged 18 to 25 years who were attending orthodontic clinics at the Faculty of Dentistry. The Index of Orthodontic Treatment Need-Dental Health Component was used to measure orthodontic treatment need. Each participant was assessed for OHRQoL before and after treatment by using the Oral Health Impact Profile, Chinese version (OHIP-14).Results:Patients who had little or no, borderline, and actual need for orthodontic treatment represented 21.6%, 50.5%, and 27.9% of the total sample, respectively. OHRQoL (total OHIP-14 score and score for each domain) improved after treatment (P < .05). Significant differences in summary OHIP-14 scores were apparent with respect to orthodontic treatment need. Participants with high treatment need reported a significantly greater negative impact on the overall OHRQoL score. The greatest impact was seen in the psychological discomfort domain and the psychological disability domain.Conclusion:Malocclusion has a significant negative impact on OHRQoL. This is greatest for the psychological discomfort and psychological disability domains. The orthodontic treatment of malocclusion improves OHRQoL of patients.     

Dental care access among individuals with Down syndrome: a Malaysian scenario

Objective. The purpose of this cross-sectional study was to assess the legal representatives’ perceptions on dental care access of individuals with Down syndrome (DS) compared to their non-DS siblings in Peninsular Malaysia. Methods: This cross-sectional study was conducted throughout community-based rehabilitation centers (CBRC) and the Down Syndrome Organization. Legal representatives of individuals with DS within the criteria were given a structured and validated questionaire. Result. This study demonstrated that individuals with DS (76.9%) significantly utilized more health services than non-DS siblings (23.1%). The service most regularly used was speech therapy followed by opthalmology and dental services. Twenty-five per cent of respondents reported difficulty in finding dental care services for their DS child and 46.9% admitted that healthcare for their DS child took more time. The majority of DS individuals received less complex dental treatment and none received any orthodontic treatment, despite their severe occlusal problems. Conclusion. A high proportion of parents appear to be able to access dental and medical care for their DS child. However, some parents perceived difficulty in finding oral healthcare.     

Comparative analysis of dental procedure mix in public and private dental benefits programs

BackgroundThere is little published research on whether public and private dental benefits plans affect the types of oral health care procedures patients receive. This study compares the dental procedure mix by age group (children, working-age adults, older adults), dental benefits type (Medicaid and Children’s Health Insurance Program, private), and level of Medicaid dental benefits by state (emergency only, limited, extensive).MethodsThe authors extracted public dental benefits claims data from the 2018 Transformed Medicaid Statistical Information System. To compare procedure mix with beneficiaries who had private dental benefits, the authors used claims data from the 2018 IBM MarketScan dental database. The authors categorized dental procedures into specific service categories and calculated the share of procedures performed within each category. They analyzed procedure mix by age, plan type (fee-for-service, managed care), and adult Medicaid benefit level.ResultsAside from orthodontic services, the dental procedure mix among children with public and private benefits is similar. Among adults with public benefits, surgical interventions make up a higher share of dental procedures than routine preventive services.ConclusionsChildren with public benefits have a procedure mix comparable with those with private benefits. There are substantial differences in procedure mix between publicly and privately insured adults. Even in states that provide extensive dental benefits in Medicaid, those programs primarily finance invasive surgical treatment as opposed to preventive treatment.Practical ImplicationsThere is a need to assess best practices in publicly funded programs for children and translate those attributes to programs for adults for more equitable benefit design and care delivery across public and private insurers.     

Impact of Medicaid dental coverage expansion on self-reported tooth loss in low-income adults

BackgroundLow-income adults delay oral health care due to cost more than any other health care service. These delays lead to caries, periodontal disease, and tooth loss. Expanding Medicaid dental coverage has increased dental visits, but the potential impact on previously unmet oral health needs is not well understood.MethodsIn this analysis, the authors estimated the association between Medicaid dental expansion and tooth loss. Data on self-reported tooth loss among adults below 138% federal poverty guideline were obtained from the Behavioral Risk Factor Surveillance System. A difference-in-differences regression was estimated. Additional analyses stratified according to age and separated extensive and limited dental benefits.ResultsExpanding Medicaid dental coverage is associated with increased probability of total tooth loss of 1 percentage point in the total sample, representing a 20% relative increase from the pre-expansion rate. This increase was concentrated in states offering extensive dental benefits and was largest (2.5-percentage-point greater likelihood) among adults aged 55 through 64 years for whom both extensive and limited dental benefits were associated with total tooth loss.ConclusionsMedicaid expansion with extensive dental benefits was associated with increased total tooth loss among low-income adults. This finding suggests that greater access to oral health care addressed previously unmet oral health needs for this population.Practical ImplicationsAs public dental coverage continues to expand, dental care professionals may find themselves treating a greater number of patients with substantial, previously unmet, oral health needs. Additional research to understand the long-term effects of Medicaid dental insurance for adults on their oral health is needed.     

Perceptions of Dutch Orthodontic Patients and Their Parents on Oral Health-Related Quality of Life

Objective:To test the hypotheses that 1) there is no difference between orthodontic patients'' and their parents'' reports of patients'' oral health-related quality of life, and 2) there are no gender differences.Materials and Methods:The sample consisted of 182 orthodontic patients (age range, 8–15) and their parents. Respondents were required to complete the Child Oral Health Impact Profile (COHIP). Items were divided into five different subscales, and scores on all subscales were compared between and within groups. Also, scores on six additional items regarding treatment expectations and global health perception were compared. Two hypotheses were tested: first, that no differences between parents and patients would be detected, and second, that no differences between boys and girls would be found.Results:The first hypothesis could not be rejected. Only a few minor differences between parents and patients were found. The second hypothesis was rejected. Differences between boys and girls were found on the subscales Emotional Well-Being and Peer Interaction, indicating that girls experience more effects of oral health on their quality of life than do boys.Conclusions:Parents'' reports on their children''s oral health-related qualities of life were in agreement with reports of the orthodontic patients. This suggests that parents are suitable alternatives to their children in surveys measuring oral health-related quality of life.     

Maxillary Midline Diastema: a case report involving a combined orthodontic/maxillofacial approach

Abstract

This paper presents an orthodontic case of a large (14.5 mm) maxillary midline diastema that was related to the presence, and subsequent removal of 2 median maxillary supernumerary teeth and resulting bone loss. A combined orthodontic and maxillofacial approach involving bone grafting and fixed appliances was used to close the space. This episode of care was organized as interceptive treatment during development of the permanent dentition.     

Geographic distribution of specialist orthodontists and orthodontic providers in Japan

ObjectiveThis study aimed to clarify the geographic distribution of specialist orthodontists and dentists who provide orthodontic services in Japan.MethodsWe obtained data on the populations of 1750 municipalities in Japan in 2010 by referring to the census. We obtained data on the number of dentists who mainly provide orthodontic services (specialist orthodontists) and the number of dentists, including general dentists, who provide orthodontic services (orthodontic providers), by referring to the Survey of Physicians, Dentists, and Pharmacists. Furthermore, we referred to the directory on the website of the Japanese Orthodontic Society (JOS) to obtain data on JOS-qualified orthodontists. To assess the distribution of specialist orthodontists and orthodontic providers, we used Lorenz curves and Gini coefficients.ResultsThe median value for the number of specialist orthodontists and number of JOS-certified orthodontists per 100,000 persons aged between 5 and 40 years old was 0, while that of orthodontic providers was 27.5. Gini coefficients for specialist orthodontists and JOS-certified orthodontists were 0.523 and 0.615, respectively. On the other hand, the Gini coefficient for orthodontic providers was 0.258.ConclusionsRegional inequalities in the availability of specialist orthodontists are high, and medical access to specialist orthodontic services may be limited in areas other than urban districts. In municipalities with a population of fewer than 50,000 inhabitants, the number of specialist orthodontists was very low, but orthodontic providers were relatively evenly distributed. Our research results suggested that studying the distribution of specialist orthodontists and orthodontic providers can provide valuable information for developing dental care policies.     

A Comparison of Medical and Dental Outcomes for Medicaid-Insured and Uninsured Medicaid-eligible Children: A U.S. Population–Based Study

BackgroundIn a population-based study of Medicaid-eligible children, the authors described and compared sociodemographic attributes, medical and dental health care utilization, and health status between Medicaid-insured and uninsured Medicaid-eligible children.MethodsThe authors analyzed data from 2,491 poor Medicaid-eligible children 2 to 16 years of age who participated in the 1999–2004 National Health and Nutrition Examination Survey. They quantified the association of medical and dental health care utilization, health status and treatment needs with Medicaid insurance status by using multivariable logistic regression modeling, taking into account the complex survey design and sample weights.ResultsApproximately 40 percent of Medicaid-eligible children were uninsured. Medicaid-insured children were more likely to have an annual physician visit but no more or less likely to have good general or oral health, asthma or dental caries, or treatment needs than were uninsured Medicaid-eligible children. Medicaid-insured older children (9–16 years old) were more likely to have an annual dentist visit than were uninsured Medicaid-eligible older children.ConclusionsChildren with Medicaid coverage were more likely to use health care services but no more or less likely to have good general health, good oral health, asthma treatment needs or dental treatment needs.Practice ImplicationsTo improve health care use, more poor children need to be enrolled in Medicaid.
