Predictors of survival of large non-occlusal non-incisal glass-ionomer restorations in older adults.

PURPOSE: This study aimed to investigate the predictors of survival of non-occlusal non-incisal glass-ionomer restorations as a surrogate for root surface restorations among older adults. METHODS: In a retrospective cohort analysis using the University of Iowa College of Dentistry electronic dental records, we included 721 patients aged 65+ who received 2+ surface non-occlusal non-incisal glass ionomer restorations placed from January 2005 - December 2011. Restorations were followed until September 2017 or until they were deemed to have failed. RESULTS: At baseline, participants' mean age was 77.6 ± 8.2 years, and 45.8% were females. Most patients were self-pay (65.2%). Most restorations were placed by residents and dental students (82.7%) and included only two surfaces (95.6%). About half (49.1%) failed during follow-up, with a median survival time of 3.7 years. The time ratio for lower incisors compared to other teeth was 0.6 (p = .006), for three-and-four-surface restorations compared to two was 0.7 (p = .007), for faculty as providers compared to residents and students was 1.4 (p = .039), and for the Geriatric & Special Needs Clinic compared to others was 0.8 (p = .013). Time ratios less than one indicate association with shorter durations for restorations, and time ratios greater than one indicate association with longer durations for restorations. CONCLUSION: Tooth type, number of restored surfaces, provider type, and clinic were all significant factors associated with survival of these restorations.

Using machine learning algorithms to investigate factors associated with complete edentulism among older adults in the United States.

AIMS: Edentulism is an incapacitating condition, and its prevalence is unequal among different population groups in the United States (US) despite its declining prevalence. This study aimed to investigate the current prevalence, apply Machine Learning (ML) Algorithms to investigate factors associated with complete tooth loss among older US adults, and compare the performance of the models. METHODS: The cross-sectional 2020 Behavioral Risk Factor Surveillance System (BRFSS) data was used to evaluate the prevalence and factors associated with edentulism. ML models were developed to identify factors associated with edentulism utilizing seven ML algorithms. The performance of these models was compared using the area under the receiver operating characteristic curve (AUC). RESULTS: An overall prevalence of 11.9% was reported. The AdaBoost algorithm (AUC = 84.9%) showed the best performance. Analysis showed that the last dental visit, educational attainment, smoking, difficulty walking, and general health status were among the top factors associated with complete edentulism. CONCLUSION: Findings from our study support the declining prevalence of complete edentulism in older adults in the US and show that it is possible to develop a high-performing ML model to investigate the most important factors associated with edentulism using nationally representative data.

Triad multisystem phenotype with high risk for developing temporomandibular disorders-characteristics and potential pathophysiology results from the Orofacial Pain: Prospective Evaluation and Risk Assessment dataset.

ABSTRACT: A multisystem phenotype with the Triad of bodily pain, psychological distress, and sleep disturbance was found to have high risk for developing initial onset of painful temporomandibular disorders (TMDs) in the multicenter Orofacial Pain: Prospective Evaluation and Risk Assessment dataset. In this study, we systemically examined phenotypic characteristics and explored potential pathophysiology in quantitative sensory testing and autonomic nervous system domains in this multisystem Triad phenotype. Secondary analysis was performed on 1199 non-Triad and 154 Triad TMD-free Orofacial Pain: Prospective Evaluation and Risk Assessment enrollees at baseline. Results indicated that before developing TMDs, the Triad phenotype demonstrated both orofacial and systemic signs and symptoms that can only be captured through multisystem assessment. In addition, we found significantly lower resting heart rate variability and higher resting heart rate in the Triad phenotype as compared with the non-Triad group. However, pain sensitivity measured by quantitative sensory testing was not different between groups. These findings highlight the importance of whole-person multisystem assessment at the stage before developing complex pain conditions, such as TMDs, and suggest that, in addition to a "tissue damage monitor," pain should be considered in a broader context, such as a component within a "distress monitoring system" at the whole-person level when multisystem issues copresent. Therefore, the presence or absence of multisystem issues may carry critical information when searching for disease mechanisms and developing mechanism-based intervention and prevention strategies for TMDs and related pain conditions. Cardiovascular autonomic function should be further researched when multisystem issues copresent before developing TMDs.

Development and validation of a nursing home mortality index to identify nursing home residents nearing the end of life in dental clinics.

BACKGROUND: Nursing home (NH) residents seek care at dental offices, yet many of them are at the end of life. The uncertain life expectancy further complicates the care of NH residents. This study aimed to develop and validate a Nursing Home Mortality Index (NHMI) to identify NH residents in the last year of life. METHODS: Logistic modeling was used to develop predictive models for death within 1 year after initial appointment by utilizing the new patient examination data and mortality data of 903 Minnesota NH residents. The final model was selected based on areas under the curve (AUC) and then validated using data from 586 Iowa NH residents. Based on the final model, the NHMI was developed with the estimated 1-year mortality for the low, medium and high risk group. RESULTS: One-year mortalities were 21% and 26% in the development and validation cohorts, respectively. Predictors included age, gender, communication capacity, physical mobility, congestive heart failure, peripheral vascular disease, cancer, cerebrovascular disease, chronic renal disease and liver disease. AUCs for the development and validation models were 0.73 and 0.68, respectively. For the validation cohort, the sensitivity and specificity were 0.79 and 0.53, respectively. The estimated 1-year mortality risks for three risk groups were 0%-10%, 11%-19%, and ≥20%, respectively CONCLUSION: The high mortality rate of NH residents following a dental exam highlighted a need to incorporate patients' prognoses in treatment planning along with normative needs and patients' preferences. The NHMI provides a practical way to guide treatment decisions for end-of-life NH residents.

Effect of Receiving Dental Treatment on mortality among nursing facility residents.

AIM: To assess the association between receipt of different types of dental procedures and mortality among nursing home residents. METHODS AND RESULTS: Between June 2006 and March 2008, 535 nursing home residents received a health screening assessment and were offered comprehensive dental care. Death certificate data were obtained in September 2013 and multivariable regression models were generated to assess the effect of dental procedures delivered after the screening assessment on mortality, adjusting for demographic and health-related covariates. Residents had a mean age of 85.2 years at baseline and approximately 30% were edentulous. About two-thirds received at least one dental procedure, and about 88% had died, between the screening date and the end of follow-up. Among dentate residents, after adjustment for relevant covariates, for each one-unit increase in the number of intervals during which they received at least one preventive dental procedure there was a 13% decrease in mortality (HR = 0.87, 95% CI = 0.78-0.98) at any given time, while for prosthetic dental procedures there was a 16% decrease in mortality (HR = 0.84, 95% CI = 0.72-0.97). Among edentulous residents, only prosthetic procedures were analyzed, and they were not significantly associated with mortality. CONCLUSION: Among dentate institutionalized elderly, receipt of preventive or prosthetic dental procedures was associated with decreased mortality.

Surgery start time and early implant failure: A case-control study.

OBJECTIVE: To evaluate the influence of surgery start time (SST) and other patient- and therapy-related variables on the risk for early implant failure (EIF) in an academic setting. MATERIAL AND METHODS: Data were extracted from the electronic health records of 61 patients who had at least one EIF and 140 age- and gender-matched, randomly selected, non-EIF controls. Bivariate and multivariable analyses were performed to identify relevant associations between EIF and different variables, such as SST. RESULTS: Incidence of EIF was not significantly associated with SST (HR: 1.9 for afternoon implant placement, 95% CI: 0.9-3.9; p = .105). Other factors that were associated with a significantly increased risk for EIF in a multivariable model were pre-placement ridge augmentation (HR: 7.5, 95% CI: 2.2-25.1; p = .001), intra-operative complications (HR: 5.9, 95% CI: 2.2-16.3; p < .001), simultaneous soft tissue grafting (HR: 5.03, 95% CI: 1.3-19.5; p = .020), simultaneous bone grafting (HR: 3.7, 95% CI: 1.6-8.8; p = .002), and placement with sedation (HR: 3.4, 95% CI: 1.5-7.5; p = .002). CONCLUSIONS: While SST was not associated with the occurrence of EIF in our cohort, other variables, such as ridge augmentation prior to implant placement, simultaneous bone or soft tissue grafting, intra-operative complications, implant placement with sedation, and number of implants in the oral cavity, were associated with an increased risk for this adverse event.

Chairside risk assessment for first-onset temporomandibular disorders: Result from the Orofacial Pain: Prospective Evaluation and Risk Assessment data set.

BACKGROUND: Temporomandibular disorders (TMD) risk assessment is difficult in general dentistry owing to the complexity of multifactorial risk contributions and the lack of standardized education. The authors explored a health history-based chairside risk assessment. METHODS: Secondary data analysis was performed on the Orofacial Pain: Prospective Evaluation and Risk Assessment data set. Potential demographic, systemic, and local risk contributors were conceptualized into 10 risk categories. Multivariate Cox proportional hazards modeling with backward selection was applied. Variables with P values < .05 were kept in each successive model. RESULTS: The analysis included data from 2,737 participants. The final model indicated that people with any psychological conditions, pain disorders, sleep disorders, or orofacial symptoms were at elevated risks of developing first-onset TMD. Results of post hoc analysis showed the coexistence of conditions from multiple body systems conferred greater risk of developing TMD. CONCLUSIONS: Coexisting conditions and symptoms from multiple body systems substantially increase the risk of developing TMD pain. Therefore, multisystem risk assessment and interprofessional collaborations are important for the prevention of TMD. PRACTICAL IMPLICATIONS: Dentists should include psychological conditions, pain disorders, sleep disorders, and orofacial symptoms when assessing patients' risk of developing TMD pain.

Factors associated with the counts of selected oral microorganisms in nursing home residents.

PURPOSE/AIM: To analyze potential factors associated with levels of selected oral pathogens, as well as total aerobic bacterial species, among nursing home residents. MATERIALS AND METHODS: Nursing home residents were divided into three groups (G1 included people with teeth but no dentures, G2 included people with teeth and dentures, and G3 included people with no teeth and with dentures). All participants had microbiological samples collected from their oral cavity and dentures. Counts of total aerobic bacterial species, Porphyromonas gingivalis, Fusobacterium nucleatum, Actinomyces viscosus, Aggregatibacter actinomycetemcomitans, and Candida albicans were compared among groups using the Wilcoxon rank sum test. A multivariate analysis was also performed to control other available covariates. RESULTS: Bivariate analysis revealed significant differences among the groups, and multivariate analysis showed that sex, the presence of natural teeth, denture wearing, oral hygiene indices, and systemic health conditions were associated with bacterial and Candida albicans log counts. CONCLUSIONS: Presence of natural teeth and denture wearing, as well as oral hygiene, sex and systemic health conditions were associated with bacterial and Candida albicans log counts among nursing home residents.

Structuring, reuse and analysis of electronic dental data using the Oral Health and Disease Ontology.

BACKGROUND: A key challenge for improving the quality of health care is to be able to use a common framework to work with patient information acquired in any of the health and life science disciplines. Patient information collected during dental care exposes many of the challenges that confront a wider scale approach. For example, to improve the quality of dental care, we must be able to collect and analyze data about dental procedures from multiple practices. However, a number of challenges make doing so difficult. First, dental electronic health record (EHR) information is often stored in complex relational databases that are poorly documented. Second, there is not a commonly accepted and implemented database schema for dental EHR systems. Third, integrative work that attempts to bridge dentistry and other settings in healthcare is made difficult by the disconnect between representations of medical information within dental and other disciplines' EHR systems. As dentistry increasingly concerns itself with the general health of a patient, for example in increased efforts to monitor heart health and systemic disease, the impact of this disconnect becomes more and more severe. To demonstrate how to address these problems, we have developed the open-source Oral Health and Disease Ontology (OHD) and our instance-based representation as a framework for dental and medical health care information. We envision a time when medical record systems use a common data back end that would make interoperating trivial and obviate the need for a dedicated messaging framework to move data between systems. The OHD is not yet complete. It includes enough to be useful and to demonstrate how it is constructed. We demonstrate its utility in an analysis of longevity of dental restorations. Our first narrow use case provides a prototype, and is intended demonstrate a prospective design for a principled data backend that can be used consistently and encompass both dental and medical information in a single framework. RESULTS: The OHD contains over 1900 classes and 59 relationships. Most of the classes and relationships were imported from existing OBO Foundry ontologies. Using the LSW2 (LISP Semantic Web) software library, we translated data from a dental practice's EHR system into a corresponding Web Ontology Language (OWL) representation based on the OHD framework. The OWL representation was then loaded into a triple store, and as a proof of concept, we addressed a question of clinical relevance - a survival analysis of the longevity of resin filling restorations. We provide queries using SPARQL and statistical analysis code in R to demonstrate how to perform clinical research using a framework such as the OHD, and we compare our results with previous studies. CONCLUSIONS: This proof-of-concept project translated data from a single practice. By using dental practice data, we demonstrate that the OHD and the instance-based approach are sufficient to represent data generated in real-world, routine clinical settings. While the OHD is applicable to integration of data from multiple practices with different dental EHR systems, we intend our work to be understood as a prospective design for EHR data storage that would simplify medical informatics. The system has well-understood semantics because of our use of BFO-based realist ontology and its representation in OWL. The data model is a well-defined web standard.

Predictors of having a dentist among older adults in Iowa.

OBJECTIVES: Oral health plays an important role in the general well-being of older adults, yet older adults experience unique barriers to dental care. In the United States, almost two-thirds of older adults are dentally uninsured - a reflection of the exclusion of dental benefits from Medicare. The aim of this study was to investigate potential predictors of having a dentist among older adults receiving services funded through the Iowa Department on Aging (IDA). METHODS: This was a cross-sectional analysis on a convenience sample (n = 2692) of adults age 65+ who completed a required survey to determine eligibility to receive services from the IDA. Data from questionnaires completed between March and December 2017 were used to generate multivariable logistic regression models that identified predictors of having a dentist. The dependent variable, having a dentist, was gathered by self-report in the survey. Explanatory variables eligible for inclusion in the models included demographic and geographic factors, indicators of access to dental care, and factors related to activities of daily living. RESULTS: Fewer than half (46.2%) of the respondents reported having a dentist. In the final regression model, individuals with dental insurance were more than twice as likely to have a dentist than those without insurance. Conversely, individuals with a tooth/mouth problem and who need help with housekeeping and with transportation were significantly less likely to have a dentist than their counterparts. CONCLUSIONS: These results align with known insurance-related barriers and identify certain activities of daily living that might influence older adults' ability to access care. The finding that individuals with oral health problems were less likely to have a dentist underscores the need to reduce barriers to care for this population.

Self-perceived oral health among institutionalized older adults in Taubate, Brazil.

PURPOSE/AIM: To assess self-perception of oral health among institutionalized older adults in Taubate, Brazil. METHOD AND MATERIALS: Demographics, oral, and systemic health data were collected from a sample of 89 institutionalized older adults. The Geriatric Oral Health Assessment Index (GOHAI) was applied to assess their self-perception of oral health. A linear regression model using GOHAI scores and considering age, BMI, gender, race, dry mouth, denture status, number of teeth, number of comorbid conditions, and number of medications as independent variables was generated. RESULTS: Fifty-five percent were male, with an average age of 75.9 years (±9.1), 43.8% identified as mixed race, and 42.7% as white. The average BMI was 23.9 (±3.8), the average number of comorbid condition was 1.8 (±1.4), and the average number of daily medications was 6.2 (±3.6). The average number of teeth was 3.9 (±7.4), and 57.3% of the participants reported dry mouth sensation; 8.9% presented oral lesions, with denture stomatitis as the most common oral lesion (5.6%). The average GOHAI score was 31.1 (±3.7). Regression analysis showed a negative correlation between BMI and GOHAI scores (P = .032, R2  = 7.2%). CONCLUSIONS: Self-perception of oral health was good and negatively correlated with BMI.

Survival analysis of caries incidence in African-American school-aged children.

OBJECTIVES: To conduct an assessment of time-dependent covariates related to dental caries of the permanent dentition among a low socioeconomic status, understudied cohort of children, incorporating time-dependent covariates through the application of extended Cox proportional hazards modeling. METHODS: This study modeled the time to first cavitated dental caries in permanent teeth among school-aged children and assessed factors associated with this event. A cohort of 98 low socioeconomic status African-American children with mean age of 5.85 years at baseline was recruited in Uniontown, Alabama and followed prospectively for 6 years. None of these children had dental caries on permanent teeth at baseline, and oral examinations were performed annually. Caries-free survival curves were generated to describe time to event (having first decayed, filled, or missing permanent surface). Bivariate and multivariable extended Cox hazards modeling was used to assess the relationships between time-dependent and time-independent covariates and time to event. RESULTS: Twenty-eight children (28.6 percent) had their first permanent tooth caries event during the 6-year follow-up. Multivariable results showed that greater consumption of water was associated with lower dental caries hazard, while previous primary tooth caries experience was associated with greater dental caries hazard after adjustment for frequency of consumptions of milk, added-sugar beverages, and 100 percent juice. CONCLUSIONS: There was a global/overall significant caries protective effect of water consumption during the school-age period of child development.

Anterior restoration longevity among nursing facility residents: a 30-year retrospective study.

AIM: To assess factors influencing anterior dental restoration longevity among the institutionalized elderly. METHODS: Among a sample of Eastern Iowa nursing facility dental patients, one anterior restoration placed from 1985 to 2014 was selected at random from each subject. Kaplan-Meier survival curves were generated, with restoration failures defined as subsequent restorative codes involving the same surface; endodontic procedures; or extractions. Bivariate and multivariable Cox proportional hazards modeling were performed. RESULTS: In multivariable analyses, the 1985 to 1999 cohort (n = 496) had longer restoration survival in in females < 75 years old versus males < 75 years old (P = 0.016), males ≥75 years old (P = 0.026) and females ≥75 years old (P = 0.030); one- versus three-surface restorations (P < 0.001); and restorations placed by faculty/residents versus pre-doctoral students (P = 0.009). The 2000 to 2014 cohort (n = 521) had longer restoration survival in females < 75 years old versus males ≥75 years old (P = 0.012) and females ≥75 years old (P = 0.019); residents who paid out-of-pocket versus those on Medicaid (P = 0.019); and composite resin versus glass ionomer cement restorations (P < 0.001). CONCLUSIONS: Knowing how long restorations last, and what factors affect their longevity, could improve treatment planning, informed consent, and communication with residents and caregivers, and also help inform practice guidelines for restorative care among the institutionalized elderly.

12-month Success of Cracked Teeth Treated with Orthograde Root Canal Treatment.

INTRODUCTION: Long-term studies examining the treatment outcomes of "cracked teeth" that received orthograde root canal treatment in the United States do not exist. The purpose of the present study was to examine the distribution and 1-year treatment outcomes of cracked teeth receiving orthograde root canal treatment in 1 private endodontic practice over a 25-year period. METHODS: A total of 3038 cracked teeth were initially examined, and data from 2086 unique patients were analyzed. Pulpal and periapical diagnoses, year of treatment, tooth type, restorative material, and number of restored surfaces at the time of examination were recorded for all patients. Periodontal probing depths were also recorded. The patients' age and sex were added retrospectively for all patients whose data were available. Univariate frequency distributions for all collected variables were evaluated. Bivariate associations were analyzed between explanatory variables and the success of the root canal therapy. RESULTS: Of the 2086 cracked teeth observed among unique patients, the most common were mandibular second molars (36%) followed by mandibular first molars (27%) and maxillary first molars (18%). Among the 363 teeth eligible for multivariable regression analysis, 296 (82%) were deemed successes after 1 year. There were no statistically significant differences in success based on pulpal diagnosis (irreversible pulpitis, 85%; necrosis, 80%; previously treated, 74%), patients' age, sex, year of treatment, tooth type, restorative material, or number of restored surfaces at the time of examination. The 3 factors most significant in bivariate analyses were pocket depth, distal marginal ridge crack, and periapical diagnosis, which were used to generate a prognostic index for success of orthograde root canal therapy in cracked teeth called the Iowa Staging Index. CONCLUSIONS: The results of this study suggest that cracked teeth that received root canal treatment can have prognoses at higher success rates than previously reported. The Iowa Staging Index may prove to be useful in clinical treatment decision making.

Mutans Streptococci and Dental Caries: A New Statistical Modeling Approach.

Survival analyses have been used to overcome some of the limitations encountered with other statistical analyses. Although extended Cox hazard modeling with time-dependent variables has been utilized in several medical studies, it has never been utilized in assessing the complex relationship between mutans streptococci (MS) acquisition (time-dependent covariate) and time to having dental caries (outcome). This study involved secondary analyses of data from a prospective study conducted at the University of Alabama at Birmingham. Low socioeconomic status, African-American preschool children from Perry County, AL, USA (n = 95) had dental examinations at age 1 year and annually thereafter until age 6 years by three calibrated dentists. Salivary MS tests were done at ages 1, 1.5, 2, 2.5, 3, and 4 years. The patterns of and relationship between initial MS detection (time-dependent covariate) and dental caries experience occurrence were assessed, using extended Cox hazard modeling. The median time without MS acquisition (50% of the children not having positive MS test) was 2 years. Approximately 79% of the children had positive salivary MS tests by the age of 4 years. The median caries experience survival (50% of the children not having dental caries) was 4 years. During the follow-up period, 65 of the children (68.4%) had their initial primary caries experience. Results of the extended Cox hazard modeling showed a significant overall/global relationship between initial caries experience event at any given time during the follow-up period and having a positive salivary MS test at any time during the follow-up period (hazard ratio = 2.25, 95% CI 1.06-4.75). In conclusion, the extended Cox modeling was used for the first time and its results showed a significant global/overall relationship between MS acquisition and dental caries. Further research using causal mediation analysis with survival data is necessary, where the mediator "presence of MS" is treated as a time-dependent variable.

Preventive dental care among Medicaid-enrolled senior adults: from community to nursing facility residence.

OBJECTIVE: The primary objective of this study was to determine whether the utilization rate of preventive oral health care services while senior adults were community-dwelling differed from the rate after those same senior adults were admitted to nursing facilities. A secondary objective was to evaluate other significant predictors of receipt of preventive oral health procedures after nursing facility entry. METHODS: Iowa Medicaid claims from 2007-2014 were accessed for adults who were 68+ years upon entry to a nursing facility and continuously enrolled in Medicaid for at least three years before and at least two years after admission (n = 874). Univariate, bivariate and multivariable analyses were conducted. RESULTS: During the five years that subjects were followed, 52.8% never received a dental exam and 75.9% never received a dental hygiene procedure. More Medicaid-enrolled senior adults received ≥1 preventive dental procedure in the two years while residing in a nursing facility compared to the three years before entry. In multivariable analyses, the strongest predictor of preventive oral health care utilization after entry was the receipt of preventive oral health services before entry (p < 0.01). CONCLUSIONS: The strongest predictor of receipt of dental procedures in the two years after nursing facility entry was the receipt of dental procedures in the three years before entry while community-dwelling. This underscores the importance of the senior adult establishing a source of dental care while community-dwelling.

Dental status as a predictor of mortality among nursing facility residents in eastern Iowa.

OBJECTIVE: This study aimed to evaluate dental status (ie, number of teeth and presence of removable dental prostheses) as a predictor of all-cause mortality among nursing facility residents. BACKGROUND: Edentulism has been associated with poorer health outcomes in geriatric populations. MATERIALS AND METHODS: Between March 2006 and June 2008, oral health screening examinations were completed for 584 residents of 10 nursing facilities in four eastern Iowa counties. In September 2013, demographic, general and oral health information was obtained from the screening forms and linked with Iowa state death certificate data. The study outcome (time to death) was defined as the number of days between the screening examination and death. Univariate and bivariate distributions were assessed, and multivariable Cox proportional hazards regression models were generated to arrive at factors associated with time to death. RESULTS: A total of 535 residents were eligible for data analysis. Age at screening ranged from 60-103 years (mean=85.2), 70% were female, and 33% were edentulous. By September 2013, 468 (87.5%) had died, with a median time to death among these individuals of 2.0 years. The final multivariable Cox model included data from 393 (73.4%) of the residents; statistically significant relationships were observed between time to death and dental status, age, sex, cooperativeness with care providers and renal disease. CONCLUSIONS: Dental status remained strongly associated with time to death even after controlling for other important demographic and health-related factors.

Dental Caries in High-risk, School-age African American Children in Alabama: A Six-year Prospective.

PURPOSE: The purpose of this study was to assess the prevalence and incidence of dental caries in school-age African American children who received semi-annual fluoride varnish applications. METHODS: A cohort of six-year-old high caries-risk African American children (n equals 98) was recruited in Uniontown, Ala., USA, and followed for six years. Oral examinations were done annually by three trained/calibrated dentists. Tooth surfaces with cavitated caries, teeth missing due to caries, and teeth with filled surfaces were recorded using World Health Organization criteria. Also, as part of the study, children received periodic oral health instruction, fluoride varnish applications, and referrals to dentists starting at baseline. RESULTS: The person-level prevalence of decayed, missing, and filled surfaces of primary and permanent teeth (dmfs/DMFS) was: 61.2 percent at mean age of 5.9 years old (n equals 98, mean dmfs/DMFS equals 11.6); 63.8 percent at 6.7 years old (n equals 80, mean dmfs/ DMFS equals 13.2); 70.6 percent at 7.8 years old (n equals 68, mean dmfs/DMFS equals 14.2); 65.7 percent at 8.8 years old (n equals 68, mean dmfs/DMFS equals 11.8); 55.6 percent at 9.7 years old (n equals 63, mean dmfs/DMFS equals 8.8); 40.3 percent at 10.7 years old (n equals 62, mean dmfs/DMFS equals 3.4); and 37.1 percent at 11.7 years old (n equals 62, mean dmfs/DMFS equals 2.3). The six-year person-level incidence of dmfs/DMFS was 32.3 percent (mean dmfs/DMFS equals 1.6) from 5.9 to 11.7 years old (N equals 62). CONCLUSIONS: In spite of the oral health education and fluoride varnish applications, there was substantial new dental caries in this high-risk sample. Additional studies evaluating risk factors for caries development are ongoing.

Dental care after an emergency department visit for dental problems among adults enrolled in Medicaid.

BACKGROUND: Dental emergency department (ED) visits are increasing nationally, but EDs provide only palliative care. The authors examine time to subsequent dentist visit within 6 months after the ED visit, as well as the effect of having a dentist visit in the prior year. METHODS: Using 2010-2012 Iowa Medicaid claims data, the authors identified adults with an index dental ED visit. The authors examined the claims data for a subsequent dentist visit within the next 6 months. The authors used Kaplan-Meier curves and log-rank tests for bivariate analyses. The authors included a dentist visit in the year before the index ED visit, subsequent ED visits, and sociodemographic characteristics in a Cox multivariable regression model. RESULTS: A total of 2,430 adults enrolled in Medicaid satisfied the study inclusion criteria. Within 6 months, 52.4% had a subsequent dentist visit, 12.0% lost Medicaid eligibility, and 35.6% did not have subsequent dentist visit. Bivariate and multivariable analyses revealed that nonwhites, those without a dentist visit in the prior year, and those with subsequent ED visits had a significantly lower rate of subsequent dentist visits. CONCLUSIONS: Almost one-half of adults with a dental ED visit did not visit a dentist in the next 6 months. Adults who did not visit a dentist in the past year and those with repeated ED visits may be living with unresolved dental problems that can affect their quality of life. PRACTICAL IMPLICATIONS: Adults without a dentist visit in the past year and those who visit ED repeatedly can be targeted by ED diversion programs because they are at higher risk of not receiving follow-up dental care.
