Validation of a Two-Item Food Security Screening Tool in a Dental Setting.

Purpose: The United States is typically viewed as a wealthy country, yet not all households have access to enough food for an active, healthy life. The purpose of this study was to validate a two-item written food security screen that health providers may use to identify food insecurity in their patient populations.Methods: Data were obtained from 150 parents or guardians who brought a child to a dental appointment at The Center for Pediatric Dentistry, University of Washington, Seattle, Wash., USA. The sensitivity and specificity of two written questions were determined by comparing with the United States Department of Agriculture Six-item Short Form of the Food Security Survey Module.Results: The sample consisted of 141 surveys after those with critical questions left blank were removed. The prevalence of food insecurity was found to be 31 percent at the Center for Pediatric Dentistry. The six-item screen identified 44 foodinsecure families with an affirmative response to two or more questions. Compared with the six-item screen, the two-item screen was found to have 95.4 percent sensitivity and 83.5 percent specificity.Conclusions: The two-item food security screen was found to be sensitive and reasonably specific, providing a quick and accurate method to identify food-insecure families.

Parent, Dentist, and Independent Rater Assessment of Child Distress During Preventive Dental Visits.

PURPOSE: Although typically not painful, preventive dental care can be distressing to young children. A greater understanding of how adults perceive child distress may enable clinicians to improve the patient/parent experience through alignment of values and facilitation of shared decision-making. The purpose of this study was to examine the association between parent, dentist, and independent observer (IO) ratings of child distress during preventive dental procedures. METHODS: Sixty-five children younger than three years were seen for preventive dental care at a university dental clinic. Parents, dentists, and an IO rated intensity of child distress during four phases of the dental visit: (1) pre-exam; (2) positioning; (3) prophylaxis/exam/fluoride; and (4) post-exam. RESULTS: The average age of the children was 24.4 months old (±7.2 SD). The prophylaxis/exam/fluoride phase was judged to be most distress inducing. Mean distress ratings for this phase were: 2.30 (parents); 2.47 (dentists); and 3.08 (IO), which was statistically significant (P=.04). The IO ratings were significantly different from parents (for three phases) and dentists (for one phase); no statistically significant differences were noted between parent and dentist ratings for any phase. CONCLUSIONS: There was a strong agreement between parents' and dentists' ratings of child distress during preventive dental procedures.

The Effect of a Unique Pacifier on Anterior Open Bite and Overjet in the Primary Dentition: A Pilot Study.

PURPOSES: Pacifiers are the most common device used by children to satisfy their sucking needs. Because of their design, reports of anterior open bite and increased overjet are common. The purposes of this pilot study were to measure the effects of a unique pacifier in toddlers who have existing open bites and increased overjets; and secondly to determine the feasibility of recruiting and retaining toddlers for a six-month study. METHODS: Toddlers with existing open bite and increased overjet currently using a conventional pacifier were recruited from a university pediatric dental clinic. Baseline information was obtained. Visual examination and intraoral measurements were obtained. The study pacifier was introduced to replace the existing pacifier. Follow-up data was collected at three and six months post-intervention. RESULTS: Eight of the 11 toddlers (73 percent) completed the study. Recruitment was challenging because of the inclusion criteria and transportation; retaining participants required numerous reminders to parents. There was a significant difference between initial and final open bite and overjet measurements. CONCLUSION: It is feasible to recruit and retain toddlers but it required significant staff interventions. There was a significant improvement in reducing existing open bite and overjet with the pacifier after six months.

Diagnostic biomarkers for oral and periodontal diseases.

This article provides an overview of periodontal disease diagnosis that uses clinical parameters and biomarkers of the disease process.This article discusses the use of biomarkers of disease that can be identified at the tissue, cellular, and molecular levels and that are measurable in oral fluids such as saliva and gingival crevicular fluid. Biomarkers identified from these biologic fluids include microbial, host response, and connective tissue-related molecules that can target specific pathways of local alveolar bone resorption. Future prospects for oral fluid-based diagnostics that use micro-array and microfluidic technologies are presented.

Pediatric Dentist Density and Preventive Care Utilization for Medicaid Children.

PURPOSE: The purpose of this study was to evaluate county-level pediatric dentist density and dental care utilization for Medicaid-enrolled children. METHODS: This was a cross-sectional analysis of 604,885 zero- to 17-year-olds enrolled in the Washington State Medicaid Program for 11-12 months in 2012. The relationship between county-level pediatric dentist density, defined as the number of pediatric dentists per 10,000 Medicaid-enrolled children, and preventive dental care utilization was evaluated using linear regression models. RESULTS: In 2012, 179 pediatric dentists practiced in 16 of the 39 counties in Washington. County-level pediatric dentist density varied from zero to 5.98 pediatric dentists per 10,000 Medicaid-enrolled children. County-level preventive dental care utilization ranged from 32 percent to 81 percent, with 62 percent of Medicaid-enrolled children utilizing preventive dental services. County-level density was significantly associated with county-level dental care utilization (Slope equals 1.67, 95 percent confidence interval equals 0.02, 3.32, P<.05). CONCLUSIONS: There is a significant relationship between pediatric dentist density and the proportion of Medicaid-enrolled children who utilize preventive dental care services. Policies aimed at improving pediatric oral health disparities should include strategies to increase the number of oral health care providers, including pediatric dentists, in geographic areas with large proportions of Medicaid-enrolled children.

Pharmacokinetics of fluoride in toddlers after application of 5% sodium fluoride dental varnish.

The prevalence of dental caries (tooth decay) among preschool children is increasing, driven partially by an earlier age of onset of carious lesions. The American Academy of Pediatrics recommends application of 5% sodium fluoride varnish at intervals increasing with caries risk status, as soon as teeth are present. However, the varnishes are marketed for treatment of tooth sensitivity and are regulated as medical devices rather than approved by the US Food and Drug Administration for prevention of dental caries (tooth decay). The objective of this research is to examine the safety of use in toddlers by characterizing the absorption and distribution profile of a currently marketed fluoride varnish. We measured urinary fluoride for 5 hours after application of fluoride varnish to teeth in 6 toddlers aged 12 to 15 months. Baseline levels were measured on a separate day. The urine was extracted from disposable diapers, measured by rapid diffusion, and extrapolated to plasma levels. The mean estimated plasma fluoride concentration was 13 µg/L (SD, 9 µg/L) during the baseline visit and 21 µg/L (SD, 8 µg/L) during the 5 hours after treatment. Mean estimated peak plasma fluoride after treatment was 57 µg/L (SD, 22 µg/L), and 20 µg/kg (SD, 4 µg/L) was retained on average. Retained fluoride was 253 times lower than the acute toxic dose of 5 mg/kg. Mean plasma fluoride after placement of varnish was within an SD of control levels. Occasional application of fluoride varnish following American Academy of Pediatrics guidance is safe for toddlers.

Correlates of root caries experience in middle-aged and older adults in the Northwest Practice-based REsearch Collaborative in Evidence-based DENTistry research network.

BACKGROUND: The authors examined the correlates of root caries experience for middle-aged adults (aged 45-64 years) and older adults (65 years and older) to test the hypothesis that the factors related to root caries are different for middle-aged adults than they are for older adults. METHODS: The authors conducted an observational cross-sectional study that focused on adult patients aged 45 to 97 years recruited from the Northwest Practice-based REsearch Collaborative in Evidence-based DENTistry research network (N = 775). The outcome variable was any root caries experience (no/yes). The authors hypothesized that sociodemographic, intra- oral and behavioral factors were root caries correlates. The authors used Poisson regression models to generate overall and age-stratified prevalence ratios (PRs) of root caries, and they used generalized estimating equations to account for practice-level clustering of participants. RESULTS: A total of 19.6 percent of adults had any root caries. A dentist's assessment that the patient was at high risk of developing any caries was associated with greater prevalence of root caries experience in both middle-aged adults (PR, 2.70; 95 percent confidence interval [CI], 1.63-4.46) and older adults (PR, 1.87; 95 percent CI, 1.19-2.95). The following factors were associated significantly with increased root caries prevalence but only for middle-aged adults: male sex (P = .02), self-reported dry mouth (P < .001), exposed roots (P = .03) and increased frequency of eating or drinking between meals (P = .03). No other covariates were related to root caries experience for older adults. CONCLUSIONS: Within a practice-based research network, the factors associated with root caries experience were different for middle-aged adults than they were for older adults. Research is needed to identify relevant root caries correlates for adults 65 years and older. Practical Implications. Interventions aimed at preventing root caries are likely to be different for middle-aged adults than for older adults. Dentists should use root caries prevention programs that address appropriate aged-based risk factors.

Trimodal detection of early childhood caries using laser light scanning and fluorescence spectroscopy: clinical prototype.

There is currently a need for a safe and effective way to detect and diagnose early stages of childhood caries. A multimodal optical clinical prototype for diagnosing caries demineralization in vivo has been developed. The device can be used to quickly image and screen for any signs of demineralized enamel by obtaining high-resolution and high-contrast surface images using a 405-nm laser as the illumination source, as well as obtaining autofluorescence and bacterial fluorescence images. When a suspicious region of demineralization is located, the device also performs dual laser fluorescence spectroscopy using 405- and 532-nm laser excitation. An autofluorescence ratio of the two excitation lasers is computed and used to quantitatively diagnose enamel health. The device was tested on five patients in vivo as well as on 28 extracted teeth with clinically diagnosed carious lesions. The device was able to provide detailed images that highlighted the lesions identified by the clinicians. The autofluorescence spectroscopic ratios obtained from the extracted teeth successfully quantitatively discriminated between sound and demineralized enamel.
