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.

Occlusal contact changes in patients treated with clear aligners: A retrospective evaluation using digital dental models.

INTRODUCTION: This study used digital intraoral scans to evaluate how clear aligner treatment affects occlusal contacts and to determine the influence of sex and age on contact changes. Results were compared with contact changes that occur during fixed appliance therapy. METHODS: Patients included in this study were treated in a University setting and private practice. Inclusion criteria were a Class I malocclusion treated nonextraction with clear aligners and the presence of pretreatment and posttreatment digital intraoral scans. Scans were imported into specialized software, and occlusal contacts were analyzed. The effects of age and sex on contact changes during clear aligner treatment were determined. Changes in occlusal contacts were compared with changes that occur during nonextraction treatment of patients with a Class I relationship using fixed edgewise appliances. RESULTS: A total of 45 clear aligner patients fit the eligibility criteria. Clear aligner treatment reduced the percentage of tight, near, and approximating contacts, whereas the percentage of open and no contacts increased. These changes in occlusal contacts were greater for the older age group studied. Genderinfluenced occlusal contact changes in the anterior dentition only where the decrease in near contacts and increase in open contacts were greater for males. These results for patients treated with clear aligners were similar to those for patients treated with fixed appliances; both treatment modalities reduced close occlusal contacts at the time active treatment was completed. CONCLUSIONS: These results indicated that when clear aligners or fixed appliances are used to treat a Class I malocclusion, the resulting occlusion immediately after debonding is not as "tight" as it was at pretreatment.

Efficacy of 38% silver diamine fluoride in reducing gingival inflammation and plaque accumulation in older adults living in retirement-homes: A randomized controlled pilot trial.

OBJECTIVES: Emerging from earlier case reports the potential benefits of 38 % silver diamine fluoride (SDF) in addressing pathogenic biofilms and mitigating gingival inflammation and enlargement have sparked interest. Our study aimed to evaluate the efficacy of 38 % SDF in reducing gingival inflammation and plaque accumulation in older adults living in retirement-homes. METHODS: This 7-week randomized, controlled, double-blinded pilot trial employed a parallel assignment design. The study enrolled older adults (aged ≥65) residing in retirement homes in Dallas County, ultimately comprising a cohort of 40 participants who were evenly divided into two arms. The experimental group received SDF treatment, whereas the comparator group received a placebo. Over three consecutive weeks, both groups had solutions applied to the facial surfaces of all their teeth once per week. The primary outcomes measured the change in Löe-Silness Gingival Index (GI) and Silness-Löe Plaque Index (PI) at 7 weeks following baseline treatment. Repeated measures ANOVA was utilized to assess changes over time within each group (n = 15 each). Post-hoc paired t-tests were conducted to compare changes between week 1 and each subsequent follow-up time point (weeks 3, 5, 7), supplemented with 95 % confidence intervals for change from week 1. RESULTS: In the SDF group, within-group comparisons demonstrated significant reductions (adjusted p < .05) in GI scores within 3 weeks (-.93±.37), as opposed to week 1 (1.90±.39). Between-group comparisons unveiled reductions in both mean GI (p < .05) and PI (p < .05), indicating less gingival inflammation and plaque accumulation in the SDF group at all time points, commencing at week 3. CONCLUSIONS: This study showed that 38 % SDF was effective in reducing gingival inflammation and plaque accumulation in older adults living in retirement-homes. CLINICAL SIGNIFICANCE: Oral health in older adults is a public health concern, especially for the medically compromised or those without traditional care. Our findings offer hope for enhancing oral health quality of life by introducing a cost-effective, compliance-free, noninvasive, and accessible therapeutic. TRIAL REGISTRATION: NCT03445286.(clinicaltrials.gov).

Association between crowding estimation and extraction recommendations in orthodontics.

INTRODUCTION: Little is known about how precisely orthodontists in the United States (US) assess crowding or at what range of crowding they recommend extraction. This study aimed to assess the relationship between estimated crowding in patients with a Class I relationship and extraction recommendation by orthodontists in the US. The secondary aims were to evaluate the accuracy and precision of clinician estimations and determine if clinician background traits play a role in extraction decision-making. METHODS: An electronic survey was prepared using 4 patients with a Class I relationship with anterior crowding selected from a University Orthodontics Clinic and was sent to approximately 10,400 subjects through Facebook and the American Association of Orthodontists Partners in Research program. RESULTS: From the 297 responses received, most clinicians recommended extraction once crowding reached 9-10 mm in either the maxilla or the mandible. The data from 2 patients suggest this decision was more strongly correlated with mandibular crowding. Clinician estimations varied widely but, on average, were precise within approximately 2 mm of objective measurements. There was a tendency to overestimate crowding, especially by Northeastern practitioners. Clinicians who reported routinely measuring crowding or who reported that they recommended extractions to >10% of their patients were 1.2-2.0 and 1.4-1.6 times more likely, respectively, to recommend extraction in the patients. CONCLUSIONS: Crowding estimation was highly subjective and varied widely among clinicians. Most clinicians recommended extraction once maxillary or mandibular crowding approximated 9-10 mm. Some clinician demographics were correlated with the precision and accuracy of estimations and the likelihood of extraction in the patients.

Effectiveness of silver diamine fluoride 38% on reduction of gingivitis in dogs: a randomized clinical trial.

Introduction: Periodontal disease is a ubiquitous disease in small animal veterinary medicine. Currently regular professional dental cleaning and daily tooth brushing are considered gold standards in the prevention of periodontal disease. Efforts to find a noninvasive, cost effective and easy to use preventative for periodontal disease are ongoing. The primary objective of this double-blind randomized clinical trial was to determine if a single application of silver diamine fluoride (SDF) 38% on the buccal surface of all teeth would reduce gingivitis within 3 months in dogs with stage two periodontal disease. Methods: Twenty-nine client-owned dogs 3-12 years old, 6-35 pounds were randomized 1:1 into active and placebo-control groups. Both groups underwent a baseline treatment and a three-month follow-up under general anesthesia. Gingival Index (GI), Plaque Index (PI), and Calculus Index (CI) were assessed and recorded at each event. Results: A single application of SDF 38% did not significantly lower GI relative to the control group. However, the GI score dropped significantly in both groups relative to baseline, with a 53% reduction in the average GI score for dogs that received SDF 38% treatment and a 44% reduction for dogs that received placebo treatment. There were no differences in PI or CI scores compared to control groups. Conclusion: Further research is needed to determine if a more frequent application or a longer study duration would yield a different outcome.

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.

Factors Contributing to Canine Impaction in Patients With Unilateral Cleft Lip and Palate Undergoing Alveolar Bone Grafts.

BACKGROUND: Patients with unilateral cleft lip and palate (UCLP) undergo alveolar bone grafting (ABG) to unite the bony segments before eruption of the maxillary permanent canine. PURPOSE: This study assessed the frequency of canine impaction after ABG in the UCLP patient population and identified associated demographic, anatomical, and operative factors. STUDY DESIGN, SETTING, SAMPLE: This retrospective cohort study included 257 patients with UCLP who received ABG surgery at a single craniofacial center. PREDICTOR VARIABLES: The variables were cleft characteristics, pre-ABG procedures, operative factors, and dental anomalies identified through electronic health records, radiographs, and intraoral photographs taken before ABG and at least 2 years after ABG. MAIN OUTCOME VARIABLE: The primary outcome variable was the presence of an impacted maxillary canine, defined as malposition of a fully developed canine following ABG with full eruption of the contralateral canine. ANALYSES: The t tests, χ2 tests, and logistic regression analysis were used to evaluate frequency of canine impaction and test for associations with the predictor variables. RESULTS: Of 257 patients, 56% were male with a mean age of 9.2 years at the time of ABG. The frequency of canine impaction was 27% (n = 69, 95% confidence interval 22 to 33%). Significant associations were found for: complete clefts (30 vs 12%, P = .017), hypodivergent facial patterns (low angle: 46%; high angle: 29 vs 22% normal angle, P = .042), females (adjusted odds ratio [aOR] = 2.1, P = .015), early grafting with less than 1/3 developed canine root (aOR = 3.36, P = .024), pregraft extraction of primary canine (aOR = 2.3, P = .009) and greater permanent canine angulation (odds ratio = 1.1, P < .0001). No significant associations with pregraft orthodontic expansion or regrafting were detected. CONCLUSION AND RELEVANCE: In this study, about one in four patients with UCLP had an impacted canine. Multiple factors including pregraft extraction of the primary canine and increased canine angulation were associated with impaction of the permanent canine.

In-fiber Bragg sensor measurements assess fluid effects on strain in the periodontal space of an ex-vivo swine incisor complex under mechanical loading.

The purpose of this study is to determine whether in-fiber Bragg grating (FBG) sensors detect changes within the periodontal ligament (PDL) of ex-vivo swine tooth-PDL-bone complex (TPBC) when manipulating fluid content. Recording strain will allow for a better understanding of the biomechanics of viscoelastic load transfer from the tooth to the PDL during chewing and/or orthodontic tooth movement, as well as replication of these dynamics in regenerated PDL tissues. FBG sensors placed within the PDL of swine incisor teeth were used to measure strain resulting from an intrusive load. Specimens were mounted in a custom platform within an MTS machine and a compressive load was applied at 0.3 mm/s to a depth of 0.5 mm and held for 10 s. Median peak strain and load and median absolute deviation (MAD) were compared: dry vs. saline (n = 19) with bias-corrected bootstrap 95% CI. Dry vs. saline conditions did not statistically differ (median peaks of 5µÎµ, 103-105 N) and recorded strains showed high repeatability (MAD of 0.82µÎµ, 0.72µÎµ, respectively). FBG sensors did not detect the fluid changes in this study, suggesting that the deformation of tissues in the PDL space collectively determine FBG strain in response to tooth loading. The repeatability of measurements demonstrates the potential for FBG sensors to assess the strain in the PDL space of an in vivo swine model.

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.

Feasibility and acceptability of home delivery of water for dental caries control in Latinx children-"Sediento por una Sonrisa," Thirsty for a Smile: Single-arm feasibility study.

Background: Outcomes of surgical treatments under general anesthesia for early childhood caries of young children from low-income groups are poor requiring retreatment within 2 years. Dietary sugar is an ideal intervention target given that it is the most prominent risk factor for dental caries and there is increasing evidence of successful interventions to reduce its intake. Our aim is to investigate the feasibility and acceptability of the Thirsty for a Smile intervention, designed to promote consumption of water in lieu of sugar sweetened beverages, among children who underwent surgery for early childhood caries and their caregivers, mostly from Latino heritage. Methods: A single-arm feasibility study was conducted in a dental practice from a community health center in eastern Washington State. Bottled water was delivered to the participants' homes and caregivers received patient-centered counseling for setting goals to increase children's water intake and reduce sugar sweetened beverages consumption. We assessed the feasibility and acceptability of the intervention and study procedures through participation rates, interviews and a questionnaire completed by the caregivers. Data was analyzed and themes and descriptive statistics presented. Results: Twenty-two dyads of caregivers and their children between 2 and 9 years old who recently had surgical treatment for early childhood dental caries were enrolled. All study assessments were completed by more than 90% of participants, except for the final 24-h dietary recall (73%). Dietary counseling, both in person and brief telephone calls, was highly acceptable to the caregivers, and they also reported their children enjoyed and used the water bottles. On a scale from 1 to 10, the average rating for the helpfulness of the dietary counseling component for changing child's drinking habits was 9.62 and for the water delivery component, 8.86. Conclusions: This study tested the feasibility of conducting a trial in a dental practice setting, and the acceptability among caregivers of young children who underwent surgery for early childhood caries. It demonstrated that the Thirsty for a Smile intervention and study processes were feasible and acceptable. The study provides useful information for implementation of a two-arm randomized controlled trial in this setting and may also benefit other researchers attempting to test similar interventions.

Secular trends in dental services provided by dental therapists and dentists in Southwest Alaska.

BACKGROUND: The goal of the study was to identify secular trends in dental service delivery between dental therapists and dentists in the Yukon-Kuskokwim Delta region of Southwest Alaska, the first area of the United States to authorize dental therapy practice. METHODS: Electronic health record transactions from the Yukon-Kuskokwim Health Corporation from 2006 through 2015 (n = 27,459) were analyzed. Five types of dental services were identified using Current Dental Terminology procedure codes: diagnostic, preventive, restorative, endodontic, and oral surgery. Main outcomes were percentages of services provided by dental therapists compared with dentists and population-level preventive oral health care. RESULTS: The overall number of diagnostic, preventive, and restorative services in the Yukon-Kuskokwim Delta increased. For diagnostic services, there was a 3.5% annual decrease observed for dentists and a 4.1% annual increase for dental therapists (P < .001). Similar trends were observed for restorative services. For preventive services, there was no change for dentists (P = .89) and a 4.8% annual increase for dental therapists (P < .001). Dental therapists were more likely than dentists to provide preventive care at the population level. CONCLUSIONS: Dental therapists have made substantial contributions to the delivery of dental services in Alaska Native communities, particularly for population-based preventive care. PRACTICAL IMPLICATIONS: The study's findings indicate that there is a role for dental therapy practice in addressing poor access to oral health care in underserved communities.

Home Delivery of Water for Caries Prevention in Latinx Children ("Sediento por una Sonrisa," Thirsty for a Smile): Protocol for a Single-Arm Feasibility Study.

BACKGROUND: Dental caries has significant public health implications afflicting young children. In addition to low social economic status, the most prominent risk factor for early childhood caries is sugar in the diet, particularly sugar-sweetened beverages. Dental treatment for caries in young children is commonly performed under general anesthesia and a significant proportion of children require repeated treatment. Interventions to reduce sugar-sweetened beverage consumption could lead to reduced rates of retreatment for dental caries in young children. OBJECTIVE: This protocol describes the rationale, design, and methods of the "Thirsty for a Smile" feasibility study. The aim of the study is to assess the feasibility, acceptability, and appropriateness of a dietary intervention promoting water consumption in lieu of sugar-sweetened beverages among young patients, mostly from Latino heritage. METHODS: This protocol describes a single-arm feasibility study. Twenty-one dyads of children and their caregivers will be recruited. Children between 2 and 9 years old who recently had treatment under general anesthesia for early childhood dental caries will be eligible to participate. The intervention has two components: (1) environmental, in which bottled water is delivered to participants' homes; and (2) behavioral, in which caregivers will receive patient-centered counseling to increase children's water intake and reduce sugar-sweetened beverages consumption. Dental caries and anthropometric data will be collected at examination during baseline and final visits. The primary outcome is feasibility and secondary outcomes are acceptability and appropriateness of the intervention. RESULTS: Funding has been obtained from the National Institute of Dental and Craniofacial Research and the University of Washington approved the study. The feasibility study was conducted from March to November 2019. CONCLUSIONS: This feasibility study will test the study processes prior to a two-arm randomized controlled trial to determine feasibility and acceptability of the intervention and study procedures. This study may provide useful information for other researchers attempting to test similar interventions. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR1-10.2196/37200.

Mediation of outcomes for cognitive behavioral therapy targeted to parents of children with Functional Abdominal Pain Disorders.

OBJECTIVE: There is a large body of evidence for the efficacy of Cognitive Behavioral Therapy (CBT) in treating Functional Abdominal Pain Disorders (FAPD) in children. In most CBT interventions for FAPD, parents participate together with their children. However, only one study to date has examined targeting parents alone for treatment. The aim of the current study was to examine mediators of a parent-only CBT treatment incorporating social learning (SLCBT) for FAPD in children. METHODS: We examined mediators of child outcomes in an existing randomized controlled trial (n = 316) of parent-only social learning CBT compared to an education condition. Hypothesized mediators (parental protectiveness, perceived threat of pain, catastrophizing) were assessed at 3 months post-treatment, and outcomes (parent ratings of disability, quality of life, school absences, and health care visits) were assessed at 6 months post-treatment. Mediation analyses were performed using Hayes' PROCESS macro. RESULTS: Pain catastrophizing significantly mediated treatment effects for all outcomes (B ranged from -1.65 to 2.22). Reduction in pain threat was a significant mediator for all outcomes (B ranged from -1.84 to 3.13) except school absences and health care visits. Decrease in parental protectiveness mediated effects on disability and missed school (B ranged from -1.47 to 1.34). Mediation effects did not differ by in-person or remote delivery of SLCBT. CONCLUSION: Changes in maladaptive parental thoughts and behaviors following parent-only SLCBT intervention appeared to mediate the effects of the intervention. Parental catastrophizing appears to be a particularly important target given that decreases in that variable mediated all outcomes.

Untreated dental disease and lung transplant waitlist evaluation time for individuals with cystic fibrosis.

AIMS: Dental clearance is typically part of the evaluation process prior to placement on the lung transplant waiting list. Individuals with cystic fibrosis (CF) are thought to be at low risk for dental disease. We hypothesized that individuals with CF in need of lung transplantation would have lower dental disease prevalence and shorter waitlist evaluation time than individuals with non-CF lung diseases. METHODS AND RESULTS: We conducted a retrospective study of individuals who received a lung transplant between 2011 and 2017 at the University of Washington (Seattle, WA, USA) (N = 280). Untreated dental disease was assessed by the individual's dentist. Waitlist evaluation time was defined as the time, in days, from the initial evaluation by a transplant pulmonologist to placement on the lung transplant waiting list. We used logistic and linear regression models for hypothesis testing. The prevalence of untreated dental disease did not differ by CF status (p = 0.99). There was no difference in waitlist evaluation time for transplant recipients by CF status (p = 0.78) or by dental disease status (p = 0.93). CONCLUSIONS: Our findings provide further evidence that individuals with CF are not at low risk for dental disease. Ensuring optimal oral health is important for all individuals with lung diseases.

The accuracy of laser fluorescence (DIAGNOdent) in assessing caries lesion activity on root surfaces, around crown margins, and in furcations in older adults.

The authors conducted a case series to assess accuracy of DIAGNOdent (DD) in assessment of activity of dental caries lesions in root surfaces and in furcations and at crown margins. The study was a prospective, single center case series. The patients were 123 adults (age ≥ 55 years). To be included, a patient needed to have at least one active root caries lesion. The study was conducted at the Roseman College of Dental Medicine in South Jordan, Utah, USA and at area nursing homes. Lesions were rinsed and dried with air, and DD readings were obtained. Lesions were then isolated and 38% silver diamine fluoride was applied repeatedly for two minutes with a microbrush. DD readings and treatments were repeated every six months. Mean DD values were significantly different between active (unarrested) and inactive (arrested) caries for all comparisons, p-value < 0.0001. The optimal cut-off values for DD were between 20 and 35 except optimal cut-offs were higher for furcation and crown margin surfaces, particularly in the posterior (optimal cut-offs 40-45). This study demonstrates DD is a potentially valuable tool for assessing lesion activity in root surfaces, at restoration margins, and in furcations.

Survey and electronic health record-based medication use agreement in children with cystic fibrosis: A retrospective cross-sectional study.

BACKGROUND: Medication use is important to collect accurately in medically complex patients in both clinical and research settings. AIM: We assessed patient-level agreement for medication use between self-reported survey and electronic health record (EHR) for children with cystic fibrosis (CF). METHODS: Our retrospective cross-sectional study focused on children with CF ages 6-20 years from Seattle Children's Hospital in Washington state, USA (N = 85). A self- or parent-reported survey included questions on current use of specific medications and antibiotic use in the past 2 months. We compared survey data with data abstracted from the individual's EHR and derived Cohen's Kappa statistics to estimate the level of agreement between the two methods. RESULTS: Self-reported medication use was generally higher in the survey than in the EHR. The level of agreement ranged from slight for probiotics (74.1% agreement; 95% confidence interval [CI]: 64.6%-83.6%; kappa: 0.07), pancreatic enzymes (80% agreement; 95% CI: 71.3%-88.7%; kappa: 0.12), and vitamin D (55.3% agreement; 95% CI: 44.5%-66.1%; kappa: 0.20) to moderate for chronic azithromycin (80% agreement; 95% CI: 7.13%-88.7%; kappa: 0.50), proton pump inhibitors (76.5% agreement; 95% CI: 67.3%-85.7%; kappa: 0.46), and oral antibiotics (70.6% agreement; 95% CI: 60.7%-80.5%; kappa: 0.42). CONCLUSION: There is considerable heterogeneity in level of agreement in medication use between self-reported survey and EHR data for children with CF. Standardized approaches are needed to improve the accuracy of medication data collected in clinical practice and research.

Silver diamine fluoride treatment of active root caries lesions in older adults: A case series.

OBJECTIVE: The authors conducted a case series to determine arrest of root surface caries lesions in older adults when teeth were treated topically with 38 % silver diamine fluoride (SDF). METHODS: The study was a prospective, single center case series. The patients were 62 older adults (age ≥55 years) who sought treatment at a dental school clinic. To be included, a patient needed to have at least one active root caries lesion. Lesions were rinsed and then dried with air, isolated, and then 38 % SDF was applied for two minutes with a microbrush. Treated lesions were re-evaluated at 2-3 weeks. Treatment was repeated every six months. Survival analysis methods for clustered data were used to estimate the caries lesion arrest probability over time separately for root surfaces and at crown margins. RESULTS: Fifty-five participants returned for follow-up (44 % female, mean age (SD) 79.8 (7.4)). The probability of a lesion arresting with treatment ranged from 82.9 to 91.6%. Arrest rates at 18 months were slightly higher in root surfaces than around crown margins, 91.6 % (95 % CI 69.1-97.1) versus 89.8 % (95 % CI 71.6-96.3). All furcal lesions (n = 7) were arrested by 6 months, 100 % (95 % CI 59-100). CONCLUSION AND CLINICAL SIGNIFICANCE: Repeated application of 38 % SDF at 6-month intervals was effective in arresting decay of root surface lesions and lesions around crowns in older adults. Study outcomes support SDF treatment for older adult patients who are frail and residing in nursing homes or dependent living facilities.

Prescription drug monitoring program use and utility by Washington State pharmacists: A mixed-methods study.

OBJECTIVES: To explore factors and situations that influence pharmacists to use the prescription drug monitoring program (PDMP) and to characterize actions taken by pharmacists after alarming scenarios from a PDMP query. DESIGN: Explanatory sequential 2-phase mixed-methods design: (1) cross-sectional Web-based survey of Washington State pharmacists followed by (2) interviews with purposefully selected respondents to explore statistically significant quantitative findings. SETTING AND PARTICIPANTS: The study was conducted in Washington State from September 2018 to February 2019. A total of 967 Washington State pharmacists from various practice settings, including inpatient and outpatient pharmacies, participated. Ten outpatient pharmacists were interviewed in the second phase. OUTCOME MEASURES: The pharmacists reported the frequency of PDMP use, opinion on the usefulness of PDMP, and action(s) taken after a concerning PDMP report. RESULTS: The usable response rate for pharmacists with a PDMP account was 17.6% (818/4659), and usable response rate for all pharmacists was 10.4% (967/9263). PDMP use varied by race, practice setting, and employer policy on PDMP use. Among the 818 PDMP users, 396 (48%) used the database at least once during a shift. Frequent PDMP users were more likely to recommend naloxone compared with less frequent users (adjusted odds ratio 1.70 [95% CI 1.09-2.65], P = 0.02). The following 3 interview themes were identified: time, company policy, and red flags. CONCLUSION: PDMP has value to pharmacists of all practice settings studied. Frequent PDMP use may facilitate more pharmacist interventions, such as a naloxone prescription.

Evaluating Child Toothbrushing Behavior Changes Associated with a Mobile Game App: A Single Arm Pre/Post Pilot Study.

Purpose: The purpose of this pilot study was to evaluate changes in toothbrushing behaviors associated with a mobile game app. Methods: Thirty-four five- to six-year-olds were taught to use the Brush UpTM game app and played it once per day at home for seven days. The primary outcome was toothbrushing quality measured as duration and distribution. The paired t test was used to assess pre/post changes and Holm's method adjusted for multiple testing (α equals 0.05). Results: The mean age was 73.7±6.6 months; 29.4 percent were female, and 47.1 percent were Caucasian. After seven days, toothbrushing duration increased significantly (P<0.001). Toothbrushing distribution improved with increased brushing of the lingual, maxillary occlusal, and posterior buccal surfaces. For 15 children who played the game for 14 days, even greater improvements in quality and distribution were observed. Improvements in toothbrushing did not persist one year later without further app use but there were noted changes that could be clinically meaningful. Conclusions: Mobile health game apps can potentially improve toothbrushing quality in children. Additional trials are needed to assess mobile toothbrushing game apps.
