Association between motor proficiency and oral health in people with intellectual disabilities.

BACKGROUND: People with intellectual disabilities (IDs) may be at increased risk of developing periodontal diseases and dental caries due to poor oral hygiene. Our aim was to investigate motor proficiency factors associated with presence of visible plaque and gingival bleeding in people with IDs. We were particularly interested in the level of dependence, manual coordination and fine manual control of people with ID, as well as the level of exhaustion of the primary caregiver. METHODS: In this cross-sectional study, 299 people with ID were evaluated for oral hygiene using the simplified Visible Plaque Index and for gum inflammation using the Gingival Bleeding Index. The Bruininks-Oseretsky Motor Proficiency Test assessed motor proficiency through fine manual control (fine motor integration and fine motor precision) and manual coordination (manual dexterity and upper limb coordination). The level of dependence was assessed by the Katz dependency index, and the caregiver was tested for exhaustion using the fatigue severity scale. Prevalence ratios [and 95% confidence intervals (CI)] were calculated using crude and adjusted Poisson regression with robust variance. RESULTS: The exhaustion of the caregiver was associated positively to visible plaque [prevalence ratio (PR) = 1.36; 95% CI 1.06-1.65]. For gingival bleeding, people with IDs that had better fine motor integration (PR = 0.49; 95% CI 0.33-0.75) and precision (PR = 0.50; 95% CI 0.26-0.94), as well as manual dexterity (PR = 0.62, 95% CI 0.49-0.77), presented better results. CONCLUSION: Poor oral hygiene and gum inflammation were associated with motor proficiency of people with IDs and caregivers' exhaustion. Interventions to improve the oral health of people with IDs should take into account such conditions.

Organizational Readiness to Implement System Changes in an Alaskan Tribal Dental Care Organization.

INTRODUCTION: Tribal health care systems are striving to implement internal changes to improve dental care access and delivery and reduce health inequities for American Indian and Alaska Native children. Within similar systems, organizational readiness to implement change has been associated with adoption of system-level changes and affected by organizational factors, including culture, resources, and structure. OBJECTIVES: The objectives of this study were to assess organizational readiness to implement changes related to delivery of evidence-based dental care within a tribal health care organization and determine workforce- and perceived work environment-related factors associated with readiness. METHODS: A 92-item questionnaire was completed online by 78 employees, including dental providers, dental assistants, and support staff (88% response rate). The questionnaire queried readiness for implementation (Organizational Readiness for Implementing Change), organizational context and resources, workforce issues, organizational functioning, and demographics. RESULTS: Average scores for the change commitment and change efficacy domains (readiness for implementation) were 3.93 (SD = .75) and 3.85 (SD = .80), respectively, where the maximum best score was 5. Perceived quality of management, a facet of organizational functioning, was the only significant predictor of readiness to implement change (B = .727, SE = .181, P < .0002) when all other variables were accounted for. CONCLUSION: Results suggest that when staff members (including dentists, dental therapists, hygienists, assistants, and support staff) from a tribal health care organization perceive management to be high quality, they are more supportive of organizational changes that promote evidence-based practices. Readiness-for-change scores indicate an organization capable of institutional adoption of new policies and procedures. In this case, use of more effective management strategies may be one of the changes most critical for enhancing institutional behaviors to improve population health and reduce health inequities. KNOWLEDGE TRANSFER STATEMENT: The results of this study can be used by clinicians and other leaders implementing changes within dental care organizations. To promote organizational readiness for change and, ultimately, more expedient and efficient adoption of system-level changes by stakeholders, consideration should be given to organizational functioning generally and quality of management practices specifically.

Randomized Trial Based on the Common-Sense Model of Self-regulation to Increase Child Dental Visits.

INTRODUCTION: School screening and the note home (pinned to a backpack) informing parents/caregivers that their child needs to see a dentist have not been effective. OBJECTIVES: The Family Access to a Dentist Study (FADS) evaluated the effectiveness of school interventions based on the common-sense model of self-regulation (CSM) among K-4 children needing restorative treatment. METHODS: FADS was a multisite double-blind randomized controlled trial with 5 arms. FADS tested a CSM-driven referral letter and dental information guide (DIG) to move caregivers from inaccurate to accurate perceptions of dental caries. Six school districts from Ohio and Washington (14 schools) participated in school years 2015 to 2016 and 2016 to 2017. A total of 611 caregivers were randomized, and 86% (n = 597 children) completed the exit examination. The primary outcome was receipt of care based on a change in oral health status determined clinically within 1 school year. RESULTS: In accordance with our primary aims, 5 arms were collapsed into 3: CSM letter and reduced CSM letter (combined), CSM letter + DIG and reduced CSM letter + reduced DIG (combined), and standard letter. Among all sites, 39.7% received restorative care (237 of 597). Combined analysis of sites revealed that the CSM referral letter (with and without the DIG) did not increase dental visits when compared with the standard letter. However, for combined sites (East Cleveland, Ohio; Washington), the CSM + DIG increased dental visits when compared with standard letter in univariate analysis (51.3% vs. 40.9%), indicating 1.6-times increased odds of a dental visit (95% CI, 0.97 to 2.58) after imputation and adjustment for covariates. The CSM + DIG group had 1.9-times increased odds (95% CI, 1.21 to 3.08) of care when compared the CSM letter alone. CONCLUSION: A CSM-driven approach to informing caregivers of the chronic nature of caries with resources in an illustrative manner can increase the benefit of school oral health screening (ClinicalTrials.gov NCT02395120). KNOWLEDGE TRANSFER STATEMENT: A school dental referral (note home) that tells a parent that the child has cavities has not been effective. In this trial, a referral based on the common-sense model of self-regulation increased follow-up care for children with restorative needs.

Added Sugar Consumption and Chronic Oral Disease Burden among Adolescents in Brazil.

Chronic oral diseases are rarely studied together, especially with an emphasis on their common risk factors. This study examined the association of added sugar consumption on "chronic oral disease burden" among adolescents, with consideration of obesity and systemic inflammation pathways through structural equation modeling. A cross-sectional study was conducted of a complex random sample of adolescent students enrolled at public schools in São Luís, Brazil ( n = 405). The outcome was chronic oral disease burden, a latent variable based on the presence of probing depth ≥4 mm, bleeding on probing, caries, and clinical consequences of untreated caries. The following hypotheses were tested: 1) caries and periodontal diseases among adolescents are correlated with each other; 2) added sugar consumption and obesity are associated with chronic oral disease burden; and 3) chronic oral disease burden is linked to systemic inflammation. Models were adjusted for socioeconomic status, added sugar consumption, oral hygiene behaviors, obesity, and serum levels of interleukin 6 (IL-6). All estimators of the latent variable chronic oral disease burden involved factor loadings ≥0.5 and P values <0.001, indicating good fit. Added sugar consumption (standardized coefficient [SC] = 0.212, P = 0.005), high IL-6 levels (SC = 0.130, P = 0.036), and low socioeconomic status (SC = -0.279, P = 0.001) were associated with increased chronic oral disease burden values. Obesity was associated with high IL-6 levels (SC = 0.232, P = 0.001). Visible plaque index was correlated with chronic oral disease burden (SC = 0.381, P < 0.001). Our finding that caries and periodontal diseases are associated with each other and with added sugar consumption, obesity, and systemic inflammation reinforces the guidance of the World Health Organization that any approach intended to prevent noncommunicable diseases should be directed toward common risk factors.

Risk factors for osteonecrosis of the jaws: a case-control study from the CONDOR Dental PBRN.

Case reports and cohort studies have linked bisphosphonate therapy and osteonecrosis of the jaws (ONJ), but neither causality nor specific risks for lesion development have been clearly established. We conducted a 1:3 case-control study with 3 dental practice-based research networks, using dentist questionnaires and patient interviews for collection of data on bisphosphonate therapy, demographics, co-morbidities, and dental and medical treatments. Multivariable logistic regression analyses tested associations between bisphosphonate use and other risk factors with ONJ. We enrolled 191 ONJ cases and 573 controls in 119 dental practices. Bisphosphonate use was strongly associated with ONJ (odds ratios [OR] 299.5 {95% CI 70.0-1282.7} for intravenous [IV] use and OR = 12.2 {4.3-35.0} for oral use). Risk markers included local suppuration (OR = 7.8 {1.8-34.1}), dental extraction (OR = 7.6 {2.4-24.7}), and radiation therapy (OR = 24.1 {4.9-118.4}). When cancer patients (n = 143) were excluded, bisphosphonate use (OR = 7.2 {2.1-24.7}), suppuration (OR = 11.9 {2.0-69.5}), and extractions (OR = 6.6 {1.6-26.6}) remained associated with ONJ. Higher risk of ONJ began within 2 years of bisphosphonate initiation and increased 4-fold after 2 years. Both IV and oral bisphosphonate use were strongly associated with ONJ. Duration of treatment >2 years; suppuration and dental extractions were independent risk factors for ONJ.

Dental risk factors for osteonecrosis of the jaws: a CONDOR case-control study.

BACKGROUND: Reports of osteonecrosis of the jaw (ONJ) have associated this lesion to treatment with bisphosphonates (BPs) and dental procedures. In this study, we investigated the association of specific dental diagnoses and procedures with ONJ among patients with past BP use. METHODS: Dentists from three practice-based research networks provided ONJ cases and controls (1:3). Data gathered from patients and dental offices with two respective standard questionnaires included demographic, medical, pharmaceutical, and dental information. Diagnoses and procedures up to 3 years prior to ONJ (prior to interview for controls) were analyzed within risk strata, defined by BP use and cancer status, using interaction terms within conditional logistic regression models. RESULTS: We enrolled 191 ONJ cases and 573 controls from 119 dental offices. Among participants who had used only oral BP, extraction was the only dental risk factor for ONJ (odds ratio (OR) = 12, p = 0.01). Suppuration was also more prevalent in cases (18 %) than in controls (9 %), but not statistically significant (OR = 9, p = 0.06). Among participants who had not used either oral or IV BP (a majority of whom received radiation therapy to the head and neck), suppuration was the only dental risk factor for ONJ (prevalence = 34 % for cases and 8 % for controls; OR = 7, p = 0.01). The prevalence of extractions in this group was also higher, but not statistically significant (44 vs 10 %; OR = 3). Limited power precludes definitive findings among participants exposed to IV BP. CONCLUSIONS: Among patients taking oral BP, extraction was the only dental procedure associated with subsequent ONJ development CLINICAL RELEVANCE: Results of this study suggest that routine dental procedures are not associated with development of ONJ in patients exposed to BPs.

Dentin hypersensitivity and oxalates: a systematic review.

Treatment of dentin hypersensitivity with oxalates is common, but oxalate efficacy remains unclear. Our objective was to systematically review clinical trials reporting an oxalate treatment compared with no treatment or placebo with a dentin hypersensitivity outcome. Risk-of-bias assessment and data extraction were performed independently by two reviewers. Standardized mean differences (SMD) were estimated by random-effects meta-analysis. Of 677 unique citations, 12 studies with high risk-of-bias were included. The summary SMD for 3% monohydrogen-monopotassium oxalate (n = 8 studies) was -0.71 [95% Confidence Interval: -1.48, 0.06]. Other treatments, including 30% dipotassium oxalate (n = 1), 30% dipotassium oxalate plus 3% monohydrogen monopotassium oxalate (n = 3), 6% monohydrogen monopotassium oxalate (n = 1), 6.8% ferric oxalate (n = 1), and oxalate-containing resin (n = 1), also were not statistically significantly different from placebo treatments. With the possible exception of 3% monohydrogen monopotassium oxalate, available evidence currently does not support the recommendation of dentin hypersensitivity treatment with oxalates.

Disparity between dental needs and dental treatment provided.

We hypothesized that more teeth would be treated by fee-for-service dentists than predicted by salaried dentists. In a cohort of 3818 participants, the number of teeth treated was related to the number of teeth with treatment needs by means of a zero-inflated negative binomial model. Among those obtaining dental care within 6 months (study population, n = 1239), the adjusted predicted number of teeth treated was 2 (95%CI = 1.7;2.3) for patients with no treatment needs. The sum of teeth treated by fee-for-service dentists (4374 when considering the whole cohort and 3550 when considering the study population) was much higher than that predicted by salaried dentists (4220 when considering the whole cohort and 1770 when considering the study population). Our findings demonstrate a disparity between dental needs assessment and the dental treatment actually provided.

Systemic antibiotics and tooth loss in periodontal disease.

Systemic antibiotics have been recommended for the treatment of destructive periodontal disease. Our goal was to relate antibiotic use for medical or dental reasons to subsequent tooth loss in a cohort of 12,631 persons with destructive periodontal disease. After adjustment for age, smoking, and other confounders, the dispensing of antibiotics for 1-13 days, 14-20 days, or 21 or more days was not associated with reduced tooth loss [Adjusted rate ratio (RR) = 1.0; 95% Confidence Interval (CI) = 0.8-1.1; RR = 1.2; 95% CI = 0.9-1.4, and RR =1.2, 95% CI =1.0-1.3, respectively]. Numerous subgroup analyses were consistent with these overall null findings, with two exceptions: Longer courses of tetracyclines were associated with reduced tooth loss among persons receiving periodontal care, and penicillin was associated with reduced tooth loss among persons with more severe disease. Long-term, larger randomized trials are needed to provide evidence that antibiotics reduce tooth loss when used in the management of destructive periodontal disease.

Oral health-related quality of life of periodontal patients.

BACKGROUND AND OBJECTIVE: The purpose of this study was to assess the oral health-related quality of life of patients presenting to a periodontal specialist by means of six questions, and to assess the perceived oral health by means of one question. Self-assessments of oral health were associated with clinical characteristics. MATERIAL AND METHODS: Logistic regression models were used to associate self-assessments with clinical characteristics in a cross-sectional study. RESULTS: On the six-item questionnaire, close to 20% (295/1480) of the patients reported that teeth, gums or dentures had an impact fairly often or very often on one or more items (eating, relaxing, avoiding going out, feeling self-conscious, pain or discomfort). On the single question requesting a self-assessment of oral health, 42% (628/1468) rated their oral health as fair or poor. Both common oral health-related quality of life problems and worse perceived oral health were associated with having more than eight teeth with>5 mm periodontal pockets (odds ratio=1.45, 95% confidence interval=1.01-2.08; and odds ratio=2.83, 95% confidence interval=2.08-3.84, respectively), compared with patients who had fewer than three teeth with>5 mm periodontal pockets. CONCLUSION: Oral health-related problems in patients presenting to a periodontal specialist office negatively affect their quality of life. If some of the findings of this study can be confirmed in other studies, it could change the perception of chronic periodontitis as a silent disease.

Secular trends in socio-economic disparities in edentulism: USA, 1972-2001.

For health care planning and policy, it is important to determine whether socio-economic disparities in edentulism, an ultimate marker of oral health, have improved over time. The aim of this study was to investigate the socio-economic disparities in edentulism between 1972 and 2001. Representative samples of the United States population, 25-74 years old, were obtained from NHANES I (1972), III (1991), and 1999-2002. Differences in the edentulism prevalence between high and low socio-economic positions (SEP) were compared. Differences in edentulism prevalence remained stable over approximately three decades (p = 0.480), being 10.6 percentage points in 1972, 12.1 percentage points in 1991, and 11.3 percentage points in 2001. Exploratory subgroup analyses suggested that disparities decreased for those individuals reporting a dental visit in the prior year and those reporting never having smoked. In conclusion, the absolute prevalence difference in edentulism between low and high socio-economic positions has remained unchanged over the last three decades.

Spurious associations in oral epidemiological research: the case of dental flossing and obesity.

BACKGROUND: Individuals with increased oral health awareness may also have increased general health awareness, and vice versa. Such associations between oral and general health awareness has the potential to induce spurious associations in oral epidemiological research. OBJECTIVE: To assess the extent to which oral self-care patterns and general health awareness are confounded, we investigated the association between flossing and obesity, two lifestyle factors that are unlikely to be causally related. METHODS: A cross-sectional study of 1497 individuals presenting for an initial periodontal exam by the specialist. Self-reported flossing behaviors and body mass index (BMI) categories were related using logistic regression models. RESULTS: After adjustment for confounding variables, lack of daily flossing was associated in a dose-dependent way with morbid obesity (odds ratio (OR), 20.3; 95% confidence interval (CI), 2.7-154.0), obesity (OR, 2.1; 95% CI, 1.5-2.9), and being overweight (OR, 1.7; 95% CI, 1.3-2.2). When restricting to never smokers, a significant relationship between obesity and lack of flossing remained. CONCLUSION: The strong associations between two causally unrelated oral and general lifestyle characteristics indicate that simplistic epidemiologic methodology is unlikely to provide insights into causal mechanisms of oral diseases or oral-systemic relationships.

Statin use and tooth loss in chronic periodontitis patients.

BACKGROUND: Statins have anti-inflammatory and bone stimulating properties that may positively affect chronic periodontitis. Our objective in this study was to evaluate whether statin use by chronic periodontitis patients had a beneficial impact on tooth loss. METHODS: In a retrospective cohort study (N patients = 1,021; mean follow-up = 7.1 years), dental records were merged with pharmacy data. Any statin use during 3 years, statin use during each of 3 consecutive years (regular use), and any statin use during the first 3 years after the initial periodontal exam were evaluated as predictors of tooth loss using negative binomial regression models with adjustment for potential confounding factors. RESULTS: Any statin use during 3 years was not associated with tooth loss rate in the year subsequent to the 3-year period (rate ratio [RR] = 1.00; 95% confidence interval [CI] = 0.56 to 1.81). Regular statin use during 3 years was associated with a non-significant 37% reduced tooth loss rate in the year subsequent to the 3-year period (RR = 0.63; 95% CI = 0.32 to 1.25). Any statin use during the first 3 years after the initial periodontal exam was associated with a 48% decreased tooth loss rate in year 4 and subsequent years (RR = 0.52; 95% CI = 0.29 to 0.95). CONCLUSIONS: Our findings were mixed for an association of statin use with reduced tooth loss in chronic periodontitis patients. Lack of control for some potential confounders, particularly smoking, and evaluation of different patterns of statin usage hamper the interpretation of the results. Exploration of these findings in additional epidemiological studies may be worthwhile.

Dental flossing and interproximal caries: a systematic review.

Our aim was to assess, systematically, the effect of flossing on interproximal caries risk. Six trials involving 808 subjects, ages 4 to 13 years, were identified. There were significant study-to-study differences and a moderate to large potential for bias. Professional flossing performed on school days for 1.7 years on predominantly primary teeth in children was associated with a 40% caries risk reduction (relative risk, 0.60; 95% confidence interval, 0.48-0.76; p-value, < 0.001). Both three-monthly professional flossing for 3 years (relative risk, 0.93; 95% confidence interval, 0.73-1.19; p-value, 0.32) and self-performed flossing in young adolescents for 2 years (relative risk, 1.01; 95% confidence interval, 0.85-1.20; p-value, 0.93) did not reduce caries risk. No flossing trials in adults or under unsupervised conditions could be identified. Professional flossing in children with low fluoride exposures is highly effective in reducing interproximal caries risk. These findings should be extrapolated to more typical floss-users with care, since self-flossing has failed to show an effect.
