County-level correlates of dental service utilization for low income pregnant women. Ecologic study of the North Carolina Medicaid for Pregnant Women (MPW) program.

BACKGROUND: Dental care utilization for low income pregnant women is met with challenges in the traditional dentist-centered model of care. County-level measures provide insights for policy and roles for stakeholders that extend beyond the dentist-patient relationship. We examined county-level data to generate hypotheses about factors that influence utilization of dental services in North Carolina's Medicaid for Pregnant Women (MPW) program. METHODS: County-level Medicaid utilization data for dental services for 2014-2016 were pooled to get mean county estimates of dental utilization in the MPW program. Descriptive statistics and multivariate regression models of dental utilization and county-level measures are presented. Data used were collected by NC Child and the Robert Wood Johnson Foundation's County Health Rankings Reports. USDA Economic Research Service data were used to categorize counties in terms of Farming, Recreation, Persistent Poverty, and metro/non-metro status using Rural Urban Continuum Codes. RESULTS: Dental utilization ranged from 1-26% with a median of 8.5% across the 100 counties of North Carolina. Strong patterns linking utilization of dental services in the MPW program to contextual social measures of well-being emerged, specifically, increased reporting of child abuse and neglect, elevated infant mortality, poor quality of life, and worse ranking in years of potential life lost. Counties with persistent poverty had lower rates of dental utilization. CONCLUSIONS: Utilization of dental services in the MPW program is generally low. Patterns identify the potential for enhancing community-clinical linkages to improve birth outcomes and care coordination for pregnant women to enhance dental utilization in this population. Dental coverage in the Medicaid program in most states is administered separately from medical coverage. The separation of the funding mechanisms adds a further layer of complexity to care integration. Efforts to enhance dental care for pregnant women in the Medicaid program may benefit from policy that aligns incentives for care coordination within the community. Policy that extends the window of eligibility for dental benefits to 24 months after the birth of the child will help women complete the dental treatment that is needed. This also leverages the value of care coordination for community stakeholders from diverse child health sectors.

Association between periodontitis and spontaneous abortion: A case-control study.

BACKGROUND: Spontaneous abortion, or miscarriage, is a complication of pregnancy which can severely affect women both physically and psychologically. We investigated the associations of periodontitis and periodontopathic bacteria with spontaneous abortion. METHODS: We conducted a matched case-control study in two tertiary hospitals in Khon Kaen, Thailand. Cases were 85 women with spontaneous abortion at <20 weeks of gestation matched to 85 controls on age, gestational age, and hospital. Full-mouth periodontal examinations were performed. Periodontitis was defined as at least one site with probing depth ≥5 mm and clinical attachment level ≥2 mm at the same site. Subgingival plaque samples were collected to determine the levels of Porphyromonas gingivalis, Tannerella forsythia, and Fusobacterium nucleatum using real time polymerase chain reaction. RESULTS: The cases were significantly more likely to have periodontitis (50.6%) than the controls (21.2%; P = 0.007). Conditional logistic regression revealed a crude odds ratio (OR) of 4.1 for the association between periodontitis and spontaneous abortion (95% confidence interval [CI] = 1.9-8.9, P = 0.001). The OR decreased, but was still significant, after controlling for previous miscarriage (OR = 3.3, 95% CI = 1.4-7.8, P = 0.006). There was no significant association between the levels of periodontopathic bacteria and spontaneous abortion. Increased levels of P. gingivalis and F. nucleatum were associated with periodontitis in both case and control groups. Association between increased T. forsythia levels and periodontitis was observed only in the case women. CONCLUSIONS: Periodontitis was more common in women with spontaneous abortions as compared with matched controls. Levels of periodontopathic bacteria was not associated with spontaneous abortion in this population.

Microtensile Bond Strength Between Glass Ionomer Cement and Silver Diamine Fluoride-Treated Carious Primary Dentin.

Purpose: The study objectives were to investigate the effect of silver diamine fluoride (SDF) on the microtensile bond strength between glass ionomer cement and carious primary dentin and evaluate the mode of restoration failure. Methods: Forty carious primary molars were sectioned in half through the middle of the carious lesion and randomly allocated to test and control groups. The test specimens were treated with 38 percent SDF, and the control, deionized water. The samples were stored in artificial saliva for 14 days at 37 degrees Celsius, and the dentin surfaces were conditioned and restored with Fuji IX GP Extra. After 24 hours in artificial saliva, the specimens were prepared for microtensile bond strength testing and stressed in tension at one mm per minute until failure. Mean bond strengths were compared using the paired t test. The failure mode was assessed with a stereomicroscope under 40X magnification. Results: The mean microtensile strength for the test group was 7.4 MPa (SD=±5.1) and 6.3 (±4.6) for the control group (P>0.05). Most common failure mode was the mixed failure mode in both groups. Conclusion: Silver diamine fluoride does not adversely affect the bond strength between glass ionomer cement and carious primary dentin in vitro.

Periodontal treatment among mothers with mild to moderate periodontal disease and preterm birth: reanalysis of OPT trial data accounting for selective survival.

Background: The Obstetrics and Periodontal Therapy (OPT) study, a randomized controlled trial, reported no effect of periodontal treatment on preterm birth. Even though there were more spontaneous abortions or stillbirths in the control group, sensitivity analyses using conventional approaches did not change the results. The development of newer epidemiological methods to assess bias caused by the truncated outcome, and the availability of OPT study data in the public domain, allowed us to reanalyse these data. Methods: We used the survivor average causal effect (SACE), also known as the principal strata effect, to correct potential bias resulting from unequal survival of fetuses in the treatment and control arms of the OPT study. Results: The risks of preterm and spontaneous abortions or stillbirths were respectively 49/413 (11.86%) and 5/413 (1.21%) in the periodontal treatment group, and 52/410 (12.68%) and 14/410 (3.33%) respectively in the control group. The risk differences (%) comparing periodontal treatment and control groups were -0.82%: 95% confidence interval (CI) -5.30% to 3.67% for preterm birth, and -2.12%: 95% CI -4.14% to -0.11% for spontaneous abortions or stillbirths before correction. Risk differences for preterm birth comparing periodontal treatment and control groups increased in magnitude, reached statistical significance and showed a beneficial effect of periodontal treatment after correction for bias using SACE. Conclusions: Periodontal treatment provided to mothers with mild to moderate periodontal disease before 21 weeks of gestation may prevent preterm births.

Periodontitis, edentulism and glycemic control in patients with type 2 diabetes: a cross-sectional study.

OBJECTIVES: To compare the glycemic control in non-smoking patients with type 2 diabetes according to their periodontal and dental status. RESEARCH DESIGN AND METHODS: This cross-sectional study investigated patients previously diagnosed with type 2 diabetes and under antidiabetic medication. Clinical data and fasting blood glucose (FBG) levels were collected from medical and dental records. Patients were divided into three groups according to dental and periodontal diagnosis: no or mild periodontitis (NO/MILD, n=96), moderate or severe periodontitis (MOD/SEV, n=74) and edentulous (n=141). FBG levels were compared between groups. Logistic regression was also applied to estimate the OR of presenting hyperglycemia. RESULTS: Edentulous patients had significantly higher FBG levels of 155.7±70.9 (mean±SD mg/dL) than those in the MOD/SEV (136.6±33.8) and the NO/MILD (123.1±36.7) groups. Differences between the latter two groups were also significant. Edentulous patients had adjusted ORs of 4.53, 4.27 and 3.95 of having FBG≥126, ≥150 and ≥180 mg/dL, respectively, in comparison with NO/MILD group. The MOD/SEV group also presented significant odds of having FBG≥126 mg/dL (OR=2.66) and ≥150 mg/dL (OR=2.45) than the NO/MILD group. CONCLUSIONS: Patients in the MOD/SEV group had worse glycemic control than the ones in the NO/MILD group. However, edentulous patients presented higher glycemic levels than both dentate groups, and also presented with higher odds of having hyperglycemia.

Comparison of Real-Time Quantitative PCR with a Chairside Test for Streptococcus Mutans Assessment.

OBJECTIVE: To compare two methods for Streptococcus mutans detection and quantification in the human oral cavity: a chairside commercial test and a molecular-based real-time quantitative polymerase chain reaction (qPCR) method. METHODS: A total of 688 whole saliva samples were collected from 344 children aged 3 and 5 and their biological mothers. Caries status was examined using a World Health Organisation survey method. S. mutans levels were measured using the Dentocult SM Strip mutans test and scored as colony forming units per millilitre of saliva. Meanwhile, bacterial genomic DNA was extracted from the saliva, qPCR was performed with S. mutans species-specific primers, and absolute S. mutans DNA concentrations were obtained and scored as micrograms of DNA per millilitre of saliva. The two methods were compared for sensitivity, specificity, agreement and correlation with caries status. RESULTS: Significantly more participants tested positive for S. mutans by qPCR than in the chairside SM Strip test (82.4% vs 71.4%). When only the highest and lowest test scores were considered, the agreement between the two methods assessing S. mutans colonisation was 0.956. Children with high levels of S. mutans in their saliva were six to eight times more likely to develop dental caries at 5 years old. CONCLUSION: The study provides new evidence supporting the use of the chairside SM Strip test or the qPCR assay for the detection and quantification of S. mutans colonisation in saliva as the analytical approach of choice for caries risk assessment in clinical and epidemiological studies.

A novel staging system for caries severity in the primary dentition.

OBJECTIVES: Caries in the primary dentition (CIPD) has a high prevalence in U.S. children compared to other diseases, with substantial disparities among different population groups. Few reports correlate CIPD prevalence with clinical impairment of children's quality of life, such as tooth pain, speech delay or trauma to the child from operative restorations, which we collectively term morbidity. Likewise, current case definitions (ECC, S-ECC) and disease metrics (mean dmfs/dmft) are not helpful in assessing morbidity for individual or groups of children. We describe a construct to stage caries severity for children ages 0 -5, called "CIPD Levels." This metric is based on small interval age-group dmft scores, and has a direct link to current and predicted morbidity for the child. It is modeled after staging systems for medical diseases in which the various stages or levels are correlated with the probability of morbidity or mortality. METHODS: We created a matrix in which CIPD Levels 0-4 are assigned for dmft scores 0-7 depending on a child's age. CIPD Level-4 is the highest level, and frequently results in clinical adverse outcomes, including pain and extensive restorations. We next tested this matrix with data from a high-risk population. RESULTS: Among children with any cavitated caries at age <24 months, 82.8% reached the adverse outcomes threshold (CIPD Level-4) at age 36 months. For children with dmft = 0 at 24 months, 71.4% did not reach CIPD Level-4 at age 36 months. CONCLUSION: Our new metric is useful for quantifying disease burden from caries for high-risk children.

Nationwide 2.5-Year School-Based Public Health Intervention Program Designed to Reduce the Incidence of Caries in Children of Grenada.

UNLABELLED: This paper describes an innovative public health intervention, called 'Smile Grenada', targeting the oral health of children in Grenada utilizing the resources of a US dental school, several oral health care companies, local governmental and public health authorities, and Grenadian school personnel. METHODS: Preintervention visual/tactile caries examinations were collected from 1,092 schoolchildren (mean age 9.9 years, standard deviation, SD = 3.7) in 2010. The intervention included: (1) classroom-based toothbrushing with fluoridated toothpaste, (2) fluoride varnish applied by trained dental students, teachers and local providers 3 times a year and (3) glass ionomer sealants placed on first permanent molars in children aged 6-8 years. Postintervention data were collected in May, 2013 (n = 2,301, mean age 9.8 years, SD = 3.7). Decayed and demineralized surfaces were examined for the whole sample and decay/demineralization and sealant retention on 6-year molars were examined separately (ages 6-8 in 2013 cohort). RESULTS: The number of decayed/demineralized surfaces declined across all age groups. The average number of decayed surfaces dropped from 9 at baseline to just over 6 (F1, 3,393 = 69.8, p < 0.0001) and the average number of demineralized surfaces dropped from 6 to less than 2 (1.8 surfaces; F1, 3,393 = 819.0, p < 0.0001). For children aged 6-8 years, there were statistically significantly fewer decayed surfaces (t1, 2,086 = 12.40, p < 0.0001; mean baseline 0.93, SD = 1.75; mean follow-up 0.23, SD = 0.83) and demineralized surfaces (t1, 2,086 = 19.7, p < 0.0001; mean baseline 2.11, SD = 2.74; mean follow-up 0.50, SD = 0.97) on 6-year molars. The Smile Grenada program successfully demonstrated a locally sustainable model for improving oral health in children in a developing country.

Noxious family environments in relation to adult and childhood caries.

BACKGROUND: The authors tested hypotheses that more noxious family environments are associated with poorer adult and child oral health. METHODS: A community sample of married or cohabiting couples (N = 135) and their elementary school-aged children participated. Dental hygienists determined the number of decayed, missing and filled surfaces via oral examination. Subjective oral health impacts were measured by means of questionnaires completed by the parents and children. The parents completed questionnaires about interparental and parent-to-child physical aggression (for example, pushing) and emotional aggression (for example, derision), as well as harsh discipline. Observers rated the couples' hostile behavior in laboratory interactions. RESULTS: The extent of women's and men's caries experience was associated positively with their partners' levels of overall noxious behavior toward them. The extent of children's caries experience was associated positively with the level of their mothers' emotional aggression toward their partners. CONCLUSIONS: Noxious family environments may be implicated in compromised oral health. Future research that replicates and extends these findings can provide the foundation to translate them into preventive interventions. PRACTICAL IMPLICATIONS: Noxious family environments may help explain the limitations of routine oral health preventive strategies. Interprofessional strategies that also address the family environment ultimately may prove to be more effective than are single modality approaches.

Association between selected oral pathogens and gastric precancerous lesions.

We examined whether colonization of selected oral pathogens is associated with gastric precancerous lesions in a cross-sectional study. A total of 119 participants were included, of which 37 were cases of chronic atrophic gastritis, intestinal metaplasia, or dysplasia. An oral examination was performed to measure periodontal indices. Plaque and saliva samples were tested with real-time quantitative PCR for DNA levels of pathogens related to periodontal disease (Porphyromonas gingivalis, Tannerella forsythensis, Treponema denticola, Actinobacillus actinomycetemcomitans) and dental caries (Streptococcus mutans and S. sobrinus). There were no consistent associations between DNA levels of selected bacterial species and gastric precancerous lesions, although an elevated but non-significant odds ratio (OR) for gastric precancerous lesions was observed in relation to increasing colonization of A. actinomycetemcomitans (OR = 1.36 for one standard deviation increase, 95% Confidence Interval = 0.87-2.12), P. gingivalis (OR = 1.12, 0.67-1.88) and T. denticola (OR = 1.34, 0.83-2.12) measured in plaque. To assess the influence of specific long-term infection, stratified analyses by levels of periodontal indices were conducted. A. actinomycetemcomitans was significantly associated with gastric precancerous lesions (OR = 2.51, 1.13-5.56) among those with ≥ median of percent tooth sites with PD ≥ 3 mm, compared with no association among those below the median (OR = 0.86, 0.43-1.72). A significantly stronger relationship was observed between the cumulative bacterial burden score of periodontal disease-related pathogens and gastric precancerous lesions among those with higher versus lower levels of periodontal disease indices (p-values for interactions: 0.03-0.06). Among individuals with periodontal disease, high levels of colonization of periodontal pathogens are associated with an increased risk of gastric precancerous lesions.

Periodontitis and gestational diabetes mellitus in non-smoking females.

BACKGROUND: Chronic inflammation has been implicated in the pathogenesis of gestational diabetes mellitus (GDM). Periodontal disease is associated with increased levels of inflammatory mediators and may be a risk factor for GDM. The authors aimed to examine the association between periodontitis and GDM among non-smoking pregnant females. METHODS: This case-control study included 50 females who were diagnosed with GDM and 50 age- and hospital-matched females without diabetes in Khon Kaen, Thailand. Full-mouth periodontal examinations were performed during pregnancy by two calibrated dentists who were unaware of the case-control status. Periodontitis was defined as ≥1 site with probing depth (PD) ≥5 mm and clinical attachment level (CAL) ≥2 mm at the same site. Serum samples were collected to measure C-reactive protein (CRP), tumor necrosis factor-α, and interleukin-6 levels. Analyses were performed using conditional logistic regression. RESULTS: Fifty percent of the case females had periodontitis compared to 26% of the controls. Females with GDM had significantly higher mean PD and CAL, more sites with bleeding on probing, and increased levels of CRP compared to the controls. Periodontitis was significantly associated with GDM (odds ratio = 3.00, 95% confidence interval = 1.19 to 7.56). The association remained significant with additional adjustment for family history of diabetes, prepregnancy body mass index, and weight gain during pregnancy. CONCLUSIONS: The results suggest that periodontitis is associated with GDM. Therefore, clinicians should assess periodontal conditions of pregnant females.

Periodontal inflammatory conditions among gutka chewers and non-chewers with and without prediabetes.

BACKGROUND: It is known that gutka chewing jeopardizes periodontal health; however, severity of periodontal inflammation in gutka chewers with and without prediabetes remains unknown. The aim of this study is to investigate the association of periodontal inflammatory conditions with gutka chewing and prediabetes. METHODS: In this cross-sectional study, the effect of gutka use on periodontal health is investigated among 44 individuals with prediabetes and 44 without prediabetes. Demographic information regarding age, sex, duration of prediabetes, and gutka-chewing habits was collected using a questionnaire. Periodontal inflammatory conditions (plaque index [PI], bleeding on probing [BOP], probing depth [PD], marginal bone loss [MBL]) and fasting blood glucose levels (FBGLs) were recorded. Group differences in periodontal inflammatory parameters were tested using univariate and multivariable analyses (α ≤5%). RESULTS: Periodontal inflammatory parameters (PI, BOP, and PD) were significantly higher in individuals with prediabetes irrespective of gutka-chewing habit (P <0.05). Odds of periodontal inflammation in individuals with prediabetes were nine times higher than in healthy controls (95% confidence interval [CI] = 3.4 to 23.6). Gutka chewing alone, chewing among individuals with prediabetes, and chewing among healthy controls did not significantly increase the odds of periodontal inflammatory conditions. Individuals with prediabetes were significantly more likely to have periodontal inflammation than individuals without prediabetes even after controlling for sex and gutka chewing (odds ratio = 13.2; 95% CI = 4.3 to 40.7). CONCLUSION: In medically healthy individuals, periodontal inflammatory conditions are worse in gutka chewers compared to non-chewers; in patients with prediabetes, the severity of periodontal inflammation is governed by hyperglycemia when compared to habitual gutka usage.

Involvement of Ayurvedic practitioners in oral health care in the United States.

BACKGROUND: Ayurveda, an ancient medical science originating in India, also is practiced in the United States. The authors conducted a study primarily to explore the involvement of Ayurvedic practitioners in treating oral diseases. METHODS: Eighty-five practitioners participated in this cross-sectional survey. The authors obtained self-reported data on demographics of the practitioners, the general and oral health conditions they treated, and the treatment modalities used. They performed descriptive statistical and logistic regression analyses by using statistical software. RESULTS: Participants predominantly were female and white or non-Hispanic, as well as part-time practitioners. Their educational backgrounds ranged from a 5½-year bachelor's degree in Ayurveda to short-term training. Of the 60 respondents who answered the question about treating oral diseases, 25 (42 percent) reported that they did so. Conditions treated were related to oral malodor, gingival or periodontal disease and toothache. Ayurvedic treatments administered for these conditions primarily were preventive in nature. CONCLUSIONS: Ayurvedic practitioners in the United States treat a variety of oral diseases by using predominantly preventive traditional care. Ayurvedic practitioners of Asian origin and those who practiced for a longer duration were more likely to report that they treated oral diseases. Larger, population-based studies are needed to understand more fully the current role of Ayurvedic practitioners in oral health care. Ayurvedic treatment modalities aimed at oral diseases need to be evaluated through rigorous randomized controlled trials for safety and effectiveness. PRACTICE IMPLICATIONS: Patients with limited or no access to oral health care might seek Ayurvedic treatment, and those who have access to conventional oral health care might wish to complement it with Ayurvedic treatment. Practitioners can incorporate preventive Ayurvedic treatments, which are based mainly on natural products, into overall preventive care regimens, if proven safe and effective.

Evaluation of in-office dental unit waterline testing.

In-office dental unit waterline (DUWL) testing systems are commercially available for monitoring DUWL bacteria. The current study compared Aquasafe, Petrifilm, and Heterotrophic Plate Count Sampler (HPCS) with R2A plating methodology, considered the gold standard for enumerating heterotrophic bacteria in potable water. Samples were collected from 20 dental units. Heterotrophic bacterial counts of ≤500 CFUs/mL were used as the cut-off for assessing in-office testing compared to R2A laboratory plating. Validity was assessed using sensitivity and specificity, along with positive and negative predictive values. Results were also compared using concordance and kappa statistics. All in-office tests demonstrated 100% specificity and positive predictive values, while sensitivity and negative predictive values were low (Petrifilm, 57%/50%; HPCS, 50%/46%; Aquasafe, 21%/35%). Concordance and kappa values for agreement with R2A plating were as follows: Petrifilm 70% (κ = 0.44), HPCS 65% (κ = 0.38), and Aquasafe 45% (κ = 0.14). In-office DUWL testing with Aquasafe, Petrifilm, and HPCS agreed poorly with R2A plating methodology and is not valid or reliable as a means of accurately monitoring bacterial density in DUWL. These in-office test systems should not be used for assessing compliance with the ADA and CDC standard for acceptable heterotrophic bacterial counts in DUWLs (≤500 CFUs/mL).

Association between oral health and gastric precancerous lesions.

Although recent studies have suggested that tooth loss is positively related to the risk of gastric non-cardia cancer, the underlying oral health conditions potentially responsible for the association remain unknown. We investigated whether clinical and behavioral measures of oral health are associated with the risk of gastric precancerous lesions. We conducted a cross-sectional study of 131 patients undergoing upper gastrointestinal endoscopy. Cases were defined as those with gastric precancerous lesions including intestinal metaplasia or chronic atrophic gastritis on the basis of standard biopsy review. A validated structured questionnaire was administered to obtain information on oral health behaviors. A comprehensive clinical oral health examination was performed on a subset of 91 patients to evaluate for periodontal disease and dental caries experience. A total of 41 (31%) cases of gastric precancerous lesions were identified. Compared with non-cases, cases were significantly more likely to not floss their teeth [odds ratio (OR) = 2.89, 95% confidence interval (CI): 1.09-7.64], adjusting for age, sex, race, body mass index, smoking status, educational attainment and Helicobacter pylori status in serum. Among participants who completed the oral examination, cases (n = 28) were more likely to have a higher percentage of sites with gingival bleeding than non-cases [OR = 2.63, 95% CI: 1.37-5.05 for a standard deviation increase in bleeding sites (equivalent to 19.7%)], independent of potential confounders. Our findings demonstrate that specific oral health conditions and behaviors such as gingival bleeding and tooth flossing are associated with gastric precancerous lesions.

Tooth decay in alcohol abusers compared to alcohol and drug abusers.

Alcohol and drug abuse are detrimental to general and oral health. Though we know the effects of these harmful habits on oral mucosa, their independent and combined effect on the dental caries experience is unknown and worthy of investigation. We compared 363 "alcohol only" abusers to 300 "alcohol and drug" abusers to test the hypothesis that various components of their dental caries experience are significantly different due to plausible sociobiological explanations. After controlling for the potential confounders, we observe that the "alcohol and drug" group had a 38% higher risk of having decayed teeth compared to the "alcohol only" group (P < .05). As expected, those who belonged to a higher social class (OR = 1.98; 95% CI = 1.43-2.75) and drank wine (OR = 1.85; 95% CI = 1.16-2.96) had a higher risk of having more filled teeth. We conclude that the risk of tooth decay among "alcohol only" abusers is significantly lower compared to "alcohol and drug" abusers.

"Does periodontal therapy reduce the risk for systemic diseases?".

Periodontal disease is treated by various approaches, including simple oral hygiene practices, professional mechanical debridement, antimicrobial therapy and periodontal surgery. There is evidence to associate periodontal disease with several systemic diseases and conditions, including myocardial infarction, adverse pregnancy outcomes, diabetes mellitus, and respiratory disease. This article reviews the published literature that describes the effects of periodontal treatment on cardiovascular diseases, adverse pregnancy outcomes, diabetes mellitus, and respiratory disease. While some progress has been made, further research is required to understand the value of periodontal interventions in the prevention of systemic diseases.
