The Effect of Marijuana-Smoking on Dental Caries Experience.

OBJECTIVE: This cross-sectional study aims to examine the effect of marijuana-smoking on dental caries experience and to explore the potential combined effects of tobacco and marijuana cigarette-smoking. METHODS: We used data from the 2011-2014 National Health and Nutrition Examination Survey (NHANES). We examined demographics, tobacco- and marijuana-smoking, dental examination, and dietary intake. Caries was measured as decayed, missing, filled teeth (DMFT). Data analysis included univariate, bivariate analyses, and linear regression model (LRM) to examine the association between marijuana-smoking and DMFT. RESULTS: Mean DMFT score was lowest for nonsmokers (8.72) and highest for current marijuana smokers (9.87) (P < .0001); however, LRM results revealed that marijuana-smoking was not associated with caries. Adjusted DMFT was the highest for current tobacco and former marijuana smokers (ß estimate = 1.18; 95% CI, -0.27 to 2.62), but the relationship was not statistically significant. CONCLUSIONS: After controlling for potential confounders, there was no significant association between marijuana-smoking and dental caries experience. However, when marijuana and tobacco were smoked concurrently, there was a notable increase in DMFT, although the difference was not statistically significant. Future research should be directed towards exploring the effects of different forms of marijuana consumption, such as edibles and drinkables, on caries development. Health promotion programmes should be aimed at educating the public regarding the combined health impacts of smoking both marijuana and tobacco, considering the potential heightened caries risk.

Depression and Differential Oral Health Status Among U.S. Adults With and Without Prior Active Duty Service in the U.S. Military, National Health and Nutrition Examination Survey 2011-2018.

INTRODUCTION: Veterans suffer from lower overall well-being than non-veterans because of their unique life course. This study aims to compare the impact of depression on oral health for veteran and non-veteran populations. MATERIALS AND METHODS: Data from 11,693 adults (18+) participating in the National Health and Nutrition Examination Survey (2011-2018) were analyzed. The outcome variables were dichotomous (at/above mean) decayed, missing, and filled teeth due to caries (DMFT), as well as the components, namely, missing teeth, filled teeth (FT), and decayed teeth (DT). The primary predictor variable combined depression screening outcome and veteran status (veteran/depressed, veteran/not depressed, non-veteran/depressed, and non-veteran/not depressed). Covariates included socioeconomic factors, demographics, wellness factors, and oral health-related habits. Associations between outcome and predictor variables were assessed with a fully adjusted logistic regression analysis. RESULTS: Veterans, regardless of depression status, had more DMFT, FT, missing teeth, and DT compared to non-veterans. After controlling for covariates, veterans suffering from depression had higher odds of DT (1.5, 95% CI, 1.0-2.4) compared to non-veterans without depression. In general, veterans who screened negative for depression had better oral health compared to all groups, with lower odds of DT (0.7, 95% CI, 0.6-0.9) and higher odds of FT (1.4, 95% CI, 1.1-1.7) compared to non-veterans with and without depression. CONCLUSIONS: This study found that not only veterans have higher odds of overall caries experience, but also veterans suffering from depression have higher odds of active caries compared to non-depressed veterans. Most veterans lack Veterans Health Administration dental benefits and face challenges maintaining oral health on top of medical and mental health burdens. Our results add further urgency to increasing dental care access for this vulnerable population because of the exacerbation of unmet oral health care needs attributable to the additional mental health challenges veterans face.

Oral health risk factors and overall dental treatment needs for incoming air force recruits.

OBJECTIVE: To determine if relationships exist between the total dental treatment needs of incoming Air Force recruits and non-clincal demographic and oral-health related factors. METHODS: Data from the 2018 Air Force Recruit Oral Health Study (ROHS) was used, an anonymized sample of 1330 AF recruits that included a comprehensive oral exam and survey collecting demographic and oral health behavior information. The primary outcome variable was the total number of dental treatment needs for recruits, and independent predictor variables included select socio-demographic factors and wellness behaviors. Along with descriptive statistics, a multivariable negative binomial regression analysis was performed to assess the relationship between variables with a normalized weight making the final results representative of all incoming recruits. RESULTS: The final adjusted analysis showed that an incoming recruit's self-rated oral health, dental coverage prior to enlistment, need for a dental visit within the last 12 months, sugar intake, and tobacco use increased their risk for dental treatment needs. CONCLUSION: This is the first study to assess the relationship between specific risk indicators and increased dental treatment needs while adjusting other related covariates. Factors associated with dental treatment needs were identified that provide Air Force leaders with actionable information to directly improve recruit oral health and military readiness by identifying new airmen at the highest risk for excessive dental care needs while at basic military training.

Response to commentary: See Original Article here.

This letter is a response to commentary by Dr. Smith on 'Examining the association between cancer history in early life and dental care utilization'. We provided additional information and clarification regarding our analysis and results in response to Dr. Smith's questions and comments. Despite the limitations and weaknesses of our study, we still believe that it provides important information and further research questions.

Examining the association between cancer history in early life and dental care utilization.

OBJECTIVES: This study aims to examine associations between cancer history in early life (diagnosed at 20 years of age or younger) and utilization of dental care. METHODS: We analysed data of 10,185 participants, aged ≥20 years, from the National Health and Nutrition Examination Survey cycles 2015-2018. The main predictor was self-reported past history of any type of cancer diagnosed at 20 years of age or younger (yes/no). The outcome variables were having a dental visit within the past year, treatment or preventative visit, urgent need for care, and unmet dental need. Covariates included gender, age, race, marital status, education, and income. Bivariate and multiple logistic regression were conducted, accounting for the complex sampling design. RESULTS: There was no difference between early life cancer survivors in regards to dental visit within the past year (OR: 0.7; 95% CI: 0.3-1.6), visit for dental treatment (OR: 0.6; 95% CI: 0.3-1.6), urgent need for care (OR: 0.8; 95% CI: 0.3-2.0), or unmet dental need (OR: 0.6; 95% CI: 0.2-1.6) compared to cancer-free participants. CONCLUSIONS: Cancer history in early life doesn't impact dental care visits, type of last dental visit, dental care recommendation, or unmet dental need. Future cohort studies are needed to confirm this association.

Association between Parity and Dental Caries Experience among US Women: Findings from the National Health and Nutrition Examination Survey.

AIM AND OBJECTIVE: This study aims to investigate the association between parity and dental caries among US women. MATERIALS AND METHODS: National Health and Nutrition Examination Survey (NHANES 2001-2004) data for parous women aged 20-45 years were used for our analysis (n = 1,914). The association between parity (number of pregnancies resulted in live births) and caries experience [the decayed, missing, and filling teeth (DMFT) index] was analyzed using bivariate and multivariate regression analyses. SAS software version 9.1 was used for the statistical analyses. We used survey procedures (e.g., SURVEYFREQ, SURVEYMEANS, and SURVEYREG) that incorporate information on the appropriate weights to account for NHANES's complex sampling design. RESULTS: The bivariate analysis showed a trend of increase in dental caries experience among parous women as the number of live births increased (p = 0.007). After adjusting for confounders, such as age, socioeconomic status (SES), dental care coverage, and utilization, a significant association was still observed between parity level and dental caries experience (p = 0.009). CONCLUSION: Our results suggest that higher parity can be associated with dental caries experience among US women of reproductive age. CLINICAL SIGNIFICANCE: Clinicians should be aware of this finding to promote better oral health care and education among women with increased parity.

The association between the supplemental nutrition assistance programme participation and dental caries among U.S. adults.

INTRODUCTION: The Supplemental Nutrition Assistance Programme (SNAP) is a federal programme aimed to alleviate hunger and improve food insecurity. The impact of SNAP participation on overall health has been studied. However, little is known about the effects of SNAP participation on oral health. We aimed to investigate the association between participating in SNAP and dental caries and to explore the role of food insecurity as a moderator in this relationship. METHODS: We obtained data from the National Health and Nutrition Examination Survey (NHANES) cycles 2011-2012 and 2013-2014.The primary outcome was untreated dental caries (none vs. one or more). Self-reported SNAP participation status in the past 12 months was the predictor, and food security was the moderator. Food security was measured as overall food security status (full food secure/ food insecure) and household-level food security (full, marginal, low and very low). Bivariate and multiple logistic regression analyses were conducted to evaluate the relationship between SNAP and dental caries, and whether food insecurity moderates this relationship. Statistical analysis was carried out in September 2020. RESULTS: Our results suggested that after adjusting for potential confounders, SNAP participants were more likely to have untreated dental caries than non-SNAP participants (odds ratio: 1.6; 95% CI: 1.2-2.0). Food security status did not alter the relationship between SNAP participation and untreated dental caries. CONCLUSIONS: Food security status did not alter the relationship between SNAP participation and untreated dental caries. SNAP participation was associated with untreated dental caries among U.S. adults, and this was not affected by their food security status.

Breastfeeding and Early Childhood Caries: Findings from the National Health and Nutrition Examination Survey, 2011 to 2018.

Purpose: Childhood caries is a highly prevalent disease that is intricately connected to diet and other social and behavioral factors. While it has been established that breastfeeding confers many health benefits for children, previous research found no consensus on the relationship between breastfeeding and caries. The purpose of this study was to examine the relationship between early childhood caries (ECC) and the length of time breastfeeding using the National Health and Nutrition Examination Survey (NHANES). Methods: Four cycles of NHANES (2011 to 2018) were analyzed, including 3,234 children ages two to five years. The association between breastfeeding duration and incidence of ECC and severe earlychildhood caries (S-ECC) was evaluated using logistic regression, adjusting for age, ethnicity, education, income, last dental visit, and sugar-sweetened beverages. Results: In the study population, 16.9 percent had ECC and 12.2 percent had S-ECC. Breastfeeding six months to one year, one to two years, or over two years was not associated with higher odds of ECC or S-ECC than breastfeeding for zero to six months after adjusting for covariates. Conclusions: There was no statistically significant relationship between breastfeeding and early childhood caries, and breastfeeding duration was not associated with increased caries risk. More research from well-controlled analytical studies is needed to establish or refute a relationship between breastfeeding and ECC.

The association between food insecurity, diet quality, and untreated caries among US children.

BACKGROUND: The aim of this study was to examine the association between food insecurity and untreated caries among US children and the potential role of diet quality as a mediator in this relationship. METHODS: The authors analyzed data for 4,822 children aged 5 through 17 years from the National Health and Nutrition Examination Survey cycles from 2011 through 2014. The authors measured food security as household-level food security status (full, marginal, low, very low) and overall food security status (full food secure, food insecure). They measured diet quality using the Healthy Eating Index. The primary outcome measure was untreated caries (none, ≥ 1). The authors used multiple logistic regression analysis to evaluate the relationships among food insecurity, diet quality, and untreated caries. They conducted mediation analysis using the Baron and Kenny approach. RESULTS: Food-insecure children were more likely to have untreated caries compared with their fully food-secure counterparts, after controlling for confounding variables (odds ratio [OR], 1.38; 95% [CI, 1.11 to 1.72). Specifically, children from marginal and very low food-secure households had significantly higher odds of untreated caries (OR, 1.48; 95% CI, 1.10 to 2.01) compared with children from fully food-secure households (OR, 1.59; 95% CI, 1.12 to 2.26). Diet quality was not significantly associated with untreated caries. CONCLUSIONS: Food insecurity was negatively associated with untreated caries among US children. Diet quality was not associated with untreated caries. PRACTICAL IMPLICATIONS: Social factors such as food insecurity should be taken into consideration when dental clinicians perform caries risk assessment because caries risk is shown to be associated with overall health and dental health.

The association between food insecurity and dental caries among U.S. adults: Data from the National Health and Nutrition Examination survey.

OBJECTIVES: The purpose of this study was to examine the association between food insecurity and untreated dental caries using a nationally representative sample of US adults. METHODS: Data from the National Health and Nutrition Examination Survey (NHANES) cycles 2011-2012 and 2013-2014 on adults aged 18 years and older were analysed (n = 10 723). Primary predictors were overall food security (food-secure/ food-insecure) and household food security (full, marginal, low and very low). The main outcome was any untreated dental caries (none/ ≥ one). Multiple logistic regression analyses were done to estimate the adjusted odds ratio after controlling for confounders. RESULTS: Food-insecure adults were more likely to have untreated dental caries than food-secure adults after adjusting for potential confounders (OR: 1.2; 95% CI: 0.9-1.5). Adults from households with marginal (OR:1.4; 95% CI:1.5-2.2), low (OR:1.3, 95% CI:1.3-2.0) and very low food security (OR:1.3; 95% CI:0.9-1.5) had higher odds of untreated caries than adults from households with full food security. Following age stratification, marginal, low and very low food-secure adults had higher prevalence of untreated dental caries than full food-secure adults across all age groups. CONCLUSIONS: Our findings suggest that food-insecure adults had higher odds of untreated dental caries than food-secure adults. These findings highlight the importance of assessing food insecurity as a risk factor for dental caries. Longitudinal cohort studies are recommended to determine causal mechanisms.

The effect of diet drinks on caries among US children: Cluster analysis.

BACKGROUND: The effect of sugared beverages on dental caries has been widely studied in dental literature. A major limitation of these studies was examining the beverages as a single source. To overcome this limitation, a few studies used cluster analysis to group people into similar beverage consumption patterns. These studies did not differentiate between sugared beverages and diet drinks. Therefore the aim of this study is to examine the effect of consuming diet drinks on dental caries among US children by using cluster analysis. METHODS: In this cross-sectional study, the authors analyzed the dietary data of children aged 3 through 10 years, using 2 24-hour recall interviews in the 2011-2014 National Health and Nutrition Examination Survey data. Cluster analysis has been used to overcome the limitations of examining the beverages as a single source. Clusters were identified based on the R2 statistic and the local peak of pseudo-F statistics. Survey procedure and sample weights were used to account for the complex National Health and Nutrition Examination Survey sampling design. RESULTS: Six beverage consumption clusters were identified: high soda, high 100% juice, high juice drinks, high diet drinks, high milk, and high water. Regression analysis showed that the high soda cluster had a tendency to increase caries risk (odds ratio [OR], 1.69, 95% confidence interval [CI], 0.9 to 3.1), while the high diet drinks cluster had neutral effect compared with the high water cluster (OR, 0.94, 95% CI, 0.5 to 1.8). CONCLUSIONS: The results of this study suggest that diet drinks have no adverse effect on teeth among US children. Additional well-designed longitudinal studies should be conducted to establish the effect of diet drinks on caries when consumed during childhood. PRACTICAL IMPLICATIONS: Although this study did not show an association between caries and diet drinks, dental practitioners should be cautious about recommending these drinks, as they have been linked to systemic diseases. In addition, the American Academy of Pediatrics and National Academy of Medicine do not recommend that children consume these beverages.

Dental Sealant Prevalence Among Children with Special Health Care Needs: National Health and Nutrition Examination Survey (NHANES) 2013 to 2014.

Purpose: The purpose of this study was to evaluate dental care access and sealants prevalence among children with special health care needs. Methods: The authors utilized the publicly available National Health and Nutrition Examination Survey (NHANES) 2013 to 2014 datasets collected by trained dental examiners for the Centers for Disease Control and Prevention. This study included 2,651 six- to 19-year-olds who provided demographic, dental visit, disability, and sealants information. Weighted prevalence estimates and odds ratios (OR) were calculated for sealant use by disability, gender, age, race, and economic status. Results: Approximately 68 percent of participants had a dental visit in the past six months, with 84 percent of them being routine dental visits; each had approximately two sealed teeth (mean equals 2.37). Children with a physical disability have lower odds of having a sealant (OR equals 0.5; P=0.04) compared to nondisabled children. Six- to 11-year-olds have lower odds of having a sealant versus older age groups. Sealant use prevalence was lowest among African American children (39 percent) versus Hispanic (47 percent) and Caucasian (54 percent; P=0.01) children. Conclusions: The findings indicate disparities in dental sealants use among those with physical disabilities and younger age groups. Further studies and strategies are needed to intervene at an early age and increase utilization of sealants among children with special health care needs.

Dentists' perspective about dental amalgam: current use and future direction.

OBJECTIVES: In 2013, the United Nations Environment Programme (UNEP) reached a binding agreement - a.k.a. the Minamata treaty - to decrease dental amalgam use. This study aims to investigate US dentists' current practice and opinions about amalgam use, and to determine factors affecting their amalgam use and opinions. METHODS: A total of 45,557 general dentists and 5,101 pediatric dentists were invited to participate in a pre-tested electronic survey. The survey consisted of 12 close-ended questions using a 5-point Likert Scale. The Qualtrics™ software was used to distribute the survey, followed by three reminders. RESULTS: Response rate was 5.2 percent for general dentists, and 17.6 percent for pediatric dentists. Sixty-two percent of general dentists and 56 percent of pediatric dentists reported using amalgam. Most dentists disagreed with banning amalgam, while agreeing with installing amalgam separators. Environmentally conscious dentists were more likely to agree with banning amalgam and installing amalgam separators. CONCLUSION: Responding dentists favor the continued use of dental amalgam. Their perspectives vary by several factors including dentists' environmental consciousness. Policies toward minimizing amalgam's environmental impact need to be implemented.

Evaluating a Cultural Competency Curriculum: Changes in Dental Students' Perceived Awareness, Knowledge, and Skills.

In response to current and projected demographic changes in the United States, many dental schools have taken steps to increase the cultural competence of their students through various educational methods. The aim of this study was to evaluate the effectiveness of the cultural competency curriculum at Boston University Henry M. Goldman School of Dental Medicine (GSDM). The curriculum was evaluated using a pre and post design, utilizing an instrument developed for pharmacy students and modified for dental students. The questionnaire was comprised of 11 items designed to assess changes in students' awareness, knowledge, and skills in providing culturally competent care. Data were collected for two classes of second-year DMD students and first-year Advanced Standing students. The total number of returned surveys was 485, for a response rate of 79.5%. The students' post-curriculum mean scores were all higher than their pre-curriculum scores for overall cultural competence (pre 26.5±6.3 to post 29.8±7.2) and for individual subscores on awareness (pre 5.3±1.4 to post 5.5±1.5), knowledge (pre 7.2±1.9 to post 8.1±2.1), and skills (pre 14.1±4.4 to post 16.2±4.4). The improvements on all scores were statistically significant (p<0.0001), with the exception of the awareness component. This evaluation suggests that the cultural competency curriculum at GSDM has been effective in producing improvements in these students' cultural competence in the domains of knowledge and skills.

Dental professionals' knowledge and perceived need for education in bioterrorism preparedness.

Dental professionals should be well prepared to provide care during bioterrorist events. In this study, we assessed the knowledge, opinions about playing various roles during a bioterrorist event, and perceived need for education of dental professionals (dentists and dental hygienists) from one region (Oregon) that had been exposed to bioterrorism and from another region (New England) not exposed. This cross-sectional study used an eighteen-item pretested, self-administered questionnaire distributed at the 2005 Oregon Dental Conference (n=156) and 2005 Yankee Dental Conference (n=297). Dental professionals' knowledge and perceived need for education on bioterrorist preparedness were quantified by multivariate linear and logistic modeling. More than 90 percent of the dental professionals were willing to provide care during bioterrorist events. Perceived knowledge was high; however, actual knowledge was low. Dental professionals who wanted to attend a continuing education course and who thought dental professionals should play more roles during a bioterrorist attack had higher actual knowledge. Willingness to provide care was not supported by adequate knowledge. No significant differences between New England and Oregon dental professionals were observed in terms of actual knowledge or perceived need for bioterrorism education. Integrating training and education into the predoctoral dental and dental hygiene curricula and developing continuing education courses would improve knowledge and better prepare dental professionals to effectively perform American Dental Association-recommended roles during any future bioterrorism events.

Oral health status of refugee torture survivors seeking care in the United States.

We assessed the oral health status of 216 refugee torture survivors seeking care at an urban torture treatment center in the United States. Results showed that patients' dental health ranged from poor to fair; 76% had untreated cavities, and approximately 90% required immediate or near-immediate dental care. Torture treatment centers, in addition to offering safe environments for educating and examining patients, are ideal settings to provide basic oral health services without the risk of retraumatization.

Willingness of New England dental professionals to provide assistance during a bioterrorism event.

A bioterrorism attack could overwhelm medical personnel and facilities, suggesting a need for aid from nonmedical personnel. The American Dental Association suggests that dental professionals should assist in such cases, utilizing their strong scientific and technical skills. This study describes New England dental professionals' willingness, potential roles, motivators, and barriers to providing this aid. This cross-sectional study used a self-administered survey to collect data addressing the knowledge and opinions of dental professionals concerning acting as responders. The survey was distributed to 370 attendees of the 2005 Yankee Dental Conference, in Boston, Massachusetts. Most dental professionals expressed willingness to help during an attack (N = 340, 92%), reporting that dental professionals, in general, should perform a mean number of 6 roles. Three-quarters of dentists and dental students were personally willing, with proper training, to give immunizations, and 54% would perform triage. Knowledge was weak, but most dental professionals were interested in obtaining further education (83%). Since dental professionals are willing to assist during a bioterrorism attack and are motivated to obtain disaster response training, government officials and local directors and managers of disaster/emergency response agencies should consider incorporating dental professionals into their disaster management plans.

The association between cumulative periodontal disease and stroke history in older adults.

BACKGROUND: Since the late 1980s, several studies have been conducted to investigate the relationship between periodontal disease and ischemic stroke. The purpose of this study is to investigate the relationship of periodontal disease to the self-reported history of stroke in the elderly (60 years of age and older) by examining the data of the Third National Health and Nutrition Examination Survey (NHANES III). METHODS: Data from NHANES III, a large population-based cross-sectional survey of the United States, were used for this study. Because 1,563 of the 5,123 subjects in the study were edentulous, and periodontal disease is a major cause of tooth loss, it was necessary to account for edentulousness in the statistical analysis to avoid bias. Hence, a new index called the periodontal health status (PHS) index was developed to address this problem. Two measures of PHS were developed: PHS I, based on the median percentage of sites with >/=2 mm clinical attachment loss (CAL), and PHS II, based on the median percentage of sites with >/=3 mm CAL. Multiple logistic regression analysis was used to test for the association of PHS with stroke history. Two types of a multiple logistic regression model were fit: 1) logistic regression modeling with adjustment for age and tobacco use only; and 2) logistic regression modeling with adjustment of all statistically significant confounders. RESULTS: Based on multiple logistic regression analysis of PHS with adjustment for age and tobacco use only, completely edentulous elderly adults (PHS Class 5) and partially edentulous (teeth in one arch) elderly adults with appreciable clinical attachment loss (PHS Class 4) were significantly more likely to have a history of stroke compared to dentate adults (teeth in both arches) without appreciable clinical attachment loss (PHS Class 1). When multiple logistic regression models were fit with adjustment of all significant confounders, no statistically significant association was found between PHS and stroke. CONCLUSIONS: Based on the results of this study, there is evidence of an association between cumulative periodontal disease, based on PHS, and a history of stroke. However, it is unclear whether cumulative periodontal disease is an independent risk factor for stroke or a risk marker for the disease.

Are varicose veins a marker for susceptibility to coronary heart disease in men? Results from the Normative Aging Study.

Clinical observations suggest that varicose veins (VV) are less frequent in patients undergoing infrainguinal bypass surgery for femoral artery occlusive disease. While some previous studies support this relationship, others report that VV are more prevalent in coronary heart disease patients (CHD). This study used the Normative Aging Study (NAS) population to examine the association between VV and symptomatic CHD. The incidence of CHD over 35 years of follow-up was determined in the 2280 initially healthy male volunteers enrolled in the NAS. The incidence of CHD in the VV population and the subjects without VV were compared using Kaplan-Meier survival curves and the log-rank test. A time-dependent proportional hazards regression method was used to further explore the relationship between VV disease and subsequent development of CHD after adjusting for other cardiovascular risk factors. A total of 569 subjects (24.9%) were diagnosed with VV prior to the development of symptomatic CHD, and 1708 (75.1%) were not. Over 35 years of follow-up, 98 subjects with VV developed symptomatic CHD (17.2%), while 363 of those without VV subsequently developed symptomatic CHD (21.2%). Kaplan-Meier survival curves suggested a reduced risk of symptomatic CHD for subjects with VV (p = 0.0001). Further exploration of this relationship in a proportional hazards multivariate model showed VV to be associated with a 36% decreased risk of symptomatic CHD after adjusting for other recognized cardiovascular risk factors. In the NAS population, men with VV were less likely to develop symptomatic CHD over the 35+ years of follow-up than were subjects without VV.
