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

Chronic oral disease burden at the first 1000 days: Intergenerational risk factors, BRISA cohort

OBJECTIVE

To analyze multiple-causal models, including socioeconomic, obesity, sugar consumption, alcohol smoking, caries, and periodontitis variables in pregnant women with early sugar exposure, obesity, and the Chronic Oral Disease Burden in their offspring around the first 1000 days of life.

METHODS

The BRISA cohort study, Brazil, had two assessments: at the 22nd-25th gestational weeks and during the child's second year (n = 1141). We proposed a theoretical model exploring the association between socioeconomic and pregnancy factors (age, smoking, alcohol, sugars, obesity, periodontitis, and caries) and child's variables (sugars and overweight) with the outcome, Chronic Oral Disease Burden (latent variable deduced from visible plaque, gingivitis, and tooth decay), using structural equation modeling.

RESULTS

Caries and periodontitis were correlated in pregnant women. Addictive behaviors in the gestational period were correlated. Obesity (Standardized coefficient - SC = 0.081; p = 0.047) and added sugar consumption (SC = 0.142; p = 0.041) were observed intergenerationally in the pregnant woman-child dyads. Sugar consumption by the children (SC = 0.210; p = 0.041) increased the Chronic Oral Disease Burden.

CONCLUSIONS

Poor caries and periodontal indicators were correlated in pregnant women and their offspring. Obesity and sugar consumption act intergenerationally. Oral health in early life may change life trajectory since the worst oral conditions predict main NCDs.

Sugar-sweetened beverage consumption and periodontitis among adults: A population-based cross-sectional study

AIM

Investigating the association between sugar-sweetened beverages (SSBs) and periodontitis and whether the awareness of diabetes modifies this relationship.

MATERIALS AND METHODS

Cross-sectional analysis was conducted using the National Health and Nutrition Examination Survey (NHANES III) data involving US adults aged 30-50. Periodontitis was classified according to the Centers for Disease Control and Prevention and American Academy of Periodontology (CDC-AAP), and SSB consumption as dichotomous (<5 or ≥5, <7 or ≥7 and <14 or ≥14 times/week), ordinal and continuous variables. Confounders included family income poverty ratio, education, race/ethnicity, sex, age, food energy intake, smoking and alcohol. Odds ratios (ORs) were obtained by logistic regressions using inverse probability weighting. Effect modification analysis was performed considering self-reported diabetes.

RESULTS

Among 4473 cases analysed, 198 self-reported diabetes. SSBs were associated with periodontitis when individuals consumed ≥5 (OR 1.64; 95% confidence interval [CI] = 1.30-2.06), ≥7 (OR 1.92; 95% CI = 1.50-2.46) and ≥14 (OR 2.19; 95% CI = 1.50-3.18) times/week. The combined effect of consuming SSBs (≥5 and ≥14 times/week) and self-reported diabetes had less impact than the cumulative effect.

CONCLUSIONS

SSB consumption was associated with higher odds of periodontitis, and the estimates were reduced among those with awareness of diabetes.

Intake and serum levels of micronutrients and chronic oral diseases burden

OBJECTIVE

To investigate pathways from micronutrient intake and serum levels to Chronic Oral Diseases Burden.

METHODS

We analyzed cross-sectional data from NHANES III (n = 7936) and NHANES 2011-2014 (n = 4929). The exposure was the intake and serum levels of vitamin D, calcium, and phosphorus. Considering the high correlation of those micronutrients in the diet, they were analyzed as a latent variable dubbed Micronutrient intake. The outcome was the Chronic Oral Diseases Burden, a latent variable formed by probing pocket depth, clinical attachment loss, furcation involvement, caries, and missing teeth. Pathways triggered by gender, age, socioeconomic status, obesity, smoking, and alcohol were also estimated using structural equation modeling.

RESULTS

In both NHANES cycles, micronutrient intake (p-value < 0.05) and vitamin D serum (p-value < 0.05) were associated with a lower Chronic Oral Diseases Burden. Micronutrient intake reduced the Chronic Oral Diseases Burden via vitamin D serum (p-value < 0.05). Obesity increased the Chronic Oral Diseases Burden by reducing vitamin D serum (p-value < 0.05).

CONCLUSION

Higher micronutrient intake and higher vitamin D serum levels seem to reduce Chronic Oral Diseases Burden. Healthy diet policies may jointly tackle caries, periodontitis, obesity, and other non-communicable diseases.

Antineoplastic therapy is an independent risk factor for dental caries in childhood cancer patients: a retrospective cohort study

PURPOSE

To evaluate the antineoplastic therapy (AT) as a risk factor for dental caries lesions independent of other risk factors such as income, family education, stimulated salivary flow rate, hygiene habits, frequency of sugar intake, and microbiota in childhood cancer (CC) patients.

METHODS

72 individuals were divided into CC patients (n=36) and healthy individuals (control group - CT n=36). Demographic data, hygiene habits, frequency of sugar intake, CC type, and AT were collected. Stimulated salivary flow rate was measured and the presence and concentration of Streptococcus mutans were assessed using a real-time polymerase chain reaction (qPCR) technique. Clinical evaluations included plaque index (PI) and decayed-missing-filled-teeth index (dmft/DMFT). Descriptive statistics, T-test, Mann-Whitney test, chi-square test, Fisher's exact test, and two-way analysis of variance were used for data analysis (p<0.05).

RESULTS

At the time of oral evaluation, both groups exhibited similar ages with means of 12.0±3.9 years old for CC and 12.0±4.0 years old for CT patients. All CC patients underwent chemotherapy with nine also undergoing radiotherapy. Significant differences were observed between the groups in terms of color/race, income, family education, and hygiene habits. However, no statistically significant differences were found between groups regarding the frequency of sugar intake, stimulated salivary flow rate, or the concentration of Streptococcus mutans (qPCR technique). For clinical parameters, the DMF (CC:1.80, CT: 0.75), decayed (CC: 0.88, CT: 0.19), missing (CC: 0.25, CT:0), and PI (CC: 30.5%, CT: 22.6%) were higher in the CC group (p<0.05).

CONCLUSION

Childhood cancer (CC) patients undergoing antineoplastic therapy (AT) exhibit a higher prevalence of dental caries, regardless of income/education, frequency of sugar intake, stimulated salivary flow rate, and microbiota.

Ultra-processed food consumption and children and adolescents' health

OBJECTIVES

To present observational studies investigating associations between the consumption of ultra-processed foods and health outcomes in childhood and adolescence.

DATA SOURCE

Observational, cross-sectional, or longitudinal studies were considered, and identified in the Scopus, Web of Science, Pubmed and Scielo databases, without date restrictions.

DATA SYNTHESIS

The most frequent combinations of risk factors in children and adolescents involved an unhealthy diet, with regular consumption of ultra-processed foods to the detriment of a diet based on fresh or minimally-processed foods and insufficient levels of physical activity; records on alcohol and tobacco use were identified. Combined, these practices contribute to the findings that indicate an increase in the prevalence of obesity in children and adolescents and a sedentary lifestyle, with a decrease in physical activity, in addition to representing a risk for the development of chronic non-communicable diseases, such as cardiovascular diseases and periodontal disease in childhood and adolescence.

CONCLUSIONS

The present study maps the current literature on the topic and indicates the direction of the approach for health promotion and prevention of NCDs in children and adolescents. Among the different risk factors that negatively affect the full development of this population, frequently eating breakfast and practicing physical activity is most strongly associated with a lower consumption of ultra-processed foods and should be part of an integrated approach to promoting eating practices that favor the reduction of diseases also in adult life.

Sugar intake above international recommendations and oral disease burden: A population-based study

OBJECTIVE

To evaluate the association between added sugar intake above the daily limit for the risk of noncommunicable diseases (NCDs) and the Chronic Oral Disease Burden in adolescents.

METHODS

This was a population-based study using cross-sectional data nested to RPS Cohorts Consortium, São Luís, Brazil, from the 18-19-year-old follow-up (n = 2515). High consumption of added sugars was estimated according to the limits of the World Health Organization guidelines (WHO) (≥5% of total energy/day) and the American Heart Association statement (AHA) (≥25 g/day). The Chronic Oral Disease Burden was a latent variable (number of decayed teeth, periodontal probing depth ≥4 mm, clinical attachment level ≥3 mm, and bleeding on probing). Models were adjusted for Socioeconomic Status, sex, obesity, and plaque index and analyzed through structural equation modeling.

RESULTS

Adolescents had high sugar consumption according to the WHO (78.6%) and AHA (81.4%) recommendations. High sugar intake, according to WHO (SC = 0.096; p = 0.007) and AHA (SC = 0.056; p = 0.027), was associated with a heavier Chronic Oral Disease Burden. Even half of the recommended dose was sufficient to affect some oral disease indicators.

CONCLUSION

Sugar intake over international statements to prevent NCDs is associated with higher Chronic Oral Disease Burden among adolescents.

Systems mapping of multilevel factors contributing to dental caries in adolescents

Dental caries is a prevalent chronic disease among adolescents. Caries activity increases significantly during adolescence due to an increase in susceptible tooth surfaces, immature permanent tooth enamel, independence in pursuing self-care, and a tendency toward poor diet and oral hygiene. Dental caries in permanent teeth is more prevalent among adolescents in low-income families and racial/ethnic minority groups, and these disparities in adolescent dental caries experience have persisted for decades. Several conceptual and data-driven models have proposed unidirectional mechanisms that contribute to the extant disparities in adolescent dental caries experience. Our objective, using a literature review, is to provide an overview of risk factors contributing to adolescent dental caries. Specifically, we map the interactive relationships of multilevel factors that influence dental caries among adolescents. Such interactive multilevel relationships more closely reflect the complex nature of dental caries experience among the adolescent population. The methods that we use are two-fold: (1) a literature review using PubMed and Cochrane databases to find contributing factors; and (2) the system dynamics approach for mapping feedback mechanisms underlying adolescent dental caries through causal loop diagramming. The results of this study, based on the review of 138 articles, identified individual, family and community-level factors and their interactions contributing to dental caries experience in adolescents. Our results also provide hypotheses about the mechanisms underlying persistence of dental caries among adolescents.

Conclusions

Our findings may contribute to a deeper understanding of the multilevel and interconnected factors that shape the persistence of dental caries experience among adolescents.

The co-occurrence of the two main oral diseases: periodontitis and dental caries

OBJECTIVES

Limited studies are available testing through multiple regression models the association between the two main oral diseases: dental caries and periodontitis. The aim of this cross-sectional population-based study was to verify whether dental caries and periodontitis co-occur in a representative sample of the South Korea population.

MATERIALS AND METHODS

A total of 23,405 subjects representative of 36.2 million of adults (KNHANES) were examined. Univariate and multiple regression analyses using 7 different models were applied, controlling for age, gender, smoking status, frequency of toothbrushing, use of interproximal toothbrushes and flossing, educational level, income, gum diseases treatment and tooth filling in the previous year, BMI, Vitamin D serum levels, alcoholism, diabetes status, stress and carbohydrates dietary intake.

RESULTS

In the fully adjusted model, participants with periodontitis had, respectively, a mean of 0.82 (95% CI: 0.41-1.23) and of 0.36 (95% CI: 0.22-0.50) more untreated decayed surfaces and teeth than participants without periodontitis, with an OR to have at least one untreated decayed surface of 1.96 (95% CI: 1.66-2.32). However, cumulative caries experience (DF scores) and periodontitis were not associated.

CONCLUSIONS

In this large nationally representative population, periodontitis and untreated dental caries co-occur. However, when considering cumulative caries experience (DF scores), the two diseases do not appear related.

CLINICAL RELEVANCE

In light of their possible co-occurrence, clinicians should implement integrative diagnostic, preventive and treatment strategies for both diseases.

Sugar-sweetened beverages and periodontal disease: A systematic review

This systematic review aims to determine the association between the consumption of sugar-sweetened beverages (SSBs) and periodontal disease. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to conduct a literature search on five electronic databases till January 2022. Systemically healthy individuals consuming SSBs and presenting periodontal disease (gingivitis/periodontitis) were included. The modified Newcastle-Ottawa Scale and the Grading of Recommendation Assessment Development and Evaluation criteria were respectively used to assess the risk of bias and the evidence's quality. Of the 1303 eligible records identified in the initial search, ten studies (nine cross-sectional and one case-control) were selected for the final review. Among the included articles, five reported SSBs intake in the form of carbonated soft drinks, two as sugary drinks, two as soft drinks, and one as coffee with added sugar. Four studies reported gingivitis as an outcome, while the remaining six studies reported periodontitis using validated indices. The included studies were of medium to high quality. Consumption of SSBs may increase gingival bleeding, thereby gingivitis and the risk of periodontitis. Intake of added sugars like SSBs should be considered as a potential factor during gingival/periodontal risk assessment. Further studies are warranted to establish additional evidence of association.

Antineoplastic therapy in childhood cancer patients presents a negative impact in the periodontal tissues: a cohort study

OBJECTIVES

To investigate the effect of antineoplastic therapy (AT) in the periodontal tissues of childhood cancer (CC) patients.

MATERIALS AND METHODS

Seventy-two individuals were divided into CC (n=36) and healthy individuals (control group-CG, n=36). Demographics, hygiene habits, CC type, and AT were collected. Salivary flow and the presence and concentration of Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Tannerella forsythia, and Fusobacterium nucleatum were analyzed. Clinical evaluation included plaque (PI) and gingival indexes (GI), periodontal probing depth (PPD), and clinical attachment level (CAL). Patients were classified into periodontal health, gingivitis, or periodontitis. Descriptive statistics, T test, Mann-Whitney test, chi-square, Fisher's exact test, and two-way analysis of variance were used (p<0.05).

RESULTS

The mean age of the patients was similar (CC 12.0±3.9 years and CG 12.0±4.0 years). In the CC group, all patients underwent chemotherapy and nine radiotherapy. Color/race, income, and family education showed significant differences between groups. There was no difference between groups in salivary flow. Higher levels of Fusobacterium nucleatum were seen in CC (p=0.02). Significant difference between groups was found for PI (CC: 30.5%, CG: 22.6%), GI (CC: 28.8%, CG: 17.3%), PPD (CC: 1.77 mm, CG: 1.61 mm), and CAL (CC: 1.77 mm, CG: 1.57 mm), periodontal health (CC: 3, CG: 7), gingivitis (CC: 16, CG: 24), or periodontitis (CC: 17, CG: 5).

CONCLUSION

AT in CC patients presents a negative impact in the periodontal and microbiological parameters.

CLINICAL RELEVANCE

Childhood cancer individuals showed worse periodontal parameters and higher levels of Fusobacterium nucleatum in the saliva when compared to healthy individuals.

Precursors of insulin resistance underlying periodontitis in adolescents aged 17-18 years

OBJECTIVE

To investigate the association between insulin resistance markers and periodontitis in adolescents, analyzing confounder variables and the adiposity as a mediator.

METHODS

This is population-based study is representative of adolescents aged 17-18 years from public schools in São Luís, Brazil (n = 405). Insulin resistance was assessed using the Model of Assessment of the Homeostasis of the Insulin Resistance Index (HOMA-IR) and its percussor triglycerides/HDL-cholesterol ratio (TG/HDL-c). The outcome was Initial Periodontitis, a latent variable estimated by the common variance shared among bleeding on probing, probing depth ≥ 4 mm, and clinical attachment loss ≥ 4 mm. The association between insulin resistance and Initial Periodontitis was modeled via pathways triggered by socioeconomic status, smoking, alcohol, and Adiposity, using structural equation modeling.

RESULTS

Higher TG/HDL-c was directly associated with higher Initial Periodontitis (standardized coefficient [SC] = 0.130, p < 0.001). HOMA-IR was not associated with periodontal outcome (SC = 0.023, p = 0.075), but it was with Adiposity (SC = 0.495, p < 0.001). Higher TG/HDL-c was associated with Adiposity (SC = 0.202, p < 0.001).

CONCLUSION

The insulin resistance markers were associated with early signs of periodontal breakdown among adolescents, suggesting a possible relationship between diabetes and periodontitis commences early in life.

Obesity, Insulin Resistance, Caries, and Periodontitis: Syndemic Framework

(1) Background: To investigate the grouping of obesity and insulin resistance with caries and periodontitis from a syndemic perspective through pathways of socioeconomic inequalities, smoking, alcohol, and high sugar consumption in adolescence. (2) Methods: The population-based RPS Cohort study, São Luís, Brazil, in ages 18-19 years (n = 2515) was used. The outcomes were the grouping of pbesity and Insulin Resistance Phenotype (latent variable formed by Triglycerides/HDL ratio, TyG index, and VLDL) and the Chronic Oral Disease Burden (latent variable comprising caries, bleeding on probing, probing depth ≥ 4 mm, clinical attachment level ≥ 3 mm, and visible plaque index ≥ 15%). Socioeconomic Inequalities influencing the Behavioral Risk Factors (latent variable formed by added sugar, smoking, and alcohol) were analyzed using structural equation modeling. (3) Results: Socioeconomic Inequalities were associated with the Chronic Oral Disease Burden [Standardized Coefficient (SC) = 0.222, p < 0.001]. Behavioral Risk Factors were associated with increased Chronic Oral Disease Burden (SC = 0.103; p = 0.013). Obesity was associated with the Insulin Resistance Phenotype (SC = 0.072; p < 0.001) and the Chronic Oral Disease Burden (SC = 0.066; p = 0.005). The Insulin Resistance Phenotype and the Chronic Oral Disease Burden were associated (SC = 0.053; p = 0.032). (4) Conclusion: The grouping of obesity and early events of diabetes with caries and periodontitis call for a syndemic approach in adolescence.

The pathways from disadvantaged socioeconomic status in childhood to edentulism in mid-to-late adulthood over the life-course

BACKGROUND

This study aimed to examine the direct and indirect pathways from childhood socioeconomic status (SES) to the prevalence of edentulism in mid-to-late age Chinese individuals using structural equation modeling (SEM).

METHODS

This study analyzed data from 17,032 mid- to-late age Chinese individuals in the 2014 and 2015 China Health and Retirement Longitudinal Study (CHARLS). Childhood SES was determined based on the parents' education and occupation, financial situation of the family, primary residence, food availability, and medical convenience. Adulthood SES was established according to educational achievements of the individuals. Edentulism is defined as the loss of all natural teeth. SEM was used to examine the statistical significance of the association between childhood SES and edentulism, mediated by childhood health, adulthood SES, and adult health.

RESULTS

Childhood SES had significant indirect (β = -0.026, p < 0.01), and total (β = -0.040, p < 0.01) effects on edentulism. It was determined that 65% of the total effect of childhood SES on edentulism was indirect, and mainly mediated by adult SES. Also, the goodness-of-fit indices of the best-fitting model were acceptable.

CONCLUSION

This study revealed that childhood health, adult health and adult SES are mediators that explain the relationship between childhood SES and edentulism. The global attention to alleviate the inequality in edentulism should focus on exploring recommendations and intervention strategies from childhood to adulthood, by considering adult SES, childhood and adult health.

Chronic oral diseases burden: The confluence of caries and periodontitis throughout life

AIM

To investigate the confluence of caries and periodontitis indicators from adolescence to elderhood among Americans.

MATERIALS AND METHODS

This cross-sectional study explored the grouping among a set of caries and periodontitis indicators (the proportion of sites with bleeding on probing, moderate probing pocket depth [PPD, 4-5 mm], severe PPD [≥6 mm], moderate clinical attachment level [CAL, 3-4 mm], severe CAL [≥5 mm], number of teeth with furcation involvement, number of decayed teeth, number of teeth with pulp involvement, and the number of missing teeth) in 14,421 Americans from the NHANES III study. Exploratory factorial analysis was used to determine the constructs between those indicators (factorial loading ≥0.3). These analyses were stratified by age and confirmed with a confirmatory factorial analysis. We also performed a sensitivity analysis using the NHANES 2011-2014.

RESULTS

Two constructs were extracted. The first, Chronic Oral Diseases Burden, grouped caries indicators with moderate PPD and moderate CAL for the youngest subjects (13-39 years old), while for the subjects over 50 years, the Chronic Oral Disease Burden grouped caries indicators with severe CAL and PPD and furcation involvement. The second construct, Periodontal Destruction, grouped only periodontitis indicators.

CONCLUSIONS

Caries and periodontitis indicators grouped consistently across the different age ranges in lapse times of 25 years.

Association between Four Dietary Patterns and the Risk of Periodontal Diseases: A Systematic Review and Meta-Analysis

Background: Several dietary patterns are reported as risk factors for several chronic diseases including oral diseases. However, thus far, there has been no comprehensive quantitative analysis of nutrition and periodontal diseases. Methods: This systematic review was conducted according to the PRISMA guidelines. Cohort, case–control, and cross-sectional studies were eligible for inclusion in this study. The Newcastle–Ottawa scale was used to qualitatively assess the risk of bias in the included studies. The number of samples was used for odds ratio calculation, followed by the unadjusted value and 95% confidence interval. Results: Nine papers were included for the systematic review and meta-analysis. The results of screening for database search records showed that four diet patterns (western diet, dairy product intake, sugar intake, and vitamin C intake) have enough data for meta-analysis. The risk of periodontal disease in the western-diet group and the lowest dairy product intake group was 1.05 (0.51–2.13) and 1.28 (0.89–1.84), respectively. The risk of periodontal disease in the highest sugar intake group and the lowest vitamin C intake group was 1.52 (0.79–2.91) and 1.15 (1.08–1.23), respectively. Conclusions: With aging of the population globally, the prevalence of periodontal disease increases, and the associated cost also increases. Though this study, we found foods related to the risk of periodontal disease, and we are confident that it will contribute to lowering the incidence of the disease.

Influence of digital media in the oral health education of mother-child pairs: study protocol of a parallel double-blind randomized clinical trial

Background

Dental caries is the most common non transmissible chronic disease in childhood and the control of dental biofilm in children is one of the greatest challenges in oral disease prevention. Digital media applications can help patients in improving their oral hygiene performance and reducing the number of appointments due to pain and discomfort reasons. This study aims to investigate the use of an smartphone application (WhatsApp) to deliver oral health education to mother-child pairs, with the ultimate goal of controlling dental biofilm and caries through digital activities focused on oral hygiene.

Methods

This study was designed as a randomized, double-blind, parallel clinical trial involving 100 pairs of mothers and children (6–12 years old). The mothers and children will be randomly allocated to the control group (n = 50 pairs), who will receive a single visit conventional oral health education, or to the experimental group (n = 50 pairs), who will receive both a single visit conventional oral health education and educational videos through WhatsApp Messenger, twice a week. Before randomization of the groups and after the intervention, pairs will be evaluated regarding to plaque index (VPI), gingival bleeding index (GBI), and number of decayed, missing and filled permanent or primary teeth (DMF-T) modified by the inclusion of active non-cavitated carious lesions (Nyvad criteria). Socioeconomic data, dental history, and oral health literacy will obtained using questionnaires (Oral Health Literacy Assessment Task for Paediatric Dentistry; BOHLAT-P). Chi-square, Student’s t-test, paired Student’s t-test, Mann-Whitney, and Friedman tests will be used with a 5% significance level.

Discussion

This intervention proposal is designed to motivate behavioral change in mother-child pairs. We hypothesize that adding digital media to traditional oral health programs will provoke improvements in oral hygiene behavior and health outcomes. To our knowledge, this is the first study evaluating the effect of educational videos communicated by digital media (WhatsApp) on the oral health of mother-child pairs evaluated by long-term dental examinations. In addition, we will assess the maternal level of comprehension of the provided information via a literacy assessment tool. The clinical trial is registered at the Brazilian Registry of Clinical Trials (No. RBR-7s8bw6m).

Correlation between the beverage serving activities and the dental use of health care resources of National Health Insurance for common oral diseases

Background/purpose

: Taiwanese get use to drinking hand-shaken beverages. However, excessive sugar intake is strongly associated with the occurrence of dental caries. This study evaluated the correlation between the beverage serving activities and the dental use of National Health Insurance (NHI) for common oral diseases in 2016.

Materials and methods

Data on the population, the beverage serving activities, and the dental records of NHI were obtained from the related websites of government. These data were divided by cities and counties to investigate the beverage serving activities and the dental use of NHI for common oral diseases in 2016.

Results

In Taiwan, the value of beverage consumption per person had a moderate to high positive correlation with the dental use rate, the number of out-patient visits per 1,000 people, and the medical expenses per person for common oral diseases. For dental caries, diseases of pulp & periapical tissues, and gingivitis & periodontal diseases, their Pearson’s r values were 0.52–0.61, 0.18–0.40, and 0.58–0.65, respectively. These results indicate that the higher the beverage consumption per capita, the higher the dental use per capita.

Conclusion

There is a long-term benefit for oral health and systemic health through reducing or avoiding unnecessary excessive sugar intake. Therefore, from a cost-effectiveness viewpoint, Taiwan government should develop a better oral health care policy including a health education strategy of appropriate sugar intake to prevent dental caries and other non-communicable diseases in Taiwanese people.

Pathways in the association between added sugar consumption, obesity in mother-child dyads, and chronic oral disease burden in early childhood

In this study, we modeled the pathways in the association of socioeconomic status, frequency of added sugar consumption, and obesity in mother-child dyads with chronic oral disease burden in early childhood using structural equation modeling. A population-based study was conducted on preschoolers from public daycare centers in São Luís, Brazil (n = 674) and their mothers. Chronic oral disease burden in early childhood was a latent variable, representing the shared variance of the following indicators: visible plaque index, gingivitis, and dental caries. A higher consumption frequency of added sugars by children [standardized regression coefficient (SC) = 0.219] explained the chronic oral disease burden. A higher consumption frequency of added sugars by mothers was associated with greater consumption of sugar by children (SC = 0.236), and indirectly with a greater chronic oral disease burden (SC = 0.052). Maternal obesity was associated with obesity in the offspring (SC = 0.130). The chronic oral disease burden is already present in early childhood and can be explained by the higher consumption of added sugars by the mother-child dyad. Approaches to preventing chronic oral diseases should focus on common risk factors, start early in life, and promote family involvement in this process.

Socio-demographic factors, dental status, oral health knowledge and attitude, and health-related behaviors in dental visits among 12-year-old Shenzhen adolescents: a multilevel analysis

Background

Dental visits can provide education, prevention and treatment measures for teenagers, and help to form correct oral health knowledge and attitude. The purpose of this study was to evaluate the effects of socio-demographic factors, dental status, oral health literacy, and health-related behaviors on dental visits in early 12-year-old adolescents.

Methods

953 subjects aged 12 in Longhua district of Shenzhen were investigated. The questionnaire and clinical examination were applied in schools, and two-level logistic regression models were constructed to interpret the effect of individual and contextual factors on Shenzhen adolescents' dental visits.

Results

A total of 27.6% of the participants had not been to a dentist. After the multiple factors binary logistic regression analysis, it confirmed that the following variables: Shenzhen Hukou (OR 2.133, 95% CI 1.429–3.185), moderate caries (OR 1.404, 95% CI 1.022–1.928) and severe caries (OR 2.546, 95% CI 1.461–4.437), Angle Class II malocclusion (OR 1.703, 95% CI 1.134–2.556), sometimes or never toothbrushing (OR 2.985, 95% CI 1.491–5.975), dental floss usage (OR 1.829, 95% CI 1.250–2.677), having had a toothache within the last 12 months (OR 1.469, 95% CI 1.086–1.986), high knowledge attitude level (OR 1.570, 95% CI 1.106–2.229), moderate knowledge attitude level (OR 1.534, 95% CI 1.073–2.193), were associated factors for dental visit experience.

Conclusions

The dental visits of 12-year-old children in Longhua district of Shenzhen is affected by multi-dimensional factors. It is suggested that oral health education should be strengthened, good oral hygiene habits should be cultivated, and the needs and utilization of oral health services for non-Shenzhen Hukou adolescents should be paid attention to, so as to effectively improve the overall oral health level of adolescents.

Association of Oral Health Conditions in Adolescents with Social Factors and Obesity

This study aimed to investigate associations between psychosocial factors, obesity, and oral health in a study population of 10- to 18-year-old adolescents who participated in the LIFE Child study. Psychosocial information (socioeconomic status (SES) based on parents’ education, occupation and household income, Strengths and Difficulties Questionnaire (SDQ), health-related quality of life) and physical activity behavior were obtained. Nutritional status was classified based on age- and sex-adjusted body mass index into underweight, overweight, normal weight and obese. Clinical dental examinations were performed and scored with respect to caries experience (CE), oral hygiene (OH), and periodontal status (periodontal health score: PERIO-S). Age-adjusted regression analysis under the assumption of a double Poisson distribution was performed with and without adjusting for SES (α = 5%). A total of 1158 study participants (590 girls, 568 boys; mean age 13.2 ± 2.3 years) were included (17.2% were classified as obese). CE was 20% higher for moderate and 60% higher for low SES compared to high SES (p < 0.05). PERIO-S was 10% higher for moderate and 30% higher for low compared to high SES (p < 0.05). Poor OH was associated with higher CE (Ratio R = 2.3, p < 0.0001) and PERIO-S (R = 3.1, p < 0.0001). Physical activity in a sports club was associated with lower CE-S and PERIO-S (R = 0.85, p < 0.001). Obesity was associated with increased CE (R = 1.3, p < 0.001) compared to normal weight. For low but not high SES, more reported difficulties were associated with higher CE. In conclusion, low SES, poor OH, and obesity are associated with unfavorable oral health conditions, whereas physical activity and high SES are potentially protective.

Resumo Introdução A inatividade física está associada à obesidade, inflamação crônica e ocorrência de doenças crônicas não transmissíveis. Objetivo Investigar a associação do comportamento ativo, índice de massa corporal (IMC) e pressão arterial diastólica (PAD) com os níveis séricos de interleucinas inflamatórias em adolescentes. Métodos Estudo transversal de base populacional de adolescentes da rede pública de São Luís, Maranhão. Construiu-se um modelo teórico, baseado na Modelagem com Equações Estruturais, para explorar os efeitos da variável latente “comportamento ativo” ajustada para a situação socioeconômica e sexo com efeitos no IMC, PAD e carga inflamatória. Resultados O comportamento ativo foi associado aos menores valores de PAD (coeficiente padronizado (CP) = -0,146; p = 0,029), enquanto o maior IMC foi associado a maiores valores de PAD (CP = 0,177; p < 0,001). Para os maiores valores do comportamento ativo houve maior carga inflamatória (CP = 0,442; p < 0,001) e o maior IMC foi associado à maior carga inflamatória (CP = 0,145;p = 0,025). Sexo feminino teve maior carga inflamatória (CP = 0,282; p < 0,001). Houve um efeito indireto para o sexo feminino nos menores valores de carga inflamatória via redução do comportamento ativo (CP = -0,155; p < 0,001). Conclusão O comportamento ativo reduz os níveis pressóricos em adolescentes, enquanto o aumento das citocinas inflamatórias induzidas pelo comportamento ativo pode estar envolvido na sua resposta anti-inflamatória para a prevenção de doenças.

Association of active behavior, body mass index, blood pressure and inflammatory cytokine in adolescents

Abstract Introduction Physical inactivity is associated with obesity, chronic inflammation and the occurrence of chronic non-communicable diseases. Objective: To investigate the association of active behavior, body mass index (BMI), diastolic blood pressure (DBP) with serum levels of inflammatory interleukins in adolescents. Methods Cross-sectional population-based study of adolescents from public schools in São Luís, Maranhão. A theoretical model was built, based on Structural Equation Modeling, to explore the effects of the latent variable “active behavior” adjusted for socioeconomic status and gender, with effects on BMI, DBP and inflammatory load. Results Active behavior was associated with lower DBP values (standardized coefficient (SC) = -0.146; p = 0.029), while higher BMI was associated with higher DBP values (SC = 0.177; p < 0.001). For the highest values of active behavior there was a higher inflammatory load (SC = 0.442; p < 0.001); and a higher BMI was associated with a higher inflammatory burden (SC = 0.145; p = 0.025). Female gender had a higher inflammatory burden (SC = 0.282; p < 0.001). There was an indirect effect for females on lower inflammatory load values via reduction in active behavior (SC = -0.155; p < 0.001). Conclusion Active behavior reduces blood pressure levels in adolescents; while the increase in inflammatory cytokines induced by active behavior may be involved in their anti-inflammatory response for disease prevention.

A Cross-Sectional Study of the Association Between Chronic Oral Disease Burden and Serum Biomarkers in Kidney Transplant Recipients

INTRODUCTION

Poor oral health can negatively affect general health and quality of life of kidney transplant recipients. The study aimed to investigate the association between chronic oral disease burden, serum biomarkers, and comorbidities in kidney transplant recipients.

DESIGN

A cross-sectional comparative study was conducted with 44 patients after kidney transplant. The burden of chronic oral disease was composed of the following observable variables: moderate periodontitis and presence of dental caries. Serum biomarkers and comorbidities data were collected. The chi-square or Fisher's exact tests for categorical variables and Student's t-test or Mann-Whitney test for continuous variables were used. Robust Poisson regression was used to model the association.

RESULTS

Higher levels of mean uric acid (P = .01) and creatinine (P = .03) were observed in the group of patients with oral disease burden, while the highest level of high-density lipoprotein was observed in the group without oral disease. Higher values of uric acid were associated with the occurrence of chronic oral disease burden (Adjusted PR = 1.24, 95% CI: 1.03-1.48, P = .019). There was no statistical difference between the groups with and without oral disease burden in comorbidities present.

CONCLUSION

The findings suggest that chronic oral diseases burden can be associated with uric acid and creatinine levels in kidney transplant recipients.

Prevalence of overweight and obesity among Brazilian adolescents over time: a systematic review and meta-analysis

OBJECTIVE

To estimate the burden of excess weight in Brazilian adolescents.

DESIGN

Systematic review with meta-analysis.

SETTING

We searched the literature in four databases (MEDLINE/PubMed, EMBASE, SciELO and LILACS). Studies were included if they had cross-sectional or cohort design and enrolled Brazilian adolescents. Studies based on self-reported measures were excluded. Random effect models were used to calculate prevalence estimates and their 95 % CI.

PARTICIPANTS

Brazilian adolescents (10 to 19 years old).

RESULTS

One hundred and fifty-one studies were included. Trend analyses showed a significant increase in the prevalence of excess weight in the last decades: 8·2 % (95 % CI 7·7, 8·7) until year 2000, 18·9 (95 % CI 14·7, 23·2) from 2000 to 2009, and 25·1 % (95 % CI 23·4, 26·8) in 2010 and after. A similar temporal pattern was observed in the prevalence of overweight and obesity separately. In sensitivity analyses, lower prevalence of excess weight was found in older adolescents and those defined using International Obesity Task Force cut-off points. The Southeast and South regions had the highest prevalence of excess weight, overweight and obesity. No significant difference in prevalence by sex was found, except for studies before the year 2000.

CONCLUSIONS

The prevalence of overweight and obesity in Brazilian adolescents is high and continues to rise. Public policies on an individual level and targeting modifications in the obesogenic environment are necessary.

Risk factors for dental caries in Latin American and Caribbean countries

Identifying the risk factors for dental caries is vital in epidemiology and clinical practices for developing effective preventive strategies, both, at the individual and collective levels. Different causality/determination models have been proposed to understand the development process of dental caries. In the present review, we designed a model inspired by the world-known social determinants models proposed in the 90s and more recently in the 10s, wherein the contextual factors are placed more externally and encompass the individual factors. The contextual factors included those related to the cultural and societal values, as well as the social and health government policies. The individual factors were classified into the following categories: socioeconomic (social class, occupation, income, and education level), demographic characteristics (age, sex, and ethnicity), behavioral factors (non-use of fluoride dentifrice, sugar consumption, poor oral hygiene, and lack of preventive dental care), and biological factors (recent caries experience/active caries lesions, biofilm retentive factors, developmental defects of the enamel, disabilities, saliva amount and quality, cariogenic biofilm). Each of these variables was addressed, while focusing on the current evidence from studies conducted in Latin American and Caribbean countries (LACC). Based on the proposed model, educational aspects were addressed, and individual caries risk assessment and management decisions were proposed; further, implications for public health policies and clinical practice were described. The identification of modifiable risk factors for dental caries should be the basis for multi-strategy actions that consider the diversity of Latin American communities.

Systemic circulating inflammatory burden and periodontitis in adolescents

OBJECTIVES

To analyze the association between systemic inflammatory burden of cardiovascular disease (CVD) risk and periodontitis in adolescents, including mediating pathways triggered by their common risk factors.

MATERIALS AND METHODS

Using a population-based sample study (n = 405) of Brazilian adolescents (17-18 years old), direct and mediation pathways triggered by "Socioeconomic Status," "Adiposity," Smoking, and "Blood Pressure" were modelled for the association between the "Systemic Circulating Inflammatory Burden of CVD Risk" (IL-1β, IL-6, IL-8, TNF-α) and the "Initial Periodontitis" (bleeding on probing (BoP), probing depth (PD) ≥ 4 mm, clinical attachment loss (CAL) ≥ 4 mm), both as continuous latent variables, using structural equation modeling. Sensitivity analysis was performed for the outcomes "Gingivitis" (visible plaque; BoP); "Moderate Periodontitis" (PD ≥ 5 mm and CAL ≥ 5 mm) and periodontitis (CDC-AAP case definition).

RESULTS

Higher "Systemic Circulating Inflammatory Burden of CVD Risk" was directly associated with higher "Initial Periodontitis" (standardized coefficient [SC] = 0.178, P value < 0.001). Lower "Socioeconomic Status" (SC = - 0.022, P value = 0.015) and Smoking (SC = 0.030, P value = 0.021) triggered the "Initial Periodontitis", mediated by "Systemic Circulating Inflammatory Burden of CVD Risk". Sensitivity analysis showed a dose-response relationship between "Systemic Circulating Inflammatory Burden of CVD Risk" and "Moderate Periodontitis" (SC = 0.323, P value = 0.021).

CONCLUSIONS

"Systemic Circulating Inflammatory Burden of CVD Risk" appeared as an underlying mechanism of early periodontal breakdown in adolescents, also triggered by social vulnerability and smoking.

CLINICAL RELEVANCE

The association between periodontitis and CVD in adulthood seems to establish much earlier in life than had been previously studied, giving impetus to preventive approaches focused on their common risk factors.

The correlation of altitude with gingival status among adolescents in western China: a cross-sectional study

Periodontal disease is common in Chinese adolescents. There is little information about the effect of different altitudes on gingival health. This study aimed to investigate the gingival status at different altitudes and to identify relative factors that affect adolescents' gingival status. A total of 1033 adolescents aged 12-14 years were included in this cross-sectional study in Ganzi (plateau, 1400 m, 2560 m, 3300 m) and Suining (plain, 300 m). Gingival status was assessed by the presence of gingival bleeding on probing (BOP) and dental calculus (DC). Demographic variables, socioeconomic status, dairy habits and oral health-related knowledge, attitudes and behaviors were obtained via questionnaire. Univariate and multivariate binary logistic regression analyses were performed to identify potential relative factors. A total of 64.09% and 77.15% of adolescents had BOP and DC, respectively. The prevalence rates of BOP and DC were higher in the plateau than the plain (P < 0.05). After adjusting for all other factors and interaction terms, residence altitudes of 2560 m [300 m as reference: P < 0.001, odds ratio (OR) = 4.072] and 3300 m (300 m as reference: P = 0.002, OR = 4.053) were significant relative factors of BOP, and an altitude of 2560 m (300 m as reference: P = 0.001, OR = 3.866, 1400 m as reference: P = 0.001, OR = 3.944) was an important relative factor of DC. Gingival bleeding and calculus deposits were common at different altitudes. High altitude was a significant relative factor of gingival bleeding and calculus deposits.

Peculiarities of Dental Treatment among Paediatric Oncological Patients: a Case Report

Objectives

According to the National Cancer Institute of Lithuania, cancer is diagnosed for almost 100 children each year. Oncological patients suffer from complications during and after treatment. Radiation therapy also affects dental hard tissues. Many oncological patients lose motivation to take care of their oral hygiene because they are focused on cancer diagnosis. This case report discusses prevention and dental treatment severity after radiation therapy treatment.

Material and Methods

A 9-year-old boy with cancer diagnosis visited a dentist in 2017. The patient was complaining about poor aesthetic quality of the teeth, but there were no complaints about teeth sensitivity or pain. Different stages of active caries, poor oral hygiene, visible abundant plaque, swollen, red and bleeding gums were observed during appointment. A motivational interview explaining the importance of oral hygiene was conducted. Non-surgical caries treatment was prescribed during the first visit. Restorative treatment was performed after 1 month.

Results

The motivational interview explaining the importance of oral hygiene was conducted during every appointment per 3-year period. Unfortunately, oral hygiene is still poor due to the lack of motivation. Active-cavitated caries lesions were restored with glass ionomer cement and composite resin. The aesthetics of teeth was improved.

Conclusions

Oncological and recovered patients after radiation therapy should be assigned to a high risk of caries. These patients should be treated individually by the algorithm. Psychological or psychotherapeutic assistance is necessary for patients due to motivation for treatment and oral care.

Higher sugar intake is associated with periodontal disease in adolescents

OBJECTIVES

Analyze the association between higher added sugar exposure and periodontal disease in adolescents (18-19 years old).

MATERIALS AND METHODS

This was a cross-sectional study nested to RPS Cohorts Consortium, São Luís, Brazil (n = 2515). The exposure was percentage of daily calories from added sugar (≥ 10%), estimated from a quantitative food frequency. The outcome was periodontal disease estimated by the number of teeth affected by bleeding on probing, periodontal probing depth ≥ 4 mm, and clinical attachment level ≥ 4 mm at the same site. A theoretical model was depicted in a directed acyclic graph to identify the minimal sufficient adjustment set: household income, adolescent's educational level, sex, alcohol use, and smoking. Periodontal disease was categorized into < 2 teeth affected, 2 to 3 teeth affected, and ≥ 4 teeth affected to estimate prevalence ratios (PR) by multinomial logistic regression. To test for consistency, means ratio (MR) were estimated using zero-inflated Poisson.

RESULTS

High sugar intake was associated with ≥ 4 teeth affected by periodontal disease (PR = 1.42; 95% confidence interval (CI) = 1.03-1.94; p = 0.030); consistency Poisson analysis reinforced these results (MR = 1.15; 95% CI = 1.03-1.29; p = 0.011).

CONCLUSION

High level of added sugar intake was associated with greater extent of periodontal disease in adolescents.

CLINICAL RELEVANCE

High sugar intake was associated with periodontal disease in adolescents, supporting the integrated hypothesis of dental caries and periodontal disease and giving impetus to future clinical investigation on the effect of restriction of added sugar consumption in periodontal parameters, which potentially may change traditional treatment protocols of periodontal disease.

Alteration of cytokines in saliva of children with caries and obesity

Caries and obesity are multifactorial diseases with inflammatory components, whose processes involve cells and molecules, such as cytokines. Therefore, the objective of this work was to compare the concentrations of IL-6, IL-8, IL-15, and IL-18 in the salivary samples of children with caries and obesity. The study was carried out with 80 children: 43 with a normal weight and 37 with obesity. The diagnosis of caries was carried out using the ICDAS system. Salivary samples were used to measure the cytokine levels via the ELISA technique. Our results show that children with obesity and dental cavities have high levels of IL-6 and IL-15. Similarly, obese children have elevated levels of these two cytokines, while children with cavitated carious lesions presented alterations in their concentrations of IL-6 and IL-8. In conclusion, our data suggest that IL-6 has a significant effect on both obesity and caries, although IL-8 is more related to caries, and IL-15 is more related to obesity.

Integrated hypothesis of dental caries and periodontal diseases

This review considers an integrated hypothesis of dental caries and periodontal diseases that builds on theoretical ecological principles. The backbone of the hypothesis is based on the dynamic stability stage of the oral microbiota, at which intrinsic (mainly saliva and gingival crevicular fluid) and bacterial (mainly metabolic) resilience factors maintain ecological dynamic stability, compatible with clinical health. However, loss of intrinsic resilience factors and/or prolonged changes in the availability of microbial metabolic substrates may shift the ecological balance of the microbiota into either saccharolytic (acidogenic) or amino acid-degrading/proteolytic (alkalinogenic) stages, depending on the nature of the predominant substrates, leading to clinical diseases. Therefore, to maintain and restore the dynamic stability of the oral microbiota, it is necessary to control the drivers of disease, such as salivary flow and influx of bacterial nutrients into the oral cavity. Contrary to conventional wisdom, excessive intake of fermentable carbohydrates may contribute to inflammation in periodontal tissues resulting from hyperglycaemia. An integrated hypothesis emphasizes that both dental caries and periodontal diseases originate in the dynamic stability stage and emerge in response to nutritional imbalances in the microbiota. Periodontal diseases may belong to the sugar driven inflammatory diseases, similar to diabetes, obesity, and cardiovascular diseases.

Periodontopathogenic microbiota, infectious mechanisms and preterm birth: analysis with structural equations (cohort-BRISA)

PURPOSE

The association between periodontopathogenic microbiota and preterm birth (PTB) has been overly studied. However, the biological mechanisms involved are little known. The objective is to evaluate the effect of periodontopathogenic bacteria burden (PBB), periodontal disease and other infections during pregnancy on preterm birth (PTB), through Structural Equation Modeling.

METHODS

This was a case-control study nested in a prospective cohort called BRISA, including 330 pregnant women, 110 cases and 220 controls. This study included the following variables: cytokines interleukin-10 (IL-10) and transforming growth factor beta (TGF-β), periodontal disease, PBB, age, socioeconomic status (SES), systemic infections and PTB. The correlations between variables were analyzed using Standardized Coefficient (SC).

RESULTS

Greater PBB interfered positively with the occurrence of periodontal disease (SC: 0.027; p: 0.011), but these were not associated with the cytokines studied, nor with PTB. The lower serum levels of IL-10 (SC - 0.330; p 0.022) and TGF-β (SC - 0.612; p  < 0.001), and the presence of other systemic infections during pregnancy (SC 0.159; 0.049) explained the higher occurrence of PTB.

CONCLUSION

It is possible that only the more severe periodontal disease and other systemic infections are capable of altering the cascade of cytokines regulating the inflammatory process and have an effect on the occurrence of PTB.

The occurrence of periodontal diseases and its correlation with different risk factors among a convenient sample of adult Egyptian population: a cross-sectional study

Background: Even though extensive studies on the prevalence of periodontal diseases in various populations worldwide have been carried out, data for the Egyptian population is limited.  The present study was carried out to evaluate the occurrence and the severity of periodontal disease and its correlation with different risk factors. Methods: Periodontal examination was performed on 343 adults attending the outpatient clinics of the Faculty of Dentistry, Cairo University, as well as three private clinics. Socio-demographic data, brushing frequency, body mass index (BMI) and dietary habits were recorded using a questionnaire. Results: It was found that 58.9% of participants had calculus deposits. The occurrence of periodontitis was 89.8%, where 70.8% of participants had stage I and 15.2% had stage II, while only 4.4% and 2.05% suffered from stage III and stage IV, respectively. Calculus was positively correlated with age, grains, and sugar in drinks and negatively correlated with socioeconomic status, education level, brushing frequency and milk. Calculus was not correlated with gender and BMI. Periodontitis was positively correlated with age, carbohydrates other than bread, grains, and crackers, as well as caffeinated drinks, while negatively correlated with gender, socioeconomic status, brushing frequency. Periodontitis was not correlated with BMI or education level. Conclusion: The present study clarifies that age, brushing frequency, carbohydrates and caffeinated drinks consumption are significant factors influencing the occurrence and the severity of periodontal diseases.
