RESUMO
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.

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.
RESUMO
OBJECTIVE: To evaluate cytokine levels of interleukin (IL)-1ß, IL-4, IL-6, IL-17a, tumor necrosis factor (TNF)-α, and interferon (IFN)-γ in the gingival crevicular fluid (GCF) of periodontal sites in individuals with Down syndrome (DS) and analyze their relationship with clinical periodontal parameters. MATERIALS AND METHODS: A cross-sectional study was conducted with 49 DS patients and 32 individuals without DS (non-DS group). Periodontal probing depth (PPD), clinical attachment level (CAL), bleeding on probing (BoP), and visible plaque index (VPI) were evaluated. The periodontal sites were classified as shallow, moderate, and deep. GCF was collected in all shallow sites and, when present, in moderate and deep sites for the analysis of cytokine levels. The cytokines, IL-1ß, IL-4, IL-6, IL-17a, TNF-α, and IFN-γ, were quantified using the Luminex® automatic analyzer system. RESULTS: The DS group presented greater severity of periodontitis compared to the non-DS group (P = 0.005). The DS group showed a significant direct correlation of IL-1ß and an inverse correlation of IFN-γ and IL-14 with all periodontal variables. In the analysis stratified by periodontal pocket depth, we observed a higher level of IFN-γ, IL-17a, IL-1ß, and IL-6 in the shallow sites, and IL-17a, IL-1ß, and IL-6 in deep pockets of DS group individuals. Multivariate models showed that higher levels of IL-1ß, IL-4, IL-6, and IL-17a were associated with Down syndrome even after adjusting for periodontal status, sex, and age. CONCLUSION: The findings suggest that people with DS have greater periodontal impairment and higher levels of cytokines in GCF, even in sites having clinical periodontal parameters similar to those of individuals without DS. These data reiterate the concept of an altered and less effective immune response in the population with DS in the face of a periodontal microbial challenge. CLINICAL RELEVANCE: Elevated periodontal inflammation burden can be observed with higher cytokine levels in the gingival crevicular fluid of people with Down syndrome, especially IL-1, IL-4, IL-6, and IL-17, regardless of the stage of periodontitis.

BACKGROUND: Dental eruption is part of a set of children´s somatic growth phenomena. The worldwide accepted human dental eruption chronology is still based on a small sample of European children. However, evidence points to some population variations with the eruption at least two months later in low-income countries, and local standards may be useful. So, this study aimed to predict deciduous teeth eruption from 12 months of age in a Brazilian infant population. METHODS: We developed a cross-sectional study nested in four prospective cohorts - the Brazilian Ribeirão Preto and São Luís Cohort Study (BRISA) - in a sample of 3,733 children aged 12 to 36 months old, corrected by gestational age. We made a reference curve with the number of teeth erupted by age using the Generalized Additive Models for location, scale, and shape (GAMLSS) technique. The explanatory variable was the corrected children´s age. The dependent variable was the number of erupted teeth, by gender, evaluated according to some different outcome distributional forms. The generalized Akaike information criterion (GAIC) and the model residuals were used as the model selection criterion. RESULTS: The Box-Cox Power Exponential method was the GAMLSS model with better-fit indexes. Our estimation curve was able to predict the number of erupted deciduous teeth by age, similar to the real values, in addition to describing the evolution of children's development, with comparative patterns. There was no difference in the mean number of erupted teeth between the sexes. According to the reference curve, at 12 months old, 25% of children had four erupted teeth or less, while 75% had seven or fewer and 95% had 11 or fewer. At 24 months old, 5% had less than 12, and 75% had 18 or more. At 36 months old, around 50% of the population had deciduous dentition completed (20 teeth). CONCLUSION: The adjusted age was an important predictor of the number of erupted deciduous teeth. This outcome can be a variable incorporated into children's growth and development curves, such as weight and height curves for age to help dentists and physicians in the monitoring the children's health.

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.

OBJECTIVE: Mechanisms underlying the oral outcomes in sickle cell anemia (HbSS) have been less explored. This study aimed to investigate the association of morbimortality indicators and hydroxyurea use with adaptive pulp and jaw bone trabecular changes in HbSS. METHODS: This cross-sectional study included 123 individuals with HbSS. The exposures were the morbimortality indicators of HbSS (number of vaso-occlusive crises, organ damage, hemoglobin level, and leukocyte count) and the use of hydroxyurea for HbSS treatment. The outcomes were adaptive pulp and jaw bone trabecular changes confirmed by radiographic examination. Associations were estimated by Poisson regression in crude and adjusted analyses for sex, skin color, socioeconomic class, and age. RESULTS: The vaso-occlusive crises (mean ratio (MR) = 3.5, p = 0.045), lower hemoglobin (MR = 2.4, p = 0.037), and higher leukocyte count (MR = 2.17, p = 0.036) were risk factors, while the use of hydroxyurea was inversely associated with adaptive pulp changes (MR = 0.23, p = 0.024). The vaso-occlusive crises were associated with jaw bone trabecular changes (MR = 1.33, p = 0.02). CONCLUSION: Adaptive pulp changes may be a potential clinical marker of chronic vasculopathy in HbSS. The use of hydroxyurea may reduce the frequency of adaptive pulp changes.

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.
RESUMO
OBJECTIVES: Periodontitis is a non-communicable disease (NCD) that may be linked to other NCDs through shared risk factors. Accordingly, we analyzed the relationship between periodontitis and behavioral and metabolic risks common to NCDs in Brazilian adults over three decades. METHODS: Indicators of periodontitis, behavioral risks (smoking, alcohol use, sugar-sweetened beverages (SSB), and physical activity), and metabolic risks (overweight/obesity, dyslipidemia, hyperglycemia, and hypertension) in Brazilian adults (25-49 y-old) between 1990 to 2019 were obtained from the Global Burden of Disease Study 2019. Data were adjusted for Gini index. Fixed-effects and Prais-Winsten regressions were performed (p < 0.05). RESULTS: The prevalence of periodontitis has increased among Brazilians since 2005. High-SSB diet, alcohol use, and metabolic risks increased between 1990-2019, whereas smoking decreased. In crude models, periodontitis prevalence increased with alcohol use (2545.1; 95%CI: 2307.9-2782.3), high-SSB diet (365.5; 95%CI: 322.5-408.4), low physical activity (1784.4; 95%CI: 763.7-2805.0), overweight/obesity (172.3; 95%CI: 156.3-188.4), dyslipidemia (734.5; 95%CI: 624.7-844.2), and hyperglycemia (1774.3; 95%CI: 1555.9-1992.7). After adjustment for the Gini index, periodontitis prevalence raised with a high-SBB diet (1416.0; 95%CI: 1120.2-1711.8), overweight/obesity (629.9; 95%CI: 573.1-686.8), dyslipidemia (2035.8; 95%CI: 1728.1-2343.5), and hyperglycemia (8918.1; 95%CI: 7979.8-9856.3). CONCLUSIONS: Periodontitis has increased in Brazil since 2005, despite the smoking reduction. Sugar-sweetened beverage was the behavioral risk that mostly accompanied the periodontal trend. CLINICAL RELEVANCE: Our results support upstream strategies targeting commercial, social, political, and structural determinants to tackle NCDs and reduce oral health inequities.

AIM: To investigate the association between increased serum markers of iron (ferritin and transferrin saturation) and the severity and extent of periodontitis in post-menopausal (PM) women. MATERIALS AND METHODS: Data from 982 PM women participating in NHANES III were analysed. Exposures were high ferritin (≥300 µg/ml) and transferrin saturation (≥45%). The primary outcome was moderate/severe periodontitis defined according to Centers for Disease Control and Prevention and the American Academy of Periodontology. The extent of periodontitis was also assessed as outcome: proportion of sites affected by clinical attachment loss ≥4 mm and probing depth ≥4 mm. Crude and adjusted prevalence ratio (PR) and mean ratio (MR) were estimated using Poisson regression. RESULTS: The prevalence of moderate/severe periodontitis was 27.56%. High ferritin was associated with moderate/severe periodontitis in the crude (PR 1.55, p = .018) and in the final adjusted model (PR 1.53, p = .008). High ferritin and transferrin saturation levels were associated with a higher proportion of sites with clinical attachment loss ≥4 mm (p < .05). CONCLUSIONS: The increasing serum iron markers seem to contribute to periodontitis severity and extent in PM women.

AIM: To investigate pathways between unhealthy and healthy dietary patterns and periodontitis in adolescents (18-19 years of age). MATERIALS AND METHODS: This population-based study (n = 2515) modelled direct and mediated pathways (via biofilm and obesity) from patterns of healthy diet (fruits, fibre, vegetables, and dairy) and unhealthy diet (sugars, snacks, and salty/fast foods) with initial periodontitis (bleeding on probing [BoP], probing depth [PD] ≥ 4 mm, clinical attachment loss [CAL] ≥ 4 mm), moderate periodontitis (BoP, PD ≥ 5 mm, and CAL ≥ 5 mm), and European Federation of Periodontology and the American Academy of Periodontology (EFP-AAP) periodontitis definitions, adjusting for sex, socio-economic status, smoking, and alcohol, through structural equation modelling (α = 5%). RESULTS: Higher values of healthy diet were associated with lower values of initial periodontitis (standardized coefficient [SC] = -0.160; p < .001), moderate periodontitis (SC = -0.202; p < .001), and EFP-AAP periodontitis (p < .05). A higher value of unhealthy diet was associated with higher values of initial periodontitis (SC = 0.134; p = .005) and moderate periodontitis (SC = 0.180; p < .001). Biofilm mediated the association between higher values of unhealthy diet and all periodontal outcomes (p < .05). CONCLUSIONS: Our findings suggest that both healthy and unhealthy dietary patterns may contribute to reduced or increased extent and severity of periodontitis by local and systemic mechanisms, preceding the effect of other established causes such as smoking and obesity, in younger population.

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.

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.
RESUMO
OBJECTIVES: This study aimed to analyse the relationship between adverse pregnancy outcomes (APO) and occlusal traits in the primary dentition, checking for different mediation paths. SETTING AND SAMPLE POPULATION: Children evaluated at birth (T1), between 12 and 24 months (T2), and between 24 and 36 months (T3) were included. Two hundred and seventeen children who participated in T1 and T2 were randomly selected to perform the occlusion examination. MATERIALS AND METHODS: This is a prospective cohort study (BRISA). The theoretical model was tested by structural equation modelling (SEM), estimating standardized coefficients (Coeff.) (α = 0.05). The primary exposure was APO-a latent variable manifested from three health problems at birth: low birthweight (LBW), pre-term birth (PTB) and intrauterine growth restriction (IUGR), evaluated in T1. The outcomes were four different occlusal traits assessed in T3: overjet, anterior and posterior crossbite, and crowding. Each outcome's direct and indirect effects were tested, mediated by growth, breathing, breastfeeding, and pacifier use. RESULTS: There was no direct association between APO and any of the outcomes: overjet (Coeff. = -0.163, P = .241), anterior crossbite (Coeff. = -0.696, P = .065), posterior crossbite (Coeff. = -0.087, P = .589) and crowding (Coeff. = 0.400, P = .423). The indirect (total and specifics) effects tested also showed no association (P > .05). However, APO was associated with lower child growth in all models; breastfeeding was associated with higher child growth in all models, and pacifier use was associated with overjet (Coeff. = 0.184, P < .001) and posterior crossbite (Coeff. = 0.373, P = .011). CONCLUSION: APO was not a risk factor for overjet, crossbite and crowding in an early stage of the primary dentition by direct and indirect pathways. However, growth has been lower in children with APO and higher in children breastfed. Also, the harmful effects of using a pacifier in dental occlusion are highlighted.

AIM: To evaluate the association between low bone mineral density (BMD) and severe periodontitis at the end of the second decade of life. MATERIALS AND METHODS: This population-based study analysed 2032 youngers (18-19 years old) of the RPS cohort. BMD of lumbar spine (BMD-LS) and of the whole body (BMD-WB) were assessed by dual x-ray emission densitometry. Low BMD-LS (Z-score ≤ -2) and low BMD-WB (Z-score ≤ -1.5) were correlated with severe periodontitis. The extent of periodontal disease was also evaluated as the following outcomes: proportions of teeth affected by clinical attachment loss ≥5 mm and probing depth ≥5 mm. Multivariate models by sex, education, family income, risk of alcohol dependence, smoking, plaque, bleeding index, and body mass index were estimated through logistic regression (binary outcomes) and Poisson regression (continuous outcomes). RESULTS: The prevalence of severe periodontitis was 10.97%. Low BMD-LS (odds ratio [OR] = 2.08, confidence interval [CI] = 1.12-3.85, p = .01) and low BMD-WB (OR = 1.34, CI = 1.001-1.81, p = .04) were associated with severe periodontitis in the final multivariate models. Low BMD-LS and BMD-WB were also associated with a greater extent of periodontitis (p < .05). CONCLUSIONS: Low BMD was found to be associated with the severity and extent of periodontitis in adolescents. Adolescents at peak bone mass age presenting low BMD are more likely to be affected by severe periodontitis.

BACKGROUND: This study was conducted to investigate the biological factors underlying the association between pulp necrosis (PN) in subjects with permanent teeth with intact crowns and sickle cell anemia (SCA). METHODS: This cohort study included 140 subjects: 125 without PN and 15 with PN. A theoretical model was built to explore the following biological factors involved in the association between PN and SCA, namely (a) increased number of sickle cell crises in the previous year (No. SCCs/year), (b) low percentage of blood oxygen saturation (SpO2 ) in the body, and (c) comorbidities (CoMs). The theoretical model for testing associations was analyzed by structural equation modeling. RESULTS: PN was associated with CoMs (SFL = 1.115; p = .032) but not with No. SCCs/year (SFL = .127; p = .596) or body SpO2 (SFL = -.102; p = .485). The prevalence rates of osteoarticular lesions (p = .009) and death (p<.001) were significantly higher in subjects with PN than in those without. CONCLUSIONS: Comorbidities, primarily osteoarticular lesions, are associated with PN in permanent teeth with intact crowns of patients with SCA. PN can be considered an indicator of the lethality of SCA.

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-ß), 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-ß (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.

It is unknown whether serum levels of proinflammatory cytokines would be high in children with early childhood caries (ECC). This study investigated the association between serum levels of proinflammatory cytokines and severity of caries in preschoolers younger than 72â¯months. A case-control study was performed with a random sample of 72 children with ECC and 80 caries-free children. The explanatory variables were serum levels of proinflammatory cytokines (IL-6, TNF-α, and NGAL) and the outcome was severity of ECC (number of decayed teeth). Thecrudeanalyses were used toestimate the association between each cytokine and ECC. Then, the analyses were adjusted for socioeconomic factors, excess weight and sugar sweetened beverages consumption using Poisson regression models. The estimated coefficients were expressed as Means Ratio (MR), with 95% confidence intervals (CI). In the crude analyses, the highest tertiles of IL-6 (MRâ¯=â¯1.47, ICâ¯=â¯1.09-2.00, pâ¯=â¯0.012), TNF-α (MRâ¯=â¯1.33, CIâ¯=â¯1.00-1.78, pâ¯=â¯0.040) and NGAL (MRâ¯=â¯2.20, CIâ¯=â¯1.39-3.49, pâ¯=â¯0.001) were associated to ECC. After adjustment, the highest tertiles of IL-6 levels (MRâ¯=â¯1.54, ICâ¯=â¯1.13-2.10, pâ¯=â¯0.005), and NGAL (MRâ¯=â¯1.71, CIâ¯=â¯1.04-2.80, pâ¯=â¯0.032) remained associated to ECC; while TNF-α was no longer associated to ECC (MRâ¯=â¯1.31, CIâ¯=â¯0.98-1.75, pâ¯=â¯0.066). Higher serum levels of proinflammatory cytokines were associated to severity of caries in preschoolers, suggesting that chronic inflammation underlies ECC.

HYPOTHESIS: Proinflammatory cytokines are increased in saliva of mother/children pairs with caries. DESIGN: Case-control study involving caries-free children (nâ¯=â¯20) and children with early childhood caries (ECC) (nâ¯=â¯20), and their mothers (nâ¯=â¯40). The maternal variables analyzed were waist circumference (WC), decayed, missing and filled teeth (DMFT) and sugar intake; and in the children were body mass index (BMI), def-t and sugar intake. Salivary levels of VEGF, IL-6 and TNF-α were analyzed of mother/children pairs. RESULTS: In the mothers, salivary VEGF levels were correlated with DMFT (râ¯=â¯0.35; pâ¯=â¯.03), WC (râ¯=â¯0.35; pâ¯=â¯.02), and sugar intake (râ¯=â¯0.32; pâ¯=â¯.04). Higher salivary IL-6 levels were also correlated with maternal DMFT (râ¯=â¯0.45; pâ¯=â¯.004) and WC (râ¯=â¯0.32; pâ¯=â¯.04). In the children, higher salivary VEGF levels were correlated with higher def-t scores (râ¯=â¯0.42; pâ¯=â¯.008). Children with caries had a 63% higher median salivary VEGF and twofold higher mean IL-6 levels compared to caries-free children. Mothers of children with ECC showed higher mean of salivary IL-6 levels compared to those of children without ECC (pâ¯=â¯.03). CONCLUSION: Salivary proinflammatory cytokines are correlated with the severity of caries in the mother-children pair. Obesity and excessive sugar consumption seem to underlie the associations between proinflammatory cytokines and caries in the family environment.

AIM: To investigate the effects of conventional and orthodontic pacifiers on the prevalence of malocclusion (MO) considering frequency, duration, and intensity of the sucking habit. DESIGN: Data were collected at three time-points: birth, T1; (12-24 months old), T2; (24-36 months old), T3 and were divided into three groups: control (GC; 110), without non-nutritive sucking habits; orthodontic pacifiers (GOrth; 55); conventional pacifiers (GConv; 55). A questionnaire was applied. Clinical examination was performed at T3. The groups were compared as to the prevalence and severity of anterior open bite (AOB), accentuated overjet, anterior crossbite, posterior crossbite (PCB). RESULTS: The use of pacifiers was associated with occurrence of MO compared to GC (P < 0.05). Frequency, intensity, and duration of pacifier use was also associated with of MO. There was significant difference in the prevalence of MO between GConv and GOrth for AOB (P = 0.027). Only GConv exhibited higher odds of PCB compared to GC (P = 0.040). The prevalence of MO was significantly higher in pacifiers users (P < 0.001). CONCLUSION: The prevalence of MO was higher among children who used pacifiers. According to a general trend, the use of conventional pacifiers was associated to severe anterior open bite and overjet.

BACKGROUND: A possible association between being overweight or obese and early childhood caries (ECC) remains controversial. AIM: To investigated this association in a developing country testing the confounding effects of socioeconomic factors and frequency of sugar consumption. METHODS: Historical cohort study, 388 children (aged 24-71 months) living in São Luís, Brazil. A theoretical model adjusted according to income, birthweight, and nutritional status at twelve months and frequency of sugar consumption was generated with directed acyclic graphs to analyze this association. Caries were considered a discrete variable in the Poisson regression models; incidence density ratios (IRs) and 95% confidence intervals (95% CIs) were estimated. RESULTS: Being overweight or obese (IR = 1.52; 95% CI: 1.03-2.22) was independently associated with ECC. Being thin or very thin (IR = 1.97; 95% CI: 1.52-2.54), a high frequency of sugar consumption (IR = 1.83; 95% CI: 1.42-2.38), and age (IR = 3.62; 95% CI: 2.58-5.08) were associated with ECC. CONCLUSIONS: Children overweight or obese, as well as children exhibiting being thin/very thin, were associated with ECC independent of socioeconomic variables and a high frequency of sugar consumption.
