RESUMO
INTRODUCTION: There is an inconclusive causal association between asthma symptoms and dental caries in the primary dentition. This study aimed to investigate, using SEM (structural equation modeling), a possible causal relation between asthma and dental caries in the primary dentition. METHODS: Using data from the 2004 Pelotas Birth Cohort Study, a sub-sample of 1,303 individuals was selected. Dental caries was clinically evaluated at 5 years old based on decayed, missing, and filled tooth (dmft) index criteria. Asthma-related symptoms (wheezing and shortness of breath) at 1- and 4-year-olds composed a latent variable and were the main exposures to caries occurrence. SEM was used to identify possible direct, indirect, and mediated effects of asthma in primary dentition dental caries. RESULTS: The general prevalence of caries at age 5 was 1.95 (SD: 3.56). When comparing the dmft values for children with asthma symptoms and those without, they presented similar values in both periods where asthma symptoms were evaluated (1- and 4-year-old). SEM analysis showed that asthma was neither directly nor indirectly related to dental caries. CONCLUSION: Asthma, using a latent variable constructed based on asthma symptoms, showed no causal effect on dental caries occurrence in the primary dentition.

OBJECTIVES: To estimate the socioeconomic disparities in untreated dental caries in early childhood according to socioeconomic characteristics in three birth cohorts in Southern Brazil. METHODS: The socioeconomic data to this study were collected at the 48-month follow-up and oral health studies of 1993, 2004 and 2015 Pelotas birth cohort studies. The outcome was untreated dental caries in children aged 6 (1993 cohort), 5 (2004 cohort) and 4 years (2015 cohort), dichotomized into absence/presence. Analyses were stratified by maternal skin colour/race, maternal education and family income. For statistical purposes, the prevalence difference, relative risk and absolute and relative indices of health inequality (Slope Index of Inequality-SII and Concentration Index-CIX) were used. RESULTS: The prevalence of untreated dental caries in primary dentition was 63.4%, 45.5% and 15.6%, in 1993, 2004 and 2015 cohorts, respectively. The prevalence of untreated dental caries was concentrated in the poorest quintile and lower maternal education group in both absolute (SII) and relative (CIX) measures of inequality, being characterized as a pro-poor event. A higher risk of untreated caries was found in the poorest quintile of family income compared with the richest quintile in the 1993 cohort (RR 1.44 [95% CI 1.05; 1.98]). That risk was higher considering the 2004 Cohort (RR 1.78 [95% CI 1.42; 2.23]) and 2015 cohort (RR 4.20 [95% CI 2.97; 5.94]) data. CONCLUSIONS: Over the course of two decades, a higher prevalence of untreated dental caries is concentrated among the most socioeconomically deprived children.

OBJECTIVES: The understanding of how subjective socioeconomic status (SSS) relates to objective socioeconomic status (OSS), and how both conditions act together in oral health outcomes is still unclear. This study aims to test the independent and joint association between OSS and SSS with oral health, to assess the role of socioeconomic status discrepancies, and to evaluate the role of SSS in the association between OSS and oral health. METHODS: Data from 1140 adults from a population-based study in Southern Brazil were used. We applied diagonal reference models DRM to disentangle the effects of OSS (education) and SSS (MacArthur Scale) to oral health outcomes. The outcomes were functional dentition clinically evaluated (FD ≥20 teeth) and self-reported oral health SROH. We also examined the discrepancy between OSS and SSS to oral health indicators and the effect measure modification (EMM) of SSS on the association between OSS and oral health. RESULTS: Subjective socioeconomic status and OSS contributed equally to SROH, while OSS explained a substantially higher amount of FD than SSS (0.85 vs 0.15). An EMM of SSS was found on the association between OSS and fair/poor SROH, with a relative excess risk due to interaction (RERI) of 1.08. Less evidence of EMM was found for FD (RERI = 0.14). Individuals with lower SSS and OSS had four times the risk of the outcomes than the reference group. CONCLUSIONS: Adults with concordant lower SSS and OSS have a worse oral health than those with concordant higher status. There was evidence that the association between OSS and SROH is modified by SSS.

OBJECTIVES: This cross-sectional study tested the presence of collider bias in the relationship between periodontitis and the carotid intima-media thickness (cIMT). METHODS: Data from 480 members of the 1982 Pelotas Birth Cohort, Brazil, were used. Periodontitis at the age of 24 years was determined as the main exposure. cIMT at the age of 30 years was set as the outcome. High-sensitivity C-reactive protein (hsCRP) was considered the mediator (collider). Confounding variables included sex, income, BMI and smoking. The association between cIMT and periodontitis was tested in conventional logistic regression stratified on hsCRP levels, marginal structural modelling and sensitivity analysis for collider stratification bias. RESULTS: Conventional adjusted logistic regression analysis showed a positive association between periodontitis and cIMT (OR 1.5; 95% CI 1.1; 2.3). Stratified analysis according to the hsCRP levels revealed that the magnitude of the association was even higher among participants with hsCRP ≥ 3 mg/L (OR 2.2, 95% CI 1.1; 4.2) with 36% collider bias probability. No association between periodontitis and cIMT was found among participants with hsCRP < 3 mg/L (OR 1.3; 95% CI 0.8; 2.1). The association was not detected using marginal structural modelling (OR 1.3, 95% CI 0.8; 2.0). CONCLUSIONS: The association between periodontitis and surrogate markers of cardiovascular disease might be induced by collider bias stratification using conventional regression analysis.

BACKGROUND: This study aimed to investigate the association between metabolic syndrome (MetS) and periodontitis among young adults, and also to compare results using observed and latent variables for MetS and periodontitis. METHODS: Data from the 1982 Pelotas Birth Cohort, Brazil, were used. Metabolic syndrome at the age of 23 years was measured using clinical and biochemical analysis and set as the main exposure. Periodontitis at the age of 31 years was clinically measured and set as the outcome. Confounding variables included sex and maternal education, assessed at birth, family income at 23 years, and smoking status at the age of 23 and 30 years. Factor analyses (exploratory and confirmatory) were performed to define latent variables for MetS and periodontitis. In addition, both conditions were also defined as categorical observed variables. The association between MetS and periodontitis was tested in structural equation models. RESULTS: Two latent periodontal variables were identified: "initial" and "advanced" periodontitis, while one latent variable was identified for MetS. Metabolic syndrome is positively associated with "advanced" (coefficient 0.11; P value < 0.01), but not with "initial" (coefficient -0.01; P value = 0.79) periodontitis. When MetS and periodontitis were set as observed variables in the structural equation models, no association was found irrespective of the criteria used for periodontitis classification. CONCLUSIONS: There was a positive association between metabolic syndrome and "advanced" periodontitis, when the multiple dimensions of both diseases were accounted in latent variables. Nevertheless, when MetS and periodontitis were treated as observed variables, no association was detected irrespective of the criteria used for periodontitis classification.

AIM: To investigate the association between depression and periodontitis among adults enrolled in the 1982 Pelotas Birth Cohort, Brazil. MATERIALS AND METHODS: Major depressive episode (MDE) and severity of depressive symptoms obtained in 2012 were considered the exposure of this study. In 2013, periodontitis, the outcome of interest, was clinically assessed and two different case definitions were used: the CDC/AAP and a combination of clinical attachment loss (CAL) and bleeding on probing (BOP) simultaneously. Serum levels of C-reactive protein and frequency of dental flossing were defined as mediators while confounders comprised a set of variables collected throughout the life-course of the participants. The parametric g-formula was used to test the direct, indirect and total effects of depression on periodontitis. RESULTS: 539 participants were clinically examined. Individuals with depressive symptoms presented higher risk of periodontitis (risk ratio [RR] 1.19). The presence of depressive symptoms was also associated with moderate/severe periodontitis (total effect RR 1.18). None of the associations was mediated by flossing or C-reactive protein levels. Finally, neither the presence of depressive symptoms nor the presence of major depression was associated with the combination of CAL+BOP. CONCLUSIONS: A positive association between depressive symptoms and periodontitis and moderate/severe periodontitis was found. MDE was not associated with periodontitis.

OBJECTIVES: This study adopted an intergenerational approach, aiming to answer the following research questions: (a) Are maternal oral health-related behaviours and oral health associated with dental caries in preschool children?; (b) Do maternal caregiving behaviours mediate the association between maternal oral health-related behaviours and dental caries in preschool children. METHODS: Children aged 5 years, enrolled in the 2004 Pelotas (Brazil) Birth Cohort, were investigated (n = 1303). Children were dentally examined using WHO criteria to assess the number of decayed, missing and filled surfaces (dmfs), and their mothers were interviewed. Standardized direct, indirect and total effects of maternal characteristics (frequency of toothbrushing, dental anxiety, the pattern of dental attendance, self-perception about oral health and self-reported dental caries) on maternal caregiving behaviours and children's dmfs were assessed using path analysis. RESULTS: Mean dmfs was 4.1 (95% CI 3.6;4.5). Maternal oral health-related behaviours had no direct effect on children's dental caries: child dental attendance pattern partially mediates the effect of maternal dental attendance pattern on dental caries (87.8%; P < 0.05) and partially mediates the effect of maternal dental anxiety (39.9%; P < 0.001). Child frequency of toothbrushing mediates 28.0% (P < 0.001) of the effect of maternal frequency of toothbrushing on dental caries. CONCLUSIONS: Socioeconomic factors directly influenced children's caries experience, whereas maternal oral health-related behaviours had no direct effect. It was observed an indirect effect of maternal dental anxiety and dental attendance pattern on children's dental caries mediated by caregiving behaviours, such as child dental attendance pattern and frequency of toothbrushing.

AIMS: To quantify the impact of life course income trajectories on periodontitis in adulthood. MATERIALS AND METHODS: Data from the 1982 Pelotas Birth Cohort Study, Brazil, were used. Information on family income was collected at birth and ages 15, 19, 23 and 30 years. Group-based trajectory modelling was used to identify income trajectories. Periodontal measures were assessed through clinical examination at age 31. Log-Poisson regression models were used to estimate prevalence ratios (PRs) of any and moderate/severe periodontitis, as outcomes. RESULTS: Prevalence of any periodontitis and moderate/severe periodontitis was 37.3% and 14.3% (n = 539). Income trajectories were associated with prevalence of moderate/severe periodontitis. Adjusted PR in participants in low and variable income trajectory was 2.1 times higher than in participants in stable high-income trajectory. The unadjusted association between income trajectories and prevalence of any periodontitis was explained by the inclusion of behavioural and clinical variables in the model. CONCLUSIONS: Low and variable life course income increased the prevalence of moderate/severe periodontitis at age 31 years. The findings may inform programmes in identifying and targeting potentially at-risk groups during the life course to prevent periodontitis.

OBJECTIVES: To test whether maternal education has a direct effect on gingival bleeding in adolescents aged 12 and to assess whether oral health behaviours over time mediate that association. METHODS: Two oral health studies nested in the 1993 Pelotas (Brazil) birth cohort study were carried out in participants aged 6 (n = 359) and 12 years (n = 339). The proportion of teeth with bleeding on probing (BOP) and the median number of teeth with gingivitis at age 12 were recorded. Maternal education at birth was the exposure. Toothbrushing frequency and dental visit at ages 6 and 12 years were investigated as mediators of the association between maternal education at birth and gingival bleeding. Time-varying family income through childhood and adolescence was included as later confounder. Paternal education was taken as baseline confounder. The controlled direct effect (CDE) of maternal education at child's birth on gingival bleeding at age 12 was estimated using marginal structural models (MSM). Additionally, path analysis was employed to estimate standardized direct, indirect and total effects of maternal education at birth on gingival bleeding. RESULTS: Adjusted analyses using MSM showed that adolescents whose mothers had <8 years of education had 3.82 higher risk of having teeth with gingival bleeding above the median (rate ratio RR 3.82; 95% CI: 1.68-8.19). Low maternal education doubled the proportion of gingival bleeding at age 12 not mediated by dental visit and toothbrushing frequency (RR 1.99; 95% CI: 1.52-2.60). Path analysis revealed that maternal education had a direct effect on gingival bleeding independently of the mediators. CONCLUSIONS: The pattern of oral health behaviours does not explain the association between mother's education and adolescent's gingival bleeding. Individual-based approaches focused on oral health-related behaviours tend to fail to prevent gingival bleeding.

OBJECTIVES: This study aimed to evaluate the quality of posterior restorations (amalgam or composite) placed in adults from a birth cohort and its association with clinical and socioeconomic determinants experienced during their life course. METHODS: A representative sample (n=539) of all 5914 births occurring in Pelotas (Brazil) in 1982 was prospectively investigated. Quality of posterior restorations (satisfactory or unsatisfactory) was assessed at 31 yrs-old, using modified USPHS criteria. Trained and calibrated dentists performed clinical examination. Explanatory variables included demographic and socioeconomic, oral health and dental service utilization patterns during the life course. Tooth related variables (type of tooth, material, size of cavity) were also analyzed. Untreated caries and socioeconomic status were assessed by group-based trajectories analyses. Multilevel Regression models were used to determine factors associated with restoration outcomes. RESULTS: In total 2123 restorations (53% composite) were evaluated of which 107 (5%) were assessed as failed. The main reasons for failure were tooth/restoration fracture (50.5%) and secondary caries (30.7%). Failures in posterior restorations showed a significant association with socioeconomic aspects (lower tertile of income at age 30 - prevalence ratio (PR) 2.21 [95% CI 1.19-4.09]), clinical variables (trajectory of higher untreated caries - PR 2.11 [95% CI 1.23-3.61]) and also with tooth-related factors (Restorations involving three or more surfaces - PR 5.51 [95% CI 3.30-9.19]) after adjustment for each other. CONCLUSIONS: These findings suggest that, although tooth-related variables have an important role in restoration longevity, patient-related factors, such as socioeconomic variables and untreated caries are also associated with failure and should be taken into account when evaluating longevity of posterior restorations. CLINICAL SIGNIFICANCE: This was the first study assessing long-term trajectory of untreated caries, showing an association between higher experience of caries during the life-course and unsatisfactory restorations. The findings suggest that individual related factors should be considered when planning treatment and in future research evaluating the longevity of dental restorations.

BACKGROUND: Prediction of periodontitis development is challenging. Use of oral health-related data alone, especially in a young population, might underestimate disease risk. This study investigates accuracy of oral, systemic, and socioeconomic data on estimating periodontitis development in a population-based prospective cohort. METHODS: General health history and sociodemographic information were collected throughout the life-course of individuals. Oral examinations were performed at ages 24 and 31 years in the Pelotas 1982 birth cohort. Periodontitis at age 31 years according to six classifications was used as the gold standard to compute area under the receiver operating characteristic curve (AUC). Multivariable binomial regression models were used to evaluate the effects of oral health, general health, and socioeconomic characteristics on accuracy of periodontitis development prediction. RESULTS: Complete data for 471 participants were used. Periodontitis classifications with lower thresholds yielded superior predictive power. Calculus, pocket, or bleeding presence at age 24 years separately presented fair accuracy. Accuracy increased using multivariable models; for example, the Beck et al. classification AUC from 0.59 to 0.75 combining proportion of teeth with calculus, bleeding, or pocket with income; number of lost teeth; sex; education; people living in the house; prosthetic needs; or number of decayed, missing, or filled teeth (DMFT). Proportion of teeth with pocket, bleeding, or calculus; number of DMFT; toothbrushing frequency; blood pressure; sex; and income were most frequently associated. CONCLUSIONS: Choice of classification might have an impact on accuracy to predict periodontitis occurrence. Regardless of the classification, predictive value for development of periodontitis in young adults might be increased by combining periodontal information, sociodemographic information, and general health history.

OBJECTIVES: The aim of this study was to investigate the associated factors of changes in symptoms of xerostomia (SOX) in adults aged 20-59. METHODS: A prospective population-based study was conducted in 2009 (n = 1720) and 2012 (n = 1222) in the urban area of Florianópolis, SC, Brazil. Information on SOX was collected in both years together with age, family income, years of schooling, smoking habit, alcohol consumption, changes in the body mass index (BMI; kg/m²), medicine use, self-reported diagnosis of chronic diseases, change in hypertension status and in the use and need for dentures, and number of remaining teeth. Associated factors with changes in SOX were investigated using multinomial logistic regression, considering those who had never reported this symptom as the reference. RESULTS: Prevalence of regular SOX was equal to 3.8% (95% CI: 2.9-5.1) and irregular (one period only) equal to 12.2% (95% CI: 10.2-14.5). Age, smoking habit, medicine use, self-reported diagnosis of depression, and weight gain increased the probability of regular SOX, whereas highest schooling level was associated with lower probability of this symptom. CONCLUSIONS: General and psychosocial health influenced the number of episodes of xerostomia symptoms, calling for multidisciplinary actions to prevent common risk behaviors for oral and general diseases.

BACKGROUND: The aim of this study is to investigate the effects of abdominal and general obesity on periodontal outcomes in a population-based cohort of Brazilian adults. METHODS: Abdominal and general obesity were assessed in the years 2009 (n = 1,720) and 2012 (n = 1,222). For abdominal obesity, a dichotomous variable was created: 1) eutrophic/lost weight or 2) obese/gained weight. For general obesity, a categorical variable was created: 1) eutrophic/lost weight; 2) gained weight; or 3) obese. Periodontal outcomes were percentage of teeth with bleeding on probing (BOP) and combination of BOP and attachment loss (AL). Hypertension was set as the mediator. Marginal structural models (MSMs) were used to estimate the controlled direct effect of obesity on periodontal outcomes. RESULTS: Periodontal data were presented from 1,066 participants. The total effect model showed those with general obesity in the cohort period presented higher risk of unfavorable periodontal outcomes (rate ratio [RR]: 1.45 for AL and BOP in different teeth; RR: 1.84 for AL and BOP in the same tooth). Estimates from MSMs revealed an effect of general obesity on AL and BOP in different teeth (RR: 1.44). No effect of general obesity was noted on the percentage of BOP. Total effect of abdominal obesity increased risk of AL and BOP in different teeth (RR: 1.47), AL and BOP in the same tooth (RR: 2.77), and percentage of BOP (RR: 1.49). In a MSM, those with abdominal obesity presented greater risk of AL and BOP in the same tooth (RR: 2.16) and percentage of BOP (RR: 1.37). CONCLUSION: Abdominal obesity has a direct effect on unfavorable periodontal outcomes in MSMs.

AIM: This study aimed to conduct a systematic review assessing the effects of weight gain on the incidence of periodontitis in adults. METHODS: Electronic searches in four databases were performed up to and including February 2015. Only prospective longitudinal studies assessing the association between weight gain and the incidence of periodontitis in adults were eligible to be included in this study. All studies should state a clear description of nutritional status (Body Mass Index; Waist Circumference) as well as the case definition of periodontitis. Pooled relative risks (RR) for becoming overweight and obese on the incidence of periodontitis were estimated by meta-analysis. Quality was assessed with the Newcastle-Ottawa scale for cohort studies. RESULTS: Five articles were included in this review and meta-analysis with 42,198 subjects enrolled. Subjects who became overweight and obese presented higher risk to develop new cases of periodontitis (RR 1.13; 95%CI 1.06-1.20 and RR 1.33 95%CI 1.21-1.47 respectively) compared with counterparts who stayed in normal weight. CONCLUSIONS: A clear positive association between weight gain and new cases of periodontitis was found. However, these results are originated from limited evidence. Thus, more studies with longitudinal prospective design are needed.

OBJECTIVE: To assess changes over time of the absolute and relative household income-related inequalities in inadequate dentition (ID) among Australians, Brazilians and USA adults. METHODS: This study used nationwide oral health survey data from Australia (n = 1200 in 1999; n = 2729 in 2005), Brazil (n = 13 431 in 2003; n = 9779 in 2010) and USA (n = 2542 in 1999; n = 1596 in 2005). Absolute income inequalities were calculated using Absolute Concentration Index (ACI) and Slope Index of Inequality (SII), while relative inequalities were calculated using Relative Concentration Index (RCI) and Relative Index of Inequality (RII). RESULTS: Prevalence of ID in the studied period dropped from 8.7% to 3.1% in Australia; from 42.1% to 22.4% in Brazil; and remained stable in USA, nearly 8.0%. Absolute income inequalities were highest in Brazil, followed by the USA and Australia; relative inequalities were lower in Brazil than in Australia and the USA. ID was higher among Brazilian females (2010) and for the poorest group in all countries and periods. A remarkable reduction in absolute inequalities were found in Australia [Slope Index of Inequality (SII) and AIC 60%] and in Brazil (SII 25%; ACI 33%) while relative inequalities increased both in Australia (RCI and RII 40%) and in Brazil (RCI 24%; RII 38%). No changes in absolute and relative income inequalities were found in the USA. CONCLUSION: There were still persistent absolute and relative income inequalities in ID in all examined countries. There has been a reduction in absolute income inequalities in ID but an increase in relative income inequalities.

OBJECTIVE: The objective of this study was to assess the effectiveness of an educational intervention on active commuting by bicycle. METHODS: An intervention study with workers from a metallurgical industry in Santa Catarina state, Brazil was carried out in 2011. A total of 464 individuals were placed in the intervention group (IG) and 468 in the control group (CG). The intervention consisted of strategies based on the transtheoretical model and stages of behavior change. The intervention group took part in activities for 6 months, including 23 meetings. The statistical analysis included intergroup comparison (IG × CG) at baseline and after the intervention. Intragroup analysis was performed 6 months after the intervention. Student's t-test, chi-square, and McNemar tests were used to analyze the data. RESULTS: Of the original total, 876 individuals (94%) participated in the study. The proportion of participants that used bicycles to commute to work (IG) increased significantly from baseline (45.3%) to the final interventional period (47.5%). No difference was found between the CG and the IG group after the interventional period. CONCLUSION: We suggest taking these findings into consideration in further studies to understand better the role of educational intervention on active commuting by bicycle.

OBJECTIVES: This study aimed to evaluate posterior restorations placed in young adults, investigating the association between social determinants experienced during the life course and the quality of tooth fillings. METHODS: A representative sample (n=720) of all 5914 individuals who were born in Pelotas in 1982 was prospectively investigated, and posterior restorations were assessed at 24 years of age. Exploratory variables included demographic and socioeconomic, oral health and dental service payment mode during the life course. Tooth-related variables (type of tooth, material and size of cavity) were also analysed. RESULTS: Multilevel logistic regression models showed that individuals who were always poor from birth to age 23 [odds ratio (OR) 2.35 (1.38-4.00)] and whose mothers had less years of education at their birth (OR 2.60 (1.44-4.68)) were with unsatisfactory restorations in posterior teeth more often. In addition, caries presence at age 15 (high decayed, missing, filled teeth (DMFT) tertile) (OR 1.95 (1.25-3.03)) and cavities with four or more surfaces (OR 18.67 (9.25-37.68)) were associated with the outcome. CONCLUSIONS: These results show that socioeconomic characteristics of the individuals play an important role in restoration failures, reinforcing the need for preventive dental strategies and public policies to reduce inequalities as a major topic of oral health. In addition, the size of cavity appears as the most important determinant for restoration failure. CLINICAL SIGNIFICANCE: Individual socioeconomic characteristics were associated with failure in posterior restorations in detriment of other clinical variables such as restorative material and type of tooth.

OBJECTIVE: The purpose of this study was to investigate the prevalence and identify factors associated with simultaneous risk behaviors for chronic noncommunicable diseases in adults in a southern capital in Brazil. METHOD: A cross-sectional, population-based study was carried out with 1720 adults in Florianópolis, Brazil. The simultaneous occurrence of tobacco smoking, abusive drinking, inadequate or unhealthy diet, and physical inactivity during leisure was assessed. The independent variables were demographic and socioeconomic characteristics. RESULTS: Only 8.3% of the respondents did not have any of these factors, whereas the simultaneous occurrence of two or more risk behaviors was 59.4%. The simultaneous presence of four risk behaviors (3.4%) was 220% higher of what would be expected by combining the individual prevalence of these factors (1.5%). The likelihood of individuals having two or more risk behaviors simultaneously was greater in young men, with black skin color, living without a partner, with lower household per capita income, and lower education. CONCLUSION: It is necessary to implement programs that reduce the risk behaviors for chronic noncommunicable diseases among adults in Brazil, especially between young men with low education and income.

OBJECTIVES: To investigate whether tooth loss is associated with increased blood pressure among adults after controlling for socioeconomic, health, and lifestyle confounders. We also assessed the interactions between tooth loss and smoking status and tooth loss and age on systolic blood pressure (SBP). MATERIAL AND METHODS: A population-based cross-sectional study was carried out with 1720 adults from Florianópolis, Brazil. Data collection included blood pressure, anthropometric measures, and a questionnaire on socio-demographics, self-rated health, diabetes, self-reported number of natural teeth, and dental prosthesis. We used linear multivariable regression models for the association of blood pressure with tooth loss adjusting for potential confounders. RESULTS: Edentulous subjects had a SBP 8.3 mmHg (95% CI 0.1; 16.7) higher than those with more than 10 teeth in both arches after adjustment for potential confounders. We found interaction between tooth loss and smoking status. Moderate/heavy smokers were associated with considerably higher SBP than light, former or non-smokers among edentulous and also partly among dentate with less than 10 teeth in at least one arch, but there was no real association between smoking and SBP among those with 10 or more teeth in both arches. CONCLUSIONS: Total tooth loss is associated with increased levels of SBP in this adult population.

OBJECTIVES: To assess socio-demographic and behavioural inequalities in the impact of dental pain on daily activities, as well as to estimate the prevalence and intensity of dental pain. METHODS: A population-based cross-sectional study was carried out in Florianopolis, Southern Brazil, with 1720 adults aged 20-59 years in 2009-2010. Interviews were performed at adults' households, which included socio-demographics and behavioural characteristics, such as smoking status and alcohol abuse, along with mental health, self-reported health, number of retained teeth, dental pain occurrence (including its intensity and its impact on daily life). The association between the impact of dental pain and the covariates was tested using multinomial logistic regression. RESULTS: The global prevalence of dental pain was 14.8% (95% CI, 12.9-16.7). Adjusted analysis showed that women, those who self-classified as dark-skinned Blacks, those with low family income, current smokers and those with common mental disorders reported a higher impact of dental pain than their counterparts. Among subjects reporting dental pain, 12.7% indicated the maximum intensity, whereas 6.0% had some daily activity disrupted by it, such as difficulties in chewing certain foods (38.0%), sleep disturbance (21.0%), difficulty to work (21.0%) and difficulty in performing household tasks (8.0%). Prevalence ratios of impact of dental pain between the poorest income group and richest income group (2.4), between the highest and lowest schooling group (2.6), and between dark-skinned Blacks and Whites (2.1) were of higher magnitude than the dental pain prevalence ratios among the same groups (1.7, 1.3 and 1.4, respectively). CONCLUSIONS: The impact of dental pain showed a social gradient. Inequalities between socio-economic groups found in this study should be taken into account, as the impact of dental pain leads to reduced daily activities and poor quality of life.
