The aims of this literature review are: to depict the main oral diseases that are related to pregnancy; to clarify some of the possible systemic mechanisms that are associated with these changes; and to address issues about oral care during pregnancy. A woman's organs undergo various physiological, neurological, and hormonal changes during pregnancy. Such changes occur gradually and are essential for the development of the fetus, providing what is needed for tissue formation and establishment of reserves for uterine and fetal life. In turn, the oral cavity shows some events during this period. Among the changes most frequently cited in the literature are pyogenic granuloma, gingivitis, and periodontitis. The inflammation of the periodontal tissues due to the formation of the biofilm increases dramatically in size and severity during the course of a normal pregnancy, even without changes in the amount of biofilm present. In addition, a decrease in salivary pH is observed in pregnant women and may lead to an increased incidence of dental caries in this period.

Resumo: Este artigo tem como objetivo descrever os primeiros resultados de dois estudos avaliativos, um sobre a Rede Cegonha e outro sobre o projeto Parto Adequado, denominados, respectivamente, de avaliação da Rede Cegonha e Nascer Saudável, e identificar possíveis melhorias em comparação ao estudo Nascer no Brasil. Ambos os estudos têm desenho seccional, realizados em 2017. O estudo avaliação da Rede Cegonha incluiu todas as 606 maternidades públicas e mistas envolvidas na Rede Cegonha e um total de 10.675 puérperas. O estudo Nascer Saudável incluiu uma amostra de conveniência de 12 hospitais da rede privada e um total de 4.798 mulheres. Os indicadores de atenção ao parto e nascimento avaliados foram: presença de acompanhante, atendimento por enfermeira obstétrica, preenchimento de partograma, uso de métodos não farmacológicos, deambulação, alimentação, uso de cateter venoso periférico, analgesia, posição da mulher para o parto, episiotomia e manobra de Kristeler. Esses indicadores foram comparados aos encontrados no Nascer no Brasil, estudo de base nacional realizado em 2011-2012, antes do início dos dois programas de intervenção. Para as comparações utilizamos o teste do qui-quadrado para amostras independentes e nível de 95% de confiança. Houve um aumento significativo do número de mulheres com acesso à tecnologia apropriada ao parto entre os anos de 2011 e 2017 e redução de práticas consideradas prejudiciais. No setor privado, observou-se também redução nas taxas de cesariana e aumento da idade gestacional ao nascer. Os resultados deste estudo mostram que políticas públicas bem conduzidas podem mudar o cenário da atenção ao parto e nascimento, promovendo a redução de desfechos maternos e neonatais negativos.

Renner AC, da Silva AAM, Rodriguez JDM, Simões VMF, Barbieri MA, Bettiol H, Thomaz EBAF, Saraiva MC. Are mental health problems and depression associated with bruxism in children? Community Dent Oral Epidemiol 2011. © 2011 John Wiley & Sons A/S Abstract –  Objectives:  Previous studies have found an association between bruxism and emotional and behavioral problems in children, but reported data are inconsistent. The objective of this study was to estimate the prevalence of bruxism, and of its components clenching and grinding, and its associations with mental problems and depression. Methods:  Data from two Brazilian birth cohorts were analyzed: one from 869 children in Ribeirão Preto – RP (São Paulo), a more developed city, and the other from 805 children in São Luís – SL (Maranhão). Current bruxism – evaluated by means of a questionnaire applied to the parents/persons responsible for the children – was defined when the habit of tooth clenching during daytime and/or tooth grinding at night still persisted until the time of the assessment. Additionally, the lifetime prevalence of clenching during daytime only and grinding at night only was also evaluated. Mental health problems were investigated using the Strength and Difficulties Questionnaire (SDQ) and depression using the Children’s Depression Inventory (CDI). Analyses were carried out for each city: with the SDQ subscales (emotional symptoms, conduct problems, peer problems, attention/hyperactivity disorder), with the total score (sum of the subscales), and with the CDI. These analyses were performed considering different response variables: bruxism, clenching only, and grinding only. The risks were estimated using a Poisson regression model. Statistical inferences were based on 95% confidence intervals (95% CI). Results:  There was a high prevalence of current bruxism: 28.7% in RP and 30.0% in SL. The prevalence of clenching was 20.3% in RP and 18.8% in SL, and grinding was found in 35.7% of the children in RP and 39.1% in SL. Multivariable analysis showed a significant association of bruxism with emotional symptoms and total SDQ score in both cities. When analyzed separately, teeth clenching was associated with emotional symptoms, peer problems, and total SDQ score; grinding was significantly associated with emotional symptoms and total SDQ score in RP and SL. Female sex appeared as a protective factor for bruxism, and for clenching and grinding in RP. Furthermore, maternal employment outside the home and white skin color of children were associated with increased prevalence of teeth clenching in SL. Conclusions:  Mental health problems were associated with bruxism, with teeth clenching only and grinding at night only. No association was detected between depression and bruxism, neither clenching nor grinding. But it is necessary to be cautious regarding the inferences from some of our results.

BackgroundPreterm birth is the main cause of morbidity and mortality during the perinatal period. Classical risk factors are held responsible for only 1/3 of preterm births and no current intervention has produced an appreciable reduction of this event. It is necessary to explore new hypotheses and mechanisms of causality by using an integrated approach, collaboration among research groups and less fragmented theoretical-methodological approaches in order to detect new risk factors and to formulate more effective intervention strategies.MethodsThe study will be conducted on a convenience cohort of Brazilian pregnant women recruited at public and private prenatal health services. A total of 1500 pregnant women in São Luís, and 1500 in Ribeirão Preto, will be invited for an interview and for the collection of biological specimens from the 22nd to the 25th week of gestational age (GA). At the time of delivery they will be reinterviewed. GA will be determined using an algorithm based on two criteria: date of last menstruation (DLM) and obstetric ultrasound (OUS) performed at less than 20 weeks of GA. Illicit drug consumption during pregnancy will be determined using a self-applied questionnaire and the following instruments will be used: perceived stress scale, Beck anxiety scale, screening for depression of the Center of Epidemiological Studies (CES-D), experiences of racial discrimination, social network and social support scale of the Medical Outcomes Study and violence (Abuse Assessment Screening and violence questionnaire of the WHO). Bacterial vaginosis, urinary tract infection and periodontal disease will also be identified. Neuroendocrine, immunoinflammatory and medical intervention hypotheses will be tested. The occurrence of elective cesarean section in the absence of labor will be used as a marker of medical intervention.ConclusionPsychosocial, genetic and infectious mechanisms will be selected, since there are indications that they influence preterm birth (PTB). The studies will be conducted in two Brazilian cities with discrepant socioeconomic conditions. The expectation is to identify risk factors for PTB having a greater predictive power than classically studied factors. The final objective is to propose more effective interventions for the reduction of PTB, which, after being tested, might subsidize health policies.Electronic supplementary materialThe online version of this article (doi:10.1186/1742-4755-11-79) contains supplementary material, which is available to authorized users.

BackgroundOral cancer is a potentially fatal disease, especially when diagnosed in advanced stages. In Brazil, the primary health care (PHC) system is responsible for promoting oral health in order to prevent oral diseases. However, there is insufficient evidence to assess whether actions of the PHC system have some effect on the morbidity and mortality from oral cancer. The purpose of this study was to analyze the effect of PHC structure and work processes on the incidence and mortality rates of oral cancer after adjusting for contextual variables.MethodsAn ecological, longitudinal and analytical study was carried out. Data were obtained from different secondary data sources, including three surveys that were nationally representative of Brazilian PHC and carried out over the course of 10 years (2002–2012). Data were aggregated at the state level at different times. Oral cancer incidence and mortality rates, standardized by age and gender, served as the dependent variables. Covariables (sociodemographic, structure of basic health units, and work process in oral health) were entered in the regression models using a hierarchical approach based on a theoretical model. Analysis of mixed effects with random intercept model was also conducted (alpha = 5%).ResultsThe oral cancer incidence rate was positively association with the proportion of of adults over 60 years (β = 0.59; p = 0.010) and adult smokers (β = 0.29; p = 0.010). The oral cancer related mortality rate was positively associated with the proportion of of adults over 60 years (β = 0.24; p < 0.001) and the performance of preventative and diagnostic actions for oral cancer (β = 0.02; p = 0.002). Mortality was inversely associated with the coverage of primary care teams (β = −0.01; p < 0.006) and PHC financing (β = −0.52−9; p = 0.014).ConclusionsIn Brazil, the PHC structure and work processes have been shown to help reduce the mortality rate of oral cancer, but not the incidence rate of the disease. We recommend expanding investments in PHC in order to prevent oral cancer related deaths.Electronic supplementary materialThe online version of this article (10.1186/s12885-017-3700-z) contains supplementary material, which is available to authorized users.

This study analyzed racial inequalities in health in 18,684 elderly Brazilians 65 years or older, interviewed in the National Household Sample Survey in 2008 (PNAD 2008), and who reported their color/race as white, brown, or black. Associations were estimated between self-rated health status, functional incapacity, and number of chronic conditions according to crude and adjusted regression analyses (α = 0.01). The majority of the elderly were white (56.2%). In the adjusted analysis, brown color/races was associated with worse self-rated health status (OR = 1.11; 95%CI: 1.03-1.18) and black color/race was associated with more chronic diseases (PR = 1.07; 95%CI: 1.02-1.13). Brown color/race appeared as a protective factor against functional incapacity. When brown and black elderly were combined in one category (“black”), “black” elderly continued to show worse self-rated health status (OR = 1.09; 95%CI: 1.02-1.16) and lower odds of functional incapacity (OR = 0.83; 95%CI: 0.76-0.92). “Black” color/race lost the association with number of chronic diseases. Color/race explained part of the health inequalities in elderly Brazilians, but other socioeconomic variables had a more striking effect.
