Assessment of the impact of toothache, untreated caries and its consequences on the quality of life among poor Brazilian children / Avaliação do impacto da dor de dente, da cárie não tratada e suas consequências na qualidade de vida de crianças brasileiras

Purpose: to evaluate the impact of dental pain and the consequences of untreated dental caries on the quality of life in children of low social-economic status aged from 8 to 10 years old. Materials and Methods: in this cross-sectional study, 230 children were submitted to a clinical examination in which the caries-pufa ratio was measured, afterward, they answered to two questionnaires: one about their quality of life (CPQ8-10) and the other about dental pain. Data were statistically analyzed through Chi-square, Mann-Whitney or Kruskal-Wallis tests to evaluate the association between the variables with impact on children's OHRQoL. To establish the existence of risk factors among variables and impact on OHRQoL a Poisson Regression model was applied. Results: dental caries (p = 0.003; PR 2.39; 95% CI 1.04­1.56), severity of untreated caries (p = 0.008; PR 2.86; 95% CI 1.13­2.00), toothache (p < 0.001; PR 2.31; 95% CI 1.64­3.27) and PUFA + pufa index (p < 0.023; PR 2.68; 95% CI 1.10­1.87) were associated with and were a predictor factor for impact on overall OHRQoL. All of these variables also had an effect over the social welfare subscale (p ≤ 0.001), whereas caries presence was also statistically linked with the emotional wellbeing subscale (p = 0.008) and dental pain with all four subscales (p ≤ 0.001). Conclusion: untreated dental caries' clinical consequences and dental pain exerted a negative influence on the quality of life of schoolchildren analyzed.(AU)

Objetivo: avaliar o impacto da dor de dente e das consequências da cárie não tratada na qualidade de vida de crianças entre 8 e 10 anos com baixos indicadores socioeconômicos. Métodos: neste estudo transversal, 230 crianças escolares foram submetidas a um exame clínico, no qual foram avaliados seus CPO/ceo (Dentes cariados, perdidos e obturados) e PUFA/pufa (Envolvimento pulpar, ulceração, fístula e abscesso). Em um segundo momento, elas responderam a dois questionários: um sobre a qualidade de vida (CPQ8-10) e outro sobre odontalgia. Os dados foram analisados estatisticamente por meio dos testes de Chi-quadrado, Mann-Whitney ou Kruskal-Wallis, para avaliar a associação entre as variáveis e o impacto na qualidade de vida relacionada à saúde oral (QdVRSO) da criança. Para estabelecer a existência de fatores de risco para impacto na QdVRSO entre as variáveis, um modelo de regressão de Poisson foi aplicado. Resultados: a presença de cárie (p = 0,003; RP 2,39; 95% IC 1,04-1,56), a severidade da cárie não tratada (p = 0,008; RP 2,86; 95% IC 1,13-2,00), dor de dente (p < 0,001; RP 2,31; 95% IC 1,64-3,27) e PUFA/pufa (p < 0,023; RP 2,68; 95% IC 1,10- 1,87) foram associados com impacto na QdVRSO, assim como também foram fatores preditores para o impacto na qualidade de vida relacionada à saúde oral. Todas as então citadas variáveis também exerceram efeito sobre a subescala do bem-estar social (p ≤ 0,001), enquanto a presença de cárie esteve estatisticamente conectada com a subescala do bem-estar emocional (p = 0,008) e a dor dentária com todas as subescalas da QdVRSO (p ≤ 0,001). Conclusão: as consequências clínicas da cárie não tratada e a dor dentária exercem uma influência negativa na qualidade de vida das crianças analisadas.(AU)

Lack of association between dietary inflammatory index and low impact fractures in the Brazilian population: the Brazilian Osteoporosis Study (BRAZOS)

Abstract Introduction: Adequate nutrition, including intake of dietary calcium and vitamin D, is important to maintain bone health. Evidence suggests that a deficiency in micronutrients may contribute to bone loss during aging and exert generalized effects on chronic inflammation. Recently, the Dietary Inflammatory Index (DII) was developed to assess the inflammatory potential of individual diets. Our aim was to evaluate the DII in a representative sample and verify its association with low-impact fractures. Methods: Individuals from The Brazilian Osteoporosis Study (BRAZOS) database had their DII calculated. BRAZOS is an important cross-sectional epidemiological study carried out with a representative sample of men and women ≥40 years old. The research was conducted through in-home interviews administered by a trained team. Nutrition Database System for Research (NDSR) software was used to analyze data on the intake of nutrients, which were employed to calculate the DII using Statistical Analysis Software (SAS®) and Statistical Package for the Social Sciences (SPSS®) to assess its association with low-impact fractures. Results: A total of 2269 subjects had their DII score calculated using information from 24-h recall data. Males had lower DII than females (DII = 1.12 ± 1.04 vs DII = 1.24 ± 0.99, p = 0.012). Women taking statins had lower DII (DII = 0.65 ±1.14 vs DII + 1.26 ± 0.98, p = 0.002), indicating a greater potential for diet-related anti-inflammatory effects. Conclusion: Our findings suggest that women might have a pro-inflammatory diet pattern compared to men. However, we did not find any association between DII scores and low-impact fractures.

Impact of malocclusion on oral health-related quality of life among schoolchildren

Abstract The aim of the present study was to evaluate the prevalence and impact of malocclusion on oral health-related quality of life (OHRQoL) among schoolchildren aged 8 to 10 years and their parents in Diamantina, a town in the southeast of Brazil. A cross-sectional study was conducted with a sample of 390 randomly selected children who were subjected to a clinical oral examination. The Dental Aesthetic Index was used to diagnose malocclusion and the need for orthodontic treatment. The Child Perceptions Questionnaire (CPQ (8-10)) was used to evaluate the impact of malocclusion on OHRQoL. The children's parents answered the Brazilian Economic Criterion Questionnaire for the socioeconomic classification. Data analysis involved the nonparametric Kruskal-Wallis test and Spearman's correlation coefficients. The variables were grouped into a hierarchy of categories ranging from distal to proximal determinants. Poisson regression analysis with robust variance was performed at each level to correlate the total CPQ (8-10) score with the independent variables. The prevalence of malocclusion was 78.7%. Crossbite remained significantly associated with a negative impact on OHRQoL (PR = 1.28; 95%CI:1.17-1.39; p < 0.001). The prevalence of malocclusion was high in the sample investigated and exerted a negative impact on OHRQoL.

Dental caries in schoolchildren: influence of inattention, hyperactivity and executive functions

Abstract Attention-deficit/hyperactivity disorder (ADHD) is characterized by inappropriate levels of hyperactivity, impulsivity, and/or inattention. Individuals with ADHD may present limitations with regard to executive functions and performing activities that involve planning and/or attention/concentration. The aim of the study was to investigate the association between dental caries and signs of ADHD in a representative sample of schoolchildren. A representative sample of 851 schoolchildren aged seven to 12 years was randomly selected from public and private schools. Data acquisition involved a clinical dental examination for cavitated permanent and deciduous teeth using the DMFT/dmft indices. Neuropsychological evaluations, including the assessment of intelligence (Raven's Colored Progressive Matrix Test) and executive functions (Corsi Tapping Blocks tests and Digit Span test) were also performed. Parents/caregivers and teachers answered the SNAP-IV Questionnaire for the investigation of signs of inattention and hyperactivity in the family and school environment. Parents/caregivers also answered questionnaires addressing socioeconomic and socio-demographic characteristics. Descriptive analysis of the variables and Poisson regression with robust variance were performed. Parental reports of signs of inattention (PR: 1.28; p < 0.05) and hyperactivity (PR: 1.15; p < 0.05) were associated with a greater occurrence of caries. A better performance on the backward order of the Corsi Tapping Blocks tests (PR: 0.94; p < 0.05) and higher level of mother's schooling were associated with a lower frequency of caries. A better performance on executive function tasks was a protective factor against dental caries, whereas children considered inattentive and/or hyperactive by their parents had a higher prevalence rate of dental caries.

Avaliação de lesões cariosas e biofilme dentário por fluorescência em pacientes portadores da síndrome metabólica submetidos à cirurgia bariátrica: um estudo de coorte prospectivo / Evaluation of caries lesions and dental biofilm by fluorescence, in patients with metabolic syndrome submitted to bariatric surgery: a prospective cohort study

A obesidade e a síndrome metabólica têm aumentado em proporções preocupantes em nível mundial. Além das consequências sistêmicas, a obesidade e suas comorbidades também têm sido relacionadas com a condição bucal. O objetivo deste estudo foi identificar a progressão de lesões cariosas, presença de biofilme dentário, fluxo salivar e presença de saburra lingual em indivíduos eutróficos, sendo avaliados em dois momentos e portadores de síndrome metabólica antes e após a cirurgia bariátrica. A amostra foi constituída por 150 indivíduos, divididos em dois grupos: grupo controle (GC: 75) e grupo obeso (GO: 75), ambos avaliados em T0 e T1, sendo GC 6 meses após a primeira avaliação e GO 6 meses após a cirurgia bariátrica. A avaliação antropométrica dos indivíduos foi realizada por meio do IMC e circunferência da cintura. Os índices ICDAS II e CPOD foram utilizados para avaliar a progressão da cárie dentária. O método de fluorescência verde (QLF- Quantitative Light-induced Fluorescence) avaliou a perda mineral nas superfícies lisas dos dentes e presença de biofilme dentário. O fluxo salivar estimulado foi avaliado em mL/min. O Índice de Saburra Lingual foi utilizado para a avaliação da presença de saburra na língua. Para análise estatística, utilizou-se os testes Qui Quadrado, Exato de Fisher, Mann-Whitney, Kruskal-Wallis e Regressão Logística Múltipla, adotando nível de significância de 5%. Os resultados mostraram que houve diferença significativas entre os grupos, GC apresentou maior número de dentes hígidos (p=0,038) e dentes sem alteração no esmalte (p=0,005) quando comparado ao GO. Ao comparar GC e GO no T1, verificou-se que houve diferença significativa em relação ao CPOD (p<0,0001), dentes restaurados (p<0,0001) e área da lesão (Ws) (p=0,045), sendo as piores condições encontradas encontradas em GO. Observou-se que houve diferença significativa entre a perda mineral e quantidade de biofilme dentário por fluorescência entre os grupos, mas não entre T0 e T1. Diante dos resultados, podese concluir que indivíduos portadores de síndrome metabólica, comparado com os eutróficos, apresentam maior número de lesões cariosas antes e após a cirurgia bariátrica. No presente estudo a cirurgia bariátrica não interferiu na progressão das lesões cariosas, todavia, destaca-se a necessidade de abordagem multiprofissional e contínua, atuando na prevenção de doenças e atenção odontológica.(AU)

Obesity and the metabolic syndrome have increased in alarming proportions at world level. Apart from systemic consequences, obesity and its comorbidities have also been related to the oral condition. The aim of this study was to identify the caries lesion progression, presence of dental biofilm, the salivary flow and tongue coating in eutrophic individuals, being evaluated in two moments and individuals with metabolic syndrome before and after undergoing bariatric surgery. The sample consisted of 150 individuals divided into two groups: Control Group (CG: 75) and Obese Group (OG): 75, both evaluated in T0 and T1; CG being evaluated six months after T0, and EG, 6 months after bariatric surgery. Anthropometric assessment of individuals was made by means of BMI and waist circumference measurement. The ICDAS II and DMFT indices were used for evaluating the progression of dental caries. The Quantitative Light-induced Fluorescence (QLF) method, for evaluating mineral loss on the smooth tooth surfaces and the presence for dental biofilm. The stimulated salivary flow was evaluated in mL/min. The Winkel tongue coating index (WTCI) was used to evaluate the presence of tongue coating. For statistical analysis, the Chi- Square, Fishers Exact, Kruskal-Wallis and Multiple Logistic Regression tests were used, adopting a significance level of 5%. The results showed statistical difference between the groups: CG presented a higher; number of healthy teeth (p=0.038) and teeth without changes in enamel (p=0.005) when compared to OG. When comparing CG and EG after the second evaluation (T1), statistically significant difference was verified in relation to DMFT (p<0.0001), restored teeth (p<0.0001) and lesion area (Ws) (p=0.045), being the worst conditions found in OG. It was observed that there was a significant difference between mineral loss and the quantity dental biofilm by fluorescence between groups, but not between T0 and T1. In view of the results, the authors concluded that patients with metabolic syndrome, compared to eutrophic, have a higher number of caries lesions before and after bariatric surgery. In the present study, bariatric surgery did not influence in caries lesion progression, however, highlights the necessity to a continuous multi professional approach to acting in the prevention of diseases and dental care.(AU)

Maternal risk behavior and caries incidence in children with sickle cell disease

The aim of this study was to analyze the incidence of caries, in relation to maternal risk behaviors and clinical conditions representing different levels of sickle cell disease severity. A total of 295 children aged 6 to 60 months participated in this cohort conducted from August 2007 to December 2008. They were diagnosed and monitored by the referral service of the state. Interviews were made with families to identify sociodemographic variables, and an oral exam was performed to determine dental caries. The SRQ (Self Report Questionnaire) scale was used to diagnose the presence of common mental disorders, and the CAGE (Cut down, Annoyed, Guilty and Eye opener) was applied to determine abusive use of alcohol. The absolute and relative frequencies of the variables of interest were analyzed by Chi-square and Mann-Whitney, with a 5% significance level. The incidence variables were analyzed according to the logistic regression model, with a confidence interval of 95%. Caries incidence (1.98; SD = 4.68) was higher in the HbSS genotype. There was a statistically significant association between caries incidence and both abusive use of alcohol (32.43%, RR = 1.99; 1.05-3.78; 95%CI) and common mental disorders (8.77% RR = 0.37; 0.15-0.93; 95%CI). There was also an association between caries incidence and maternal risk behavior, indicating that the care network should be expanded to include patients with sickle cell disease.

Impact of molar-incisor hypomineralization on oral health-related quality of life in schoolchildren

Abstract This study evaluated the impact of molar-incisor hypomineralization (MIH) on oral health-related quality of life (OHRQoL) according to the perceptions of schoolchildren and their parents/caregivers. This cross-sectional study consisted of a sample of 594 schoolchildren between 11 and 14 years of age and their parents/caregivers who answered the questionnaires CPQ11-14ISF:16 and P-CPQ, respectively. The main independent variable of this study was MIH of the schoolchildren. Experience of dental caries, malocclusion, and socioeconomic status were treated as confounding variables. Statistical analysis used descriptive analysis and Poisson regression with robust variance. The prevalence of MIH was 18.9%. The overall P-CPQ score ranged from 0 to 35 (average = 7.26 ± 6.84), and the overall CPQ11-14ISF:16 score ranged from 0 to 47 (average = 11.92 ± 7.98). Severe MIH was associated with a greater negative impact of the "functional limitation" domain (RR = 1.41; 95%CI = 1.01-1.97), according to parents'/caregivers' perceptions. Severe MIH was associated with a greater negative impact of the "oral symptom" domain (RR = 1.30; 95%CI = 1.06-1.60) and functional limitation domain (RR = 1.42; 95%CI = 1.08-1.86), according to the schoolchildren's perceptions. Schoolchildren with severe MIH had a greater negative impact on the oral symptom and functional limitation domains than those without MIH. According to parents'/caregivers' perceptions, schoolchildren with severe MIH had a greater negative impact on the functional limitation domain than those without MIH.

Factors associated with the development of early childhood caries among Brazilian preschoolers

The aim of this study was to assess the prevalence of early childhood caries (ECC) in children and investigate the influence of sociodemographic variables, quality of oral hygiene and child-related aspects. A cross-sectional study was carried out with 593 children aged three to five years. Data were collected through clinical examinations and interviews with parents. Interviews with parents of the children were conducted to acquire information on sociodemographic aspects, breastfeeding, bottle feeding and harmful oral habits. Statistical analysis involved the chi-square test and the Poisson regression. The prevalence of ECC was 53.6%. The occurrence of ECC was greater among children with unsatisfactory oral hygiene (PR: 2.95; 95% CI: 2.42-3.60) and those from a family with a lower monthly household income (PR: 1.62; 95% CI: 1.24-2.10). In conclusion, unsatisfactory oral hygiene and monthly income exerted an influence on the occurrence of ECC among preschoolers.
