RESUMO

The aim of this study was to evaluate the convergence between the domains of the Autoquestionnaire Qualité de Vie Enfant image (AUQUEI) and the Child Perceptions Questionnaire (CPQ8-10) in the mixed dentition. A sample of 676 children aged 8 to 10 years responded to the health-related quality of life (HRQoL) and oral health-related quality of life (OHRQoL) questionnaires using the AUQUEI and the CPQ8-10, respectively. Clinical (dental caries and malocclusion) and socioeconomic variables were assessed. The validity of convergence between scores (total and per domain) of the two instruments was assessed by Spearman correlation analysis, considering that non-zero coefficient values represented a correlation between scores. The median was calculated to compare the scores of each questionnaire relative to the variables, and the nonparametric Mann-Whitney test was applied to determine statistically significant differences between the categories. A weak significant correlation (between 0.30 and 0.50) was observed between the domains and the total scores of instruments (p < 0.05), except for the leisure domain (p > 0.05). Participants with a lower family income had worse HRQoL (p < 0.05), and those with caries and malocclusion experience had worse OHRQoL (p < 0.05). In conclusion, the AUQUEI and CPQ8-10 instruments showed a weak correlation. Income and clinical variables had a negative impact on the AUQUEI and CPQ8-10, respectively.

RESUMO

The scope of this study was to analyze the spatial distribution of malocclusion (MO), estimate the prevalence and evaluate the associated factors in adolescents. It was a study with results of 5,558 adolescents aged 15 to 19 from the São Paulo Oral Health (SB) 2015 survey. The outcome was MO. Sociodemographic aspects, access to dental services, dental caries and tooth loss were the independent variables. A total of 162 municipalities in the state of São Paulo were included and spatial statistics techniques were applied. Hierarchical logistic regression models were performed. The prevalence of MO was 29.3%. There was a spread pattern between the types of MO and positive detachment (p<0,05). Non-white adolescents (OR=1.32, 95%CI: 1.24-1.42), with less years of schooling (OR=1.30, 95%CI: 1.22-1.42), with teeth extracted due to caries (OR=1.40, 95%CI: 1.03-1.88) were more likely to have MO. Adolescent access to dental consultation did not contribute to reducing the chance of developing MO, regardless of whether the dental consultation occurred less (OR=2.02, 95%CI: 1.65-2.47) or more than one year before (OR=1.63, 95%CI: 1.31-2.03). Thus, the occurrence of MO is unequally distributed in the state of São Paulo and associated with sociodemographic conditions, access to consultations and tooth loss due to caries.

O objetivo foi analisar a distribuição espacial da má oclusão (MO) em adolescentes, estimar a prevalência e avaliar os fatores associados. Estudo com dados de 5.558 adolescentes entre 15 e 19 anos de idade do inquérito - SB São Paulo 2015. O desfecho foi a MO. As variáveis independentes foram os aspectos sociodemográficos, acesso aos serviços odontológicos, cárie e perdas dentárias. Foram incluídos 162 municípios do estado de São Paulo e aplicadas técnicas de estatística espacial. Foram realizados modelos de regressão logística hierarquizada. A prevalência de MO foi de 29,3%. Houve um padrão de espalhamento entre os tipos de MO e correlação espacial positiva (p<0,05). Adolescentes não brancos (OR=1,32, IC95%: 1,24-1,42), com menor tempo de estudo (OR=1,30, IC95%: 1,22-1,42) e com dentes extraídos por cárie (OR=1,40, IC95%: 1,03-1,88) tiveram mais chances de apresentarem MO. O acesso dos adolescentes à consulta odontológica não contribuiu para reduzir a chance de apresentar a MO, independentemente de a consulta ao dentista ter ocorrido há menos (OR=2,02, IC95%: 1,65-2,47) ou há mais de um ano (OR=1,63, IC95%: 1,31-2,03). Assim, a ocorrência de MO é desigualmente distribuída no estado de São Paulo, e associada a condições sociodemográficas de acesso à consulta e perda dentária por cárie.

RESUMO

This study aimed to make a longitudinal analysis of interexaminer calibration reproducibility in diagnosing dental caries in posterior teeth, by examiners without previous experience in epidemiological studies. A group of 11 inexperienced examiners underwent theoretical-practical training and calibration assessments, assisted by a standard examiner. An examiner who did not participate directly in the research selected 5-year-old children with and without caries. The D3 diagnostic threshold was used to evaluate dental caries, based on the World Health Organization (WHO) criteria. The initial calibration (baseline) was performed after the theoretical-practical training session, and consisted of examining 20 children; the second calibration occurred three months later, and involved evaluating another 18 children. The interexaminer agreement was obtained by kappa statistics, and by overall percentage agreement. The paired t-test was applied to compare the values for kappa means and overall percentage agreement between the time points studied. At baseline, the values for kappa (> 0.81) and overall percentage agreement (> 95.63%) were considered high. At the 3-month calibration assessment, all the examiners showed some decrease in both kappa (p < 0.0001) and overall percentage agreement (p = 0.0102). The calibration process currently proposed by the WHO is effective. However, reproducibility was not maintained over time for inexperienced examiners evaluating the posterior teeth of 5-year-old children, under epidemiological conditions.

RESUMO

Resumo O objetivo deste estudo foi analisar a literatura científica da área de saúde bucal coletiva quanto ao cálculo, apresentação e discussão do tamanho do efeito em estudos observacionais. A literatura cientifica na área (2015 a 2019) foi analisada quanto: a) informações gerais (periódico e diretrizes aos autores, número de variáveis e desfechos), b) objetivo e coerência com o cálculo amostral apresentado; c) tamanho do efeito (apresentação, medida utilizada e coerência com a discussão dos dados e conclusão). Foram analisados 123 artigos, de 66 periódicos. A maioria dos artigos avaliados apresenta um único desfecho (74%) e não menciona a realização de cálculo amostral (69,9%). Dentre os que realizaram, para 70,3% havia coerência entre o cálculo amostral utilizado e o objetivo. Apenas 3,3% dos artigos mencionam o termo tamanho do efeito e 24,4% não o consideram na discussão dos resultados, apesar de terem calculado. A regressão logística foi a metodologia estatística mais utilizada (98,4%) e o Odds Ratio a medida de tamanho do efeito mais utilizada (94,3%), embora não tenha sido citada e discutida como uma medida de tamanho do efeito na maioria dos estudos (96,7%). Os pesquisadores, em sua maioria, restringiram a discussão dos resultados apenas à significância estatística encontrada nas associações testadas.

Abstract The objective of this study was to analyze the scientific literature in public oral health regarding calculation, presentation, and discussion of the effect size in observational studies. The scientific literature (2015 to 2019) was analyzed regarding: a) general information (journal and guidelines to authors, number of variables and outcomes), b) objective and consistency with sample calculation presentation; c) effect size (presentation, measure used and consistency with data discussion and conclusion). A total of 123 articles from 66 journals were analyzed. Most articles analyzed presented a single outcome (74%) and did not mention sample size calculation (69.9%). Among those who did, 70.3% showed consistency between sample calculation used and the objective. Only 3.3% of articles mentioned the term effect size and 24.4% did not consider that in the discussion of results, despite showing effect size calculation. Logistic regression was the most commonly used statistical methodology (98.4%) and Odds Ratio was the most commonly used effect size measure (94.3%), although it was not cited and discussed as an effect size measure in most studies (96.7%). It could be concluded that most researchers restrict the discussion of their results only to the statistical significance found in associations under study.

RESUMO

BACKGROUND: Mixed dentition determines an important period of occlusion development in childhood. OBJECTIVE: This study aimed to evaluate the aesthetic impact of the midline diastema cut-off point in mixed dentition. DESIGN: A cross-sectional study was performed with 257 children aged 8-10 years in late mixed dentition, with midline diastema of 1-5 mm and normal maxillary overjet. Orthodontic Aesthetic Subjective Impact Score determined the aesthetic impact of the midline diastema. Four quartiles of diastema measurements and impact scores were considered as cut-off points. Receiver Operating Characteristic curves were constructed, and the distances representing the distances to the ideal point were calculated. The Yuden index determined the efficiency of measuring the diastema to assess the aesthetic impact. The Kruskal-Wallis test compared the groups of participants classified according to the diastema cut-off by the sample quartile regarding the impact score. The analyses were performed with a significance level of 5%. RESULTS: There was no significant difference between the four groups of measurement quartiles of the diastema regarding the aesthetic impact (P > .05). CONCLUSIONS: The perception of dental aesthetics in mixed dentition children was not affected by the midline diastema, regardless of the cut-off point.

RESUMO

This intervention follow-up study evaluated anxiety and stress levels and self-perceived happiness of individuals linked to the health field who did not practice Tai Chi and compared these variables before and after practicing this art. One hundred twenty-three participants were subdivided into two groups: G1) Older health professionals (n=41) and G2) Younger pre-university students interested in the health field (n=82). Participants received a 60-minute Tai Chi class. The Perceived Stress Scale (PSS-14) was applied before the practice, and the State-Trait Anxiety Inventory (STAI) and Andrews Face Scale were used before and after the class. Generalized linear models and the Bowker symmetry test were applied for data analysis. 46.3% and 30.5% of participants in G1 and G2 had mild stress levels, and 43.9% and 46.3% had moderate stress levels, respectively. After practicing Tai Chi, both groups presented significantly lower mean anxiety scores. In G1, 31.7% of participants went from moderate to mild anxiety levels after practice, 19.5% from severe to moderate, and 7.3% from severe to mild. In G2, 28.2% of participants went from moderate to mild anxiety levels after practice, 18.3% from severe to moderate, and 6.1% from severe to mild. Furthermore, 100.0% of individuals in G1 and 96.3% in G2 were happy after the class. Tai Chi was effective in reducing anxiety levels and improving self-perceived happiness.
