ABSTRACT

Abstract This systematic review aimed to investigate if there is a better interceptive treatment for palatally displaced canines (PDC) in the mixed dentition stage. The PubMed/MEDLINE, CENTRAL, Scopus, and EMBASE databases were searched for randomized clinical trials related to the research topic. The gray literature and reference lists were also assessed. Network meta-analysis was conducted to analyze the effects of different approaches on PDC eruption. The surface under the cumulative ranking area was calculated to rank the treatments. The certainty of the evidence was evaluated using the GRADE approach. Of the 892 eligible studies, 18 were selected for full-text analysis and 9 for meta-analysis, involving 506 participants and 730 PDC, to compare 9 approaches. The proportion of erupted PDC was significantly higher for all interceptive treatments compared with control (no intervention). Furthermore, the proportion of erupted PDC was higher in patients subjected to rapid maxillary expansion (RME) than those who underwent double extraction of primary canine and primary molar (relative risk (RR) = 2.68 ICr95%: 1.12-9.35). A higher proportion of erupted PDC was found for RME (RR = 3.07 ICr95%: 1.31-10.67), RME plus use of transpalatal arch (TA) plus extraction of primary canine(s) (EC) (RR = 1.43 ICr95%: 1.09-1.95), EC plus use of cervical pull headgear (RR = 1.38 ICr95%: 1.11-1.79), and EC plus use of TA (RR = 1.36 ICr95%: 1.00-1.9) than for EC. RME was most likely to be considered as the best interceptive treatment. Overall, the certainty of the evidence was considered low due to imprecision and indirectness. In conclusion, no intervention in the mixed dentition stage is the worst choice for PDC.

ABSTRACT

Case report: This article presents the case of an 11-year-old patient who sought orthodontic treatment, complaining of crooked teeth. In anamnesis, an emotional and physical dependence was reported regarding the act of breastfeeding. Considerations on the diagnosis, psychological implications, and clinical approach in this rare case were addressed. An orthodontic treatment and myofunctional therapy were performed to resolve the occlusal and functional aspects of the patient. Psychological therapy for the child and her mother was required to handle emotional sequelae. Conclusion: Multidisciplinary treatment was prescribed. Dentists should be aware of this need in cases of patients with special characteristics for treatment beyond oral problems. In orthodontics, this may be the difference between effective treatment outcomes or not.


Relato de caso: Este artigo apresenta o caso de uma paciente de 11 anos que procurou tratamento ortodôntico com queixa de "dentes tortos". Na anamnese, foi relatada dependência emocional e física da criança em relação ao ato de amamentar. Considerações sobre diagnóstico, implicações psicológicas, abordagem clínica neste raro caso foram abordadas. Foi realizado tratamento ortodôntico e terapia miofuncional para resolução dos aspectos oclusais e funcionais do paciente. Um acompanhamento psicológico para crianças e sua mãe foi necessária para abordar sequelas emocionais inerentes. Conclusão: Um tratamento multiprofissional foi instituído e o dentista deve estar atento a essa necessidade nos casos de pacientes com características especiais, visando uma abordagem além dos problemas bucais. Na Ortodontia, essa pode ser a diferença entre os resultados eficazes do tratamento ou não.

ABSTRACT

Abstract: This study aimed to develop and validate the Malocclusion Impact Scale for Early Childhood (MIS-EC), a malocclusion-specific measure of oral health-related quality of life (OHRQoL) of children aged 3-5 years and their parents/caregivers. A pool of items was analysed to identify those relevant to the assessment of the impact of malocclusion on OHRQoL. Dental professionals and mothers of children with and without malocclusion rated the importance of these items. The final version of the MIS-EC was evaluated in a cross-sectional study comprising 381 parents of children aged 3-5 years to assess construct validity, internal consistency and test-retest reliability. Twenty-two items were identified from item pooling. After item reduction, eight items were chosen to constitute the MIS-EC, in addition to two general questions. The MIS-EC demonstrated good internal consistency (Cronbach's alpha = 0.79 for the Child Impact section and 0.53 for the Family Impact section), and excellent test-retest reliability (ICC = 0.94), floor effect was 55.7% and ceiling effect 0%. MIS-EC scores indicating worse OHRQoL were significantly associated with the presence of malocclusion (p < 0.05). The MIS-EC is reliable and valid for assessing the impact of malocclusion on the OHRQoL of preschool children and their parents/caregivers.

ABSTRACT

ABSTRACT Objective: To evaluate the skill of orthodontists and oral/maxillofacial surgeons (OMFS) in providing a prognosis of mandibular third molars spontaneously erupted, through follow-up panoramic analysis. Methods: 22 orthodontic patients treated without extraction, presenting spontaneously erupted mandibular third molars (n = 44) were analyzed through panoramic serial radiographs. The first panoramic radiograph was obtained just after orthodontic treatment (PR1), in patients aging from 13 to 19 years. A second panoramic radiograph (PR2), was obtained in average two years later. The radiographs were randomly analyzed by 54 specialists, 27 orthodontists and 27 OMFS, to obtain the opinion about the approach to be adopted to these teeth in PR1. Then, another opinion was collected by adding a serial radiograph (PR1+2). Results: The concordance of the answers was moderate for OMFS (Kappa 0.44; p< 0.0001) and significant for orthodontists (Kappa 0.39; p< 0.0001). In the analysis of the first radiograph (PR1) of the spontaneously erupted molars, OMFS indicated extraction in 44.5% of cases, while orthodontists indicated in 42%, with no difference between groups (p= 0.22). In PR1+2 analysis, orthodontists maintained the same level of extraction indication (45.6%, p= 0.08), while surgeons indicated more extractions (63.2%, p< 0.0001). Conclusions: Orthodontists and OMFS were not able to predict the eruption of the third molars that have erupted spontaneously. Both indicated extractions around half of the third molars. A follow-up analysis, including one more radiograph, did not improve the accuracy of prognosis among orthodontists and worsened for OMFS.


RESUMO Objetivo: Avaliar a habilidade de ortodontistas e cirurgiões bucomaxilofaciais (CBMF) em propor um prognóstico para terceiros molares inferiores. Métodos: Foram analisados 22 pacientes tratados ortodonticamente sem extração, cujos terceiros molares inferiores irrompidos espontaneamente (n= 44) foram avaliados por meio de radiografias panorâmicas seriadas. A primeira radiografia foi obtida logo após o tratamento ortodôntico (RX1), entre 13 e 19 anos de idade. A segunda radiografia (RX2) foi avaliada dois anos depois, em média. As radiografias foram analisadas aleatoriamente por 54 especialistas, 27 ortodontistas e 27 CBMFs, para obter sua opinião sobre a abordagem a ser adotada na RX1. Em seguida, outra opinião foi coletada adicionando-se a segunda radiografia seriada (RX1+2). Resultados: A concordância das respostas foi moderada para os CBMFs (Kappa = 0,44; p< 0,0001) e significativa para os ortodontistas (Kappa = 0,39; p< 0,0001). Após analisar apenas a primeira radiografia (RX1) dos molares antes deles irromperem espontaneamente, os CBMFs indicaram extração em 44,5% dos casos; enquanto os ortodontistas, em 42%, sem diferença entre os grupos (p= 0,22). Na análise de RX1+2, os ortodontistas mantiveram o mesmo nível de indicação de extração (45,6%, p= 0,08), enquanto os cirurgiões passaram a indicar mais extrações (63,2%, p< 0,0001). Conclusões: Ortodontistas e CBMFs não foram capazes de predizer a erupção de terceiros molares por meio da análise de uma única radiografia panorâmica, indicando extrações em cerca da metade dos terceiros molares examinados. Uma análise de acompanhamento, incluindo mais uma radiografia, não melhorou a precisão do prognóstico entre os ortodontistas, e piorou entre os CBMFs.

ABSTRACT

Abstract This study aimed to determine the incidence of mandibular third molar (M3) impaction after orthodontic treatment by edgewise appliances, and identify possible determinant factors of M3 impaction. A retrospective cohort study was conducted with 1154 patients. Complete orthodontic records were analyzed pretreatment and posttreatment, considering the following variables: type of Angle malocclusion, treatment with or without extraction of first premolars, overbite, stage of dentition, M3 prior angulation and duration of orthodontic treatment. Impaction was determined after radiographic evidence of total closure of the root apex. The chi-square test and Poisson regression (p < 0.05) were used for statistical analysis with a hierarchical approach. Rate ratios (RR) and 95% confidence intervals (CI) were calculated. Mandibular M3 impaction incidence was 17%. Overbite equal to or greater than 4 mm (RR = 1.23, 95%CI: 1.11-1.26, p < 0.001), prior mesial angulation of M3 (RR = 0.59, 95%CI: 0.52-0.68, p < 0.001), non-extraction of first premolars (RR=1.06, 95%CI: 1.01-1.12, P=0.019) and orthodontic treatment time equal to or less than three years (RR = 0.94. 95%CI: 0.90-0.99, p < 0.014) were significantly associated with impacted M3. There was no correlation between the type of Angle malocclusion and the risk of impaction. In conclusion, the incidence of mandibular M3 impaction was considered low. The main pretreatment factors directly involved in impaction were mesioangulation of M3 and overbite equal to or greater than 4 mm. Orthodontic treatment with extraction of first premolars and treatment time greater than 3 years reduce the risk of impaction.

ABSTRACT

Aim: This study assessed whether the presence of malocclusion had a negative impact on the oral health-related quality of life (OHRQoL) of eight to ten-year-old children of low socioeconomic status. Methods: A cross-sectional study was conducted with a total of 111 children, eight to ten years of age, randomly selected from public schools from Diamantina, MG, Brazil. The number of children was determined by a sample size calculation. Two calibrated examiners performed clinical oral examinations for the diagnosis of malocclusion, dental caries experience, and traumatic dental injuries following the Dental Aesthetic Index (DAI), the World Health Organization (WHO), and Andreasen's classification, respectively. The Brazilian version of the Child Perceptions Questionnaire (CPQ8-10) was applied to evaluate the OHRQoL. Descriptive and bivariate (p < 0.05) analyses were also performed. Results: Children had a mean age of 8.89 ± 0.82 years, of which 52.3% were female. The prevalence of malocclusion was 62.2%. Significant differences were found in emotional (p = 0.045) and social (p = 0.017) well-being subscale scores as well as in the total CPQ8-10 (p = 0.022) scores between children with and without malocclusion. Conclusion: The presence of malocclusion negatively impacted the OHRQoL of children aged eight to ten years of age of a low socioeconomic status.


Objetivo: Este estudo avaliou se a presença de maloclusão impactou negativamente a qualidade de vida relacionada à saúde bucal (QVRSB) de crianças de oito a dez anos de idade de baixo nível socioeconômico.Métodos: Um estudo transversal foi conduzido com um total de 111 crianças de oito a dez anos de idade selecionadas aleatoriamente em escolas públicas de Diamantina, Brasil. O número de crianças foi determinado por cálculo amostral. Dois examinadores calibrados realizaram exames clínicos bucais para o diagnóstico de maloclusão, experiência de cárie dentária e lesões dentárias traumáticas após o Índice de Estética Dental (DAI), Organização Mundial da Saúde (OMS) e classificação de Andreasen, respectivamente. A versão brasileira do Child Perceptions Questionnaire (CPQ8-10) foi aplicada para avaliar a QVRSB. Foram realizadas análises descritivas e bivariadas (p < 0,05). Resultados: As crianças tinham média de idade de 8,89 ± 0,82 anos, sendo 52,3% do sexo feminino. A prevalência de maloclusão foi de 62,2%. Foram encontradas diferenças significativas nos escores das subescalas de bem-estar emocional (p = 0,045) e social (p = 0,017), como também nos escores totais do CPQ8-10 (p = 0,022) entre crianças com e sem maloclusão. Conclusão: A presença de maloclusão impactou negativamente a QVRSB de crianças de oito a dez anos de idade de baixo nível socioeconômico.

ABSTRACT

Resumo O abuso físico de crianças é definido como qualquer ferida não acidental ou omissão dos seus responsáveis que cause risco à sua integridade. Este estudo objetivou avaliar se profissionais de saúde percebem e denunciam o abuso físico em crianças/adolescentes. Um total de 62 profissionais de saúde (odontólogos, médicos e enfermeiros) de Diamantina/MG, que realizam atendimento a crianças e adolescentes, responderam a um questionário. As variáveis coletadas foram relacionadas à identificação de abuso; denúncia às autoridades e dificuldades para a realização da denúncia. Realizou-se análise de frequência, teste do qui-quadrado e análise de conteúdo. Todos os profissionais relataram ter identificado e denunciado a ocorrência de abuso físico em crianças/adolescentes. Associação significativa foi observada entre a especialidade do profissional e o reconhecimento de abuso, bem como a realização de denúncia às autoridades. As principais dificuldades apresentadas para denunciar os casos às autoridades foram: falta de conhecimento na identificação do abuso e em como realizar a denúncia. A maioria dos participantes gostaria de receber treinamento para identificação e denúncia de abuso. Os profissionais de saúde percebem o abuso infantil, sendo os médicos aqueles que mais denunciam os casos.


Abstract Physical abuse of children is defined as any non-accidental injury or omission of their caregivers that causes risk to the child's integrity. This study aimed to evaluate whether health professionals perceive and report physical abuse in children/adolescents. A total of 62 health professionals (dentists, physicians and nurses) from Diamantina/MG who attend to children and adolescents answered a questionnaire. The collected variables were related to the identification of abuse; denunciation to the authorities and difficulties in making the complaint. Frequency analysis, chi-square test and content analysis were performed. All professionals had identified and reported the occurrence of physical abuse in children/adolescents. Significant association was observed between the specialty of the professional and the recognition of abuse as well as denunciation to the authorities. The main difficulties presented to denounce the cases to the authorities were lack of knowledge in identifying the abuse and how to make the complaint. Most participants expressed that they would like to receive training in identifying and reporting abuse. Health professionals perceive child abuse, and physicians are the ones who most report the cases.

ABSTRACT

ABSTRACT Objective: To assess the impact of two early treatment protocols for anterior dental crossbite on children's quality of life. Methods: Thirty children, 8 to 10 years of age, with anterior dental crossbite, participated in this study. Individuals were divided into two groups: Group 1 - 15 children undergoing treatment with an upper removable appliance with digital springs; Group 2 - 15 children undergoing treatment with resin-reinforced glass ionomer cement bite pads on the lower first molars. Quality of life was evaluated using the Brazilian version of the Child Perceptions Questionnaire (CPQ8-10), which contains four subscales: oral symptoms (OS), functional limitations (FL), emotional well-being (EW), and social well-being (SW). A higher score denotes a greater negative impact on children's quality of life. Children answered the questionnaire before treatment (T1) and twelve months after orthodontic treatment onset (T2). Descriptive statistics, the Wilcoxon test and analysis of covariance (ANCOVA) were performed. Results: Children's mean age was 9.07 ± 0.79 years in Group 1 and 9.00 ± 0.84 years in Group 2. For Group 1, the FL and EW subscale scores and the overall CPQ8-10 were significantly higher in T1 as compared to T2 (p= 0.004, p= 0.012 and p= 0.015, respectively). For Group 2, there were no statistically significant differences. The ANCOVA showed no significant difference regarding quality of life at T2 between groups, after controlling for quality of life measures at T1. Conclusions: The difference regarding the impact on quality of life between groups is not related to the protocol used.


RESUMO Objetivo: avaliar o impacto de dois protocolos de tratamento precoce para a mordida cruzada anterior dentária na qualidade de vida de crianças. Métodos: trinta crianças de 8 a 10 anos de idade com mordida cruzada anterior dentária participaram desse estudo. Os indivíduos foram divididos em dois grupos: Grupo 1 - 15 crianças em tratamento com aparelho removível superior com molas digitais; Grupo 2 - 15 crianças em tratamento com batentes de cimento de ionômero de vidro resinoso nos primeiros molares permanentes inferiores. A qualidade de vida foi avaliada por meio da versão brasileira do Child Perceptions Questionnaire (CPQ8-10), o qual contém quatro subescalas: sintomas bucais (SB), limitações funcionais (LF), bem-estar emocional (BE) e bem-estar social (BS). Um escore mais alto indica um impacto mais negativo na qualidade de vida. As crianças responderam ao questionário antes do tratamento (T1) e 12 meses após o início do tratamento ortodôntico (T2). Estatística descritiva, o teste Wilcoxon e análise de covariância (ANCOVA) foram realizados. Resultados: a média de idade das crianças foi de 9,07 ± 0,79 anos no Grupo 1 e de 9,00 ± 0,84 no Grupo 2. Para o Grupo 1, os escores das subescalas LF e BE e o escore total do CPQ8-10 foram significativamente maiores em T1 do que em T2 (p= 0,004, p= 0,012 e p= 0,015, respectivamente). Para o Grupo 2, não houve diferença estatisticamente significativa. A ANCOVA não mostrou diferença significativa entre os grupos em relação à qualidade de vida em T2, após o controle para as medidas de qualidade de vida em T1. Conclusões: a diferença em relação ao impacto na qualidade de vida entre os grupos não foi relacionada ao protocolo de tratamento utilizado.

ABSTRACT

Abstract The aim of the present study was to confirm the discriminant validity (obtained using traditional statistical methods) of the Early Childhood Oral Health Impact Scale (ECOHIS) between preschool children with and without caries (mean score) through an evaluation of the effect size. A systematic search of electronic databases and a manual search were performed for studies published up to December 2015 involving the use of the ECOHIS for the evaluation of the impact of dental caries on oral health–related quality of life (OHRQoL) among preschool children. Two independent raters performed the selection of the studies and data extraction. Only papers published in English and Spanish were selected. No restrictions were imposed regarding the year of publication. Twelve studies were included, and the magnitude of standardized differences between the means of the “without caries” and “with caries” groups was calculated using Cohen’s d. Most studies demonstrated a large magnitude in the difference between the groups evaluated. The estimate of the effect size confirmed the discriminant validity of the ECOHIS obtained through traditional statistics. Thus, the magnitude of the difference should be considered an important analytical tool for the confirmation of statistical findings regarding null hypotheses and demonstrates the clinical significance of these research results.

ABSTRACT

Abstract Objective: Evidence is contradictory regarding the association between oronasopharyngeal abnormalities and malocclusion. The aim of the present study was to assess the association between oronasopharyngeal abnormalities and malocclusion (anterior open bite and posterior crossbite) in preschoolers. Methods: A cross-sectional study was conducted with a representative sample of 732 preschoolers aged 3-5 years old selected randomly from private and public preschools. Anterior open bite (AOB) and posterior crossbite (PC) were evaluated through a clinical exam. Parents/caregivers answered a questionnaire addressing sociodemographic indicators and oronasopharyngeal issues. Statistical analysis involved descriptive analysis and Poisson regression (p < 0.05). Results: The prevalences of AOB and PC were 21.0% and 11.6%, respectively. Being three years old (PR = 1.244; 95% CI = 1.110-1.394; p < 0.001), being four years old (PR = 1.144; 95% CI = 1.110 - 1.394; p = 0.015), absence of allergy (PR = 1.158; 95% CI = 1.057 - 1.269; p = 0.002), not having undergone nose surgery (PR = 1.152; 95% CI = 1.041 - 1.275; p = 0.006) and having a sore throat more than five times in the same year (PR = 1.118; 95% CI = 1.011 - 1.237; p = 0.030) were significantly associated with AOB. The absence of asthma (PR = 1.082; 95% CI = 1.012 - 1.156; p = 0.020), not having undergone throat surgery (PR = 1.112; 95% CI = 1.068 - 1.158; p < 0.001) and not having undergone nose surgery (PR = 1.114; 95% CI = 1.069 - 1.160; p < 0.001) remained associated with PC. Conclusion: Significant associations were found between oronasopharyngeal-reported abnormalities and the presence of AOB and PC in preschoolers.


resumo Introdução: não há consenso na literatura quanto à associação entre alterações oronasofaríngeas e as más oclusões. Objetivo: o objetivo do presente estudo foi avaliar a associação entre as alterações oronasofaríngeas e as más oclusões (mordida aberta anterior e mordida cruzada posterior) em pré-escolares. Métodos: um estudo transversal foi conduzido com uma amostra representativa de 732 pré-escolares com 3 a 5 anos de idade, aleatoriamente selecionados em pré-escolas privadas e públicas.

ABSTRACT

The aim of this study was to assess periodontal status and bloodparameters in orthodontic patients with nickel allergy one monthafter removal of brackets. Ninety-six randomly selected patientswere initially evaluated. Allergy to nickel was diagnosed using apatch test. After determining the prevalence of subjects allergic tonickel, two groups were formed: 16 allergic (experimental) and 16non-allergic (control) patients. Their periodontal status wasdetermined regularly by a single, blinded, duly calibrated examinerusing the Lõe Index (GI) and their blood was tested (complete bloodtest, including nickel and IgE levels) after nine months oforthodontic treatment and again one month after removing theorthodontic appliances. Statistical analyses included paired andnon-paired t-tests, Mann-Whitney, Wilcoxon, McNemar and lineartrend chi-square tests (p≤0.05). Comparison of the values recordedduring orthodontic treatment and one month after removing theappliances showed that in the allergic group there was significantincrease in eosinophils (p=0.046), basophils (p=0.001) andmonocytes (p=0.002), and decrease in number of bands (p=0.000),while in the control group, there was increase in lymphocytes(p=0.039) and decrease in segmented neutrophils (p=0.030) andIgE levels (p=0.001). In both groups, plasma nickel levels increased(p=0.010; p=0.039) and GI scores decreased. One month afterremoving the brackets, blood and periodontal parameters frompatients with and without nickel allergy were similar.

Noventa e seis pacientesselecionados aleatoriamente foram inicialmente avaliadas. Alergiaao níquel foi diagnosticada usando um teste de contato. Após adeterminação da prevalência de alergia ao níquel, formaram-sedois grupos: 16 pacientes alérgicos (experimental) e 16 nãoalérgicos (controle). Condição periodontal foi diagnosticadaatravés do Índice de Lõe (IG). Parâmetros sanguíneos foramdeterminados por meio de um exame de sangue completo,incluindo a quantificação de níquel e níveis de IgE. Avaliações doestado periodontal foram realizados por um único examinador deforma cega, devidamente calibrado e amostras de sangue foramtomadas depois de nove meses de tratamento e um mês após aremoção dos aparelhos ortodônticos. Análise estatística utilizadafoi testes t pareado e não pareado, Mann-Whitney, Wilcoxon,McNemar e qui-quadrado de tendência linear (p≤0,05). Emcomparação com os valores observados durante o tratamento, onúmero de eosinófilos (p=0,046), basófilos (p=0,001) e monócitos(p=0,002) aumentou significativamente depois da remoção dosaparelhos ortodônticos, ao passo que o número de bastões(p=0,000) diminuiu entre os períodos no grupo alérgico. O númerode linfócitos (p=0,039) aumentou no grupo controle e o número desegmentados (p=0,030) diminuiu. A diminuição dos níveis de IgE(p=0,001) entre os períodos ocorreu no grupo de controle. Níveisde níquel no plasma aumentou após a remoção de aparelhosortodônticos em ambos os grupos (p=0,010; p=0,039). O IGdiminuiu em ambos os grupos. Parâmetros periodontais esanguíneos de pacientes com alergia ao níquel foram semelhantesaos não alérgicos um mês após a remoção dos aparelhos.

ABSTRACT

Objetivou-se com este trabalho avaliar a dinâmica do controle químico de Phakopsora pachyrhizi em plantas de soja submetidas a diferentes regimes hídricos. O experimento foi conduzido na área experimental do Instituto Phytus, no município de Itaara, região central do Rio Grande do Sul, na safra 2012/2013. O delineamento experimental utilizado foi inteiramente casualizado, com quatro repetições, em arranjo fatorial (2x6). O fator A foi composto por dois regimes hídricos: 1) déficit hídrico (50-60% da capacidade de campo); 2) sem déficit hídrico (90-100% da capacidade de campo). O fator B consistiu em quatro intervalos de tempo entre a aplicação de fungicidas e a simulação de chuva (0, 30, 60 e 120 min), uma testemunha com aplicação sem chuva e mais uma testemunha sem aplicação de fungicida. Na aplicação foram utilizados os ingredientes ativos trifloxistrobina + protioconazol (60,0 + 70,0 g i.a.ha-1) com adição de Aureo(r) na dose de 0,375 L.p.c ha-1. Os parâmetros avaliados foram o tempo decorrido entre a aplicação e o surgimento da primeira pústula de ferrugem asiática, a severidade da doença, a produtividade e a massa de grãos. Verificou-se que a aplicação de fungicida em plantas sob déficit hídrico proporciona o maior número de dias para o aparecimento da primeira pústula. A simulação de chuva tem grande efeito na remoção de fungicidas independentemente do regime hídrico. O controle de P. pachyrhizi em plantas sob déficit hídrico foi eficaz, resultando em incrementos de produtividade.(AU)


The objective of this study was to evaluate the dynamics of chemical control of Phakopsora pachyrhizi in soybean plants subjected to different water regimes. The experiment was conducted in the experimental area of Phytus Institute, in Itaara city, central region of Rio Grande do Sul, in 2012/2013 harvest. The experimental design was completely randomized, with four replications in a factorial arrangement (2x6). The first factor was composed of two water regimes: 1) water deficit (50-60% of field capacity); 2) no water deficit (90-100% of field capacity). The B factor was four time intervals between fungicide application and rainfall simulation (0, 30, 60 and 120 min), a witness to application without rain and a control without fungicide application. In application the active ingredients trifloxystrobin + prothioconazole (60.0 + 70.0 g i.a.ha-1) with the addition of Aureo(r) at a dose of 0.375 Lpc ha-1 were used. The parameters evaluated were the number of days until the first pustule preview of Asian rust, disease severity, yield and grain yield. It was found that the fungicide application in plants under water deficit provides the greatest number of days until the first pustule preview. A rainfall simulation has great effect in removing fungicides no matter the water regime. The control of P. pachyrhizi in plants under water deficit was effective, resulting in increased productivity.(AU)

ABSTRACT

The aims of the present study were to compare aspects related to malocclusion between individuals with Down syndrome (DS) and a control group, establish malocclusion severity, and identify determinant factors. A total of 120 individuals (60 with DS and 60 with no physical or mental impairment), were included in the study. Data were collected through interviews, analyses of the medical charts, and oral examinations. The criteria of the Dental Aesthetic Index were used for the diagnosis of malocclusion. Chi-square test (p ≤ 0.05) and multivariate logistic regression were used for comparisons between the two groups and to determine the association between the dependent (malocclusion severity) and independent variables. Statistically significant differences were found between the two groups for the following variables: missing teeth, diastema, overjet, mandibular protrusion, anterior open bite, posterior crossbite, facial type, lip incompetence, and Angle classification. DS, a history of premature birth, and long face pattern were found to be associated with malocclusion severity. Individuals with DS exhibited more occlusal problems than those in the control group.

ABSTRACT

The aim of this study was to evaluate the association between different types of malocclusion and the impact on quality of life among preschoolers and their families. A cross-sectional study was carried out involving 451 children 3-5 years of age. A clinical exam was performed to evaluate the malocclusions according to criteria proposed by Foster and Hamilton. This examination was conducted by a calibrated dentist. Parents/caregivers answered the Early Childhood Oral Health Impact Scale (ECOHIS) for the assessment of Oral Health-Related Quality of Life (OHRQoL) and the questionnaire on socioeconomic and demographic characteristics. Data analysis involved descriptive statistics, chi-square, Mann-Whitney and hierarchically adjusted Poisson regression. The prevalence of malocclusion was 28.4%. The most frequent conditions were posterior crossbite (20.4%), anterior open bite (9.5%) and increased overjet (8.4%). A significant association was found between anterior open bite and OHRQoL (p< 0.001). The adjusted analysis confirmed the association between anterior open bite and a negative impact on quality of life (PR = 2.55; 95%CI: 1.87 to 3.47; p< 0.001). Anterior open bite was associated with a negative impact on the quality of life of preschoolers.

ABSTRACT

OBJECTIVE: The aim of the present systematic review was to determine the existence of scientific evidence demonstrating the effectiveness of orofacial myofunctional therapy (OMT) as an adjuvant to orthodontic treatment in individuals with orofacial disorders. A further aim was to assess the methodological quality of the studies included in the review. METHODS: An electronic search was performed in eight databases (Medline, BBO, LILACS, Web of Science, EMBASE, BIREME, Cochrane Library and SciELO) for papers published between January 1965 and March 2011, with no language restrictions. Selection of articles and data extraction were performed by two independent researchers. The quality of the selected articles was also assessed. RESULTS: Search strategy resulted in the retrieval of 355 publications, only four of which fulfilled the eligibility criteria and qualified for final analysis. All papers selected had a high risk of bias. CONCLUSIONS: The findings of the present systematic review demonstrate the scarcity of consistent studies and scientific evidence supporting the use of OMT in combination with orthodontic treatment to achieve better results in the correction of dentofacial disorders in individuals with orofacial abnormalities. .


OBJETIVO: o objetivo dessa revisão sistemática foi verificar se existem evidências científicas que comprovam a efetividade da TMO como agente coadjuvante do tratamento ortodôntico de indivíduos com distúrbios orofaciais. Além disso, avaliar a qualidade metodológica dos estudos incluídos nessa revisão. MÉTODOS: uma busca eletrônica foi realizada em 8 bases de dados (MEDLINE, BBO, LILACS, Web of Science, EMBASE, BIREME, Cochrane Library e Scielo), sem restrição de idioma. A busca foi realizada com artigos publicados no período compreendido entre janeiro de 1965 a março de 2011. A seleção dos artigos e extração dos dados foi realizada por dois revisores independentes. Avaliação da qualidade dos artigos também foi realizada. RESULTADOS: a estratégia de busca resultou em 355 publicações. Após seleção baseada nos critérios de elegibilidade, quatro artigos foram qualificados para análise final. A todos os artigos incluídos nessa revisão foram atribuídos um alto risco de viés. CONCLUSÇÕES: os resultados do presente estudo demonstram a escassez de estudos consistentes e de evidências científicas que indicam a utilização da TMO em associação ao tratamento ortodôntico com a finalidade de promover melhores resultados na correção de desordens dentofaciais em indivíduos com distúrbios orofaciais. .

ABSTRACT

OBJECTIVE: To investigate the determinant factors of discomfort attributed to the use of fixed orthodontic appliance and the effect on the quality of life of adolescents. MATERIAL AND METHODS : Two hundred and seventy-two individuals aged between 9 and 18 years old, enrolled in public and private schools and undergoing orthodontic treatment with fixed appliance participated in this cross-sectional study. The participants were randomly selected from a sample comprising 62,496 individuals of the same age group. Data was collected by means of questionnaires and an interview. Discomfort intensity and bio-psychosocial variables were assessed using the Oral Impact on Daily Performance questionnaire. Self-esteem was determined using the Global Negative Self-Evaluation questionnaire. Statistical analysis involved the chi-square test and both simple and multiple Poisson regression analyses. RESULTS: Although most individuals did not present discomfort, there was a prevalence of 15.9% of impact on individuals' daily life exclusively due to the use of fixed orthodontic appliance . Age [PR: 3.2 (95% CI: 1.2-8.5)], speech impairment [PR: 2.2 (95% CI: 1.1-4.6)], poor oral hygiene [PR: 2.4 (95% CI: 1.2-4.8)] and tooth mobility [PR: 3.9 (95% CI: 1.8-8.1)] remained independently associated with a greater prevalence of discomfort (P ≤ 0.05). CONCLUSIONS: Discomfort associated with the use of fixed orthodontic appliances exerted a negative influence on the quality of life of the adolescents comprising the present study. The determinants of this association were age, poor oral hygiene, speech impairment and tooth mobility. .


OBJETIVO: investigar os fatores determinantes do desconforto atribuído ao uso do aparelho ortodôntico fixo e sua influência na qualidade de vida de adolescentes. MÉTODOS: participaram desse estudo transversal 272 indivíduos, com idades entre 9 e 18 anos, estudantes de escolas públicas e privadas, que usavam aparelhos ortodônticos fixos (braquetes). Os participantes foram selecionados aleatoriamente, entre 62.496 indivíduos da mesma faixa etária. A coleta de dados foi feita em forma de entrevista e questionário. A intensidade do desconforto e variáveis biopsicossociais foram avaliadas por meio do Oral Impact on Daily Performance (OIDP). A autoestima foi determinada pela Global Negative Self-Evaluation (GSE). A análise estatística envolveu o teste qui-quadrado e a análise de regressão de Poisson, simples e múltipla. RESULTADOS: embora a maioria dos indivíduos não apresentasse desconforto, observou-se uma prevalência de impacto na vida diária devido, exclusivamente, ao uso do aparelho ortodôntico fixo, de 15,9%. Variáveis idade de 15 a 18 anos [RP = 3,2 (IC 95% = 1,2-8,5)], dificuldade de falar [RP = 2,2 (IC 95% = 1,1-4,6)], dificuldade de limpar a boca [RP = 2,4 (IC95% = 1,2-4,8)] e mobilidade dos dentes [RP = 3,9 (IC 95% = 1,8-8,1)] permaneceram associadas, de forma independente, à maior prevalência de desconforto (p ≤ 05). CONCLUSÕES: desconforto associado ao uso de aparelhos ortodônticos fixos influenciou negativamente a qualidade de vida de adolescentes. Os fatores determinantes foram idade, dificuldade de limpar a boca, de falar e mobilidade dentária. .

ABSTRACT

OBJECTIVE: This study aims at assessing the normative need for orthodontic treatment and the factors that determine the subjective impact of malocclusion on 12-year-old Brazilian school children. METHODS: A total of 451 subjects (215 males and 236 females) were randomly selected from private and public schools of Juiz de Fora, Brazil. The collected data included sociodemographic information and occlusal conditions. The esthetic subjective impact of malocclusion was assessed by means of the Orthodontic Aesthetic Subjective Impact Score - OASIS, whereas the malocclusion and the need for orthodontic treatment were assessed by means of the Dental Aesthetic Index (DAI) and the Index of Orthodontic Treatment Need-Aesthetic Component (IOTN-AC). RESULTS: Prevalence of normative need for orthodontic treatment was 65.6% (n = 155), and prevalence of orthodontic esthetic subjective impact was 14.9%. The following variables showed significant association with esthetic subjective impact of malocclusion: female (p = 0.042; OR = 0.5; CI = 0.2-0.9), public school student (p = 0.002; OR = 6.8; CI = 1.9-23.8), maxillary overjet ≥ 4 mm (p = 0.037; OR = 1.7; CI = 1-3) and gingival smile ≥ 4 mm (p = 0.008; OR = 3.4; CI = 1.3-8.8). CONCLUSION: The normative need for orthodontic treatment overestimated the perceived need. Occlusal and sociocultural factors influenced the dissatisfaction of schoolchildren with their dentofacial appearance. .


OBJETIVO: o objetivo desse estudo foi avaliar a necessidade normativa de tratamento ortodôntico e os fatores que determinam o impacto subjetivo da má oclusão, em escolares brasileiros de 12 anos. MÉTODOS: um total de 451 indivíduos (215 homens e 236 mulheres) foi selecionado aleatoriamente de escolas públicas e particulares de Juiz de Fora, Minas Gerais. Os dados coletados incluíam informações sociodemográficas e condições oclusais. O impacto estético subjetivo da má oclusão foi avaliado pelo Orthodontic Aesthetic Subjective Impact Score (OASIS). A avaliação da má oclusão e a necessidade de tratamento ortodôntico foram avaliadas pelo Dental Aesthetic Index (DAI) e pelo Index of Orthodontic Treatment Need-Aesthetic Component (IOTN-AC). RESULTADOS: a prevalência da necessidade normativa de tratamento ortodôntico foi de 65,6% (n = 155) e a prevalência do impacto estético ortodôntico subjetivo foi de 14,9%. As seguintes variáveis mostraram associação significativa com impacto estético subjetivo da má oclusão: sexo feminino (p = 0,042, OR = 0,5, IC = 0,2-0,9); aluno de escola pública (p = 0,002, OR = 6,8, IC = 1,9-23,8); ≥ 4mm (p = 0,037, OR = 1,7; ICI = 1-3); e sorriso gengival ≥ 4mm (p = 0,008, OR = 3,4, IC = 1,3-8,8). CONCLUSÃO: a necessidade normativa de tratamento ortodôntico superestimou a necessidade percebida. Fatores oclusais e socioculturais influenciaram a insatisfação de escolares com a aparência dentofacial. .

ABSTRACT

Objetivo: Comparar os métodos radiográfico, morfométrico e histométrico para avaliação da perdado osso alveolar em ratos com doença periodontal induzida por ligadura e submetidos a estresse crônico.Materiais e Métodos: Ratos Wistar (Rattus norvegicus albinus) machos adultos foram distribuídos emdelineamento inteiramente casualizado em esquema fatorial 2x2 (com e sem doença periodontal (DP), come sem estresse crônico (EC)) com oito repetições em cada grupo. O EC foi realizado por meio de imobilizaçãodiária por 2,5 horas por 30 dias, enquanto que a DP foi induzida com o protocolo de ligadura no primeiro molarmandibular direito e esquerdo nos últimos 14 dias. Após esse período, os ratos foram eutanasiados. Resultados:Na análise radiográfica e histométrica foi determinado o suporte ósseo periodontal (SOP). Adicionalmente,na análise histométrica foi calculada a perda do osso alveolar (POA) e a perda de inserção epitelial (PIE) naface distal do primeiro molar. Na análise morfométrica, a perda do osso alveolar foi obtida pela determinaçãodas distâncias lineares da junção cemento-esmalte (JEC) até crista óssea (CO) no centro das raízes linguaise distais. Observou-se aumento dos níveis de corticosterona (p<0,05) nos animais submetidos a imobilizaçãoe a perda do osso alveolar foi superior (p<0,05) nos animais que receberam a ligadura, independentemente daassociação com estresse, enquanto que a imobilização isoladamente não influenciou esses parâmetros. Houvecorrelação significativa entre as três variáveis utilizadas para avaliação da perda óssea (p<0,05). Conclusão:Métodos histométricos, radiográficos e morfométricos não apresentaram resultados divergentes na avaliaçãoda perda óssea alveolar em ratos com DP e submetidos ao EC.
