RESUMO

BACKGROUND AND OBJECTIVES: This study aimed to investigate the association between pain perception and catastrophising at the beginning of orthodontic treatment; and the association between pain during orthodontic treatment and demographic, clinical and other psychological factors. METHODS: A cohort study with 44 patients (28.9 ± 15.05 years old; 25 females and 19 males) under orthodontic treatment with fixed appliances had their pain perception evaluated through a visual analogue scale at baseline (before activation), 6 h, 24 h, 2nd day, 3rd day, 5th day and 7th day after activation. The scores at each evaluation period after the first (T1), second (T2) and third (T3) appointments were compared by analysis of variance. A multivariate Poisson regression analysis verified the association between pain perception and Pain Catastrophising Scale (PCS); and demographic (age, gender), clinical (tooth crowding, tooth loss, analgesic intake and archwire characteristics) and other psychological (dental anxiety and previous negative dental experiences) independent variables (p < .05). RESULTS: Catastrophising (RR = 1.03, 95%CI 1.01-1.05, p = .0001) showed a weak risk of pain perception at T1. The peak of pain occurred 24 h after activation at T1, T2 and T3. Significant higher scores were observed at T1 in comparison to T2 (FT1,T2  = 11.82, p = .005) and T3 (FT1,T3  = 5.09, p = .03). Wire diameter, tooth crowding and single-arch treatment were found as risk factors for pain. Patients without tooth loss had half of the risk of pain perception, while analgesics intake and older patients were also found with a weak protective association. Dental anxiety and negative dental experience were not associated with pain perception. CONCLUSION: Catastrophising has a mild influence on pain perception and only after the first orthodontic activation. Patients with tooth losses, tooth crowding and using thicker archwires are more likely to report pain after orthodontic activations.

RESUMO

Objective: This work aims to report a clinical case that performed the aesthetic rehabilitation of a patient through the integration of different dental specialties (Orthodontics, Periodontics and Dentistry). Case Report: An 18-year-old female patient received compensatory orthodontic treatment for correction of class II malocclusion, overbite and overjet, and interproximal diastema. After orthodontictreatment, a gingivoplasty was performed to remove excess gingival tissue and increase the crown of the teeth, and a frenectomy for the anomalous labial frenulum removal. After periodontal treatment the in-office bleaching was conducted, and the diastema was closed with microhybrid composite resins. Conclusion: It was concluded that multiprofessional planning made possible the aesthetic / functional rehabilitation of the patient.

RESUMO

New paradigms of Brazilian dental education involve orthodontics in the context of generalist professional formation, encouraging the recognition of teaching reality of this discipline in undergraduate courses in dentistry. This article discusses the orthodontics discipline in Brazilian dentistry undergraduate courses to identify the number of semesters offered, nomenclature, insertion model, content format and the performance of clinical practice in undergraduate education and its association with characterization variables of the discipline. Electronic questionnaires were sent to 203 dental schools, 55 public and 148 private, registered to the Federal Council of Dentistry in 2013. The questionnaires were answered by 92 teachers of orthodontics, representing 45.3% of the existing dental undergraduate courses in Brazil: 55.4% of which from private and 44.6% public schools. The findings of this research show that orthodontics teaching is present in all undergraduate courses analyzed, is a predominant and integrated subject in pediatric dentistry, addresses the contents in theoretical and practical form both in the laboratory and clinic, and assists children with deciduous and mixed dentition for diagnosis, prevention and interception of malocclusions. Egressed students are able to recognize orthodontic problems and direct these young patients to treatment. The presence of clinical practice was associated with the variables that denote greater investments of higher education institutions in professors, academic credentials and curricular matrix due to the integrality of the contents and course load distribution for the discipline.

Os novos paradigmas da educação Odontológica no Brasil envolvem a Ortodontia no contexto de formação do profissional generalista, instigando o reconhecimento da realidade educacional desta disciplina nos cursos de graduação em Odontologia. Este artigo aborda a situação do ensino da disciplina de Ortodontia nos cursos de graduação em Odontologia do Brasil, buscando identificar a quantidade de semestres de oferta, nomenclatura, modelo de inserção, formatação dos conteúdos, além da atuação no cenário das práticas clínicas de ensino de graduação e sua associação com as variáveis de caracterização da disciplina. Foram enviados questionários eletrônicos às 203 Faculdades de Odontologia sendo 55 públicas e 148 privadas registradas no Conselho Federal de Odontologia em 2013. Os questionários foram respondidos por 92 professores de Ortodontia, representando 45,3% dos cursos de graduação de Odontologia existentes no Brasil, sendo 55,4% particulares e 44,6% públicas. O ensino de Ortodontia está presente em todos os cursos de graduação analisados, inserido predominantemente como disciplina integrada à Odontologia infantil, abordando os conteúdos de forma teórico prática, tanto em laboratório quanto em clínica, assistindo crianças na dentadura decídua e mista para diagnóstico, prevenção e interceptação das más oclusões, formando egressos aptos a reconhecer os problemas de Ortodontia e encaminhá-los para tratamento. A presença de prática clínica mostrou-se associada às variáveis que denotam maior investimento da instituição de ensino superior no corpo docente e sua titulação e na matriz curricular, pela integralidade dos conteúdos e distribuição de carga horária para a disciplina.

RESUMO

OBJECTIVE:: To identify variables and their effect size on orthodontic treatment time of Class III malocclusion. MATERIAL AND METHODS:: Forty-five Class III malocclusion cases were selected from 2008 patients' records. Clinical charts, cephalometric radiographs, and pre and posttreatment dental casts were evaluated. Age, sex, PAR index at T1 and T2, overjet, missing teeth, extractions, number of treatment phases, missed appointments, appliance breakages, and cephalometric variables SNA, SNB, ANB, Wits, SnGoGn, CoA, CoGn, IMPA, 1.PP were investigated by multiple linear regression analysis and stepwise method at p<0.05. The sample was also divided into two groups: Group 0-2 (patients who had missed two clinical appointments or less) and Group >2 (patients who missed more than 2 appointments), to detect the influence of this data on treatment time and the quality of the treatment (PAR T2). RESULTS:: Average treatment time was 30.27 months. Multiple regression analysis showed that missed appointment (R2=0.4345) and appliance breakages (R2=0.0596) are the only variables able to significantly predict treatment duration. Treatment time for patients who missed more than 2 appointments was nearly one year longer. However, no significant influence on PAR T2 was observed for those patients. CONCLUSION:: Orthodontic treatment duration in Class III patients is mainly influenced by factors related to patient compliance. Patients who missed more appointments did not show worse orthodontic finishing, but longer treatment. No occlusal, cephalometric, or demographic variable obtained before treatment was able to give some significant prediction about treatment time in Class III patients.

RESUMO

INTRODUCTION: The aim of this in vitro study was to compare the elastic properties of the load-deflection ratio of orthodontic wires of different lot numbers and the same commercial brand. METHODS: A total of 40 nickel-titanium (NiTi) wire segments (Morelli Ortodontia™--Sorocaba, SP, Brazil), 0.016-in in diameter were used. Groups were sorted according to lot numbers (lots 1, 2, 3 and 4). 28-mm length segments from the straight portion (ends) of archwires were used. Deflection tests were performed in an EMIC universal testing machine with 5-N load cell at 1 mm/minute speed. Force at deactivation was recorded at 0.5, 1, 2 and 3 mm deflection. Analysis of variance (ANOVA) was used to compare differences between group means. RESULTS: When comparing the force of groups at the same deflection (3, 2 and 1 mm), during deactivation, no statistical differences were found. CONCLUSION: There are no changes in the elastic properties of different lots of the same commercial brand; thus, the use of different lots of the orthodontic wires used in this research does not compromise the final outcomes of the load-deflection ratio.

Introdução: o objetivo deste estudo experimental in vitro foi comparar a as propriedades elásticas da relação carga/deflexão para fios de diferentes lotes de uma mesma marca comercial. Métodos: foram selecionados quarenta segmentos de arcos de níquel-titânio superelástico (NiTi) (Morelli Ortodontia, Sorocaba/SP, Brasil), com diâmetro de 0,016". Os grupos foram ordenados de acordo com os lotes (lotes 1, 2, 3 e 4). Foram utilizados segmentos com 28mm de comprimento da parte reta (extremidades) dos arcos pré-contornados. Os testes de deflexão foram realizados em uma máquina universal de ensaios EMIC, com célula de carga de 5N e velocidade de 1mm/minuto. A força durante a desativação foi registrada nas deflexões de 0,5; 1; 2 e 3mm. O teste de Análise da Variância (ANOVA) foi utilizado para comparar diferenças entre as médias dos grupos. Resultados: na comparação de força dos lotes em um mesmo ponto de deflexão (3, 2 e 1mm), durante a desativação, não houve diferenças estatísticas. Conclusões: não ocorre alteração nas propriedades elásticas em diferentes lotes da mesma marca. Assim, o uso de diferentes lotes dos fios ortodônticos utilizados nesta pesquisa não comprometeu o resultado final da relação carga/deflexão.

RESUMO

A políticas de saúde bucal prévias à implantação do Sistema Único de Saúde (SUS) eram consideradas excludentes e direcionadas para práticas curativas, onde os indicadores mostravam pouca contribuição na melhoria da saúde bucal. A instituição do SUS possibilitou o direcionamento da saúde pública brasileira para ações preventivas, humanizadas e integradas. O objetivo deste estudo foi analisar o perfil do estudante de Odontologia da Universidade Federal do Pará (UFPA) conforme os interesses profissionais e a atuação no SUS. Foi utilizada uma abordagem indutiva, com procedimento estatístico-comparativo e técnica de observação direta extensiva por meio de questionário. A partir do universo amostral de 478 alunos matriculados do 1º ao 10º semestre, extraiu-se uma amostra de 240 alunos (nível de confiança de 95%). Constatou-se que para 93,8% dos alunos, a construção do SUS é dependente da união dos usuários, governo e profissionais interessados na oferta de melhores serviços. Os mesmos afirmam que a formação em Odontologia na UFPA é direcionada para o trabalho no SUS e que a formação em ciências humanas é importante para o exercício profissional. As disciplinas abordadas e atividades práticas desenvolvidas foram consideradas insuficientes para o exercício profissional (AU).

Oral health policies prior to implementation of the Unified Health System (SUS), were considered mutually exclusive and directed to healing practices. Indicators showed little contribution to the improvement of oral health. The SUS institution allowed the direction of Brazilian public health to preventive, humane and integrated actions. The aim of this study was to analyze the profile of the dental student of the Federal University of Pará according with the professional interests and the performance in the SUS. We used an inductive approach with procedure statistical-comparative and extensive direct technique observation through a questionnaire. From the sample universe of 478 students enrolled of 1st to 10th semester, extracted a sample of 240 students (confidence level 95%). It was found that for 93.8% the SUS construction dependent of the union of users, government and professionals interested in offering best services. The students say that training in dentistry at is directed to the work in the SUS and the human sciences are important for professional practice. The subjects addressed and practical activities developed were considered insufficient for professional practice (AU).

RESUMO

O objetivo deste estudo foi determinar a complexidade e necessidade de tratamento ortodôntico através dos Índices DAI e IOTN (DHC) e avaliar as características da oclusão que apresentam relação estatística significativa com os índices, buscando inferir qual índice apresenta-se como a melhor ferramenta para a seleção de pacientes visando à assistência ortodôntica em saúde coletiva. A amostra deste estudo foi composta de 80 modelos de estudo de pacientes que buscaram tratamento ortodôntico. Foram utilizados protocolos internacionalmente reconhecidos para determinação dos índices e um examinador, devidamente calibrado, mediu os modelos segundo os critérios. Os resultados mostraram que mais de 50% dos casos necessitam de tratamento ortodôntico obrigatório de acordo com os índices. As características oclusais mais prevalentes nesta pesquisa foram: apinhamento anterior (47,5%), apinhamento maxilar (<2mm/51,25%), espaçamento segmento anterior (25%) e diastema mediano (<2mm/62,5%) no índice DAI; overjetmaxilar (< 4mm/31,25%) e overjetmandibular estavam presentes (38,75%) no índice IOTN (DHC). De acordo com os critérios avaliados pode-se concluir que os índices avaliados selecionam pacientes indicados para o tratamento ortodôntico com base nos critérios a que se propõem. O DAI é um indicador de necessidade de tratamento que toma como base características estéticas da dentição humana, enquanto o IOTN é um indicador associado às características potencialmente nocivas ao sistema estomatognático. Considerando a perspectiva de seleção de pacientes para tratamento ortodôntico em saúde pública, o IOTN apresenta-se como a ferramenta mais viável, pois seleciona pacientes com condições oclusais mais graves, as quais prioritariamente deveriam ser tratadas...

The aim of this study was to determine the complexity and orthodontic treatment need through DAI and IOTN (DHC) Indexes and testocclusion characteristics that show a significant relationship according to indexes, seeking to infer which of these indexes represented the best tool of patient selection for orthodontic care in public health. The sample of this study was composed of 80 study models of patients, who sought orthodontic treatment. To collect data internationally recognized protocols were used to determine the indexes and an examiner, calibrated for both indexes, measured the models according to the criteria. Results showed that over 50% of cases require orthodontic treatment according to the indexes. The most prevalent occlusal characteristics in this study were anterior crowding (47.5%), mandibular crowding (< 2mm / 51.25% ), anterior segment spacing ( 25%) and midline diastema (<2mm / 62.5 %) in DAI index; maxillary overjet (<4mm/ 31.25% ) and mandibular overjet were present(38.75% ) in IOTN index(DHC). According to the criteria assessed, it is concluded that the indexes assessed select patients referred for orthodontic treatment based on the criteria they propose. DAI is an indicator of treatment need that takes as its basishuman dentition aesthetic characteristics, while IOTN is an indicator associated with potentially harmful characteristics to the stomatognathic system. Considering the patient selection perspective for orthodontic treatment in public health, IOTN presents itself as the most viable tool for selecting patients with more severe occlusal conditions, which should be primarily treated...
