Background: self-perception data on oral health are important for comprehensive patient's assessment. Objective: to investigate the relationship between parents/caregivers' perceptons on the need of orthodontic treatment in 12-year-old schoolchildren of public schools of Juiz de for a, and associated factors, including access to oral health services. Method: cross-sectional study (n=311). Parents/caregivers answered questions about their perceptions on the need of orthodontic treatment in schoolchildren, socioeconomic level, head of familiy's education level, and access to oral health services. Schoolchildren's normative orthodontic treatment need was assessed tbased on the Dental Aesthetic Index. Schoolchildren also provided their perceptions on the need of orthodontic treatment. Pearson Chi-square, Fisher Exact test or Linear by Linear Association were used for statistical analysis, in addition to logistic regression with significance level p<0.05. Results: normative orthodontic treatment need (p=0.001) and the schoolchildren's perception on their orthodontic treatment need (p<0.001) were statistically associated with parents/caregivers perceptions regarding orthodontic treatment need. Conclusion: Parents/caregivers and children's perceptions on the need of orthodontic treatment were significantly greater than children's normative orthodontic treatment need. [ABSTRACT FROM AUTHOR]

Introdução: Um percentual crescente da população mundial vem tendo acesso ao tratamento ortodôntico ao longo das últimas décadas. Consequentemente, hoje em dia, um maior número de pacientes em busca da correção de suas más oclusões apresenta um histórico de tratamento ortodôntico prévio. Ortodontistas que realizam retratamentos ortodônticos podem enfrentar dificuldades adicionais, e uma delas é ter que lidar com indivíduos que apresentam demandas e expectativas ainda maiores em relação à obtenção de resultados excelentes e de forma bastante eficiente. Objetivos: O presente artigo discute os desafios e os impactos positivos do retratamento ortodôntico causados na autoestima e na qualidade de vida dos pacientes, e ilustra o retratamento em duas fases de uma pré-adolescente, e o retratamento ortodôntico-cirúrgico de uma paciente adulta jovem que tinha demandas muito elevadas para a obtenção de resultados rápidos e excelentes.

Objetivo: Avaliar se o tratamento ortodôntico está associado à presença de desordens temporomandibulares (DTM) em adolescentes e adultos jovens de idade entre 12 e 24 anos. Materiais e métodos: Foi realizada uma investigação sobre sinais e sintomas de DTM aplicando-se o protocolo RDC/TMD (Critérios de Diagnóstico para Pesquisa das Desordens Temporomandibulares), em pacientes ortodônticos e controles. A amostra foi composta por 70 participantes divididos em dois grupos. O grupo ortodôntico foi composto por 35 voluntários em fase ativa de tratamento ortodôntico fixo e o controle por 35 voluntários sem histórico de tratamento ortodôntico. Resultados: Não ocorreram diferenças estatísticas entre os grupos relacionadas ao autorrelato de sintomas de dor de cabeça, dores na face, ruídos articulares e hábitos parafuncionais anteriores ao exame (p > 0,1). Em relação à abertura máxima de boca em milímetros e dor relacionada ao movimento mandibular de abertura também não houve diferença estatística entre os grupos (p > 0,3). No que se refere ao relato de dor à palpação nos músculos masseter e temporal, não ocorreram diferenças estatísticas entre os grupos (p > 0,5). Quanto ao exame das articulações temporomandibulares (ATM), os grupos não diferiram estatisticamente em relação ao relato de dor à palpação, nem quanto à presença de ruídos articulares (p > 0,4). Conclusões: O estudo sugere, portanto, que o uso de aparelho ortodôntico fixo não parece estar associado à presença ou ausência de desordens temporomandibulares em adolescentes e adultos jovens. É recomendável, no entanto, que estudos longitudinais sejam conduzidos aplicando-se o protocolo RDC/TMD.

The mixed dentition, characterized by the replacement of deciduous teeth by permanent, may present some flaws, called dental development anomalies. These anomalies have different degrees of severity that vary from the chronological delay in odontogenesis, to the complete absence of the dental germ, also denominated dental agenesis. This study has the purpose of evaluating the prevalence of second premolar agenesis of the dental complex of Centro Universitário da Serra Gaúcha, as well as compare the results obtained with the world literature and to verify the difference between the sexes. Methods: This research is based on a cross-sectional study which aims to analyze panoramic radiographs of patients attended at FO-FSG in the years from 2015 to 2017 with ages from 10 to 30 years, with the purpose of verifying the prevalence of agenesis of the second premolars. Results: A total of 559 panoramic radiographs were evaluated, from a total of 3,460 registered dental records. In relation to the total prevalence, the following indexes were observed for the male sex: tooth 15 (2,2%), tooth 25 (1,7%), tooth 35 (0,4%) and tooth 45 (0,7%). For females, the indexes were: tooth 15 (1,9%), tooth 25 (1,3%), tooth 35 (1,3%) and tooth 45 (0,7%). Conclusion: The prevalence rate of second premolar agenesis of patients at the dentistry faculty of Centro Universitário da Serra Gaúcha was relatively low, taking into account the number of patients involved, and also did not present a statistically relevant difference between sex and age.

Dental agenesis can be defined as the lack of development of the tooth, with the absence of one to six teeth, being quite frequent in deciduous and permanent dentitions. The etiology is related to genetic as well as environmental factors. The greater the genetic contribution at the origin of an alteration, the less the possibility of preventing, thus, the prognosis of the treatment worse. With early diagnosis, orthodontic intervention can be achieved at an appropriate time. Aim: To evaluate the prevalence of upper lateral incisor agenesis (ILS) in panoramic radiographs of the Faculty of Dentistry of the University Center of Serra Gaúcha, and to compare the results with the world literature in the different sexes, defining the best treatment for occlusal sequelae. Methods: A cross-sectional prevalence study performed at the FO-FSG Radiographic Interpretation Laboratory involved panoramic radiographs performed from 2015 to 2017. Data were recorded on the patient’s medical record number, age, gender, presence or not of agenesia, the absent tooth, the presence or not of diminution of size and presentation of conoid anomaly. Results: In the samples was applied the chi-square test for heterogeneity. It was verified that the genre and the agenesis do not significantly associated, in a statistic view. Conclusion: Individuals with ILS agenesis do not present differences between the sides and genders. It is found that bilateral agenesis of ILS is more frequent than unilateral agenesis.

A anomalia dentária de desenvolvimento mais comum na dentição humana é a agenesia dentária, que pode acontecer nas dentições decídua e permanente. Os dentes mais acometidos pela agenesia são os terceiros molares, pré-molares e incisivos laterais superiores. Comumente está associada a outros tipos de anomalias como a microdontia, ectopias e atraso no desenvolvimento dentário. Portanto, o cirurgião dentista deve se atentar para o desenvolvimento de outras anomalias para que o diagnóstico e a interceptação ortodôntica aconteçam em momento oportuno. Foi realizada uma avaliação das radiografias panorâmicas da documentação de 50 pacientes, selecionados aleatoriamente, com idade entre 6 e 20 anos, de ambos os gêneros, excluindo pacientes sindrômicos, que buscaram tratamento ortodôntico no Curso de Pós-graduação em Ortodontia do Centro Universitário de Volta Redonda. O objetivo desse estudo observacional foi avaliar a presença de agenesia de algum elemento dentário permanente, excluindo os terceiros molares, identificar os dentes mais acometidos, bem como, a associação com outras anomalias dentárias. Avaliando os resultados observou-se que 9 pacientes apresentavam agenesia dentária (18%), com maior prevalência no gênero feminino (55,6%). Os dentes mais acometidos foram os incisivos laterais superiores, seguido dos segundos pré-molares inferiores e segundos pré-molares superiores. A presença de outras anomalias dentárias associadas à agenesia foi identificada em 4 pacientes (44,4%), com predomínio no gênero feminino (75%), que foram o atraso no desenvolvimento dentário, forma conóide, ectopia no posicionamento e dilaceração radicular. Concluiu-se que na amostra estudada houve alta prevalência de agenesia dentária, tendo como referência outros estudos com pacientes ortodônticos.

Este estudo, in vitro, teve como meta medir a influência das cores sobre a degradação da força de elásticos ortodônticos em cadeia da marca Morelli®, após estirados e submersos em saliva artificial. Os valores foram obtidos após mensuração imediata (tempo zero), 30 minutos, 1 hora e 24 horas de submersão. Foram analisadas vinte amostras, escolhidas aleatoriamente, de cada uma das cores de elásticos em cadeia sintéticos. Cada amostra, composta por 4 elos, foi inicialmente pré-estiradas, com o auxílio de duas sondas exploradoras, até o estresse. A determinação da quantidade de estiramento dos elásticos para aferição corresponde a 50% do valor do pré-estiramento inicial. Após a leitura inicial, cada um dos elásticos foi retirado do dinamômetro com o auxílio de uma pinça clínica e em seguida assentados sobre um gabarito com pinos desenvolvidos para acomodação dos elásticos. Os conjuntos (gabarito + elásticos) foram imersos em saliva artificial a 37 °C (histerese ± 1°). Nos intervalos de tempo 30 minutos, 1 hora e 24 horas. As amostras no tempo zero apresentavam diferenças significativas (p

Este trabalho discute alguns aspectos relacionados à dinâmica do agente físico atrito em aparelhos ortodônticos classificados como autoligáveis. Para isso, o mesmo apresenta dados relativos a um acompanhamento clínico realizado em um dos pacientes, sujeito de tratamento ortodôntico, durante o curso de especialização em ortodontia, realizada em uma instituição de ensino superior situada na região noroeste do estado do Paraná. Tal paciente apresentava principalmente mordida profunda, leve desvio da linha média e mordida cruzada anterior de incisivos laterais e central, em que foi utilizado um aparelho autoligável que dentre outras características, apresenta uma considerável redução no atrito durante a movimentação, dispensa ligaduras com uma consequente redução no tempo de tratamento. Após as análises, foi possível constatar o sistema autoligável apresenta vantagens significativas quando se considera a dinâmica do atrito.

Background: Frenula are fold-like structures of connective tissue that are inserted into the upper jawbone. This anatomical structure, which often goes unnoticed during the oral exam, presents insertion variations that are associated with diastemas, phonetic, periodontal, and orthodontic issues. Purpose: To identify the type of upper labial frenulum insertion associated with the presence of diastemas, in students aged 8 to 15 who attend the Vicente Anda Aguirre Educational Unit of the Mocha Canton, Ecuador. Methods: A descriptive study with a cross-sectional observational design, with a sample of 300 8-to-15-year-old children, who met the inclusion and exclusion criteria, was carried out. A clinical examination and photographic records of the upper labial frenulum were carried out/obtained to analyze the variables: type of insertion and presence of diastemas in relation to age and gender. Through Chi square test and linear regression, the association between these variables was evaluated (p = 0.05). Results: 44.67 % presented an upper lip frenulum with gingival insertion. Penetrating papillary insertion was found in 27.54% and was more closely related to the presence of diastema, with the mild type being the one that occurred most frequently (66.67 %) regardless of sex. Conclusions: Age showed a close relationship with the frenulum insertion site, being its most coronal location at an early age. Therefore, it could be a predisposing factor for the appearance of diastemas. [ABSTRACT FROM AUTHOR]

Amelogenesis imperfecta (AI) is an inherited disease that expresses a disorder in the development of enamel structure. In its mildest form, it promotes tooth color change; and in more severe cases, it presents a loss of enamel structure initiated during the eruption phase. Different AI manifestations can coexist in the same patient or in the same tooth, both in the primary and permanent dentures. In addition, several subtypes are described, characterized according to the variety of phenotype and genotype. Successful treatment requires early diagnosis and therapeutic solutions involving different dental specialties. Although some professionals prefer to postpone permanent rehabilitation until the development of complete permanent dentures, the aesthetic and functional impact of this disease in childhood and adolescence requires that restorative treatment be started as soon as possible. The proposed therapies demonstrate numerous challenges such as extreme dentinal sensitivity, difficulties installing and maintaining the orthodontic appliance and the need for restorative and prosthetic intervention in malformed teeth. This work aims to demonstrate the interaction between Orthodontics, Restorative Dentistry and Prosthesis in the treatment of a patient with AI, reporting the success of treatment involving aesthetics, function and well-being and the long-term benefit of this interdisciplinary approach for patients with this disease.

The literature is scarce on the intermaxillary elastics impacts on soft tissue during the treatment of Class II malocclusion The purpose of the present study was to compare the soft tissue changes after the treatment of Class II malocclusion using intermaxillary elastics with and without the premolars extraction. The sample consisted of 41 patients Class II Division 1 malocclusion with bilateral molar relationship of at least ½ cusp, divided into two groups. Group 1: 21 patients (mean age 18.97 years) treated for a mean period of 3.15 years with intermaxillary elastics without dental extractions. Group 2: 20 patients (mean age,17.40 years) treated for a mean period of 3.07 years with intermaxillary elastics and extraction of two maxillary premolars. Lateral cephalometric radiographs were used to measure the soft tissue and incisor variations before and after orthodontic treatment. Dolphin Imaging Premium software was used for radiographic analysis. Groups 1 and 2 were highly similar concerning age, initial overjet, molar relationship, treatment time, and initial cephalometric measurements. Statistically significant differences between both groups were observed (P<0.05) related to the anteroposterior position of the lower lip in Group 2 and facial convexity angle in Group 1. Conclusions: Both treatment modalities promoted similar effects on the facial profile, except for the greater retrusion of the lower lip in the protocol with extractions and decrease in the facial convexity in the protocol without extractions.
