Teeth that have lost much of their coronal tooth structure need intraradical devices to achieve a desired retention of the restorative material, restoring aesthetics and function to the patient. For this purpose, various types of intracanal posts have been studied, of wich the fiber posts have been highlighted with its increasing use in the dental market. The purpose of this study was to present a clinical case of using fiberglass post. As well as critically analyze the published works and points of controversy described by different authors related to factors such as different protocols cementation, surface treatments pins, fracture toughness and compression, the possibility of microleakage, diameter and length of the pin, and the various materials used in conjunction with the intracanal retainers. Thus, we concluded that fiber posts showed as an excellent alternative for anterior teeth, since have least 2 mm of tooth remaining.

Objective: Tooth decay is one of the more common diseases of childhood. Several studies recommend that early preventive measures must be implemented since the first years of life and continue throughout childhood and adolescence. The aim of the this study was to present results of a preventive dental program considering oral health maintenance, dental caries experience and the prevalence of dental caries relation with follow-up compliance visits. Material end method: Intraoral and interproximal radiographic exams were performed on 171 patients participants of a preventive dental program. Data regarding age, gender, previous caries experience and the frequency at which the patients attended return visits were obtained from the records. The data were analyzed statistically by the McNemar test, with the level of significance set at 1%. Result: Clinical and radiographic examination revealed that most children participating in the program had sound teeth (77.2 and 84.8%, respectively). The past dental history of the dental caries from patients included in this study showed statistical relevance when associated with the present dental caries experience and a statistical relationship was found from the absence of compliance to clinical visits and the dental caries presence. Conclusion: The preventive strategy had a positive influence on oral health maintenance in the children examined. Previous caries experience and the lack of compliance with return visits influenced the clinical oral condition of the children during participation in the preventive program.

Dental plaque is the principal etiological agent of periodontal disease, one of oral diseases more prevalent in the world. Due existence of relation between periodontal disease and oral hygiene, on the point of periodontal view, it was developed a growing interesting by experimental research and by clinical investigations. The knowledge of problem, its extension, severity, hypothetic cause is so valuable to establish prevention, control and treatment acts. In this form, the use of plaque index becomes more and more often, being valuable the determination of discriminatory power of them. The aim of this work was to describe and analyze principal forms to register of dental plaque aiming to subsidize the researcher and dental surgeon on adoption of most adequate method for their case. Data bases: Medline, Lilacs and BBO were consulted without limit to identify the format of register of each index described on literature. It was observed the use of Oral Hygiene Index on diverse ways like: clinical evaluation of dental plaque, in products evaluation works and dental Office; patients monitoring; instruction about hygiene and oral hygiene technique. It was noted that dental plaque indexes are useful and allows the register of different forms point out the importance of its use on clinical and researches practice.

The increase of the retentive areas of bacterial plaque can be observed in patients who use dental braces in the mouth. The difficulty of making hygienic is one of the problems that this particular group of patients faces day by day, and consequently, the establishment of gingival inflammation becomes more frequent. The objective of this case report is to show the importance of the periodontist in preventing and promoting health to the users of dental braces, aimed at education and motivation as one of the priorities of this treatment. The ESA patient, 29 years old, male, attended the dental office of a periodontist, sent by the orthodontist, due to the extensive area of gingival hyperplasia and gingivitis, in both arches. The possibility of taking out the dental braces was considered by the orthodontist, but after the periodontist evaluation, this step was procrastinated. Thus, the periodontist started the adequacy of the oral environment together with the work of education and promotion of health, which lasted until the complete recovery of the healthy gingival condition of the patient. In this way, it is possible to observe the relevance of the work of the periodontist in the application of preventive methods in oral health for orthodontic patients. The motivation of these patients in relation to the orientations of buccal hygienic, maintenance of oral health and diet should not be considered as secondary and should be prioritized, because only in this way it would be possible to reach a good occlusion, without esthetic and functional prejudice.

During clinical routine, the orthodontist uses several materials, which include metallic alloys in the form of metallic wires. However, it is necessary that the professional has some knowledge of the properties of those wires. Different types of wires are commercially available: stainless steel wires, chrome-cobalt wires, nickel-titanium wires and beta-titanium wires. Among the nickel-titanium wires, there are three subdivisions: a conventional alloy and two superelastic alloys. The superelasticity, associated to the effect of form memory, is a property used in orthodontics to initiate the dental movement in the first phase of the orthodontic treatment. This property is considered to be biologically compatible with the effective dental movement. These wires are available at the market in different transformation temperatures, and they offer the best adaptation in the groove of the bracket, simplicity and a faster treatment. However, they present little formability, and they don’t accept solder. They are also more onerous than other wires. Moreover, the low rigidity of these wires doesn’t allow them to be used for the retraction of the anterior teeth or closing of spaces. Therefore, the coherent use of superelastic orthodontic wires is recommended, accompanied by a detailed diagnosis and planning, so the result will be an efficient orthodontic correction, accomplished in a shorter period of time.

A Ortodontia apresenta como um de seus pilares de sustentação as reações biológicas provenientes da indução mecânica. Desde seu início, vários estudos foram realizados para esclarecer os eventos biológicos decorrentes da movimentação dentária sob indução mecânica. Entretanto, mesmo sabendo-se que entre os procedimentos mecânicos e os fenômenos biológicos que acontecem no cotidiano ortodôntico não deve ocorrer disparidade, frequentemente observa-se uma preponderância para a busca do tipo de aparelhagem e o emprego de forças controladas, principalmente pelos fios. Esses aspectos deixam transparecer, principalmente para o profissional menos experiente, que somente o controle mecânico rege a movimentação dentária. Um exemplo que enfatiza exclusivamente o procedimento mecânico nos cursos de Ortodontia é o typodont. Convém salientar que essa metodologia de ensino é válida para simular a movimentação dentária no aspecto técnico-mecânico, porém, o conhecimento biológico da movimentação deve ter o mesmo nível de importância e não pode haver dicotomia; caso contrário, o resultado da movimentação ortodôntica pode causar prejuízos nas estruturas radiculares, óssea e periodontais, bem como comprometer as diversas estruturas em longo prazo.

Objective: To conduct a survey on national databases about Oral Health Program (OHP) publications in schools, in the last eleven years. Material and Methods: A survey was conducted in two main bases of national publications in the field of dentistry: Bireme and Scielo. To start the research, it was used the articles theme/subject. In the search, it was used the keywords 'oral health education', 'programs and oral health and dentistry', 'programs and oral health and education'. Results: A total of 20 publications were selected. From these, seven (35%) had the aim to evaluate educational methods used in OHP, 12 (60%) evaluated the effectiveness of the OHP itself developed in the school and one (5%) reported the experience of OHP. Only two publications did not get positive results and the other eighteen obtained advantageous results. Conclusion: In the national scientific literature, there are few publications about the subject in question, suggesting that the successful experiences about OHP in schools must be published to be replicated in other parts of Brazil.

Esse trabalho teve como objetivo avaliar, clinicamente, a efetividade de dois agentes clareadores aplicados sobre a superfície dentária durante 45 minutos, sem troca do gel. Foram selecionados 10 pacientes de acordo com os critérios de inclusão e exclusão, e a arcada superior dos pacientes foi dividida em duas hemiarcadas (n = 10): na hemiarcada direita (HD), foi aplicado o peróxido de hidrogênio a 35% (PH) Clàriant Office (Angelus); e, na hemiarcada esquerda (HE), o PH 38% Opalescence Boost (Ultradent). Foram realizadas duas sessões clínicas, de 45 minutos cada, com intervalo de uma semana entre as sessões. Inicialmente, ao tratamento clareador, os pacientes receberam profilaxia, moldagem para guia de mensuração de cor com silicone de condensação e avaliação de cor por meio de um aparelho espectrofotômetro Vita Easyshade (Vita Zhanfabrik, Alemanha). Após 14 dias do término do tratamento clareador, foi realizada a mensuração final da cor dos dentes. Os dados foram submetidos ao teste t e de Tukey (p < 0,05). Os resultados demonstraram não haver diferença estatisticamente significativa entre as hemiarcadas quanto à efetividade do clareamento (p = 0,146) e nem quanto à sensibilidade. Pode-se concluir que a aplicação dos materiais avaliados sem troca do gel, por 45 minutos, foi eficaz em promover o clareamento de dentes vitais e com baixa sensibilidade dentária.

Objetivo: o objetivo desse estudo in vivo foi avaliar a influência da infiltração coronária no reparo apical de dentes de cães que receberam curativo de demora com hidróxido de cálcio e foram mantidos, ou não, em contato com o meio bucal. Métodos: após o preparo biomecânico e preenchimento com pasta de hidróxido de cálcio, 26 canais foram divididos aleatoriamente em dois grupos experimentais (Grupo 1 = selamento coronário com material restaurador temporário; Grupo 2 = não selados). Os animais foram sacrificados após 7 dias e os espécimes foram preparados para análise histológica. Resultados: em ambos os grupos, os resultados foram semelhantes, células inflamatórias não estavam presentes no tecido apical ou no cemento. Além disso, observou-se necrose na superfície do terço coronário do coto pulpar em contato com o hidróxido de cálcio, e microrganismos foram observados apenas em contato com resíduos que estavam presentes na câmara pulpar dos espécimes sem selamento, mas não no canal radicular. Conclusão: concluiu-se que o hidróxido de cálcio utilizado como curativo impediu a contaminação do canal radicular e manteve seu mecanismo de ação nos tecidos apicais, mesmo sem selamento coronário, por um período de 7 dias.
