The aim of this study was to evaluate the effectiveness of root canal preparation with Nitiflex file and Flexofile. Forty mesio-buccal upper molar roots were used. After the preparation, the root canals were molded using an impression paste being then examined for the presence or absence of apical deviation, taper and surface. The results did not indicate any statistical difference between the use of the two types of instruments.

We evaluated tensile bond strengths between a nickel-chromium alloy and cements at different times (one and 90 days) using or not thermocycling. Alloy used was Litecast B, and luting cements were Ketac-Cem, Vitremer, and Fluoride Enforce with three variations: a) only primer; b) with primer and bond; c) only with bond. Metallic discs with 6 mm diameter were cemented together and immersed in distilled water. Half specimens were thermocycled and half one not. Conclusions were: Ketac-Cem presented low bonding strength, being that of Vitremer very higher; the material Enforce when used only with primer increased adhesion with time but yet remained relatively low after 90 days; Enforce used with bond only achieved superior adhesion, still present specially with termocycling after 90 days; influence of thermocycling depends on adhesive system.
我们评估了镍铬合金与水泥在不同时间(1天和90天)使用或不使用热循环的拉伸结合强度。使用的合金为Litecast B，粘结剂为Ketac-Cem、Vitremer和氟化物强化剂，有三种变化:a)仅底漆;B)带底漆和粘结剂;C) only with bond。将直径为6毫米的金属盘粘合在一起，浸入蒸馏水中。一半的标本进行了热循环，一半没有。结论:Ketac-Cem的结合强度较低，而Vitremer的结合强度较高;仅与底漆一起使用时，材料的附着力随着时间的推移而增加，但在90天后仍然相对较低;仅与粘结剂配合使用，达到优异的附着力，90天后仍具有特殊的摩托车性能;热循环的影响取决于胶粘剂体系。

A mouthrinse containing cetylamine fluoride (230 ppm in fluoride) was prepared for in vitro studies of fluoride clearance and adsorption by enamel and/or hydroxyapatite using a device that simulates the oral cavity. In vivo studies of fluoride clearance from this mouthrinse were conducted and compared with other fluoride sources. The amount of fluoride adsorbed to tooth blocks or powdered hydroxyapatite, both treated with this cetylamine fluoride mouthrinse once or twice a day, was determined. The results of these studies showed that it is possible to prepare a mouthrinse with cetylamine fluoride for alternative use by patients for the prevention and therapy of dental caries.

A microinfiltracao marginal de restauracoes de amalgama classe II (Dispersalloy), associada ao verniz convencional (Copalite) e a dois adesivos dentinarios (Scotchbond Multi-uso Plus e Multi Bond Alpha), foi avaliada e comparada in vitro atraves de dois metodos: escores e medidas lineares. Foram utilizados 45 pre-molares higidos que receberam duas cavidades independentes M e D. Apos a restauracao, foram submetidos a termociclagem e armazenados em uma solucao de fucsina basica a 0,5% durante 24 horas. A analise da infiltracao do corante permitiu concluir que nenhum dos tres sistemas restauradores foi capaz de eliminar a microinfiltracao marginal. No entanto, ela foi menor e estatisticamente significante para as restauracoes associadas aos adesivos dentinarios, quando comparadas aquelas com o verniz cavitario. O metodo das medidas lineares foi mais sensivel do que o de escores.
在体外，采用评分和线性测量两种方法对II类汞合金(分散合金)与传统清漆(Copalite)和两种牙本质粘接剂(Scotchbond Multi-uso Plus和Multi Bond Alpha)修复的边缘微渗漏进行了评估和比较。45颗前磨牙分别接受两个独立的牙腔M和d，修复后进行热循环，在0.5%的碱性品红溶液中保存24小时。对染料渗漏的分析表明，三种修复系统都不能消除边缘微渗漏。然而，与牙本质黏合剂相关的修复相比，它更小，具有统计学意义。线性测量法比评分法更敏感。

O crescente numero de infeccoes fungicas bucais em pacientes imunocomprometidos tem estimulado a pesquisa de drogas mais eficientes. Procuramos, assim, avaliar a suscetibilidade in vitro de cepas de Candida albicans de pacientes com câncer submetidos ou nao a radioterapia frente as seguintes drogas: anfotericina B, cetoconazol, miconazol e itraconazol. A tecnica de diluicao em agar YNB e o subcultivo em AS foram respectivamente utilizados para determinacao da CIM (Concentracao Inibitoria Minima) e da CFM (Concentracao Fungicida Minima). Com esta metodologia, a droga que mostrou melhor atividade antifungica para cepas de C. albicans isoladas de qualquer dos grupos de pacientes foi a anfotericina B, apresentando baixos valores de CIM em comparacao aos azois, e de CFM. Contudo, e necessario lembrar que o tratamento com antibioticos polienicos pode causar efeitos toxicos, mesmo em doses necessarias para se atingir bons resultados com os antifungicos. A coexistencia de outras especies nesses pacientes, principalmente entre os submetidos a radioterapia, as condicoes locais, bem como o uso de outras drogas, devem ser tambem considerados. Acredita-se, porem, que o uso adequado dos antifungicos atuais e a disponibilidade de novas drogas que nao produzam consequencias indesejaveis possam conduzir a melhores resultados na clinica diaria.

In the search for the recovery of the dental aspect, the porcelain stands out among restoring materials. The use of this material has increased considerably over the last years, therefore increasing the probability of fractures. Even so, not every failure demands the restoration of the material: the possibility of a repair exists with compounded resin. This study proposed to evaluate in vitro the bonding strength of the composite resin to feldspathic porcelain with several surface treatments: roughened with diamond burs or sandblasted with aluminum oxide of 50 micra, isolated or associatedly etched with phosphoric acid for 15 seconds, or with hydrofluoric acid for 1 or 4 minutes. All the specimens were previously regularized with 220-grit silicon carbide paper. After the superficial treatments, they received the adhesive system for porcelain, Scotchbond Multi-Purpose Dental Plus Adhesive System (3M). After making the union with the composed resin (Restorative Z100, 3M), they were stored in distilled water at 37oC, for 7 days, followed by thermocycling (600 cycles of 1 minute, between 5 and 55oC), and submitted to a tensile strength test. With the obtained results, the conclusion was that with all the proposed treatments an improvement happened in the resistance of the tensile bonding strength (when compared to those observed in the group control without any superficial treatment). The sandblasting produced a better resistance than the roughening with a diamond bur; but, when associated to the etching with any of the selected acids, independent of the time of application, there was no statistical difference among those treatments.
在修复牙齿方面的研究中，瓷器在修复材料中脱颖而出。在过去几年中，这种材料的使用大大增加，因此增加了骨折的可能性。即便如此，并不是所有的故障都需要修复材料:复合树脂存在修复的可能性。本研究提出在体外评估复合树脂与长石瓷的结合强度，采用几种表面处理:用金刚石毛刺粗化或用50微米的氧化铝喷砂，用磷酸分离或联合蚀刻15秒，或用氢氟酸蚀刻1或4分钟。所有的样品之前都用220粒度的碳化硅纸进行了规整。表面治疗后，他们接受了瓷粘接系统，Scotchbond Multi-Purpose Dental Plus adhesive system (3M)。与复合树脂(Restorative Z100, 3M)结合后，在37℃的蒸馏水中保存7天，然后在5 ~ 55℃之间进行热循环(600次，1分钟)，并进行拉伸强度测试。根据所获得的结果，结论是，在所有提出的治疗中，抗拉结合强度都有所改善(与未进行任何肤浅治疗的对照组相比)。喷砂比金刚钻粗化的耐磨性好;但是，当与任何选定的酸蚀刻相关联时，与应用时间无关，这些处理之间没有统计学差异。

Tendo em vista a indefinida literatura em relacao aos macrofagos e a fagocitose de fungos, bem como os resultados conflitantes frente a diversas metodologias empregadas, propusemo-nos a estabelecer um modelo experimental para estudar a fagocitose de Candida albicans. Utilizamos macrofagos peritoneais ativados, obtidos de camundongos isogenicos da linhagem A/SN e duas cepas de Candida albicans, sendo uma sorotipo A e a outra B, apresentando diferentes niveis de patogenicidade in vivo. Avaliamos a fagocitose pela contagem de macrofagos contendo em seu interior celulas vivas e/ou mortas, determinando-se o indice de fagocitose pela multiplicacao da porcentagem de macrofagos que fagocitaram e do numero medio de leveduras por macrofagos. Valemo-nos de corantes vitais como vermelho neutro e fluorescentes (diacetato de fluoresceina e brometo de etidio), examinando o material a luz da microscopia de fase e fluorescencia. Pudemos concluir que este e um modelo eficiente, em face da metodologia utilizada, onde verificamos um comportamento diferente dos macrofagos em relacao as duas cepas estudadas; a porcentagem e o indice de fagocitose dos macrofagos foram maiores frente a cepa de Candida albicans sorotipo A (nao patogenica in vivo), quando comparada a de sorotipo B, embora o numero medio de leveduras por macrofagos fosse semelhante para ambas as cepas.

This study was performed to compare the severity of Craniomandibular Disorder's (CMD), signs and symptoms in 29 subjects with shortened dental arches (SDA), who required prosthodontic treatment and were followed and longitudinally evaluated for two years after the removable partial denture (RPDs) treatment. In each case, to measure and compare differences before and after reconstruction procedures, the degree of severity of CMD was checked on a score basis methodology, following clinical history, muscular and temporomandibular joint (TMJ) sensibility examination, clicking and mandibular movements (MM) registration. Twenty-nine other subjects acted as a control group. After non parametric statistical analysis it was concluded that subjects had a significant higher CMD severity prevalence before RPD treatment and that an adequate indication and treatment with RPD acts positively, resulting in a decline in the prevalence of these disorders.

Periapical and panoramic radiography with a ellipsopantomograph device, are compared in the evaluation of endodontic treatment. With this objective, radiographies carried out under both techniques with the same patient having at least one tooth endodontically treated, were analysed by three observers, taking into consideration the apical conditions (periapical lesions), the root canal filling (material type, filling and apical level), tooth restoration and filling of the pulpar camera. The results demonstrated that periapical radiography is a better way to define the appearance of difuse periapical bone rarefaction, root canal filling with gutta-percha, insatisfactory endodontic treatment, an inadequate juxtaposition of the restoration material to the anterior region, and the presence of metallic casted restorations in the posterior region. Other result evaluations were not significant. The diagnostic agreement among the observers is higher in periapical radiography.

The diagnostic agreement among the observers is higher in periapical radiography.","PeriodicalId":77611,"journal":{"name":"Revista de odontologia da Universidade de Sao Paulo","volume":"13 1","pages":"295-302"},"PeriodicalIF":0.0,"publicationDate":"1999-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67654129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dental caries is a chronic infectious disease that needs at least four components to develop. As a susceptible host, a pathogenic microbiota, a high-sucrose diet and time. This work assess the relationships between Streptococcus mutans and dental plaque; Streptococcus mutans and IgA antibodies in children with and without caries experience. In order to achieve this goal we have used Mitis Salivarius bacitracin agar (DIFCO) to determine the colony forming units (CFU/mL), the simplified oral hygiene index (SOHI) for measuring bacterial plaque and ELISA for antibody detection. The results obtained have not shown any correlations between colony forming units of S. mutans and IgA antibodies. A significant correlation was found between bacterial plaque index and specific IgA in children with carious lesions.
龋齿是一种慢性传染病，至少需要四个因素才能形成。作为一个易感宿主，一个致病菌群，一个高蔗糖的饮食和时间。本研究评估了变形链球菌与牙菌斑之间的关系;有无龋齿患儿的变形链球菌和IgA抗体。为了达到这一目的，我们采用Mitis Salivarius bacitracin agar (DIFCO)测定菌落形成单位(CFU/mL)，简化口腔卫生指数(SOHI)测定菌斑，ELISA检测抗体。获得的结果没有显示变形链球菌的集落形成单位和IgA抗体之间的任何相关性。龋齿患儿菌斑指数与特异性IgA有显著相关性。
