| The composition of saliva is essential for the oral cavity homeostasis, therefore, the decrease in salivary flow leads to consequences, such as an increase of dental caries, dry mouth and lips, dysgeusia, dysphagia, gingivitis, halitosis, mastication problems, oral mucositis, oral pharyngeal candidiasis, sleeping and speaking difficulties and traumatic oral lesions. The objective of this study was to evaluate the efficacy of the sialometry technique by weighing in comparison to the sialometry technique by volume. Fifty patients without previous complaint of xerostomia and/or hyposalivation were selected at the Oral Medicine Clinic, Dentistry School, University of São Paulo, Brazil. All samples were collected between 9 am and 10 am and the whole saliva was collect stimulated and unstimulated. Six cotton rolls were prepared, divided into three pairs and placed in different universal dispensers of a random brand, they were weighed in a previously calibrated analytical balance (FA-2104N CELTAC). The sialometry test was performed in three steps: unstimulated salivary flow, salivary flow with stimulation of 1% citric acid solution and stimulation of 1% citric acid solution every 30 seconds. The results of the weighing method were compared to the standard method. There was no significant statistical difference between the two types of collection and 100% of the participants expressed their preference for the weighing method.

RESUMO | Comparação de dois métodos de sialometria: técnicas de pesagem e volume • A composição da saliva é essencial para homeostase da cavidade oral. Assim sendo, a diminuição do fluxo salivar pode levar ao aumento da incidência de cáries, boca seca, alteração no paladar, alteração na deglutição, gengivite, halitose, problemas mastigatórios, mucosites, candidíases, problemas no sono, fala e lesões orais traumáticas. O objetivo deste estudo foi avaliar a técnica de sialometria por peso em comparação com a técnica tradicional de sialometria por volume, com coleta de saliva estimulada e não estimulada. Cinquenta pacientes com ou sem queixa prévia de xerostomia ou hipossalivação foram selecionados na clínica de Estomatologia da Faculdade de Odontologia da Universidade de São Paulo, Brasil. Todas as coletas foram realizadas entre 9 e 10 horas da manhã. Seis rolos de algodão foram separados e divididos em três pares e colocados em três diferentes coletores plásticos universais, sendo cada conjunto pesado previamente em balança analítica calibrada. O teste de sialometria foi realizado em três etapas: fluxo salivar sem estimulação; estimulado com 1% de ácido cítrico em aplicação única; e estimulado com aplicação de 1% de ácido cítrico a cada 30 segundos até completar 2 minutos. Esses resultados por peso foram comparados com o método de sialometria por volume tradicional. Não houve diferença estatística observada entre os dois métodos de coleta e 100% dos pacientes
唾液的成分对口腔内稳态至关重要，因此，唾液流量的减少会导致后果，如龋齿增加，口唇干燥，发音困难，吞咽困难，牙龈炎，口臭，咀嚼问题，口腔黏膜炎，口腔咽念珠菌病，睡眠和说话困难以及创伤性口腔病变。本研究的目的是通过称重来评估唾液测定技术与体积测定技术的效果。在巴西圣保罗大学牙科学院口腔医学诊所选择了50例既往无口干和/或唾液分泌不足的患者。所有样本在上午9点至10点之间采集，收集了受刺激和未受刺激的全部唾液。准备6个棉卷，分成3对，放置在随机品牌的不同通用分配器中，在先前校准的分析天平(FA-2104N CELTAC)中称重。唾液测定试验分为三个步骤:未刺激的唾液流、1%柠檬酸溶液刺激的唾液流和1%柠檬酸溶液每30秒刺激一次的唾液流。将称重法的结果与标准方法进行了比较。两种收集方法之间没有显著的统计学差异，100%的参与者表示他们更喜欢称重方法。描述物|唾液;唾液消除;唾液腺;唾液分泌。<s:1> <s:1> <s:1> <s:1> <s:1> <s:1> <s:1> <s:1> <s:1> <s:1>唾液测量仪:<s:1> <s:1> <s:1>唾液测量仪:<s:1> <s:1>唾液测量仪:<s:1> <s:1>唾液测量仪:<s:1>唾液测量仪。Assim sendo, a miniui。目的:比较<s:1> <s:1> <s:1> <s:1> <s:1> <s:1> <s:1> (<s:1>)与<s:1> <s:1> <s:1> (<s:1>)、(<s:1>)和(<s:1>)两种传统唾液量的差异。Cinquenta pacientes com ou sem queixa前置de口腔干燥或者hipossalivacao有孔虫selecionados na我们de Estomatologia哒Faculdade de Odontologia哒圣保罗,巴西。今天，我们将为您提供一个可实现的数据中心，例如:manhã。Seis rolos de algoda o foram separados e divididos em três pares e colocados em três不同的coletores plásticos universais, sendo cada conjunto pesado preamente em balan<s:1> analítica calibrada。0 .唾液量测定法的研究进展três实验方法:液体唾液刺激法;Estimulado com 1% de ácido cítrico em application a<s:1> <e:1> o única;E estimulado com applicationalo de 1% de ácido cítrico a cada 30秒，完成2分钟。研究结果表明，与传统的唾液量测定方法相比，该方法的效果较差。9 .有不同的<s:1> <s:1> <s:1> <s:1> <s:1> <s:1>观察中心，所有的患者都有不同的<s:1> <s:1> <s:1> <s:1>和其他的<s:1> <s:1> <s:1>和其他的。描述物|唾液;Eliminacao Salivar;腺Salivares;Salivacao。通讯作者|•Celso Augusto Lemos-Júnior圣保罗大学牙科学院口腔科•Av.教授Lineu presstes, 2227 s<s:1> o Paulo, SP, Brazil•05508-000 E-mail: calemosj@usp.br•2016年11月17日收到•2017年7月12日接受•DOI http://dx.doi.org/10.11606/issn.2357-8041.clrd.2017.122887两种体积测量方法的比较:称重和体积技术2●临床实验室研究报告2017:唾液腺是人类内分泌系统中大量腺体的一部分，它们通过分泌唾液来维持口颌系统的平衡唾液对口腔黏膜的稳态至关重要，唾液中的一些物质有助于维持口腔组织的完整性。粘蛋白是颌下腺、舌下腺和小腺体的主要产物，它负责为粘膜提供润滑和保护组他素负责维持高水平的可用钙，从而改善牙齿再矿化和具有抗菌特性的组他素。3-5因此，唾液流量减少会造成后果，如龋齿增加、口唇干燥、发音困难、吞咽困难、牙龈炎、口臭、咀嚼问题、粘膜炎、口咽念珠菌病、睡眠和说话困难以及创伤性口腔病变。6,7随着预期寿命的增加，由于药物使用的增加和全身性疾病，越来越多的老年人抱怨口干，口干症。有研究试图证明唾液流量随着年龄的增长而减少，这种减少对老年人的生活质量有显著的影响。

Oral rehabilitation with free-end removable partial denture (RPD) is one of the major challenges in prosthodontic dentistry. The absence of a distal abutment produces undesirable RPD movement during masticatory function due to the high resilience of the residual ridge, which limits the denture efficiency and may damage the abutment teeth and bone over time. The advent of dental implants made possible to substitute the missing teeth with fixed implant-supported dentures as the first choice treatment to overcome such inconveniences. However, this indication may not be suitable for all patients due to financial, anatomical or systemic health conditions. Nevertheless it is possible to improve free extension RPD by using implants in the posterior edentulous ridge to achieve biological, biomechanical, physiological and social benefits. This article aims to present a case report on oral rehabilitation in which a RPD was made combined with an implant for posterior support in a sizeable edentulous ridge. The patient appreciated the retention improvement and the aesthetic result. The combination of a RPD with a posterior implant is an alternative treatment for cases in which implant-supported fixed prosthesis is not indicated, reducing the displacement and minimizing the limitations of the free-end devices.

Objective : to measure pH values of bleaching agents that are indicated to intracoronal bleaching technique in different time intervals. Methods : Each group (G) received five samples (n=5): G1 – distilled water (AD); G2 – hydrogen peroxide (H2O2) 30%; G3 – sodium perborate (PbS) + AD; G4 – PbS + H2O2 30%; G5 – sodium percarbonate (PcS) + AD; and G6 – PcS + H2O2 30%. pH values were stated using a digital pHmeter, in different time intervals: immediately after handling (T0), 24 hours (T1) and 168 hours after handling (T2). The results were submitted to statistical analysis through Kruskal-Wallis and Mann Whitney tests, in this order, allowing multiple comparisons among the groups. To verify the effect of time in each group, Friedman test was applied. Results : In the evaluation of the effect of time in each group, it was observed that G2 presented acid behavior, while the other groups exhibited values close to neutrality or alkaline. Conclusions : H2O2 30% was the only agent that showed acidic behavior in every evaluation time. Meanwhile, PcS + H2O had the highest pH values.

| Objectives: To analyze the accuracy of a pre-fabricated self-perforating tray for implant impression in an edentulous maxilla. Methods: Four implants (13, 16, 23, 26) were placed in an acrylic resin model of an edentulous maxilla. Implant impressions (n = 7) were taken using a customized open tray (Control Group) and a pre-fabricated selfperforating tray (Test Group). A metal bar was fabricated and screw-retained on implant 13 and the vestibular gap between the framework and implants was measured by stereomicroscopy on implants 16, 23, and 26. Data were analyzed by ANOVA repeated measures and Tukey tests with a significance level (α) of 0.05. Results: There was no statistical difference between self-perforating and customized open tray groups. Control group showed a gap of 73.31± 26.01 for I1; 149.16± 53.90 for I2; and 115.46± 73.34 for I3. Whereas Test Group showed a gap of 154.41± 74.64 for I1; 159.45± 87.64 for I2; and 109.28± 49.18 for I3. Conclusion: The pre-fabricated self-perforating and custom trays showed a similar accuracy for implant impression of edentulous maxilla.

Implant impressions (n = 7) were taken using a customized open tray (Control Group) and a pre-fabricated selfperforating tray (Test Group). A metal bar was fabricated and screw-retained on implant 13 and the vestibular gap between the framework and implants was measured by stereomicroscopy on implants 16, 23, and 26. Data were analyzed by ANOVA repeated measures and Tukey tests with a significance level (α) of 0.05. Results: There was no statistical difference between self-perforating and customized open tray groups. Control group showed a gap of 73.31± 26.01 for I1; 149.16± 53.90 for I2; and 115.46± 73.34 for I3. Whereas Test Group showed a gap of 154.41± 74.64 for I1; 159.45± 87.64 for I2; and 109.28± 49.18 for I3. Conclusion: The pre-fabricated self-perforating and custom trays showed a similar accuracy for implant impression of edentulous maxilla.

RESUMO | Precisão de moldeira autoperfurante para impressão de implante dentário maxilar • Objetivos: Analisar a precisão de uma moldeira autoperfurante de impressão pré-fabricada para implantes na maxila edêntula. Métodos: Quatro implantes (13, 16, 23, 26) foram colocados em um modelo de resina acrílica de uma maxila edêntula. As impressões dos implantes (n = 7) foram tiradas com uma moldeira aberta customizada (Grupo Controle) e uma moldeira autoperfurante pré-fabricada (Grupo Teste). Uma barra de metal foi fabricada e aparafusada no implante 13, e o gap vestibular entre a estrutura e os implantes foi medido por estereomicroscopia nos implantes 16, 23 e 26. Os dados foram analisados por Anova de medidas repetidas e teste de Tukey, com um nível de significância (α) de 0,05. Resultados: Não houve diferença estatística entre os grupos de moldeiras, tanto autoperfurante quanto aberta customizada. O grupo controle apresentou gaps de 73,31 ± 26,01 para I1; 149,16 ± 53,90 no I2; e 115,46 ± 73,34 para o I3. Ao passo que o Grupo Teste apresentou gaps de 154,41 ± 74,64 no I1; 159,45 ± 87,64 no I2; e 109,28 ± 49,18 para o I3. Conclusão: A moldeira autoperfurante pré-fabricada e a moldeira customizada apresentaram precisão similar na impressão de implantes da maxila edêntula.

Objective: The tensile strength effects on the sandblasting of the abutment associated with a cementing technique are not well documented. The objective of this study is to analyze the tensile strength of prosthetic crowns cemented on standard and sandblasted abutments, using a cementing technique. Methods: Experimental groups were formed according to cementing technique (control and practice abutment technique) and prosthetic abutment roughness (standard and sandblasted), totaling forty specimens. The crowns were cemented with Zinc Phosphate cement. Statistical analysis was conducted with an α at 0.05. Results: Considering the cementation techniques analysis, there were no statistically significant differences between the groups, with mean tensile strength values of 157.83±22.16 N for the control technique, and 159.95±46.40 N for the practice abutment technique on the standard surface. Result analysis of the control technique (626.23±34.80 N) and practice abutment technique (642.62±94.00 N) indicated no significant differences on the sandblasted surface. Considering the surface roughness analysis, significant differences were observed, with values of 157.83±22.16 N for the control technique/standard surface group and 626.23±34.80 N for the control technique/sandblasted surface group. Significant differences were observed in the practice abutment technique/standard surface group with 159.95±46.40 N values, compared to the 642.62±94.00 N value for the practice abutment technique/sandblasted group. Conclusions: The practice abutment cementing technique showed no significant differences with the control technique, regarding to the tensile strength, in the two surfaces (standard and sandblasted) used in the study. The sandblasting of prosthetic abutments led to a significant increase on the tensile strength considering the two studied cementation techniques.

| Chronic periapical lesion is among the most usual bone pathology observed in human teeth, and it is often first detected by plain radiographs, such as panoramic or periapical radiography. Plain radiographs are widely used in dentistry; ho-wever, they have limitations inherent to the technique itself, such as anatomic structures overlapping and lack of information on the extension of the lesion. Therefore, three-dimensional radiographic methods, such as cone beam computed tomography are valuable to accurately assess periapical lesions. Thus, this clinical report describes a case in which the bone radiographic features led to a primary diagnosis of chronic periapical lesion in superior incisors, however, it was a defect in the palatal bone. The resulting radiolucency created by the palatal bone defect overlapped the maxillary bone, mimicking a periapical lesion. Additionally, in the same case, we demonstrate a true chronic periapical lesion in another area that presented as a subtle radiolucency in periapical radiography, however, it was larger than expected when evaluated in Cone Beam Computed Tomography.

Objetivo : Hipomineralizacao incisivo-molar (HIM) e um disturbio de desenvolvimento dentario altamente prevalente devido a maturacao interrompida do ameloblasto. Esta condicao afeta ate 44% das criancas ao redor do mundo e varias condicoes sistemicas tem sido associadas a HIM, incluindo a respiracao oral. E importante mostrar que HIM tem etiologia multifatorial e esta associada com criancas alergicas com respiracao bucal. Metodos : Para avaliar a prevalencia da HIM em criancas com SRBI com resposta alergica positiva e negativa para testes de escarificacao, uma avaliacao transversal quantitativa e qualitativa foi realizada em 23 criancas com respiracao oral e 25 irmaos com idade/sexo correspondentes. Defeitos de esmalte foram classificados de acordo com o indice de defeitos de esmalte da FDI. Teste t de Student foi aplicado para verificar a relevância dos dados. Resultados : A prevalencia de HIM mostrou diferencas estatisticas significativas na comparacao entre molares, independentemente de idade individual (p = 0,01513474). Criancas com SRBI menores de 5 anos apresentaram maior prevalencia estatistica de HIM (p = 0,00594). Criancas com SRBI que obtiveram reacoes positivas para os testes de escarificacao apresentaram maior prevalencia de HIM (p = 0,023). Criancas com SRBI apresentaram maior prevalencia estatistica de opacidade demarcada (p = 0,00012). Conclusoes : Criancas com SRBI que obtiveram reacoes positivas para os testes de escarificacao apresentaram maior prevalencia de HIM (p = 0,023), indicando que criancas alergicas com respiracao oral tiveram maior prevalencia de HIM. Nossos resultados corroboram nossa hipotese anterior que criancas com SRBI demonstram maior prevalencia de HIM em comparacao com seus irmaos, com significância estatistica (p = 0,01513474). Investigacoes com amostras populacionais maiores podem reforcar e confirmar a exatidao dos nossos resultados.
