2. Accuracy of Irradiance and Power of Light-Curing Units Measured With Handheld or Laboratory Grade Radiometers
Resumo Esse estudo mensurou e comparou a irradiância e a energia de quatro fotopolimerizadores comerciais (Elipar S10, Elipar DeepCure-S, Corded VALO e Bluephase Style) utilizando diferentes tipos de radiômetros. Os dispositivos utilizados para analisar os fotopolimerizadores foram classificados em portáteis analógicos (Henry Schein, Spring, Demetron 100

3. Influence of dental occlusion on the athletic performance of young elite rowers: a pilot study
OBJECTIVES: The present study aimed to assess the influence of dental occlusion on body posture and the competitive performance of young elite rowers. METHOD: Dental occlusion disturbance devices were used to simulate dental malocclusions. We assessed the influence of malocclusion on the body balance, paravertebral muscle contraction symmetry, and muscular

4. In situ effect of CPP-ACP chewing gum upon erosive enamel loss
Abstract Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) is able to increase salivary calcium and phosphate levels at an acidic pH. Previous studies demonstrated that a CPP-ACP chewing gum was able to enhance the re-hardening of erosion lesions, but could not diminish enamel hardness loss. Therefore, there is no consensus regarding the effectiven

5. SHEEP AS AN EXPERIMENTAL MODEL FOR BIOMATERIAL IMPLANT EVALUATION
ABSTRACT Objective: Based on a literature review and on our own experience, this study proposes sheep as an experimental model to evaluate the bioactive capacity of bone substitute biomaterials, dental implant systems and orthopedics devices. The literature review covered relevant databases available on the Internet from 1990 until to date, and was suppleme

6. Effects of probiotic fermented milk on biofilms, oral microbiota, and enamel
The aim of this study was to evaluate in vitro and in vivo the effects of 2 brands of probiotic fermented milk on biofilms, oral microbiota, and enamel. For the in situ experiment, ten volunteers wore palatine devices containing four blocks of bovine dental enamel over 3 phases, during which 20% sucrose solution, Yakult® (Treatment A), and Batavito® (Treat

7. Changes in irradiance and energy density in relation to different curing distances
The present study aimed to assess the influence of curing distance on the loss of irradiance and power density of four curing light devices. The behavior in terms of power density of four different dental curing devices was analyzed (Valo, Elipar 2, Radii-Cal, and Optilux-401) using three different distances of photopolymerization (0 mm, 4 mm, and 8 mm). All

8. Mouthrinse recommendation for prosthodontic patients
Different reasons can contribute to classifying dental prosthesis wearers as high-risk individuals in relation to dental biofilm accumulation. These include a past history of oral disease, age and additional retentive areas. Other common complaints include inflammation and halitosis. Moreover, prosthesis replacement and prosthetic pillar loss are generally a

9. Instrumentos aplicados en la evaluación de la voz en profesores: estudio bibliográfico
The purpose of this study is to conduct a literature review focused on the instruments used to assess an objective and qualitative voice of teachers. A bibliographic review of the publications listed in PubMed and Scielo over the past 5 years, was performed which were connected with the evaluation of voice teachers. The instruments used in the 15 articles fo

10. AvaliaÃÃo da reaÃÃo de crianÃas submetidas à anestesia odontolÃgica local com seringa convencional e com desenho externo modificado / Evaluation of the reaction of children anesthetized with a traditional syringe and a modified syringe
Despite advances in Odontology, fear and anxiety regarding dentistry still affect a large number of people who, because of their fears, fail to seek treatment; this can result in low levels of oral health. The physical appearance of the instruments used by dentists seems to be a major cause of such fear and anxiety with regard to dentistry. The anesthetic sy

11. Programmatic actions in oral health: coping with social inequities
Inequities are health imbalances that are avoidable, unfair and unnecessary. Studies on health inequities address the need for emergency care related to oral-dental lesions from external causes, toothache or prevalence of oral lesions, taking into account the differences between individuals and/or populations in terms of risk conditions to acquiring disease

12. Fabricação de microeletrodos para aplicações em microscopia eletroquímica de varredura / Fabrication of microelectrodes for applications in scanning electrochemical microscopy
In this study, platinum microelectrodes were fabricated with a Micropipette Puller and used in Scanning Electrochemical Microscopy (SECM) to obtain information on the acid erosion of tooth enamel. The sealing and polishing of the active area of the fabricated devices are considered critical steps in the construction process, hence a vacuum pump was used to e
