1. Evaluation of radiation protection conditions in intraoral radiology
Abstract Introduction: The dental radiology represents about 20% of human exposure to radiation in radio diagnostic. Although the doses practiced in intraoral dentistry are considered low, they should not be ignored due to the volume of the performed procedures. This study presents the radiation protection conditions for intraoral radiology in Curitiba - PR

2. Comparative clinical study of the effectiveness of different dental bleaching methods - two year follow-up
This study evaluated color change, stability, and tooth sensitivity in patients submitted to different bleaching techniques. MATERIAL AND METHODS: In this study, 48 patients were divided into five groups. A half-mouth design was conducted to compare two in-office bleaching techniques (with and without light activation): G1: 35% hydrogen peroxide (HP) (Lase P

3. Estudo in vitro da variação do pH de agentes clareadores e seu efeito sobre o desgaste e rugosidade superficial do esmalte bovino após escovação simulada / Variation of pH bleaching gels, wear and roughness of bovine enamel after tooth brushing abrasion test.
This in vitro study evaluated the variation of the pH of bleaching gels, roughness and the wear on bovine enamel, after various in office bleaching protocols and brushing. Ninety fragments of enamel, measuring 15mm x 5mm, were randomly divided into nine groups (n=10) according to bleaching procedure: G1: control; G2: 35% hydrogen peroxide (HP) (Whiteness HP,

4. X-ray beam qualities for dental radiology purposes / PadronizaÃÃo de qualidade de feixes de raios-X para uso em radiologia odontolÃgica
In order to establish characteristics or properties of equipment for diagnostic radiology, e.g. ion chambers and semiconductor detectors, calibration laboratories offer a set of well-defined radiation conditions, called X-ray qualities, which can be used for many Physics studies and medical purposes. These X-ray qualities can be determined in terms of: (a) X

6. Clinical evaluation of effectiveness for different techniques of extrinsic bleaching / Avaliação clínica de diferentes técnicas de clareamento de dentes polpados quanto à efetividade durante 12 meses
Objectives: This study was evaluated color change and stability and tooth sensitivity in patients submitted to different bleaching techniques. Methods: Forty five patients were selected according to inclusion/exclusion criteria and divided in five groups (n=15). A half-mouth design was conducted to compare two in-office bleaching techniques with the same pro

7. Development of ultrasonic waveguide for monitoring dental implant osseointegration / Desenvolvimento de guia de ondas ultra-sônicas para monitorar a osseointegração de implantes dentários
Available equipments for clinical assessment of dental implants monitor changes in stiffness but are not able to quantify the osseointegration level. Literature shows that the application of low-intensity pulsed ultrasound stimulates the healing of bone fractures and the bone ingrowth into implants pores, indicating that an ultrasonic waveguide could be used

8. Adverse effects on dental surgeons? health and its correlations with motor equipment use / Efeitos adversos na saúde de cirurgiões-dentistas e suas correlações com o uso de equipamentos motores
This study aimed to identify adverse effects reported by dental surgeons (DS) and correlate them to the use of motor equipment. We carried out a non experimental cross-sectional research with quantitative data analysis. The study involved 247 DS who work in Ribeirão Preto, Brazil. A self-applied questionnaire was used to assess the professionals. This instr
