- Annual Plan for use of funds to the Research Infrastructure Maintenance of FOP - Unicamp, 2020/2021, AP.RT.INST
Abstract
FOP currently has seven Graduate Programs. At the last evaluation by CAPES, corresponding to the four-year period of 2014 - 2017, four programs of our School received grades of Excellence for Graduate programs, two were 6 and two 7. This performance leaves FOP in a very comfortable position, considering Graduate Courses. From all Brazilian Graduate Courses with excellence grades (CAPES 6 …

- Determination of lower dose protocols with suitable image quality for an off-axis geometry computed tomography unit, BP.PD
Abstract
Although dental computed tomography exams offer a relatively low radiation dose to the patient, substantial evidences regarding stochastic effects of ionizing radiation indicate that even small doses may induce effects such as carcinogenesis. Therefore, exposure parameters should be adjusted keeping radiation dose as low as diagnostically acceptable. The aim of this study is to determine …
- Effectiveness of algorithms artifacts reduction in tomographic images, BP.PD
Abstract
The use of advanced methods such as cone beam computed tomography may help decision making in the diagnosis of the bucomaxillofacial region. However, the literature shows reduced accuracy of this imaging modality in the presence of high-density materials, due to the interference of artifacts. The application of algorithms called metal artefact reduction (MAR) has been suggested to minimiz…
- ASSESSMENT OF DENTAL RESORPTION OF THE SECOND MOLARS ASSOCIATED WITH THIRD MOLAR IMPACTION USING FINITE ELEMENT ANALYSIS, BP.PD
Abstract
Impacted third molars can lead to several symptoms and pathologic conditions; and among them is the root resorption of adjacent second molars. It is well believed that the resorption occurs as consequence of the pressure caused by the impacted third molar. However, there is a lack of scientific evidence to support this theory. Finite element analyses are important tools in dental research…

- Optimization strategies in CBCT thought development of institutional diagnostic reference levels of radiation dose and assessment of the influence of a narrow off-axis geometry computed tomography unit in image quality and radiation dose, BE.EP.PD
Abstract
Although cone beam computed tomography (CBCT) exams offer a relatively low radiation dose to the patient, substantial evidence regarding ionizing radiation's stochastic effects indicates that even small doses may induce effects such as carcinogenesis. Therefore, exposure parameters should be adjusted, keeping the radiation dose as low as diagnostically acceptable. Increasingly, CBCT syste…
- Validation of a metal artefact reduction algorithm in CBCT images of root filled teeth: a clinical study, BE.EP.PD
Abstract
Image quality of Cone Beam Computed Tomography (CBCT) reconstructions is seriously compromised when metals are present in the scanned volume generating some artefacts. Shadows and streaks mask both the metal objects and the anatomical structures in the vicinity, thus prejudicing or even invalidating diagnosis. One of the possible solutions to reduce the artefacts and thus significantly en…
