The aims of this study were to evaluate the quality of indirect digitized radiographic images taken during endodontic procedures and to compare the measurements recorded with this technique to those obtained from conventional radiographs. Two-hundred conventional periapical radiographs taken at the undergraduate Endodontics Clinic of the Dental School of Bauru were digitized. The conventional and indirect digitized images were compared by three examiners as to the quality and accuracy of the measurements recorded during endodontic treatment, in canal length determination, gutta-percha adaptation, lateral condensation and final obturation. The conventional radiographs were observed on a film viewer, surrounded by a dark card, and measured with magnifying glass and a millimeter ruler; the indirect digitized images were evaluated on the Digora for Windows software, with free utilization of the bright/contrast tool. Unlike the conventional radiographic images, all indirect digitized images were considered as having a high quality. The distance between the filling material and the root apex was 0.117 mm larger, on average, for the Digora system (p<0.01). The measurements achieved by the investigated radiographic methods were clinically similar and they are thus equivalent. Changes in brightness and contrast of the images using Digora software improved the diagnosis.

Introduction: People with Parkinson's disease (PwPD) experience a wide range of motor and non-motor symptoms that have a significant impact on their health and quality of life. Effective care management for PwPD involves monitoring symptoms at home, involving specialised multidisciplinary care providers and enhancing self-management skills. This study protocol describes the process evaluation within a randomised clinical trial to assess the implementation and its impact on patient health outcomes of ParkProReakt-a proactive, multidisciplinary, digitally supported care model for community-dwelling PwPD.

The digital economy has significantly enhanced economic quality, and studying its implications on the environment can provide empirical support for policies that foster environment-economy coordination. This paper examines the impact of digital infrastructure on air quality, focusing on the mechanisms of public environmental attention and industrial development. It further analyzes heterogeneity in urban locations, degree of urbanization, and environmental regulation intensity.

Background: Two scientific and clinical challenges for treating cannabis use disorder (CUD) are developing efficacious treatments with high likelihood of uptake and scalability, and testing the clinical mechanisms by which treatments work. Because young adults experience more CUD than other age groups, a need exists to test the efficacy and hypothesized causal pathways of novel treatments for CUD. Text-delivered treatments have the potential to reach young adults by increasing access and perceived privacy.
