    CONCORDANCE OF THE VESTIBULAR BONE THICKNESS AT THE LEVEL OF POINT A BETWEEN TELERADIOGRAPHY AND CONE BEAM COMPUTED TOMOGRAPHY
    (Universidad de Concepcion, 2023-04) Vergara, Carolina; Espinoza, Sebastián; González, Paulina; Martens, Camila; Rojas, Patricio; Córdova, Pedro
    Objective: The aim of this study was to determine the concordance of the vestibular bone thickness measured at the level of point A between Teleradiography and Cone Beam Computed Tomography (CBCT). Materials and Methods: This study consisted of a cross-sectional analytical design of concordance that evaluated the teleradiographies and CBCTs of 32 patients. The measurements were performed by three evaluators, specialists in orthodontics. Two of them measured the CBCTs and one evaluated the teleradiographs. The concordance of both tests was determined using the Concordance Correlation Coefficient. Results: When evaluating the value of the vestibular bone thickness at the level of point A between the CBCT and the teleradiography, it was observed that the mean value of the absolute difference between the two was 0.9540.74, 95%CI [0.68–1.22], being statistically significant (p=0.0027). When the concordance between both tests was analyzed, it was observed that it was poor (CCC=0.204 95%CI [0.014–0.394]), although statistically significant (p<0.00001). Conclusions: It was possible to conclude that there is no concordance in the measurement of the vestibular bone thickness at the level of Point A between the Teleradiography and the CBCT. © 2023.

    Pharmacological subjectifications: Attention deficit disorder, psychostimulants and school practices in two schools in santiago, chile
    (Athenea Digital, 2019) Navarro, Sebastián; Rojas, Patricio
    This article advances a material-semiotic approach in order to think with Attention-deficit hyperactivity disorder (ADHD) and the use of psychostimulant medication. Drawing from an ethnography centered around the practices enacted in two schools in Santiago, we argue that a pragmatic, relational and posthuman approach extends the analysis to different processes and dynamics about how children diagnosed with ADHD, medication, their peers, teachers and others human and non-human actors co-affect each other, thus enacting particular versions of the diagnose and of the medication's effects. Therefore, we argue for the need to relocate the discussion to avoid binaries that have trapped the reflections about how children affect and are affected by biomedical knowledges and "psy" practices. Particularly, we question the idea that subjectivity and psychostimulants are forcefully antagonist agents, since in practice, they both co-exist, co-affecting each other, producing creative and emergent elements, as revealed by our fieldnotes and ethnographic interviews. © 2019 Universitat Autonoma de Barcelona.
