Análisis cuantitativo del hueso alveolar y palatino en las zonas de colocación de minitornillos utilizando CBCT
2022
OBJETIVOS: La estabilidad de los minitornillos está relacionada con la calidad y cantidad ósea existente en el complejo craneofacial. En este estudio se analizaron, tanto en el maxilar como en la mandíbula, los espacios interradiculares, la cortical ósea vestibular, la anchura del proceso alveolar, así como el espesor del hueso palatino y la densidad ósea de la cortical. Las mediciones se realizaron utilizando el CBCT y se analizó la correlación existente de las mismas con el patrón facial, la clase esquelética, la edad y el sexo de los sujetos. MATERIAL Y MÉTODOS: 129 CBCTs fueron seleccionados de pacientes pertenecientes a la Clínica Odontológica de la Universitat de València. Se realizar…

2015
Adisen, Mehmet Zahit/0000-0002-5493-8390; Yilmaz, Selmi/0000-0001-9546-6548; Yilmaz, Selmi/0000-0001-9546-6548; ATIL, Fethi/0000-0002-8286-4819 WOS: 000365269900009 PubMed: 26116844 Background: The aim of the present study is to evaluate the efficacy of CBCT in volume measuring using Stafne Bone Cavities (SBC) as an example. Material and Methods: The study was conducted with 14 subjects with SBC detected on panoramic radiographs. In order to evaluate lesions volumetric dimensions, CBCT images for each patient were captured. Files in Digital Imaging and Communications in Medicine (DICOM) format were transferred into a medical image processing program (ITK-SNAP 2.4.0) and volume in mm(3) of t…
Discrepancies between Mothers' and Fathers' Perceptions of Sons' and Daughters' Problem Behaviour: A Longitudinal Analysis of Parent‐Adolescent Agree…
1998
One hundred and ninety-eight adolescents and their mothers (N = 189) and fathers (N = 136) participated in a 4-year longitudinal study. Adolescent problem behaviour was assessed by the Youth Self-Report (YSR) and the Child Behavior Checklist (CBCL). In addition, parental stress and marital adjustment were determined. Results showed that mothers and fathers showed high agreement, especially about their daughters, whereas parents and adolescents showed little agreement. Agreement was higher for internalising than for externalising behaviours. In general, adolescents reported more symptomatology than their parents did. However, mothers' ratings of their children's behaviours were significantly…
Psychiatric symptoms in patients with post-H1N1 narcolepsy type 1 in Norway.
2019
Study objectives Several studies have reported psychiatric comorbidity in patients with narcolepsy type 1 (NC1). The primary aim of this study was to explore the extent of psychiatric symptoms in a cohort of Norwegian NC1 patients, most of whom were H1N1-vaccinated. We also wanted to explore possible causes of the psychiatric symptoms seen in NC1. Methods Cross-sectional study. Psychiatric symptoms were assessed by the Achenbach System of Empirically Based Assessment (ASEBA) Child Behavior Check List (CBCL) in children and by Adult Self Report (ASR) in adults. Results The mean (SD) total T-scores were 58.6 (9.2) for children and 57.0 (9.8) for adults, these being mainly driven by internaliz…
Juvenile ossifying fibroma of the maxillofacial region: analysis of clinico-pathological features and management
2021
Background The diagnosis and management of juvenile ossifying fibroma (JOF) remains a highly debated topic with paucity of studies with long-term follow-up, hence the aim of this study was to report on the clinico-pathological features and management of these neoplasms. Material and Methods A retrospective analysis was performed on all histopathologically confirmed JOF presenting at two tertiary hospitals in Cape Town, South Africa over a period of 39 years. Clinical, demographic, histopathological and radiological features were analyzed. Surgical methods were documented and a minimum post-operative follow-up of 12 months was a prerequisite. Results Seventeen patients met the inclusion crit…
Neuropsychological Profile, Emotional/Behavioral Problems, and Parental Stress in Children with Neurodevelopmental Disorders
2021
Background: The aim of our study was to trace a specific neuropsychological profile, to investigate emotional-behavioral problems and parental stress in children with Autism Spectrum Disorder Level 1/High functioning (ASD-HF), Specific Learning Disorders (SLD) and Attention Deficit/Hyperactivity Disorder (ADHD) disorders and to highlight similarities and differences among the three groups. Methods: We retrospectively collected the data from a total of 62 subjects with ASD-HF (n = 19) ADHD (n = 21), SLD (n = 22) and 20 typical development. All the participants underwent neuropsychological standardized test for the evaluation of cognitive profile (Wechsler Intelligence Scale for Children Four…
Adolescents with Neuropsychiatric Disorders during the COVID-19 Pandemic: Focus on Emotional Well-Being and Parental Stress
2022
(1) Introduction: The aim of our research was to explore emotional/behavioral changes in adolescents with neuropsychiatric conditions during the COVID-19 pandemic, and parental stress levels through a standardized assessment, comparing the data collected before and during the first months of lockdown. Moreover, an additional goal was to detect a possible relationship between emotional/behavioural symptoms of adolescents and the stress levels of their parents. (2) Methods: We enrolled 178 Italian adolescents aged between 12–18 that were referred to the Child Neuropsychiatry Unit of the University Hospital of Salerno with different neuropsychiatric diagnoses. Two standardized questionnaires w…
Bartotraumatic Blowout Fracture After Sneezing: Cone Beam CT demonstration
2013
Rarely a blowout orbital fracture is related to sneezing in patients with no history of trauma or sinus surgery. A case of barotraumatic, pure and isolated blowout fracture of the right orbit after sneezing diagnosed by CBCT is reported. A forty-year-old man complained sudden right diplopia after vigorous sneezing. On MRI a reduced size and an altered shape of the right maxillary sinus, a slightly increased vertical diameter of the right orbit, a round shape of the inferior rectus muscle on coronal sections, and a right maxillary haemosinus were observed. A strong peripheral enhancement of the maxillary sinus wall was evident. One week after the patient was submitted to a maxillofacial CBCT…
Accuracy and the role of experience in dynamic computer guided dental implant surgery: an in-vitro study
2019
Background To compare the accuracy of implant placement using the conventional freehand method and a dynamic navigation system; to assess the role of the surgeon’s experience in implant placement using these two methods. Material and Methods A randomized in-vitrostudy was conducted. Six resin mandible models and 36 implants were used. Two researchers with differing clinical experience (novice and experienced) placed implants using either the Navident dynamic navigation system (navigation group) or the conventional freehand method (freehand group). Accuracy was measured by overlaying the real position in the postoperative CBCT on the virtual presurgical placement of the implant in a CBCT ima…
Empirically Determined, Psychopathological Subtypes in Children With ADHD
2013
OBJECTIVE: The aim of this study was to empirically determine subgroups of ADHD defined by specific patterns of psychopathology. METHOD: A clinical sample of 223 children with ADHD, aged 5 to 14 years, was examined with the Child Behavior Checklist (CBCL). In addition, comorbid psychiatric disorders, psychosocial risk factors, and socioeconomic status were assessed. RESULTS: Cluster analysis of CBCL subscales yielded a solution with four distinct subgroups. While "externalizers" showed a high rate of comorbid oppositional defiant disorder (ODD) and conduct disorder (CD), "obsessive-compulsives" exhibited thought problems, low rates of comorbid CD, and high symptoms of inattention. "High psy…
