Effects of low-dose ionizing radiation on the molecular pathways linking neurogenesis and autism spectrum disorders in zebrafish embryos.

Prenatal exposure to environmental factors may play an important role in the aetiopathogenesis of autism spectrum disorder (ASD). We aim to investigate the potential effects of low-dose x-rays from dental diagnostic x-rays on neurodevelopment and molecular mechanisms associated with ASD in developing zebrafish embryos. Zebrafish embryos were divided into four groups and exposed using a dental x-ray unit: control, 0.

Panoramic dental X-ray exposure leads to oxidative stress, inflammation and apoptosis-mediated developmental defects in zebrafish embryos.

Panoramic x-ray units are widely used in dental radiodiagnostics. Patients are exposed to relatively low radiation doses with panoramic imaging, but considering lifetime frequency of exposure, even a small risk can have serious health consequences. Our aim was to assess the effects of panoramic x-rays at two different exposure times on developing zebrafish embryos, focusing on oxidative stress, inflammation, apoptotic pathways, and development.

Radiological Associations between Posterior Edentulism and Condylar Bony Changes: A Retrospective Study.

This retrospective study aimed to investigate the relationship between posterior edentulism and condylar bone changes in patients aged 35-60 years. The CBCT images of 259 patients, including 131 posterior edentulous and 128 posterior dentulous patients, were analyzed to identify the types of condylar bone changes. The frequency of flattening, sclerosis, erosion, and reduced joint space was found to be higher in posterior edentulous patients.

Association between second mesiobuccal canal and apical periodontitis in retrospective cone-beam computed tomographic images.

This retrospective cone-beam computed tomography study aimed to investigate the possible associations of apical periodontitis (AP) with missed/unmissed second mesiobuccal (MB2) canals. MB2 canals and AP were investigated in 257 endodontically treated and 673 untreated maxillary molars, and the former were analyzed regarding missed/unmissed MB2 canals. The chi-squared test and odds ratio (OR) were used for statistics.

Associations between Periapical Health of Maxillary Molars and Mucosal Thickening of Maxillary Sinuses in Cone-beam Computed Tomographic Images: A Retrospective Study.

Introduction: This retrospective study aimed to assess the radiologic characteristics of the possible associations between mucosal thickening of the maxillary sinuses (MSs) and periodontal and anatomic conditions of healthy and diseased maxillary teeth.

Methods: The periapical health of the maxillary molars in cone-beam computed tomographic (CBCT) images from 50 patients (mean age = 40.60±14.

Attitudes and knowledge of paediatric dentists' on digital radiography and cone beam computed tomography.

Objective: To determine the frequency and reasons of digital radiography and cone-beam computed tomography usage among paediatric dental practitioners, and to assess their knowledge and need for specific education..

Methods: The cross-sectional study was conducted from January to July 2017 and comprised paediatric dentists present at the European Academy of Paediatric Dentistry Interim Seminar in Turin, Italy, and members of the Turkish Society of Paediatric Dentistry who did not attend the event.

Association between Oral Mucosal Lesions and Hygiene Habits in a Population of Removable Prosthesis Wearers.

Purpose: This prospective study evaluated the influence of self-reported prosthesis hygiene regimens and prosthesis usage habits on the presence of oral mucosal lesions (OMLs) in complete removable and/or partial removable dental (CRDP/PRDP) prosthesis wearers (PWs).

Materials And Methods: Between January 2009 and January 2011, the conventional oral mucosa of 400 consecutive PWs (252 women; 148 men), aged between 29 and 86 years, were examined clinically. Information was derived considering the type and age of the prosthesis, hygiene level, frequency and style of prosthesis cleaning, overnight prosthesis use, storage conditions, and systemic diseases.

Improvement of oral health knowledge in a group of visually impaired students.

Purpose: The aim of this study was to evaluate the effectiveness of a repeated oral health education programme on oral health knowledge and hygiene of visually impaired students.

Materials And Methods: The study was conducted at one of the two visually impaired boarding schools of Istanbul, Turkey. The number of subjects was 65, comprising 28 totally and 37 partially visually impaired students between 7 and 17 years of age.
