Background/purpose: Studies suggested that presence and size of overhanging restoration margins play role in alveolar bone loss. The aim of this study was to determine the prevalence and distribution of overhanging approximal restorations, to evaluate the effect of presence and size of overhang on bone loss using cone beam computed tomography (CBCT) reformatted panoramic images, and to encourage the use of CBCT in retrospective studies on restorative dentistry.
Materials And Methods: CBCT images of 382 patients with approximal restorations were included in the study.
Background/purpose: Radiological examination is indispensable in the diagnosis and follow-up of cemento-osseous dysplasia (COD). The aim of this retrospective study was to describe a series of COD cases, identify the frequencies of COD subtypes, and investigate the demographic and radiological characteristics in relation to subtypes.
Materials And Methods: Cone beam computed tomography (CBCT) images/reports of patients with a diagnosis of COD were included in the study.
Aim: Increasing use of cone beam computed tomography (CBCT) for dentomaxillofacial diagnosis raises concerns about radiation dose which is known to be higher compared to conventional dental imaging methods. This retrospective study investigated the CBCT referrals in a Turkish paediatric subpopulation in terms of referring department, field of view (FOV),and findings.
Materials And Methods: A total of 8,880 CBCT images were reviewed retrospectively and images of paediatric patients (?14 years old) were selected.
Dental health care workers are subjected to various infectious disease agents that are present in patients' saliva and blood which make infection control and universal prevention methods indispensable to the dental practice given that some of these diseases cause loss of work and time for dental staff and patients; some of them cause serious morbidity; and some of them currently have a poor prognosis and no effective treatments. Although dental radiographic procedures are not invasive, and there are no incidents such as injuries caused by dental instruments, they are a potential infection source because of contamination with saliva and blood, and comprehensive infection control procedures also apply to the radiology clinic. In addition, contact with a large number of patients in dental schools and clinics in a short period of time, and the fact that radiographic procedures are performed in the same environment as other dental procedures in dental offices increase the significance of infection control in dental radiology.
