Öğe Comparison of conventional and digital radiography systems with regard to radiopacity of root canal filling materials(2012) Akcay I.; Ilhan B.; Dundar N.Aim To compare the radiopacity of five root filling materials as measured on digitized E-speed films, storage phosphor plate and CCD sensor images. Methodology Radiopacity of Resilon cones and Epiphany, MM-Seal, EndoREZ and AH Plus sealers were investigated. Ten acrylic plates were prepared and filled with the materials. Samples were radiographed together with samples of dentine and an aluminium stepwedge. Images were obtained using E-speed films, Digora storage phosphor plates and Schick CDR CCD sensor. Conventional radiographs were digitized using a desktop scanner. Mean grey values of the materials, stepwedge and dentine were measured using the histogram analysis function of Photoshop 7.0. A graph of radiographic density versus thickness of the aluminium was drawn for each image from which the radiographic densities of the materials were determined in relation to the aluminium thickness. The mean was calculated, and the data were analysed using repeated measures anova and Bonferroni tests (P<0.05). Results There were significant differences between different imaging modalities (P=0.018) and root filling materials (P<0.001). A statistically significant interaction between imaging modality and material was also observed (P<0.001). All materials had radiopacity above 3mm of aluminium regardless of the imaging technique. The radiopacity of Resilon and Epiphany was significantly higher on digital images compared with digitized E-speed film images (P<0.001). Conclusion The choice of imaging system may effect radiopacity measurements. It is possible that radiopacity as recorded on traditional or digitized films is not indicative of the radiopacity as recorded on a digital sensor. © 2012 International Endodontic Journal.Öğe Oral health in older adults: current insights and tips(Pacini Editore Srl, 2024) Bolukbasi G.; Dundar N.The aging process intricately intersects with oral health, necessitating a meticulous focus on the preservation and augmentation of well-being in the elderly. This demographic frequently contends with dental issues such as dental caries, periodontal problems, tooth loss, and an esca-lated susceptibility to severe oral conditions, notably oral cancer. The compounding factors of cognitive impairments and chronic illnesses exacerbate oral health challenges, further complicated by the pharma-cological interventions they undergo. The ongoing global demographic transition towards an aging populace engenders apprehensions, particularly in densely populated regions and emerging economies, where healthcare infrastructures may confront limitations. The advent of the COVID-19 pandemic has exerted a profound impact on healthcare systems, permeating into oral health services. The elderly, disproportionately susceptible to severe manifestations of the virus, grapple with heightened apprehension and reluctance to pursue healthcare, encompassing oral care. Prolonged social isolation im-posed by lockdown measures contributes to mental health ramifications, discouraging their engagement with oral healthcare services. This discourse underscores the pivotal significance of oral health in the elderly, propounding the necessity for targeted interventions and meticulously recalibrated strategies tailored to their distinctive needs. In the trajectory of this imperative undertaking, collaborative alliances among healthcare practitioners, policymakers, and communities assume paramount importance. Sustained research endeavors, coupled with synergistic partnerships with academic institutions, are imperative for the continual refinement of oral health interventions for the aging de-mographic, thereby fostering enhancements in their holistic well-being. © by Società Italiana di Gerontologia e Geriatria (SIGG).
