    Effect of processing technique and coping thickness on fracture resistance of lithium disilicate copings

    Mohamed H. Riad , Jihan F. Younis , Hanaa H. Zaghloul
    Aim: The purpose of this in vitro study was to determine the optimum margin thickness which allows more conservative tooth preparation, thus giving space for the veneer material and to evaluate the effect of the processing technique on fracture resistance of IPS e.max® copings. Methods: Forty all lithium disilicate copings were divided into 2 equal groups according to the construction technique; twenty copings each (n = 20) per group. Each group was further subdivided into 2 equal subgroups according to the coping margin thickness; 0.5 mm and 0.7 mm (n = 10/subgroup). Two dies were prepared...

    Dilemmatic presentation of linear IgA disease: a case report

    Roopashri Rajesh Kashyap , Gopakumar R. Nair , Rajesh Shanker Kashyap
    Linear IgA disease is a rare blistering disease affecting the skin and less often the oral mucosa. This disease has a varied clinical presentation especially when the disease affects the oral mucosa. Certain drugs, autoimmune diseases, infection, chronic renal insufficiency, and malignancies have been implicated as the etiologic factors of this disease. The gold standard for diagnosis of linear IgA disease is direct immunofluorescence on fresh tissue. The immunofluorescence will demonstrate a homogeneous linear deposition of immunoglobulin A along the basement membrane. Multiple therapeutic...

    Effect of artificial accelerated aging on surface roughness and color stability of different ceramic restorations

    Tamer A. Hamza , Ahmed A. Alameldin , Ahmed Y. Elkouedi , Alvin G. Wee
    Aim: The purpose of the study was to evaluate the effect of artificial accelerated aging on surface roughness and color stability of three recently introduced CAD/CAM materials. The hypothesis was that artificial accelerated aging would have an effect on surface roughness and color stability of tested materials. Methods: A total of 21 ceramic discs were fabricated in this study, including translucent zirconia (InCoris TZI) and resin nano ceramic (Lava Ultimate) ceramic blocks for CAD/CAM and a set of bi-layered discs made of a zirconia CAD/CAM substructure (inCoris ZI) with VM9 hand-layered...
