Ameloblastoma is characteristically considered to be a benign but locally aggressive and infiltrative odontogenic tumor with high recurrence rate. Because of its invasive nature, the rates for ameloblastoma post treatment remains high. Recurrence also seems depend on histological type modalities used. Curettage alone reported have led 90% rate mandibular tumors 100% maxillary in literature. In ...

statement of problem: currently there are three recognized theories about the diameter of prepared dowel space in endodontically treated teeth. diameter of the dowel is commonly contributed to the root fracture. purpose: this study used a 3 dimensional (3d) finite element method to predict stress distribution in endodontically treated central maxillary tooth with cast post and core with various...

Wireless communication technology adopting electromagnetic waves in an unlicensed spectrum, such as visible light, for has attracted wide research efforts. Visible light (VLC) utilizes a medium to transmit signals but faces limited bandwidth and low data rate, which is caused by the intrinsic characteristics of LEDs. This paper first studies mathematical model its effect on transmitted then ana...

Here, we present a longitudinal analysis of two patients who recovered from COVID-19 more than 8 months prior but showed persistent serological detection anti-SARS-CoV-2 IgM. We still do not know the exact reason for this prolonged persistence IgM in these patients. To our knowledge, are first reports context SARS-CoV-2 infection and point to need no longer using as diagnostic criterion acute o...
