Resin Cementation of Lithium Disilicate Ceramic: A Microtensile Bond Strength Evaluation.

Objective: The objective of this study was to evaluate the resin-ceramic adhesion of a long-carbon-chain silane (LCSI)-containing resin cement.

Methods: Polished lithium disilicate ceramic discs were etched with hydrofluoric acid and randomly assigned into four groups; (PSAP), cemented using a silane-free resin cement with no prior priming; (PSAP-S), primed using a silane-containing primer before cementation using a silane-free resin cement; (PSAU), cemented using a LCSI-containing resin cement with no prior priming; (PSAU-S), primed as for the group (PSAP-S) and cemented using a LCSI-containing resin cement. The cemented blocks were sectioned into microbeams.

The clinico-pathological profile of non-Hodgkin's lymphoma in Aseer region of Saudi Arabia.

Objective: Non-Hodgkin lymphomas (NHL) are a group of neoplastic lymphoproliferative disorders, in which, its clinical spectrum, primary extra nodal variety, histopathology and Immunohistochemistry, remain lacking in Saudi Arabia. We aimed to assess the clinicopathologic patterns of NHL and the utility and diagnostic role of IHC immunophenotyping.

Results: Patients > 60 years of age had the highest incidence of NHL; male: female ratio was 1.
