A connectivity model for assessment of HIV transmission risk in injection drug users (IDUs).

The purpose of this study was to produce models composed of mapping of connectivity networks of HIV transmission risk in injection drug users (IDUs). This methodology provided a novel approach and diagnostic tool for understanding HIV infection transmission risk and drug use in the typical niche of IDUs, i.e.

The political culture of healthcare: why substantial dental care in Canada is covered by government insurance only in Québec - lessons for the United States?

Surgical endodontic and retrograde procedures.

This article reviews the recent literature on endodontic surgery and root end filling materials. Root end filling materials have been studied extensively during the period of this review. The materials that have proved to consistently seal the apex in both leakage and success studies are the reinforced zinc oxide-eugenol cements such as IRM (The L.

Retrograde filling materials: a retrospective success-failure study of amalgam, EBA, and IRM.

A retrospective study was done to compare the success rates of teeth with three different root end filling materials. The materials studied were SuperEBA, IRM, and zinc-free high-copper spherical amalgam. Radiographs of 488 cases from two geographically distinct offices were used, with the recall period ranging from a minimum of 6 months to a maximum of 10 yr.
