cytotoxic effects of obturation materials were tested in presence and absence of endotoxin on human monocytes in vitro.human monocytes from thp-1 cell line were cultured. three millimeters from the tip of each resilon and gutta percha points were cut and directly placed at the bottom of the culture wells. cultured cells were exposed to gutta percha (groups g1 and g2) and resilon (r1 and r2). te...

As part of a large retrospective study of the durability and lifespan of 2229 restorations in primary molars of 226 pediatric patients attending a dental school clinic, the histories of first-placement stainless steel crowns were examined. The histories of crowned primary molars in 131 patients were followed for up to 9 years, computerized, and their durability assessed in terms of crown replac...

Amalgam is a wonderful restorative material that has been used in dentistry for over 150 years. Millions of people world-wide have at least one dental amalgam restoration, and have not suffered any adverse effects. It is easily placed, relatively cheap and durable.

Teaching programs in dental schools have a strong effect on the practice of dentistry, not only for recent graduates, but also for established clinicians, especially with respect to new techniques and concepts. The purpose of the study reported here was to assess the frequency and extent of the tea...

introduction: this in vitro study aims to evaluate the coronal and apical sealing ability of gutta-percha (gp) root filling used with either mineral trioxide aggregate (mta), new endodontic cement (nec) or ah26 as filler/sealers. materials and methods: forty eight single-rooted extracted teeth were selected, decoronated and then instrumented. samples were randomly divided into three experimenta...

The survival rates of restorations in primary molars were calculated after a retrospective examination of patients' dental records from a study population of 1,065 children. A random sample of 128 records showing information for 604 dental restorations was examined, coded, and analyzed by the life table method of survival analysis. The order of the survival rate of restorations from higher to l...

ith all of the excitement in the media concerning cosmetic dental makeovers and “spa dentistry,” it’s possible sometimes for dentists to lose our focus. The root of dentistry is still restorative treatment in the posterior regions to eliminate caries, repair fractures, and replace restorations whose warranties have long expired. This, after all, is the “bread and butter” of dentistry. There wil...
