The biological properties of Scotchbond as a dentin-bonding agent were assessed in cytotoxicity tests, subcutaneous implantation, in an acute vital microscopically controlled test on rat incisors and in an usage test on human teeth. The persistent moderate reactions in human teeth in the test period over 90 days, the strong toxicity in the initial and(More)
The effects of calxyl, ZOE, zinc oxide without eugenol, and zinc oxide with an antibacterial substance (glutaraldehyde) were tested on perforated molar pulps of rats. All of the substances tested were found to lead to the same initial reactions (acute inflammation and partial necrosis). Calxyl and ZOE yielded unfavorable results. There was a negligible(More)
The biocompatibility of a fast setting glass-ionomer cement and of reference materials (zink-phosphate cement, silicate cement, ZOE, composite) was assessed in a comparative biological study. Cytotoxicity testing revealed 90% counted cell numbers after incubation for 96 hours. Subcutaneous implantation tests resulted in slight, moderate and severe(More)
The postpreparative pathophysiological reactions of the blood circulation are shown by vital microscopy examinations of the pulp of the incisors of living rats.--After twenty-four hours from the experimental preparation of cavities, functional changes are characterized by acutely inflammatory reactions. With the passage of time (seven-day check), the damage(More)
The vital-microscopic acute pulp test in rat incisors did not show any toxic effects of the light-curing composite material Lux-a-fill, independent of the remaining dentin thickness. The clinically controlled 2-year study of restorations of cavity class I, III, IV and V have yielded good results in the front teeth region. In addition to the clinical study a(More)
