background: the biocompatibility of resin-modifi ed glass ionomers (rmgis) as a lining material is still under question. the present study evaluated the response of the pulp-dentin complex following application of resin-modifi ed glass-ionomer cement, calcium hydroxide and conventional glass-ionomer in deep cavities prepared in human teeth. materials and methods: in this controlled clinical tri...

A Comparison of Drug Effects upon the Jaw Jerk Response to Electrical Stimulation of the Tooth Pulp in Dogs and Cats. C. L. MITCHELL 1 The Effects of Morphine, Pentobarbital, Pentazocine and Nalorphine on Bioelectrical Potentials Evoked in the Brain Stem of the Cat by Electrical Stimulation of the Tooth Pulp. ROBERT N. STRAW AND C. L. MITCHELL 7 Analysis of Individual Rabbit Olfactory Bulb Neur...

Maintaining deciduous teeth in function until their natural exfoliation is absolutely necessary. Vital pulp therapy (VPT) is a way of saving deciduous teeth. The most important factors in success of VPT are the early diagnosis of pulp and periradicular status, preservation of the pulp vitality and proper vascularization of the pulp. Development of new biomaterials with suitable biocompatibility...

The theory of demand and supply implies a positive relationship, or ‘‘price transmission’’ between the prices of products at different stages of manufacturing. This relationship was investigated with quarterly prices of softwood stumpage in the US South, and national prices of forest products, from 1977 to 2002. All prices, net of inflation, were found to be nonstationary and there was no evide...

INTRODUCTION Vital pulp therapy is a major contributor in the preservation of primary dentition after caries affliction. Introduction of mineral trioxide aggregate (MTA) has revolutionized such treatment. AIM The aim of our study was to evaluate and correlate the effects of MTA clinically and radiographically on pulpotomized primary molars till their exfoliation or extraction followed by hist...

Xylan extracts from southern US hardwood were used for the adsorption of both hardwood and softwood pulp. Pulp beatability and physical strength properties were determined and compared with those of the conventional Kraft pulp and pre-extracted modified Kraft pulp. The results indicated that hemicelluloses adsorption greatly improved pulp beatability. Compared to conventional Kraft pulp, a sign...

The purpose of this study was to evaluate the effects of aminoguanidine (AG) as a selective inhibitor of inducible nitric oxide synthase (iNOS) on the degree of inflammatory response in periapical lesions in the canine teeth of cats. Root canals from 52 cat canine teeth were exposed to the oral cavity and sealed after 7 days. One day before pulp exposure, cats were administered either AG (exper...

Dehydrated citrus pulp and citrus pulp-protein supplements were evaluated as potential supplements for a preconditioning program. The supplements compared were no supplement, citrus pulp alone, citrus pulp with urea, and citrus pulp with added UIP. Supplemented cattle produced greater gains than unsupplemented cattle. Citrus pulp with added UIP produced the greatest ADG (0.95 lb/hd/d) whereas c...

Thermophilic mannanase from the Bacillus sp. MG-33 was applied on wheat straw-rich-soda pulp to evaluate its bleaching potential. Optimum conditions for bio-bleaching of pulp were found as, mannanase 3Ug -1 of pulp at pH 6.5 and temperature 65oC that enhanced the brightness by 30% and reduced the kappa number by 20% within 2h. Tear index (1.1, points) and burst index (0.02, points) were also im...
