Xylanase pretreatment was used to improve the chlorine dioxide bleaching of bagasse pulp. The pulp was pretreated with xylanase, which was followed by a chlorine dioxide bleaching stage. The HexA content of the pulp and the AOX content of the bleaching effluent were measured using UV-Vis and GC-MS methods, respectively. The results showed that a good correlation occurred between HexA and kappa ...

This study was conducted to observe the response of dogs' dental pulp to white mineral trioxide aggregate (MTA) when used as pulp capping material. The pulp of 15 dogs' teeth was experimentally exposed and capped with white MTA. The animals were sacrificed two months later and the specimens were prepared for histomorphological study. The pulp capped with white MTA showed a healing process with ...

Freshwater algal biomass and orange and lemon peels were assessed as tissue paper pulp supplements. Cellulose and hemicellulose contents of algal biomass were 7.1% and 16.3%, respectively, whereas for citrus peels cellulose content ranged from 12.7% to 13.6% and hemicellulose from 5.3% to 6.1%. For all materials, lignin and ash content was 2% or lower, rendering them suitable for use as paper p...

Tooth pulp atrophy occurs with increasing age. An age estimation procedure using dental cone beam computed tomography (CBCT) imaging was developed. Clinical dental CBCT images of 60 patients (aged from 20 to 80 years) were evaluated. The ratio of the cross-sectional area of the pulp cavity to the cross-sectional area of the tooth (pulp cavity ratio) was calculated. The pulp cavity ratio in the ...

Coronectomy is a procedure that intentionally spares the vital root after removal of the crown of the lower third molar to avoid damage to the inferior alveolar nerve. Vital pulp therapy is one option for managing exposed pulp tissue to reduce the risk of pulpal inflammation or necrosis. Among various dental materials, mineral trioxide aggregate (MTA) has been successfully used for vital pulp t...

Josh has fractured his tooth and exposed the pulp. Although repairing the injury is the immediate problem, ensuring that the tooth will continue to thrive is the real challenge. Understanding the impact of trauma on the pulp and the importance of pulp vitality to sound tooth development is essential for optimum patient care. Endodontics can offer a unique perspective. Endodontic therapy general...

raft pulp i s manufactured in the United States from nearly all commercially availK ble wood species. About 55 million tons per year are manufactured, 30 million of which are bleached and used mostly for printing and office papers and tissue products. Some kraft pulp is exported, and significant quantities are imported, mostly from Canada and South America. Pulps manufactldred by sulfite, mecha...

BACKGROUND Different methods have been used in order to isolate dental pulp stem cells. The aim of this study was to study the effect of different types of pulp treatment during isolation, under 3% O2 conditions, in the time needed and the efficacy for obtaining dental pulp stem cells. MATERIAL AND METHODS One hundred and twenty dental pulps were used to isolate dental pulp stem cells treatin...

 Dental Pulp Stem Cells (DPSCs) can be found within the cell rich zone of dental pulp. These stem cells, under specific stimuli, differentiate into many cell types which have wide therapeutic applications.   The dental stem cells are derived from both deciduous and permanent teeth. The viable dental stem cells are very simple to collect, without any mortality and morbidity. Dental pulp stem c...

This study compared the effects of drying on beet pulp with and without added molasses by measuring the in sacco digestibility and composition including ®ber polysaccharides and minerals. Beet pulp was sampled before and after the addition of molasses from four different sugar processing plants within California. These samples were sub-sampled and then sun-, freeze-, or airdried. The percentage...
