A laboratory aerobic incubation study was performed during 18 weeks under controlled conditions to assess the effects of applying different doses of pulp mill inorganic wastes on the physical-chemical properties of an acid Dystric Cambissol. Three different inorganic wastes were tested - wood ash, dregs and grits, and an agriculture limestone was used as reference. Results showed that increasin...

The effect of time and pressure on the selective extraction of sugar beet pectin using steam pre-treatment on unprocessed Sugar Beet Pulp was evaluated using a design of experiments approach. This process gave the highest solubilisation of pectin oligomers at a relatively low pressure and longer time (5Bar, 24min), whilst leaving the majority of the cellulose fraction intact. This method of ste...

OBJECTIVES The purpose of this experimental study was to compare the disinfection efficacy of sodium hypochlorite and peroxygenic acid (Virkon) solutions for dental stone casts contaminated with microbial strains. MATERIALS AND METHODS A total of 960 spherical stone beads with a diameter of 10 mm were prepared and used as carriers of bacterial inoculums. They were individually inoculated by s...

In this study, two improved dental stones were used to fabricate master casts and dies. The tested fabrications were BegoStone (Bego Bremer, Goldschlägerei Wilh. Herbst GmbH and Co. Wilhelm HerbstStrabe 1 D 28359 Bremen Germany), Moldano (Heraeus Kulzer GmbH and Co. KG Gruner Weg 11 D-63450 Hanau Germany) and plaster of paris (BMT, PK 121 Sivas, Turkey). Together with the manufacturer’s values,...

This study was carried out to assess the quality of impressions sent to dental laboratories in Jordan. A sample of 136 impressions and stone casts were examined for technical errors in 35 laboratories that construct fixed partial dentures. They were sorted into these categories: unusable, unsatisfactory, acceptable or satisfactory The type of impression material and tray, opposing arch impressi...

There is an increasing demand for fibre rich food and food ingredients. In this study, pumpkin pulp, unripe banana pulp, unripe mango pulp and peel which are high in dietary fibre were processed into flour and substituted at 5% level for wheat flour in a composite flour crackers formulation. The control crackers comprised of 100% wheat flour. Sensory evaluation was conducted using a 9-point hed...

BACKGROUND Pulp stone, though of an unclear aetiology, is clinically common. It potentially poses procedural difficulty to the endodontist and may also be a marker of an underlying systemic condition. OBJECTIVES The study investigated pulp stone occurrence in adult restorative patients. It also highlighted the relationship between pulp stone and pristine posterior teeth, chronic periodontitis...

Dental caries is an infectious disease that causes tooth decay. The high prevalence of dental caries in recent humans is attributed to more frequent consumption of plant foods rich in fermentable carbohydrates in food-producing societies. The transition from hunting and gathering to food production is associated with a change in the composition of the oral microbiota and broadly coincides with ...
