Pectin is used in a number of foods as a gelling agent, thickener, texturizer, emulsifier and stabilizer. Sugar-beet pulp, the residue left from sugar extraction, is a rich source of pectin. It was the purpose of this study to develop a procedure for the extraction of pectin from sugar-beet pulp and to improve the functional properties of this pectin for more potential uses. To extract pectin, ...
Introduction: Researchers have always been interested in the close and mutual relationship between the pulp and periodontal tissues. Although the effects of pulpal disease on periodontium have been well known, the clear relationship between periodontitis and pulp has not been documented . It seems that bacteria and inflammatory products of periodontitis can affect pulp through accessory canals,...
Corn stalk can be used as an alternative non-wood raw material to produce cellulosic dissolving grade pulp. In this work, the potential of corn stalk in the production of dissolving pulp (alpha-cellulose) was investigated. It was collect ed from a corn stalk farm of Kermanshah, Iran. The sequences of experimental work were: water and acid prehydrolysis at 160˚C for 30min, followed by Kraft pulp...
Background and purpose: Coronary artery disease is a major cause of mortality, morbidity, and disability in society and patients incur high expenditure on treatment. Pulp stones are ectopic calcifications of the pulp vessel walls, so, they can have similar pathogenesis as those of other organs and coronary atherosclerosis. The purpose of this study was to investigate the correlation between cor...
Background and Aims: The vitality pulp tests are necessary for diagnosis of pulpal disease and differentiation between endodontic and non-endodontic diseases. Thermal and electrical tests are conventional methods for evaluation of pulp vitality. The purpose of this study was to evaluate the effect of thermal changes on the tooth response to the electric pulp tester. Materials and Methods: In t...
Dental decay prevalence in the primary dentition continues to maintain high levels in the infant population, despite the efforts and advances that have been made in the field of oral health prevention programs [1]. This situation increases the possibilities of pulp involvement due to the presence of deep caries, leading pulp to an irreversible state, implying the need to perform a pulp treatmen...
Considering the ease of isolation and high expansion potential of pulp stem/progenitor cells isolated from wisdom and primary teeth they have been implicated as the most reliable autologous cell source in dental tissue engineering. Meanwhile, different isolation methods have remarkable impacts on the expansion potential of adult stem cells. In enzymatic digestion method extracted teeth as denta...
In order to examine the effects of increasing concentrations of beet pulp (lipogenic nutrient) substituted for barley grain (glycogenic nutrient) on productive performance, body condition score loss, and blood metabolites, 18 Holstein cows were used in a randomized complete block design. The cows were blocked based on parity. The cows were 171 ± 16 d in pregnancy, 2.76 ± 1.14 parity, and 289 ± ...
The regenerative potential of dental pulp is very limited in mature teeth. However, our improved understanding of pulpal inflammation and repair and improved dental materials and technologies make vital pulp therapy a viable alternative to root canal treatment. This article explores our knowledge in this regard and the future potential of saving or even regenerating the pulp as a routine dental
AIM The purpose of this paper is to consider evidence for the early involvement of the pulp in primary molars following a proximal caries attack and to consider the evolution of ferric sulphate as the possible alternative to formocresol for pulp therapy in primary molars. Concerns have been expressed over the wisdom of using products containing formaldehyde in children and alternatives should b...
