Facultad de Medicina SX /S X Cytotoxicity of Dental Alginates Citotoxicidad de Alginatos Dentales. The aim of this study was to assess the cytotoxicity of alginates for dental applications. Fourteen different alginates were assessed: Jeltrate, Jeltrate Plus, Jeltrate. Actuamos sólo en el sector mayorista y principalmente en el ramo dental ; para lo cual disponemos de los registros e inscripciones necesarios que son.

The samples were kept in contact with culture medium during this 2-minute period, and xentales supernatants were then put in contact with the cells. Alginates Control Groups Jeltrate cgroups. Cytotoxicity of titanium dioxide nanoparticles in mouse fibroblast cells.

Citotoxicidad de Alginatos Dentales

The material used in the positive control ventales was a non-ionic surfactant Tweena toxic agent to biological membranes Rege et al. This time was obtained at the moment when the material stopped being sticky or adherent, and it is of critical importance because it determines the time available to mix the material, fill the impression tray and place it in the patient’s mouth by the dentist.

Walter de Gruyter, Berlin, Assessing the Cytotoxity of the Materials. The alginates obtained with the process selected produced a range of products with viscosities from 50 to mPa s sodium alginate and 48 to mPa s potassium alginate.

Cytotoxicity evaluation of Activ GP and Resilon cones in vitro. In this way, if appropriate quantities of potassium alginate, calcium sulfate and trisodium phosphate are mixed with water, the following reaction takes place: The two-minute evaluation adopted in this study was based on the maximum time in which alginate is left in contact with the oral mucosa during the impression procedure, as recommended by the manufacturer.

Conversely, Samuel et al. Application of some algal polysaccharides in biotechnology. In the present study, the cytotoxicity of dental alginates was assessed through cytotoxic tests performed with mouse fibroblast L cells, a method largely used in several works evaluating the cytotoxicity of materials for use in dentistry Alcaide et al.

It should also be emphasized that a successful clinical dentistry does not involve the technique mastery only, but also requires application of biosecurity norms and attention to the local and systemic consequences produced by dental materials being used.

Marco DonadioJ. Pilot plant scale extraction of alginates from Macrocystis pyrifera. The use of alginates in dental impression materials is based on the aqueous reaction between fentales sparingly soluble calcium salt usually calcium sulfate dihydrate and an alginatoe. The compressive strength within a given formulation varied with the type of alginate used. After adequate homogenization, the alginate was inserted into silicon rings 4 mm diameter x 4 mm height until full gelification Fig.

The loss modulus G” represents the viscous behavior of the formulation. Alginates with high content of guluronic acids characteristically yield materials with high gel strength. Alginates Search for additional papers on this topic. That is, this substance may not be toxic enough to kill the cells but can inhibit cell growth, affecting at least the normal cell function. In conclusions based on the results obtained, one can conclude that all alginate materials were found to be potentially toxic to cells.

Recibido en octubre de ; aceptado en octubre de Alginate is undoubtedly one of the most accepted materials used in dentistry. In all cases, the gels did not exhibit linear viscoelastic behavior and as the strain percent increased, a partial breakdown of the elastic structure occurred. Table 2 shows the quality profiles of sodium and potassium alginates extracted from M. Also, it could be improved by combining the use of modifiers such as magnesium oxide, potassium sulfate, sodium silicoflouride and other types of diatomaceous earths.

Cytotoxicity of dental alginates. Quantitative analysis of potentially toxic metals in alginates for dental use. Fourteen different alginates were assessed: By clicking accept or continuing to use the site, you agree to the terms outlined in our Privacy PolicyTerms of Serviceand Dataset License. Three control groups were also used in this study: The storage modulus represents the elastic behavior of the gel in the dental impression material prepared. However, many substances such as zinc, barium, cadmium, lead silicates, and fluorides are added to their formulations in order to improve the physical, chemical, and mechanical properties, being a cause of concern in terms of toxicity de Freitas, The chemical composition of the alginates can greatly affect the gel strength.

The objective of this research was to produce sodium and potassium alginates from M. With regard to cell viability, Jeltrate Plus was the material showing the highest percentage of viable cells compared to other groups, followed by Hydrogum The loss modulus values G” decreased with the increase in strain percent.

At the present time in Mexico, M. Production of dental impression material using sodium and potassium alginates. Cytotoxicity evaluation of Activ GP and Resilon cones in vitro.

Seven grams of each dental impression formulation table 1 were mixed with 18 mL of distilled water for 1 min.

The effect of these proposed modifications will be discussed in another paper. As expected, a low cytotoxicity was observed and no statistical difference found. Sodium and potassium alginates are hydrocolloid materials commonly used in dental impressions. One of the quality characteristics of the alginates is their calcium dentlaes. The cell culture was supplemented with 2 mM of L-glutamine Sigma, St.
