An In Vitro study to evaluate and compare the flow property of different commercially available zinc oxide eugenol impression materials

Abstract

Introduction:Impression making is one of the most important steps in prosthodontic rehabilitation of edentulous patients. Zinc oxide eugenol (ZOE) impression paste is the most commonly used material for complete denture wash impression due to its cost-effectiveness and ease of manipulation, while providing the advantage of ability to record fine minute tissue details. Rheological property like flow is a critical factor influencing the success of any impression material, especially in intraoral conditions. Therefore, with so many brands of commercially available impression materials flooding the markets, the aim of this study was to evaluate and compare the flow property of four commercially available ZOE impression materials under simulated intraoral condition.Materials and Methods:The testing method used was according to the American Dental Association (ADA) specification no. 16 for ZOE impression pastes.Results:At room temperature, maximum flow was seen with Denzomix followed by Dental Product of India (DPI), Neogenate, and Cavex in descending order, respectively, at 30 s, 1 min, and 10 min of load application. At 37°C in saliva, maximum flow was seen with Denzomix followed by Neogenate, DPI, and Cavex in descending order, respectively, at 30 s, 1 min, and 10 min of load application. Of the four ZOE impression pastes, only the flow of Cavex was considerably less than ADA specified value.Interpretation and Conclusion:Results obtained from this study showed that there is considerable variation in the flow values of different commercially available ZOE impression materials. Change in temperature and presence of saliva had a significant influence on the flow of ZOE impression materials.

An in vitro study of a custom-made device for thermoregulation of the mixing slab on the setting properties of zinc oxide eugenol impression paste

“…This could be attributed to the incorporation of water at 10°C and higher activation energy at 40°C and 50°C, leading to a rapid increase in viscosity, thus, limiting the spread of the material under load. [ 23 24 ] However, better consistency was observed at 40°C and 50°C compared to 10°C. Although the material showed a faster setting, an increase in the consistency can be attributed to the plasticizing component such as thermoplastic substances present in the material.…”

Analysis of Role of Turmeric in Management of Alveolar Osteitis

“…Curcumin had no critical impact on quercetin-actuated atomic DNA harm, lipid per oxidation and protein corruption and along these lines has the one of a kind capability of going about as both master and cancer prevention agents, contingent upon the redox condition of their organic condition. Broad in vitro and in vivo testing has demonstrated that turmeric restrains synthetically incited epidermal ornithine decarboxylase action, epidermal DNA union, and the advancement of skin tumors in mice 16 .…”
