The effects of barium sufate and iodide compound on the characteristics of dental acrylic resins

Abstract

Aspiratin or swallowing foreign bodies is a common occurrence. If they are wholly or partly radiopaque, their localization in and progress through the gastrointestinal tract can be more effective. Of the dental origin foreign materials swallowed, the most common things are fragments of anterior maxillary partial denture. But the radiopacity of denture base resins is not sufficient to determine the location of the objects. The purpose of this study was to develop a radiopaque dental acrylic resin, which has clinically detectable radiopacity with minimal change of mechanical properties and color. the radiopacity, color change (CIE E) and microhardness of acrylic resins were determined after mixing barium sulfate or iolide compound. Thermocycling course was conducted to deter mine the change of characteristic of resins after using for a long time I the mouth. Five or ten percent of barium sulfa te to total weight of cured material was mixed with heat curing dental acrylic resin or chemically curing orthodontic re sin. In the case of iodide compound, the mixing ratio was two or three percent. After mixing the high radiopaque material s, resin was cured to 20X20X2 mm plate, polished with 600 sand paper and finally polished with Microcloth (Buehler). T  More>>

The purpose of this study was to develop a radiopaque dental acrylic resin, which has clinically detectable radiopacity with minimal change of mechanical properties and color. the radiopacity, color change (CIE E) and microhardness of acrylic resins were determined after mixing barium sulfate or iolide compound. Thermocycling course was conducted to deter mine the change of characteristic of resins after using for a long time I the mouth. Five or ten percent of barium sulfa te to total weight of cured material was mixed with heat curing dental acrylic resin or chemically curing orthodontic re sin. In the case of iodide compound, the mixing ratio was two or three percent. After mixing the high radiopaque material s, resin was cured to 20X20X2 mm plate, polished with 600 sand paper and finally polished with Microcloth (Buehler). T he specimens were thermocycled in 5 and 55 degree distilled water for 2,000 times, and the measurement of radiopacity, color and Vickers hardness was repeated every 500 times thermocycling. The radiopacity of specimens on the X-ray films was measured with densitometer (X-rite). The color change was determined with differential colorimeter (Model TC-6FX, Tokyo Denshoku), and the Vickers hardness number was measured with microhardness tester (Mitsuzawa). The following results were obtained : 1. All the three variables, the kinds of acrylic resins, the mixing or the kinds radiopaque materials and thermocycling , had combined effect on the radiopacity of the dental acrylic resins (p<0.01). 2. The two variables, the mixing or the kinds of high radiopaque materials and thermocycling, influenced on the radiopacity of the dental acrylic resins (p<0.01). but the kinds of acrylic resins did not influence on the color change of mixed dental acrylic resins (p<0.05) 3. Each of the three variables, the kinds of acrylic resins, the mixing or the kinds of high radiopaque materials and thermocycling, influenced on the radiopacity of dental acrylic resins (p<0.01). 4. The high radiopaque materials used in this study did not yield clinically usable radiopacity, and the color change was great after mixing those materials.}
