TAPIA SILVA, R.; VALENZUELA ARANGUIZ, V.; ZAMORANO PINO, X. e BAENA AGUILA, R.. Heat Production Measuring in Autopolimerizing Acrylics. Av Odontoestomatol [online]. 2010, vol.26, n.2, pp.91-96. ISSN 2340-3152.
It's usual in dental practice, to build temporary crowns using self curing acrylics; this way, important amounts of heat are generated during the polimerization process, that may affect the biological preparations. The aim of this research is to know exactly how much heat is generated during polimerazation of some resins and evaluate the relationship between resin volume and temperature rising. This research used self curing resins of three different commercial brands ALIKETM, DURALAY y MARCHE. This brands was used in volumes of: 0.25, 0.5, 1.0 and 1.5 cc. A thermocouple was connected to a digital thermometer to register temperature variations inside the material. Our results showed that the reaction heat is directly proportional to the resin volume used. ALIKE raises the largest temperature for 0.25, 0.5 and 1.0 cc. (40.6, 61.5, and 69.4 oC respectly). For 1.5 cc. DURALAY showed the highest temperature at 86.0 oC. Using ANOVA was found important differences in heat generation between MARCHE and ALIKE only for 0.25 cc group of samples (p=0.001).
