MEDEIROS, João Marcelo Ferreira de et al. Reliability of ice and refrigerant gas before and after in restorative procedures. Rev. Assoc. Paul. Cir. Dent. [online]. 2012, vol.66, n.3, pp. 200-205. ISSN 0004-5276.

The aim of this study was to compare the frequency of positive and negative responses and intensity of patient pain in the thermal application in 625 human caries teeth before and after the restorative procedures. Pain intensity was measured by Visual Analogue Scale represented by a calibrated rule 1-10 mm. Before making the restoration was applied the ice stick and then the refrigerant gas to obtain the pulp response. After the restoration were made the new application testing and evaluation of pain intensity availing himself of that scale. The data before and after the restorative procedures were tabulated by analyzing the frequency and percentage of positive and negative responses and pain intensity as mild, moderate and intense. By comparing the ice stick and refrigerant occurred percentage difference of positive and negative responses with statistical significance (p = 0.00001) occurring at the same intensity of pain at its three levels both before and after restorative procedures. it concluded that the refrigerant compared to the ice stick determined more positive response frequencies both before and after restoratives procedures. The number of teeth with pain before the restorative procedures was higher than after application of the restoration of ice stick as the refrigerant.As a moderate and mild pain intensity was found that before performing the restoration percentage rates were lower in relation to pain intensity after the restorative procedures both the application of ice and the refrigerant gas.
