Abstract

The aim of the study was to investigate the possible influence of disinfectant (sodium hypochlorite solution) upon the horizontal and vertical dimensions of gypsum casts produced by pouring of irreversible hydrocolloid impressions desinfected by immersion in the desinfectant. For the realization of this study, 30 irreversible hydrocolloid impressions impressions were divided in three groups: G1 - immersed in water, G2 - immersed in sodium hypochlorite disinfectant for 15 minutes, G3 - immersed in a sodium hypochlorite disinfectant for 30 minutes. Every impression was poured with gypsum IV class and measurements were made between precisely defined points of the central maxillar incisors and the left and right maxillar first molar. The obtained values were statistically analyzed using, Kruskal - Wallis ANOVA test, Mann - Whitney test, t - test for independent samples, analysis of variances, Post hoc analysis Tukey HSD test. Based on the performed measurements, as well as the statistical analysis and evaluation, 15 and 30 minutes' immersion in disinfectant is an acceptable irreversible hydrocolloid impression disinfection method, without producing significant dimensional changes of poured gypsum cast.
