Abstract

Objective To develop zinc oxide calcium sulfate based temporary filling material with less disintegration in water. Materials and methods Four formulas of temporary filling materials were prepared by altering the ratio of calcium sulfate and zinc oxide. Cavit was used as a control group. Twenty specimens from each group were tested to find the mean percentage of disintegration in each group. One-way ANOVA and Bonferroni multiple comparison were used to analyze data. Results The mean percentages of disintegration of the newly developed temporary filling materials were 8.884 ± 0.789, 4.930 ± 1.157, 3.629 ± 1.039 and 10.594 ± 1.097 in specimens of formula 1, formula 2, formula 3 and formula 4, whereas Cavit was 13.455 ± 1.185. All groups of newly developed temporary filling materials were significantly different between groups and significantly lower than Cavit (p < 0.05). Conclusion The newly developed temporary filling materials from four formulas were significantly less disintegrated than Cavit.
