Pengaruh Rebusan Daun Salam (Eugenia polyantha Wight) 100% dan Sodium Hipoklorit (NaOCl) 1%terhadap Stabilitas Dimensi Hasil Cetakan Hidrokoloid Ireversibel (The Effect ofBay Leaf (Eugenia polyantha Wight) Boiling Water 100% and Sodium Hypochlorite (NaOCl) 1% to Dimensional Stability of Irreversible Hydrocolloid Impressing Produce)

Abstract

Background: A factor that should be considered in the use of irreversible hydrocolloid impression materials or alginate is cross-infection control, therefore the result of alginate impressing produce should be disinfected using a chemical or natural materials, such as sodium hypochlorite (NaOCl) 1%, and bay leaf boiling water 100% before gypsum filling, but that procces can cause dimensional changes. Objective: The objective of this research is to determine the effect of the use of these materials with flushing and immersing method for dimensional stability of alginate impressing produce. Method: The type of this study is a laboratory experimental with post test only control group design. Total sample is 24 samples of alginate impressing produce were devided in to 6 groups: 2 control groups and 4 treatment groups using the flushing and immersing methods. Data were tabulated and analyzed with One Way Analiysis of variance (Anova) technique adjusted for multiple comparisons using LSD method was used for immersing method. Result and Conclusion: The result of the study shows that there is dimensional changes of the group by immersing method, but use flushing method do not have a significant effect on dimensional changes of alginate impressing produce.
