Abstract

Background  :  Alginat  is  one  of  the  most  used  impression  material  in  dentistry..  Alginate impression need to be disinfected to prevent cross-infection. One of effective natural material that can be used as disinfectant  is avocado  leaves.  The process  of disinfection  could interfered  the dimensional stability of alginate impression caused of imbibition properties in alginate itself. Purpose  : To determine  the differences  of dimensional  stability  of alginate  impression  which disinfected with avocado leave extract 100% compared 0.5% sodium hypochlorite.


Method : This research was an experimental laboratory with post -test only control group design.


Sample were divided into 3 groups, 1 group were sprayed with aquadest as control group and 2 treatment groups were sprayed with avocado leaves extract 100% and 0.5% sodium hypochlorite and stored for 10 minutes. The impression then casted with gypsum in cylinder mold and diameter of the cast were measured. The One Way ANOVA test were used to determine the dimensional stability of the difference between the groups.


Result :The results showed that the alginate impression  which disinfected  with avocado leaves


extract 100% have a significant  dimensional  change, that is 0.123 ± 0.011 mm compared  with 0.5% sodium hypochlorite only 0.034 ± 0.011 mm.


Conclution   :  There  are  differences  in  dimensional   stability  of  alginate  impression   which disinfected with avocado leaf extract 100% and 0.5% sodium hypochlorite.


Keywords:Dimensional stability, avocado leaves extract, and sodium hypochlorite
