PERBEDAAN STABILITAS DIMENSI ANTARA CETAKAN ALGINAT YANG DIBERI DESINFEKTAN EKSTRAK DAUN ALPUKAT (Persea americana mill) DENGAN NATRIUM HIPOKLORIT

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

Effect of alginate impression disinfection with sodium hypochlorite and castrol oil on Candida albicans counts and dimensional stability of the study model

“…29 This study was also in accordance with the study of Amelia, et al which showed there was a change in dimensional stability which was still within the tolerance limits of alginate impression after 0.5% sodium hypochlorite was sprayed. 9 Disinfection of alginate impression with 10% castor oil in group C2 showed an effect on the dimensional stability of the study model. The results of this study were in accordance with previous study by Hasanah, et al concluded that disinfection of alginate impression by spraying 80% betel leaf solution resulted in insignificant changes in dimensional stability.…”

“…The esterification reaction would produce esters and H2O, while alginate had properties that were easy to imbibe causing the increase of the disinfectant solution absorption and affecting the dimensional stability of the study model. 9,24,25 Group B1 showed the greatest decrease in the amount of C.albicans caused by the disinfectant effect of sodium hypochlorite where the chlorine content of the released sodium hypochlorite adheres to the cell cytoplasm which could destroy important C.albicans proteins. The results of this study were in accordance with the research of Bustos, et al in their research explaining that 0.5% so-dium hypochlorite could reduce the amount of bacteria including C.albicans in alginate impression.…”

“…According to the American National Standards Institute/American Dental Association (ANSI/ADA) specification No.18 changes in dimensions that occur in impression material less than 0,5%. 9 Chemical disinfections were recommended by ADA guidelines because they are virusids, bactericids, and sporosids. Disinfecting materials that were often used to disinfect impression material were divided into two types, namely non-traditional and traditional chemicals.…”

Pengaruh Penyemprotan Larutan Ekstrak Daun Salam 12,5% Pada Cetakan Alginat Terhadap Stabilitas Dimensi

“…Penelitian yang dilakukan oleh nisa dkk menyatakan bahwa teknik penyemprotan lebih menguntungkan di lakukan, karena teknik ini dapat mengurangi terpaparnya cetakan alginat terhadap larutan desinfektan, alasan tersebut merupakan mengapa tidak terhjadi perubahan stabilitas dimensi alginat setelah dilakukan desinfeksi dengan larutan daun sirih 80%.

Pengaruh Variasi Waktu Perendaman dalam Ekstrak Daun Teh Hijau (Camellia sinensis) terhadap Stabilitas Dimensi Alginat

“…Alginat memiliki sifat yang mudah mengalami imbibisi sehingga bila ekstrak daun teh hijau yang mengandung senyawa fenol berkontak dengan alginat dapat menyebabkan ekspansi hasil cetakan. 15 Pada penelitian ini dilakukan pengukuran dimensi anteroposterior dan mediolateral untuk memastikan akurasi stabilitas dimensi alginat setelah dilakukan desinfeksi agar tidak memengaruhi rencana perawatan selanjutnya. 16…”
