| Summary: | The irrigation of root canal is an important step to support the success of
root canal treatment due irrigation facilitates necrotic tissue, microorganisms and
residual dentin disposal of infected root canals. Irrigation solution used in
endodontic therapy is sodium hypochlorite and Chlorhexidine. The irrigation
materials may produce chemical changes and physical properties of dentine. The
purpose of this study was to determine the effect of a combination of 2.5% NaOCl
irrigation solution and 2% chlorhexidine to the root canal micro dentine
hardness.
This study uses 10 single root premolars cut in the cemento enamel
junction (CEJ). The teeth roots that have been prepared in a vertical cut into the
medial and distal then planted in acrylic resin blocks. Twenty pieces of teeth were
divided into 4 groups, group I was applied NaOCl 2.5%, group II was applied
Chlorhexidine 2%, group III was applied combination of 2.5% NaOCl and 2%
chlorhexidine, group IV was applied Saline as a control group. Before treatment,
initial value of micro hardness tester with Vickers micro hardness was
calculated. Once applied irrigation solution for 20 minutes, the micro hardness
value measured. Changes in the micro hardness value data were analyzed with
Kruskall Wallis test and Mann-Whitney U test.
The results show there are significant changes to the type of irrigation
solution root canal dentin micro hardness. The conclusions are all kinds of
irrigation solution causes a decrease in micro hardness values, where the
combination of NaOCl solution 2.5% and 2% Chlorhexidine causes a decrease in
the highest micro hardness when compared to other groups. |
