| dc.description.abstract | The release of nickel ions in orthodontic brackets can cause hypersensitivity reactions.
The gold standard mouthwash is chlorhexidine, but it has the side effect of disrupting
the balance of normal flora in the oral cavity. So another alternative is needed, namely
herbal mouthwash. One herbal mouthwash is activated charcoal from palm oil shells.
Activated charcoal suspension has antibacterial properties which can reduce the
number of bacterial colonies, so that plaque accumulation is reduced and saliva pH
can increase. The aim of this study was to determine the difference in the average
release of nickel ions in stainless steel orthodontic brackets after immersing activated
charcoal suspension from palm oil shells for 7 and 14 days using ICP-OES. This
research is a laboratory experimental research. The research samples were 30 samples
of Ormco brand mini diamond type stainless steel orthodontic brackets for premolars
and divided into 6 groups. Based on research, it can be concluded that the average
release of nickel ions respectively after soaking in artificial saliva, chlorhexidine 0,2%,
and 12% activated charcoal suspension from palm oil shells for 7 days is
(0,0027±0,0003; 0,0149±0,0013; 0,0017±0,0002) ppm and for 14 days
(0,0034±0,0019; 0,0179±0,0073; 0,0017±0,0004) ppm; and there is a difference in the
average amount of nickel ion released from Ormco brand stainless steel premolar
orthodontic brackets after soaking for 7 days and 14 days. | en_US |
