Ekstrak Kubis Ungu (Brassica oleracea L.) sebagai Alternatif Disclosing Agent untuk Identifikasi Dental Plaque

Abstract

Periodontal disease is a disease that causes tooth loss due to bacterial inflammation which causes progressive damage to the supporting tissues of the teeth. One of the causes of periodontal disease is due to the buildup of plaque. Dental plaque in the oral cavity has a transparent and thin layer so that it is often to be invisible, but dental plaque can be seen if it is given a coloring such as a disclosing agent. The disclosing agent that is commonly used today is erythrosine, but erythrosine is not recommended for its use because it has toxic properties that can cause thyroid cancer. It is known that disclosing agent can be made using natural ingredients which contain anthocyanin substances and one of the natural anthocyanin dyes that has the potential to be used as a disclosing agent is purple cabbage (Brassica oleraceae L.). The purpose of this study was to determine whether purple cabbage extract could be used as an alternative disclosing agent. This research is a quasi-experimental study with a posttest only one group design and in vivo observations with a total sample of 16 students from Faculty of Dentistry University of North Sumatra class of 2019 who meet the inclusion and exclusion criteria. The clinical examination was carried out at 12.00 with two treatment groups of erythrosine disclosing agent and purple cabbage extract, then the plaque control record score was measured using the O'Leary method. The results showed that the average plaque score using disclosing agent was 65.984% and using purple cabbage extract was lower by 56.428%. The results of the Shapiro Wilk normality test revealed that erythrosine disclosing agent and purple cabbage extract treatment groups were normally distributed with p values of 0.130 and 0.406 respectively (p>0.05), so the parametric test to be used was the independent sample test. The parametric test results interpreted the p-value to be 0.154 (p>0.05), which means that in this study there was no significant difference regarding the difference in plaque scores between the disclosing agent erythrosine and purple cabbage extract.
