Abstract

Treatment with fixed orthodontic appliances can pose various risks, especially increasing plaque accumulation. Green tea (Ca-mellia sinensis) which is one of the natural alternatives that can be used to inhibit dental plaque formation, contains catechins, flavonoids and tannins as antibacterial Streptococcus mutans which is the agent of dental plaque formation. This article discus-ses the difference in orthodontic plaque index (OPI) scores before and after rinsing with green tea brewing (GTB) in fixed ortho-dontic users. Experimental research with a one-group pretest-posttest design using research subjects namely preclinical stu-dents of Baiturrahmah University Faculty of Dentistry class 2022 and 2023 who used fixed orthodontics according to the inclu-sion criteria totalling 40 people. Data collection according to the examination of OPI score before and after gargling with GTB. Data analysis showed a significance value of p=0.000 (p<0.05) which indicated that there was a difference in OPI scores be-fore and after gargling, which decreased from 41.75% to 23.94%. It was concluded that gargling with GTB can reduce the OPI score of fixed orthodontic users.

Abstract

Candidiasis is a fungal infection caused by overgrowth of Candida albicans species. Noni fruit (Morinda citrifolia L.) is one of the plants that has antifungal activity through the content of compounds such as flavonoids, saponins, alkaloids, terpenoids, pheno-lics, and tannins. This study discusses the inhibition of noni fruit extract (NFE) at concentrations of 10%, 15%, and 20% against the growth of C.albicans using laboratory experimental methods with a descriptive approach and using a one shot case study de-sign. Noni fruit was extracted using maceration method with 96% methanol solvent. A total of 18 samples of C.albicans were divi-ded into 3 treatments, namely 10%, 15% and 20% concentrations. The inhibition test was carried out using the pitting diffusion me-thod, while the measurement of the inhibition zone using a caliper showed that 10% NFE had an inhibition that was categorised as moderate, 15% was categorised as strong, and 20% was also categorised as strong. It was concluded that noni fruit extract has inhibitory power against the growth of C.albicans, with the best effectiveness at a concentration of 20% which showed a strong inhibition category.
