Abstract (Abstrak)

Background: Dental moulds must be disinfected to prevent cross-contamination,
especially in infectious disease situations such as COVID-19. For this purpose, the
American Dental Association (ADA) recommends disinfecting dental moulds by rinsing
them with water, and then immersing them in a disinfectant solution such as 0.5% sodium
hypochlorite for a standard time of 10 minutes. Although chemical disinfectants such as
sodium hypochlorite are effective, their use may cause side effects. As a natural alternative,
green tea leaf extract (Camellia sinensis), which is known to have antimicrobial and
antioxidant properties, offers a safer and eco-friendly option without compromising on
mould accuracy. Research Objective: To assess the impact of spraying and soaking
disinfection techniques with 50% green tea (Camellia sinensis) leaf extract on the
dimensional stability of alginate. Research Methods: Laboratory experimental research
with a research sample of 28 alginate moulds given three different treatments namely
spraying, soaking and no treatment. The data analysis used was one way anova test and
duncan test. Research Results: Both disinfection techniques were effective in preventing
cross-contamination, but spraying resulted in smaller dimensional changes than soaking,
although both remained within clinical tolerance limits according to ADA No. 19. Green tea
leaf extract may be an effective alternative to natural disinfectants. Conclusion: Theuse
of 50% green tea (Camellia sinensis) leaf extract as a disinfectant affects the dimensional
stability of alginate moulds. The spraying technique resulted in smaller dimensional
changes compared to immersion, although both remained within clinical tolerance limits
