One of the herbal plants that can be used as an alternative material as a disclosing solution is Rosella (Hibiscus sabdariffa L.) which can be used for its properties in the field of Prevention of Dental and Oral Diseases and has antibacterial and remineralizing effects. Methods: This research is an experimental study on the development of Rosella Flower Extract (Hibiscus sabdariffa L.) in the form of a gel in disclosing solution. The research was carried out from June to August 2021 at the Pharmacognosy Laboratory, Department of Pharmacy and Food Analysis, Health Polytechnic of Jakarta II and Dental Health Laboratory, Health Polytechnic of Jakarta I. Disclosing solution prepared from dried Rosella Flowers (Hibiscus sabdariffa L.) was obtained as much as 1000 grams. from the Research Institute for Spices and Medicinal Plants, Bogor.

Results: The disclosing solution preparation in the form of a gel from rosella flower extract had good organoleptic test results. The expected red color corresponding to the color of the disclosing solution is at a concentration of 70%. The average pH of the disclosing solution in the form of a gel was 4.95. The average dispersion of the gel preparation is 5.7. 5. The average adhesion of gel preparations at all concentrations is 1.44 seconds. The hedonic test was obtained that most of the respondents had a neutral opinion on all disclosing gel preparations.
