Abstract—The dental chair unit is used by many patients during dental treatment every day, so dental unit waterlines (DCWs) should be disinfected. DCWs often use disinfecting cartridges containing iodine. The aim of this study was to measure iodine concentration and to evaluate its antimicrobial effect. Distilled water flowed through the iodine release cartridge, and iodine concentration of the water pumped through the cartridge was collected and measured every day for 5 days. The antibacterial effect was evaluated by Quantitative PCR and PMA dye PCR method. The iodine concentration was 1.1 ppm at the collection time and started to decrease after two days. After 5 days the concentration was reduced to 0.4 ppm. The iodine water showed an antibacterial effect 12 h after application. The iodine-release DCW disinfectant product killed 99.99 % of the bacteria within 48 h, and the concentration of iodine was lower than that mentioned the drinking water guideline recommended by the WHO.
