DIAGNO dent® is a caries detector using semiconductor laser. The newly-developed DIAGNO dent® pen - Perio Probe is capable of examining the accumulation of materials such as dental plaque or calculus in the periodontal pocket. However, it is possible that the dye within the plaque tester may affect the measurement value of caries. In this study, we examined how the measurements were affected by the plaque tester. As a result, the plaque tester containing Coomassie Brilliant Blue showed a higher measurement value. This result suggests that when using a plaque tester containing Coomassie Brilliant Blue, the DIAGNO dent® pen - Perio Probe may not be able to accurately evaluate the accumulation within the periodontal pocket.
