The research instruments were questionnaire and the DMF-T Index examination format. The data were analyzed using the Kendall’s tau-b correlation test. The level of knowledge with the good criteria had a low DMF-T Index of 92.3%, the moderate was as much as 2.6%, and the fair knowledge level had a low DMF-T Index of 5.1%. The Kendall’s tau-b test results showed a relationship between the dental caries knowledge level and the DMF-T Index, and the obtained p value = 0,000 (p < 0.05). The high knowledge level of dental caries affected the results of the DMF-T index.
