Background Decayed, Missing, and Filled Teeth (DMFT) indicator is one of the most epidemiologic indexes in dentistry indicating the situation of oral and dental health among people of a society. The present study has been conducted with the aim of determining the dmft index among Iranian first-grade elementary students. Materials and Methods This study was conducted on 3,000 (1,500 girls and 1,500 boys), first-grade elementary students in Mazandaran province through descriptive-analytical method. Sample members were gathered using random sampling method. Participants were checked sitting at a conventional seat on the natural light using disposable mirror and dental explorer by a senior dental student. Results The total dmft of students was 4.08 ± 2.93 at which there were no significant differences between the dmft of boys and girls. dmft of students in urban areas was 3.94 ± 3 and in rural areas the dmft of students was 4.43 ± 2.66 that the statistical difference between these two groups was significant (P=0.032). dmft difference between healthy people and those with systemic disease was not significant (P=0.818). Conclusion The results of this study showed that dental health status of first-grade students in Mazandaran province needs more attention in order to get closer to the international standards in this regard.
