The present study was conducted to investigate the demographic characteristics and DMFT Index in adults referred to Yazd Dental School in Yazd, Iran in 2021.

In this descriptive cross-sectional study, 500 adult patients in the age group of 18 to 65 years were studied. 343 (68.6%) of the samples were female and 157 (31.4%) were male. The patients completed a questionnaire, including their demographic characteristics and socio-economic status. DMFT index was also recorded in the study questionnaire. Data were analyzed by SPSS17 statistical software and Mann-Whitney, Kruskal-Wallis and Tukey statistical tests.

The mean total DMFT index was 9.7± 5.1. There was a statistically significant difference in the mean DMFT index by age (P = 0.017), level of education (P = 0.000), occupation (P = 0.001) and number of family members ( P= 0.007), however, no statistically significant difference was observed in the mean DMFT index according to gender, place of residence, and monthly income of participants (P <0.05).

The mean DMFT index is influenced by demographic characteristics. Older age, more family members, higher education level and better position jobs had the greatest impact on the mean DMFT index.
