Background & Aims: The DMFT index in primary teeth and dmft in permanent teeth includes drawn (missing) and filled(filling) teeth due to decay and the percentage of children free of caries (caries free) are two important indicators of health in a community. The aim of  this study was to measure the well-being of DMFT  and dmft  indices in Urmia Orphanages .

Materials & Methods: This research was a descriptive-analytical study with 93 patients including 23 females and 70 males. They were  from orphanages  of Urmia with 6-18 years old that were selected  by census method, and their teeth were examined with simple tools.

The results, along with other information such as age, sex, number of brushing and medical data were recorded. The DMFT and dmft indices were based on the method recommended by WHO and the results were analyzed using t-test and k square.

Results: The mean DMFT was 2.55 and dmft was 2.5, respectively and the permanent and deciduous tooth was equal. There was no significant correlation between age and sex and dmft. However, there was significant correlation between age and sex and DMFT. The frequency of brushing and DMFT and dmft meaningful connections was reported.

Conclusion: As a result, the reported decay was higher than  WHO criteria for the year 2010 (DMFT≤1). The highest mean in both DMFT, dmft was related to caries (d,D),respectively. It is revealed that the residents of orphanages need more treatment.
