The sample included 100 Iraqi dental students and 90 Yemeni dental students of fourth grade, age ranged between 22–23 years old of both sexes. The study revealed that there was a significant difference in the DMFT between Iraqi and Yemeni dental students for the total sample at p < 0.05 level, with significant difference between Iraqi and Yemeni dental students for both sexes at p < 0.01 level. The results also revealed that there was no significant difference in the type of treatment required for the total sample between females of Iraqi and Yemeni dental students, but with significant difference in the treatment need between males of Iraqi and Yemeni dental students. Highest percentage of treatment need for Iraqi and Yemeni students were for 1 surface restoration.
