Background
DMFT index is the most common caries detecting index worldwide. The aim of present study was to determine DMFT as well as the prevalence of highest caries rate or Significant Caries Index (SiC), among 15 years of age female students in the city of Rasht, Iran.
Materials and methods
In this descriptive cross-sectional study, 228 female students were selected using stratified multi-stage sampling method. Demographic status was assessed by questionnaire. Clinical examinations were conducted by a trained senior dental student. DMFT index was  firstly determined by WHO criteria. At the next stage, SiC index was extracted by calculating DMFT among one third of study population who had the highest rate of DMFT. Analyzed by SPSS 21. Spearman correlation, Kruskal Wallis و Chi-square T-test,Data were used for data analysis.
Results
The mean DMFT was 3.29±2.7, and SiC index was 6.19±0.76. Spearman correlation determined that there was a positive direct correlation between DMFT and the number of children within the family (P<0.0001). A negative correlation was observed between DMFT and daily tooth brushing(P<0.0001).
Conclusion
The mean DMFT index among 15 years-old females was similar to mean national scores. The number of siblings and tooth brushing were correlated with DMFT score in the study population.
