Oral problems                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            are one of the most health problems in these patients. The present study was designed and accomplished by the aim of determining the status of DMFT index in type II diabetic patents and its correlation with HbAc1 in Yazd city in 2013.

Methods: In this descriptive-sectional study, 203 type II diabetic patients who referred to the center of diabetes research in Yazd, were selected and studied in two groups of controlled and un-controlled (HbA1c under and over <7%)  by the single-randomized method. The required data and also demographic information were collected by a questionnaire which consisted of DMFT index and HbAc1.The data were analyzed by SPSS ver.17 and Chi-square test, Fisher's exact test, ANOVA, T-test and correlation coefficient.

Results: Our findings showed that the average number of decayed, missed and restored teeth were significantly higher in patients with un-controlled diabetes (P =0.000). Also Perarson's correlation coefficient showed a significantly positive relationship between HbAc1 and age, duration of having diabetes, decayed tooth, ,missed tooth and restored tooth. There was a statically significant difference for DMFT in two groups according to using toothbrush and Dental floss (P =0.000).

Conclusion: The mean score of DMFT in patients with un-controlled diabete was significantly more than patients with controlled diabetes. Also HbAc1 had a significant and positive relationship with age, duration of having diabetes, decayed tooth, missed tooth, restored tooth and oral health (using toothbrush and dental floss).
