Matearils and Methods

The study is a comparative study. The sample size for this study was 160 cases  including all children and adolescents aged 9-18 years, 80 patients with type 1 diabetes (case group) and 80 healthy cases (control group) who were similar in age and sex. A written consent and a researcher-made questionnaire were completed by the two groups. The analysis was performed using chi-square, independent t-test, and correlation coefficient in SPSS 22 and Graphpad Prism8 software.


The mean age of the subjects was 13.4±3 in the diabetic group and 12.8±2.9 years in the healthy group. There was no statistically significant difference between the two groups (P> 0.05). The number of DMFT teeth in children with type 1 diabetes was significantly higher than healthy children (P <0.05). There was a significant relationship between the number of decayed teeth and HbA1c (r = 0.3, P = 0.004). Also, there is a direct and statistically significant relationship between DMFT and HbA1c (r = 0.36, P = 0.001).


In this study (DMFT) was higher in the diabetic group than in the healthy group. A direct correlation was also  seen between HBA1C and (DMFT).
