Findings

The comparison of the thickness of the cementum layer between the groups revealed the following: (Table 1)

1. A statistically significant difference with regard to the thickness of the apical cementum layer between Type 2 diabetic and non-diabetic subjects (p < 0.05) (t = -4.994).
2. A statistically significant difference with regard to the thickness of the cementum layer in the apical half of the root between Type 2 diabetic and non-diabetic subjects (p < 0.05) (t = -5.969).
3. A statistically significant difference with regard to the thickness of the cementum layer in the central point of the root between Type 2 diabetic and non-diabetic subjects (p < 0.05) (t=4.044).
4. A statistically significant difference with regard to the thickness of the cementum layer in the cervical half of the root between Type 2 diabetic and non-diabetic subjects (p < 0.05) (t=5.132).
