AI Article Synopsis
- A study looked at how strong the roots of teeth from diabetic patients are when under pressure compared to non-diabetic teeth.
- They used different materials to fill the teeth, like white mineral trioxide aggregate (WMTA) and another mixture with an additive, to see which helped make the teeth stronger.
- The results showed that teeth from diabetic patients were more likely to break, but using WMTA or WMTA with an additive made them stronger and less likely to fracture.
Article Abstract
The root fracture resistance (RFR) of premolars extracted from diabetic patients and the effect of biomaterials: white mineral trioxide aggregate (WMTA) and WMTA+Na HPO as an additive, on enhancing RFR were evaluated. Diabetic and non-diabetic teeth were divided into 4 subgroups (n = 5): root canals were obturated with WMTA, WMTA+Na HPO , gutta-percha and one unfilled (control). A plunger (1 mm diameter) applied a downward compressive load with crosshead speed of 1 mm min on the specimens mounted on resin blocks, and the ultimate force to fracture was measured. The mean RFR values of diabetic specimens were significantly lower. The lowest and highest means of RFR were recorded in the control and WMTA, in normal group and the control and WMTA+Na HPO in the diabetic group, respectively. The RFR in diabetic patients was significantly lower, indicating their higher susceptibility to fracture under vertical forces. The use of WMTA (with or without Na HPO ) for obturation enhances the RFR.
