The clinical significance of increasing the depth of cure of posterior composites in the cervical region of a class 11 cavity has lead to the introduction of light transmitting wedges, matrices and cones. This study was conducted to evaluate the efficiency of existing transparent wedges and an innovative fibre optic cable. Simulate class IIcavities were prepared in brass blocks and restored with four popular posterior composite resins having an uniform vita shade. With the standardized curing time of 60s, the materials were polymerized by three different techniques (1) Conventionalmethod (2) Using fibre optic cables (3) Using light transmitting wedges. The specimens were subjected to vickers hardness test using shimadzu microharness meter after 1 hour and 24 hours. The results were tabulated and evaluated for any statistically significant variation in the depth of cure. |
