COMPARATIVE EVALUATION OF EFFECT OF TWO LIGHT CURING UNITS ON MECHANICAL PROPERTIES OF FILTEK BULK FILL COMPOSITE

Context:The quality of light curing units can profoundly influence mechanical properties dental composite materials. Aim: To compare effect Woodpecker RTA Mini-S and Elipar Deep Cure-L onmechanical (compressive strength, diametral tensile strength microhardness) Filtek Bulk-Fill. Methods Materials: A total 32 samples Bulk Fill were divided into 2 equal groups (n=16). 12 in each group fabricated using a tooth shaped mold 4 circular rings to test compressive microhardness respectively. Theblocks evaluated for the above parameters Universal Testing Machine Vickers Microhardness Tester.Independent sample-t was used this study (p< 0.05). Results: The results showed that composites cured unit better difference between statistically significant (p < 0.05) Conclusion: It concluded higher intensity output conjugation with bulk fill are likely give results.
