  Objective: To use AutoCAD software to examine the microleakage of bulk-fill composites occurring as a result of polymerization with different light sources.
Study Design:
In a total of 40 extracted first molar teeth, class I cavities were opened. Then 4 groups were formed of 10 samples in each group. All the samples were restored with SDR bulk-fill composite. The samples were polymerized with an LED light source as follows: Group 1, Mikado; Group 2, Woodpecker; Group 3, Planmeca; and Group 4, CarboLED. Each tooth was divided into 2 sections. Each section was examined under stereomicroscope, and the dimensions of the leakage surface area were measured with AutoCAD software. In the statistical evaluations of the data, the Kruskal-Wallis and Tukey B tests were used.
Results:
Significant differences were found between the groups in the statistical evaluations (p<0.05). The highest value was found in the CarboLED group and the lowest value was found in the group where Mikado light source was used.
Conclusion:
There are many factors affecting polymerization. Since there are insufficient studies on this subject, it should be supported with new research.
