  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.
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.
There are many factors affecting polymerization. Since there are insufficient studies on this subject, it should be supported with new research.
