Abstract

Flowable composite has lower filler content (37%-53%) compared to packable composite. Lower filler content can reduce compressive strength. Compressive strength is an important mechanical property that needs to be tested because most masticatory force is compressive strength. Flowable composite has been developed to achieve better mechanical and aesthetic properties. Various types of fillers have been developed, one of which is adding fluoride. Fluoride addition has been proven to prevent secondary caries, however its effect on the compressive strength of flowable composite still requires further research. To compare the compressive strength of conventional flowable composite and fluoride-based flowable composite.This study is a laboratory experimental study with posttest-only control group design. Samples were moulded using a stainless-steel split mold with 3 mm diameter and 6 mm thickness. Twenty samples were divided into two groups, conventional flowable composite group and fluoride-based flowable composite group. The samples were filled using the incremental technique and light cured with intensity 1400 mW/cm2 LED for 10 second. Samples were finished using composite polishing disc and compressive strength was tested with a universal testing machine. Data analysis using Shapiro-Wilk test, Levene's Test of Variance, and Independent T-Test. The average value of compressive strength conventional flowable composite is 373.14 MPa and fluoride-based flowable composite is 280.20 MPa. Analysis of the data obtained using Independent T-Test (p<0,05) showed there was a significant difference between the two group. There is a significant different between compressive strength of conventional flowable composite and fluoride-based flowable composite.
