ABSTRAK
Penelitian bertujuan mengetahui pengaruh besar tekanan dan lama scrubbingterhadap kuat rekat geser self adhering flowable composite pada dentin. Selfadhering flowable composite diaplikasikan dengan tekanan scrubbing 1, 2, dan 3gram masing-masing selama 15, 20, dan 25 detik. Resin komposit diaplikasikansecara inkremental. Polimerisasi dengan sinar selama 20 detik. Kuat rekat geserdiuji menggunakan Testing Machine dan dianalisa dengan ANOVA diikuti PostHoc Test Bonferroni. Daerah patahan diobservasi menggunakan SEM. Kuat rekatgeser tertinggi pada tekanan scrubbing 3 gram selama 25 detik. Perbedaan besartekanan dan waktu saat scrubbing mempengaruhi kuat rekat geser self adheringflowable composite pada dentin.

Abstract

Effect of different scrubbing pressure and duration on shear bond strength of self

adhering flowable composite to dentin was evaluated. Self adhering flowable

composite was applied on dentin with 1, 2, and 3 grams pressure for 15, 20, and

25 seconds. Composite was constructed incrementally. Polymerization for 20

seconds. Shear bond strength was tested with a Testing Machine and analyzed by

ANOVA and Bonferroni. Fractured area was observed with a SEM. The highest

shear bond strength was obtained in 3 grams scrubbing pressure for 25 seconds.

The different scrubbing pressure and duration influenced shear bond strength of

self adhering flowable composite to dentin.
