Tindakan bleaching dan perawatan ortodonti sering dijadikan langkah awal dalam usaha memperbaiki penampilan. Tindakan in-office bleaching dapat menyebabkan sensitivitas gigi meningkat sehingga digunakan desensitizing agent. Tindakan in-office bleaching dan desensitizing agent berbasis fluor atau non-fluor akan memengaruhi morfologi permukaan email gigi. Perubahan morfologi tersebut berpotensi memengaruhi kekuatan geser dan ikatan bracket pada perawatan ortodonti. Penelitian ini bertujuan menganalisis pengaruh desensitizing agent fluor dan non-fluor pasca in-office bleaching terhadap kekuatan geser bracket logam dengan sementasi resin komposit.

Dua puluh tujuh gigi premolar pasca pencabutan dibagi menjadi 3 kelompok: kelompok kontrol, kelompok desensitizing agent fluor, dan kelompok desensitizing agent non-fluor. Prosedur bonding bracket dilakukan pada ketiga kelompok kemudian dilanjutkan dengan uji kekuatan geser menggunakan universal testing machine dengan kecepatan 1 mm/menit. Analisis skor ARI dilakukan setelah uji kekuatan geser. Data hasil penelitian uji kekuatan geser dianalisis menggunakan one way ANOVA dilanjutkan uji Post Hoc Tukey. Data analisis skor ARI dianalisis menggunakan Kruskal-Wallis dan uji Mann-Whitney. Seluruh data dianalisis dengan tingkat kepercayaan 95%.

Hasil analisis statistik menunjukkan terjadi peningkatan kekuatan geser secara signifikan (p<0>desensitizing agent fluor dibandingkan kelompok desensitizing agent non-fluor dan kelompok kontrol. Rerata kekuatan geser tertinggi terdapat pada kelompok desensitizing agent fluor. Analisis skor ARI menunjukkan terdapat perbedaan antara kelompok desensitizing agent fluor dengan kelompok desensitizing agent non-fluor dan kontrol. Kesimpulan penelitian ini adalah desensitizing agent fluor pasca in-office bleaching meningkatkan kekuatan geser dan bahan adhesive lebih banyak tertinggal di permukaan gigi dibandingkan desensitizing agent non-fluor pasca in-office bleaching pada bracket logam dengan sementasi resin komposit.

Bleaching and orthodontic treatment are often used as the first steps to improving a person's appearance. One of the adverse effects of in-office bleaching is tooth hypersensitivity, which could be neutralized with a desensitizing agent. In-office bleaching and the application of desensitizing agents will affect the morphology of the enamel surface. These morphological changes have a potential effect on shear bond strength (SBS) and bonding brackets in orthodontic treatment. This study aims to analyze the effect of fluoride and non-fluoride desensitizing agents post-in-office bleaching on the SBS of metal brackets with resin composite cementation.

Twenty-seven post-extraction premolars were divided into 3 groups: control, fluoride desensitizing agent, and non-fluoride desensitizing agent group. The bonding bracket procedure was performed on the three groups, followed by the SBS test using a universal testing machine. ARI score analysis was carried out after the shear bond strength test. The data from SBS were analyzed using one-way ANOVA followed by a post hoc Tukey test with a 5% significance level. The data for ARI score analysis were analyzed using the Kruskal-Wallis test followed by the Mann-Whitney test with a 5% significance level.

The results showed that shear bond strength increased significantly in the fluoride desensitizing agent group compared to the non-fluoride desensitizing agent group and the control group (p< 0>
