Pengaruh casein phosphopeptide amorphous calcium phoshate pada email terhadap shear bond strength resin komposit
L atar Belakang : Penggunaan CPP-ACP secara topikal sering digunakan sebagai produk untuk meningkatkan remineralisasi dan mencegah karies gigi. Aplikasi fluoride topikal pada email menyebabkan perubahan struktur email menjadi lebih tahan terhadap asam sehingga dapat menurukan shear bond strength resin komposit. Tujuan : Untuk melihat pengaruh Casein Phosphopeptide – Amorphous Calcium Phosphate (CPP-ACP) pada email terhadap shear bond strength resin komposit. Metode Penelitian : Sebanyak 10 sampel gigi premolar pasca ekstraksi dibagi menjadi 2 kelompok, yaitu kelompok perlakuan yang direndam CPP-ACP tooth mousse selama 3 menit pada bagian mahkota gigi kemudian ditunggu 30 menit dan kelompok kontrol yang direndam menggunakan saliva buatan. Kedua kelompok diberi perlakuan berulang selama 7 hari dan disimpan dalam inkubator dengan suhu 37° Celsius. Pada hari kedelapan, seluruh sampel ditempel dengan resin komposit dan dilakukan pengujian kekuatan geser perlekatan (shear bond strength) menggunakan Universal Testing Machine dengan kapasitas beban maksimum 5kN dan kecepatan 0.5 mm/menit. Data dianalisis dengan uji normalitas Shapiro Wilk dan Uji One-Way ANOVA. Hasil : Uji normalitas Shapiro Wilk menunjukan data berdistribusi normal (p<0.05). Uji One-Way ANOVA menunjukan tidak terdapat pengaruh signifikan pemberian CPP-ACP pada email terhadap shear bond strength resin komposit. Kesimpulan : Pemberian CPP-ACP pada email tidak mempengaruhi shear bond strength resin komposit.
B ackground : The use of CPP-ACP topically is often used as a product to increase remineralization and prevent dental caries. The application of topical fluoride to enamel causes changes in the enamel structure to become more resistant to acids, thereby reducing the shear bond strength of the composite resin. Purpose : To see the effect of Casein Phosphopeptide – Amorphous Calcium Phosphate (CPP-ACP) on enamel on the shear bond strength of composite resins. Methods: A total of 10 samples of post-extraction premolars were divided into 2 groups, namely the treatment group which was soaked in CPP-ACP tooth mousse for 3 minutes on the crown of the tooth and then waited 30 minutes and the control group which was soaked using artificial saliva. Both groups were given repeated treatments for 7 days and stored in an incubator at 37° Celsius. On the eighth day, all samples were affixed with composite resin and tested for shear bond strength using a Universal Testing Machine with a maximum load capacity of 5kN and a speed of 0.5mm/min. Data were analyzed using the Shapiro Wilk normality test and the One-Way ANOVA test. Results: The Shapiro Wilk normality test showed that the data were normally distributed (p<0.05). The One-Way ANOVA test showed that there was no significant effect of adding CPP-ACP to enamel on the shear bond strength of the composite resin. Conclusion: Giving CPP-ACP to enamel does not affect the shear bond strength of the composite resin.
