Latar Belakang: Penelitian terakhir melaporkan bahwa kombinasi teknik self ecth dengan penambangan etsa dapat meningkatkan ikatan bahan adhesif pada sementasi fiber post. Namun masih perlu dievaluasi efek ikatan bahan adhesif teknik kombinasi penambahan etsa ini. Tujuan: Penelitian ini bertujuan untuk mengetahui perbedaan penetrasi semen resin ke dalam tubulus dentin pada sementasi fiber post antara teknik etsa dan kombinasi. Metode: tiga puluh dua gigi premolar paska perawatan saluran akar telah dipreparasi preparasi ruang pasak sepanjang 10 mm. Kelompok penelitian pertama menggunakan sistem adhesif self etch, kelompok kedua kombinasi penambahan etsa. Pasak fiber disemen menggunakan semen resin dengan pewarnaan fluorescence rhodamine B 0.1%. Gigi dipotong 2 mm sepertiga tengah akar. Sampel dianalisis dengan confocal laser scanning microscopy. Uji statistik menggunakan uji T Independent dan uji korelasi Pearson. Hasil: Terdapat perbedaan nilai densitas ikatan hibrida dan kedalaman penetrasi resin tags. Nilai densitas ikatan hibrida pada kelompok penelitian kedua lebih tinggi dibanding kelompok pertama dan berbeda bermakna secara statistik. Terdapat korelasi linear posisif kuat yang bermakna secara statistik antara densitas ikatan hibrida dan kedalaman penetrasi resin tags pada kedua kelompok. Kesimpulan: Densitas ikatan hibrida dan kedalaman penetrasi resin tags pada teknik kombinasi penambahan etsa memiliki nilai yang lebih tinggi dibandingkan dengan teknik self etch. Semakin tebal densitas ikatan hibrida maka semakin panjang kedalaman penetrasi resin tags, sehingga meningkatkan kekuatan mekanis semen resin terhadap subsrat gigi. ......Background: Recently, combination of self-etch and additional etch technique as pre cementation procedures of fiber post restoration was reported to be the best. Although this combination still need to be investigated due to the binding effect between adhesive material and dentine. Objective: To determine the effects of different etching techniques on resin cement penetration into dentinal tubules. Methods: Thirty-two endodontic treated premolars were prepared for 10 mm fibre post. The samples were divided into two research groups, first group was treated with, self-etch only then the second one was treated with combination of self-etch and additional etching. Fibre post cemented using fluorescence rhodamine B 0.1% colored resin cement. Teeth were cut with 2 mm thickness in the middle third of root. The samples were analyzed with confocal laser scanning microscopy. Statistical analysis measurement was evaluated by Independent T test and Pearson correlation test. Result: Different hybrid layer density and penetration length of resin tags between two groups were detected. Statistically different and higher hybrid layer density score on self-etch with additional etching group were identified. Statistically strong linear positive correlation between hybrid layer density and penetration length of resin tags in both groups were also noticed. Conclusion: Hybrid layer density and penetration length of resin tags on self-etch with additional etching showed higher scores. The thicker the hybrid layer density, the longer penetration of resin tags, this phenomenon may increase mechanical strength regarding stronger bind of resin cement to tooth substrate.

Latar belakang: Restorasi estetik Porcelain laminate veneer PLV menggunakan semen resin sebagai bahan adhesif pada permukaan gigi. Salah satu faktor keberhasilannya adalah kesesuaian warna PLV dengan gigi yang ada, dimana semen menjadi faktor yang mempengaruhi. Kontroversi dari hasil penelitian beberapa literatur serta fenomena klinis menemukan terjadinya perubahan warna PLV sesaat maupun setelah jangka panjang penggunaan semen resin light dan dual cure. Namun penelitian tersebut menggunakan warna semen serta ketebalan dan warna PLV yang berbeda-beda. Tujuan: Mengevaluasi perubahan warna PLV yang disementasi dengan semen resin light dan dual cure dengan warna semen, ketebalan dan warna PLV yang sama. Metode: 12 PLV IPS Emax 0.5mm, di sementasi dengan semen resin light dan dual cure warna translusen pada model. Perubahan warna PLV setelah sementasi 0 dan 24 jam dievaluasi menggunakan spektrofotometer. Hasil: ?E PLV dengan semen resin light dan dual cure antara 0 dengan 24 jam menunjukkan perubahan warna, namun tidak bermakna p>0.05 . Perubahan terbesar terjadi pada PLV dengan semen resin dual cure. Tidak terdapat perbedaan bermakna antara PLV yang disementasi dengan semen resin light dan dual cure setelah 24 jam p>0.05 . Kesimpulan: Ditemukan perubahan warna pada sementasi PLV dengan semen resin light dan dual cure namun masih dapat diterima secara klinis dan estetik.

ABSTRACT Background Esthetic Porcelain laminate veneer PLV restoration uses resin cements as the adhesive to bond to tooth. PLV rsquo s significant esthetic factor is color match of itself to existing dentition, where cement is one of influencing factors. Controversy of previous studies in literatures and clinical phenomenon found that PLV rsquo s color may change right after cementation using light and dual cure resin cement and after a long term. Nevertheless, those were found using several cement colors on different thickness and colors of PLV. Objectives To evaluate color change of same thickness and color of PLV, cemented with same color light and dual cure resin cement. Methods 12 PLV IPS Emax 0.5mm cemented to models with translucent light and dual cured resin cements. Color change at 0 and 24 hours post cementation were evaluated using spectrophotometer. Result E PLV cemented with light and dual cure resin cements from 0 to 24 hours revealed color difference, however statistically insignificant P 0.05 . PLV with dual cure resin cement has the highest E. There is insignificant difference between E of light and dual cure after 24 hours p 0.05 . Conclusion Color changes of PLV cemented with light and dual cure resin cement are within clinically and esthetically acceptable.
