Abstract

Pendahuluan:Smear layer merupakan suatu lapisan yang terbentuk dari sisa-sisa debris pasca instrumentasi yang tersusun dari komponen organik dan anorganik. Smear layer yang tidak dibersihkan dapat mengganggu pelekatan suatu bahan restorasi ke dalam dinding kavitas serta dapat menjadi host bagi mikroorganisme.. Salah satu bahan dentin conditioner yang biasa digunakan adalah asam  poliakrilat 10%. Bahan alami yang dapat digunakan sebagai alternatif dentin conditioner untuk meminimalisir efek samping bahan kimia adalah ekstrak buah okra hijau karena memiliki kandungan yang bersifat asam dan mengandung senyawa saponin yang bersifat sebagai surfaktan alami. Penelitian ini bertujuan untuk mengetahui kemampuan ekstrak buah okra hijau dalam membersihkan smear layer pada permukaan kavitas dan membandingkan kemampuan ekstrak buah okra hijau dengan asam poliakrilat 10% dalam membersihkan smear layer. Metode: Penelitian yang dilakukan merupakan jenis penelitian eksperimental laboratoris untuk mengetahui kemampuan ekstrak buah okra hijau 12,5% dalam membersihkan smear layer dibandingkan dengan asam poliakrilat 10%. 10 elemen gigi dilakukan preparasi kavitas kelas I pada 1/3 tengah permukaan bukal hingga terbentuk kavitas dengan diameter 3 mm dan kedalaman 2 mm. Lima sampel diaplikasikan dengan asam poliakrilat 10% dan lima sampel diaplikasikan dengan ekstrak buah okra hijau 12,5%  sebanyak 6 µL, dibiarkan selama 20 detik, diirigasi kembali dengan aquades 0,5 ml, dan dikeringkan dengan cotton pellet. Setiap sampel dilakukan pemotretan dengan SEM perbesaran 5000x. Hasil pemotretan dilakukan penilaian oleh 3 orang pengamat sesuai skor yang ada. Hasil: Hasil penelitian menunjukkan bahwa kebersihan permukaan kavitas pada kedua kelompok sampel memiliki nilai modus yang sama yaitu 2 (sebagian orifis tubuli dentin terbuka dan terdapat sedikit smear layer). Simpulan: Ekstrak buah okra hijau 12,5% mempunyai kemampuan membersihkan smear layer pada dentin mahkota setara dengan asam poliakrilat 10%.The potential of green okra fruit extract (Abelmoscus esculentus) for cleaning the smear layer on crown dentin cavity: experimental laboratory studyIntroduction: Smear layer is a thin layer formed by post-instrumentation of tooth structure. Smear layers can inhibit dental material bonding to the cavity and can affect as a host for microorganisms. Partial smear layer should be removed using dentin conditioner. One of the commonly used dentin conditioners is 10% polyacrylic acid. The natural ingredient could be used as an alternative dentin conditioner to minimize the side effects of the chemical material above is 12.5% green okra extract because it contains acid and saponin which act as natural surfactants. The aim of the research was to determine the ability of green okra fruit extract to clean the smear layer on cavity surfaces compared to 10% polyacrylic acid. Methods: The research was a laboratory experimental study to determine the ability of 12.5% green okra extract to remove the crown dentin smear layer compared to 10% polyacrylic acid. Ten dental elements were prepared for class I cavity on the middle 1/3 of the buccal surface until reaching a cavity with a diameter of 3 mm and a depth of 2 mm was formed. Five samples were applied with 10% polyacrylic acid and 5 samples were applied with 12.5% green okra fruit extract, 6 µL each group, left for 20 seconds then irrigated with 0.5 ml aquadest and dried with cotton pellet. The samples were examined for their cavity cleanliness score using Scanning electron microscope (SEM) photo with 5000x of magnification. The image results were assessed by 3 observers according to the existing scores. Results: The results showed that the cleanliness of the cavity surface in both sample groups had the same level of cleanliness, score 2 (some of the dentin tubule orifices are open and there is a small smear layer). Both groups have the same score and statistical tests show that there is no significant difference between them. Conclusion: 12.5% green okra fruit extract has the ability to clean the smear layer on crown dentin equal to 10% polyacrylic acid.

Abstract

Introduction: Class V cavity can occur due to horizontal tooth brushing methods. Horizontal brushing and abrasive materials on toothpaste allegedly cause surface roughness in the restorative material. Surface roughness causes the retention of plaque and discoloration that will ultimately affect the aesthetic and durability of the restoration. Glass ionomer cement (GIC), resin-modified glass ionomer cement (RMGIC), and nanofiller composite resin (NCR) are aesthetic restorative materials usually applied to restore the the class V cavity. Objective: To determine the surface roughness of Glass ionomer cement (GIC), resin-modified glass ionomer cement (RMGIC), and nanofiller composite resin (NCR) after brushing with horizontal methods. Methods: This study used a pre and post test control group design. There were three groups, each consisted of 6 samples of bovine’s teeth that was class V prepared and restored. Group 1 NCR, group 2 GIC, and group 3 RMGIC. Each group was brushed with horizontal methods as many as 5,110 movements. The measurements of surface roughness were taken before and after the samples were brushed with surface roughnes tester. Data were statistically analyzed using one way Anova. Result: There were an increase in the surface roughness of each group after brushing. The result showed that the value of surface roughness are as follows GIC > RMGIC > NCR. There were also significant differences among the value of surface roughness in each group. Conclusion: The smallest increase of surface roughness after brushing shows that of nanofiller composite resin, followed by resin-modified glass ionomer cement, and glass ionomer cement.
