Abstract

Oil palm empty fruit bunch (OPEFB) fibers have emerged as a promising natural alternative to synthetic fibers due to their mechanical strength and biocompatibility, although research on their use as a reinforcing in composite resin remains limited. This study aimed to evaluate the effect of OPEFB fiber incorporation on the compressive strength of flowable composite resin. A true experimental design with a post-test-only control group was employed. The OPEFB fibers underwent chemical and double silane treatments and were randomly oriented prior to incorporation. Fifteen cylindrical specimens (6 mm × 12 mm) were allocated into three groups based on fiber volume fraction (0%, 1%, and 1.5%). Compressive strength was tested using a universal testing machine following ASTM D-695 standards. Data were analyzed using one-way ANOVA (p < 0.05) followed by a post-hoc Least Significant Difference (LSD) test. The mean compressive strength of flowable composite resins at 0%, 1%, and 1.5% OPEFB fiber volume fractions were 261.99 ± 17.64, 301.20 ± 19.26, 368.52 ± 14.90 MPa. One-way ANOVA test showed that the mean compressive strength in the three groups was significantly different (p < 0.05). The post-hoc LSD test showed significant differences (p < 0.05) among all groups. This study concluded that the incorporation of OPEFB fiber can enhance the compressive strength of flowable composite resin, with the highest reinforcement observed at the 1.5% OPEFB fiber volume fraction.

Abstract

Early Childhood Caries (ECC) merupakan salah satu masalah kesehatan gigi dan mulut yang paling sering terjadi pada anak usia dini dan dapat berdampak jangka panjang terhadap kualitas hidup anak. Tingginya prevalensi ECC di Indonesia tidak terlepas dari rendahnya pengetahuan dan keterampilan dalam perawatan gigi anak, baik di lingkungan keluarga maupun sekolah. Guru taman kanak-kanak (TK) dan preschool memiliki peran strategis dalam membentuk kebiasaan hidup sehat anak sejak usia dini. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan guru TK dan Preschool Al-Biruni Kota Padang dalam pencegahan ECC melalui edukasi perawatan gigi anak usia dini. Metode yang digunakan meliputi sosialisasi, penyuluhan interaktif, pelatihan praktik menyikat gigi anak, serta evaluasi menggunakan pre-test dan post-test. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan guru secara signifikan, ditandai dengan hasil post-test yang mencapai 100% jawaban benar pada seluruh indikator penilaian. Evaluasi lanjutan enam bulan setelah kegiatan menunjukkan adanya perubahan perilaku di lingkungan sekolah berupa penerapan kebiasaan menyikat gigi bersama setelah sarapan. Kegiatan ini membuktikan bahwa edukasi terstruktur kepada guru efektif sebagai upaya pencegahan ECC yang berkelanjutan di lingkungan pendidikan anak usia dini.

Abstract

Introduction: Composite resin is a restorative material that bonds to tooth structure through micromechanical interlocking. Etching removes the smear layer and creates microporosities, enhancing mechanical retention. Although 37% phosphoric acid is the gold standard, it may cause inflammatory cell infiltration. Averrhoa bilimbi L. contains citric, oxalic, and lactic acids, which may serve as a natural alternative etching agent for enamel. This study aimed to analyze the effect of Averrhoa bilimbi L. extract gel as a natural enamel etching agent on the tensile bond strength of composite resin restorations. Methods: This was an in vitro laboratory true experimental study that employed a post-test-only control group design. Twenty-eight extracted human premolars were divided into four groups (n = 7): three experimental groups etched with 2.5%, 5%, and 7.5% Averrhoa bilimbi L. extract gel, and one control group etched with 37% phosphoric acid. After etching, bonding agent and microhybrid composite resin were applied. Tensile bond strength was tested using a Universal Testing Machine, and data were analyzed using the Shapiro–Wilk, Levene’s, and Kruskal–Wallis tests. Results: The highest mean tensile bond strength was observed in the 37% phosphoric acid group (7.56 ± 3.87 MPa), followed by 7.5% (6.71 ± 1.71 MPa), 5% (6.17 ± 1.39 MPa), and 2.5% (6.04 ± 3.01 MPa) Averrhoa bilimbi L. extract groups. The Kruskal-Wallis test showed p=0.874, indicating no statistically significant difference between the groups. Conclusion: Averrhoa bilimbi L. extract gel demonstrated a tensile bond strength comparable to that of 37% phosphoric acid. The extract gel demonstrated promising potential as a natural etching agent; however, further laboratory and clinical studies are required before it can be recommended for clinical application.
