Abstract

Penyuluhan kesehatan gigi dan mulut pada anak usia dini sangat penting untuk mengurangi prevalensi karies gigi yang semakin meningkat. Kegiatan ini bertujuan untuk mengevaluasi dampak penyuluhan berbasis media digital terhadap skor OHI-S (Oral Hygiene Index – Simplified) dan indeks DMFT (Decayed, Missing, Filled Teeth) pada anak-anak TK The Naff School Kota Kediri. Metode yang digunakan adalah penyuluhan menggunakan media video animasi dan e-saku gigi yang disampaikan melalui ceramah, demonstrasi, dan evaluasi interaktif. Pelaksanaan kegiatan dilakukan pada Selasa, 28 Oktober 2025, dengan melibatkan mahasiswa Fakultas Kedokteran Gigi Universitas Kadiri, guru, dan dosen sekaligus dokter gigi. Hasil menunjukkan peningkatan signifikan pengetahuan dan kemampuan anak setelah intervensi, tercermin dari perbaikan nilai post-test serta meningkatnya kemampuan anak dalam meniru teknik menyikat gigi dengan benar. Selain itu, analisis statistik menunjukkan adanya korelasi positif yang signifikan antara skor OHI-S dan DMFT (ρ = 0.42; p < 0.001), yang berarti semakin buruk kebersihan gigi, semakin tinggi tingkat keparahan karies. Temuan ini memperkuat bahwa pendekatan edukasi interaktif berbasis media digital efektif dalam membentuk perilaku menjaga kebersihan gigi pada anak usia dini. Selain itu, skor OHI-S dan DMFT menunjukkan perbaikan, yang menunjukkan keberhasilan metode penyuluhan dalam meningkatkan kesadaran dan kebiasaan merawat gigi anak-anak.

Abstract

Zirconia-based ceramic composite resin is a restorative material with high mechanical strength and aesthetic properties, but its solubility in acidic environments remains a concern. Acidic beverages, such as lemon juice (Citrus limon (L.) Burm.), contained citric and ascorbic acids, which could compromise stability in the oral cavity. Therefore, this study aimed to evaluate solubility of zirconia-based ceramic composite resin after immersion in lemon juice. Methods: This laboratory experimental study used a post-test only control group design with 24 zirconia-based ceramic composite resin discs (2 mm thick, 8 mm diameter). Samples were divided into three groups, namely control (immersed in distilled water for 24 hours), as well as immersion in lemon juice for 12 hours and 24 hours. Solubility was measured by weight difference before and after immersion using an analytical balance and calculated with Oysaed & Ruyter’s formula. The collected data were analyzed using the Shapiro–Wilk and Levene tests, followed by Kruskal–Wallis and Mann–Whitney tests. The mean solubility was 0 µg/mm³ in the control group, 0.00018 µg/mm³ in the 12-hour lemon juice group, and 0.00052 µg/mm³ in the 24-hour lemon juice group. Statistical analysis showed significant differences among groups, as evidenced by p < 0.05. Conclusion: Immersion in lemon juice increased solubility of zirconia-based ceramic composite resin. Solubility values were higher with longer immersion time, Keywords: solubility, zirconia-based composite resin, lemon juice, Citrus limon, acidic beverages
