Abstract: In this globalization era, Indonesian people especially in Sulawesi Utara are aware of oral health. Their awareness is related to oral diseases as well as aesthetics. Good aesthetics can be achieved by using several methods inter alia composite resin restoration. However, this composite resin undergoes discoloration in the mouth. To overcome the discoloration of the composite resin, alternative materials like acetic acid and lime that can remove the colored substances adhered on the composite resin are introduced. This study was aimed to determine the discoloration of composite resin immersed in acetic solution and in fresh lime juice. This was a true experimental study with a pretest and posttest group design. This study was conducted in 5 days. Daily observation at the same time was perormed by using spectrophotometer to all samples. Data were processed with Microsoft excel and presented in tables. The results showed that based on the spectrophotometer measurement, the composite resins’ color immersed in carbonate solution changed (became brighter) after immersion in acetic solution (from 0.72 to 1.52) and in lime juice (from 0.68 to 1.48). Conclusion: The color of discolored composite resins immersed in acetic acid solution and fresh lime juice became brighter.
Keywords: composite resin, discoloration, acetic solution, lime.

Abstrak: Pada era globalisasi saat ini, masyarakat Indonesia khususnya di Sulawesi Utara mulai sadar akan kesehatan gigi dan mulut. Kesadaran masyarakat tersebut tidak hanya mengenai penyakit gigi dan mulut, melainkan juga masalah estetik gigi. Estetik yang baik dapat dilakukan dengan banyak cara, salah satunya tindakan penumpatan dengan menggunakan resin komposit. Resin komposit memiliki kecenderungan berubah warna pada saat digunakan di rongga mulut. Perubahan warna menjadi penyebab diperlukannya penggantian bahan tumpatan (resin komposit). Untuk menghemat biaya terdapat alternatif lain seperti asam cuka (asam asetat) dan jeruk nipis yang dapat mengangkat zat-zat warna yang menempel pada resin komposit. Penelitian ini bertujuan untuk mengetahui perubahan warna resin komposit yang direndam dalam larutan cuka dan perasan jeruk nipis. Jenis penelitian ialah eksperimental semu dengan pretest and posttest group design. Penelitian dilakukan selama 5 hari dan dilakukan pengamatan setiap harinya pada jam yang sama dengan menggunakan alat spektrofotometer untuk sampel larutan cuka dan sampel jeruk nipis. Data hasil penelitian diolah menggunakan program komputer microsoft excel dan disajikan dalam bentuk tabel. Hasil penelitian menunjukkan adanya peningkatan warna resin komposit yang direndam dalam larutan karbonasi selanjutnya direndam dalam larutan cuka dari 0,72 menjadi 1,52 dan dalam jeruk nipis dari 0,68 menjadi 1,48. Simpulan: Terdapat perubahan warna lebih cerah pada resin komposit yang direndam pada larutan cuka dan jeruk nipis.
Kata kunci: Resin komposit, perubahan warna, larutan cuka, jeruk nipis
