Nanohybrid resin composite is one of the restorative dental materials that has goodaesthetic value and smooth surface. However, resin composite can be discolored due toconsuming foods and beverages, one of which is a carbonated beverage. To determine the difference of discoloration of polished and unpolished nanohybrid resin compositeafter the immersion in carbonated beverage. An experimental laboratories research withthe post test only control group design. In the group of polished composite, polishing wasdone on one side only, while the unpolished composit group, any treatment wasn't done.The total were 32 samples, divided into 4 groups which were immersed in carbonatedbeverages and artificial saliva for 7 days. The shredded material was replaced every 24hours. The instrument used for testing the discoloration was a spectrophotometer. Datawas analyzed by parametric statistical test One-way ANOVA and LSD (Least SignificantDifferent). There were significant differences between the unpolished composite resin thatsoaked in carbonated beverages and the other groups (p <0.05). Unpolished resincomposite are prone to discolorate compared to the polished resin composite

(p=0,004). It can be concluded that the overall perceptions of the rural community is poor.

Penelitian ini bertujuan untuk mengetahui persepsi masyarakat yang mengalami kehilangan gigi terhadap pemakaian gigitiruan berdasarkan kelompok usia, jenis kelamin, dan tingkat pendidikan di Desa Ujung Rambung Kecamatan Pantai Cermin Kabupaten Serdang Bedagai pada bulan Februari 2010. Penelitian bersifat observasional analitik. Jumlah sampel 200 orang yang kehilangan minimal satu gigi, tetapi tidak termasuk gigi molar tiga. Uji chi-square menunjukkan tidak ada hubungan yang signifikan antara persepsi penampilan, pengunyahan, dan pengucapan dengan kelompok usia, antara persepsi penampilan, pengunyahan, dan pengucapan dengan jenis kelamin, dan antara persepsi pengunyahan dan pengucapan dengan tingkat pendidikan (p>0,05). Akan tetapi, ada hubungan signifikan antara persepsi penampilan dengan tingkat pendidikan (p=0,004). Disimpulkan bahwa persepsi masyarakat secara keseluruhan menunjukkan hasil yang buruk.
