Red dragon fruit flesh extract contains of anthocyanin as red pigmen that potentially to be a natural dye. Athocyanin contains of polysaccharide that can binding with polysaccharide of dental plaque called hydrogen bonds, so dental plaque has been colored and potentially as alternative of disclosing solution. The purpose of this study was to find out the difference of plaque index after smeared by red dragon fruit flesh extract 75% and disclosing solution. The method of this study is a clinical experimental study with a static-group comparison design. 20 subjects were examined the plaque index after smeared with red dragon fruit flesh extract 75%) and disclosing solution). There was no significant difference between groups. Conclusions: Red dragon fruit flesh extract 75% had similar capability with disclosing solution to examine dental plaque.

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

Pendahuluan: Tunanetra merupakan istilah yang digunakan untuk kondisi seseorang yang mengalami gangguan dalam indera penglihatannya. Keterbatasan fisik yang dialami oleh tunanetra menyebabkan pengetahuan tentang kesehatan gigi dan mulut sulit didapatkan dan cenderung memiliki tingkat kebersihan gigi dan mulut yang rendah. Oleh karena itu diperlukan pendekatan khusus agar pengetahuan dan kebersihan gigi dan mulut dapat meningkat. Tujuan penelitian ini untuk menganalisis pengaruh edukasi kesehatan gigi dan mulut berbasis Braille terhadap tingkat kebersihan gigi dan mulut penyandang tunanetra. Metode: Jenis penelitian ini merupakan pre-eksperimental dengan desain penelitian one-group pretest-posttest design. Subjek penelitian berjumlah 18 siswa penyandang tunanetra SLB-A TPA dan SLB Negeri Jember yang diberikan edukasi berupa buku panduan kesehatan gigi dan mulut berbasis buku Braille. Subjek diminta untuk menjaga kebersihan gigi dan mulut salah satunya dengan menyikat gigi dua kali sehari selama 21 hari. Pengukuran tingkat kebersihan gigi dan mulut dilakukan menggunakan indeks OHI-S Green dan Vermillion. Pengukuran dilakukan pada hari ke-1 (evaluasi 1) sebelum diberi perlakuan dan pelatihan sikat gigi, hari ke-10 (evaluasi 2), dan hari ke-21 (evaluasi 3). Data dianalisis dengan uji komparatif parametrik paired sample t-test. Hasil: Distribusi data adalah normal dengan p-value (p>0,05) sebesar 0,200 (evaluasi 1), 0,126 (evaluasi 2), dan 0,118 (evaluasi 3). Edukasi yang diberikan selama 10 hari tidak menurunkan indeks OHI-S dengan p-value 0,317 (p>0,05). Edukasi selama 21 hari dapat menurunkan indeks OHI-S dengan p-value sebesar 0,000 (p<0,05). Simpulan: Pemberian edukasi kesehatan gigi dan mulut berbasis buku Braille pada penyandang tunanetra di SLB-A-TPA dan SLB Negeri   Jember berpengaruh terhadap peningkatan kebersihan gigi dan mulut.Kata kunci: Tunanetra, edukasi, Braille, kebersihan gigi dan mulut, OHI-S. ABSTRACTIntroduction: Visual impairment is a term used for the condition of a person who has a disturbance in the sense of sight. Physical limitations experienced by visually impaired individual make the knowledge regarding oral health difficult to obtain and tends to have a low level of oral hygiene. Therefore, a personal approach is needed so that the oral health knowledge and oral hygiene can be improved. This study was conducted to analyse the effect of Braille-based oral health education on the level of the visually impaired students’ oral hygiene. Methods: This research was pre-experimental research with a one-group pretest-posttest design. Research subjects were 18 students with a visual impairment from Special School-A TPA and Public Special School of Jember who were given education in the form of oral health manuals in the form of Braille books. Subjects were asked to maintain their oral hygiene by brushing their teeth twice a day for 21 days. Measurement of the oral hygiene level was carried out using the Green and Vermillion OHI-S index. Measurements were made on day 1 (evaluation 1) before being treated and trained in toothbrushes; day 10 (evaluation 2); and day 21 (evaluation 3). The data were analysed by the paired sample t-test parametric comparative analysis. Results: Data distribution was normal with p-value > 0.05 of (p = 0.200) (evaluation 1), 0.126 (evaluation 2), and 0.118 (evaluation 3). The counselling was conducted for ten days and had not reduced the OHI-S index, with a p-value of 0.317 (p > 0.05). Counselling then continued for 21 days and was able to reduce the OHI-S index with a p-value of 0.000 (p < 0.05). Conclusion: Providing Braille books-based oral health education to visually impaired students in Special School-A TPA and Public Special School of Jember improving their oral hygiene.Keywords: Visual impairment, education, Braille, oral hygiene, OHI-S.

Lime juice contains some organic acids. It is a plant that is widely consumed by people.Organic acid content causes the lime has an acidic pH. The consumption of beverages containing excess acid may cause tooth erosion due to demineralizationonenamel surface.Demineralization happens constantly causes the loss of some enamel prismata and formamicroporosityinthe enamel. This research wasconducted to measure the depth of enamel microporosity of the teeth enamel is soaked in limejuice. Samples were maxillary first premolar teeth which were divided into two groups: control (soaked in artificial saliva)and treatment (soaked in lime juice) respectively for 5 and 10 minutes. Depth measurement of enamel microporosity wasmeasuredby using a scanning electron microscope, which showed no significant difference (α<0.05) between the depth ofthe microporosity of the enamel were soaked lemon juice for 5 minutes and 10 minutes. It was concluded that the longer thetooth enamel soaking in lime juice causes deeper microporosity.

(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.
