BACKGROUND: Herbal mouthwash is considered as an alternative regimen in maintaining oral hygiene. Tea contains compounds such as catechin and tannin which possess bactericidal and bacteriostatic effect which helps to prevent dental caries. AIM: This study was conducted to determine the effectiveness between rinsing with steeping black tea and green tea solution in decreasing the amount of Streptococcus mutans. METHODS: This is an experimental study with pre and post-test controlled group design. The sample were 60 college students from North Sumatera University which were then divided into three groups: oral rinsing with steeping black tea (treatment group), oral rinsing with steeping green tea (treatment group) and oral rinsing with listerine (control group). Saliva collection was carried out before treatment (pre-test/baseline) and after treatment (post-test). Treatment group was instructed to rinse 15 ml of steeping black and green tea solution whereas control group were instructed to rinse 15 ml listerine for 30 seconds and get rid of it. The saliva samples before and after treatment were brought to the microbiology laboratorium for Streptococcus mutans amount calculation using Total Plate Count (TPC) method. A T-test were used to determine the difference between rinsing with black tea and green tea and Kruskalwalis used to determine the difference between rinsing with steeping black tea, steeping green tea and aquadest towards the mean amount of bacteria before and after treatment. RESULT: The results showed significant reduction in amount of Streptococcus mutans in both treatment group where black tea group before treatment 28.90 x 103 ± 7.152 x 103 CFU/ml and after treatment 21.60 x 103 ± 6.295 x 103 CFU/ml (p < 0.05) and green tea group before treatment 70.15 x 103 ± 34.814 x 103 CFU/ml and after treatment 54.85 x 103 ± 31.451 x 103 CFUml (p < 0.05). The results in control group also showed reduction in amount of Streptococcus mutans where before treatment 25.80 x 103 ± 12.190 x 103 CFU/ml and after treatment 11.30 x 103 ± 8.228 x 103 CFU/ml (p > 0.000). Statistical analysis revealed that significant difference was found in the mean reduction of total Streptococcus mutans before and after in black tea group 7.30 x 103 ± 3.062 x 103 CFU/ml and green tea group 15.30 x 103 ± 11.045 x 103 CFU/ml (p < 0.05). CONCLUSION: It can be concluded that rinsing with steeping green tea solution has more effectiveness in decreasing the total Streptococcus mutans as compared to black tea solution.

Abstract__ Herbal mouthwash is considered as an alternative regimen in maintaining oral hygiene. Tea contains compounds such as catechin and tannin which possess bactericidal and bacteriostatic effect which helps to prevent dental caries. This study was conducted to determine the effectiveness between rinsing with steeping black tea and green tea solution in decreasing the amount of oral bacteria. This is an experimental study with pre and post test controlled group design. The sample were 90 Junior High School students from Swasta Namira School which were then divided into three groups: oral rinsing with steeping black tea (treatment group), oral rinsing with steeping green tea (treatment group) and oral rinsing with aquadest (control group). Saliva collection was carried out before treatment (pre test/ baseline) and after treatment (post test). Treatment group was instructed to rinse 15 ml of steeping black and green tea solution whereas control group were instructed to rinse 15 ml aquadest for 30 seconds and get rid of it. The saliva samples before and after treatment were brought to the microbiology laboratorium for bacteria amount calculation using Total Plate Count (TPC) method. A T-test were used to determine the difference between rinsing with black tea and green tea and Kruskalwalis used to determine the difference between rinsing with steeping black tea, steeping green tea and aquadest towards the mean amount of bacteria before and after treatment. The results showed significant reduction in amount of bacteria in both treatment group where black tea group before treatment 1002.13x10 ±494.55x103 CFU/ml (p>0.05). Thus, it can be concluded that rinsing with steeping black tea solution has the same effectiveness in decreasing the total oral bacteria as compared to green tea solution.

Kerusakan pada gigi atau karies merupakan penyakit yang paling umum terjadi pada anak-anak. Karies gigi yang tidak dirawat dapat mengakibatkan pulpitis, ulserasi, fistula dan abses (pufa) yang dapat berdampak terhadap kualitas hidup anak. Penelitian ini bertujuan untuk mengetahui hubungan skor pufa dengan kualitas hidup pada siswa usia 6-8 tahun di 2 SD Negeri kota Medan. Jenis penelitian adalah cross sectional study dengan populasi siswa usia 6-8 tahun di SD Negeri 060889 dan 060894 kota Medan. Seluruh populasi dijadikan sampel berjumlah 206 orang. Pengumpulan data akibat karies yang tidak dirawat menggunakan indeks pufa dan skor kualitas hidup menggunakan indeks Child Perceptions Questionnaire (CPQ). Hubungan skor pufa dengan kualitas hidup dianalisis menggunakan chi square test. Hasil penelitian menunjukkan rerata skor pufa 0,85 ± 0,93 dan sebagian besar responden memiliki kualitas hidup baik yaitu 62,8%, cukup 30,8% dan buruk 6,6%. Ada hubungan yang signifikan antara skor pufa dengan kualitas hidup pada anak SD Negeri di kota Medan (p= 0,000). Semakin meningkat skor pufa, persentase kualitas hidup baik semakin menurun, sebaliknya persentase kualitas hidup sedang dan buruk semakin meningkat. Sebagai kesimpulan, ada hubungan yang signifikan antara skor pufa dan kualitas hidup pada siswa SD.

Angular cheilitis adalah suatu keadaan inflamasi yang akut atau kronik pada kulit yang berdekatan dengan membran mukosa labial sudut mulut. Status pertumbuhan dan nutrisi anak pada masa pra sekolah dan sekolah dipengaruhi diet yang mereka konsumsi. Desain penelitian adalah studi cross sectional. Populasi adalah anak panti asuhan SOS Childrens Village dan panti asuhan Al-Jamiatul Wasliyah Medan yang berjumlah 262 anak. Jumlah sampel 174 orang dengan kriteria inklusi anak umur 6-12 tahun. Pengambilan data diperoleh dengan pemeriksaan Angular cheilitis pada sudut bibir. Tujuan penelitian ini untuk mengetahui hubungan antara status gizi dengan prevelensi Angular cheilitis, uji statistik yang digunakan adalah chi-square. Hasil penelitian menunjukkan 37,4% anak panti asuhan mengalami angular cheilitis, sebanyak 24,2% anak di panti asuhan berstatus gizi dibawah normal. Ada hubungan yang signifikan antara status gizi dengan prevalensi Angular cheilitis (p= 0,002).

Prosedur kontrol infeksi yang umum dilakukan adalah dengan menerapkan standard precautions berdasarkan peraturan yang dikeluarkan oleh Centers for Disease Control and Prevention (CDC). Tujuan penelitian ini adalah untuk mengetahui tingkat pengetahuan mahasiswa kepaniteraan klinik tentang standard precautions operator sebelum dan setelah perawatan gigi. Penelitian ini merupakan penelitian survei deskriptif yang dilakukan dengan cara membagikan kuesioner pada mahasiswa kepaniteraan klinik yang terdiri atas 26 pertanyaan untuk sebelum dan 32 pertanyaan untuk setelah tindakan perawatan gigi. Data diolah secara manual dan dianalisis dengan analisis univariat. Hasil penelitian pengetahuan responden tentang standard precautions sebelum tindakan perawatan yang berpengetahuan kurang 69,8%, 29,3% cukup, 1% responden yang berpengetahuan baik. Setelah perawatan gigi didapat 54,5% responden memiliki pengetahuan cukup, 37,5% berpengetahuan baik, dan hanya 8% responden berpengetahuan kurang. Sebagai kesimpulan,  pengetahuan mahasiswa kepaniteraan klinik tentang standard precautions operator sebelum dan setelah perawatan gigi masih kurang.
