Abstract

Background: Acrylic resin was a material of denture base which frequently used, but it still had a weakness that it was porous, then, it was often the breeding ground of Candida albicans. Virgin coconut oil (VCO) contained fatty acid which was effective to hamper the growth of C.albicans. Objective: This research was to identify the effect of VCO on the growth of C.albicans on acrylic resin denture. Methods: This research was an experimental laboratory research which exerted post-test control group design. The total sample 24 which were divided into 3 groups of treatment and 1 group of control. The treatment covered acrylic plates soaking which have been contaminated with C.albicans suspension into VCO in concentration level 25%, 50%, 75%, and sterile aquades for 8 hours. The acrylic plate was vibrated to knock out C.albicans and was then continued by colony counting on the media of Sabouraud Dextrose Agar (SDA). The statistic test employed Kruskal-Wallis and continued to the Post-Hoc test which employed Mann-Whitney. Findings: The VCO in concentration level 25%, 50%, and 75% affected to inhibit the growth of C.albicans. In the Kruskal-Wallis test, it was found a significant difference between the number of C.albicans on the control group and the VCO in concentration level 25%, 50%, and 75% (p<0,05). The Post-Hoc Mann-Whitney test indicated no significant difference between VCO in concentration level 25% and 50%, 25% and 75%, also 50% and 75% (p>0,05). Conclusion: The VCO in concentration level 25%, 50%, and 75% affected was able to hamper the growth of C.albicans. Further, there was no significant difference in each VCO concentration.

Abstract

Latar Belakang: Karies gigi masih merupakan masalah utama dari sekian banyak masalah kesehatan gigi dan mulut di dunia. Karies gigi terutama terjadi pada anak usia Sekolah Dasar dimana angka kejadian karies sangatlah tinggi. Oleh karena itu diperlukan upaya pencegahan. Salah satu upaya pencegahan karies dapat dilakukan dengan konsumsi probiotik dalam bentuk permen karet. Lactobacillus reuteri dalam permen karet memproduksi zat reuterin yang dapat berfungsi sebagai antimikroba yang dapat menghambat pertumbuhan bakteri dan menghambat pembentukan plak gigi.Tujuan: Membuktikan efektifitas permen karet probiotik dalam menurunkan indeks plak dan jumlah koloni Streptococcus sp. saliva pada siswa kelas 5 Sekolah Dasar Ungaran 02.Metode: Penelitian ini merupakan penelitian eksperimental dengan rancangan one group pretest-posttest design. Subjek penelitian adalah 10 siswa kelas 5 Sekolah Dasar yang tercatat sebagai siswa di SD Ungaran 02, Kelurahan Ungaran, Kecamatan Ungaran Barat, Kota Semarang, Provinsi Jawa Tengah yang memenuhi kriteria penelitian. Data karakteristik yang diambil adalah indeks plak dan jumlah koloni Streptococcus sp. saliva yang diukur sebanyak dua kali yaitu sebelum dan sesudah pemberian permen karet yang mengandung probiotik satu kali sehari selama 2 minggu. Data kemudian diolah menggunakan uji paired t test dan uji pearson.Hasil: Permen karet probiotik mampu menurunkan Indeks plak dan Jumlah koloni Streptococcus sp. . Analisis uji t berpasangan menunjukan indeks plak sebelum diberi permen karet probiotik 2,30 ± 0,19 berbeda bermakna dengan indeks plak sesudah 1,92 ± 0,30(p < 0,05). Analisis uji t berpasangan menunjukan jumlah koloni Streptococcus sp.(106CFU/ml) saliva sebelum diberi permen karet probiotik 225,60 ± 53,66 berbeda bermakna dengan jumlah koloniStreptococcus sp. (106CFU/ml) saliva sesudah 113,90 ± 28,88 (p < 0,05) dengan korelasi sangat kuat antara indeks plak dengan jumlah koloni Streptococcus sp. Kesimpulan: permen karet probiotik efektif dalam menurunkan nilai indeks plak gigi dan jumlah koloni Streptococcus sp. saliva pada siswa kelas 5 Sekolah Dasar Ungaran 02.

Abstract

Background: The color of teeth in each individual varies greatly in which it is influenced by the color of dentin and enamel. The most frequent tooth discoloration that happened is caused by extrinsic stains like coffee. Coffee consumption habits are increasing along with the level of creativity in serving coffee. Nowadays, coffee with conventional methods like black/Turkish coffee and manual brewing methods such as drip brewing and espresso become popular coffee that are fancied by Indonesian people. Exposure to chromogenic substances and the acidic nature of coffee can cause the formation of pores in enamel and facilitate the deposition of dyes, which cause the color changes. Aim: The aim of this research was to analyze the effect of brewing methods on tooth discoloration. Method: This research was a true experimental study with a pre-post test control group design. Twenty eight post-extracted first premolar teeth samples divided into 4 groups for drip, espresso, black coffee and control by implementing random allocation. All samples were immersed in each coffee brewing group for 3 hours, 6 hours, and 9 hours. The teeth color was measured using a Chromameter based on the CIE L*a*b system. Statistical tests used Kruskal Wallis and Mann-Whitney test. Result: The Kruskal Wallis test showed differences in the color change ∆a * between the four groups (p < 0.05). Mann-Whitney test indicated a significant difference between the treatment group (drip, espresso, and black coffee group) and the control group (p < 0.05). Conclusion: Drip coffee, espresso and black coffee brewing methods can affect tooth discoloration, especially affects the red discoloration. But there is no difference in the effect of the drip, espresso, and black coffee brewing methods on tooth discoloration.
