Abstract

Latar belakang: Candida albicans merupakan salah satu flora normal oral yang dapat menyebabkan infeksi pada rongga mulut manusia yang disebut sebagai kandidiasis. Manajemen primer yang sering digunakan dalam mengatasi kandidiasis pada rongga mulut salah satunya adalah nystatin, namun pemberian nystatin hanya terbatas pada pengobatan topikal infeksi kandidiasis kulit dan mukosa karena memiliki spektrum yang sempit dan penyerapan yang buruk pada saluran pencernaan serta memiliki efek samping pada dosis yang tinggi seperti mual ringan, diare, dan muntah. Masyarakat sering menggunakan daun oregano (Origanum vulgare L.) sebagai obat tradisional untuk mengobati berbagai macam penyakit seperti gangguan bronkial, gangguan pencernaan, gatal pada kulit dan flu.Sejumlah penelitian (secara in vitro dan in vivo) juga menunjukkan bahwa daun oregano (Origanum vulgare L.) mengandung beragam senyawa fitokimia seperti fenolik glikosida, flavonoid, tanin, sterol dan terpenoid dalam jumlah tinggi. Tujuan: Mengetahui kadar hambat minimum (KHM) dan kadar bunuh minimum (KBM) ekstrak etanol daun oregano (Origanum vulgare L.) terhadap pertumbuhan Candida albicans secara in vitro. Metode Penelitian: Penelitian ini bersifat eksperimental murni laboratorium secara in vitro dengan cara membandingkan kelompok sampel yang mengandung ekstrak etanol daun oregano dengan konsentrasi 50 mg/ml; 25 mg/ml; 12,5 mg/ml; 6,25 mg/ml; 3,125 mg/ml; 1,562 mg/ml; 0,781 mg/ml; serta kontrol negatif berupa DMSO (Dimethyl Sulfoxide) 10% dan kontrol positif berupa nystatin. Metode yang digunakan yaitu metode broth microdilution pada 96 well plate yang diamati dengan spektofotometri dan uji kadar bunuh minimum (KBM) dengan metode spread pada agar yang dihitung menggunakan colony counter. Hasil Penelitian: Ekstrak etanol daun oregano (Origanum vulgare L.) memiliki kadar hambat minimum (KHM) pada konsentrasi 0,781 mg/ml dan kadar bunuh minimum (KBM) pada konsentrasi 50 mg/ml. Kesimpulan: Ekstrak etanol daun oregano (Origanum vulgare L.) memiliki aktivitas antijamur terhadap pertumbuhan Candida albicans.

Sebagai alternatif lain digunakan tanaman obat seperti lengkuas merah (Alpinia galanga L) yang diduga memiliki aktivitas antijamur. Tujuan penelitian ini adalah untuk mengetahui kadar hambat minimum (KHM) dan kadar bunuh minimum (KBM) ekstrak etanol lengkuas merah terhadap pertumbuhan Candida albicans. Metode: Jenis penelitian eksperimental murni dengan membandingkan kelompok uji yang mengandung ekstrak etanol lengkuas merah (alpinia galanga L) dengan konsentrasi 200mg/ml; 100mg/ml; 50mg/ml; 25mg/ml; 12,5mg/ml; 6,25mg/ml; kontrol positif berupa nistatin, dan kontrol negatif berupa DMSO 10% terhadap pertumbuhan Candida albicans dengan mengamati kekeruhan larutan pada 96 well plate menggunakan spectrophotometer  dan KBM ditentukan menggunakan colony counter dengan pengulangan sebanyak 4 kali. Analisis data menggunakan uji parametrik ANOVA dan uji Post Hoc Tuckey. Hasil: Hasil uji ANOVA nilai p 0,00 yang artinya bahwa kedua data memiliki nilai yang signifikan antar perlakuan, dan uji Post Hoc Tuckey memperlihatkan terdapat perbedaan yang signifikan pada setiap kelompok uji terhadap jumlah Candida. Simpulan: Kadar Hambat Minimum (KHM) ekstrak etanol lengkuas merah (Alpinia galanga L) terhadap pertumbuhan Candida albicancs adalah 200mg/ml namun hanya menghambat 60%, sedangkan ekstrak etanol lengkuas merah (Alpinia galanga L) tidak dapat membunuh Candida albicans.Kata kunci: Candida albicans, lengkuas merah, Alpinia galanga L. ABSTRACTIntroduction: Candida albicans is a pathogenic fungus that can cause oral candidiasis, reaches 20% - 70% prevalence in human. Antifungal drugs often used for oral candidiasis treatment is nystatin, but nystatin has many harmful side effects, and its price is relatively high. Therefore, herbal remedies such as red galangal (Alpinia galanga L.), which presumed to have antifungal activity, can be used as an alternative treatment. The purpose of this research was to determine the minimum inhibitory concentration and a minimum lethal dose of red galangal ethanolic extract on the growth of Candida albicans. Methods: This research was an experimental laboratory, conducted by comparing the test group containing ethanolic extracts of red galangal (Alpinia galanga L.) with the concentrations of 200mg/ml; 100mg/ml; 50mg/ml; 25mg/ml; 12.5mg/ml; and 6.25mg/ml; positive control group was treated with nystatin; and negative control with 10% DMSO. The solutions on 96 well plates were observed with a spectrophotometer, and the minimum killing concentration (MKC) was determined using a colony counter, and the experiment was replicated four times. The result was then analysed with ANOVA parametric test and the Post-Hoc Tuckey test afterwards. Results: The result of the ANOVA test showed that the p-value was < 0.05, which means that all treatments have a significant value, while the Post-Hoc Tuckey test indicated that there were significant differences in each group regarding the number of Candida albicans. Conclusion: Minimum Inhibitory Level (MIC) of red galangal (Alpinia galanga L) ethanolic extract against Candida albicans growth is 200mg/ml but only inhibits 60% of the growth. In contrast, the extract is unable to mortally affects the Candida albicans.Keywords: Candida albicans, red galangal, Alpinia galanga L.

Abstract

Background: Apple cider vinegar potentially can be used as an alternative to irrigation solutions because of its antibacterial compounds that can inhibit Enterococcus faecalis, a pioneer bacteria that cause root canal treatment failure. One of the ideal irrigation solution requirements is that it isn’t toxic to oral cavity tissues, so it’s necessary to run a cytotoxicity test on apple vinegar solution. Cytotoxicity test is the initial part of the evaluation of a dental material before it can be used by humans. Cytotoxicity test was performed on fibroblast cells because the irrigation solution can contact with fibroblast, which are the main cells in the periodontal ligament around the apical. The purpose of this study was to analyze the in vitro cytotoxicity effect of ACV on fibroblast cells.Method: Apple vinegar with concentrations of 0.31%, 0.63%, 1.25%, 2.5%, and 5% was tested using the MTS assay method.Result: The results showed that there was a cytotoxicity effect of apple vinegar solution as a root canal irrigation agent against fibroblasts cell. Apple cider vinegar with concentrations of 1.25%, 2.5%, and 5% are potentially toxic because the percentage of cell viability is less than 70%.Conclusion: There is a cytotoxicity effect of apple cider vinegar solution as a root canal irrigant on fibroblast cells
