Background: Since the last few decades, oral cancer as pathology has become an attention in medicine and dentistry. The majority cases of oral cancer are affecting people with smoking habit and alcohol consumption. Many herbs contain substances which can stop cancer cells proliferation, such as Piper retrofractum/Retrofracti fructus, an herb plant from Piperaceae family which contains piperin and piplartin. Purpose: The purpose of this study was to examine the mechanism of piperin and pilplartin as natural oral anticancer drug. Reviews: Piperin and piplartin has function as antioxidant that can protect body cell from damage caused by free radicals. Piperin works synergistically with another bioactive substance like capsaicin and curcumin. Piperin increase the number of serum and life time of serum from a few nutrition substance like co-enzyme Q10 and beta-carotene. Beta-carotene can catch reactive O2 and peroxil radicals. The activity of anticancer piplartin related with obstruction of proliferation cell rate, observe form Ki67 reduction as antigen in nucleus that associated with G1, S, G2, and M phase in cell cycle. Comparing with piplartin, piperin is more potential to inhibit proliferation rate of Ki67, but piplartin’s antiproliferation mechanism will increase if supported by piperin. Conclusion: Piperin and piplartin contained in Javanese chili are potential for natural oral anticancer, by directly or indirectly suppress tumor cell development by increasing the number of immunity cells (immunomodulator), and by inhibiting cell proliferation with reduction of Ki67, nucleus antigen that associated with G1,S,G2, dan M phase of cell cycle.Latar belakang: Sejak beberapa dekade terakhir, patologi kanker rongga mulut telah banyak menjadi perhatian di bidang kedokteran dan kedokteran gigi. Risiko paling tinggi ditemukan pada penderita perokok dan peminum alkohol. Banyak tanaman herbal yang memiliki kandungan untuk menghambat pertumbuhan sel kanker atau antiproliferasi sel, seperti tanaman herbal yang berasal dari suku Piperaceae, salah satunya adalah cabe jawa (Piper retrofractum) yang mengandung piperin dan piplartin. Tujuan: artikel ini bertujuan untuk mengetahui mekanisme kerja piperin dan pilplartin sebagai antikanker alami rongga mulut. Tinjauan pustaka: Piperin dan piplartin berfungsi sebagai antioksidan yang dapat melindungi sel tubuh dari kerusakan akibat radikal bebas. Piperin bekerja secara sinergis dengan zat-zat bioaktif lainnya seperti capsaicin dan curcumin. Piperin meningkatkan jumlah serum dan umur serum dari beberapa substansi nutrisi seperti koenzim Q10 dan betakaroten. Betakaroten mampu menangkap oksigen reaktif dan radikal peroksil. Aktivitas antitumor piplartin berhubungan dengan penghambatan laju proliferasi sel, ditinjau dari reduksi Ki67 yaitu antigen pada inti sel yang berasosiasi dengan G1, S, G2, dan M pada siklus sintesa sel. Dalam mekanisme kerjanya piplartin akan lebih meningkat aktivitas antiproliferasinya jika disinergiskan dengan piperin. Kesimpulan: Piperin dan piplartin yang terkandung dalam cabe jawa berpotensi sebagai antikanker rongga mulut alami, dengan menekan perkembangan sel tumor baik secara langsung maupun tidak langsung melalui peningkatan sel imun (immunomodulator), dengan penghambatan laju proliferasi sel, ditinjau dari reduksi Ki67, yaitu antigen pada inti sel yang berasosiasi dengan G1, S, G2, dan M pada siklus sintesis sel.

Background: Candida isolate is easily sampled from oral cavity by swabbing directly on the candidiasis lesion, to be smeared onto slides for direct examination or cultured in a growth medium. This method is by far the gold standard for defining candidiasis diagnosis. However it is difficult to apply on sensitive patients and almost impossible on patients showing no clinical appearance of oral candidiasis. AIDS patients are very prone to candida infection and have a tendency of repetitive infection involving mixed species. As many candida species show different susceptibility to anti-fungal agents, it is necessary to identify the species causing the infection in the management of oral candidiasis. Oral rinse is a suggested method to obtain candida isolate to be cultured for further analysis such as species identification. This method is simple and less risky on infection transmission as less tools are required in the procedure. Purpose: This study aimed to assess the application of oral rinse as an alternative method to culture Candida isolate from AIDS patients. Methods: A cross-sectional observative study was conducted in HIV/AIDS in-Patient Facility of Intermediate Care Unit for Infection Disease, Dr. Soetomo Hospital Surabaya. Fourteen stadium 4 AIDS patients matching criteria were swabbed on 1/3-posterior of the tongue, and then given 10 ml phosphate buffer saline to rinse vigorously for 15 seconds. Both specimens were cultured on Sabouraud’s dextrose agar and colony growth was observed. Results: Candida colonies were able to grow from all 14 isolates (100%) by both methods. Qualitatively, cultures from oral rinse specimens were more populated than cultures from swab specimens. Conclusion: Oral rinse is an applicable technique to obtain Candida species isolate. This technique is safe, easy, non-invasive, and needs less tools therefore less risky for HIV transmission.Latar belakang: Isolat Candida mudah diambil dengan cara mengusap lesi candidiasis, baik untuk dioleskan pada kaca preparat untuk pemeriksaan langsung maupun dikultur. Hingga kini, metode tersebut dinyatakan sebagai “standar emas” untuk menentukan diagnosis. Namun kekurangan metode ini yaitu berisiko merangsang muntah pada pasien sensitif, dan hanya bisa dilakukan bila tampak jelas ada lesi. Candidiasis adalah penyakit nosokomial yang sering terjadi. Pasien AIDS sangat rentan terhadap infeksi oportunis ini secara rekuren dan persisten. Identifikasi spesies penyebab harus dilakukan karena berbagai spesies Candida memiliki kerentanan yang berbeda terhadap berbagai jenis antifungal. Oral rinse adalah metode pengambilan isolat Candida yang non-invasif. Isolat yang didapat bisa dikultur dan diidentifikasi, selain itu bisa dilakukan pada pasien yang belum menunjukkan adanya lesi candidiasis untuk menentukan besar risiko pasien terkena candidiasis, sehingga dapat ditentukan perlu tidaknya pemberian profilaksis antifungal. Tujuan: Penelitian ini bertujuan mengamati efektivitas metode oral rinse untuk mengisolasi Candida dari rongga mulut pasien AIDS. Metode: Penelitian observasional dilakukan di bagian Rawat Inap Unit Perawatan Intermediate Penyakit Infeksi RSUD Dr. Soetomo. Swab pada 1/3 posterior lidah dilakukan pada 14 pasien yang memenuhi kriteria, kemudia pasien diberi 10 ml phosphate buffer saline untuk berkumur kuat-kuat selama 15 detik. Spesimen yang didapat melalui kedua metode dikultur pada medium Sabouraud untuk diamati. Hasil: Koloni Candida berhasil dikultur dari 14 spesimen (100 %) melalui kedua metode isolasi. Secara kualitiatif tampak bahwa hasil kultur dari oral rinse tampak lebih subur. Kesimpulan: Oral rinse adalah metode yang dapat diaplikasikan untuk mengisolasi Candida dari rongga mulut pasien. Tekniknya mudah, aman, non-onvasif, dan tidak memerlukan peralatan dan ketrampilan khusus, sehingga mengurangi risiko transmisi HIV.

Background: A Q-switched Nd:YAG laser was employed as a source of ablation. The fundamental wavelength of the laser is 1064 nm, with pulse duration of 8 nanosecond operates with uniphase mode of TEM00. In the following experiments, dentin samples (without caries and plaque) are exposed to pulse laser with Q-switching effect at various energy dose. Purpose: The aim of this study was to investigate the effect of laser ablation on dentin samples using Q-switched Nd:YAG laser exposure. Methods: The laser was operated in repetitive mode with frequency of 10 Hz. The energy dose of the laser was ranging from 13.9 J/cm2, 21.2 J/cm2 and 41.7 J/cm2. The target material comprised of human dentin. The laser was exposed in one mode with Q-switched Nd:YAG laser. Energy delivered to the target through free beam technique. The exposed human dentin was examined by using x-ray diffraction (XRD) and fluoresence scanning electron microscopy for energy dispersive (FESEM-EDAX). Microhardness of human dentin were examined by using microhardness vickers test (MVT). Results: The result obtained showed that the composition of hydroxyapatite of the dentin after exposed by Q-switched Nd:YAG laser are 75.02% to 78.21%, with microhardness of 38.7 kgf/mm2 to 86.6 kgf/mm2. This indicated that exposed pulsed Nd:YAG laser on the human dentin attributed to the phototermal effect. The power density created by the Q-switched Nd:YAG laser enables the heat to produce optical breakdown (melting and hole) associated with plasma formation and shock wave propagation, from energy dose of 21.2 J/cm2. From XRD analysis showed that the exposure of Nd:YAG laser did not involve in changing the crystal structure of the dentin, but due to photoablation effect. Conclusion: In conclusion, the application of Q-switched Nd:YAG laser as contactless drills in dentistry should be regarded as an alternative to the classical mechanical technique to improve the quality of the dentin treatment.Latar belakang: Mode Q-Switch pada laser Nd:YAG dapat menghasilkan fenomena ablasi pada dentin. Laser Nd:YAG yang digunakan mempunyai panjang gelombang 1064 nm, durasi pulsa 8 ns beroperasi dengan mode TEM00. Sampel dentin yang digunakan tanpa karies dan plak, yang dipapari laser dengan mode Q-switch dalam berbagai variasi dosis energi. Tujuan: Tujuan penelitian ini adalah mengamati efek ablasi dentin secara in vitro akibat paparan laser Nd:YAG Q-switch dengan pengamatan morfologi permukaan, komposisi hidroksiapatit, dan uji kekerasan mikro. Metode: Laser Nd:YAG Q-switch dengan frekuensi 10 Hz dan variasi dosis energi 13,9 J/cm2, 21,2 J/cm2 dan 41,7 J/cm2 ditembakkan pada sampel dentin manusia dengan teknik penyinaran bebas tanpa dilewatkan serat optik. Dentin yang terbuka diamati menggunakan x-ray diffraction (XRD) dan fluoresence scanning electron microscopy for energy dispersive (FESEM-EDAX). Kekerasan mikro dari dentin juga diamati menggunakan microhardness vickers test (MVT). Hasil: Hasil penelitian menunjukkan bahwa komposisi hidroksiapatit dari dentin setelah paparan laser Nd:YAG Q-Switch menunjukkan peningkatan berkisar 75,02% sampai 78,21% dibandingkan normal, dengan kekerasan mikro berkisar 38,7 kgf/mm2 sampai 86,6 kgf/mm2. Perubahan pada struktur mikro tersebut disebakan karena adanya efek fototermal. Kerapatan daya yang bervariasi berdasarkan variasi dosis energi menyebabkan efek panas pada dentin yang menyebabkan adanya fenomena optical breakdown, yang ditandai dengan munculnya efek leleh dan lubang pada sampel karena produksi plasma dan adanya gelombang kejut, mulai dosis 21,2 J/cm2. Berdasarkan uji XRD, efek yang muncul pada dentin tidak menyebabkan terjadinya perubahan struktur kristal hidroksiapatit, tetapi menyebabkan perubahan komposisi hidroksiapatit yang disebut dengan fotoablasi. Kesimpulan: Dapat disimpulkan bahwa penggunaan mode Q-switched pada laser Nd:YAG sebagai alat dengan kontak minimal dapat dijadikan teknik alternatif untuk meningkatkan kualitas perawatan dental.

Volatile sulphur compounds elimination: A new insight in periodontal treatment Ernie Maduratna Setiawatie; Rikko Hudyono
Dental Journal (Majalah Kedokteran Gigi) Vol. 44 No. 4 (2011): December 2011
Publisher : Faculty of Dental Medicine, Universitas Airlangga https://fkg.unair.ac.id/en

Background: Recent evidences had demonstrated a link between halitosis and apoptosis in periodontitis. Periodontal pathogenic micro-organisms produce volatile sulphur compounds (VSCs). VSCs are toxic to periodontal tissue. Purpose: The purpose of this paper was to reveal the mechanism of VSCs in periodontal breakdown according to the most recent knowledges. Reviews: Halitosis is mainly attributed to VSCs such as hydrogen sulfide, methyl mercaptan and dimethyl sulfide. Several studies demonstrated a strong relationship between VSCs and periodontal disease progression. VSCs are released from amino acid breakdown from food, protein, cells, blood and saliva. In prone subjects, the VSCs may cause alteration in tissue integrity by increasing its permeability and facilitate the endotoxin to penetrate the tissue barrier. They may also causing apoptotic in gingival and periodontal tissue, which are considered the main pathogenesis in aggravating the periodontitis. VSCs may also initiate the increase of proinflammatory cytokines which is considered to have negative effects in host response. Conclusion: VSCs had been shown to have detrimental effects in gingival and periodontal ligament cells. The use of chlorine dioxine agent and topical antioxidant is beneficial in controlling the periodontal disease severity.Latar belakang: Penelitian terakhir menunjukkan adanya hubungan antara halitosis dengan terjadinya apoptosis pada periodontitis. Mikroorganisme penyebab periodontitis memproduksi volatile sulphur compounds (VSCs) yang bersifat toksik terhadap jaringan periodontal. Tujuan: Tujuan penulisan ini adalah membahas mekanisme VSCs dalam menyebabkan kerusakan periodontal berdasarkan penelitian terakhir yang ada. Tinjauan pustaka: Halitosis seringkali dikaitkan dengan timbulnya VSCs seperti hidrogen sulfida, metil merkaptan, dan dimetil sulfida. Penelitian terakhir menunjukkan bahwa VSCs yang dilepaskan dari pemecahan asam amino makanan ternyata memiliki korelasi dengan kerusakan jaringan periodontal. Pada subjek yang peka, VSCs dapat menyebabkan terjadinya disintegritas epitel dengan meningkatkan permeabilitasnya sehingga endotoksin dapat masuk melewati epitel. Adanya VSCs tersebut memicu terjadinya apoptosis pada jaringan gingiva dan ligamen periodontal, dimana proses ini menyebabkan keparahan penyakit periodontal. VSCs juga dapat mencetuskan peningkatan sitokin proinflamasi yang dapat menyebabkan kerusakan jaringan periodontal. Kesimpulan: VSCs dapat menyebabkan kerusakan pada gingiva dan ligamen periodontal. Penggunaan bahan chlorine dioxine untuk dan antioksidan topikal sangat berguna dalam mengontrol keparahan penyakit periodontal.
