Abstract

Background: Osteoporosis is a systemic disease that can decrease bone density as a result of imbalance bone remodeling and bone resorption. Estrogen reduction due to menopause can increase osteoclast activity and furthermore decrease bone density. Estrogen can stimulate alkaline phosphatase (ALP) expression, collagen type I and osteocalcin in bone remodelling process. Ovariectomized rat is a common animal for studying patofisiology, diagnosis and treatment osteoporosis patient. Purpose: To evaluate correlation between estrogen and ALP expression in osteoporotic rat model mandible. Methode: 18 female wistar rats, 2 months old, 200 grams were divided into 2 groups, ovariectomized group and sham surgery as control group. Surgery was done under intra muskular anesthesia using combination 2% xylazine 1cc and 10% ketamine 1cc. After 12 weeks, mandible was taken for ALP examination and blood from heart was taken to evaluate the amount of estrogen. Result: There was significant correlation between estrogen and ALP expression in osteoporotic rat model mandible. Conclusion: The amount of estrogen can influence ALP expression activity.

Abstract

Background: Musculoskeletal complaints have been common for dentists since their body is unknowingly often in inappropriate positions when caring for patients. For example, they bend towards patients, suddenly move, and then rotate from one side to another. The repetitive movements are done in long term. High activities and sufficient recovery time can cause a buildup of lactic acid in their blood leading to obstruction of the energy intake from the aerobic system in their muscle cells, resulting in fatigue. As a result, such conditions trigger decreased muscle performances. Purpose: This study aimed to determine the correlation between working positions and lactic acid levels with the risk of musculoskeletal disorders among dentists at Public Health Centers in Surabaya. Method: This research was an analytical observational research using cross sectional approach. Sampling technique used in this research was cluster random sampling with nineteen samples. To evaluate the working positions of those samples, a rapid entire body assessment (REBA) method was used. Meanwhile, to observe the musculoskeletal disorders of those samples, a Nordic body map was used. Data obtained then were analyzed using Pearson correlation test with a significance level (p<0.05). Result: Results of data analysis using the Pearson correlation test showed that the significance value obtained was 0.036. It indicates that there was a correlation between the working positions and the lactic acid levels with the musculoskeletal disorders in those dentists. The results of the Pearson correlation test also revealed that there was a correlation between the working positions and the lactic acid levels among those dentists with a significance value of 0.025. Conclusion: It may be concluded that the wrong body positions during working can increase lactic acid level in the body of dentists. The increased level of lactic acid then can affect their muscles, leading to the high risk of musculoskeletal disorders.

Abstract

Background: Oral candidiasis is the mostly found oral manifestation in HIV/AIDS infected patient caused by immunocompromised especially immunodeficiency. Clinical symptoms is severe pain in oral cavity and dry mouth because of xerostomia which cause the loss of appetite. Candida albicans (C. albicans) is normal flora in oral cavity which plays as opportunistic pathogen and also the cause of oral candidiasis. Almost 90% of HIV–infected patient have oral candidiasis. This condition is clinical problem which has not been well-managed yet. C. albicans colonized oral mucous cavity has different genetic variability for each strain. Phenotype of C. albicans has been determined by genetic factor and environtment. This condition stimulate differences of genotype among various strain of C. albicans in the world. Purpose: The purpose of this research is to analyze the genetic variability of C.albicans which colonized in the mucous oral cavity of HIV/AIDS patient in Surabaya in the treatment with and without ARV therapy and non HIV/AIDS. Methods: This research has been identify and characterize the prevalent strain of C. albicans isolat in Surabaya (East Java) in HIV/AIDS infected patient with oral candidiasis by method of Iatron candidal check. The highlight of this research including cytology examination by Papanicoloau staining, C. albicans culture, spheroplast making, DNA isolation and genetic variability checking by randomly amplyfied polymorphism DNA (RAPD). Results: C. albicans colonizing oral mucosa of non-HIV patients had a predisposition of farther genetic relationship (genetic distance of 0.452) with C. albicans colonizing oral mucosa of HIV ARV and HIV non-ARV patients. The genetic distance was ranging between 0 and 1, where 9 was long genetic distance and 1 was short genetic distance. In contrast, C. albicans colonizing oral mucosa of HIV ARV have predisposition of closer genetic relationship (genetic distance of 0.762) with C. albicans colonizing oral mucosa of HIV non-ARV patients. Conclusion: The conclusion of this research were C.albicans colonizing HIV/AIDS patiens with and without ARV showed no high genetic variability between C.albicans isolate in HIV patients. There fore, the character of C.albicans colonizing HIV ARV and HIV non-ARV patients had similar genotype predisposition of closer relationship value with C.albicans colonizing oral mucosa non HIV patients.Latar belakang: Oral candidiasis merupakan manifestasi kelainan rongga mulut yang paling sering timbul pada penderita HIV/AIDS karena kondisi immunocompromised terutama defisiensi imun. Gejala klinisnya berupa nyeri hebat di rongga mulut dan mulut kering karena xerostomia yang menyebabkan hilangnya nafsu makan. Candida albicans (C. albicans) berperan sebagai patogen oprtunistik dan merupakan penyebab Kandidiasis rongga mulut. Hampir 90% penderita terinfeksi HIV mengalami kandidiasis rongga mulut. Kondisi ini merupakan masalah klinis yang belum teratasi dengan baik. Kolonisasi C. albicans di mukosa rongga mulut mempunyai variabilitas genetic yang berbeda untuk tiap strainnya. Fenotip C. albicans ditentukan oleh faktor genetic dan lingkungan. Kondisi ini menstimulir perbedaan genotip di antara berbagai strain C. albicans di dunia. Tujuan: Tujuan penelitian ini adalah meneliti korelasi antara hubungan genetik yang menunjukkan variasi genetik kolonisasi C. albicans pada rongga mulut dan insidens kandidiasis rongga mulut pada penderita HIV/AIDS dan non-HIV/AIDS. Metode: Penelitian ini mengidentifikasi dan mengkarakterisasi strain Candida albicans isolat Surabaya (Jawa Timur) pada penderita HIV/AIDS dengan kandidiasis rongga mulut dengan metode iatron candidal check. Penekanan dalam penelitian ini termasuk pada pemeriksaan sitologi dengan pengecatan Papanicoloau, kultur C. albicans, pembuatan spheroplast, isolasi DNA dan pemeriksaan variabilitas genetik dengan randomly amplified polymorphism DNA (RAPD). Hasil: C. albicans yang berkolonisasi di rongga mulut pada penderita non-HIV mempunyai predisposisi hubungan genetik (jarak genetik 0.452) dengan C. albicans yang berkolonisasi di rongga mulut pada penderita HIV yang mendapatkan terapi ARV dan non ARV. Jarak genetic bervariasi antara 0 dan 1, dimana 9 dalah jarak genetik terpanjang and 1 adalah jarak genetik terpendek. Sebaliknya, C. albicans yang berkolonisasi di rongga mulut pada penderita HIV yang menerima terapi ARV memiliki predisposisi hubungan genetic yang lebih dekat (jarak genetic 0.762) dibandingkan C. albicans yang berkolonisasi di rongga mulut pada penderita HIV non-ARV. Kesimpulan: Sebagai kesimpulan, penelitian ini menunjukkan bahwa C. albicans isolate Surabaya yang mengkolonisasi penderita HIV/AIDS dengan ARV dan non ARV memiliki hubungan kekerabatan genetik yang sama dibanding dengan pasien non HIV/AIDS.

Abstract

The goal of endodontic treatment is to keep the teeth as long as possible in the mouth. The obturation process in the root canal is one of the most important processes in endodontic treatment. The purpose of this article is to explain that overfilling is an influencing factor to the success of endodontic treatment. It has been widely known that overfilling should be avoided during an obturation process. Overfilling of the root canal is indicated only in cases which will be followed by apicoectomy, when the foreign material is removed. Accidental overfilling may occur with soft material (for example, certain pastes and cements) or with solid material (such as gutta-percha or silver cones). Such overfilling may cause an unnecessary mechanical and chemical irritation, which hinders the repair of periapical tissue, and thus, diminishes the probability of a successful endodontic treatment prognosis. Many things could cause overfilling, which makes overfilling unpleasant feeling for the patient such as severe pain, periapical lesion, gingival discoloration, periodontal ligament breakage, or even paresthesia. There are several ways to overcome this root canal overfilling, from the conventional endodontic treatment up to endodontic surgery. The main conclusion from this article is to avoid overfilling and the importance of clinicians’ compliance to the right procedures.

Abstract

Dental implants have been used for several decades. Patients of all ages have chosen dental implants to replace a single tooth or several teeth or to support partial or full dentures. This paper reports two cases of patients treated with dental implant as alternative to replace the missing teeth and connected with natural tooth as abutments in a fixed restoration with distal cantilever bridge. The underlining reasons that we decided to make such kind fixed prostheses are because of clinically imposible to put the implant on certain area and the patients asked for prostheses as optimum as possible, so the mastication function could return to the homeostasis condition. The benefit of these treatments are that prostheses could be made as optimum as possible with a more economic price, so the patients feel quite satisfied. The result shows that a few years after the treatments finished there is no any disadvantageous effect of connecting teeth to implants as abutments in fixed partial dentures and there is no sign of a harmful effect to the opposing teeth either.

Abstract

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.

Abstract

Background: Periodontal disease is caused by periodontopatogen bacteria resulting the alveolar bone damage. The decrease of osteoblasts and the increased of osteoclasts can cause bone destruction. The decrease of osteoblasts, due to a disturbance of differentiation, proliferation and apoptosis. Inflammatory mediators are prostaglandin E2 (PGE2), interleukin-1 (IL-1), IL-6 also tumor necrosis alpha (TNF-α) stimulates osteoblast apoptosis through gene expression, signaling molecules and receptor-forming osteoblasts. Fish oil of Lemuru, which is widely encountered in Indonesian coast, containing n-3 poly unsaturated fatty acids (n-3 PUFAs) are quite high. Consumption of fish oil shown to reduce the expression of PGE2, IL-1, IL-6 and TNF-α. Purpose: The purpose of this study was to examine the effect of Lemuru (Sardinella longicep) fish oil on osteoblast apoptosis of rat alveolar bone induced periodontal infection. Methods: Thirty Wistar rats, male, age 5 days, divided into 3 groups: group I rats induced with normal saline, group II rats induced by LPS, and group III rats induced with lemuru fish oil and LPS. Each group was divided into 2 sub-groups that would be sacrified at 13 days and 21 days of age. Fish oil was given at a dose 1ml/300-350 grams. Lipopolysaccharide (LPS) induced with the purpose to cause periodontal infection in the maxillary buccal fold molar region with dose 5μl LPS/PBS 0.03 ml. After decapitation and decalcification, the maxilla was cut in 5μm thickness. Apoptosis was analyzed on DNA and detected by TUNEL reaction (transferase-mediated digoxigenin-deoxy-UTP nick end labeling). Results: The results showed that apoptosis of osteoblast cells was significantly smaller in rats induced by Lemuru fish oil. Conclusion: The study showed that Lemuru fish oil reduced the osteoblast apoptosis of rats alveolar bone induced periodontal infection by LPS.Latar belakang: Penyakit periodontal akibat bakteri peridontopatogen, menyebabkan terjadinya kerusakan tulang alveolar. Penurunan jumlah osteoblas dan peningkatan jumlah osteoklas mengakibatkan kerusakan tulang. Penurunan jumlah osteoblas disebabkan terjadinya gangguan diferensiasi maupun proliferasi juga apoptosis. Apoptosis osteoblas dimodulasi oleh mediator-mediator inflamatori yaitu prostaglandin E2 (PGE2), interleukin-1 (IL-1), IL-6 juga tumor nekrosis alfa (TNF-α), melalui pengaruhnya pada ekspresi gen, molekul-molekul signaling maupun reseptor pembentukan osteoblas. Minyak ikan Lemuru yang banyak di pesisir Indonesia, banyak mengandung n-3 poly unsaturated fatty acid (n-3 PUFA). Konsumsi minyak ikan terbukti menurunkan ekspresi PGE2, IL-1, IL-6 maupun TNF alfa. Tujuan: Tujuan penelitian ini adalah untuk meneliti pengaruh minyak ikan Lemuru (Sardinella longicep) pada apoptosis osteoblas pada tulang alveolar tikus yang diinduksi infeksi periodontal. Metode: Tiga puluh ekor tikus Wistar, jantan, umur 5 hari, dibagi menjadi 3 kelompok yaitu: kelompok I tikus diinduksi dengan salin normal, kelompok II tikus diinduksi dengan lipopolisakarida (LPS), dan kelompok III tikus dinduksi dengan minyak ikan Lemuru dan LPS. Masing-masing kelompok dibagi menjadi "> 2 sub kelompok yaitu kelompok yang akan didekapitasi pada umur 13 hari dan umur 21 hari. Minyak ikan Lemuru diberikan dengan dosis 1ml/300-350 gram. Lipopolisakarida (LPS) diinduksikan dengan tujuan untuk menyebabkan infeksi periodontal pada buccal fold regio molar rahang atas, dengan dosis 5μl LPS/0,03PBS (konsentrasi 0,02 mg). Setelah didekapitasi dan dekalsifikasi, rahang atas dipotong dengan ketebalan 5μm. Apoptosis dianalisis pada DNA dan dideteksi dengan TUNEL reaction (Transferase-mediated digoxigenin-deoxy-UTP nick end labeling). Hasil: Hasil penelitian menunjukkan bahwa apoptosis sel osteoblas secara bermakna lebih kecil pada tikus yang diinduksi dengan minyak ikan. Simpulan: Penelitian ini menunjukkan bahwa minyak ikan Lemuru (Sardinella longicep) mampu menurunkan apoptosis sel osteoblas pada tikus Wistar yang diinduksi infeksi periodontal dengan LPS.
