The application of methacrylate resin and the derivation (composite resin and dentin bonding) in clinical conservative dentistry has been widely developed. This material could be used to restore class I-V cavity with good aesthetic due to the compatible color with tooth. Composite resin adhesion hydrophobically in enamel that is due to mechanic retention in the form of resin tags which penetrates into enamel porosity. Meanwhile hydrophilic dentin bonding adhesion due to the chemical reaction between functional groups of amino collagen with carbonyl in dentin bonding forming amide binding. In addition mechanical retention in which dentin bonding penetrating into nano inter fibrilar cavity then polymerized. The success of methacrylate resin adhesion restoration is decided by enamel porosity, wetting character of resin, wetting contact angle, good etching acid, optimal humidity of tooth surface, the accuracy of dentist during filling is done etc.

Background: Infectious mononucleosis (IM) is the self limiting disease that associated with primary Epstein Barr virus (EBV). It is a gamma herpes virus. EBV infection is follows saliva-transfer by kissing or sexual intercourse. The most clinical manifestation in IM consists mainly of the specific sign: pharyngitis, fever, and lymphadenopathy. The main therapy is supportive treatment. Actually the antiviral therapy is required for the host with high response immune. Purpose: The aimed of this study was to report the therapy of IM using methisoprinol. Case: The woman patient, 33 years old, came to hospital by suffering pharyngitis and swolen on left neck. It had been since 3 days ago. Case management: She had come to Puskesmas that were given amoxycillin capsul 500 mg three times a day for three days and paracetamol tablet 500mg three times a day for three days, but she was still ill. Then she came to RSGM Hasan Aman Banjarmasin. She was diagnosed as IM. The instruction were isolation and bed rest for a week. She had to eat sofly and drink water highly. The therapy were amoxycillin capsul 500 mg three times a day for seven days, methisoprinol caplet 500 mg three times a day for seven days, natrium dikofenak tablet 50 mg three times a day for seven days. She was asked to see the dentist next 7 days. In this case, she were not given acyclovir. Conclusion: IM is self limiting disease. IM is the disease with spesific clinical syndrome that associated with primary EBV infection. Depend on the base of clinical experiences, the supportive treatment is adviced for patient of IM. Methisoprinol has both immunomodulator and antiviral properties.

Oral candidiasis is one of the most common opportunistic infections in HIV/AIDS patients. It serves as important markers of HIV infection, viral load, and CD4 cells count in the blood and predict disease progression to AIDS. The development of oral candidiasis in HIV/AIDS patients associated by imbalances between Candida and impaired host immune defenses that caused by decreased of CD4 cell counts and the increased of plasma HIV-viral load. Since the introduction of antiretroviral therapy combination, commonly known as Highly Active Antiretroviral Therapy (HAART), it has been observed that certain oral lesions, such as oral candidiasis as declined. The aim of this paper is to review the mechanism of combination antiretroviral therapy influenced the frequency of oral candidiasis in HIV/AIDS patient. We conclude that combination antiretroviral therapy generally reduced the frequency and severity of oral candidiasis in HIV/AIDS patient.

Background: Mandibular bone on panoramic radiographs has been proven to be useful for identifying postmenopausal women with low skeletal bone mineral density. One of the important parts of mandibular bone is trabecular bone. Trabecular bone architecture is one of the factors that governs bone strength and may be categorized as a contributor to bone quality. Purpose: The purposes of this study were to develop a computer-aided system for measuring trabecular bone line strength on panoramic radiographs in identifying postmenopausal women with osteoporosis and to clarify the diagnostic efficacy of the system. Methods: Reduction and expansion of trabecular bone sample images using a two level Gaussian pyramid for removing noises and small segments were first introduced. Then, line strength at each pixel was calculated based on its existence on the trabecular bone with emphasizes line segment which has similar orientation with the root of tooth. The density was measured with respect to line strength of segment structure which has similar orientation with the root of tooth, either on the left and the right in the mandibular bone. Number of pixels in the line segment area was compared with a threshold value to determine whether normal or osteoporosis. Results: From experiment on 100 data, the accuracy of 88%, sensitivity of 92%, and specificity of 86.7% were achieved. Conclusion: The computer-aided system of trabecular bone analysis may be useful for detecting osteoporosis using panoramic radiographs.Latar belakang: Tulang mandibula pada panoramik radiografi telah banyak diteliti dan terbukti mampu digunakan untuk mengidentifikasi wanita pasca menopause dengan menggunakan bone mineral density rendah. Salah satu bagian tulang mandibula yang penting adalah tulang trabekula. Arsitektur tulang trabekula merupakan salah satu dari faktor-faktor yang mempengaruhi kekuatan tulang dan dapat digolongkan sebagai kontributor bagi kualitas tulang. Tujuan: Penelitian ini bertujuan untuk membangun sebuah sistem dengan bantuan komputer untuk mengukur kekuatan garis pada tulang trabekula dan menggunakannya untuk mendeteksi osteoporosis pada wanita postmenopause. Metode: Dilakukan sampling pada sebagian tulang mandibular yang menghasilkan sebuah sampel citra. Sampel citra ini selanjutnya diperbaiki dari derau (noise) dengan menggunakan piramida Gaussian dua level. Kekuatan garis pada tiap piksel dihitung berdasarkan orientasi segmen garis tulang trabekula yang sejajar dengan akar gigi. Setelah dilakukan binerisasi, luasan segmen yang dihasilkan dihitung dan dibandingkan dengan sebuah nilai ambang. Bila luasan melebihi nilai threshold maka dikategorikan sebagai normal. Sebaliknya bila luasan dibawah nilai threshold, dikategorikan sebagai osteoporosis. Hasil: Berdasarkan eksperimen terhadap 100 data, sistem mampu mencapai akurasi identifikasi sebesar 88%, sensitivitas 92%, dan spesifisitas 86,7%. Kesimpulan: Sistem analisa trabecular bone dengan bantuan komputer ini dapat digunakan oleh para dokter gigi untuk mendeteksi osteoporosis menggunakan panoramik radiografi.

Secretory Leukocyte Protease Inhibitor (SLPI) is serine protease inhibitor. Secretory Leukocyte Protease Inhibitor is a protein found in secretions such as whole saliva, seminal fluid, cervical mucus, synovial fluid, breast milk, tears, and cerebral spinal fluid, as in secretions from the nose and bronchi, amniotic fluid and amniotic membrane etc. These findings demonstrate that SLPI function as a potent anti protease, anti inflammatory, bactericidal, antifungal, tissue repair, extra cellular synthesis. Impaired healing states are characterized by excessive proteolysis and often bacterial infection, leading to the hypothesis that SLPI may have a role in the process. The objectives of this article are to investigate the role of SLPI in oral inflammation and how it contributes to tissue repair in oral mucosa. The oral wound healing responses are impaired in the SLPI sufficient mice and matrix synthesis and collagen deposition are delayed. This study indicated that SLPI is a povital factor necessary for optimal wound healing.

Sinusitis is a frequent complication of allergic rhinitis. Theoretically, sinusitis could be found in human since infancy. The prevalence of diagnosed sinusitis is 20% of ambulatory patients in daily practice. Unfortunately, a lot of sinusitis cases must be treated by surgical operation. Other cases are treated conservatively with decongestants, corticosteroids, antibiotics and diathermy. However, dental treatment approach for sinusitis management is rarely discussed. Headache, especially migraine is also a common problem in children. Sinusitis and migraine, are closely related; sinusitis sufferers often accompanied by migraine and vice versa. This phenomenon resulting in misdiagnosis of the main etiology of sinusitis and migraine; if this case happens in young children, the diagnosis should be more complicated. Dental procedures which may directly reduce the periodontal inflammation were done to children diagnosed as sinusitis by otolaryngologist and pediatrician. In a short period of time, the sinusitis and headache symptoms subsided. The objective of this case reports is to propose the possible explanation of the neurogenic switching mechanism cut off, that resulting in the instant relief of sinusitis and headache symptoms. Regarding the immediate relief of the symptoms, the role of autonomic nervous system should also be considered. Since parasympathetic innervations of nasal, sinus mucosa and maxillary periodontal tissues originated from the sphenopalatine ganglion; the conclusion is that the periodontal inflammation may sensitize the sphenopalatine ganglion which may trigger sinusitis and headache in children.

Background: Recurrent aphthous stomatitis (RAS) are painful oral ulcerations that recur from days to months or even years. It represents the most common lesion of the oral mucosa with prevalence ranging from 15% to 30%. Although the clinical characteristics of RAS are well defined, the precise etiopathogenesis of RAS remains unclear. Since the etiology of RAS remains unknown, there is no definitive treatment. RAS responds quite well to the use of topical or systemic antiinflammatory drugs, particularly corticosteroids. Purpose: The objective of this paper is to discuss the treatment of RAS with secondary infection. Case: This paper reported a case of 22-year-old man with multiple oral ulcers that did not heal for 7 months. Case Management: These ulcers were diagnosed as RAS major with secondary infection that caused by normal oral flora (aerobic and anaerobic bacteria) and treated with metronidazole (topical and oral) and ciprofloxacin (oral). These lesions healed in 3 weeks with scars. Conclusion: Large ulcer without signs of malignancy that contaminated with normal oral flora will delayed in healing, but with rational treatment RAS mayor with secondary infection has good prognosis.

Long-face cases usually need both treatment of orthodontic and surgery. The problem appearing in the correction of long-face might be able to be related with some difficult factors such as the crowded teeth and excessive vertical height. A class III malocclusion and excessive open bite can be also followed in long face. This situation might worsen the facial aesthetic condition and increase the difficulty in orthodontic treatment. The orthodontic approach is oriented toward positioning the teeth pre-surgically to facilitate the surgical plan. The form of mandible which has grown in the downward direction in the area of mandible angle makes an extreme vertical open bite. The maxilla is usually presented with a maxillary hypolasia. Double-jaw surgery was done as the correction of the lower jaw alone would produce a flattened face appearance and difficulty in repositioning the mandible to achieve a good facial performance. Several cephalometric points were measured to observe the facial situation progress after surgery. Two cases of longface are reported, and the same surgical treatments were performed and showed different results.

Background: Pulp inflammation can be marked by the increase of prostaglandin E2(PGE2) level compared to normal pulp. The increase of PGE2 may lead to vasodilatation, increase of vascular permeability, pain and bone resorption. Watermelon frost has been well known in Chinese society for pain relief and inflammation in oral cavity and teeth. Purpose: The aim of this study was to investigate that watermelon frost can be used to decrease the PGE2 level. Method: 27 samples of pulp tissues used in this in-vitro study, were extirpated from the patients’ teeth with symptomatic irreversible pulpitis referred to clinic of Conservative Dentistry, RSPGM Faculty of Dentistry, USU. Trial materials were applied to 27 samples i.e. watermelon frost as a trial material and commercial watermelon frost and eugenol to observe their effect on PGE2. PGE2 level of each material was detected through ELISA method by measuring and comparing the absorbance reading of the wells of the samples against standards with a micro plate reader at W1 = 650 nm and W2 = 490 nm. Result: The result showed the biggest effect was found in the third group (eugenol), mean 4.6933, followed by the first group (watermelon frost as a trial material), mean 18,1578 then the second group (commercial watermelon frost), mean 82,2689. OneWay ANOVA revealed that there were significant differences among all trial materials (p < 0.001) on PGE2 level. Conclusion: This study demonstrated that watermelon frost can be used to decrease the PGE2 level in inflamed pulp tissue and led to the acceptance of traditional medicine and natural products as an alternative form of dental care.
