"Penelitian ini bertujuan untuk mengetahui pengaruh saliva buatan dengan pH yang berbeda-beda terhadap terhadap kekuatan tarik diametral Semen Ionomer Kaca Modifikasi Resin (SIKMR) yang dilapisi bahan pelindung varnish dan nanofilled coating agent. Spesimen yang dilapisi bahan pelindung direndam dalam saliva pH 4,5, 5,5, dan 7 selama 24 jam dalam inkubator bersuhu 37°C. Kekuatan tarik diametral diuji dengan Universal Testing Machine.Hasil menunjukkan perbedaan yang tidak bermakna pada seluruh spesimen yang dikelompokkan berdasarkan tingkat keasaman saliva serta jenis bahan pelindung (p>0,05). Bahan pelindung varnish maupun nanofilled coating agent dapat bertahan dengan baik pada SIKMR dalam kondisi asam yang merupakan simulasi keadaan rongga mulut pada kelompok orang dengan resiko karies tinggi selama 24 jam proses maturasinya.

The aim of this study was to evaluate the effect of artificial saliva with different acidities on the diametral tensile strength of RMGIC coated with varnish and nanofilled coating agent. The specimens coated with coating agents were immersed in artificial saliva with the pH of 4.5, 5.5, and 7 for 24 hours at 37°C. The diametral tensile strength of the specimens were tested with Universal Testing Machine.

There were no significant differences on the diametral tensile strength of all specimens that were put into groups based on the acidity of the saliva and the type of coating agent (p>0.05). Both varnish and nanofilled coating agent stayed on the RMGIC in the acidic condition that simulated the true condition of oral cavity of people with high caries risk for the 24 hours of maturation."

"Penelitian ini bertujuan untuk menganalisis pengaruh pH saliva terhadap kekuatan tarik diametral semen ionomer kaca (SIK) yang dilapisi coating agent. Spesimen SIK yang telah dilapisi varnish dan nanofilled coating agent direndam dalam saliva buatan pH 4,5 5,5 dan 7 selama 24 jam pada suhu 37ºC, kemudian dilakukan pengujian kekuatan tarik diametral dengan Universal Testing Machine.Hasil menunjukkan bahwa tidak terdapat perbedaan bermakna nilai kekuatan tarik diametral SIK yang dilapisi varnish maupun nanofilled coating agent dengan menurunnya pH saliva (p<0,05).Disimpulkan bahwa pH saliva tidak mempengaruhi kekuatan tarik diametral SIK yang dilapisi varnish maupun nanofilled coating agent.

The aim of this study was to analyze the effect of salivary pH to diametral tensile strength of Glass Ionomer Cement (GIC) coated by coating agent. GIC specimens coated by varnish and nanofilled coating agent were stored in artificial saliva pH 4,5 5,5 and 7 for 24 hours at 37ºC, then diametral tensile strength was tested by Universal Testing Machine.

Result showed that there was no significant different in diametral tensile strength of GIC coated by varnish and nanofilled coating agent with decreasing of salivary pH (p<0,05).

It can be concluded that salivary pH does not affect the diametral tensile strength of GIC coated by varnish or nanofilled coating agent."

"Phleomorphic adenoma is the most commonly found tumor of the salivary glands. This tumor is usually found in the postero-lateral region of the hard palate. In this case, a phleomorphic adenoma tumor situated in the oropharynx region was reported. The CT-Scan results showed an expansive and infiltrative appearance, suspected to be a malignancy, where wide excision was previously planned to be carried out. During surgery, the mass was found pedunculated in the soft palate. It was then decided to perform an excision as the choice of therapy."

"ABSTRACTAdenoid cystic carcinoma (ACC) is one of the common malignant tumors in salivary glands, and the clinical prognosis is poor with frequent distant metastasis which may lead to death. Expression of the MYB-NFIB chimeric gene in ACC has been reported recently. MYB is an oncogene with transcription regulating functions, and NFIB encodes nuclear transcription factor although detailed functions are unknown. This study investigated whether MYB-NFIB chimeric gene expression affects tumor angiogenesis and proliferation in salivary gland ACC. In 26 salivary gland ACC cases, MYB-NFIB chimeric gene expression was analyzed by RT-PCR and direct sequencing. Immunohistochemical studies for CD31, vascular endothelial growth factor (VEGF) and Ki-67 were performed. Tumor angiogenesis was evaluated by blood vessel (CD31-positive) density and tumor proliferation by Ki-67 labeling index, and the relationship with MYB-NFIB chimeric gene expression was analyzed. MYB-NFIB chimeric gene expression was detected in nine of 26 ACC cases. Blood vessel density was significantly higher in chimeric gene-expressing cases compared to non-expressing cases. VEGF score tended to be higher in chimeric gene-expressing cases than in non-expressing cases, while Ki-67 labeling index was not significantly different. The number of chimeric gene-expressing cases increased with age, peaking in the sixties age group and declining thereafter, while the number of non-expressing cases increased with age continuously. In ACC, blood vessel density was significantly higher in MYB-NFIB chimeric gene-expressing cases compared to non-expressing cases, which may be due to higher VEGF production capability. MYB-NFIB chimeric gene expression may also be related to the onset age of ACC."
