The purpose of this study was to analyze the level of patient satisfaction after orthognathic surgery and the correlation between the patient satisfaction level after orthognathic surgery and the results of the cephalometric skeletal analysis.<strong> </strong><strong>Met</strong><strong>hods: </strong>This research is analytic observational research. The subjects of this study were patients who had orthognathic surgery either BSSO, Osteotomy Le Fort 1, or Double Jaw Surgery. First, the subjects filled out a questionnaire about patient satisfaction after orthognathic surgery, the second was taking cephalometric radiographs which were then analyzed by the Steiner method by measuring the angles of SNA, SNB, ANB, and GoGN-SN. The subjects of this study were taken from patients who had undergone orthognathic surgery at the Oral and Maxillofacial Surgery Department of Hasan Sadikin Hospital (RSHS) and the Dental Hospital of Padjadjaran University (RSGM Unpad) Bandung in 2015-2020. The number of samples in this study was 10 people. The research was conducted from February 2020 to July 2020. The results of the questionnaire obtained as research data were scored and grouped into 3 groups, namely dissatisfied, satisfied, and very satisfied. Furthermore, the research data in the form of cephalometric analysis results were categorized into normal and abnormal. The two research data were then tested for their correlation using the Concordal Kendall correlation test, with a confidence level of 95% and alpha 5% using Excel MegaStat software.<strong> Results: </strong>The results of the study on 10 research subjects showed that all questionnaire scores were in the "satisfied" category. Cephalometric skeletal analysis of all cephalograms showed 50% normal SNA angle, 10% normal SNB angle, 80% normal ANB angle, and 90% normal GoGN-SN angle. The Concordal Kendall test results show the correlation coefficient value of 0.534 or 53.4%. The positive correlation coefficient shows a unidirectional relationship between the level of patient satisfaction after orthognathic surgery and the results of cephalometric skeletal analysis, meaning that the better the skeletal cephalometric analysis value, the higher the level of patient satisfaction. <strong>Conclusions: </strong>On average, patients are very satisfied with the orthognathic surgery they have undergone. There is a correlation between the level of patient satisfaction after orthognathic surgery and the results of the cephalometric skeletal analysis.</p> Joni Putra, Endang Sjamsudin, Asri Arumsari, Abel T.

Beluntas leaves (Pluchea indica l.) contain antibacterial active substances that can be used as a preventive measure against the growth of these microorganisms. Beluntas leaf extract contains flavonoids, tannins, terpenoids of various essential oils and phenols which act as inhibitory agents, induce bacteriolysis and ultimately death. The purpose of this study was to determine the exact values of MBC (Minimum Bactericidal Concentration) and MIC (Minimum Inhibitory Concentration) of beluntas leaf extract against Streptococcus mutans colonies.</p><p><strong>Material and Methood:</strong> Measurement of MBC (Minimum Bactericidal Concentration) and MIC (Minimum Inhibitory Concentration) values of beluntas leaf extract against Streptococcus mutans colonies was carried out by determining the number of bacterial colonies after administration of the extract. This study used Streptococcus mutans ATCC 25175 and ethanol extract of beluntas leaves with concentrations: 250 g/ml, 125 g/ml, 62.5 g/ml, 31.3 g/ml, 15.6 g/ml, 7.8 g /ml, 3.9 g/ml and 1.95?g/ml. This study used two methods, Broth Microdilution and Total Plate Count techniques as the designated method for the purpose of counting bacteria. Furthermore, the data analysis test was carried out to analyze normality using the Kolmogorov-Smirnov test. If the data distribution shows normal, then one way ANOVA parametric test is performed to determine the significance between the beluntas leaf extract and the number of Streptococcus mutans bacteria, which will then be further examined using the Post-Hoc Test with the Tuckey method to find out which dataset is the most significantly different in among others.</p><p><strong>Results:</strong> The results showed that the beluntas leaf extract showed significant bacterial properties against Streptococcus mutans (P-Value = 0.00) which was expressed through definite MBC and MIC values. The results showed that the MIC and MBC values were 62.5 g/ml and 125 g/ml, respectively against Streptococcus mutans colonies.</p><p><strong>Conclusions:</strong> The conclusion of this study was that the ethanol extract of the leaves of beluntas (Pluchea Indica L) showed antibacterial properties as indicated by the MIC value at a concentration of 62.5?g/ml and the MBC at a concentration of 125?g/ml against Streptococcus mutans.<strong></strong></p> Elin Septiani, Natallia Pranata, Vinna K.

On extraoral examination, the face was bilaterally asymmetrical. An ultrasonography revealed hypoechoic mass of size 1.5x2.5x2.5 cm on left parotid gland. Computed tomography (CT) revealed a slight irregular mass on left parotid gland with no infiltration to adjacent tissues. Based on these findings, a clinical diagnosis of left parotid benign tumor was made.</p> <p style="font-weight: 400;"><strong>Results:</strong> A surgical excision was performed under general anesthesia. On histopathological examination, the connective tissue was rich in fibrous components and was accompanied by hyaline. Epithelial cells with high atypia proliferating invasively as cords into connective tissue were observed. The intraductal component had Roman-bridge-like architecture with central portion undergoing comedonecrosis. Based on these findings, a final diagnosis of salivary duct carcinoma possibly arising from pleomorphic adenoma was made. p16 hypermethylation is a known phenomenon in oral malignancy. We also checked the methylation status of p16 gene and found high level of methylation in this tumor.</p> <p style="font-weight: 400;"><strong>Conclusion: </strong>We reported a rare case of salivary duct carcinoma possibly arising from pleomorphic adenoma and also demonstrated high methylation level of p16 gene in the tumor.</p> Dedy Ariwansa, Durga Paudel, Tetsuro Morikawa, Koki Yoshida, Ariuntsetseg Khurelchuluun, Shuhei Takahashi, Jun Sato, Eiji Nakayama, Hiroki Nagayasu, Yoshihiro Akbiko Copyright (c) 2022 Dedy Ariwansa, Durga Paudel, Tetsuro Morikawa, Koki Yoshida, Ariuntsetseg Khurelchuluun, Shuhei Takahashi, Jun Sato, Eiji Nakayama, Hiroki Nagayasu, Yoshihiro Akbiko https://creativecommons.org/licenses/by/4.0 https://jdmfs.org/index.php/jdmfs/article/view/1348 Mon, 01 Aug 2022 00:00:00 +0000 Removal of an Ectopic Canine Tooth in the Maxillary Sinus Using Bone Lid Technique https://jdmfs.org/index.php/jdmfs/article/view/992 <p><strong>Abstract</strong></p><p><strong>Objective:</strong> Ectopic teeth are teeth that are located deep in the jawbone or in other areas outside the alveolar bone, such as nasal cavity, chin, mandibular bone, palate, orbital cavity, and maxillary sinus. The presence of teeth in the maxillary sinus can cause an inflammatory reaction in the sinus and cause local sinonasal symptoms such as nasal obstruction, facial fullness, headache, hyposmia, and recurrent chronic sinusitis, due to obstruction of the sinus ostium and it can also develop into cysts. Replantation of bone fragments after tooth extraction using the Bone Lid technique can maintain sinus volume. The aim of this paper is to report the extraction of ectopic teeth in the maxillary sinus by using Bone Lid technique.</p><p><strong>Methods:</strong> A 9-year-old girl was referred from ENT clinic with complaints of pain in the right cheek and sniffles which were diagnosed as maxillary sinusitis. Radiographic examination showed that the canine tooth was located on the right maxillary sinus. The ectopic canine tooth was removed with a modified bone lid technique.</p><p><strong>Result:</strong> The panoramic radiograph and Waters’ projection radiograph postoperatively showed there were no ectopic teeth in the sinus and no volumetric changes of maxillary sinus cavity. In the clinical evaluation of 1 month postoperatively, there were no complaints of pain and sniffles.</p><strong>Conclusion: </strong>The use of the Bone Lid technique is beneficial because it maintains sinus volume, thus it does not disturb the function of the maxillary sinus.
