<![CDATA[Background: One of the artifacts found on the CT scan is a metal artifact. Metal artifacts are caused by metal objects present in patients' bodies. The file of metal artifacts can cover the organ that will be evaluated, and it can be inferred with the pixel value (CT number) assessment of the tissue around the metal. Purpose: To determine the effect of the band pass median filter and find the optimal filter to reduce metal artifacts on the head CT scan. Method: A total of 43 samples of patients's files from head CT-scan without any contrast were reconstructed using four band pass median filters and obtained R1, R2, R5, and R10 filters. Two radiology specialists were assessed for the reduction of metal artifacts using the ImageJ application. Result: Four variations of the filter affected the reduction of metal artifacts because the band pass median filter maintained a point that was close to its neighboring points and points that were different from its neighboring points by replacing the value of the pixel with the median value of the grey level of neighboring pixels. The optimal filter recommendation is the R1 filter because it has the largest SNR value (16.9773) and the smallest RMSE value (8.57501) so that the result of the image is more informative and has a diagnostic value. Conclusion: The four filter variations were affected by reducing metal artifacts. Images with substantial SNR and fractional RMSE values produced an image that was more informative and still had diagnostic value.]]>

<![CDATA[Background: Routine pelvic radiograph examination commonly performed in diagnostic radiology services is a pelvic examination of anteroposterior projection (AP). This results in direct exposure to ionizing radiation to the internal organs in the lower abdomen, especially the reproductive organs. Purpose: Optimizing the dosage of AP projection pelvic radiographs. Method: Research is conducted quantitatively and used experimental approach with an analysis of 15% mAs reduction from the standard mAs value on AP projection pelvic examination on radiation dose and image quality using anthropomorphic phantoms. The radiation dose analysis uses the exposure index indicator. In contrast, the image quality uses the Visual Grading Analysis method, then it was continued with the Kappa Cohens test to determine the level of agreement between 2 respondents. Result: The exposure factor with the mAs value reduced by 15% from the standard exposure factor on the AP projection pelvic radiography affected the decrease in the value exposure index. The EI value generated from the optimization exposure factor shows a decrease to 300 EI, which means the dose produced is only half of the standard exposure factor dose but still produces an acceptable image, as evidenced by the VGA score. As an assessment of image quality. In this study, there was no significant difference with range VGA scores 1,7. Besides that, the test had the Kappa Cohens level of agreement with a value of 0.5-0.8. Conclusion: All images resulting from the 15% mAs value reduction variation can be used as a diagnostic assessment.]]>

<![CDATA[Background: Nutrition is a significant risk factor for the incidence of periodontal disease. Nutrients acting on the human genome, either directly or indirectly, can change the expression and structure of genes. One of the micronutrients associated with periodontitis is vitamin D. Vitamin D has an important role in bone and calcium metabolism and regulates serum calcium and phosphate concentrations at normal limits. Purpose: To discuss the nutritional vitamin D as an essential micronutrient in preventing and accelerating healing in periodontitis. Review: Searched two databases from article publication to April 2021, resulting in a total of 66 hits, from which seven relevant articles were selected. VDR signaling can build transcription of genes encoding proactive cytokines, bypassing the cyclo-oxygenase-2 (COX-2) and prostaglandin pathway, and can inhibit matrix metalloproteinase production. The protective mechanism of vitamin D against periodontitis occurs through two biological pathways, namely anti-microbial and anti-inflammatory pathways. The anti-microbial effect of vitamin D results from the binding of 1,25(OH)2D3 with VDR which then induces cAMP, b-def-2 and b-def-3 peptides by macrophages, monocytes, gingival epithelium and periodontal ligament epithelium. The anti-inflammatory effect occurs through decreased production of proinflammatory cytokines. Conclusion: All the signaling effects of VDR can reduce bacteria induced in the inflammatory cytokines so that personalized vitamin D supplementation with an adjusted dose as needed can be used in preventing periodontitis or accelerating the healing of periodontitis.]]>

<![CDATA[Background: Noise is a problem affecting toothache patients psychological and physical aspects. The dental clinic can be a source of noise because it contrasts with the function of the dental clinic as a place of healing. Noise can cause toothache to be more psychologically painful, which causes dryness of the oral cavity. Purpose: Therefore, it is necessary to know how much the noise level in the dental clinic is with the case study of the Benowo dental clinic and where it comes from. Method: The researchers used an explorative method and observations to realize this activity. This study begins by calculating the clinical noise level using a sound meter, and then the results are compared with a literature study. Result: The highest noise recorded in this clinic reaches 84 dB. This is very far from the sound level recommended by SNI 03-6386-2000, which is 45 dB for dental clinics. Outside noise comes from roads, trains, and parking areas. The nature of noise from outside is sporadic, but the intensity of the noise is very high. Sources of noise from inside come from activities in the medicine room, patient conversations, drills, scaling, and compressors. Noise from within is continuous but less intense. Conclusion: The design of the dental clinic must consider the acoustic aspect as the central aspect. Further research is needed to choose the right design concept to protect the dental clinic from noise.]]>

<![CDATA[Background: Certain cases such as anterior cross bites require a different aesthetic removable denture technique from the conventional removable denture. Purpose: To provide an overview of a case about the technique of making aesthetic acrylic resin removable partial dentures for anterior tooth replacement in cases of anterior cross bite. Case analysis: The study examined the working model with maxillary and mandibular anterior cross bite cases. Result: The arrangement of artificial teeth was carried out as ideally as possible, so that it became harmonious. In this case, the incisal artificial teeth 11, 12, 21 were brought forward labially, so that an edge-to-edge position was formed with the opposing teeth. The clasp made was a half jackson which was placed on teeth 15 and 25, so that when the patient smiles the clasp is not visible to fulfill the aesthetic requirements. Conclusion: The technique of making aesthetic removable partial dentures in cases of anterior cross bite that has received more attention is the arrangement of the dental elements because it is different from the normal tooth arrangement. The artificial teeth were arranged in edge-to-edge bite position in order to obtain a harmonious occlusion while taking into account of the labial arch of the adjacent tooth as well as occlusion with the opposing tooth.]]>

<![CDATA[Background: Evaluation of brain tumor MRI image results performed by radiologists employing the linear measurement method has several weaknesses and is sensitive to subjectivity. Purpose: To compare the results of measurements and calculations of brain tumors utilizing the linear measurement method on the Siemens 1.5 Tesla MRI modality employing pulse sequence spin echo with T1 contrast weighting compared with the results of measurements and calculations of brain tumors utilizing the active contour segmentation method. Method: An experimental study was conducted on 32 MRI images. Result: The study's findings indicated that the linear measurement was more significant than the active contour segmentation method (p-value<0,05). The results were obtained by calculating the sensitivity and specificity values of the diagnostic test, which were calculated to be 87.5%. Conclusion: The active contour segmentation method applied to pulse sequence spin-echo T1-weighted contrast can be utilized as an alternative measurement and calculation of brain tumors with a sensitivity and specificity value of 87.5%. Further research suggests developing a Matlab application to compare the results of measurements and calculations of brain tumors on acquiring 3D image magnetic resonance imaging data.]]>
