Abstract

Radiograf panoramik mencitrakan gigi-geligi rahang bawah dan atas beserta seluruh jaringan pendukungnya dalam sebuah citra tunggal, proses pemeriksaannya murah, cepat, dan mudah, serta paparan radiasi yang diterima oleh pasien relatif rendah. Di samping memiliki sejumlah keunggulan tersebut, radiograf panoramik juga memiliki kelemahan karena gambaran yang dihasilkan pada teknik radiografi ini mengalami distorsi geometris, sehingga hasil pencitraan pada radiografi panoramik cenderung tidak sesuai dengan ukuran struktur anatomi yang sesungguhnya pada pasien. Penelitian ini bertujuan untuk mengetahui perbedaan hasil pengukuran horizontal pada preparat mandibula dibandingkan dengan pengukuran horizontal pada citra radiograf panoramik, serta untuk mengetahui seberapa besar distorsi pengukuranhorizontal pada radiograf panoramik. Sampel penelitian berupa 56 buah preparat mandibula yang masing-masing diberi 23 buah metal marker. Radiograf panoramik diambil dari masing-masing sampel. Pengukuran horizontal pada sampel menggunakan sliding caliper digital, sedangkan pengukuran horizontal pada radiograf panoramik menggunakankomputer. Hasil penelitian menunjukkan bahwa terdapat perbedaan rerata yang bermakna (p<0,05) antara hasil pengukuran pada radiograf panoramik dibandingkan dengan hasil pengukuran pada preparat mandibula, kecuali pada hasil pengukuran horizontal regio gigi geligi posterior dan regio median line hingga posterior korpus mandibula. Hasil penelitian ini menunjukkan bahwa pada penempatan posisi kepala pasien yang memenuhi standar akan dihasilkan radiograf panoramik dengan distorsi geometris berupa penyempitan dimensi horizontal pada regio anterior mandibula. Pengukuran horizontal pada radiograf panoramik memiliki akurasi yang baik jika dilakukan pada regio posterior, namun cenderung tidak akurat jika dilakukan secara memanjang melintasi median line. Differences of Horizontal Measurement on Dry Mandibles and Panoramic Radiographs. Panoramic radiograph produces one single image of both maxillary and mandibular dental arches and their supporting structures. This technique is cheap, fast and easy, with relatively low radiation exposure received by patients. However, the panoramic radiograph also has some disadvantages related to its geometric distortion. The images of patient’s anatomical structureson panoramic radiograph are not equal with their actual dimension. The aim of this study is to determine the distortion of panoramic radiograph, by comparing the horizontal measurements on panoramic radiographs with those on the real object, which was the dry mandibles. The samples of this study were 56 dry mandibles with 23 metal markers on each ofthem. Panoramic radiograph was taken from each sample. Horizontal measurements on dry mandibles were done using digital sliding caliper, while horizontal measurements on panoramic radiograph were done using computer. The result of this study shows that there were significant differences (p<0.05) between horizontal measurements on panoramicradiographs compared with the measurements on dry mandibles, except in posterior dental arch and median line up toposterior region of mandible corpus. The results of this study indicate that panoramic radiograph taken on standardized patient’s head positioning procedure would produce geometric distortion that tends to be narrow on mandibular anterior region. The horizontal measurements of panoramic radiographs show good accuracy in posterior region, but tend to be inaccurate if done extended across the midline.

Abstract

Cone-beam computed tomography (CBCT) is an imaging modality widely used in dentistry over multi detector computed tomography (MDCT). It is in view of its high resolution with relatively lower dose. MDCT is able to show Hounsfield Unit (HU) which is proportional to x-ray attenuation degree by the tissue. The x-ray attenuation degree in CBCT is shown in grayscale value with pixel values unit. The aim of this study was to determine the correlation of pixel values in CBCT with HU in MDCT. We used secondary data from RSGM Universitas Padjajaran patient who had CBCT and MDCT. Measurement was done on the cortical areas (lingual, buccal, and posterior side) of the mandible and teeth 47 (email, dentin, and pulp) with 5 regions of interest (ROIs) on each area. DICOM software was used for the measurement on CBCT and MDCT data. The result indicated a strong correlation between pixel value in CBCT and HU in MDCT on the cortical bone and teeth area (R=0.846). Linear regression resulted in an equation to derive HU value from pixel value of cortical bone and teeth area, which is y = 1,9011x + 177,15. The conclusion is HU can be derived from CBCT by converting with regression equation.

Abstract

Objectives: This paper aims to determine the factors that influence the decision making of a general dentist to become a dentomaxillofacial radiologist, particularly in Indonesia. Material and Methods: This research used a descriptive design with survey techniques, and the research samples were residents of dentomaxillofacial radiology residency program and dentomaxillofacial radiologists in Indonesia. This research was conducted by the way respondents filled out questionnaires, based on the concept of marketing and purchasing on the expertise of dental radiology specialists. Results: There are variations in answers that are dominated by the value of product purchases as a dental radiology specialist is urgently needed. Conclusion: Dentomaxillofacial radiologist is a profession that is rarely found in Indonesia so it becomes a reliable job in the future as more experts are needed. The promotional activities of its residency program are still much of lack.

Abstract

Objectives: The purpose of this study was to report a case of mandibular cementoblastoma with radiologic approach and describe its characteristics. Case Report: A 32-year-old female came to the Hospital and complained of swelling of the left side of the lower jaw. Clinical examination showed a strong swelling in the buccal region of teeth 44-45, with the same soft tissue color as the surrounding tissue. In the picture cone beam computed tomography appears as a rounded lesion, the internal structure of the radiointermediet with clear and firm boundaries, surrounded by a halo radiolucent. Cementoblastoma radiodiagnosis is established. The patient was referred for surgery. Conclusion: Cementoblastoma was a benign tumor with radiographic characteristics in the form of clearly demarcated radiopaque lesion with radiolucent halo. Some early-stage lesions can show lower density.

Abstract

ABSTRACTIntroduction: Estimating age and sex through several radiographic methods have a significant role in the victim identification process. The mandibular ramus is thought to have a high degree of dimorphism and a close relationship with chronological age, which can be determined by ramus notch depth (RND). This study aimed to analyze the differences in RND between males and females and the correlation between age and RND based on panoramic radiographs. Methods: The type of study is an observational analytic cross-sectional study. The study sample comprised 70 radiographs (35 males and 35 females) aged 19-60 years with complete mandibular permanent dentition, including third molars. The samples were obtained from the database of the Dentomaxillofacial Radiology Installation of RSGM UGM Prof. Soedomo. Analysis of the radiograph was carried out by measuring the RND using EzDent-I Vatech Software with a scale of ratio 1:1. Results: The mean RND value was 2.31 ± 7.95 mm and 1.94 ± 4.93 mm in the male and female groups, respectively. Independent T-test results showed a significant difference (p < 0.05) in RND between the male and female groups. Pearson’s correlation test result did not find any correlation between age and RND in the male dan female group (p > 0.05). Conclusion: RND in males is higher than in females, and there is no correlation between age and RND in both sex groups.Keywords: MISS; trauma of mandible; half face helmet; traffic accidents

Abstract

ABSTRACTIntroduction: One of the sectors that has been significantly impacted by the COVID-19 pandemic is dentistry. There is a significant chance that an intraoral radiographic examination will facilitate the spread of the COVID-19. One of the radiographers' efforts to prevent the spread of the COVID-19 virus is to carry out infection control. The application of infection control performed by radiographers is influenced by many factors. This study aimed to analyze differences in the application of infection control in intraoral radiographic examinations during the COVID-19 pandemic in various healthcare facilities. Methods: This study conducted was an observational analytic study with a cross-sectional design. The research was conducted using a questionnaire consisting of 13 statement items. Thirty intraoral dental radiographers who were employed in radiology departments at various healthcare facilities participated in the study as respondents. The research data that had been collected was then tested using the One Way Anova test to find out the differences in the application of infection control by radiographers from each healthcare facility. Results: The results of the study indicated that the significance value was 0.314 (p>0.05), which means that there was no significant difference in the score category for each healthcare facility. The lack of complete respondents from all different kinds of existing healthcare facilities was still a weakness of this study. Conclusion: During the COVID-19 pandemic, there was no discernible difference in how each healthcare facility implemented infection control during intraoral radiographic examinations.KeywordCOVID-19, healthcare facilities, infection control, intraoral radiographs, radiographers

Abstract

Radiographic examination using intraoral bitewing (IOBW) radiography is an ideal examination to detect proximal carious lesions. Besides the risk of triggering gag reflex, the IOBW technique is susceptible to SARS-CoV-2 virus transmission through saliva-contaminated film or digital sensor. Examination using intraoral techniques during the COVID-19 pandemic should be avoided to minimize cross-contamination of the SARS-CoV-2 virus. The alteration from using IOBW to extraoral bitewing (EOBW) radiography can be a promising alternative to overcome these problems. This review article aims to describe the advantages of the EOBW technique and compares diagnostic performance of IOBW and EOBW radiographs in detecting proximal dental caries. The databases used for literature searching in the review include Google Scholar, PubMed, and Science Direct. The inclusion criteria were original articles, case reports, and English and Indonesian scientific textbooks published from 2010 to 2021. The exclusion criteria were article reviews and original articles that did not contain research methods. A total of 29 literatures were discussed in this narrative review. The EOBW technique is recommended during the COVID-19 pandemic to reduce the risk of cross-contamination in dental radiography. This technique ensures the patient for a more comfortable procedure, with shorter time needed and a wider field of view that allows it to be used to detect bone loss in the alveolar crest. Sensitivity, specificity, and area-under-curve in the IOBW technique were higher than in the EOBW. Nevertheless, EOBW shows good accuracy, so it can be used as an alternative technique for patients who find it difficult to undergo the IOBW technique, especially during the COVID-19 pandemic.

Abstract

Background: Sex estimation is the first step in identifying bodies following disasters or accidents. Craniometric analysis of lateral cephalograms can be used in the process. Among the measurements that can be used are the length of cranial base, determined by Basion–Nasion (Ba-N) length, and the total face height, determined by the Nasion–Menton (N-M) length, which can highlight significant differences between men and women. Purpose: This study aimed to determine the differences in length of cranial base and total face height measurements between men and women and to demonstrate how these two measurements can be used for sex estimation in the Indonesian population. Methods: This cross-sectional study employed a patient database from the dental hospital of Universitas Gadjah Mada. The study sample consisted of 116 cephalograms taken of 58 men and 58 women aged 20–40 years. The linear measurements were taken using EzDent-I Vatech software. Results: The mean cranial base length measurements in the men and women groups were 103.83 ± 4.37 and 96.01 ± 3.80 mm, respectively, whereas the total face height measurements were 121.03 ± 7.26 and 111.23 ± 5.09 mm, respectively. The Mann–Whitney U-Test revealed a significant difference (p < 0.05) between the groups. Logistic regression showed that the two measurements can be used to form an equation for sex estimation with an accuracy of 88.8%. Conclusion: Length of cranial base (Ba-N) and total face height (N-M) measurements from lateral cephalograms can accurately be used for sex estimation. Further research among specific populations is required to develop accurate methods for sex estimation employing morphometric examination on radiographs.
