The professionalism of the radiologist greatly influences the results of radiological images. The quality of panoramic radiography greatly influences accurate clinical diagnosis. The correct patient position is one of the many factors that affect high-quality and accurate panoramic radiography. The process of taking radiographic images causes radiation exposure to the patient, so that when taking radiographic images repeatedly it is very bad for the patient. A review research is needed to reduce radiation exposure by improving the quality of panoramic radiography. This research conducted a literature review by proposing the questions (1) What types of position errors in panoramic radiography have been researched? (2) How is the process of identifying position errors in panoramic radiography that have been researched? The results of the review research showed that the types of position errors in panoramic radiography that have been researched are the head turning, the tongue not sticking to the palate, the chin down, the chin not resting on the support. The process of evaluating position errors in panoramic radiography is mostly done manually, there is only one research that identifies position errors in panoramic radiography automatically using SVM. That there is a great opportunity to create an automatic system for identifying position errors in panoramic radiography to be more precise and time efficient.

Introduction: One of the parameters for measuring craniofacial growth is suture closure. The sutures are connected with fibrous connective tissue that grows in a few days. The objective is to analyze the gray-scale value (GV) potential by measuring the volume of interest (VOI) of the different skulls using micro-computed tomography (Micro-CT). The analysis uses certain parameters, namely density and thickness. Material and Methods: This study involves experimental mice to examine normal growth and development processes at a certain age by investigating mice’s suture maturation. If the suture closure process has been completed, it can be used as a potential standard for measuring the cessation of growth in the craniofacial area. This study examined three different skulls obtained from 15-day-old (cranium 1) baby mice, 25-day-old (cranium 2) baby mice, and 120-day-old adult mice (cranium 3). The possible GV was 0 to 255 (Micro-CT-reconstructed image dataset in 8-bit-BMP-format). There was a volumetric space that limited the analysis area of the bone tissue whose density was measured. In micro-CT-reconstructed images, VOI was determined by the region-of-interest (ROI) in the 2D image slices, which completely formed an image. The machine used was a Bruker SkyScan 1173 high energy micro-CT. Results and Discussions: The suture of Cranium 1, Cranium 2, and Cranium 3 have a relative mean density (GV) of 32,45; 29,74; and 50,1, respectively. This study also measures the geometric average measurement of bone cranium thickness with a 5x5 mm cross-section. The average thickness of cranium 1 is 0.554 mm, cranium 2 is 0.645 mm, and cranium 3 is 1.417 mm. Conclusion: Sutures cranium 1 and 2 are lower in density and thinner than cranium 3 as documented by means of Micro-CT.

In this study, an adult rat's calvaria was used to examine craniofacial anatomical landmarks of maxilla and mandible using Micro-Computed Tomography (micro-CT) as the marker of craniofacial growth and development in rat. It is used to assist research, translating landmark points for diagnosis. Landmarks on the rat’s calvaria were determined to set the measurements of two specified points. One of the ways to validate craniofacial growth and development is to look at the differences between craniofacial before and after a specified period or treatment. With micro-CT analysis, the researchers are more precise in determining the difficult points in the cranium.The sample analysis was carried out and measured by DataViewer version 1.6.0.0 64-bit Application. CTVox version-3.3.1 64-bit is used to display 3D visuals. Reconstruction results after adjusting the data range were 30-255 (the color range 0-255). The machine used was Bruker SkyScan-1173 High Energy Micro-CT. Findings anatomical landmarks for the examples, the maxilla determined I for the point on premaxilla between jawbone and lingual surface of upper incisors. In the mandible, I’ for the most anterior edge of the alveolar bone on the convexity of the lower incisor. The unevenness of the cranium made manual measurements difficult and not possible. However, this micro-CT method makes the landmark point determination more detailed and dependable. This makes geometric measurements of craniofacial more reliable. Micro-CT analysis is a more dependable method to determine anatomical landmarks and measure craniofacial structures as the marker of craniofacial growth and development in rat.

Introduction: CBCT-3D (Cone Beam Computed Tomography) is an advanced radiographic imaging technology that is currently being developed and utilized in dentistry, with the advantages of accurately depicting three-dimensional (3D) tissue structures, minimal distortion, and low radiation dose. RSKGMP Universitas Airlangga is an educational dental hospital and one of the few hospitals in Surabaya city and also East Java Province that provides CBCT-3D examination services for various cases- thus becoming a referral center for the radiographic examination in the region. A lot of clinical case referrals have been recorded, but no one has researched the distribution of clinical cases referred for CBCT-3D examination. Objective: This study is aimed to determine the distribution of clinical cases referred for CBCT-3D radiographic examination at RSKGMP Universitas Airlangga based on origin, age, and gender. Methods: This study is a descriptive study with a sample of all clinical case medical records, CBCT-3D examination reference data at RSKGMP Universitas Airlangga from July 2015 to March 2020, which met the sample criteria. Furthermore, the data is tabulated and displayed using pie charts and bar charts. Results: Most referrals for CBCT-3D radiography came from internal referrals of RSKGMP Universitas Airlangga (78%). The elderly patients (46 years and over) had the most referrals (59%) of all age groups with the most indication for implant cases (78.9%). Female patients slightly more dominated the total referrals (57.5%) than male patients (42.5%). Conclusion: Most of the clinical cases of referral for CBCT-3D radiographic examination were implants and came from internal RSKGMP Universitas Airlangga, with the most referral age category being elderly and dominated by female patients.
