Abstract

Post-menopausal woman has a high risk to have osteoporosis. The condition of osteoporosis is characterized by the bone mineral density. The gold standard of BMD examination is using DEXA scan, but it has a problem in high cost and limited availability. So the study about the alternative to overcome the problem is necessary. The objective of this study is to measure the maximum value of periapical radiograph and determine its ability to be a predictor for bone mineral density of lumbar spine and hip.Image processing method was applied to 37 data subject that involved periapical radiograph and DEXA scan. The grayscale image was converted into binary image to observe the connectivity of the pixels. Measurement of maximum value for each radiograph has been done and continued by linier regression method between the maximum value with the BMD of lumbar spine and hip.The result of this study showed that the maximum value has a weak correlation with the BMD of lumbar spine and hip. The maximum value also cannot be the predictor for BMD of lumbar spine and hip as the significant of F is larger than 0,05 in the linier regression test.

Abstract

Background: An obstacle in forensic odontology is an incomplete body caused by post-mortem damage. The problem can be solved by using lateral cephalometric radiographs for victim identification. Sex determination can be performed on the maxillary sinus, which is the largest among the paranasal sinuses. Purpose: This study aims to analyse the maxillary sinuses’ width and height on lateral cephalometric radiographs among male and female subjects. Methods: The study samples were 60 lateral cephalometric radiographs (30 males and 30 females) between the ages of 20 and 40, with complete permanent dentition (or third molar absence). The height and the width of maxillary sinus measurement were performed using measurement tools of EzDent-i Vatech Software. Results: The average width of the maxillary sinus on males was 40.60 ± 1.56 mm, and the height was 35.02 ± 2.09 mm, while the width and the height on females were 36.93 ± 1.30 mm and 29.72 ± 1.76 mm, respectively. The independent t-test reveals a significant difference (p<0.05) between males and females, both in the maxillary sinus’s width and height on the lateral cephalometric radiograph. Conclusion: The maxillary sinus in males is larger than in females, it opening up possibilities for disaster victim identification.

Abstract

Objectives: Panoramic radiography exposure causes DNA damage and micronucleus formation. The gingival mucosa and buccal mucosa were used to identify the number of micronucleus due to radiation exposure because they have a high prevalence of oral cancer in Southeast Asia. This research is aimed to determine the difference between micronucleus formation at the buccal mucosa and the gingival mucosa after exposed by conventional panoramic radiography in the Dentomaxillofacial Radiology Installation of Prof. Soedomo dental hospital, Universitas Gadjah Mada. Material and Methods: Samples were obtained by rolling the cervical brush against the buccal and gingival mucosa at 10 days after radiation exposure. Samples were stained using the Feulgen-Rossenbeck method and analyzed under binuclear light microscope with a 400x magnification. Results: Analysis of independent T tests showed that there was a significant difference (p<0,05) in the increasing of micronucleus formation between the buccal mucosa and the gingival mucosa. The average difference in the number of micronucleus were 5,5/1000 cells. Conclusion: There were differences in the increasing of micronucleus between the buccal mucosa and the gingival mucosa due to exposure of conventional panoramic radiography. The buccal mucosa had higher increase than the gingival mucosa.

Abstract

Objectives: The aims of this review is to describe thyroid shield function and to look the dentists’ perceptions considering the application in dental radiographic examination, particularly in cephalometric and Cone Beam Computed Tomography (CBCT) examination. Literature Review: The utilization of thyroid shield has been signified reduction of radiation dose about 34% in cephalometric examination and 18-40.1% in CBCT. The absence of universal guidelines has led to minimal perception of dentists on the importance of using thyroid shield as indicated by the low utilization of thyroid shield among patients. This low perception can be improved through adequate education and applied training in the use of thyroid shield. Conclusion: Dentists’ perceptions regarding the application of thyroid shield need to be improved so that the application of thyroid shield can be increased in order to protect patients from the risk of dental radiation exposure.

Abstract

Objectives: This narrative review is written to describe the accuracy of caries detection and find out the clinical implications and future prospects of using Convolutional Neural Network (CNN) to determine radio-diagnosis of dental caries in bitewing and periapical radiographs. Review: The databases used for literature searching in this narrative review were PubMed, Google Scholar, and Science Direct. The inclusion criteria were original article, case report, and textbook written in English and Bahasa Indonesia, published within 2011-2021. The exclusion criteria were articles that the full text could not be accessed, research article that did not provide the methods used, and duplication articles. In this narrative review, a total of 33 literatures consisting of 30 articles and three textbooks reviewed, including four original articles on CNN for caries detection. Conclusion: Results of the review reveal that GoogLeNet produces the best detection compared to Fully Convolutional Network (FCN) and U-Net for caries detection in bitewing and periapical radiographs. Nonetheless, the positive predictive value (PPV), recall, negative predictive value (NPV), specificity, F1-score, and accuracy values in these architectures indicate good performance. The differences of each CNN’s performances to detect caries are determined by the number of trained datasets, the architecture’s layers, and the complexity of the CNN architectures. The conclusion of this review is CNN can be used as an alternative to detect caries, increasing the diagnostic accuracy and time efficiency as well as preventing errors due to dentist fatigue. Yet the CNN is not able to substitute the expertise of a radiologist. Therefore, it is need to be revalidated by the radiologist to avoid diagnostic errors.

Abstract

An experiment to investigate the influence of synthetic dye contrast agent in photoacoustic imaging of biological tissue was conducted in this study. This study uses a simple phocoacoustic imaging system consists of three main components, i.e., a diode laser, condenser microphone, and a custom-build X-Y stage. Characterization was performed on the main components of the system to obtain the appropriate settings on imaging the biological tissue in this study. The results of the optimal frequency and duty cycle for laser modulation in this study were 19000 Hz and duty cyle of 40%, respectively. The addition of a contrast agent aims to improve the quality of the image by comparing the sample with methylene blue contrast agent, the sample with methyl red and the sample without contrast agent. The increases of acoustic intensity level is in proportion with the contrast agent concentration. The difference in the photoacoustic images reveal that the sample with methylene blue contrast agent has the highest acoustic intensity level compared to both sample with methyl red contrast agent and the sample without contrast agent. Therefore, this research proves that a photoacoustic imaging system can be developed to image biological tissue with a contrast agent and methylene blue has greater potential than methyl red to be used as a contrast agent in photoacoustic imaging.

Abstract

Latar Belakang: Penurunan jumlah gigi dan oklusi gigi posterior dapat memengaruhi kemampuan mengunyah yang dapat berakibat pada berkurangnya asupan nutrisi. Hal ini dapat berdampak pada aktivitas otot, terutama masa dan kekuatan otot yang tercermin melalui kekuatan genggaman tangan.Tujuan: Mengetahui hubungan antara jumlah gigi dan jumlah oklusi gigi posterior dengan kekuatan genggaman tangan populasi lansia di Yogyakarta.Metode: Penelitian observasional dengan rancangan cross sectional dilakukan pada 75 lansia berusia ≥60 tahun. Pemeriksaan rongga mulut dilakukan oleh empat dokter gigi terlatih. Pemeriksaan Indeks Masa Tubuh dan pemeriksaan fisik dilakukan oleh dua higienis gigi terlatih. Gigi dihitung dengan menjumlahkan gigi asli, jumlah oklusi gigi dihitung menggunakan Index Eichner’s. Indeks Masa Tubuh (IMT) dihitung dengan satuan kg/m2. Kekuatan genggaman tangan diukur menggunakan hand dynamometer dalam satuan kilogram. Tingkat aktivitas fisik dievaluasi menggunakan kuesioner terstandar IPAQ. Uji chi-square dan regresi logistik digunakan untuk mengetahui hubungan antara jumlah gigi, jumlah oklusi gigi dan variabel covariat dengan kekuatan genggaman tangan.Hasil: Uji Chi-square menunjukkan tidak terdapat perbedaan kekuatan genggaman tangan antara subjek yang memiliki jumlah gigi ≥20 dan <20 serta antara subjek dengan ≥2 dan <2 zona oklusi gigi posterior. Faktor risiko penurunan kekuatan genggaman tangan adalah aktivitas fisik (OR= 6,342, p=0,010). Kesimpulan: Mempertahankan jumlah gigi ≥20 dan aktivitas fisik bermanfaat untuk mempertahankan kesehatan oral dan sistemik.
