IDENTIFIKASI USIA MANUSIA BERDASARKAN CITRA Panoramic Radiograph GIGI KANINUS RAHANG BAWAH MENGGUNAKAN METODE WATERSHED DAN KLASIFIKASI SUPPORT VECTOR MACHINE
Universitas Telkom Fakultas Teknik Elektro, 2019Co-Authors: Ayu Tri YulinaAbstract:Penentuan usia seseorang memegang peranan penting dalam kedokteran forensik, tidak hanya untuk identifikasi tubuh, tetapi erat juga kaitannya dengan tindak kejahatan dan kecelakaan, akibat dari tindak kejahatan dan kecelakaan ini, tidak jarang ditemukan kerangka manusia atau korban yang sulit diidentifikasi. Banyak prosedur dapat ditempuh dalam menentukan usia seseorang dalam hal ini penelitian saya memfokuskan identifikasi usia manusia melalui gigi tepatnya pada luas pulpanya. Pengukuran besar pulpa diambil dengan Panoramic Radiograph, Radiografi panoramik telah lama menjadi satu dari sekian banyak teknik radiografi yang unggul di kalangan dokter gigi untuk digunakan dalam mengambil Gambar struktur gigi karena berbagai kelebihan yang dimilikinya. Radiografi panoramik memberikan tampakan dua rahang gigi dan tampakan jelas beberapa strukturanatomis seperti sinus maksila, temporomandibular joint, dan tulang hyoid. Selain itu, pengambilan radiografi panoramik juga mudah untuk dilakukan dan dapat diaplikasikan pada pasien yang mengalami keterbatasan dalam membuka mulut. Tugas akhir ini dibuat bertujuan untuk mengestimasikan usia manusia dengan teknik radiograf panoramik gigi kaninus rahang bawah mengggunakan metode segmentasi Watershed, Metode ini merupakan metode yang cukup baik dalam menganalisis hasil segmentasi sebuah citra. Untuk mengklasifikasinya menggunakan metode support vector machine. Hasil performansi dari sistem tersebut diperoleh dengan tingkat akurasi sebesar 91% dan waktu komputasi 0.0111 dengan menggunakan 141 sampel citra latih dan 47 sampel citra uji. Dengan adanya sistem ini dapat bermamfaat untuk dunia medis terutama untuk odontologi forensik dalam melakukan identifikasi usia manusia. Kata Kunci : Panoramic Radiograph, Watershed, Support Vector Machin

Many procedures can be taken in determining the age of a person in this case my research focuses on the identification of human age through teeth precisely in the area of the pulp. This final project was made to identify human age by using a mandibular canine Radiograph Panoramic technique using Watershed segmentation method. This method is a fairly good method in analyzing the results of segmentation of an image. To classify it using the support vector machine method. The performance of the system resulted with 91% accuracy rate and 0.0111s computation time using 141 training image samples and 47 test image samples. The existence of this system could make benefit for the medical world especially for forensic odontology in identifying human age. Keywords: Panoramic Radiography, Gabor Wavelet, K-Nearest Neighbor

prevalence location and size of maxillary sinus septa Panoramic Radiograph versus computed tomography scan
Journal of Oral and Maxillofacial Surgery, 2011Co-Authors: Laura Maestreferrin, Celia Carrillogarcia, Sonnica Galangil, Maria PenarrochadiagoAbstract:Purpose To determine the prevalence, location, and size of maxillary sinus septa, and to compare the results of Panoramic Radiographs and computed tomography (CT) scans. Materials and Methods This study included 30 patients, 17 women and 13 men, with a mean age of 50.9 years (range, 28-73 years), undergoing treatment planning for implant-supported restorations in the maxilla. Three observers analyzed the Panoramic Radiographs, the conventional CT scans in acetate, and the Implametric 3-dimensional CT (3Dent, Valencia, Spain). The maxillary sinus septa of each patient and the type of septa, as well as its location and size, were recorded. Results In 60 maxillary sinuses, Panoramic Radiographs showed 32 septa (53.3%); CT in acetate showed 42 septa (70%); and Implametric 3-dimensional CT showed 40 septa (66.7%). Most septa (60%) were located in the middle region of the maxillary sinus, 22.5% in the posterior region, and 17.5% in the anterior region. The mean height of the septa was 4.78 ± 1.76 mm. Panoramic Radiographs led to an erroneous diagnosis in 46.5% of the cases. Conclusions Maxillary sinus septa are a frequent anatomic variation. They can be found in any of the maxillary sinus regions independently of patient edentulism. The Panoramic Radiograph can lead to false-positive and false-negative findings in the visualization of septa in almost half of cases. Therefore, whenever a maxillary sinus lift is planned, a thorough study of the affected sinus should be made using CT.

elongated styloid process evaluation on digital Panoramic Radiograph in a north italian population
Journal of Clinical and Experimental Dentistry, 2017Co-Authors: Antonio Gracco, Giovanni Bruno, Alberto De Stefani, Paolo Balasso, Giulio Alessandribonetti, Edoardo StelliniAbstract:BACKGROUND The aim of this study is to evaluate the prevalence of elongated styloid process in digital Panoramic Radiographs in a North Italian population in relation to age, gender and side. MATERIAL AND METHODS This study was performed as a retrospective analysis on digital Panoramic Radiographs of 600 (271 males and 329 females) Italian patients between 6 and 87 years old. The styloid process length were measured using the measuring tool of Sidexis Software. It was measured from the point where it left the temporal bone plate to its tip. Styloid processes measuring more than 30 mm were considered elongated. Chi-squared and Fisher tests were used and the test is considered significant if the p-value is lower or equal to 0.05. RESULTS Thirty-three per cent of the patients showed an elongated styloid process. Seventeen per cent were elongated on both right and left side, fifteen point nine per cent were elongated only in one side. CONCLUSIONS The prevalence of elongated styloid process was high and a progressive increase of the elongation prevalence was found in older groups. Key words:Elongated styloid process, Eagle's syndrome, Panoramic Radiograph.

how to detect opacities in the orofacial soft tissue on a Panoramic Radiograph heterotopic ossifications and foreign bodies
Nederlands Tijdschrift Voor Tandheelkunde, 2019Co-Authors: E H Van Der Meij, W E R Berkhout, G C H Sanderink, J G A M De VisscherAbstract:Opacities in the orofacial soft tissue rather than the bone are frequently seen on Panoramic Radiographs. The differential diagnosis of these opacities is diverse and concerns frequently occurring disorders but also rare ones. Due to the diversity of diagnoses, the clinical interpretation of a soft tissue opacity is often difficult. A distinction is made among heterotopic calcifications, heterotopic ossifications, and foreign bodies. Heterotopic calcifications are subdivided into 3 groups, i.e. dystrophic, idiopathic and metastatic calcifications. In this article, stress is placed on the Radiographic and clinical characteristics of heterotopic ossifications and foreign bodies, and how they can be recognised on a Panoramic Radiograph. Besides this, attention will be paid to the need for possible additional imaging techniques and indications regarding treatment option.

how to detect opacities in the orofacial soft tissue on a Panoramic Radiograph dystrophic calcifications
Nederlands Tijdschrift Voor Tandheelkunde, 2019Co-Authors: E H Van Der Meij, W E R Berkhout, G C H Sanderink, J G A M De VisscherAbstract:Opacities not in the bone but in the orofacial soft tissue, are frequently seen on Panoramic Radiographs. The differential diagnosis of these opacities is diverse and concerns frequently occurring disorders but also rare ones. Due to the diversity of diagnoses, the clinical interpretation of a soft tissue opacity is often difficult. A distinction is made among heterotopic calcifications, heterotopic ossifications, and foreign bodies. Heterotopic calcifications are subdivided into 3 groups, i.e. dystrophic calcifications, idiopathic calcifications, and metastatic calcifications. In this article, stress is placed on the Radiographic and clinical characteristics ofidiopathic calcifications and how they can be recognised on a Panoramic Radiograph. Besides this, attention will be paid to the need for possible additional imaging techniques and indications regarding treatment options. Idiopathic calcification results from deposition of calcium salts in healthy tissue without an apparent cause. Calcium and phosphate levels in the serum are normal in these cases.
