Lesi periapikal adalah lesi yang berada di daerah apikal dan dapat dirawat dengan perawatan endodontik untuk mencapai penyembuhan. Proses penyembuhan lesi periapikal dapat dievaluasi dengan pemeriksaan radiografis dengan menggunakan radiograf periapikal. Tujuan penelitian ini adalah untuk mengetahui perubahan gambaran yang terjadi pada proses penyembuhan lesi periapikal pada radiograf periapikal menggunakan software ImageJ. Metode: Metode penelitian ini merupakan penelitian deskriptif yang menggunakan 30 arsip radiograf periapikal pada saat diagnosis, pengisian, dan kontrol perawatan endodontik yang terdapat di Instalasi PPDGS Konservasi Gigi RSGM Unpad. Proses penyembuhan ini dilihat dari luas dan densitas lesi dengan menggunakan software ImageJ. Hasil: Nilai rata-rata pengurangan ukuran luas lesi sebesar 13,25±10,77 mm2 dan peningkatan densitas rata-rata sebesar 9,95±7,26% yang dilihat dari foto diagnosis, pengisian, dan kontrol. Simpulan: Gambaran penyembuhan lesi periapikal terjadi pengurangan ukuran luas lesi terbesar pada tahap diagnosis ke pengisian dan peningkatan densitas terbesar pada tahap pengisian ke kontrol pada perawatan endodontik yang dilihat dari radiograf periapikal menggunakan software ImageJ.

Objectives: The aim of this case report is to explain further about radiograph on impacted right maxillary third molar and canine using CBCT 3D. Case Report: A 18 year old female patient came with swelling on her upper right posterior gum. The condition was associated with pus contained in the gum. Physical examination revealed no exact abnormalities condition on her teeth. Panoramic radiograph examination showed radiopaque image surrounded by radiointermediate image in maxillary sinus. The result of 3D CBCT radiograph exhibited radioopaque image resembling tooth 18 surrounded by unilocular radiointermediate filling 2/3 maxillary sinus with well-defined border.  Conclusion: CBCT is a supported examination which may help in establishing diagnosis more accurately.

Objectives: Dense Bone Island (DBI) is one of the lesions that are usually visualized on a panoramic radiographs in the form of total radiopaque in the periapical area of the mandibular premolar or molar but most of them are not directly related to the dentition. This case report is aimed to give summaries about the description of 3 DBI cases. Case Report: Three panoramic radiographs of patients with asymptomatic well-defined radiopaque lesions which was found incidentally in the periapical area of the left mandibular first premolar with two of them showing the lesions located exactly in the 1/3 apical of the root and one of them seen as root resorption like. From clinical information, all three cases reported no clinical symptoms and affected teeth are still vital. Conclusion: Incidental findings of well-defined radiopaque lesion in the periapical area of the premolar and molar of mandible that mostly do not damage the surrounding teeth lead to the diagnosis of dense bone island.

Pendahuluan: Tingkat perkembangan dan maturasi seorang pasien tidak dapat diketahui secara pasti dari usia kronologis, dikarenakan adanya variasi waktu percepatan pertumbuhan pubertas pada setiap individu, maka perlu ditentukan usia biologisnya. Usia biologis ini dapat ditentukan dari usia tulang berupa kualitas tulang yang dapat dilihat dari ukuran densitas tulang. Radiograf panoramik dapat menilai kualitas kepadatan (densitas) tulang secara makrostruktur dan mikrostruktur. Penelitian ini menggunakan sampel perempuan karena perempuan cenderung kehilangan densitas mineral tulang lebih cepat daripada laki-laki. Tujuan penelitian ini yaitu menganalisis korelasi usia kronologis dengan densitas tulang pada radiograf panoramik pada pasien perempuan. Metode: Jenis penelitian ini adalah cross-sectional, dengan menggunakan analisis korelasi. Populasi penelitian menggunakan data primer dari seluruh radiograf panoramik pasien perempuan usia 5-35 tahun pada bulan Desember 2016-Januari 2017 di Rumah Sakit Gigi dan Mulut (RSGM) Universitas Padjadjaran dengan jumlah sampel 64 orang. Analisis densitas tulang trabekula mandibula dilakukan dengan menggunakan software ImageJ dengan Region of Interest (ROI) 4x4mm pada tepi distal foramen mentale mandibula. Hasil: Rerata ukuran densitas tulang trabekula pada kelompok usia 5-11 tahun 17,54%, kelompok usia 12-16 tahun 21,06%, kelompok usia 18-25 tahun 24,01%, dan kelompok usia 26-35 tahun 25,96% dengan hasil korelasi Pearson r = 0,827, dan nilai p=0,0001. Simpulan: Terdapat korelasi antara usia kronologis dengan nilai densitas tulang trabekula pada radiograf panoramik pasien perempuan, yaitu semakin bertambahnya usia kronologis maka nilai densitas tulang juga akan semakin meningkat sesuai dengan rentang usia penelitian 5-35 tahun.Kata kunci: Usia kronologis, densitas tulang, radiograf panoramik, software imageJ. ABSTRACTIntroduction: The level of development and maturation of a patient can not be known with certainty from chronological age, due to variations in the time of pubertal growth spurt in each individual, it is necessary to determine the biological age. This biological age can be determined from bone age in bone quality, which can be seen from the bone density measurement. Panoramic radiographs can assess the quality of bone density macrostructure and microstructure. This study used a female sample because female tend to lose bone mineral density faster than male. This study was aimed to analyse the correlation between chronological age and bone density on female patients’ panoramic radiographs. Methods: This research was cross-sectional with correlation analysis. The study population used was the primary data from all panoramic radiographs of female patients aged 5-35 years in December 2016-January 2017 at Universitas Padjadjaran Dental Hospital (RSGM Unpad) with a total sample of 64 people. Mandibular trabecular bone density analysis was performed using ImageJ software with a 4x4mm Region of Interest (ROI) on the mandibular mental foramen’s distal edge. Results: The mean size of trabecular bone density in the 5-11 years age group was 17.54%, the 12-16 years age group was 21.06%, the 18-25 year age group was 24.01%, and the 26-35 years age group was 25.96%; with the results of Pearson correlation r=0.827, and the p-value = 0.0001. Conclusion: There is a correlation between chronological age and the value of trabecular bone density on the panoramic radiograph of female patients, that is, the increasing of chronological age will also increase the value of bone density, according to the age range of the study (5-35 years).Keywords: Chronological age, bone density, panoramic radiographs, image-J software.

ABSTRAKPendahuluan: Karies merupakan penyakit yang paling banyak terjadi, pada tahun 2013 kerusakan gigi masyarakat Indonesia adalah 460 buah gigi per 100 orang jika dibiarkan tidak dirawat akan berpogres mengarah pada kematian pulpa dan akan menyebar menyebabkan infeksi periapikal. Tahun 2010 penyakit pulpa dan periapikal menempati posisi ke 7 dari 10 penyakit terbanyak pada pasien rawat jalan di rumah sakit di Indonesia.

ABSTRACTIntroduction: Caries was a common disease, in 2013 tooth decay happened in 460 teeth among 100 peoples and if it left untreated it would lead into pulp necrosis and caused periapical inflamation. In 2010 periapical and pulpa disease placed in seventh position among ten most common disease in outpatients in Indonesia.. Radioraphic technique that could be use to diagnose a pulpal and periapical disease was periapikal technique. The purpose of this research was to get the information about radiographic image proportion of the periapical lession in tooth that already necrose through periapical radiograph at RSGM Unpad. Method: This type of research was descriptive. The study population was all radiographs of necrotic tooth with periapical lession in November 2018 -January 2019 at Dental Radiology Installation RSGM Unpad. Sample was determined by purposive sampling method. 54 samples of periapical radiographs were obtained on this research. Result: The result of this research showed that among 54 radiographs, 42 radiographs (77,28%) were periapical abscess, 8 radiographs (14,81%) were periapical granuloma and 4 radiographs (7,40%) were periapical cyst. Conclussion:Proportion of periapical lession through periapical radiograph at RSGM Unpad was periapical abscess as the highest proportion followed by periapical granuloma and periapical cyst.
