Kista dentigerous atau kista folikuler merupakan kista odontogenik yang terbentuk selama perkembangan gigi dan terbentuk karena akumulasi cairan di rongga folikuler pada gigi yang belum erupsi. Lokasi gigi-gigi yang sering berhubungan dengan kista dentigerous adalah gigi M3 rahang bawah, C rahang atas, P rahang bawah dan jarang pada gigi M3 rahang atas. Kista dentigerous yang berkaitan dengan gigi supernumerari dan sinus maksilaris sangat jarang ditemukan. Panoramik dan CBCT dapat dilakukan untuk melihat kasus kista dentigerous. Tujuan laporan kasus ini untuk melihat temuan kista dentigerous di rahang atas yang meluas sampai ke kavum nasi dan sinus maksilaris melalui gambaran CBCT dan panoramik radiograf. Laporan kasus: Seorang pasien laki-laki berusia 27 tahun datang ke RSGM Unpad untuk dilakukan CBCT-3D. Keluhan pasien yaitu bengkak di daerah langit-langit lebih dari 1 tahun yang lalu, bengkak meluas ke pipi sejak 1-2 bulan yang lalu. Keluhan bengkak tidak terasa nyeri. Konsistensi massa keras dan terasa nyeri saat ditekan. Hasil pemeriksaan CBCT dan histopatologi menyatakan bahwa lesi merupakan kista dentigerous. Simpulan: Kista dentigerous pada CBCT menunjukkan perluasan lesi ke kavum nasal dan sinus maksilaris serta tepi yang lebih jelas dibandingkan dengan radiograf panoramik. Kata kunci: CBCT, panoramik, kista dentigerous, kavum nasal, sinus maksilaris. Maxillary dentigerous cyst finding with expansion of the nasal cavity and maxillary sinus through the CBCT and panoramic radiographs ABSTRACT Introduction: Dentigerous cysts or follicular cysts are odontogenic cysts that form during tooth development and formed from the accumulation of fluid in the follicular cavity of an unerupted tooth. The teeth locations often associated with dentigerous cysts are the mandibular M3, the maxillary C, the mandibular P, and rarely occurred in the maxillary M3. Dentigerous cysts associated with supernumerary teeth and maxillary sinuses are extremely rare. Panoramic and CBCT can be performed to observe dentigerous cysts cases. This case report was aimed to examine the findings of a maxillary dentigerous cyst with expansion of the nasal cavity and maxillary sinus through CBCT and panoramic radiographs. Case report: A 27-yearsold male patient came to Universitas Padjadjaran Dental Hospital for CBCT-3D examination. The patient's complaint was swelling in the palate from more than one-year prior, extended to the cheek from 1-2 months prior. Complaints of swelling was not painful, although, when pressed, then a solid, painful mass will be felt. The results of CBCT and histopathological examination confirmed that the lesion was a dentigerous cyst. Conclusion: Dentigerous cyst on CBCT showed expansion of the lesion to the nasal cavity and maxillary sinus as well as more apparent margins compared to panoramic radiographs.

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.

Introduction: Clicking is the most common clinical symptom in patients with Temporomandibular Disorder (TMD). Lacking attention by either the patient or dentist, many patients were found to have suffered from morphologic alteration of the condyles seen in the panoramic radiograph inadvertently. The purpose of the study was to determine the differences of condyle morphology of the Temporomandibular Joint (TMJ) with and without the existence of clicking by means of digital panoramic radiographs. Methods: This study was based on an analytic descriptive research, whereas subjects are digital panoramic radiographs taken from clicking and non-clicking patients at the Radiology Installation of Dental Hospital Universitas Padjadjaran. 16 samples of each group were chosen in a non-random purposive sampling manner. Results: The research showed the mean of condyle morphology, HOC height  on clicking (6.31 mm) was shorter than the non clicking (7.63 mm), the width of HOC on clicking (10.38 mm) was higher than the non clicking (10.22 mm) and height of the processus condylaris on clicking (19.70 mm) was shorter than non clicking (20.04 mm). Ratio of the high of HOC, width of HOC and high of processus condylaris were 12.13 (clicking), and 12.63 (non-clicking). Conclusion: There was no significant difference between the morphology of the TMJ condyle between clicking and not clicking group, except on high of HOC.

Introduction: The third molar is undoubtedly the most variable tooth in the human dentition, and also the most common tooth to become impacted due to it being the last tooth to erupt into the dental arch The aim of research is to obtain the prevalence of the mandibular third molar (M3) impaction among the patients attending the Radiology Clinic. Methods: The type of research conducted was a descriptive research. The sampling was purposive, drawn from a population of 1451 digital panoramic radiographs taken from January – December in the year 2010, of which 392 samples were included in the survey, with patient ages ranging between 18 – 59 years at time of exposure. The position of the M3’s was assessed using the Pell and Gregory and, Winter’s impaction classification. Results: The prevalence of impacted mandibular M3’s in this study is 76.8% overall. Of the impacted mandibular M3’s present, 76.1% were bilateral impactions and of these bilateral impactions 50.7% are similar in impaction classification. Of the mandibular M3’s examined, 40.1% are in a vertical angulation, 33.3% mesioangular, 23.5% horizontal and 3.1% distoangular. The three most common types of impaction according to the Pell and Gregory classification are IIB at 38.5%, IA at 36.8% and IIA at 18.8%. Conclusion: Prevalence of  mandibular third molar of the patients attending the Radiology Clinic is 76.8%.
